Over the last approximately 20,000 miles or so I've noticed a studder/shaking of the vehicle when turning and/or accelerating at slow speeds, in particular, while the car is cold (not warmed up). I change the transfer case fluid about 5,000 miles ago and the problem did not resolve. I now see that there is a class action lawsuit against BMW for known failure of the transfer case. I would like m

SYSTEMS AFFECTED: Electrical System (12V Power Supply / Low-Voltage), Climate Control (HVAC System / Thermal Management), Towing / Recovery DESCRIPTION OF SAFETY HAZARD & DEFECT: My 2022 Rivian R1T experienced a sudden, complete electrical failure due to a defective HVAC system, resulting in a dangerous hard-bricked state that rendered the vehicle totally inoperable. Approximately 30 days prior to
... the incident, the vehicle underwent a comprehensive inspection at a Rivian Service Center where both the HVAC system and 12-volt battery system were tested and cleared. Shortly after, a primary internal failure/glitch within the HVAC equipment created a high parasitic power draw on the vehicle's low-voltage circuit while parked. The HVAC module failed to enter sleep mode, continuously draining the dual 12-volt AGM battery array below critical operating thresholds. This rapid, deep-discharge condition completely disabled the vehicle's primary high-voltage contactors and low-voltage control modules, locking out all vehicle functions, electronic doors, and drive controls. The vehicle could not be restarted, jump-started normally, or safely shifted into neutral, necessitating an emergency flatbed tow to the service center. Technicians confirmed that the primary HVAC equipment failure directly caused the full depletion and destruction of the 12-volt electrical system. This defect presents an immediate safety risk. An uncommanded HVAC-induced power drain that completely depletes the 12-volt system can cause sudden electrical failure, vehicle bricking, loss of hazard lights, and lock-out conditions, potentially stranded occupants in dangerous environments or busy roadways. Rivian is treating this catastrophic multi-system failure as non-warranty maintenance, refusing to address a clear pre-existing latent defect in their low-voltage power management and thermal architecture. REQUESTED ACTION: Investigation into 2022 Rivian R1 HVAC power management defects causing severe 12V drainRead more

All dash warning indicators come on randomly and a code reader indicates fuel injector issue. That was checked and is not the issue. This is a well-known symptom in this model year that head gasket leaks caused by under-specified head bolts do not keep the cylinder head sealed properly and this leads to many other issues.

Oh wow I don't even know where to start. The second I came home with the car for $32,995 off the used dealership it was a horrific disaster. I have replaced the rear fuse panel 2x already(water damage). The amp was fried from water damanage. The ambient lights and screen along with the gear lights only sometimes work. My morimoto aftermarket headlights wiring all have completely melted and needed
... to be replaced and that is just the small things. The car has always had severe driving malfunctions. These include: Jerking when putting into gear (any gear), shudders, it will rev up when i am braking, usuallu after a small hill or bump it will get really loud like it is in a much higher gear, it looses power and goes into random limp mode, the car has recently died in mid drive just completely lost acceleration power until it died. It will start right back up, but then same thing. Now when driving it will slightly jerk and steer to the side ever 3 seconds. Enough for me to hold the steering wheel tight. These are a few of the codes it reads, although some codes come and go, but these remain on: P12E7, P12EC, P12F4, P12F9, P0121, P0171, P0161, P0131, P069E, B097B, B1395, B1516, B1517, B260E, B260E, B2615, B2745, U0800, U1808, U0109, U007C. nOW MY BIGGEST PROBLEM IS THE CAR IS SO BAD IT IS NOT DRIVABLE AND NO ONE CAN TELL ME THE PROBLEM. IT VIOLENTLY JERKS WHEN TURNING AS IF SOMEONE HIT ME FROM BEHIND GOING 50MPH. iT USUALLY DOES IT WHEN I TURN THE WHEELS SLOWLY LIKE ON TURNS, BUT IT ALSO DOES IT WHEN STOPPING AT A RED LIGHT AND THE LIGHT TURNS GREEN IT JUST BOOOOOOM. iT IS SO LOUD AND AND SO VIOLENT IT IS AS IF MY BACK END FELL OFF. aLSO THE TIRES ARE LOCKED UP AND WHEN I TURN IT MAKES MY TIRE SCREAM. THESE PROBLEMS HAVE BEEN GOING ON SINCE I PURCHASED THE VEHICLE AND GOT IT HOME AROUND 70K MILES AND NOW I AM AT 160K WITH THE SAME PROBLEMS AND THEN SOME. The car twice now has driven itself when in park with car running. I put in park and was on phone at store and it droveRead more

