CHEVROLET Complaints

I have received a Code 95 error message for my 2018 Chevrolet Spark, which per the GM owner's manual means that there is an air bag problem. But, the alert does not appear consistently when operated. When driving, it does not appear. The problem has not been reproduced or confirmed by a dealer or independent service center. The code only comes on after the car has been idling and not being driven (for example, it takes 2-3 minutes while in park but the engine being on for the code to come up on the screen). If the car is put into drive a minute or less after turning the ignition, the code does NOT appear; it only does when parked and the engine is running after a few minutes. The car is available for inspection upon NHTSA/DOT request. My safety is put at risk if the air bag does not deploy; if the alert code does not consistently appear when the car is in operation, it puts my safety at risk because I would not have any indication that there is a possible problem. The car has not been inspected by the manufacturer (to my knowledge), police, insurance representatives, or others. This has occurred at least three times since the start of 2026, with the most recent occurrence in June 2026.

Acceleration issues. Started once put in drive didnt want to accelerate, acceleration issues now at higher speeds while driving

Rear steering knuckle and control arm knuckle.my car moves side to side. I have replaced everything in the rear end. I just recently bought this car.

My 2018 Chevrolet Colorado diesel has had repeated diesel emissions/DPF-related failures that cause the vehicle to enter reduced-power or limp mode. This is a safety issue because the truck suddenly loses power and cannot accelerate normally. The most serious incident occurred while driving over Santiam Pass in Oregon. The vehicle went into reduced-power/limp mode on a mountain highway, leaving me unable to maintain normal speed or accelerate safely. I lost power needed to pass traffic and had limited ability to respond to road conditions. The problem has happened several times. It has also occurred while I was towing my boat, which left me unable to continue the trip safely and created a hazardous situation because the truck could not maintain normal towing power. The issue appears related to the diesel particulate filter/emissions system and repeated DPF/regen or exhaust aftertreatment problems. I am concerned that a design, calibration, or emissions-system defect is causing sudden power reduction during normal driving and towing. This creates an unreasonable safety risk, especially on mountain passes, two-lane highways, and while towing. I am requesting that NHTSA review this as a potential safety defect involving the 2018 Chevrolet Colorado diesel DPF/emissions system and reduced-engine-power strategy. I am also requesting that this complaint be considered with any similar complaints, recalls, technical service bulletins, or emissions campaigns related to DPF regeneration, particulate matter sensor diagnostics, reduced engine power, or limp mode on the 2.8L Duramax Chevrolet Colorado.

Since buying the vehicle I’ve had issues with the truck going into limp mode with codes p0700 as well as p0747. I have taken it to the dealership twice now, when it has arrived the codes were no longer there. Every time the truck went into limp mode the transmission would get stuck into 5th gear stuck at 45 mph. The problem with the truck started at 48,000 miles, the truck currently has 60,000 miles and the problem has been more active. With the dealership not wanting to resolve the issue the truck was taken to another shop to try to fix the transmission.

The contact owns a 2024 Chevrolet Malibu. The contact stated that the vehicle was parked and turned off in front of the hotel lobby. Moments after entering the hotel, the contact informed that the vehicle had rolled down the hotel driveway and crashed into two parked vehicles located in the hotel parking area. No injuries were reported. A police report was filed at the scene, and the vehicle was driven away. The cause of the failure was not determined. The manufacturer and local dealer were not notified of the incident. The failure mileage was 45,000.

We purchased our 2022 Chevrolet Silverado 1500 ZR2 in XXX, it was discovered in the purchase process that the vehicle had an active recall on the engine which was pending a "fix." This was completely downplayed by the dealership as a minor issue that would be addressed. We waited several weeks for the "fix," which was essentially a change in the oil viscosity. On XXX, our [XXX] son, was out of town, driving the vehicle, which suddenly lost all power on the highway leaving him completely stranded. The vehicle would not turn over at all or even shift into neutral. There were no warning signs, no sensors activated, in fact, the Chevy App showed (and still shows) the vehicle as "everything looks good" "no diagnostic issues!" We had the vehicle towed back to our hometown/dealership (Missoula, Chevrolet in Missoula, MT), where it has now been determined, the engine completely seized up/failed, the original "fix" was not adequate, and we are now waiting for a new engine to be put into the vehicle! After reading about other vehicle owners experiences, I am quite skeptical of the new engine as there have been multiple experiences where the new engines had the same issue. This recall is impacting the safety of drivers, most concerning was our [XXX] left stranded in a rural area with very spotty cell service, and the vehicle would not even shift to neutral to get it to a safer area, this needs to be addresses as soon as possible to prevent others from being put into this situation.

The contact owns a 2022 Chevrolet Equinox. The contact stated that while driving at 30 MPH, the vehicle lost motive power upon depression of the accelerator pedal. The contact coasted the vehicle into a parking lot as the instrument panel displayed the message: "Shift the transmission into Neutral (N), then turn the key or press the engine Start/Stop button to restart the engine." After several unsuccessful attempts to restart the vehicle, the vehicle was towed to a dealer, where it was diagnosed that the fuel pump had failed and needed replacement. The contact researched the failure and discovered NHTSA Campaign Number: 23V013000 (Fuel System, Gasoline); however, the VIN was not included in the recall. The manufacturer was notified of the failure and confirmed the VIN was not included in the recall. The contact was referred to the NHTSA Hotline to file a safety complaint. The vehicle remained unrepaired in the dealer's possession. The failure mileage was approximately 55,000.

While shifting my vehicle from Park, a "Service Transmission" warning message appeared on the dashboard. The warning would illuminate and then disappear, but the vehicle continued to shift into the other gears. At the time the issue occurred, my truck had only 47,000 miles. I brought it to Blasius Chevrolet in [XXX] on XXX, for diagnosis. The dealership determined that the Transmission Control Assembly (Part # XXX) had failed and needed to be replaced. I was informed that this repair was not covered under the powertrain warranty because Chevrolet considers the Transmission Control Assembly to be excluded from powertrain coverage, and my basic warranty had already expired. I was quoted more than $900 for parts and labor. Initially, I was told the replacement part would arrive within a few days. Later, the technician stated that other Chevrolet dealerships had the part in stock. However, after contacting those dealerships, he was told they would not release their inventory. Chevrolet then advised that the part was on national backorder, with the earliest estimated availability of XXX. As a result, I have been without my truck for approximately one month, creating a significant hardship. After researching this issue, I found numerous reports from other Chevrolet owners experiencing the same failure involving the Transmission Control Assembly. The apparent frequency of these failures, combined with the nationwide backorder of the part, suggests this may be a widespread defect rather than normal wear and tear. I believe Chevrolet should either: Cover this repair under the powertrain warranty, as it directly affects the operation of the transmission, or Issue a recall or warranty extension if this is determined to be a common defect affecting vehicle safety and reliability. I am submitting this complaint because I am concerned that a failure of the Transmission Control Assembly could impact the safe operation of the vehicle.

GM installed Advanced Monitoring Software on the car rather than replace the battery. The software detected a battery fault. Under the battery recall if a fault is detected the battery is replaced free of charge. GM is refusing to replace the battery. Now the car will not move.
