In owners' own words
The anti theft system caused the engine to quit going down the hi way several times and was very dangerous some of the times and left us stranded sometimes. Gm acts like they do not know what is wrong but there is ample info on the internet and even a fix but it disable the ats, it turns off the fuel to the injectors killing the engine. This happened many times. We had to be towed twice because it would not restart. Electrical system · reported at 190,000 miles

I have a 2003 Chevrolet suburban that the speedometer has quit working in. Chevrolet refuses to take care of the problem. I have researched this online and found many others having the same problem, some have even filed lawsuits. This item is extremely costly and I can not afford to replace it, nor do I feel that I should. I think the manufacturer should recall them and take care of the problem. Electrical system
