Worried about potential repair costs? An extended warranty can provide peace of mind.
Chart based on 227 repair trips. The repair cost chart excludes repairs made under warranty, do-it-yourself repairs, and repair trips that include maintenance.
A couple of weeks ago, I cranked it up and it was idling very rough. I shut off the engine, then restarted it. It seemed to smooth out, but it threw a CEL. Went to the dealer the following day, and the codes showed a lean fuel trim condition in both cylinder banks (PO171 and PO174). The fix was to replace the solenoid for the evaporative canister purge valve. Warranty covered it, and all is good.
