drove a rental Cadillac and the headrests did the same thing. Very uncomfortable.

That's so funny how you stated that you "want to pretend you like your car"! BECAUSE I DID THE SAME THING! I would get into and think...OK, I like this car..it's a pretty car. etc.....Then, in about 2 miles as the car is search for gears and speed, I'm suddenly swearing again.
After taking to the dealer last week, they keep the car for 2 days, said nothing was wrong with it.....as usual. About the exact same time I was referred to a Consumers Law Firm by my lease broker who does not refer lightly, and I forwarded all my documentation from all the visits to the dealer. The firm called back saying that "yes" I have a case.
I took the car to yet another dealer the very next day, which is located far from my home, thinking a different dealer may observe something different. Where as my local dealer said at pick up that no recent "updates" were available for acceleration at this time, so none were installed. The more distant dealer said that there were recent updates about 3 months ago specifically for acceleration, which completely contridicted what I was told by the previous dealer. So, it was interesting to witness the different service practices between the two dealers. Lets see how the car does when I get it back. But I have already put the legal wheel in motion. It is nothing I wanted to pursue, but GMC does not want to break the lease, I even said I wasn't interested in getting all my money back, just the deposit, and let me out of the lease. I have had the car 9 months and I only have 3100 miles on it because I never drive it. I have had it at the dealer 7 times in 9 month.

For all of you with shifting issues, the TSB #08-07-022 eliminated all hesitation and funny driving characteristics that may be bothering some of you. It didn't become available until the second week of May 2008, so some of you that just checked on updates, and were told you were current may not have had this one. It came with a warning about a possible decrease in mpg of 0-2 mpg. It holds the lower gears and won't shift into the higher gears as quickly. It also makes the downshift to 5th at higher gears less abrupt. I am completely satisfied and have seen NO mpg decrease. I get about 14 mpg with short in town trips and 21-22 at 76mph with an awd Enclave. I'd be interested to hear if those of you still experiencing problems have had this update.

I have had 3 updates, the last was on 5-21-08 and it drove ok for about a day, and went right back to slipping and being sluggish. It could me something else that the update did not cover. Never the less the dealer says nothing is wrong !!!!!!!!!!!!!!!!!

Did they give you a copy of the document which lists all of the shift points? My dealer gave it to me. Can you drive at 40-42 mph and stay in 3rd gear? If it shifts to 4th before 43mph, the newest flash did not take. I'd check the TSB# to see that it matches. The early shift before 43 mph would prove that the flash didn't take. It's possible that the tech isn't following the correct procedures. If it continues to not "take", then you deserve a different vehicle. Good luck.

Sorry, but in the above post I said it should stay in 3rd at 40-42 mph, but I should have said 4th. It should not shift into 5th until 43 mph. If it does, then your flash for TSB 08-07-30-022 did not get downloaded. I could cruise between 31-42 mph all day long and it will stay in 4th gear. It won't shift to 5th until it hits the magic 43 mph-not even using the manual shifting in "L". Go ahead and print my message and take it to the service manager so he can hear from someone with the update and how it should operate. It should not shift into 6th until 56 mph.

did you ever get the radio issue solved?
I just got my Acadia in March 2008 and I've been having problems with the radio. It pops, cackles and then the volume goes way down. The sunroof "grinds" when it closes and I lost all my phone minutes. Onstar said I used them, but I didn't. They then said maybe it is a hardware issue and gave me back all of my minutes and then some. The favorites for the radio also went from 6 "sets" to 3.
I took it into the dealership and explained about the problems. When I picked it up, they explained that they downloaded/updated some newer software for both the radio and OnStar and that they moved the deflector for the sunroof..."all fixed" they said. Nope!
Four days later, I smell electrical wires burning while I'm backing out of my drive way. Can't figure out what was "wrong" but the radio still pops, sunroof still grinds, and for a short time, it seemed like the rear assist thingy wasn't beeping.
Took it back in the next business day, and of course they can't find anything wrong with it. The service guy even tells me that "theorically they shouldn't be doing anything since they can't find anything wrong with it, but we will replace your radio." How nice of them! Ha, I dont think the radio is the problem and I didn't care for the "theorically" like I'm making this up!
My husband was just out with it and said that he braked, hit a bump, and the radio did its popping thing again! So ticked, anyone else have these issues?
