On multiple occasions at startup, vehicle made unusual sounds then either stalled shortly after starting or simply wouldn’t start. Vehicle has also stalled multiple times at red lights and stop signs. On these occasions nearly the entire dashboard lit up simultaneously with warning lights across many unrelated systems (“Christmas tree” effect), not a single isolated fault, often while on int
... erstate at 70mph. Recurring, not one-time. 1.ELECTRICAL/ABS: Aug 2025, right front ABS wheel speed sensor replaced after dash lights loss + reported dying after startup; dealer couldn’t duplicate stalling. As of Aug 2026, scan shows left front ABS sensor faulting (open/short to ground, implausible signal) plus parking brake module fault referencing wheel speed sensor implausibility. Dealer also flagged left rear ABS sensor as Critical. Numerous low-voltage faults present across modules simultaneously (supply voltage too low, data bus implausible, control module input power low), matching dashboard cascade events. Battery replaced May 2024 after failing load test. 2.ENGINE: Dec 2024, cylinder 6 injector replaced (complete goodwill, dealer+VW corporate) for CEL/air-fuel imbalance. CEL returned next month for same fault; escalated to full cylinder head replacement ($6,054.95). 3.STEERING: Dealer inspection Aug 2026 flagged steering rack and pinion as Critical ($2,093.19), req. 4-wheel alignment. Confirmed with NHTSA/VW this vehicle is NOT subject to steering knuckle recall 21V026000/40Q7 — separate, non-recall defect. Requesting NHTSA review this combined pattern of stalling/no-start, cascading electrical faults, and critical steering failure.Read more

I was driving and during the drive I realized that if the accelerator pedal was pressed more than the lightest touch the car would stop accelerating. I decided that I had to turn back to go home, and during my return trip the engine oil pressure lamp started flashing at me. Soon after, I entered a roundabout and pressed the clutch. At this moment the engine stopped working (tach to 0 rpm) and I ha

Prior to that day, it seemed like the car was having trouble with its turbocharger--boost was delayed at first and later intermittent. Since I was on a mostly empty road this did not pose a safety threat to others, though I did slow down traffic as I pulled over on a two-lane road. If this same issue had happened later into my drive on a busier road or highway, mine and others' safety would have been put at risk due to my car suddenly not working with little warning. The engine is seized and needs to be replaced. It would be available for inspection as I have not yet replaced it. The current cost to repair has been quoted to me at between $9000 and $10000.Read more

My 2016 Ford Edge with the 2.0L EcoBoost engine began having rough starts, misfiring, and an intermittent check-engine light. The warning light repeatedly turns on and off, but the problem continues. On 96000, the Ford dealership diagnosed internal coolant intrusion into the engine/cylinder area and advised that the vehicle requires major engine repair or replacement estimated at approximately $10
... ,000. This defect can cause continued misfires, reduced engine performance, overheating, stalling, or sudden loss of power while driving. I am concerned that the engine could fail or lose power in traffic without adequate warning. This appears to be a premature internal engine failure rather than normal maintenance. Ford declined my request for financial or goodwill assistance even though coolant intrusion is a documented problem affecting similar Ford EcoBoost engines. I am requesting that NHTSA investigate this defect and determine whether a safety recall is necessary.Read more

On January 26, 2026, my 2019 Hyundai Sonata SEL suddenly became inoperable overnight. The vehicle had been operating normally with no warning signs—no check-engine or oil-pressure light, abnormal engine noise, overheating, loss of power, or other indication of an impending failure. The following morning, the engine would not start. The vehicle was towed to an independent mechanic on January 28,
... 2026, who determined that the engine was locked/seized. On February 11, 2026, it was towed to Wayne Hyundai for further diagnosis. The vehicle had only 51,533 miles and had received Hyundai’s Knock Sensor Detection System (KSDS) update. Hyundai denied warranty coverage, citing engine sludge, despite my providing a complete service history after resubmiting the missing receipts I had previously misplaced. My primary concern is safety, not the warranty dispute. A sudden engine seizure without warning could cause an unexpected loss of propulsion or create a dangerous situation if the engine fails while the vehicle is being driven. This concerns me because Hyundai Theta II engines have previously been associated with engine seizure and stalling, including issues addressed through The Hyundai Theta II Engine Settlement: and subsequent litigation involving certain 2019 Sonata vehicles. I respectfully request that NHTSA investigate whether a continuing or insufficiently addressed engine defect exists in affected 2019 Hyundai Sonata vehicles, particularly sudden engine seizure/no-start failures occurring without warning. I also ask NHTSA to examine whether existing recalls, campaigns, software updates, warranty extensions, and other remedies adequately protect owners when an engine fails suddenly before the KSDS system provides a warning.Read more

