would a leaky rear wheel axle cause it to not start,when i changed tires i saw that problem
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.
On vehicles equipped with "run flat" tires, the tires can be driven with zero air pressure at up to 55mph for 100 miles. The tire pressure monitoring system will inform the driver of a low tire. When new tires are installed on a vehicle that came with run flat tires, the new tires should also be run flats. These vehicles do not have a spare tire.
All Models Up to 2007
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.
All 2008–2009 Cadillac Models
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.
Cadillac SUVs and Trucks 2007–2009
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.
In cold climates where snow is significant, it may be advisable to change to specialized winter tires. Please refer to Pontiac SB-04-03-10-013C regarding this issue.
If you are 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.
Due to an internal fault with the tire pressure monitor control unit, the tire pressure monitor message might come on. It is recommend to replace the control unit, its antenna, and the door lock remotes to correct this concern (SB-07-08-52-001B). The 2007 Escalade had a similar issue that was due to the software and/or the module (SB-06-08-52-002G). You should always check your tire pressures when you see this warning light, including the spare tire.
If your CTS-V has Michelin Pilot Sport PS2 tires, you may experience “popping” or “clunking” sounds when backing up with the steering wheel all the way to one side. This is a normal sound from the tires as described in SB-08-03-10-013.
