2018 Chevrolet Colorado

At approximately 6:15am while driving at approx 45MPH on a surface street on the right lane, I noticed an alert on the dashboard regarding the PSI of the rear driver side tire had 0 PSI of pressure and simultaneously heard the thudding sounds of a flat tire. I neither heard, nor felt any impact and there were no potholes in that section of road. I pulled over and called for roadside assistance to replace the tire with my spare. I noticed a large tear from the tread nearly all the way down to the bead along the wall of the tire. Tire M+S 255/65 R17 110T. When the tech arrived he noted the tire was new (purchase and installed 42 days earlier). I asked if he's seen this before as I hadn't, and he said he'd only seen it when a driver hit a curb, which I had not. In the early evening I took the tire back to the shop where it was purchased and before even looking at the tire they informed me I "must have hit something" and will just need to purchase a replacement. After they inspected the tire at my insistence, they concluded I must've hit something but I believe it was a case of confirmation bias. I pointed out, and they did not refute, that there was no other damage to the tire, no damage to the rim, and no damage to the vehicle. The subject tire is still in my possession and available for inspection.

The vehicle stuttered upon acceleration between 20mph and 35mph. After the 2018 Chevy Colorado was taken into the Chevy dealership for inspection, the torque converter failed at roughly 76,000 miles. A bad torque converter can potentially cause an accident. It can lead to engine revving issues, sudden speed changes, which can be dangerous while driving. The torque converter failed and left metal shavings in the transmission causing the transmission to need replaced as well. This was diagnosed by the Chevy dealership and has a repair ticket of over thirteen thousand dollars. ( $13,000.00 ) which most people can't afford to absorb. After a quick Google search, this appears to be a common problem. There should be a recall to fix this issue.

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.

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?