I brought my car to my mechanic for a routine oil change and the drain plug on the oil pain failed. It is made with plastic and melted due to exposure to high engine heat rendering it useless and requiring the oil pan and drain to be replaced. When we called Nissan they said this is a known issue with several Nissan models and they have since had to retrofit a part to correct the malfunction. Had
... this plug failed while I was driving it could have caused massive engine failure. There were no indications there was anything wrong with my oil pan and this mechanic has done my oil changes on several cars for over 10 years. Despite the associate at the Nissan dealership we got the replacement part from acknowledging this is a known issue, no service campaign has been issued. I called Consumer affairs to discuss next steps in order to get this covered under warranty and was told to call back with my invoice information to submit for reimbursement. Upon calling back I was told they will not cover the repair as it was done at an independent mechanic which I was not informed of on my previous call. They assured me a supervisor would call me back by the end of the following day and I have not received a call from anyone. Failure for Nissan to take responsibility for a manufacturing defect is now leading to potential safety hazards and undue financial responsibility on its consumer's behalf since their employees are improperly trained. I will never purchase a Nissan again and can guarantee I will share this poor experience with everyone I know.Read more

I own a 2022 BMW X5 xDrive45e that has developed a drivetrain shudder during slow-speed, tight turns while lightly accelerating, such as when maneuvering in parking lots or making U-turns. The vibration is consistently reproducible under these conditions and is felt through the vehicle during the turn. The vehicle otherwise drives normally at higher speeds. After researching the issue, I found th
... at many other owners have reported substantially similar symptoms involving the transfer case on BMW xDrive vehicles. My independent BMW repair shop has recommended a transfer case fluid service as the first corrective action based on the known nature of this problem. I am having that service performed and will retain all repair documentation. I am submitting this complaint because this appears to be a recurring issue affecting multiple vehicles. If the condition worsens, it could lead to drivetrain binding during low-speed maneuvers and may affect safe vehicle operation. I request that NHTSA investigate whether this is a broader defect requiring manufacturer action. I will update this complaint if the repair does not resolve the condition or if additional diagnosis identifies an internal transfer case failure.Read more

Because of the intentional failure of GMC and there promise of “We are Professional Grade”, I almost got plowed down by a semi when the car began to quit on the highway going 60. After pulling into the next driveway, which happened to be a Parker’s Kitchen, and ending up on the curb spot, thanking God I wasn’t dead, I sat there for a moment wondering what just happened. As I went to restar
... t the car, it wasn’t having any of it. 40,000 miles, not professional grade GMC, circus grade. Towed it to my home, figuring it has to be something minor and a diy fix. Bought the hyper-tough code reader delivered by Walmart and it delivered professional grade results: U18A2, P1787 and P187E. I am beyond pissed. I could have died due to your intentional negligence in manufacturing. I have a car that will not start, with payments. I have searched the internet and found your “save ourselves plan” and let’s do a voluntary recall starting with 2021 on the same failed parts I am dealing with at the moment. Thanks GMC, who is the ringleader of your circus?Read more

While in the middle of traffic, the driver contacted a family member for assistance and the vehicle was towed to the driver's residence. On the following day, January 6, 2026, the vehicle was towed to a service center for inspection. It is unknown if the warning messages observed January 6, 2026 were due to the vehicle being towed. At the service center, a tire was replaced and the brake system was flushed, at the owner's expense. Afterward, the driver continued to operate the vehicle. As of August 5, 2026, this incident had not recurred.Read more

I am reporting a recurring safety-related issue with my 2024 Mazda CX-90 Turbo S Premium involving the mild hybrid system. The first failure occurred at approximately 28,000 miles. While driving, the vehicle displayed multiple warning messages, including "Mild Hybrid Battery Malfunction," "i-Stop Malfunction," and "Engine Malfunction." Shortly afterward, the vehicle entered a reduced-power (limp
... mode) condition. The loss of normal power made it difficult to safely accelerate and keep pace with surrounding traffic, creating a significant safety concern. The dealership diagnosed the vehicle and replaced the mild hybrid battery. My vehicle remained out of service for approximately one month while repairs were completed. At approximately 56,000–58,000 miles, the same problem occurred again. The vehicle once again displayed the "Mild Hybrid Battery Malfunction," "i-Stop Malfunction," and "Engine Malfunction" warning messages and again entered reduced-power mode while driving. The repeated loss of power created another serious safety concern because the vehicle could not accelerate normally when merging into traffic or driving on higher-speed roads. After diagnosing the second failure, the dealership informed me that, in addition to replacing the mild hybrid battery, corrosion had been found in the wiring harness and internal wiring associated with the hybrid battery system. Those components also required replacement. Due to parts availability, my vehicle remained at the dealership for an extended period before repairs could be completed. This vehicle has experienced the same hybrid system failure twice within approximately 58,000 miles, despite the first battery having already been replaced. I am concerned that this is a recurring defect affecting the mild hybrid electrical system. A failure that causes multiple system malfunction warnings and forces the vehicle into reduced-power mode while driving increases the risk of a crash, especially when merging onto highwaysRead more

