Vehicle was inoperable and over 100F in our driveway, with a flashing "critical high voltage battery fault". My wife injured her hand attempting to get in the vehicle. The service center has claimed that moisture inside the HVAC system caused the High Voltage (HV) battery system to fail, throwing a critical high-voltage battery fault. Rivian is attempting to deny warranty coverage based on this mo
... isture. Linkage to Warranted Component: At 85,690 miles, my vehicle is fully covered under Rivian’s 8-year High Voltage Battery Limited Warranty. The critical high-voltage fault and subsequent component failures were directly caused by water entering the electrical/battery system. Proximate Cause via Known Manufacturing Defect: Rivian has an active Technical Service Bulletin (TSB) regarding moisture ingress via the HVAC assembly for 2022–2024 R1S models. The moisture that caused the battery fault is a documented, inherent design defect of the vehicle, not user negligence or external environmental damage. An inherent defect in an out-of-warranty system cannot be used to void coverage for a failure it causes inside a component that is still heavily protected by an active warranty. The photograph provided by the service center does not depict superficial 'moisture in the HVAC' causing external damage. It shows severe fluid ingress and terminal corrosion inside the Woory Industrial High Voltage Cabin Heater assembly. Because this is an internal, high-voltage powertrain component operating directly off the traction battery system, it falls squarely under Rivian's 8-year / 175,000-mile High Voltage System Warranty. The corrosion present on the high-voltage circuit board is a direct result of the factory HVAC water ingress defect acknowledged in Rivian's technical service bulletins for 2022-2024 R1S vehicles. A manufacturing defect that allows water to breach a sealed, high-voltage housing cannot be used to deny warranty coverage on a high-voltage system that is actively wRead more

I am filing a complaint regarding my 2014 Dodge Dart involving an open recall related to the vehicle's shift cable/park system. On May 29, 2026, I pulled into a parking space and attempted to shift into Reverse to straighten the vehicle. At that point, the vehicle became stuck in Drive and would not shift into Park, Reverse, or Neutral. I was unable to remove the key from the ignition, and the ve
... hicle could not be safely operated. I had to secure the vehicle using the emergency brake and arrange for it to be towed. After contacting Dodge City of McKinney, I was advised to have the vehicle towed to the dealership for inspection. The dealership later informed me that Recall V34 had been completed in 2021 before I owned the vehicle, but that there is now an open A0C recall involving the shift cable/park system. I was advised that the recall remedy and parts are not yet available The dealership inspected the vehicle and documented that the shift cable/grommet is deteriorated. They stated in writing that the vehicle is not roadworthy and provided an estimate of approximately $756.70 to repair the condition. I was advised that I may need to pay for the repair myself and seek reimbursement later because the recall remedy is not yet available. I have opened a case with Stellantis Customer Care and have written documentation from the dealership confirming the vehicle is not roadworthy due to the shift cable condition. My concern is that the vehicle has been deemed unsafe to drive due to a condition involving a system that is currently subject to an open safety recall, yet I am being told to pay out of pocket for repairs while the official recall remedy remains unavailable. I am requesting review of the recall status, clarification of my rights, and assistance in resolving this matter without requiring out-of-pocket payment for a potentially recall-related repair.Read more

We lease a 2026 Palisade with only 4k miles. Several weeks ago I was going through a toll plaza, car would not accelerate after slowing down, as if it was in neutral. All of a sudden it kicked into gear and car lunged forward. 10 min later at a traffic light car failed to accelerate after a complete stop. Press the accelerator sluggish response, then kicked back into gear. Very Scary. I pulled
... over and notified the dealer. Then set an appoint. Dealer did a diagnostic, found no issues, could not replicate problem on test drive . Everything was fine a few weeks. My son took the car. Had the same exact issue with vehicle not accelerating. Then kicked into gear really hard and vibrating. This was scary for him because he was in a parking lot. Luckily there was no accident as a result. However, this time an error code (check engine light) came on and the Hyundai app showed a DTC CODE- P001600 (powertrain / engine). Car was immediately taken to dealer on May 28th 2026. It is now Jun 11th. Still no time frame for fix. The THINK it a software issue and Hyundai is still "working" on a solution.Read more

