ENGINE
On 11-20-25 while driving vehicle home a loud noise was heard coming from rear of engine. After review and consultation with automative technician it was thought best to park truck in safe location at house and have towed to dealership as engine noise identified aligned with other reports of thrust bearing failures associated with this engine. Driving engine further was considered unsafe if further damage occurred the engine could seize up while on highway. The Dealership tested engine on 11-21-25 in accordance with GM technical service bulletin and confirmed a thrust bearing failure had occurred. A replacement engine and turbo were submitted for order, but not available to due to back order of these parts due to large number of failures of same engine this year. Only the GM dealership that I purchased car from has inspected vehicle at this time and there were no check engine lights in vehicle when failure occurred. I have since identified the GM technical service bulletin was published in September of 2025 and the Duramax 3.0 has had numerous failures throughout 2025, prior to my purchasing vehicle at end of October. GM manufacturing misrepresented the quality of vehicle during the new vehicle purchase and did not disclose the significant number of engine failures that have occurred this year that could have left me and my family in an extremely unsafe situation. Additionally there has been no communication on how the replacement engine equipment manufacturing has resolved the issue that created the initial failure and I am concerned of driving vehicle in future as the engine failure may occur again. NHTSA needs to record this incident and request to GM failure rate data this year and investigate GM for selling vehicles with known manufacturing issues that place driver/passengers in an unsafe condition when vehicle looses power while driving.

Truck as towed to Westly Chapel Chevrolet in Westly Chapel Florida on Monday December 22nd of 2025. Chevrolet Customer Service was called on Monday December 22nd of 2025. The Case # XXX. I spoke to 7 different people before a manager called me later that evening and said my case manager will be Tyisha. The manager stated she was Tyisha's direct manager and that Tyisha would reach out to me within 2-3 days. The manager also stated that she was unaware of the 2021-2024 issues with the 6.2 L motor. I informed Customer Service I wanted a buy back and that 7 Service Departments told me that motor replacements are taking 3-6 + months. Ive been told the repair for the 6.2 L has not been properly addressed and the new motors are still have catastrophic failures. I spoke to 7 local Chevrolet Service departments. Each one said they had several of the 6.2 L motors in with major failures. Some brand new 2025. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
Took 2025 Silverado with a 6.2L engine to get oil changed and tire rotation done. Upon completion drove out of dealership and notice a weird noise coming from engine, then kind of disappeared. Drove home. Wife took car for gym then suppose to go to work. She called stating engine sounded really bad, like a lot of metal and metal screeching. Went to dealership, explained and they towed truck to service department to be looked at on 12/22/2025. Safety to others would have been detrimental if the vehicle had seized on the highway. The dealer person who sent for the tow was not the service manager but when we arrived he heard what the vehicle sounded like. No check engine lights or any warnings on. Hope to have results on Monday.

ELECTRICAL SYSTEM
At random times when you start the vehicle there is no sound. No sound from the turn signals, radio, emergency flashers. Apple Car Play. You have to restart the vehicle to have it reset. You always do not know there is no sound until you have started to drive and go to use the radio of notice that the turn signal is not working. I did not realize that my left hand turn signal did not turn off and at a traffic light I was going straight and a car turn in front of me because they assumed I was making a left hand turn. There was not an accident because they were able to stop. I have had it back to the dealership a number of times. They reset the system. Said it needed a global reset. Even after the reset it still is doing this. Happens more in cold weather. I have recording that are date showing no sound. I have multiple videos but I am unable to upload due to size. I was able to share them with the service technician at Gentilini Cherolet. 500 John S. Penn Blvd. Woodbine, NJ 08270. Phone Number 609-459-0014.

I was driving down the highway with my children to see a movie when my trucks check engine light came on and started surging and losing power we were struggling to drive 5 mph on the shoulder of the road to make it to the closest exit ramp for a safe place to stop. We were able to make it to the ramp but couldn't exit completely because it was an up hill grade. The vehicle was towed to the dealer for a complete engine replacement. The vehicle suffered from a thrust bearing failure.

