Brake Antilock Wheel Speed Sensor problems of the 2002 Chevrolet Venture

Chevy Venture 2002 w/83732 miles. To whom it may concern: anti-lock-abs light, intermittent abs indicator light. Started having issues with the anti-lock brakes system, when issue started the abs light indicator light would intermittently flash and the abs would by itself tried to engaged while car was running. This made driving the vehicle very dangerous because the abs would try to engage while running not braking. On may 2, 2002, I took the van to local dealership to have it diagnosed for the abs light on. They detected a left rear defective speed sensor and they advised me to have it repair for a total cost of $741. 00 which I declined. I then called gm to inquire about any service bulletins and/or recalls on my minivan, gm found none and they declined to assist with this repair. Glen at gm stated that the defective speed sensor had failed because of the age of the vehicle and the driving environment where vehicle is driven (illinois=snow=salt=corrosion). I do feel that there is a defective part within the abs braking system and to be more specifically, the speed sensor. I will not be buying another gm product. I would be very happy to see a safety recall on this issue. Thank you very much for your assistance in this matter. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.

Last year I took my Venture into the dealer to have it looked over because the check engine light was on, all of a sudden I had 3 lights on. I had no traction control or abs. After having the service dept. Look at my vehicle, I was told it was a sensor in the left rear wheel. Since I have discovered that other owners have had similar problems, I think gm should get involved. The part was extremely expensive so I've had to go without for the last year.
