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:
A/C may make hissing noises and is corrected by adding 90g more refrigerant to the system. (2006)
Air conditioner:
A/C may blow warm air after driving about an hour due to an air leak near the evaporator sensor. (2006)
Check-engine light:
The check engine light may come on and a code for excessive torque converter lockup slip may be stored due to failure of a seal on the converter. (2006)
Interior trim:
The decorative trim on the console heats up when rear seat heat is selected, which can become uncomfortably hot on the driver's knee when contacted. (2006)
Mirrors:
On vehicles equipped with xenon lights, the power mirrors and windows may quit working if a connector behind the headlight gets wet and corrodes. (2006)
Steering problems:
Power steering assist may fade due to internal wear of the power steering pump. (2006)
Water pump:
Overheating can occur if the electric water pump fails, which will fail again unless a very specific bleeding procedure is not followed. (2006-07)
