“On 9/27/2006 around 8:45 pm (dark) just north of payson, az on az hwy 260, I stopped for an accident blocking a narrow part of the road and turned on the hazard flashers on my 2001 Gmc Sonoma. After a short period of time (2-3 min.) the hazard lights just quit flashing. I also lost my turn signals and brake lights. I visited a dealer in show low, az who diagnosed the problem & gave est. Of $400-$500 but could not repair (part not in stock). …”

“While driving passenger's side headlight fixture sheared off. This caused poor visibility for the driver. Consumer drove vehicle to the dealer, and mechanic advised consumer that the warranty expired, and consumer had to pay for the part.”

NHTSA complaint #10092859, filed 2004-09

“Nearly been involved in numerous intersection accidents. Driving lights stay on all the time, except when turn signal enabled. The flash makes it appear to other drivers as if I were signaling them to take the right of way.”

NHTSA complaint #742881, filed 2001-03

“To date, there have been only near incidents & near crashes, with no injuries. The problem on these vehicles, as well as the chevrolet copycats, is that when the turn signal is applied during the day, the headlights shut off until the turn signal is shut off itself. This creates a grave safety hazard that inadvertently signals other drivers around you when you are making a turn. I have brought this to the attention of the service dept. Of the dealership the vehicle was purchased from, on several occasions, only to be told each time that it is normal for the vehicle make. …”
