On vehicles with the tire pressure monitoring systems (TPMS), the warning light may stay on due to a software issue with the tire pressure monitor control unit. There is updated control module software available from the dealer to correct this concern. In some cases, the control module and/or other parts of the TPMS may also need replacement. You should always check your tire pressures when you see this warning light, including the spare tire.
Proper tire inflation is critical to the safe operation of all vehicles. Tire pressure specifications can be found on an inflation sticker on the driver's door frame or in the owners manual. Fuel mileage, increased tire wear, ride quality, handling, and road noise are just a few of the problems that might arise from improperly inflated tires.
All models up to 2007 with cast aluminum wheels may experience a loss of air pressure that is due to porosity in the aluminum casting. Have your repair shop refer to GM SB-05-03-10-003B for instructions on how to repair this problem.

If your steering wheel is off center or you hear a clunking noise while turning, it may be due to a loose inner tie rod end. To correct this fault, the inner tie rod ends should be checked and properly torqued to GM specs. After the tie rod ends are secure, the front end alignment should be checked (SB-07-02-32-008A).
If the spare tire will not lower, it may be stuck to the frame. Lightly prying on the spare tire will break it loose, allowing it to be lowered to the ground.
If your van is experiencing abnormal tire wear, it may be due to a worn out idler arm, pitman arm, or center link in the front suspension. Worn parts should be replaced and the suspension aligned.
