2025 Chevrolet Silverado 1500 Complaints

ELECTRICAL SYSTEM,STRUCTURE — Filed 07/09/2026

On Thursday, July 9, 2026, at approximately 2:30 p.m., I was driving my 2025 Chevrolet Silverado 1500 Duramax on Highway 40 while towing a properly connected trailer. The Multi-Flex tailgate had been fully closed and latched before I began my trip and had not been opened at any point prior to the incident. While traveling on the highway, a California Highway Patrol officer pulled alongside my vehicle and alerted me that my tailgate was down and bouncing on the trailer I was towing. I immediately pulled over to the shoulder and observed that the entire Multi-Flex tailgate had unexpectedly unlatched and was resting on the trailer. I closed and latched the tailgate, which appeared to operate normally, and continued to my destination. At no time before or during the incident did the vehicle display a "Tailgate Open" warning or any other warning message on the instrument cluster. The unexpected opening of the tailgate caused it to strike the trailer, resulting in damage to the Multi-Flex tailgate, the rear bumper, and the trailer. The vehicle has approximately 11,000 miles, was purchased new, and has not been modified. I have opened a case with General Motors, and the vehicle is scheduled to be inspected by an authorized Chevrolet dealership.

POWER TRAIN,ENGINE — Filed 05/29/2026

My truck (2025 Chevy Silverado Trail Boss LZ0 Duramax 3.0l) started to have problems when driving. At a stop light, I started to accelerate at about 2000-3000 RPM. While doing so, there was a loud ticking/grinding noise coming from the transmission/Bell housing area. On June 2nd, I dropped the truck off with the dealership. I didn’t hear back from them until about a month later (July 3rd) and when I did they said the technician confirmed I needed a new ‘axle actuator’. About a week and a half later, they said it did not fix the issue and started to become more of a problem to where they will need an “engine technician” to see if I need a new engine due to the “crank shaft thrust bearing”. The advisor said he will call me on Wednesday, July 15th to update me on what I will need. I requested a Loaner vehicle since I dropped it off and they said no because the dealer does not provide that and would have to get approval from GM to grant me the loaner vehicle bast off the diagnostic.

Leased a 2025 Chevy Silverado in late 2025. On June 13th 2026 driving home my vehicle all of a sudden had very little power, check engine light went on and thankfully I was at my driveway. Pulled into my residence, shut truck off and called the dealer I leased the truck from at 1:00 pm Satuarday, June 13th. They set me up with a loaner vehicle. I called for a tow truck Monday the June 15th and had truck delivered to dealership. Ive been told, they are looking into? Beyond that, nothing more.

UNKNOWN OR OTHER,ENGINE — Filed 05/12/2026

My 2025 Chevy Silverado 1500 6.2L V8 experienced an internal engine failure at approximately 16,500 miles, requiring replacement of the entire long block under the factory powertrain warranty. The authorized Chevrolet dealership diagnosed internal cylinder wall scoring, and the engine could not be repaired. The failed engine should still be available for inspection if requested. About 4,000 miles after my last oil change, while the Oil Life Monitor still showed about 50% remaining, the vehicle repeatedly displayed "Engine Oil Level Low" warnings. I checked the oil level with the engine cold, and the dipstick showed the level was normal, so I believed the problem was a faulty oil level sensor. The next day, the warning changed to "Add Engine Oil," and I immediately took the truck to the dealership. The dealership confirmed the issue was not the sensor but internal engine damage caused by cylinder wall scoring, requiring replacement of the entire long block. Fortunately, the engine did not seize while I was driving, and no crash or injury occurred. However, before the failure was diagnosed, the only warning was repeated oil level messages that did not match the actual oil level. There were no abnormal engine noises, knocking, or noticeable loss of power. A driver could reasonably assume it was only a sensor issue and continue driving without realizing the engine had already suffered severe internal damage. If the engine failed while driving, it could create a serious safety hazard. Although GM replaced the engine under warranty, I remain concerned that a vehicle less than 16 months old with only 16,500 miles experienced such a major engine failure. I am also concerned that similar failures could occur after the factory powertrain warranty expires, leaving owners responsible for repairs that other Silverado owners have reported can cost approximately $13,000. I respectfully request that NHTSA investigate whether similar failures may also affect 2025 6.2L V8 model.

Date: June 22, 2026 Time of Incident: Approximately 11:48 a.m. Vehicle: 2025 Chevrolet Silverado High Country 6.2L V8 Current Mileage: Approximately 29,500 miles I am documenting the events surrounding the unexpected engine failure of my 2025 Chevrolet Silverado High Country. On June 22, 2026, at approximately 11:48 a.m., while driving at highway speed, the vehicle was operating normally with no warning lights, messages, or other indications of a problem. I began hearing a metallic clanking or knocking noise from the engine area. The noise progressively increased in volume and severity over approximately ten minutes as I reduced speed and looked for a safe location to pull over. My intention was to reach the dealership if possible; however, as I slowed to approximately 15 mph to make a turn, the noise stopped abruptly, the engine shut off, and the vehicle displayed a message instructing me to press the Start button again. The vehicle came to a complete stop at approximately 11:58 a.m. I attempted to restart the vehicle once, but it did not restart. No additional restart attempts have been made. There were no warning lights displayed prior to the engine shutting down, and there were no visible fluid leaks underneath the vehicle after it came to a stop. The vehicle received a routine oil change on June 16, 2026, approximately three days before this incident. I have retained the service receipt and all related documentation. The vehicle will be transported by flatbed tow truck to an authorized Chevrolet dealership for diagnosis and repair under warranty. This email is intended to document the incident timeline and details while they are fresh in my memory. I have not heard back from the dealer yet.

1st incident My son was driving the truck when all the emergency lights came on. He pulled over and the engine was on fire. He ran to a strangers house to get buckets of water not safe for my child at all. Come to find out that an engine rod slipped and put three holes through the engine causing oil to spill and a fire unbelievable! Lucky my son wasn’t injured. Chevy blames my son for that! Not acceptable! 2nd incident 1 month later my son calls and tells me when he started the truck it began making noise. He again got stuck with this truck because it lost complete power. Come to find out the transmission went. Chevy blamed my son again! Really come on! We have paid more for this truck than drive it. Now they are taking the warranty away. Please help.
