NHTSA Complaint #11618746 — 2011 CHEVROLET TRAVERSE

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.
