Components related to timing chain failed, and vehicle is currently available with plans to sell to a salvage yard by 10/25/24. My 9 year old and I were at risk of collision when the vehicle failed. I was driving approximately 70-75 mph when we started to lose power. At 65 mph, I managed to cross 2 lanes of highway traffic and stopped on the shoulder. I turned off my vehicle and waited several minutes, hoping it would help reset or cool off a component or something. I had to try a couple of times before it started, and I attempted to drive as safely as I could, made it to 60 mph before it stopped running completely. I had to pull hard on the steering wheel to get to the shoulder again, only this time, the shoulder was pinched off in front of us and around a small blind spot behind us. I had my daughter move to the side closer to the cement barrier while waiting for a tow truck. She became very nervous about how close some of the other vehicles got. Afterwards, the error codes indicated several components pointing to a timing chain problem. I had the timing chain repaired around April or May of 2023 by a certified mechanic. I watched the oil life percentage and oil temperature gauge consistently. Everything indicated as normal, but I had difficulty pulling out the dipstick to check the oil level. Since it was hard to get a good reading, I tried to add some oil and recheck. The oil cap was nearly impossible to open, so I decided to wait for an oil tech to do it. Around 40-50% oil life, I had planned to have the oil changed. In spite of my efforts to maintain proper oil quality, the oil cap had to be opened with a wrench. Smoke rose out and dried out oil residue lined the inner walls. It was about a quart low. I don’t drive hard on it and it had only been around 3,000 miles between oil changes. It had been one year since the timing chain was replaced. Error codes remain and the vehicle runs rough if it stays on long enough after much effort to start it.

This vehicle is notorious for multiple electrical failures. The alternator fried the battery fried, both of which were replaced. This vehicle still wouldn't start. The wiring harness to the PCM is notorious for having shorts. The pcm itself is notorious for going out really early. This vehicle is almost undrivable and it dies while you're in the middle of driving where you can't stop. I do not know how this vehicle has been kept on the market without being recalled. I do not know how more people haven't been in accidents because of it. And even worse, it's notorious for the airbags messing up. I think I would be more understanding if it weren't for the fact that this vehicle has been well maintained. It has regular maintenance. It's never overdue for an oil change or a fluid top up. I have children that ride in this vehicle and now I have to worry about their safety.

In summary, a business is selling unsafe "sidewall patched" used tire. On Sep 20, 2025 I purchased four used tires for my 2011 Chevy Traverse in this business. Mike's Tires Plano [XXX] ) [XXX] [XXX] Ten days later, one of the tires started to have a slow leak. On Oct 5, 2025, I visited a nearby National Tire & Battery store to have it checked. And was told that the tire is not repairable, since it already had a sidewall patch and the same patch had a leak again. After some research, I found it was illegal to sell and install sidewall patched tires in Texas, since it is unsafe to drive with such tires. (A failed patch on the sidewall dramatically increases the risk of a sudden and catastrophic tire blowout, Most professional tire shops will refuse to repair sidewall damage because of the significant safety risk and liability involved) A common criterion for an unsafe used tire is one that "has a repair to the tire in the tread shoulder, sidewall, bead area or belt edge area." On Oct 6, 2025, I went to the tire shop to ask for a refund or to replace other safer used tires. But the owner refused to do any, and even refused to admit that his tire is a sidewall patched tire, saying it is safe to use and legal to sell. I am writing this letter to complain that this business unlawful and unethical practice puts people's lives in danger. Texas Transportation Code Sec. 547.612 [XXX] “(f) Except as otherwise provided by this subsection, a person who owns or operates a business that installs tires on motor vehicles or an employee of the person may not knowingly install an unsafe tire on a motor vehicle to be used on a public street or highway.” INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

side curtain airbags deployed driving 70 mph on I94 outside of Monticello, MN after drifting onto the rumble strip. Upon turning back there was a loud bang from the side airbags deploying. The drivers side came down and hit my daughter in the side of the head, the passenger side didn't come down all the way missing my 86 year old Mom as she is 5 ft tall. My daugther by some miracle didn't panic and veer into other traffic lanes with other vehicles driving 70 mph. GM is denying a problem and insinuating that something other than defect caused the airbags to deploy, even though there is nothing but rumble strips on the section of road. They are blaming some minor scraps on the side of the vehicle that were existing on a 2011 Traverse.
