CHEVROLET Complaints

Component or System Failure The vehicle experienced two major mechanical failures. First, the transmission failed and required full replacement shortly after the expiration of the 60,000-mile powertrain warranty. At the time of this failure, the vehicle had approximately 61,000 miles. Second, at 100,119 miles, the engine suffered a catastrophic failure that required complete engine replacement. Safety Risk The transmission failure impaired normal drivability and created a safety risk due to reduced or unreliable propulsion, which could have resulted in loss of power while driving in traffic. The engine failure rendered the vehicle inoperable and could have posed a serious safety hazard if it had occurred while the vehicle was in motion, including sudden loss of engine power. Problem Confirmation and Inspection Both failures were diagnosed and confirmed by dealership service personnel, who determined that full replacement of the transmission and later the engine was necessary. The issues were identified through inspection and standard diagnostic procedures. Warning Lamps or Symptoms There were no clear, persistent, or meaningful warning lamps, messages, or symptoms that would have reasonably alerted the driver to an impending transmission failure prior to it occurring. Any warning indicators appeared at or immediately before the failure. Similarly, there were no significant warning signs that would have predicted the engine failure prior to the need for complete replacement. Additional Information Both the transmission and engine failed at relatively low mileage for major powertrain components. The transmission failure occurred just beyond the powertrain warranty threshold, and the engine required full replacement at 100,119 miles. . These failures suggest a potential defect or durability concern affecting critical powertrain systems.

This has happened two times. Driving down the road between 35-55mph. "Speed limited drive with care" no CEL. Took to dealer, advised with a CEL or no codes nothing they could do for it. Multiple nights I get home and the fan stays running after engine shutdown. Engine overheat within 10 min of drive time. OIL SMELLS LIKE FUEL. This time engine throttles back and nearly caused accident with not being able to merge.

Vehicle has experienced repeated internal engine failures related to the exhaust valve lash adjusters and valvetrain. The engine developed abnormal valvetrain noise, misfires under load, and loss of power. The check engine light would only flash during hard acceleration or when passing another vehicle (wide-open throttle), then turn off after approximately 10–15 seconds and never remain illuminated. Because the warning light would not stay on, the vehicle continued to be operated without clear indication of an active or worsening engine failure. Dealer inspection confirmed exhaust valve lash adjuster failure, which led to camshaft and valvetrain damage. This failure has occurred more than once, including after prior dealer repairs. This is a serious safety concern because the vehicle was driven at highway speeds and during passing maneuvers while experiencing internal engine damage and misfires, without persistent warning to the driver. Sudden power loss, stalling, or catastrophic engine failure during acceleration or passing presents a risk of crash or injury. This appears to be a systemic engine defect rather than normal wear, as the failure recurred and was not reliably detected by the vehicle’s monitoring system.

7.5 amp to fuel injectors has blown 2 times unknow reason causing loss of power 1st time on country road then 2nd time on a highway it's a common problem from the Chevy Colorado forums regarding the 2.8l lwn engine

I purchased a brand new 2026 Chevrolet Equinox Sport Utility on 8/22/2025. 4 weeks later the front end started leaking oil. It has been back to the dealership 4 times for repairs, including replacing the engine. After all these attempts to fix the oil leak it continues to leak oil and we are waiting for the dealer to pick it up again. We are not sure if it is safe to drive but the dealer says to keep driving it. No warning lamps or system messages were triggered during this entire time.

The issue involves the upper corners of all four door frames on my 2024 Chevrolet Trax, which are extremely sharp. The vehicle is available for inspection upon request. On approximately May 13, 2024, and again on August 16, 2025, my passenger in the front seat was struck in the face by the sharp door frame corner, while exiting the vehicle. In both incidents, the corner cut my passenger's cheek below the eye, resulting in small open wounds, which needed to be cleaned and disinfected. The problem has occurred twice under normal use. I reported the first incident to General Motors (GM) on May 15, 2024, but did not receive a response. On Sept 22, 2025, I reported the second incident that occurred on Sept 2, 2025, to GM, at which time they asked several questions and requested photos of my vehicle, which I provided. On Sept 22, 2025, GM requested I take my vehicle to my dealership, J.B.A. Chevrolet, for inspection. I took my vehicle to JBA on Sept 29, 2025, and was told that GM wanted photos of my vehicle, as well as photos of another 2024 Trax on the Lot for comparison. At that time, JBA had to wait for another vehicle to come in. Unknown if JBA or GM attempted to reproduce the issue during an inspection. On Oct 24, 2025, GM telephoned and issued a final determination, which I requested in writing and received on Nov 11, 2025. GM stated that because the design was consistent across Trax vehicles, and based on the facts provided, they were unable to assume responsibility for damages and suggested I resolve the issue with my insurance company. I did not ask for damages, I asked for corrective measures to avoid future injuries. I submitted a request for reconsideration on Dec 2, 2025. On Dec 16, 2025, a totally different GM office contacted me, which did not yield any results. Although the injuries were minor, the repeated nature of the harm indicates a foreseeable risk to future passengers and to other Trax owners. Uploading 10 pages in PDF format

The back sliding window on the drivers side exploded, sounded like a shot gun going off , I had started my truck with the key grabbed some thing to take with me pulled out of my driveway and it exploded , call The manufacturer went through a number of calls. They had a dealership do an inspection and Gm said not there issue , just had it replaced and it is immediately showed signs of overheating with discoloration and defroster lines breaking in the glass immediately after the vehicle got repaired. Certainly there is an issue that needed correction but can’t get the correct help.

On 4/19/24 I was driving at highway speed. The engine started to knock and the check engine light came on. I was fortunate enough to be extremely close to my local Chevrolet dealership and made it there before the engine failed. The truck had 38633 miles on it. They found damaged engine components and repaired only the broken parts. Was under warranty. Truck is still ticking to this day. Took it in for this noise and they said nothing was wrong.

While driving at highway speeds my vehicle lost steering the radio and the hvac turned off. I had abs and brake lights on the dash as well as a service stabilitrac message. The vehicle completely shutoff and I almost had an auto accident. I have not taken it anywhere as I’m to afraid to drive it for fear of having an accident.

My Tahoe 2021 RST has been leaking what smells like diesel. This goes all the way back only months after I bought it new. This came and went sometimes once a week sometimes once a month. And for the next few years many months I could smell it but no leaks but in the last 10 days the diesel leak has been massive. It leaks from under the engine and if the hood is opened the diesel leak is all over the engine. The smell has been noxious sunce the beginning. Over the years the smell was there off and on. Comes and goes. But the last few months it has been everyday. Apparently the shop had fixed and replaced some parts several weeks ago but the smell of diesel never went away. Now it is in the dealer shop again. Because the fuel leak is too massive and the smell is ever worst.
