2021 Chevrolet Colorado Electrical System Problems

The engine coolant temperature gauge is stuck at approximately 160•F. Cooling fans are running at high speed constantly. The thermostat is stuck in the open position. The vehicle is less than 100,000 miles. There is a “Special Coverage Bulletin N242484760” that has indicated the issue is occurring regularly with my type of vehicle but my specific VIN is excluded due to misplaced parameters. The part is readily available at the dealership in which we are getting the part fixed because so many vehicles of my make and model are having this issue. The cost of the repair will be $1,200 and will be out of pocket because my VIN is excluded but clearly affected by the same faulty system for the coolant. This is a mistake as my vehicle is have the exact same issue as all of the others “covered” in the special coverage. We are seeking an appeal and want to file a complaint that my vehicle is excluded and will have to pay $1,200 where other customers will not be required to do so.

When truck is put into park the key will not turn to the unlocked position, the key only goes as far as the accessories position. Not sure that the truck actually goes into park since I can not remove the key without playing with the shifter. This is a continuous problem with the truck

Beginning at approximately 80,000 miles I began to notice I could not remove the key from the ignition switch at times. Turning the vehicle on and off, shifting repeatedly into park, turning the steering wheel and pressing the brake had no effect. I now have 90,000 miles and the problem occurs about half of the time when trying to exit the vehicle. It is dangerous to leave the vehicle with the key still in the switch. I called the dealership and they said they were familiar with the problem and if it was like others they had encountered, it would require changing out the shifter mechanism. I took the Colorado to the dealership on 9/10/2025 and the diagnostics showed that it was a switch problem in the shifter. The repair was $720.15 which I had completed. The shop people said it was a fairly frequent issue with that model and some others

The contact owns a 2021 Chevrolet Colorado. The contact stated that while driving 45 MPH, the vehicle lost automotive power. No warning light was illuminated. The contact pulled over to the shoulder and the started and fuel pump fuse were replaced as a temporary repair. The vehicle was towed to a local dealer, where it was diagnosed and determined that the starter and fuel pump fuse needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same local dealer; however, after the second attempt to repair the vehicle, the failure persisted. The vehicle was taken to Stingray Chevrolet (2002 N Frontage Rd, Plant City, FL 33563); where the vehicle was purchased, and the contact requested a second opinion. The contact stated that the vehicle was repaired; however, the failure reoccurred. The manufacturer was made aware of the failure. The failure mileage was approximately 27,000.

My radio volume goes nuts and the controls go unresponsive, The unit brings the volume up to max I can not hear emergency crews if they are using the siren. This also creates a safety issues as now I am taking my eyes off the road to try and stop the problem. The infotainment system is failing yes the truck is available for inspection. I have taken video of the problem and sent it to the dealer. The vehicle has not been inspected by police or insurance rep, as far as manufacturer as this truck has been back to the dealer more then 4 times I fell that would be the manufacture as they are certified by GM. GM knows that there is an issue with the infotainment system, not sure why they have not done a recall on this unit. No warnings are given before this happens. This problem first showed up when the truck had about 3,000 miles on it I bought the truck brand new.

There are crackling sounds coming from the wheel when going over humps. no power while driving or changing lanes it's worst when the ac is on, was burning gas like crazy, and shakes at 65 mph., the gas while escalating makes a clicking noise like 2 iron knocking together, and the dashboard including the radio, and telephone screens goes blank/black. from time to time from day one, the truck drop dead/blank in August 2021, AC comes on while not on time to time. the tire sensors read wrong, the door is making clicking noise, outside air is coming into the cabin, and exhaust fumes. It's very damp by my feet and under the steering under the driver's feet it's rusty, the safety alarms are on from time to time. From time to time the belt will squeeze while driving. Yes, the truck has been at the dealership lots of times, every time they claim they can't find the leaks or the problem! and refuse to set up any warranty repairs.
