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.
Automatic transmission:
The transmission may not shift out of park due to failure of the key lock control module. (2006)
Automatic transmission:
Automatic transmission may not operate in drive or reverse due to the maladjustment of the transmission range shift and could ultimately lead to complete transmission failure. (2006)
Gauges:
The displayed temperature may be off from 5-10 degrees from actual outside temperature, on vehicles with the fully automatic temperature control, requiring replacement of the temperature sensor. (2006)