I am submitting this complaint regarding my 2020 Chevrolet Blazer and what appears to be a widespread cooling system defect. My vehicle has developed a coolant smell outside the vehicle, which raises concerns about a coolant leak from the radiator. After researching the issue, I discovered that numerous Chevrolet Blazer owners have reported similar coolant-related problems, including radiator fai
... lures, coolant leaks, and persistent coolant odors. These complaints are widely discussed across online forums, social media, and owner groups. General Motors appears to be aware of this recurring issue, yet many owners continue to experience failures within and outside of warranty coverage. The coolant smell is concerning because it may indicate a leak within the cooling system, which could lead to overheating, engine damage, loss of vehicle reliability, and potential safety risks while driving. Owners should not be experiencing major cooling system failures on relatively modern vehicles. I request that NHTSA investigate the cooling system and radiator issues affecting the 2020 Chevrolet Blazer and determine whether a defect exists that warrants a recall or other corrective action. The number of similar complaints suggests this may be a systemic issue rather than isolated incidents. General Motors should be held accountable for addressing this widespread problem and providing a permanent repair solution for affected owners. Thank you for your attention to this matter.Read more

I have not had an actual vehicle accident as of yet but the vehicle has a serious hesitation issue during acceleration from a quick stop or rolling situation whereas if you were making a left turn at a traffic light and were waiting for traffic while execrating to clear the next on coming vehicle there is sometimes a 3 second or more delay before the vehicle will accelerate which could cause an ac

Toyota has recognized this issue and came out with a technical service bulletin (T-SB-0032-26) with an update program for the TCU but has not included my vin or several others that have this same issue. I have been told by my dealer that they could do the update but since my vin is not included they would have to charge me. This is a major safety issue and needs to be addressed at no cost to the consumers. I have contacted Toyota brand engagement and they were no help at all acting like they had no idea what I was talking about. It happens every, everywhere. Major safety issue.

I did not have an incident yet. I was advised by my local State representative Jimmy Gordon's office. They stated were unable to help me get reimbursement for the $8000 I just paid my Kia dealer, but that I should make a complaint on this website. What happened is that I was hearing an odd noise and it was slipping. I went in thinking it was my tires and it needed alignment- so I had them replace
... d , etc in April. But the sound was still there so I went back in . Then the Kia St Cloud dealer diagnosed that the AWD transfer case was the cause (pd $4704 including $130 surcharge! ). When dealer called to say it was ready, they said bad news- your transmission is also damaged (pd $3197 including $90 surcharge ! ). This is a known failure of Kia/Hyundai models and needs to be addressed. You can lose control of your car and there could be an accident, especially on busy highways! I appealed to Kia corporate and also BBB auto line, but they both denied because too many miles (130k). The sound I heard /issue with transfer case & transmission happened as soon as my powertrain warranty was over! This is not right! I was someone who had given this vehicle 5 stars! I am the only owner and a multi- Kia owner who only brought this vehicle to a Kia dealer for all work. I have all records and that info was why Kia corporate originally told me i had "justification " for a goodwill reimbursement. [I currently am unemployed so I had to put all the repairs on a credit card (which meant being charged a 2.9% surcharge without informing me at the counter!)]. I hadn't heard so called June 2nd to Kia customer care and they said it was denied after all and would not give me any info except that they had negotiated with the dealership and it came back denied! I tried to call the GM at the dealer , but no answer back from my voice mail to Hector. Then BBB AUTO LINE also told me ineligible due to mileage. Well, this is still a dangerous issue and needs to be addressed!Read more

While driving a 2021 Honda CR-V Hybrid, the vehicle has intermittently and without warning lost the ability to accelerate. When this occurs, depressing the accelerator pedal — even fully to the floor — produces no response, and the vehicle simply coasts and loses speed. This has happened on three occasions — January 13, 2025; December 16, 2025; and June 10, 2026 — including at highway spee
... d. Each occurrence is documented by a Honda dealer service invoice. In each instance, the check engine light began flashing immediately before the loss of power. The only way to restore normal operation was to bring the vehicle to a stop, turn the ignition off, wait, and restart. Restarting restores power but also clears the check engine light and any stored diagnostic trouble codes. Safety risk: Losing motive power without warning, particularly at highway speed or while merging in traffic, creates a serious risk of a rear-end or loss-of-control collision, because the vehicle cannot accelerate out of danger. The affected systems appear to be the power train and hybrid propulsion system, possibly originating from the engine given the flashing check engine light, which typically indicates an active engine misfire. The exact failed component has not been confirmed (UNKNOWN). The problem has NOT been reproduced or confirmed by the dealer during inspection. The vehicle was taken to an authorized Honda dealer for each occurrence, but because restarting the vehicle clears the fault codes, the dealer found no stored codes and could not duplicate the failure during a test drive. The vehicle has not been inspected by the manufacturer, police, or insurance. The vehicle is available for inspection upon request. This matches NHTSA Preliminary Evaluation PE25016 regarding intermittent loss of motive power in MY 2020–2022 Honda CR-V Hybrid vehicles.Read more

