2005 Tahoe memory seating issues.

[99-LS1-SS]

I've posted this on a few boards in hopes that I find an answer.

I have a 2005 Tahoe and the memory seating works about 75-80% of the time. When it doesn't work it doesn't go back to the set position. It can even go the opposite way that it is supposed to by pushing you closer to the steering wheel. I've taken it to the dealership and they say the can't reproduce the issue and can't find anything wrong with it. Does anyone on here know anything about these seats?

Thanks.

Supercede:

This bulletin is being revised to update the correction information. Please discard Corporate Bulletin Number 04-08-50-016B (Section 08 - Body and Accessories).

Condition

Some customers may comment that with repeated cycling of the memory seat between the "exit" and one of the "presets", the position of the seat may "creep" forward or rearward out of expected adjustment.

Cause

There is a coding deficiency in the software for the memory seat module.

Correction

Technicians are to reprogram the driver seat module with an updated software calibration. The previous bulletin stated to use a service calibration that was released with TIS satellite data update version 4.5. Feedback has proved that calibration to be ineffective in eliminating the memory seat creep condition. An updated service calibration was released with TIS satellite data update version 6.5 available June 13, 2005. This new calibration has additional memory seat creep protection. As always, make sure your Tech 2(R) is updated with the latest software version.

Important: After programming is complete, move the seat all the way rearward and down, then bump the seat slightly forward and up. This position will be just off the end of travel hard stops. Reset both memory seat exit positions at this position. Having the seat set at just off the hard stops will aid in reducing the creep condition.
