These are from the June GM Tech Link Update

"Low or Completely Discharged Battery Owners of some 2004-05 Cadillac XLRs and 2005 Chevrolet Corvettes may comment that the battery has a low charge or is completely discharged at times.
If a cause can not be located with normal diagnosis, check with the customer or the sales department to determine if the vehicle is equipped with an aftermarket security system. These systems use a small transmitter or GPS locator that is hidden in the vehicle and is usually unknown to the technician. The transmitter is typically installed in the hot-at-all-times dome lamp circuit and prevents the Body Control Module (BCM) from entering the sleep mode."
"Tire Mounting and Dismounting
This information applies to the 2000--05 Cadillac Deville, Seville, STS, 2004--05 Cadillac CTS, Escalade, SRX, XLR, 1999--2005 Chevrolet Corvette, 2004--05 Chevrolet Tahoe, Suburban, 2004--05 GMC Yukon, Yukon XL.
When dismounting and mounting tires, be careful when breaking the bead loose from the wheel rim (fig. 11 and 12).
If the tire machine's bead breaking fixture is positioned too close to the TPM sensor, or pressed down directly on top of it, it may contact the sensor as the tire bead breaks away from the wheel rim. This can damage the TPM sensor and require the sensor to be replaced.
Also be careful when transferring the tire bead to the other side of the wheel rim. As the tire machine rotates and the tire bead is stretched around the wheel rim, the bead can come in contact with the sensor. This can also cause sensor damage, requiring replacement. Damage can be avoided by correctly positioning the wheel and tire in relation to the mounting/dismounting head.
Tire Dismounting Tips
Refer to SI -- Tire Mounting and Dismounting section for more information.
- Place the sensor's cap and valve on a dry, clean surface after removal. The cap is aluminum and the valve is nickel-plated to prevent corrosion. Do not substitute a cap made of any other material.
- When separating the tire bead from the wheel, position the bead breaking fixture 90° from the valve stem.
- Position the mounting/dismounting head so the tire iron or pry bar can be inserted slightly clockwise of the sensor body when prying the tire bead up and over the mounting/dismounting head.
- Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the outside of the wheel rim.
Tire Mounting
- Position the mounting/dismounting head 180° from the valve stem.
- Position the bead transition area 45° counterclockwise of the valve stem.
- Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim."

Yep, thanks for the info.
I don't look forward to having the tires changed.