Vehicle: 2022 Hyundai Palisade, approximately 78,000 miles. The vehicle has experienced a recurring engine/powertrain malfunction involving engine stalling, hesitation/rough operation, startup rattling, cylinder air/fuel imbalance, and misfires. The exact failed component is currently UNKNOWN. The vehicle is available for inspection upon request. The vehicle has stalled at low speeds, creating a
... safety concern because the engine can unexpectedly shut off or lose power while the vehicle is being operated in traffic. Unexpected stalling could leave the vehicle without normal acceleration when entering or crossing traffic and creates a risk of a collision involving the occupants or other motorists.The vehicle has been evaluated and serviced by a Hyundai dealership for engine-related concerns. Diagnostic trouble codes associated with these problems have included P000C, P219D, P219F, P21A0, and P0302. Of particular concern, P219D, indicating a Cylinder 2 air/fuel ratio imbalance, has occurred repeatedly, and the vehicle subsequently generated P0302, indicating a Cylinder 2 misfire. This suggests a recurring problem involving the same cylinder, although the underlying cause remains UNKNOWN.Previous repair efforts have included work involving the vehicle's VVT system, but the engine-related problems and diagnostic codes have continued/recurred. The vehicle/component has been inspected by a Hyundai dealership. To my knowledge, it has not been separately inspected by police, insurance representatives, or NHTSA. Whether Hyundai corporate/manufacturer representatives have directly inspected the vehicle is UNKNOWN.Prior to and during these incidents, symptoms included the check-engine warning light, startup rattling/noise, engine hesitation/rough operation, and stalling at low speeds. Diagnostic codes were stored when the check-engine light appeared. The problems have occurred on more than 100 occasion rather than being a single isolated incident.Read more

I am filing this complaint regarding a severe safety hazard and prolonged failure to resolve an official recall repair by the manufacturer and dealership. In April 2026, the vehicle was brought to the dealership for an official recall repair. The repair was delayed for 2 months. In June 2026, after the dealership confirmed completion, I retrieved the vehicle. While driving on the highway, the che
... ck engine light suddenly illuminated and the vehicle completely lost power. Pressing the accelerator pedal produced no response, leaving the car unable to accelerate in active high-speed traffic. This created an extreme safety risk that nearly caused a severe highway collision. The vehicle was towed back to the dealership. The dealership returned the vehicle a second time, claiming it was repaired, but the exact same check engine light illuminated immediately with the same loss of power, requiring another tow. As of August 2026, the dealership has retained the vehicle for over 4 months in total due to backordered parts, without providing a clear completion date or loaner/rental transportation support. The dealership and corporate customer care are currently ignoring attempts to communicate. The recurring loss of engine power on the highway and unresolved recall defect pose a direct and imminent risk to public road safety.

I am reporting a serious recurring safety concern involving a 2017 Ford Fusion SE with a 1.5L EcoBoost engine. The vehicle was purchased used in August 2022 with approximately 50,000 miles. Within months, significant coolant and engine problems began. In February 2023, at approximately 55,940 miles, the vehicle developed a coolant leak. A pressure test confirmed the water pump was leaking and it
... was replaced. At approximately 84,189 miles, the vehicle experienced white/gray exhaust smoke, coolant loss, very low oil, and rough-running symptoms. The servicing Ford dealership referenced Ford Technical Service Bulletin (TSB) 22-2322 in connection with the diagnosis and ultimately replaced the engine short block. Despite this major engine repair, the problems continued. The vehicle subsequently experienced additional smoking, hesitation and loss of power and required replacement of the turbocharger. The vehicle was returned again because it continued to smoke and required additional repairs. I am concerned this is a recurring engine defect rather than normal wear and tear. The repeated engine/coolant failures, smoking, hesitation and loss of power create a serious safety concern because the vehicle may unexpectedly lose power or experience engine failure while being driven. Ford has been notified of the repeated failures but declined further relief based primarily on the vehicle's current age, mileage and expired warranty. This ignores that the problems began years earlier at substantially lower mileage and that major repairs failed to permanently correct the condition. I request that NHTSA investigate whether the 1.5L EcoBoost engine in this and similarly equipped Ford vehicles has a safety-related defect involving coolant intrusion, engine failure and loss of power. The vehicle is currently at approximately 101,000 miles, but the documented problems began at 55,940 miles and continued despite major repairs.Read more

