a/c control knocks out tempter senor and gauge goes to zero and check engine light comes on, gas mileage goings to hell, turn off engine clutch fan runs for several minutes, can still touch water hoses by hand and not even hot.

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 the federal safety agency investigate this issue for a potential safety-related defect and determine whether a recall or manufacturer action is necessary.

I purchased this Chevrolet Colorado knowing there was a potential problem in which the vehicle's battery is drained overnight during an over the air update; I had hoped GM would have a fix by now (but it does not seem they do). From what I've read, along with my own experience, the vehicle is prompted to update software, but in the process of updating, the "computer" system freezes, though the software continues to try and update, thus draining the battery dead. When this happened to me I measured the battery voltage at 4.4 volts...which in many cases can be lethal to a 12-volt battery. Fortunately I was able to get a boost from a tow truck driver, who then drove my vehicle onto his truck. The dangerous part of this problem is timing. I camp and overland in remote areas. Should this happen when I am miles from service or outside of cell range, I could be vulnerable to all sorts of negative forces. Fortunately, the vehicle was seen at a local dealership, but aside from fixing an unrelated recall and updating the stereo, best I understood I am still vulnerable to this problem occurring again.

Battery keeps draining and leaves you stranded at home or at a parking garage. GM knows that over 250,000 vehicles are affected in the Chevy, GMC line and apparently has spread to Cadillac. The problem is that when GM does over the air updates to the vehicles, the computer software will not disconnect and drains the batteries.

3 different issues 1. Automatic emergency braking: Was driving and truck slammed brakes twice at 55 mph to 15mph There was no cars or people anywhere around truck when it happened. The jolt was so bad my neck and my wrist hurt for 3 to 4 days, If there was it would have caused an accident. Took truck in twice once to for recall and 2nd for the brakes slamming. Chevy said they couldnt make it happen again so they cant fix it. I explained it didnt happen for over 11,000 miles so how I just have to wait until it happens again. The light and sound still goes off randomly but brakes haven't slammed yet. Very dangerous this really puts mine and others at risk. 2. Windows don't always go down Part has been on order may still waiting Aug 11, 2024 3. Recently truck won't start battery dead. Going to take in tomorrow. I reached out to gm due to chevy dealer said they are the only ones that can fix issue. That didn't work either. I still have a brand new deg Effective truck. Don't know what else to do. Lawyer says to take it in 2 more times then they can start a case. All I want is it fixed specially when I bought it new.

2 incidents. 1. The blind spot indication (driver side) gives false readings sometimes. Will light up at various times in clear weather with no vehicle next to me. Sensors checked and were clean. 2. The vehicle had a dead battery. It was jumped by roadside assistance. When started, the vehicle had a check engine light. I called Onstar (hands free function built in) to diagnose the problem while driving to charge the battery. Onstar told me what it said and indicated I should take it to the dealer. When I attempted to merge onto OK-51 the vehicle suddenly stopped accelerating without warning causing me to nearly miss another vehicle while merging. When I looked down at the IP, a message came up saying vehicle limited to 62 mph. I wasn’t previously warned or told by Onstar that this would happen (I was still talking to Onstar when it happened and the customer service representative sounded surprised). I did not collide with the vehicle but the other vehicle had to take evasive maneuvers to avoid my unintentional slow merge.

The key repeatedly will not turn to off position and cannot be removed from ignition. This results in my having to leave the key in the ignition. IE: at the grocery store, at the post office, at the drug store etc. I have taken to dealership. The first time for 2 days and they said they could not duplicate the problem. The 2nd time it happened in the service drive. The service advisor saw it but the technician said could not duplicate. This could result in stolen vehicle or dead battery depending how long I have to leave in the on position. The TSB on this says replace shifter control assembly.

Key cannot be removed from ignition. I bought my truck 6 months ago and it’s been in the shop 3 times bc I can’t remove my key. Last time it left me stranded at my veterinary clinic at 1 AM after dealing with an emergency because the battery died. It appears as though I am not the only one having this issue

The key will not come out the iginiton. It takes several minutes to hours turning it back and forth to get it to finally come out. This is a true issue because it drains the battery overnight when you can not turn the key off.
