I'm having continuous issues w/ my "Service Engine Soon" light and my "Charging System" light. The code that I keep getting when I run my diag is P0455. I have checked and replaced the gas cap several times and it keeps coming back. Also the charging light keeps coming on and going off. I have had the system checked and no one can find anything. The car is running fine, but I don't want to take any chances on something bad happening. Can I please get some insight? Thanks!!!
