Known Problems

Due to a lack of lubrication, the AC compressor can fail. The AC compressor warranty was extended to seven years or 70,000 miles.

If the HVAC (heater) housing is not properly sealed at the bulkhead (firewall), water can leak into the passenger compartment. Foam sealant should be used to seal any gaps and the evaporator drain tube can be modified to prevent further water entry.

If a shudder is felt while turning the vehicle at low speeds, replacing the power steering hoses with revised hoses may be necessary. Also consider installing a finned power steering cooler.

Hood misalignment, cowl cover misalignment, wiper module drain tube(s), and/or the lower plenum drain hose may cause the HVAC housing to leak water onto the passenger side floor. Diagnoses will be required to confirm the location of a water leak in the front passenger area.

The speedometer may become inoperative due to a failed vehicle speed sensor (VSS), . A failed sensor will require replacement.

If the transmission is slipping in first gear or Reverse—or if you experience delayed or loss of gear engagement after initial startup—the transmission may require removal and disassembly.

If you experience a harsh downshift from fourth to third gear, the transmission control module (TCM) software should be checked and updated if necessary before any other repairs are performed.

While turning in either direction during low speed parking lot maneuvers, if a creaking, squawking, squeaking, grinding, or groaning sound is heard from the front strut area, locate the front strut dust boot and rotate the dust boot side to side. If the sound is present, applying lubricant to the jounce bumper (bump stop) of both front struts can help with the noise.

A moaning or fog horn sound may be heard while turning at a slow speed. Installing a finned power steering cooler will help alleviate the problem, but it may be necessary to replace the power steering rack.

If you experience delayed or loss of gear engagement after initial startup, the transmission may require removal and disassembly.
If the horn starts honking and the parking lights flash as if the alarm has been set off—and the vehicle is not equipped with the security system—reprogramming the front control module (FCM) with new software typically solves the problem.
