Heated clunking seat

tjaudet829 · November 28, 2016

I have a 2015 GMC Sierra Denali that I have been experienceing some things I have read about on this forum.

I too have had the clunking or shifting of the seat bed.

I aslo have a problem with the heated seat. Most times if I use the bottom and lumbar selection only the seat bottom gets warm.

The back or lumbar does not get warm. I have had to the dealer on a couple of occations and of course they say they did not recreate the condition.

It seams if i cycle through the heated seat and cooled seat a few times i can get the lumbar to come on.

I find this completely unacceptable for a $55k truck.
