I have a 07 Acadia and have the same exact problems. The dealer is trying to make me think it's normal and not to worry about it. Well I cannot ingore the problem cause it is irritating. I have had my vehicle in the shop 3 times all times the transmission was reprogramed and the 3rd time they replaced some parts that after it was all said it done did not work. I am so frustrated at this point because a person should not have to go through this with a new vehicle. Bottom line GM is no help they are just blowing smoke up my a--- I am in search for legal help at this point and will probably file a bbb complaint.

You might want to see if the antennae is still there. My wife and her sister both got new 08 acadias. The first time they took there car to a car wash the antennae broke off. First my sister in laws car, then my wife's car, at different times and at different car washes. I informed gmc. The dealer I went to said that it is not a warranty issue. He said that the car wash should replace it????? The dealer did replace both of them for us though.

I had the same experience and then some! The clunk was 95% resolved by a "update" at the dealer. As you know, it's the ABS system check, but sometimes mine would still occur while driving. That problem was addressed pretty simply.
My biggest complaint is how it accelerates! It's the worst, I test drove a couple of Acadia's and didn't notice this issue, ordered a car, signed the lease, and got this car that "clunked", and could not find a steady speed (or gear) due it's constant shifting and down shifting. At 20-25 MPH it's seems to be in third gear already, never really taching the engine enough, so it results in a very sluggish, unsteady speed. It is a constant struggle to get the car to safe steady speed.

I feel your pain. It's unfortunate that were are going through the exact same issue, but it makes me feel like I'm not crazy after listening to your same complaints!
I have an '08 Acadia. Test drove a couple of them liked it, ordered and leased it, and now I live with a car that I hate to drive. I got it Oct. '07 and have put 3100 miles on it because I hate driving it. It does not respond accurately to your pedal demands. It does own thing which proves to be dangerous at times. Because of the "variable" transmission is attempting to be more fuel efficent and lower emmissions, which I'm all for, it constantly struggles with where it should be.
I agree, as you accelerate, your expecting the motor to tach, then shift. It shifts before you gain speed which has a sluggish response on the motor, then you accelerate futher to "make up" some speed, then the damn thing surges, while the tachometer is bouncing all over the map. I've taken it in to the dealer 4 times, and have had a open dialogue with GM about this and as they all report the car is "performing as designed". So, they are telling me they can't do anything for me.
I can't believe I'm paying good money for a car that respond properly.
I live in San Francisco, with the hills in this city, the car responds horribly. I shouldn't have to think about how or when to make this car respond safely.
Yesterday, I had a very strange thing happen which was very scarry. Driving on a freeway which has moderate hills, I took my foot off the pedal and the car actucally surged for a second all on its own. I could feel and hear the motor do this. I was on the phone first thing in the AM to the lease dealer who arranged for me to get the car, and I am now looking into legal action.
I'm a nurse and I have a strong ability to detect when something is wrong, and there is something definetly wrong with this car and it needs to go back. I'm glad others are so happy with their cars, doesn't mean we should be stuck with ones that don't function properly, more to the point, mine is unsafe.

I have a 08 Acadia that I purchased in Jan. with the same shifting problems. When accelerating the car does not respond appropriately. It hesitates and surges. The engine seems to be woking too hard. It can be dangerous at times. The dealer told me it was just the way the car runs. I've also have problems with engine smells. I'm thinking it's all connected? This car has been a headache (literally).

It's unfortunate that after having this problem with the 07 Acadia that they did not have the sense to change of fix the problem for the 08 model. The funniest thing about it, the dealer told me that my situation was rare and they had no other complaints, after speaking with GM they said the same thing. I guess they don't think I would have the sense to explore the internet and research to see if anyone else had the same problem. I have read over 100 compliants of transmission problems , what part of rare is that ??? ( LOL ) I am so stressed out trying to figure out how to deal with GM and pretend I like my Acadia.

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.

I bouhgt my '07 Acadia in June last year....What you said here was exactly what happened to my Acadia until I brouhgt it back to dealer for the first maintenance and at he same time I had them done the computer software updates....The updates did work, it made the transmission work like normal.

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.
