2018 Traverse. 70k miles. We purchased it brand new at the end of 2017. On [XXX], we were driving home from Michigan the car sputtered and would not accelerate. We were almost hit by a semi that was driving behind us. We were able to pull into a gas station and put the car in park. While sitting at gas station the car shut off and wouldn’t restart. No warning lights came on prior to the vehicle shutting down. We had it towed to our mechanic (VIP Automotive- New Lenox, Illinois). The mechanic went through the car and advised that the engine had seized. All fluid levels were fine, no leaks, all scheduled maintenance completed on time. He found metal chunks- not just shavings- in the oil pan. He said he’s never seen anything like this and that the catastrophic engine failure had to be due to a defect in the engine. It ended up costing us almost $6,000 to have another motor installed in the car. I contacted Chevy, and was basically told too bad, and that they would not cover or assist with anything. The car was extremely well maintained and I provided a copy of all service records dating back to 2017 when we purchased the car. There are numerous groups on Facebook that have same/similar complaints on the Chevy Traverse (3.6L V6) and Chevy Trucks/SUVs (6.2L V8). I believe they are aware that there are numerous issues with these vehicles and continue to sell them, despite the risk to consumer safety.