The contact owns a 2016 Ford F-150. The contact received notification of NHTSA Campaign Number: 26V237000 (Power Train); however, the part required for the recall repair was unavailable. The contact stated the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while driving at approximately 40 MPH, the vehicle suddenly ran rough and shifted into n
... eutral(N). The contact depressed the accelerator pedal, but the vehicle failed to respond and entered LIMP mode. The contact was able to pull over to the side of the road, where the brakes were applied, and the vehicle was turned off. After about half an hour, the contact's son arrived and assisted the contact in driving to a nearby parking lot. The vehicle was then driven to the dealer below 40 MPH. The service traction control and power train warning lights illuminated. The dealer informed the contact that no diagnostic trouble code was retrieved; however, the contact was charged for the diagnostic test. The contact stated that the failure occurred twice, and the vehicle became operable. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 126,112.Read more

2021 Acura TLX Type S SH-AWD. Total mechanical failure of PTU/transfer case spline interface at 29,800 miles within factory powertrain warranty. Vehicle operated silently in FWD-only with no warning lights, no fault codes, and no dashboard alerts — consistent with all complaints cited in NHTSA Defect Petition DP26001 (opened March 6, 2026, NHTSA #11712885). Failure confirmed by dealer via lift
... test: propeller shaft and rear wheels stationary while fronts spun. During actuator test, Check AWD System light illuminated for the first time — because the lift removed road-induced wheel rotation that had masked the failure from the ECU throughout normal driving. This is the only condition under which this failure mode is electronically detectable. Dealer replaced transmission (remanufactured ATR kit) and PTU under warranty. Repair took 38 days. CRITICAL-THIRD PTU REVISION: Replacement PTU installed was part #29000-5YK-070. Known revision history: -050 (original, confirmed failure part) → 060 (revised ~2022) → 070 (installed June 2026). The 070 does not appear in any public OEM parts database. Acura has now revised this component three times with zero TSBs, zero public disclosure of engineering changes, and no recall. The 070 revision appearing after DP26001 opened in March 2026 suggests a silent root cause fix while avoiding formal recall obligations. CRITICAL-DPSM GOODWILL CLAUSE: Acura required acceptance of "One Time Goodwill Authorized by DPSM" as condition of repair. This was a warranty obligation, not a goodwill gesture. This clause was imposed while DP26001 is under active federal review, before factory warranty expires, with no confirmed root cause fix. If the 070 part fails again, this clause may be used to deny future warranty coverage. Requesting: (1) complaint added to DP26001 record; (2) Acura compelled to disclose engineering changes between part numbers 050, 060, 070; (3) investigation of DPSM Goodwill clause as systematic pre-recall liability limiationRead more

Following the completion of an official emissions recall software upgrade at Fitzgerald Auto Mall Countryside, Clearwater Florida, my 2017 Hyundai Santa Fe Sport (52,000 miles) now suffers from a severe loss of motive power and erratic transmission shifting/jerking during cold starts throughout day. The vehicle continues to hesitate during cold starts, making it impossible to safely accelerate f
... rom a stop into incoming traffic. I returned to dealership on 5/29/26 to address continued driving issues. The servicing dealership states they don't have a software fix and offer no mechanical fix. The dealership states they received an internal memo from Hyundai Corporate which instructed the dealership to tell affected owners to idle the vehicle for 1-3 minutes before driving to allow system adjustments. Forcing a consumer to wait out a dangerous powertrain defect in a running vehicle to avoid a roadway acceleration/loss accident is an unacceptable safety hazard. The manufacturers recall update has actively compromised the safe operation and motive control of this vehicle.Read more

