GMC Acadia Problems and Repairs
I bought my Acadia about 5 weeks ago and have a little over 2000 miles so far. I got a call last night from GMC Engineering asking about issues that I have had so far, whether they were annoying or otherwise. I've been reading the posts here and there seems to be some common issues, maybe we can all just list our gripes here and see if there are any widespread problems. The point is not to trash the vehicle, just see if our problems are isolated or common to all.
First, I am very happy overall with my Acadia. As an engineer, I had some concerns about buying a "new" model but I was in the market now, so I bought it. It still seems to meet my needs better than anything else out there. It's an SLE-1 with convenience, prefered & towing packages. It seems to be a fairly early production model because the window sticker is blank and there is a note about the pricing not being finalized. I believe it was delivered to the dealer in January, based on the state inspection sticker.
On delivery, I had the following problems-
1. Gas cap retainer was broken.
2. Headlight switch was loose (fell into dashboard).
3. There were still four outstanding "recalls"/TSB's- airbags, transmission programming, steering shaft lube, power seat wiring and rear door switch.
4. Problem with the keys and anti-theft system preventing it from starting.
All of these were fixed rather easily, though it took a few days because the dealership didn't have the programming for the recalls.
Since then I have noticed a few other minor things-
1. Transmission still shifts funny after reprogramming. The engine seems to lug a bit, it likes to run at 1200 rpm and is hesitant to downshift.
2. MPG overall is about 18. Seems a little low since at least half my driving is on the highway (low of 15.5, high of 23 mpg). I don't drive it particularly hard, so I was hoping to do a little better.
3. As others have pointed out- radio volume on FM is lower than on XM.
4. Noticed some condensation in the taillight lens the other morning. (fairly heavy fog that day).
5. There is a slight clunk from the front end when rolling from a stop.
I'll bring it in for the 5th one fairly soon.
How are yours doing?

You probably read this but here is a paragraph from Edmunds road test regarding downshift impressions:
"In our road tests we found the Acadia to be quite an eye-opening drive. Handling is respectable, especially considering the vehicle's large size and hefty weight. The Acadia's V6 won't blow you away with its power, but peak torque comes on early and the vehicle moves with decent authority. We noted that the Acadia's transmission can occasionally be hesitant to downshift, blunting passing performance somewhat. But overall, our editors feel that the GMC Acadia represents a compelling combination of functionality, luxury and value."

Ours seemed tight and trouble-free, with the exception of a tendency to drift right at speed - needed some alignment help. Great ride and wonderful silence...but also the biggest car [especially in width] that I've ever worked with - our Mercedes S-class cars from the past seem positively svelte by comparison.

Please report on your Acadia mileage over there. Thanks!
I currently have a BMW 740i (2000) and I get better combined #'s that what is being posted here and that is a bummer. I am getting 16.5 overall (city/hwy).
The AWD version will likely get at least 1 MPG less. Consider if you really need it.
Let me see if I understand what you are saying. You are surprised that a 5000 lb SUV with a large frontal cross-section gets worse mileage than your 4300 lb sedan that has a much smaller frontal cross-section?
That's just basic physics at work.
Well, I bought my acadia in April of 07 and did not have any major issues until this week. On Monday, I hit a dog ( I did not kill it) and about 1 hr. after doing so, my car would not start. An error messages saying: Engine power reduced, service stabilitrak, and something with the traction control. I got it started but it wouldn't allow me go over 15 mph. I finally got it to the dealership which took me 1 hr to go 20 miles. It is now Thursday, and they said they ordered a throttle and gasket. I read on the other forums that this is a BIG issue with the Yukons. I'll post when I get it back to let you know if it's fixed or not!
The first time, they changed a hose, and we had it back the next day. The CHECK ENGINE LIGHT was back on in less than 48 hours.
The second time, they kept it a week, and said it was the ECU that controls monitoring systems. This 'cure' lasted about a week.
Then the CHECK ENGINE LIGHT returned with an additional very bad symptom - the car wouldn't move, but the engine would rev while in Drive. My wife was on a busy street but turned the vehicle off, and then restarted it. It then would engage in gear again. The Check Engine Light was still on, so she drove it straight to the dealer AGAIN. The dealer now says the tranny is shot (2-3-4 gears specifically) after 1100 miles on flat ground with no towing.
We're both very angry, unhappy, and disappointed. This may end up being a lemon law claim before it's over. It'll be in the shop at least a week while they await parts (or a whole new tranny) from GMC.
:mad: &
Here's the link.
Has anyone had this problem because the service department is telling me that there will be a recall soon to fix this issue.
The other day it accelerated by itself on two different occasions while going down the highway at about 70 MPH. Just a short burst of speed and then back to normal. I also have had a little water come in after going through carwash, around my seatbelt where it is attached to column inside of car and down in foot well where you rest your left foot. Anyone else experiencing any of this? My dealer has no idea what is going on with battery or possible electrical system. He seems to think that the acceleration problem might be related to that also. I forgot to mention the leaks, so I will have to call them tomorrow. I love the car, but sure is a pain working out the kinks.
BTW: My Outlook (had it since Memoririal Day weekend) has run fine. It was great on a 1200 mile roadtrip over the 4th of July Week. No engine problems. Everything works fine.
After driving a couple of hundred yards the first thing in the morning I do hear a mild clunk that sounds like it comes from the front brakes, suspension or drive line. It’s the only time it does it so I’ll assume it isn't a problem. For the person who experienced an acceleration when cruising at highway speeds, note if you might have hit the speed control resume/increase speed button on the steering wheel. It is a bit close to where your hand/fingers might be. I have hit it a few times by accident without realizing it at first.
I will give another update in the future.
Any input on how to get this display back to where it was, i.e., showing both the artist and song title? FYI, I have the single CD and DVD 10-speaker Bose stereo without nav.
Thanks all!
I took the car in for service for these items. They told me that there was a bulletin for the water leak and it was actually the sun roof leaking. I was informed that the clunking in the front and rear was from the anti-lock brakes and that it's normal because the feature is actually turning on when I hear the sound. They told me that if I don't hear it, then it becomes a problem. They couldn't find a problem with the radio even though we have to put more bass in the radio now and turn the volume up higher.
The water leak in the sunroof was fixed, but the headliner had to be removed. Not sure how happy I am that the headliner has been removed and reinstalled, but what can you do.
