CHEVROLET Complaints

The component is the Evaporative Emission Control System (EVAP) Vapor Canister Purge Valve.The internal diaphragm or solenoid of the factory-installed purge valve has worn out prematurely or became contaminated, locking it permanently into a stuck-open position.The Manifestation or (Symptoms): The stuck-open valve continuously drafts raw fuel vapor and unmetered air into the engine intake manifold. This causes an improper air-fuel mixture, resulting in:Stumbling / Failure to Start Immediately After Refueling (the engine is flooded by gas tank vapors forced in during fill-up).Rough Idling (due to a continuous vacuum leak).Illuminated Check Engine Light tracking Diagnostic Trouble Codes (DTCs) P0496 (High Purge Flow) or P0442.

The check engine light came on as I cranked the vehicle up and it started idling. No known symptoms until check engine came on prior to failing.

When on the highway and attempted to accelerate to pass in the passing lane, there was a loud pop, the truck rapid decelerated and my son was forced to drive off the burm to avoid being hit by a semi truck. It’s been determined that it was caused by a lifter failure due to the AFM system

Was driving and my car literally wouldn't go forward. Prior to I had an oil change and I would smell burning oil

To make a very long story short, I was having major software issues with my vehicle. I had the car "blackout" lights screens and everything turn off then when it powered on i would have service lights on for my brakes. I also had my reverse camera go out a few times and my lane assistant light on dash say its not working. All to find out i had a faulty rear control module. Upon replacement i learned this EXACT rear control module is the same one used in other GM vehicles noted in several recalls but the part itself has never been directly recalled. So now I have the same exact part in my vehicle again which is bound to fail again at some point. My vehicle is only 3 years old and has done this with children in the car. I let GM know numerous times and they said since the part is replaced its fine. But I know this exact part is not safe. If you look up the model number on the rear control module you will see how many times it is noted in service bulletins and is main contributor to these issues. Please recall the 2023 chevy traverse. I dont want this part just "updated" it needs redesigned.

Lights on the panel reads service parking break, engine, transmission, abs, traffic control and esc service. All these lights are on. Idling rough, white smoke with rich smell. Had a diagnostic read cam/crank and lifters bad… estimated cost 15,000. Total new engine install.

Back up camera stopped working, there is a recall that was not completed before buying the car

The contact owns a 2022 Chevrolet Silverado 1500. The contact stated that while driving 10 MPH, the vehicle hesitated and lurched forward while depressing the accelerator pedal. The contact stated that the failure reoccurred while driving from a complete stop. The vehicle was taken to the dealer, where it was diagnosed with transmission valve failure. The vehicle was being repaired. The contact related the failure to NHTSA Campaign Number: 26V083000 (POWER TRAIN); however, the VIN was not included. The manufacturer was not contacted. The failure mileage was approximately 70,000.

When putting the vehicle in park and turning off, a warning message will appear that states "Shift to Park" and initially a nudge of the gear shift would clear the message, after one week, a simple nudge does not clear the message. The vehicle will not turn off and continues to beep, you have to put vehicle in gear (D or R) move a few feet, return to P, press very firmly on the brake and press the ignition button, this may or may not clear the message and it could take a few attempts of these steps to clear.

The contact owns a 2015 Chevrolet Malibu. The contact stated that while driving on several occasions at various speeds, the vehicle inadvertently shifted between park(P), drive(D), and neutral(N), and the selected gear was not visible or illuminated on the instrument cluster or the gear shifter panel. The doors locked and unlocked, and the engine started shaking abnormally. The contact stated that the message "Service Power Steering - Drive with Care" was displayed during the failure. The vehicle was pulled over to the side of the road after each failure and the gear shifter was slowly shifted between gears until the desired gear was selected. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

I was driving down the XXX Expressway Sunday, XXX, with my children in my vehicle. This is a very heavily traveled highway in [XXX] with heavy traffic. My 2024 Chevy Silverado 3500 Diesel HD Truck with 25,500 miles suddenly started throwing multiple codes, lost power, and steering. Fortunately I was able to "roll into" the emergency lane while muscling the steering in that direction and engaged the emergency brake. My other son was following shortly behind me in his vehicle and pulled over to assist us about 30 mins after my truck was sitting stalled in the HWY. He parked his truck behind mine, put on his hazards, and we were transferring gear from my truck to his truck. At this point my 2024 Chevy HD Silverado Diesel started rolling back on it's own and nearly crushed my son's friend. The parking break was on and it suddenly released on it's own. It took 3 grown men to stop it from crushing my son's friend. The force was so strong that when he lifted his hand to try to stop the truck from rolling, it broke the right rear tail light. He could have been crushed between our two trucks from this situation. I have never been notified by GM of any recalls, however, the truck had to be towed to Ferman Cheverlotte service on Adamo Dr, Tampa Fl and is currently sitting on their lot. I was told by the service tech Michael Stevens that the vehicle had several open recalls that they would address but did not offer any information about what could be wrong. After searching online, I found that GM IS aware of this issue and sent several service bulletins about this exact problem. I had contacted the Ferman service center the week before to bring the truck in because the AC was out and made an appointment for service on Tuesday. The day after I made the appointment my batteries died and had to be replaced by AAA.It is disturbing to know GM and FERMAN Service centers are aware of this safety issue on these HD trucks and never informed me, the consumer.