This complaint is in regards to Safety Recall 272 Component Failure and Vehicle Disabling / SOS System Failure On [XXX], at approximately [XXX] PM, I was driving my Genesis vehicle during rush hour when I heard a loud popping sound. Immediately following the sound, the dashboard displayed a critical warning light stating: "Electrical Charging System Fault — Check Electrical System." Because I wa
... s actively driving in heavy rush-hour traffic, this sudden loss of charging system functionality posed an immediate safety hazard. I pressed the in-vehicle "SOS" button to contact Genesis emergency services. The operator, who identified himself as "Eddie," refused to dispatch a tow truck to assist me. Instead, he offered to read a phone number aloud for me to write down. I explained that I was actively operating a malfunctioning vehicle in heavy traffic and could not safely write down information, but he still refused to call for emergency towing. I managed to safely limp the vehicle back to my residence and subsequently arranged for the local dealership, Genesis of Las Vegas, to tow the vehicle. On Friday, June 5, 2026, the dealership confirmed that the vehicle had suffered a failure of the Integrated Charging Control Unit (ICCU), which also destroyed the 12V battery. They informed me that this failure was directly tied to NHTSA Safety Recall 272 (Integrated Charging Control Unit). While the dealership performed the ICCU remedy, they are currently refusing to release my vehicle unless I pay $500.00 for the replacement of the 12V battery. Because the 12V battery was directly damaged as a consequential result of the recalled ICCU defect, it should be covered under the safety recall remedy and vehicle warranty. As of this reporting, the dealer is holding my vehicle hostage over this fee, and Genesis Motor America has failed to resolve the issue despite a formal complaint being filed with them.

Highway Incident: While traveling at highway speeds, a sudden evasive braking maneuver caused the truck to drop power. Upon attempting to re-accelerate, the throttle pedal went to the floor with zero response, and the vehicle continued to decelerate on an active highway. Multiple trailing vehicles had to make emergency maneuvers to swerve around the decelerating truck to avoid a high-speed, rear-e
... nd collision. Subsequent Incidents: The vehicle repeatedly forces an uncommanded speed limit of 11 mph while attempting to accelerate from a complete stop or merge from stop signs. This severe lack of predictable acceleration creates an immediate risk of being T-boned or rear-ended by cross-traffic, making the vehicle entirely unsafe to operate in normal traffic conditions. An authorized Ford dealership has confirmed the underlying failure of the hybrid system. They kept the vehicle for approximately one month to replace the entire hybrid drive unit. Following that repair, the vehicle was returned to the dealer a second time, where technicians confirmed a software communication failure between the electric and gas systems, attempting to resolve it by flashing/reprogramming the ECU. The vehicle’s hybrid system and software have been extensively inspected and worked on by manufacturer-certified technicians at an authorized Ford dealership. It has not been inspected by police or insurance, as no physical collision has occurred yet. No warning lamps or messages.Read more

NHTSA COMPLAINT — SHORT VERSION I am reporting a persistent, unresolved, safety-related steering defect in my 2025 Hyundai Ioniq 6 (leased 10/12/2024). Beginning in September 2025 at approximately 15,412 miles, the vehicle exhibits: (1) uncontrolled steering wheel shifting left and right at highway speeds; (2) hard pulling to the left when accelerating or decelerating; and (3) the vehicle swayin
... g or jerking within its lane without driver input. I described the issue to the dealer as "pretty dangerous to drive" — this language is documented in Repair Order #XXX. Despite 6+ documented repair attempts over 9 service visits from September 2025 through May 2026, the defect remains unresolved. Repairs attempted include: two 4-wheel alignments, road-force balancing, steering angle sensor calibration, front camera calibration, new front view camera installation, and a complete steering gear box (R-MDPS) replacement. The vehicle was out of service for 129 documented days. CRITICAL ADMISSION: Dealer Repair Order #XXX(11/5/2025) explicitly states that Hyundai's Technical Service Bulletin procedures for this steering defect only apply at speeds of 40 MPH and below, and that "above that speed there are too many variables." The defect occurs at highway speeds above 40 MPH. This is a written admission that no manufacturer-approved repair procedure exists for the defect as experienced. Hyundai Techline Case #XXX was opened in January 2026. After Techline involvement and new camera installation, the technician's own repair order states "concern still present" after road testing. Hyundai Motor America corporate case #XXX was opened, and Hyundai has now stated they cannot process a buyback or lemon case.

