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.
Audio system:
When using a portable music player (e.g. iPod) there may be noise in the car's speakers whenever the vehicle's power adapter is used and a ground loop isolator (from Radio Shack) is required between the device and the power outlet to prevent the noise. (2007-08)

Check-engine light:
The check engine light may occasionally come on during light acceleration due to a damaged torque converter O-ring. (2007-08)
Electrical problem:
The power locks, cruise control, shift interlock and other accessories may not work; the engine may not go over 4,000 rpm and the check engine light may come on in cool temperatures (32-50 degrees F) after cold soak due to a problem with the transmission control module. (2007)
Fuel gauge:
If the fuel gauge shows low, but there is fuel in the tank, reprogramming is required. (2007)
Oil leak:
The oil pressure switch may leak which shows up in the neighborhood of the starter. (2007)
Water leak:
Water may leak onto the headliner near the sunroof switch due to the sunroof going out of adjustment and the sunroof trim (bezel) may come also loose. (2007-08)
