Engine Noise problems of the 2002 Chevrolet Trailblazer

I was simply trying to clean my windshield with the wiper blades. When I flicked the switch the car shut off. I immediately got over and turned truck back on. A couple days later I was leaving out for work when I tried to start the car, it stalled and I heard a hissing noise. I couldn't get it to turn over or make any noise other than hissing. The speedometer started moving back and forth erotically. The radio and power windows works but the engine would not turn over. I had it towed to my repair man and he told me there was a electric problem and to call the gm dealership for further assistance. The truck will not start up. There is a short. It shuts off constantly while driving and sometimes I have to push it to avoid oncoming traffic. It won't sped up past 60 without troubling the transmission. While driving sometimes the speedometer doesn't work at all or it jumps,around without reading my correct speed. When I try turn signals it cuts off. When I turn my lights on and off it hisses. Something has to be done. Its my only means of transportation and I really need to find a solution.

I received a letter stating that my "2002 Chevrolet Trailblazer may experience a cracking of an engine cylinder bore liner. This will cause engine noise, poor performance and/or stalls with no engine re-start. This is not a recall. Do not take your vehicle has the condition as described above". I feel that this is irresponsible by Chevrolet and the action they are taking is also irresponsible. They are covering the vehicle for 7 years or 100,000 miles. Please look into this and make Chevrolet correct the problem. If they know they are putting a faulty product on the market they should be responsible enough to correct the problem. Nestor valle .
