sign. An approaching vehicle was forced to swerve around us to avoid a collision while I attempted to restart the engine. This incident created an immediate risk of a serious collision and is consistent with the recurring stalling condition I have reported to Prestige Volkswagen of Melbourne for years. The vehicle has approximately 126,000 miles. Despite repeated dealership repairs, the condition continues to recur, and I am concerned that the vehicle may stall again without warning. I am requesting that NHTSA investigate this recurring engine-stalling condition and the repeated failures of the EVAP system components.

I am filing an immediate safety complaint regarding a severe engine defect on my vehicle and the manufacturer's dangerous diagnostic protocol. The vehicle is experiencing active engine failure symptoms, including [insert symptoms here, e.g., severe knocking, sudden hesitation, intermittent stalling, or a flashing check engine light]. I have clear video evidence of the failure, and the dealership's Shop Foreman inspected the vehicle and diagnosed it with an internal engine problem. Despite a formal diagnosis from...

their own Shop Foreman and video proof of the failure, Hyundai Techline is attempting to deflect liability by blaming a previously installed aftermarket oil filter. The dealership has since replaced the aftermarket filter with an OEM filter. However, instead of repairing the diagnosed internal engine defect, they are forcing me to drive this malfunctioning vehicle for an additional 1,000 miles to "duplicate" the issue. Operating a vehicle with a known, documented internal engine failure on public roads poses an immediate and severe safety hazard to myself, my kids, and other drivers. The vehicle is at imminent risk of sudden engine stalling, complete power loss, or catastrophic mechanical seizure at highway speeds, which could cause a serious collision. The manufacturer is actively demanding that I operate a dangerous vehicle as a condition of their warranty process, shifting extreme physical liability onto the consumer.
The chrome trim surrounding the circular cup holders in the center console has begun separating and peeling away from the plastic. It is lifting around most of the circumference, exposing extremely sharp edges. While placing a coffee cup into the holder, the exposed metal-like trim sliced my finger open and caused an actual bleeding injury. I have photographs documenting both the defective trim and my injury. I have also become aware of other owners reporting similar problems with the same component in Jeep...

Grand Cherokees. I consider this a safety hazard because the cup holders are used regularly by both drivers and passengers, and the exposed edges can cause lacerations. I would like to know whether Jeep has received other complaints about this defect, whether there are any technical service bulletins or investigations involving this component, and whether Jeep will cover the repair.
I own a 2025 Dodge Charger Daytona R/T that recently experienced a complete electrical shutdown and no-start condition. The vehicle displayed a Service Electric Vehicle System warning and eventually became completely unresponsive, including its locking functions. It was only restored after an external jump-start using another vehicle's battery.
My vehicle throws itself into park and shuts off at traffic lights and stop signs. This has happened at least 6 times. I bring it in to be looked and nothing is found but this keeps happening. The AB switch light activates when this occurs.
The power brake booster malfunctioned, losing power brakes, greatly increasing stopping distance. Vehicle has 92000 miles on it.

While attempting to execute a left-hand turn across oncoming traffic, the vehicle suffered a severe and sudden throttle hesitation and loss of acceleration power. Despite applying pressure to the gas pedal, the vehicle failed to accelerate quickly enough to safely clear the intersection, creating an immediate, life-threatening safety hazard with oncoming traffic. There was about a 6-second delay and this kept happening. Following the hesitation, the vehicle accelerated painfully slowly. Prior to this incident, a...

heavier rumble or rough idle was noted upon engine startup. There was no Check Engine Light or warning message displayed on the dashboard. Bypassing the issue via Sport Mode was unsuccessful. This is a brand-new vehicle leased only two weeks ago. I am fearful to drive it at this point.
We have cleaned the lenses where they are in new condition. Replace the bulbs with high-quality bulbs and the ability to see at night has not improved, causing a serious safety concern that we have now considered having to sell the car. Acura has issued a recall for the same problem on a different model for the same problem but has extended it to cover the RDX.
When driving around turns where the steering wheels turns more than 50 degrees, the steering struggles to return to straight and is sticky. Along roads with horizontal curves, I must pull back to center when trying to exit a turn as the wheel is sticky (wants to stay at the angle needed to turn)
While driving at highway speeds of approximately 65 mph, the vehicle suddenly suffered a catastrophic loss of propulsion/motive power in active traffic. The engine oil temperature surged, and the vehicle completely lost power, forcing me to navigate across lanes to the shoulder without engine power, creating an immediate, severe safety hazard of a high-speed rear-end collision. The vehicle had to be towed via flatbed. This vehicle previously had an open recall for this exact issue under NHTSA Recall 25V-274. The...

