2018 CHEVROLET COLORADO Complaints

What component or system failed or malfunctioned, and is it available for inspection upon request? It appears to be a piston failure, as there is compression and diesel in the crankcase. Engine is still in the vehicle but once removed it will be available for inspection if needed. How was your safety or the safety of others put at risk? Power loss on a busy highway requiring lane changes without available engine power is dangerous. Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? P0266 code and engine light set immediately after the failure. But there were no warnings prior

We have been complaining to the dealerships (2) since 2021 about a spontaneous outage of the Infotainment system. Each time we were told there was no problem. They claimed to have contacted GM, who said 'no problem' or so we were told. The 'problem' has become a serious safety issue for myself. It starts with a loud constant ‘ticking’ sound that begins after getting seated, even before the key is placed in the ignition and does not stop. The radio rolls a list of station numbers even when nothing is on making it very distracting. Listening to the radio has become impossible. This system malfunction has created a more serious problem for me. At my height, the view of the speedometer reading on the dashboard is blocked by the steering wheel making me dependent on the mph display directly in front of the steering wheel, and is part of the Infotainment system, which keeps going off and I have no way to watch or judge my speed safely. It also interferes when using gps and causes a loss of direction. This is just downright dangerous. As obvious as the problem is, the current dealership requires a $190 diagnostic fee with repair costs to follow. This system was not an option or add-on. We could not break it or wear it out. Now out of warranty GM refuses any responsibility. Why no recall? Many complaints stated on social media.

“Service trailer brake system” won’t turn over but will crank Transmission shifting very hard around 3rd and 4th gear

Master Cylinder leaked into booster an brake fluid got into vac pump. Broke the pump an damaged the end of the cam. Was told metal pieces of cam that broke off where in motor. Had to take a 3600 dollar loss for selling less than what was owed. Car vibration on bad cam. But brakes were repaired with a new pump.

At the beginning of November I was out shopping, when I returned to my vehicle, the driver side door would not open. Luckily I was fit enough to crawl through from the passenger side. I promptly called the Chevy dealership for an inspection/ repair. I feel this was an emergency situation. I didn’t even want to think about what would happen if I were in a vehicle accident, and couldn’t get out, or, no one could get in. I was able to get an appointment at the dealership for November 16, 2023. My Chevy is always parked in covered garage, there was no warning sign of anything going wrong. They checked it at my appointment, but because they couldn’t open it, they decided to order all the assembly parts, which I had to pay for ahead of time. My next appointment for the repair wasn’t set till January 31, 2024. I never knew how important a functional door would be. Very inconvenient, and dangerous.

The check engine light came on because the coolant fan runs for a while after vehicle is shut off. This ended up being due to a thermostat failure. I did have this repaired in Novemver 2023 but what is interesting is that one of my sisters, who also owns a Chevy Captiva had this same thing repaired earlier in 2023 and now my other sister who owns a Chevy Equinox has this same issue now, 2/5/24, and will look into having it repaired. Is this just a coincidence or is this a defective problem that the manufacturers should address?

The power steering on our 2018 Chevy Colorado fails intermittently during driving.

The key will not come out of the ignition when the vehicle is in park. This presents a safety issue where the driver cannot leave the vehicle because the key is stuck in the ignition. The problem has been reproduced by the dealer and found to be a faulty transmission control assembly. The faulty transmission control assembly has now been replaced twice on my vehicle, once at 19,000 miles and again at 33,000 miles. There were not any warnings or messages, just one day the key won't come out of the ignition.

The beginning of November my driver side door would not open. There was no warning, and nothing happened to cause this. I took it to the dealership. For $161.00 they told me I would need $980.00 worth for parts, which I had to pay upfront, so they would order them. Needless to say there is only one mechanic that is able to do this repair, so I’m still waiting. My appointment is on January 31. I feel this has been a big hazard, do to no fault of my own. I’m just Grateful that [XXX] I can climb through to still use the truck. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When accelerating there is a shake. From diagnostic it seems there is an issue with the torque converter.
