“Recall 24S55/24V635 was issued in October 2024, the issue with intake valves was discovered prior to October 2021. My car was manufactured in July 2021 within the time of inefficient intake valves. The problem continues to exist as there is no remedy. No remedy and no problem dealer won't look at the car, (even with a clicking noise) I don't drive it with concern my engine will quit in the middle of the road and I could be 500 miles from home. It actually has to stop dead in the middle of the road to be looked at. I can't trade it because it's under recall. It's a catch 22. …”

“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. …”