Incident date: Aug 12, 2026
2018 Kia Sportage (78,051 miles). Vehicle is part of the Kia Engine Class Action Settlement due to severe internal engine defects. The engine suffers from catastrophic oil consumption, running almost completely dry three times in less than six months with no external leaks, meaning it is internally burning motor oil at a dangerous rate.This known engine defect caused severe consequential damage to
... the exhaust and emissions systems. On Aug 12, 2026, a Kia dealer technician diagnosed active code P0420. The technician's video inspection stated both the catalytic converter and O2 sensors are completely "out of specification." This double failure is a direct result of the engine defect blowing excessive liquid motor oil out of the engine block and down the exhaust pipe, fouling the sensors and melting the internal catalyst.This failure happened immediately after receiving the mandatory Kia Recall SC340 update (Catalyst Overheating Protection). The vehicle is under the 80,000-mile Federal Emissions threshold, but Kia is denying coverage based strictly on a calendar time limit. They refuse to take responsibility for emissions components destroyed by their settlement-recognized engine defect.This condition poses a serious safety hazard. Driving with heavily fouled O2 sensors and a failing catalytic converter causes poor engine performance, unpredictable stalling or hesitation during acceleration, and excessive unburned fuel vapors to enter the environment and potentially the cabin. I request the NHTSA investigate Kia’s refusal to cover secondary emissions damages directly triggered by their defective oil-burning engines.Read more

I am reporting a premature oil pump failure on my 2020 BMW M340i xDrive with 42 thousand miles. The vehicle has been well maintained and has not experienced any oil pressure warning lights. However, the electronic engine oil level measurement repeatedly fails to complete once the engine is fully warmed up. I have also received stored BMW fault code 21B2C7 relating to engine oil pressure plausibi
... lity/excessive oil pressure. The fault currently shows as inactive, but it was not present previously. I have monitored engine oil pressure using diagnostic software. Pressure is generally around 38–42 psi at hot idle, approximately 44–48 psi during cruising, and can rise into the 60–78 psi range during acceleration. Although these readings are generally stable, the combination of the stored pressure plausibility fault and repeated inability to measure the engine oil level is concerning. I have also noticed a whining/humming noise from the front of the engine at low RPM, particularly during stop-and-go driving and while decelerating in first and second gear. There are numerous owner reports involving premature oil pump failures on BMW vehicles equipped with this generation of the B58 engine. The original oil pump used on earlier vehicles reportedly contains plastic internal components that can deteriorate over time and heat exposure. BMW later revised the oil pump design. BMW Korea has also reportedly begun providing repairs for certain B58 oil pump failures outside the normal warranty period while the issue is being investigated in that market. An engine oil pump is a critical lubrication component and is not a normal maintenance or wear item. Failure of the pump could result in insufficient or excessive oil pressure, loss of lubrication, severe engine damage, engine seizure, or loss of power while driving. I am submitting this complaint so NHTSA is aware of the potential pattern of premature oil pump failures affecting 2020 BMW M340i vehicles andRead more

... t. They said if I did not replace it, it would eventually damage other parts of the engine. After talking with other Mini owners, I found out it is common for this part to fail much sooner than it should. They all felt it should be recalled, particularly due to the repair cost and short lifespan. I spoke with Mini/BMW, and was told that it was a "wear and tear" item, and they took age into consideration, so they could not help me.Read more

