NHTSA Complaint #11619503 — 2023 JEEP WAGONEER

I bought this vehicle used form Carmax, <12000 miles. Drove about 12 miles, when while parking I noticed the car stopped and asked to start engine and engage gear again. Didn't think much of it. Then started driving again and the check engine light turned on. There are lots of reports of wagoneers with engine light problems (in fact we had test driven a different one with both check engine and transmission lights on which for obvious reasons didn't buy). I reported to Carmax. Finished my drive and stayed idle for a while trying to see if there were any settings that may be responsible, but the engine was stuttering, almost shutting off, with the entire thing, even the driving lights shutting off intermittently. The following day I took the vehicle for a check at Carmax, and while slowing at an intersection to let a school bus pass, the car completely shut down. I started again and drove very carefully. They could not diagnose the problem at Carmax and they wanted to send to Jeep. I eventually returned the vehicle. I had seen reports of many problems with the 2022 Wagoneer model, but none about the 2023, but I now came across forums where people even describe complete shutdowns of the vehicle while driving in the highway. While I returned the vehicle, I think these serious engine and system failures could endanger others on the road. I took videos and pictures of the problems. Happy to share if you request them.
