What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The car was parked with engine running and parking brake on. I released the brake on and the car lurched forward crossing a curb and hitting a aluminum guard rail. The service seq transmisame light came on . After being towed to the dealer. It was found a hydraulic line had broken from corroding.
While driving approximately 25 mph, the vehicle stalled and the steering and gears seized. The vehicle was pushed to the side of the road and towed to the contact's residence. The manufacturer was not notified of the failure. The vehicle was not repaired. The vin was invalid. The approximate failure mileage was 41,500.

But the vehicle operator's manual anticipates stalling while underway and gives directions to re-start - sometimes successful, sometimes not and the vehicle…
Purchased used from carmax and within 100 miles the transmission light came on, it would not shift out of first gear. I had it delivered to have the vehicle looked at, and it refused to go into reverse gear next. When they attempted to drive it only 1 st and 2nd gear would work.
