I leased car 2020 Illinois. No problems. I had car transported to in 2022 to Los Angeles, and after a few months, the car would check engine light ALL lights I believe, and car suddenly stops and dies out at each stop light. This happened 3 times and frightened me. It happened every couple months and the repair people NEVER put notes on the repair invoice!! About exactly why I was bringing car in for repair, even if nothing on computer showed up, almost like the defect was bypassing (tricking computer) inspection. Have to restart and it would lost all power seconds later and on rainy days, passenger floor soaked. NOTHING on repair places nor dealership would show any problem to fix?? However, when brought back to Illinois, no problem with car, so far since January. So car did not like California OR their emission gasoline no good. …
