I am having a problem with the steering, brakes, and the heat vent. When turning left or right, it makes this awful noise. When applying the brakes, the steering wheel and the front end begins to shake. I took the vehicle to get the brakes changed and they said the pads look fine. When I had the heater on, it was blowing cold air on the passenger side.

I am having ABS brake problems with this truck. I owned a 2000 Jeep Grand Cherokee for 3 years and had the same problem but it was under warranty. The calipers and rotors had to be replaced 4 times and the truck had less then 30,000 miles. My brake pads were always fine. I traded the truck in early for a 2004 model. The sales man assured me the problem was fixed. After a year, I had the same problem, the rotors and calipers had to be replaced again, and the pads were fine. The mechanic told me the ABS is the problem, as when you step on the brakes, it activates and heats up the rotors and damages the calipers because the ABS brakes do not release in time to cool off the braking system. Chrysler replaced everything because it was under 13,000 miles, but will not if it happens again. Why should we have to pay for a system failure? I think Chrysler should recall all models with this braking failure and fix it. They are very aware of the problem.

Jeep Grand Cherokee. At first, when stepping on the brakes the steering wheel shook. At 14,700 miles and on 6/1/04 the mechanic determined it was only the ABS brakes, and didn't record it. At 20,000 miles and on 12/1 2004 the shaking became worse and they replaced the rear rotors and turned the front rotors at no cost. Currently, the shaking was bad again, and the rotors were too thin to turn. However, all 4 rotors needed to be replaced, the dealer said they would fix the rotors but to never bring it back to them again for this problem. The brake pads have not been replaced because were good.