GM dealership closed the recall on September 2025. by applying the authorized remedy: replacing the engine oil with 0W-40 and installing a new oil fill cap. No component replacement was performed because the dealer stated it passed inspection.
At approximately 31,000 miles, the factory hydraulic engine mounts experienced an active fluid leak and mechanical failure during routine operation. This vehicle has been regularly maintained and operated strictly under normal passenger driving conditions. The premature loss of internal hydraulic fluid compromises the structural support and alignment of the engine assembly. In this chassis, collapsed or leaking engine mounts allow excessive engine displacement, rotation, and torsional movement under acceleration...

and braking. This condition creates direct safety hazards: (1) Significant driveline misalignment that increases stress on adjacent critical components, including the exhaust downpipe, turbocharger plumbing, charge-air ducts, and drivetrain couplings. (2) Risk of premature failure or fatigue cracking of the exhaust and intake plumbing, presenting potential exhaust gas intrusion or sudden loss of engine power under load. (3) Excessive powertrain vibration and shifting that impairs vehicle control, throttle response predictability, and transmission engagement during lane changes, merging, or emergency maneuvers. A failure of primary structural engine mounts at 31,000 miles indicates a manufacturing or material defect in the hydraulic bladder and seal design. Because this issue appears widespread across modern BMW 2.0L (B48) platforms, I request that the NHTSA investigate this premature structural failure for potential recall or safety defect determination.
On [redacted], I was driving my 2025 Mazda CX-50 Hybrid in stop-and-go traffic in [[redacted]]. While driving in traffic, the vehicle suddenly accelerated without my intention. I applied the brake pedal in an attempt to slow or stop, but the vehicle did not decelerate as expected. Despite my attempt to brake, the Mazda collided with the vehicle ahead of me, resulting in a multi-vehicle collision. Following the initial impact, my vehicle moved backward and struck another vehicle behind me. I experienced a forceful...

backward movement and felt as though I had been thrown backward. The airbags deployed. Police and emergency medical personnel responded. A child passenger sustained a small cut to her head and was medically evaluated. The police report includes a witness account describing the Mazda's sudden acceleration before the collision. I am concerned about possible unintended acceleration and braking-system performance. The specific mechanical or electronic cause is UNKNOWN. I have not received confirmation that a particular component malfunctioned. The vehicle was declared a total loss by my insurance company. It was expected to be transferred to a Copart facility. I do not know whether the vehicle has undergone a mechanical inspection or whether its electronic diagnostic and event data have been preserved. I am reporting this incident because the unexpected acceleration and inability to slow the vehicle as expected created a serious risk of injury to occupants and other motorists. I request that NHTSA evaluate this incident for a possible vehicle safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Full Self-Driving (Supervised) was engaged, the vehicle began making unexpected and erratic driving movements. During the same drive, I heard an extremely loud noise resembling thunder or heavy metal components grinding against one another. I became concerned that a critical mechanical component could be failing while the vehicle was in motion. I was able to return home safely and have stopped operating the vehicle pending a professional inspection. This incident follows an earlier major malfunction in which the windshield-wiper system failed. Tesla service personnel subsequently informed me that the wiper motor had come apart and that associated damage required brake-system repairs. I believe the combination of unpredictable driving behavior, the severe mechanical noise, and the vehicle's recent repair history warrants investigation for possible safety-related defects. I recorded a short video during the incident and preserved available Dashcam footage. I request that NHTSA review this incident and determine whether further investigation is warranted, including whether similar complaints have been reported involving Cybertruck Full Self-Driving behavior, braking, steering, or drivetrain components. I am willing to provide the recordings, prior repair documentation, and any additional information necessary for an investigation.

My Rivian R1T is experiencing a recurring problem with the 12-volt battery system. Around 2023, while I was traveling in San Francisco, my vehicle displayed a warning stating that the 12V battery needed to be replaced and instructed me to keep the vehicle connected to a charger. I was concerned that the vehicle could become inoperable and leave me stranded away from home. Rivian subsequently replaced the 12V battery. I am now experiencing the same warning again. The vehicle is once again telling me there is a...

problem with the 12V battery and that I need to keep the vehicle connected to a charging port. I depend on this vehicle for transportation to work, and I am concerned that if I disconnect it and drive to work, the 12V system could fail and leave me stranded or unable to operate the vehicle. I am concerned that having the same 12V battery issue occur again only a few years after the previous battery was replaced indicates a recurring durability or design problem with the low-voltage electrical system. A failure of this system can potentially make the vehicle inoperable even when the main high-voltage battery has sufficient charge. I am asking NHTSA to investigate recurring and premature 12V battery failures in Rivian R1T vehicles and determine whether there is a safety-related defect. I am particularly concerned about the possibility of being stranded without adequate warning and having to repeatedly replace a critical component of the vehicle's electrical system.
At approximately 40-45 mph on a local street, the steering wheel physically rotated by itself in my hands. The vehicle crossed the centerline, turned/rotated, and stopped by itself without hard braking, coming to rest facing the opposite direction. The event lasted only a few seconds; I did not have time to notice warning lights. No injuries. Vehicle was police-towed. I suspect a mechanical steering/suspension/brake defect.

A known manufacturing defect is causing my sunroof drain to fail, dumping water into the cabin and flooding the main electrical wiring harnesses under the driver-side floorboard and door pillar. This ongoing water leak has corrupted my vehicle's electrical system, causing multiple erratic sensor codes over the past few weeks. In the past few weeks I have received engine coolant code P0128 and transmission code P0720. Recently, while driving, this short circuit caused my Forward Collision Warning light to come on,...

immediately followed by a sudden loss of vehicle acceleration. My car forced itself into a 3rd-gear 'limp mode.' This unexpected loss of power occurred in active traffic, creating an immediate risk of a rear-end collision.
The vehicle has a "hill- holder" function with manual transmissions that keeps brakes applied for short time after brake pedal is released with clutch pedal depressed. The functional time is excessive and leads to dangerous delays in releasing the hill-holder before clutch engagement can be effected. Often times this led to engine stall while attempting to accelerate from a stop. I had several older VW cars with this feature and none had the excessive delay. I've read of other VW owners who experienced similar...