The 10-speed transmission exhibits severe and dangerous shifting behaviors. It frequently shudders and jerks extremely hard when shifting between gears.Most critically, the transmission fails to properly engage into gear. While driving, I came to a complete stop at a red light in active traffic. When the light turned green and I attempted to accelerate, the transmission would not engage into gear,
... leaving the vehicle completely immobilized and just sitting there in the middle of traffic. Because the truck failed to take off and move forward, it created an immediate road hazard and almost caused me to be severely rear-ended by the traffic behind me.This transmission hesitation and failure to engage poses an immediate and severe safety risk of a high-speed collision.Read more

MGU Failed, 48v code P0DAF had early signs of premature failure. when on the highway, vehicle shut off completely, no power what so ever. Couldn't steer correctly and vehicle was going highway speeds (approximately 70mph) dealer has confirmed the issue being there MGU gone bad, but I have records of water intrusion multiple times on the rear seats, headliner & back glass (XL1) and water intrusion
... can cause BPCM to go bad along with the MGU to go bad. they first appeared on or around December 2025, most likely way before that but just never noticed it. check engine light came on and showed a code for the BPCM going bad and then I had the CHMSL replaced 3 times under warranty & then the 4th visit they did they urethane warranty superseded the XL1 and even after that fix, there water leak still occurred and dealership wouldn't fix it they stated Stellantis denied the back glass replacement and further repairs because im out of warranty but the warranty expires 8 Years/150,000 miles and my vehicle is only 6 years old and sitting at 118,350 miles. but the entire problem with water intrusion most likely started anywhere from 60-70,000 miles ago. even when I purchased the vehicle at 39,801 miles I noticed the water stains on the headliner but was advised the CHMSL caused that so it was fixed so technically the CHMSL was replaced roughly 4 times along with the original making it a total of 5 CHSML. so my issue is that its highly possible that the water intrusion that was never fixed for thousands of miles and many months leaked into the rear seats near the 48V Battery pack and eventually started shorting and lead to the MGU going bad. so this all could've been avoided if dealership fixed the water leak many many visits ago. along with the MGU could've been replaced under the major emissions comp warranty way. before that ever expired when it showed signs of premature wear like DTC codes popping up at 100,000 miles and even many more visits prior to December.Read more

Ever since I bought this truck new, I noticed a lot of metal shavings and debris in the oil filter every single time I changed the oil. I took it to the dealership multiple times to have this looked into before the engine recall came out. The dealership took pictures of the metal and sent them to a General Motors engineer, but the engineer just told them it was "normal." Later on, the truck went i

Then on August 4, 2026, I was driving on a crowded expressway right through a construction zone with absolutely no shoulder to pull over on. Out of nowhere, the truck started hesitating badly, lost power, and the engine started making a really loud knocking noise. It was barely running, and it was incredibly dangerous because there was nowhere to go and traffic was heavy. Luckily, I was able to limp the truck along just far enough to clear the construction zone and pull over safely.Read more

ISSUE 1 – UNINTENDED DECELERATION (Power Train): While driving at highway speeds (60–80 mph) with foot off accelerator for approximately 5+ seconds while coasting, the vehicle unexpectedly executes a sharp, single downshift causing sudden unintended deceleration and an RPM spike. No warning lights illuminate. Documented on 11 occasions between May 20, 2026 and July 29, 2026; incidents occurred
... prior to May 2026 but were undocumented. Occurs most frequently decelerating off highway exit ramps but also during general highway coasting in Houston, TX. A passenger was present during multiple incidents. Trailing vehicles are not anticipating the sudden speed reduction, creating rear-end collision risk. ISSUE 2 – FALSE BLIND SPOT / REAR RADAR ALERTS (ADAS): The Blind Spot Monitoring and Rear Radar Sensor systems generate daily false alerts — both audible and visual — when no vehicles or objects are present. Triggers randomly across varying conditions. False alerts have caused multiple aborted lane changes that were otherwise safe to execute. ISSUE 3 – LANE KEEPING ASSISTANCE (ADAS): The LKA system applies forceful steering corrections during intentional, signal-indicated lane changes, including in areas without lane markings. Occurs at highway speeds during on/off-ramp transitions. Corrections have triggered reactive maneuvers by surrounding drivers in dense traffic, causing near-collision situations. Dealer service appointment scheduled August 6, 2026.Read more

