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.
Check-engine light:
Check engine light may come on due to failure of the air/fuel ratio sensor(s). (2005-06)
Check-engine light:
A check engine light, possibly accompanied by drivability concerns, is likely due to a vacuum leak at the intake air control valve on the 3.3L V6 engine. (2004)
Cold-starting problems:
Engine may not start in freezing weather due to fuel pump failure requiring replacement of the pump assembly. (2004-05)
Doors:
The rear hatch door shudders in cold weather due to possible leak in the gas charged support rod (stay). A redesigned support is available. (2004)
Doors:
The doors will not stay open because the welds for the door checks break and the company is extending warranty replacement to 5 years/100,000 miles. (2004-06)
Engine misfire:
Misfires accompanied by the check engine light may be due to problems with one or more of the ignition coils. (2004)
Oil leak:
Fluid may leak past the right side oil seal on the AWD transfer case. (2004-06)
Seat:
If the rear seat won't stay stowed, a revised striker offers more positive engagement. (2004)
Steering problems:
Steering effort increases as corrosion increases on steering column intermediate shaft due to road salt. (2004-06)
Transmission problems:
The transmission gradually gets harder to shift, requiring installation of an improved cable assembly. (2004-05)