While driving, multiple dashboard warning lights suddenly illuminated simultaneously (including the Check Engine light, Emissions system warning, and various safety sensor alerts). The vehicle experienced a sudden loss of engine power, rough idling, and hesitation upon acceleration, which created an immediate traffic hazard. I took the vehicle to an authorized Honda dealership service center. The
... diagnostic scan revealed a failure of the fuel injectors (with diagnostic trouble codes indicating a system too rich and cylinder misfires). The dealership service advisor informed me that this premature fuel injector failure is a highly common and widespread systemic defect with Honda’s 1.5L Turbo direct-injection engines, stating that their shop actively stocks these parts because they perform at least one of these replacements every week. This premature component failure at low mileage (54,000 miles) is a severe safety risk that causes unexpected engine stalling or power loss while driving.Read more

Engine piston recall defect. Car has been at the dealership 12 days today and has been diagnosed and has been submitted to a Kia corporate case for repair free of charge. Car had no warning lights on and basically blew up on me driving home from my overnight work shift Thursday into Friday, July 31 morning. Every day they tell me they will give me a loaner and every day they lie. I have called unt
... il I’m blue in the face and no action has happened. I’m making a report because I’m about to lose my home and the car in the shop being repaired both because I’m stranded at my house as a single woman with a child with no alternate transportation. It is at the Kia dealership in Southhaven Mississippi 745 East Goodman Rd. I maintained this vehicle and paid every single note on time and did nothing wrong. I’m gonna lose everything because of this recall repair needed that I never knew anything about. It wasn’t on my auto report in 2024 when I bought the car somehow or I probably wouldn’t have bought it with any engine issues but I was unaware. The car literally never had any lights on or issues until the morning when it blew up. During this time I thought I was supposed to get alternate transportation and that hasn’t happened. Because I invested in Kia I’m the only one suffering right now about to lose my home and job because they have my car and won’t give me alternate transportation. A free repair is no good if you’re going to lose everything you work hard to maintain while it’s being repaired. I will never buy Kia again and I will never tell anyone else to buy. Absolute horrible experience so far. I’ve already paid out-of-pocket for a tow which can’t be reimbursed until 6 to 8 weeks after the repair is complete from what I read. If I end up homeless over this 6 year old car I thought would last me, I’m not gonna want the car anymore.Read more

SLUDGE IN ENGINE- UNDER 100,000 MILES We had been keeping up with all recommended services, and it is cosmetically perfect, but the car is now a total loss. A Check Engine light came on, and we began to notice a tremor/shake and took it to Southern Team Nissan. The Nissan dealer diagnosed sludge in the engine and said it would need a total engine replacement. The Nissan dealer advised that the cos
... t of that would be more than the car was worth. After they pulled the pan to check if there was definitely sludge, the car then shook so badly that it felt unsafe to drive. Research shows that this is a known issue, with many cases of documented VQ35DD sludge problems. We see many listed cases on this website under complaints for 2017 Nissan Pathfinders.Read more

I am filing a safety complaint regarding my 2012 Kia Rio, which currently has approximately 150,000 miles. I first became aware of these problems at approximately 120,000 miles. The vehicle has excessive oil consumption despite being consistently and properly maintained. I have been meticulous about maintenance because the vehicle has a lifetime powertrain warranty, and I have documentation and r
... eceipts for required maintenance, including regular oil changes and other scheduled services. On multiple occasions, I have taken the vehicle in for a scheduled oil change and discovered that it had little or no oil remaining. Because of this, I have had to begin having oil added between regularly scheduled oil changes. I do not know the exact amount of oil being consumed because I initially had no reason to monitor or measure oil consumption between oil changes. The vehicle also has a recurring catalytic-converter/check-engine warning that comes on, goes off, and later returns. It has experienced noticeable loss of power and has developed a clicking or knocking sound from the engine. When the vehicle is sitting or idling, it can also indicate that it is running hot even though it does not appear to actually be overheating. These problems have continued despite regular, documented maintenance. I am concerned about the safety implications of a vehicle consuming enough oil to have little or no oil remaining before its next scheduled oil change, particularly when there may be no consistent warning to alert the driver that the oil level is dangerously low. I am also concerned about the recurring catalytic-converter warning, loss of engine power, abnormal engine noise, and the possibility of engine or catalytic-converter failure while the vehicle is being driven. I understand that other Kia vehicles have been subject to recalls and investigations involving engine-related defects. I am asking NHTSA to review complaints involving the 2012 Kia Rio and investigate whether excesRead more
