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.
Climate control:
The temperature in the cabin may be warmer or cooler than the set temperature requiring adjustment of the sun sensor. (2006)
Doors:
The power tailgate may reverse directions when closing due to a loose bolt for the gas strut. (2006)
None:
The integrated garage door opener may resist programming unless the current program is erased, but the instructions may not be in the owner's manual to press and hold the two outer transmitter buttons until the signal light flashes rapidly. (2006)
Seat:
The heated front seats may quit working due to failure of the signal acquisition module. (2006)
Steering noise:
The steering shaft bearing may wear causing noises when turning. (2006)
Suspension problems:
Numerous warnings about the suspension and brakes may be due to abrasion of the wires for the front wheel speed sensors. (2006)
Transmission problems:
Harsh downshifts from second to first when braking may require a software upgrade, a revised valve body or both. (2006)
Vehicle noise:
Noises (squeaks, grunts) from the rear end are due to design of the spring seats and revised units are available. (2006)
