2 Turn Signal problem of the 1998 GMC Sonoma

Failure Date: 02/01/2009

I have not had any wrecks or anything like that, yet. My turn signals don't work properly one of my low been headlights keeps blowing and my taillights don't work. I have changed the bulbs just for them to blow when I test them. And no I do not touch the glass on the headlights. I seen there was a recall on the lighting system and on the wiring system, could this be my problem?.

3 Turn Signal problem of the 2002 GMC Sonoma

Failure Date: 10/24/2005

Check engine light on was told air injector valve oper/solenoid replace. Drove 800 miles, took emissions test failed. Showed no codes. Was told by tech to try driving 100 miles. Or take to dealer, took to dealership charged diagnostic fee. Was told by them to drive 100 miles. Drove 150 returned next day. Still the codes are not showing. Want me to drive another 150 miles. Two codes are not showing. Took back to emissions provider, they showed me it was the 02 sensor and last test on the obd computer. I don't remember the name. Also please note my radio froze again playing on 1 station and showing another. Showed it to tech today. And also my brakes still giving same problem. Abs brakes still pulling vehicle. Bought new tires to help with the traction. But problem still same. Fuel was about 12 miles per gal. How many miles do I have to drive in order for the computer on the vehicle to respond. I've driven over 1000 (one thousand) since Friday 10-21-05. What a lemon! I will be returning back to the dealership (chev) tomorrow after driving 150 miles. My daytime light still goes out when using turn signals.

The headlight blinkers are not functioning. They called gm, and they said it was not a recall. They felt that this was a safety issue. The gas tank gauge went out. The dealer stated that this was normal and would not fix it.

5 Turn Signal problem of the 2001 GMC Sonoma

Failure Date: 07/06/2004

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. I would like the manufacturer themselves to be aware of this situation, as if I am ever in an accident as a result of the above mentioned situation, I will not only sue the manufacturer & dealer, but the NHTSA also, for failing to issue a recall. It should not take an injury or fatality to correct a potentially serious situation as this most definitely is.
