This vehicle breaks failed on me while driving a very known issue on previous year
While parked and running with no driver in the vehicle, the vehicles key fob was locked in the car by a passenger exiting the vehicle. the passenger, a child, exited the vehicle and pushed the "door lock" button and then closed the door, locking it while running with the key fob in the vehicle. no warning alert noise was emitted and the vehicle did not automatically unlock the doors as designed. the weather was approx. 80 degrees. this hazard is not suppose to occur and poses a high risk of causing harm or death to an unsuspecting passenger. the hazard mitigation for this event failed.
While driving, the check engine light intermittently flashes. vehicle runs extremely rough, sluggish at times. dealer checked vehicle over a period of time and eventually confirmed random misfires. unable to fix issue. unable to determine cause. vehicle was later confirmed to have a faulty transmission transmission replaced by dealer.
