Open the full vehicle complaint log (all categories)Vehicle died in parking lot. The electronics all worked, it just would not start and would not go into any gear. Had to have it towed to dealer for repair. They replaced the PCM but it still would not start. They again replaced the PCM and a fuse. The vehicle started. This is the FOURTH time for the exact same issue. It died twice on the previous owner, once while on the highway. It also died twice for the mechanic while trying to diagnose / test drive the unit for the previous owner. We were lucky it died where it could be towed as it's an all wheel drive unit. It has also had an O2 sensor replaced, and the previous owner suffered wiring issues (replaced the engine bay body harness), sunshade recoil failed, abnormal noise in rear end when turning, etc. All issues were corrected. However, I am uncomfortable that these issues may re-occur. Another failure of the PCM and/or electrical issue could cause the unit to die in a situation that could be life threatening.
Since 2023 there has been an ongoing issue with my vehicle. When Im in public parking lots and I am accessing the trunk. I’ve witnessed my trunk literally shutting down or closing as Im accessing the trunk. Ive recorded this safety concern and Ive reported it to the dealership and manufacturer. The last time this serious issue occurred was last Friday, May 9, 2025. I was loading the trunk with my purchases as the trunk began closing. Whatever is causing this to occur. Ive noticed that the safety feature that signals the trunk to stop closing when it detects an object in the way becomes disabled. The trunk does not stop closing when Im underneath it. Ive witnessed my trunk sporadically closing at least four to five times on Friday. I was able to record one time that it closed as I said it kept happening sporadically. On the same day, I called the dealership and left a message with one of the contact people. As of today, May 13, 2025. I haven’t not gotten a response. This is a safety and security issue that needs to not only be addressed but resolved. And I am not getting help with either of the two.
