CHEVROLET Complaints

2025 Chevrolet 1500 Silverado High Country 6.2 L motor with 5624 miles blown motor. When I tried to start it, the motor made a noise like someone tossed a handful of spoons in a blender and turned it on. Motor shut off on its own. This was on Sunday December 21st of 2025. 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)

I am submitting this complaint due to a serious mechanical failure involving the vehicle’s transmission system. The transmission developed a fluid leak that resulted in a sudden loss of proper hydraulic pressure, causing abrupt and unintended vehicle movement while driving. This malfunction created a hazardous driving condition and nearly caused an accident. Given that the vehicle has approximately 77,000 miles, this type of transmission failure is premature and raises concerns regarding a potential manufacturing or component defect. Immediate review and corrective action are requested due to the safety implications of this issue.

Car went to limp mode, hard shifting very suddenly. Transmission system failed. No reverse. Computer codes p0700 p0777 p18A1 inspected at Chevy service center and needs valve body replacement. No warnings, lights, alerts, hard shifts previously.

While driving the vehicle the tailgate came open by itself. I had left my house and when I arrived at my friend’s house to pick him up the tailgate was down. I closed the tailgate and while driving a driver honked their horn to alert me that something was wrong. When I pulled off the road the tailgate had come open for a second time.

Bad shuttering, slow acceleration, clunking noise, check engine light flashing all started while driving home. Took it to a transmission shop and they said it was the TC and transmission. I then called the dealership to see if there was a recall, and looked up any recalls. Since I have had fluid flushed and changed, and still have the problems. This has been an on going problem for a couple of years now. It was just out of warranty for dealership to fix. It started while I was on a highway and had very poor acceleration control.

Repaired a friend's vehicle that had a total brake failure. Vehicle only has 50k miles and no brake repair history. Blew all of the brake fluid out of the stainless braided line coming from master cylinder rear brake channel to abs module. Found the line coming from the front channel to master cylinder also starting to fray and come apart as well. Did not blow out yet. No evidence of brake lines rubbing on any components or that anything has been apart or touched before. Line looks to have failed from the inside out.

The vehicle 'turned off' while in motion at around 35-40 mph on a busy 5-lane major arterial road in the city on 12/21/2025 at around 0630-0700 hours. Driver (author of this report) was able to turn into a side road and stop. Message "Press start button" displayed on dash panel. Complying with this action led to a coughing start but vehicle could not be put into drive mode because a second message appeared saying "Conditions not safe for transfer". Eventually over next minute or two vehicle coughed up to a start again and was able to put into drive mode and drive to parking garage to safety. Driver was able to drive back about 3 hours later with no recurrence or new malfunction. No warning lights throughout the episode. My Chevrolet mobile app also did not display error messages. Vehicle was driven (without incident) and delivered to a Chevrolet dealer on 12/24/2025 for diagnostics and workup and is currently situated there.

The car was driving at 60 MPH on a regular commute to work and the car was stalling and shaking and soon after the check engine light came on with multiple issues.

I've owned the 2022 Silverado High Country with 6.2L engine. Over the past 3.5 years, the engine has had oil consumption issues where I was required to take the vehicle to Chevrolet dealership every 500 miles in Hampton, VA to have the oil level checked. I kept getting the message "low Oil Level" on the information center. I also kept hearing loud ticking noise coming from the engine. Chevy service would top off the oil level (sometimes 1/2 or 1+ quart low), and send me on my way. After oil consumption and ticking noise continued, I was notified by Dealer that a Safety Recall April 2025 was issued by GM. I met with GM Representative and Chevy Service Manager April 2025, and based on my truck history with oil consumption and lifter noise, decision was made to replace engine. New Engine was installed May 2025 and all appeared to be good to go. However, in November 2025 I heard the loud clicking noise in the new engine. Hampton, VA Chevy service conducted an inspection and found a bent push rod in new engine. Service replaced the push rod and all lifters based on history of lifter issues.

Transmission shifts to a low gear and will not upshift causing the vehicle to only go about 10 mph @4,ooo rpm. Dealer says it is a solenoid in the transmission that has failed. Part is on limited distribution because of significant instances of this occurance. This is a dangeruos situation that could cause great peril. My vehicle has only 22,000 miles. This is very premature for this new of a vehicle.
