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 A/C performance may gradually get worse and airflow from the vents may decrease after driving 1.5 hours because the evaporator ices up. A wiring harness adapter will fix the problem. (2004)
Check-engine light:
The check engine light may come on due to a vacuum leak allowing air past the pivot for the intake air control valve. (2004)
Engine stalling:
The engine may not start in below-freezing (32F) temperatures, requiring a revised fuel pump sub-tank assembly.
Transmission leak:
Transmission fluid may leak from the oil seal on the right side of the transfer case for which an improved oil seal is available. (2004-06)
Trunk latch:
The automatic rear hatch may begin opening then reverse and close due to weak gas support struts. (2005-06)
Windows:
If the automatic up function for the window quits, the switch must be replaced with a revised one. (2004)
