2017 Colorado All of a sudden I was just driving down the road going 55mph, and my truck shut off. No warning light just died completely. I almost got rear-ended by the car behind me. I could not start the truck back up at all. If I had been in construction zone someone could have seriously got injured or killed, Huge safety issue. I had the truck towed to the chevy dealer, it took the sever days to find out the issue. The wiring harness behind the motor, was rubbing on the fire wall, causing several wires to become exposed and short out. Dealer even if they put a new wiring harness back in it would have the same problem, based off where it is located. I trying to make sure no one gets killed and recall issued. I contacted chevy customer support they didn't seam interested is fixing a safety issue, no there problem after warranty are over.

Vibration and shimmy of vehicle while driving. The entire truck shakes about every 10-20 seconds. Brought the truck in twice in for the company to fix and they do not understand or recognize the problem. Still not fixed and the North Branch Chevy dealership will not stand behind the warranty or repair.

This is the third time I have had it to the dealership this time. The first time I was told there was nothing wrong with it. The second time, they replaced the torque converter. This time they acknowledged a problem again and and said GM issued a technical service bulletin to address this. I hope this repair works this time. But my concern is, having been repaired before, how long will this repair last, and 2) will it last till the powertrain warranty has expired? having looked through this list since the first problem in 2018, I have some major concerns with the 8 speed transmission in this truck. GM needs to address this by issuing a recall or extending the powertrain warranty on this model. I need this vehicle to last and right now it doesnt look good.

I noticed loud creaking noises on the driver's side of my truck primarily when cornering and going over bumps. I asked ferman Chevrolet (9751 E adamo dr, tampa, fl 33619) to check it out for me. They found that 2 transmission bolts were missing, which they attribute to the noise. I'm not sure if this is something that occurred resulting from poor manufacturing but it seems that this is not something that could/should have occurred through normal use (driving on city roads only about 50 to 100 miles per week) on a 4 year old vehicle with only 30650 miles on it. I looked for recalls for missing transmission bolts for GM products and found that there is one that is possibly a similar issue although only for certain front wheel drive models; N202313440.

My 2017, Colorado 2 wd, 33,000 miles, began to rumble, intermittently at hwy cruising speeds. It feels and sounds as if I'm driving over hwy rumble bars. Rumbling stops as soon as I take my foot of the accelerator. This phenomenon began as an occasional annoyance but has increased significant to a daily event. I've scheduled a transmission fluid change with the dealer in two days.

Torque converter clutch 'shudder' at loaded steady speed and acceleration - vibration felt in entire cabin @ 15,560 miles. Non-existent while coasting/off-throttle. Prevalent when drivetrain is fully warmed up & on highway. Extremely annoying.

- Green Bay, WI, USA

Transmission: My vehicle was making a sound, as if something was rubbing. Called dealer from where I purchased it and they replaced the transmission fluid. I'm not comfortable with just replacing the transmission fluid. Hoping to not have something else going on with transmission. They replaced the transmission fluid with a different type of transmission fluid. I had just entered interstate 81, when the runbbing sound, started to occur. The service advisor told me the transmission fluid that was originally put in when it was manufactured, was the wrong fluid.
