Last year, the engine stopped while driving. Dealer replaced cpu and told me rats caused the damage. Now, service engine light turns on. Searching on the internet showed that the engine control module that is mounted under the wiper gets wet, becomes corroded, and the car looses control. Who knows what is going to happen next.
