Ignition switch fully won't turn to off position. Engine does turn off, but key can't be removed. Happens frequently and so far, starting it, putting it into drive or reverse and move a bit, then back into park will work. At some that might not work and I'd have to leave the key in the ignition and leave the truck unattended. I could still lock it, but if some kids see it or break into it, they could drive it away. Chevy knows about this. There is a service bulletin #pi1429B.
2018 Chevy Colorado ZR2, 21000 miles. Engine shut down while driving in motion on road. Restarted twice and shutdown again twice. Check end engine light came on and traction control said it was disabled. Started third time and put in drive. Wouldn't put power from engine to drive train. 4th start, put in drive and limped back home. Was towed to closest dealer and they cleared error codes with diagnosing. I scanned codes before being towed and error codes were U0700 and U0100. After 3 days of no comms from 1st dealer had 2nd dealer pick up via tow truck. They said 1st dealer cleared codes and could not duplicate. Picked up truck and ran fine for a week, then had same issue on busy road. Had to restart, engine light came on and limped back home. Scanned codes and received same U0700, U0100. Dealer is having tow truck pick up truck to diagnose and repair. This is a serious issue causing truck to shut off while driving and not knowing if it will restart and have power to drivetrain.
When turning the key into the ignition position the vehicle will give a random downshift unless the brake pedal is pressed down. Also experiencing a rough downshift between 2nd and 1st gear when stopping as smoothly as possible. Vehicle as been in and out the dealership with the problem still existing.
About a year ago, I started getting a slight shudder in my transmission so I took it to the dealer for repair. They couldn't get it to shudder. Several times I'll be driving down the road at or around 45mph and the truck will start shuddering so bad I feel like I have to pull off the road. Every time I take it to the dealer for repair I end up losing my truck for a day and they tell me they can find anything wrong even though this is a known issue and there is a tsb out to fix the issue.
While driving on city street and highway, transmission shifting at speeds of 25mph,45mph,55mph start vibrating also coming to a stop feel like a rear end bump.

The truck vibrates, stutters some times when driving. Went to dealer he said it has been happening in trucks. He said thicker trans oil should fix it. Is this just a band aid for a bigger problem. Would like your view. Thanks.
I am writing to inform you of a safety issue with my 2018 Chevrolet Colorado. When putting the vehicle in park the ignition key will not release. Chevrolet doc# 4811390 documents a fleet wide problem with the Colorado. There has been no re-call issued by Chevrolet to correct this safety issue. I got my Colorado repaired at a cost of $642.15. I looked at the shifter that was removed from the truck, and found that the micro switch that activates when the vehicle is placed in park had a broken mounting post causing it to be misaligned. I have included pictures of the switch and mounting post.
My Colorado has completely shut down/powered off when making a right hand turn. Twice now. I'll be coming to a complete stop, accelerating through the turn and then all of the sudden, without warning, the truck loses all power. No flashing dash, nothing. I have to coast to the shoulder of the road, turn on the hazards, put in park, and restart the vehicle. This has happened twice now. From some online forums I've read, the problem only seems to get worse and has happened to others around 30-40 mph. My car is still under manufacturing warranty for another 500 or so miles. I took my truck into a certified Chevy repair shop and after a week of troubleshooting and trying to recreate the problem, they have found "nothing" wrong with the car. If this doesn't get fixed and continues to occur, it's only a matter of time before an accident happens.
My 2018 Chevrolet ZR2 started to hard shift between first and second gear. It also sounds like it is running over rumble strips when driving between 50-75mph. When I researched this issue, I found thousands of issues online that matched this problem 100 percent. It is called the Chevy shake or the GMC shutter. Mind you, the dealership verified that they have been sent kits from GM to correct these issues. It's called the tcc shudder.
The transmission in my truck shakes, shimmies, vibrates, shutters when driving and shakes, shimmies vibrates even at idle. I took the truck to the dealership and they removed all of the transmission fluid and replaced with new fluid as per Chevrolet corporate mandate. The truck remains in shaking, shimmies, shutters and vibrating.
Transmission shuddering. - identified variable speed occurrence could happen at 25 or 65. Unrelated to tires/steering or to shock cavitation or rough roads. Happens on smooth or rough roads. Vehicle has not been off-road. Varied inconsistency. More apparent when engine is cold shifting from 1st to 2nd to 3rd then will dissipate. Shifts hard 1st to 2nd and sometimes 3rd when engine is cold. Once warm shifting is smoother but shuddering still occurs.
Some time it feels as if you are riding on the rumble strips on shoulder of the road and some times it shifts pretty hard the rumble can happen at anytime
