While driving with both of my children in the rain my entire car locked and my windshield wipes stopped my windows wouldn't roll down and my doors locked on and off my alarm system started to go off uncontrollably even while driving Porsche isn't being of any help giving me run arounds also my check engine light came on in the process of the incident.
This vehicle allows you to be locked inside. After driving if the driver and passenger open their doors then the lock button is hit on the key (while the doors are still open), then the doors are closed anyone inside in unable to unlock any doors, even when hitting the unlock button inside the vehicle located on the door. This is a huge safety concern.
While driving I heard a loud knocking noise and comming from under the center console and my truck started to shake. I came to a complete stop then proceeded on but once the truck got over 20mph the knocking noise started again .
Its seems to be transmission is slips into four wheels drive, sometime it stuck in a drive gear.
