Engine & cooling

My engine malfunctioned after the module under the back seat was wet from an unknown water leak in the vehicle. My vehicle lost power without warning until I came to a complete stop on the side of a very busy highway. I'm not sure if the repair center kept the faulty module or not I would have to check. I know leaks have been a problem with my model in previous years but when I checked my VIN there were no recalls. This is a very dangerous defect and should be fixed.

I was pulling into shopping center all dashboard light up warnings etc. Started to head home because of prior incident with computer failure. Car stopped mid intersection and went dead. Put it in park restarted and drove home. Headlights and electrical engine would not shut off. Called service to tow to dealership repair. Tow truck driver attempted to turn of lights, no luck. Car repaired at dealership, was told at that point of a possible recall, but they didn't know of what. Car repaired. As soon a lease is up it is gone! *Tr
