Example complaints

“Dt: the contact stated while driving at night applied the right turn signal switch and experienced total loss of the exterior headlights. When disengaging the turn signal switch the headlights came back on. He tested this several times, and each time that he engaged the turn signals the headlights went out, but would come back on when the turn signal switch was not in use. He took the vehicle to the dealer. The dealer could not duplicate the problem. 12/27/05.”
NHTSA complaint #10144121, filed 2005-12, 23,000 miles“Within the last two months, while driving at night on a somewhat crowded interstate, I found myself driving behind a newer model of Cadillac with a new type of tail light/brake light (possibly leds).

I have excellent night vision and use glasses when I drive. I never have light-associated vision problems when driving. …”

The fourth time, the dealer reprogrammed the computer. The fifth time, the dealer test drove the vehicle and found no failure. The sixth and final time, the manufacturer informed the dealer not to take any action. The failure mileage was 8,000 and current mileage was 17,000. …”
