2021 Chevrolet Colorado

I am reporting a serious safety defect involving my 2021 Chevrolet vehicle. While driving, multiple warnings appeared including “Service Power Steering,” “Steering Assist is Reduced,” “Service ESC,” and “Service Battery Charging System.” The vehicle then lost steering assist, braking performance became unreliable, and it created a serious risk of crash. The vehicle later shut down completely and has remained inoperable. The failure appears electrical and affected multiple critical systems at once, suggesting a cascading system malfunction. Since the incident, the vehicle has not restarted or operated normally. I have replaced the battery, alternator, starter, ignition switch, brake vacuum pump, ECM, spark plugs, fuses, and relays, but the issue persists. The vehicle still shows charging system faults and severe battery drain, indicating an unresolved underlying electrical defect. I have found numerous reports from other 2021 Chevrolet owners describing nearly identical failures, including sudden loss of power steering assist, ESC warnings, charging system failures, battery drain, and complete vehicle shutdowns. This suggests a possible widespread defect affecting this model year. Given the loss of steering assist, braking irregularities, and full vehicle shutdown while driving, I request NHTSA investigate this issue for a potential safety-related defect and determine whether a recall or manufacturer action is necessary.

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.

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

Complete engine failure due to defective crankshaft malfunction, truck taken to certified repair shop and then dealer, deal not responding for 24 days. Engine failed traveling on the highway was fortunately able to pull over, stranded. Engine light came on and the engine failed completely 5-10 min after on a 2 hour return trip home. Certified repair shop informed me this is the exact same reason of the recall just that my vehicle wasn’t currently under the recall. Vehicle component has been recalled on other Chevrolet vehicles manufactured during the same time just not this one yet.

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.

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.

When I stop and try to turn key off it does not turn to off. Have to turn back on and try shifting neutral and back to park. Then try straightened wheel and eventually key will go to off position and take out key. Started few days ago intermittently and now more often. Mileage is 36317 so warranty if expired. I will not pay dealer for analysis since it should be covered under engine. Also have seen 100s of complaints with this online for 2016 thru 2019.
