2 Dash Wiring problem of the 2002 GMC Sonoma

Failure Date: 03/29/2004

Problem-electrical- radio replacement, third radio place I am on my third radio. The first radio began to frequently change stations on it's own. I thought it was satellites, towers, and didnt think much of it in the beginning. It was noticed by my daughter as having a life of it's own. Then it started to change often, while displaying another channel. It was replaced by dealer. Second radio- display window began to blink, flashing the channel numbers. It was changed by dealer third radio-changed stations once so far. Not a noticeable incident yet. Have not complained yet. In all radios, the panel gets very warm incident date is last repair date.

3 Dash Wiring problem of the 1996 GMC Sonoma

Failure Date: 02/11/2000

There are numerous, substantial safety hazards to these vehicles which appear to be common knowledge to mechanics but denied by dealerships. The ball joints are apparently common failures according to massachusetts safety inspectors and are deemed to be an extreme safety hazard. They state that dealerships regularly deny any responsibility for this failure. My vehicle is extremely well cared for, not abused in any way, and has experienced defects, which in my opinion demonstrate gross negligence on the part of GMC's engineering/production. I am also a professional engineer, and prepared to testify the same.