I own a 2022 Chevrolet Silverado 2500HD equipped with the 6.6L Duramax diesel engine and Allison-branded 10 speed (10L1000) automatic transmission. VIN: [XXX]. While pulling away from a traffic light and accelerating to approximately 20 to 30 mph, the transmission suddenly began shifting harshly and erratically, experienced delayed engagement, unexpectedly downshifted, and would not shift into ov
... erdrive. At the same time, the check engine light illuminated and a Reduced Engine Power warning appeared. There were no warning lights, messages, or transmission symptoms prior to this incident. I pulled into a parking lot for approximately one hour, but when I resumed driving, the same failure occurred again. The transmission malfunction created a safety concern because the vehicle unexpectedly lost normal shifting and power while operating in traffic, making it difficult to accelerate and maintain speed safely. I contacted OnStar, which reported both an engine and transmission fault. I then drove the vehicle to my independent diesel mechanic, who diagnosed a failure of the transmission control valve body caused by an internal solenoid that is not serviceable separately, requiring replacement of the complete transmission control valve body assembly. The repair has been completed, so the original failed component is no longer available for inspection. The failure was confirmed by an independent service center. The vehicle has not been inspected by Chevrolet, law enforcement, or an insurance representative. I contacted General Motors to determine whether my VIN was included in the existing transmission control valve recall and was advised that it is not. I am submitting this complaint because my truck experienced the same symptoms and the same component failure as vehicles covered by the recall, despite my VIN not being included.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle suffers from an intermittent, total engine stalling and propulsion failure. Without warning, the engine completely shuts down while driving and automatically drops the vehicle into "Accessory (ACC) Mode". The vehicle is fully intact, operational when it restarts, and is available for imm
... ediate inspection upon request How was your safety or the safety of others put at risk? This issue has occurred five total times in live traffic, severely risking the safety of the vehicle's occupants and surrounding drivers. The most recent and dangerous incident occurred on the freeway in heavy, stop-and-go traffic. A sudden, complete loss of power on a high-speed freeway leaves the vehicle entirely vulnerable to rear-end collisions, as it leaves no room or momentum to safely coast to the shoulder. Has the problem been reproduced or confirmed by a dealer or independent service center? No. The vehicle has been brought to an authorized Hyundai dealership five separate times specifically to diagnose this exact stalling issue. Because the failure is intermittent, dealership service technicians have been unable to replicate the problem during their test drives or resolve the root cause. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?

The car would do this regularly until I found out subaru had a fix for the transmission software. I recently had to pay to have this done even though my car was still within the powertrain warranty because Subar

I am reporting what I believe is a safety‑related defect involving the automatic transmission in my 2022 Land Rover Discovery Sport, VIN [XXX]. Approximately five months after the factory warranty expired, at around 44,000 miles, the transmission began slipping unexpectedly, and the vehicle would not accelerate above roughly 25–35 mph. This occurred while driving, creating an unsafe condition
... . I needed to make a left turn across traffic, but because the vehicle would not accelerate properly and could not safely match the speed of other vehicles, I judged it too dangerous to change lanes and complete the left turn. Instead, I had to make a right turn, pull into a driveway, turn around, and continue straight to avoid an unsafe lane change. A vehicle that cannot respond normally to throttle input presents a risk when merging, changing lanes, or crossing intersections. The symptoms are transmission slipping under acceleration, limited maximum speed, and abnormal drivability. To my knowledge, this is not due to driver error or poor maintenance. The problem has been reproduced and observed by an authorized Land Rover dealer (Land Rover of Alexandria, Alexandria, VA), which provided an estimated repair cost of about $7,000, indicating a major transmission or control‑system fault. The vehicle and transmission are available for inspection upon request. I understand there have been prior recalls and technical bulletins involving Land Rover transmission control issues (including a recall where certain Discovery Sport and Range Rover Evoque vehicles could unexpectedly shift into neutral due to sensor and software calibration problems). My vehicle’s behavior—loss of proper drive, slipping, and limited speed—raises similar safety concerns even if the failure mode is not identical. I am concerned that there may be ongoing transmission control or calibration issues that could affect safety.

From when we purchased this car new until the day we traded it. There were many times on the freeway at 60-65 MPH that you would need to move over a couple of lanes and went to wide open throttle and the car would simply do nothing for 1 to 2 seconds.
