Trouble Spots
Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search
for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested
solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer,
however, we have our own expert looking at additional vehicle problems.
Air conditioner:
The HVAC system mode switch gets stuck in the vent position as oil gets into the control head as a result of a leaking vacuum switch on the transfer case and a redesigned switch is available. (2001-03)
Electrical problem:
The radio station presets and the climate control settings may suddenly change because the memory buttons on the driver's door gets bumped easily requiring reprogramming the body control computer to prevent memory changes when the vehicle is in gear. (2002)
Engine mounts:
Cylinder liners were cracking on 4.2-liter engines and the engine warranty was extended to 7 years/100,000 miles. (2002)
Ignition switch:
Transmission may get stuck in third gear and the instruments panel may stop working due to failure of the ignition switch. (2002-03)
Keyless entry:
If the remote keyless entry quits working in warm weather, the liftgate module must be reprogrammed. (2002-03)
