29 Error Codes. Took five months to get check engine light to remain off and pass emissions test required by North Carolina. Replaced all four O2 sensors, catalytic converter, various relays and finally after receiving only eight error codes it went off on its own after about three weeks. Nothing else was done after the last check that had eight error codes except conducting diagnostics repeatedly over the three week period. Now at 111,000 it's showing errors again. Replaced O2 Sensors and still getting error codes. Dealer service department said they could change out the PCM but couldn't promise it will help.
Check engine light on and nothing wrong also key won't start the car.
