problem #5

Rear defroster stopped working. Went to dealer for another issue and dealer told me someone put in an inadequate wire to module and caused it to melt. Went to 3 junkyards today and found 6 Alero around the same year that all had the wire melted to the module. Found this online so here I am.. dealer tried to point finger at someone else but its obvious this is an Alero problem. I'll be contacting the dealer again to see what they'll do about it before it causes a fire.

2001 Alero gl had problems with the computer, cruise control, and the floor was leaking.** answer required***. the vehicle consumed excessive amounts of gas, the vehicle only got 208 mile per tank of gas. The rear defroster works intermittently. The ABS light, traction light and service engine light illuminated at the same time. When this happened the vehicle lost traction and ABS brakes. On two occasion this failure caused the consumer to lose control of the vehicle. The rear seat slid forward when the brakes were applied abruptly.
