SO a few days ago my Overhead panel started reporitng that the temp was 148 degrees. About an hour later the check engine light and the battery light went on. Unfortunately I was forced to drive the car from Washington DC to NorthCarolina then up to New Yourk City. The trip was fine and i had absolutely no problems. I took the car in and the mechanic called today and said my BCM needed to be replaced at a cost of $640. Anyone have any advice onthe topic???
