Strange loss of ignition while driving, just for a split second, then ignition returns. Happens mostly during slight right turns, when right turn signal running. Very hard to reproduce, but happens more frequently at night when lights and other electrical on. Mechanic thinks it's in the steering column where ignition wiring and modules are. Haven't fixed it. Just trying to analyze exact cause. Must reproduce at-will to fix. Have to take out steering wheel. Too much hassle at the moment. Will diagnose over time. Car runs pretty much great except for those sporadic loss of ignition like the car goes off the "on" position. Not related to the ignition slot or key. Can pull and push on it with no effect. Not weight pulling key downwards either. Mostly when steering wheel is slightly to the right and right signal running. Very strange. |
| 72000 mi | Very intermittent problem. While driving, getting very short periods of hesitation, total ignition failure and lighting off but ONLY for a split second, then it returns to ignition and all electrical running and keeps going with no issues. Seems like a bad ground issue that only occurs under certain conditions and movement. Gets worse in rain/wet conditions. Very difficult to troubleshoot. Seems like an issue in the steering column/ignition circuit, and generally happens more when the headlights are on. Very short period of single loss of total power, for milliseconds, hesitates and then comes back on like nothing ever happened. I just hope it's not in the ECU or a connector to the ECU. This will take time to troubleshooting. Will post updates. Doesn't happen very often, maybe once a week. Will first have to tighten down all ground wires and go from there. |

| 12000 mi | Original fuel filler cap not sitting properly and triggered a CEL. Fuel filler cap replaced at no charge. |
| 16000 mi | Gas pedal sensor failed, engine would not rev when accelerator was pressed. Since car could not be driven above idle, I had to have it towed the ten miles to the dealer for repairs. Same repair trip as above - Thermostat replaced because of faulty ECU readings. Problem was unrelated to the failed gas pedal sensor. I hate this car and am going to get rid of it at the earliest possible opportunity. |

It had been very cold that morning (-14F) but was 25F when the lights came on. Dealer said code was P2128 (APP sensor) but couldn't replicate, likely caused by the cold. |
| 45000 mi | Same error code as in January 2011 - P2128. I checked the code myself and called the dealer; since the vehicle is out of warranty and I've driven more than 12,000 miles since the last code, they won't fix it under warranty. |
