Who knows the best about this car? What should concern me the most?

While driving my car this light comes on sometimes,and my car turns off in the middle of the street and all of the lights on the panel go crazy. Already changed the module and fuse box. No codes come up when we took it to the mechanic at the dealer. Only advice given from the mechanic is to wait ...

The one time I have had the code checked it seemed to be a heating thermostat. The engine is running cooler since I had the coolant reservoir elbows replaced with aluminum units rather than plastic.

Engine oil may leak from the valve cover area, which can cause a burning odor and increase risk of fire. Dealers will replace the spark plug wire retainer to redirect the dripping oil on affected vehicles, and will replace the left valve cover gasket on vehicles with the 3.8L V6 supercharged engine.
