CHEVROLET Complaints

I observed my mother’s 2007 Chevy Cobalt was leaking fuel near the rear tire by the fuel tank. I inspected the tank with engine off and it does not leak. Only with engine running. I lowered the tank and observed a small crack on the plastic return line on the fuel pump module. I started looking online and could not find a replacement part that was plastic. I then conducted more research and found the recall. I asked my mother and she stated she never received a recall. The recall was issued on 09-19-12. NHSTA ID#12v459000

While driving on the freeway with my family in the middle of a snowstorm, my 2025 Silverado 1500 with 8,000 miles on it, suddenly dropped gears down to 1st without warning. The check engine light went on and I later found out it was the valve body that caused it. This could have cause serious harm to my family had I not maintained control of the vehicle. The dealership fixed the problem only for it to happen again a month later. The truck is still in the shop.

Transmission has jerked/bumped in past and now at approx 85K miles, it supposedly needs a new transmission. I've heard it is a pretty big issue and seems llike relatively low mileage for this to be happening to 2023 year model. I certainly don't drive it hard and rarely tow or haul heavy loads.

I purchased a 2026 GM Chevy Silverado. At 500 miles all dash warning lights came on while driving, radio played static. I disconnected battery in order to reset the computer. At 1400 miles in the heat of south Florida the air condition stopped working. after completing my drive 60 miles away with no ac i disconnected the battery to reset the computer. The ac started to work after this reset. I went to the dealer and they wanted me to leave the truck. They could not provide a loaner and the fact that this is my only vehicle I could not leave it. At 2000 miles the computer screen stated that there was an update. The computer would not update when I pressed start update. The screen then said unable to update conditions not met go to the dealer. I went back to the dealer and they said there is no update and they reset the computer. THIS IS GOING TO KILL SOMEONE WHEN THEY PULL OVER ON THE HIGHWAY BECAUSE THE CHRISTMASS TREE ON THE DASH CAUSED THEM TO PULL OFF THE HIGHWAY AND A SEMI IS GOING TO KILL THEIR ENTIRE FAMILY WHEN THEY ARE STOPED ON THE SIDE OF THE HIGHWAY BECAUSE GM CANNOT MAKE A VEHICLE THAT WORKS CORRECTLY. PLEASE GO AFTER GM THE COMPANY THAT STOLE YOUR TAX DOLLARS WHEN THEY WENT BANKRUPT.

Was driving vehicle and it revved very high and then got stuck in a single gear. MPG have also been impacted as of late. GM saying VIN isnt under the valve body recall, but dealer has determined the valve body needs to be replaced.

Safety restraint system is on the screen and the airbag icon is on the dash. All of a sudden No accident occurred

While driving on the freeway at approximately 75 MPH my 2022 Chevrolet Equinox lost power, the engine stalled, and I was forced to pull over into a construction zone. The engine would not restart and the check engine indicator was on. OnStar messaged me via email that a fault P129F was detected. I had the vehicle towed to my home where I performed some additional diagnostics and determined that while similar to Product Safety Recall N222372310 Inadequate Fuel Pump Flow, the issue was not with the fuel pump but with the fuel pump controller module mounted under the vehicle. I replace the module with an official GM replacement module part number 13554821 which resolved the issue with the fuel system in my vehicle. I still have the faulty fuel pump controller module in my possession (see attached picture).

Vehicle: 2019 Chevrolet Traverse Issue: “Shift to Park” warning – vehicle fails to recognize it is in Park I am filing a complaint regarding a persistent &dangerous defect with my 2019 Chevrolet Traverse involving the “Shift to Park” warning system. For the past several years, my vehicle has repeatedly failed to recognize that it is in Park, even when it clearly is. This issue has escalated into a serious safety and reliability concern. Most recently, I was stranded in a store parking lot for over two hours because my vehicle would not properly shut off or restart due to the false “Shift to Park” warning. I had to call someone to disconnect the battery to prevent it from draining completely, which caused additional cost and inconvenience. After reconnecting the battery, the vehicle still would not start for another 2hours. This defect leaves me at risk of being stranded at any time, including in unsafe or isolated. As a single parent of 4 young children, this creates a significant safety concern for my family. This problem has been ongoing since Oct 2023 and has occurred repeatedly since then, and consistently every month since then, often four or more times per month. I have brought this issue to a Chevrolet dealership, Reed-Lallier Chevrolet in Fayetteville, NC, multiple times. Despite being charged diagnostic fees, no permanent fix has been provided. This is a known issue with this vehicle model related to a faulty shifter assembly or park detection system. This defect impacts the vehicle’s ability to shut off, restart, & function reliably, creating a serious safety hazard. I am requesting that this issue be formally investigated & that appropriate action be taken to require a recall or manufacturer-covered repair. This problem is widespread among similar vehicles & should not continue to leave drivers stranded or at risk. Mileage: 44,410 miles Dates of occurrences: Oct 2023-present Dealer contacted: Reed-Lallier Chevrolet on Raeford rd Fayetteville NC

When you put the vehicle in park, it does not register on the dash that the vehicle is in park so therefore you cannot turn the vehicle off. I’ve read this as well known in the 2021 trailblazers

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at 70 MPH, the vehicle hesitated while depressing the accelerator pedal. The vehicle continued to lose power with a huge cloud of white smoke coming from under the hood. There was no warning light illuminated. The contact pulled off to the shoulder of the roadway, and the vehicle shut off unexpectedly. Due to the failure, the vehicle was towed to the dealer and was diagnosed with engine failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 20,000.
