Just over 31k miles. The typical warning lights came on but drove fine. First It happened this winter and then early summer. Since it didn't threw the vehicle into limp mode, I disconnected the battery to reset the ecu both times. The lights were off til it came on again for the 3rd time. Left it and took it to dealer. Only thing I noticed before the warning lights came on was a noticeable loss of engine power and less throttle response.
