CHEVROLET Complaints

Engine oil cooler line leaks and crimping does not hold hose tight enough and slipped off crimp fitting. line came completely off of crimp fitting and leaked all engine oil. Forced engine to be turned off and low engine oil marked on dash.

The tailgate will go up and down when the vehicle is turned off and in park. It will also do this while driving the vehicle. * I notice there has already been a recall for this issue, but my VIN shows NO RECALLS

Transmission issue -while driving 55 mph the RPM’s revved up and the vehicle felt as it it was in 2nd or 3rd gear. Warning lights came on stating “rapid deceleration use caution” and the engine light came on. The vehicle was able to go into park but upon shifting back into drive, it did not change gears. Sounds as if it is being driven in 2nd or 3rd gear with RPM’s elevated.

Vehicle overheated while driving on interstate in 32F weather. No warnings lights warning of low coolant - only noticed climbing temperature gauge and cooling fans running at full speed. Pulled over and drove slowly to nearest exit with service station. Found coolant reservoir completely empty but with no obvious leaks. Chevrolet dealer diagnosed leaking radiator hose - typical with numerous social media report of similar issue with the 2024 model year Chev Traverse Generation 3.

I have read several things about EBCM and the control power circuit being above threshold and wondering if this is a recall for this model? I am getting 3 error codes C0800, B1325, & U0151 for this vehicle. (General Motors is recalling over 449,000 SUVs and pickups (2023–2024 Cadillac Escalade, Chevy Suburban/Tahoe, GMC Yukon, and select Silverado/Sierra 1500) due to a software fault in the Electronic Brake Control Module (EBCM) . This issue prevents the brake warning light from illuminating if brake fluid drops, increasing crash risk.) It's showing the same issues as above.

My 2021 Chevy Bolt keeps showing a battery or power-Propulsion warning light related to the high-voltage system. The warning keeps coming back even after multiple repairs. The first repair was on April 28, 2025, the second was on December 17, 2025, and it is scheduled again for another repair on March 3, 2026. The light is the same every time and affects the car’s performance and reliability. I’m concerned this could be a safety issue involving the battery or propulsion system. The dealer repairs it temporarily, but the warning keeps returning, and the problem has never been fully resolved.

The contact owns a 2022 Chevrolet Tahoe. The contact stated that while driving at various speeds, the contact became aware that the driver's side rearview mirror was pointing upwards or downwards, reducing the driver's ability to see the roadway. The driver's side rearview mirror had been making unintended movements while starting the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 33,000.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the tailgate lowered unexpectedly while driving at various speeds, and occasionally closed unintendedly. The failure also occurred while the vehicle was parked and turned off. The vehicle was taken to the dealer, and the failure was demonstrated. The tailgate switch was replaced. The contact became aware of a Canadian Recall, ID Number: N232426400, for the tailgate failure. The manufacturer was made aware of the failure; however, no repair was performed. The failure mileage was approximately 60,000.

I am reporting a manufacturing defect involving General Motors’ Active Fuel Management (AFM) system. In October 2024, my 2016 Chevrolet Silverado 1500 LT, at 96,000 miles, experienced a lifter collapse which caused sufficient wear to the camshaft that the engine needed to be replaced, which was performed. The malfunction indicator lamp turned on and the truck was driven an additional 2 miles to a safe location and subsequently towed to the repair shop. Before then, there had been no indication that a lifter had collapsed or that there was damage to the engine sufficient to warrant a replacement. In November 2025, I experienced another lifter collapse (on the replaced engine). While the mechanic recommended an engine replacement, the warranty company only authorized a replacement of the affected side cylinder head and lifter, which was performed. In February 2026, I experienced another lifter collapse, and the truck is currently being evaluated by a repair shop. These failures have occurred without warning and aligns with thousands of consumer complaints regarding AFM-related oil consumption, lifter collapse, and engine damage in GM vehicles. This is a known design defect that GM has tried to address through Technical Service Bulletins and engine redesigns, yet many consumers continue to experience premature failures at low mileage. This defect presents a safety and reliability concern, including loss of power while driving and significant financial burden to vehicle owners. I respectfully request that NHTSA investigate this ongoing defect.
