A couple nights ago I started my vehicle and the lights were dim at the dashboard. At the same time the headlights would only turn off when the vehicle was turned off, the turn signals quit working, but the hazards work though, the dome lights didn't work unless lens pushed on but not from turn signal lever and the windshield wipers quit working. This all happened at the same time. I thought maybe a cluster relay was bad. The more I look into it, it may be the tipm is faulty. In the past year I have replaced the battery twice, alternater is good and the vehicle stalled at random times.
This vehicle has an intermittent electrical issue, periodically all of the dashboard warning lights will flash on and then all of the electrical systems will fail - including the speedometer and other instrument gauges, the turn signals and the other lights, the windshield wipers, the radio, and everything else. Usually everything will reset after the vehicle has been parked, shut down, allowed to "rest" for several hours, and restarted. This event has occurred 8 or 9 times since the original incident. After the most recent incident the radio speakers went down one by one and you can no longer use the radio, however you do sometimes get a loud static sound over the speakers - even though the radio is turned off. I contacted the dealership after the original incident and was told that when this failure event occurs the system would "reset itself" without intervention, and that I would have to pay a diagnostic fee if I brought the vehicle in for testing, so I have been putting up with this ever since. However, now that other related systems are failing permanently I am not willing to put up with it any longer, I am concerned that eventually everything else will fail permanently including the instruments, turn signals, windshield wipers, etc. The consumer sent an e-mail requesting to add additional info. Yesterday, 07/21/2011, this vehicle stalled out twice while in operation while my wife was running errands in normal city traffic. In both cases she was able to steer the vehicle to the side of the road using the vehicle's momentum and was she was able to restart the vehicle a short while later. This is the first time that the complaint issue has actually resulted in the vehicle stalling out while in traffic. It is also the first time that the complaint issue has occurred in such rapid succession - for the last couple of years the frequency has been once every 3 or 4 months, now it is becoming once or twice a week (or in this case, in a day). Unable to add the last few lines of consumers sentence as there is a character limit. 07/22/11.
