Picked up the Acadia tonight with mixed results.
#1) The black trim rings look good, as expected. I'll post pictures tomorrow.
#2) Customer states the driver seat moves when braking.
Diagnosis: Verified concern and found Document #2757018 to install anti squeak shim. Installed shim kit per document.
Result: The seat moves more now. Just about every stop, and every start now I can feel it move. I'm going to have to bring it back for this.
#3) Customer states there is a squeak in the steering wheel when turning.
Diagnosis:Diagnosed and verified concern. Found Document 2807958 to replaced power steering gear housing for noise. Replaced steering gear housing, hose and bolts and rechecked.
Result: This one seems fixed. It is not making the noise when I turn the wheel anymore. I will double check tomorrow to make sure there aren't any leaks or anything.
#4) Customer states that trans is shifting hard, downshifts hard. Please check.
Diagnosis: Test drove vehicle - checked for updates - no updates now
Result: I didn't expect them to find anything here, but that is NOT how I described the problem. The problem is it holds gears too long and downshifts too early/much.
So I will have to take it back for the driver's seat problem. I had read posts here about this, and seen the shim fix, but mine is now worse. On the plus side, now that the trim rings have been replaced I can get to work on relocating the USB port into the center console.
Thank you for sharing. I can understand how disheartening it must have been to feel your seat move more than when you took the Acadia into them. Please, let me know how your next visit goes with them. After getting that information, I will be able to know what steps we will need to take next to get you to enjoying your Denali again.