The dealership documented the following diagnostic trouble codes: P075B, P0741, and P2757. These codes are listed together in Toyota's o
... wn C-HR service manual as indicators of Torque Converter Clutch Circuit failure within the CVT system, confirming internal mechanical failure of the transmission. These are not minor or maintenance-related codes — they indicate a fundamental failure of the CVT's internal components. This is a known, widespread defect affecting 2018–2020 Toyota C-HR vehicles. Hundreds of owners have reported identical CVT bearing failures, often with no warning lights or prior symptoms, at mileages ranging from 38,000 to 140,000 miles. Toyota has acknowledged CVT issues on this model previously — issuing a software service campaign (Special Service Campaign J0D) for CVT programming defects — yet has refused to issue a recall or extended warranty for the underlying mechanical bearing failures now presenting across the fleet. Notably, Toyota Canada has extended warranty coverage for identical CVT failures on the same model years, while Toyota USA has declined to offer comparable relief to American owners facing the same defect. This defect represents a significant safety hazard, as CVT failure can result in sudden loss of propulsion while driving at highway speeds. Requested Action: Formal NHTSA investigation into CVT transmission bearing failures in 2018–2020 Toyota C-HR vehicles, and consideration of a recall or extended warranty campaign consistent with what Toyota Canada has already provided.Read more

I am writing to formally report a critical safety defect in the vehicle’s transmission system. While driving, the vehicle began experiencing severe vibrations, accompanied by an abnormal increase in engine RPMs, while the vehicle failed to accelerate appropriately. The vehicle became unresponsive, limiting my speed to 15-20 mph. This forced me to make frequent stops every 6-7 minutes to allow th
... e transmission to cool down, as the car would not sustain normal speeds. This failure created an extremely dangerous situation on the highway. Due to the sudden loss of power and inability to maintain traffic flow, I was subjected to aggressive behavior from other drivers, who were honking, gesturing, and clearly endangered by my inability to accelerate. This transmission failure is a major safety hazard that renders the vehicle unreliable and dangerous to operate in any traffic condition. I am requesting an immediate investigation into this transmission defect and a permanent resolution from General Motors, as this issue poses a significant risk of causing a collision. I spoke with the owner of AAMCO, and he showed me that they have 7 of these Chevy Suburbans, GMC Yukons, and Chevy Tahoes, Escalades, and they all have the same problem, the transmission needs to be replaced, and General Motors is not notifying car owners about this problem, but it should.Read more

The turbo went completely out at around 105k miles while I was driving to work. I had to coast into a repair shop because it was smoking and wouldn’t go over 20mph and then have it towed to the place that repaired it. Since then, the transmission is having trouble shifting gears. The car struggles to accelerate and I have to go abnormally slow after coming to a complete stop in order for the car
... to get into gear. The onstar diagnostic says everything is fine but it is clearly not fine.Read more

The transmission was shifting extremely rough. When attempting to accelerate from a stop, the RPMs would increase without shifting for several seconds causing me to be stuck in the middle of intersections. It would also slip from a higher gear to a lower gear for no reason. This included while driving on the interstate causing a sudden loss of speed. A local transmission shop confirmed the issue a

This is my daughters vehicle. She was driving home from work with my [XXX] and [XXX] grandchildren in the car. The car suddenly wouldn't drive at a safe speed and was chugging along. She almost got into an accident because she couldn't go faster than about 12 mph. She as finally able to pull over in a safe location and called AAA. My son in law met her and picked her and the children up. The vehic

Water then runs down and burned out the ECR module that is located beneath the drivers side foot well. Volvo is aware of the problem and is currently checking all vehicles for the blocked drains. They were given a 5000.00 estimate for repairs. Today VOLVO refused to repair it at their expense. There should be a full recall on this issue. I am a Fire/Explosion Investigator who has investigated numerous car fires related to Control modules catching fire. This could have caused a fire and trapped my grandchildren in the rear seat. The dealership reported 2 other vehicles in for the same issue.

I am reporting a potential premature transmission failure in my 2019 Toyota Highlander AWD. At approximately 89,000 miles, the vehicle developed a noticeable and persistent whining noise coming from the transmission/drivetrain area. The noise continued despite transmission service and has progressed to the point where the vehicle requires a transmission replacement. I have had the vehicle evaluat
... ed by three separate repair facilities, including transmission specialists. All three independently determined that the transmission has failed and requires replacement. Repair estimates range from approximately $7,200 to $12,000. A complete transmission failure at approximately 89,000 miles is unexpected and raises concerns about a possible design or manufacturing defect. A transmission failure while driving could cause loss of power, inability to accelerate, reduced control of the vehicle, or create a dangerous situation while merging, entering traffic, or traveling at highway speeds. The vehicle has been maintained and used normally. I am submitting this complaint because I believe this issue may affect other Toyota Highlander owners and should be investigated for a potential safety-related defect.Read more