POWER TRAIN, UNKNOWN OR OTHER
I purchased my 2025 Chevrolet Silverado 2500HD new from Wilsonville Chevrolet in Oregon. Since owning the vehicle, I have experienced a noticeable shutter/vibration at highway speeds, consistently between 70–75 mph, whether towing or not. The shutter feels like it is coming from the transmission or driveline, and it occurs on multiple road types and conditions. I reported this issue to Wilsonville Chevrolet, but they told me they “could not duplicate” the problem and offered no repair. I then took the truck to Power Chevrolet in Corvallis, who stated the tires were out of balance and replaced them. This did not resolve the issue, and the shutter at highway speed remains exactly the same. I also contacted GM directly, but was redirected back to the dealership, resulting in no progress. At this point the issue has been reported multiple times, yet no root cause or repair has been provided. I am essentially being sent in circles without a solution. There appears to be a growing history of transmission-related issues with newer Chevrolet HD trucks equipped with the Allison 10-speed transmission, and this symptom seems consistent with those reports. A shutter at sustained highway speeds raises a significant safety concern, as a transmission failure at 70+ mph could lead to loss of control or power. In addition to the shutter, I have repeatedly noticed a strong “burning brake pad” smell coming from the rear of the truck. This happens randomly and has also been reported to the dealership, but no cause has been identified. I am unsure whether this is related to the transmission issue, but combined, these symptoms suggest a potential mechanical defect. Given the safety implications and the lack of resolution from authorized dealerships, I am requesting NHTSA’s assistance in investigating this issue.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
Purchased new and after 3 weeks (about 600 miles) I was on highway between 60-70 MPH truck started to shutter like it was losing power and would not accelerate. I complained to the sales person and he stated it ran a little rough when purchased first day - I was told it just needs to warm up. Took truck to dealer and they determined at this time it was a misfire and lifter bank issue. There seems to be an issue widespread - I am not comfortable with car and if on the highway i am not able to accelerate properly or becomes unreliable at the time to accelerate I am worried about safety.

ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION, BACK OVER PREVENTION: WARNINGS
Following vehicle startup, the entire audio system defaults to a muted state, affecting all sound output channels. This includes, but is not limited to: Critical Safety Alerts: Seat belt warnings, system malfunction indicators, and door ajar chimes. Proximity and Collision Warnings: Parking assist chimes, Rear Cross-Traffic Alert (RCTA) warnings, and Backup Collision Intervention (BCI) alerts. Communication Systems: Navigation prompts and hands-free/Bluetooth call audio. The audio failure persists until manual user intervention or the next vehicle cycle, disabling critical warning redundancy. Safety Implications The system-wide audio failure directly compromises the safety of vehicle occupants and surrounding pedestrians in two primary ways: Risk to Pedestrians: The silencing of proximity and backup collision warnings (RCTA, BCI) removes a vital layer of redundancy, significantly increasing the risk of striking vulnerable road users, such as children, while maneuvering in reverse. Impaired Driver Safety & Compliance: The defect also removes essential alerts like seat belt warnings and renders the mandated hands-free communication system inoperable, forcing potential driver distraction or non-compliance with driving regulations. Conclusion This audio muting defect is a critical safety failure that disables mandated auditory warning systems, severely limiting the driver's ability to operate the vehicle safely and respond to immediate, unseen hazards. Immediate investigation and resolution are necessary.

traveling at 75 MPH on highway truck went into reduced acceleration mode putting my wife and I in danger. There were many simi trucks having to swerve as my vehicle reduced speed at a high rate and was unable to safetly come to a stop. there was a bulletin released prior to my purchase that was not disclosed that could have warned of potential danger of complete engine loss. was told by dealership engine grenaded dealership confirmed needed new engine and turbo and they are on back order which leads me to believe that I am not the only one this has happened to.
