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: Model 700-R4 automatic transmissions may shift late or not upshift at all. The problem is a stuck throttle valve inside the transmission. (All years)
Engine noise: The exhaust valves on the 5.0- and 5.7-liter engines may not get enough lubrication causing a variety of noises. Usually, the same engine consumes excess oil because the valve-guide seals on the exhaust valves are bad and have to be replaced. (1994-96)
Steering noise: The upper bearing mount in the steering column can get loose and cause a clicking that can be both heard and felt, requiring a new bearing spring and turn-signal cancel cam. (1994-96)

NHTSA Recall History
1991-92: Secondary hood-latch assembly can corrode, causing high latch release effort and possibly preventing hood from latching properly.

1992: Antilock brake system modulator can corrode and leak fluid; can reduce brake effectiveness and increase stopping distance.
1994: Fuel-tank fasteners can detach, eventually allowing tank to sag and strike roadway.
1994: Oil cooler inlet hose may be too close to steering gear, causing chafing; could result in oil leakage and fire.
1994: On a few cars, paint between wheel and brake rotor/drum can cause lug nut to loosen.
