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.
Cruise control:
A voluntary recall was issued to repair problems on some vehicles with the intelligent cruise control when the sensor gets dirty and is fixed by reprogramming the cruise control module. (2006)
Engine noise:
A thumping or ticking noise from under the hood may be eliminated by replacing the fuel system damping hose with a redesigned unit. (2006)
Hard starting:
Engine may not start after a short trip followed by cold soak when the outside temperature is very low (below 10 degrees F) requiring replacement of the intelligent power distribution module. (2006)
