Climbed into mine on Sunday to take it to the store. Had not driven it since I got it back for 245A code. Anyhow no start! Dead battery? HUMMMM Put the charger on it and a few hours later it starts right up. So off I go for a drive and the CEL is on AGAIN! Dropped it at the dealer and he tells me that one of the batteries has a bad cell. Oh well new battery and a new radio finally. Two CEL's within 100 miles has me worried too.
