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:
The A/C fails to operate accompanied by failure of the temperature gauge, transmission-selector light, and the outside-temperature indicator just displays two dashes, but the system returns to normal if the key is switched off and on, requiring replacement of the A/C electronic-control unit. (1998)
Audio system:
If the CD player stops working, but returns to normal when the key is cycled, or the there is cross-talk on the AM band, the company will replace the radio-tuner assembly. (1998)
Electrical problem:
Using the wrong cigar-lighter element (wrong size for the socket) can cause a short circuit. (1998-2000)
Oil consumption:
Excessive oil consumption caused by sludge buildup on the cylinder heads. Company is extending warranty. (1998-01)
