A couple of things before I get back to the title. I have a end of the year 2007. A couple of months ago I received a letter from GM saying they had a computer upgrade that would enhance the performance of the transmission on the FWD SLT2 Acadia. I went in and had it done and immediately went on a two hour trip on business. The upgrade helped the shifting and I noticed and improvement right away. However, the upgrade wacked out the in Dash computer screen and the Mileage and Trip meter was wrong. I was registering less miles that I was actually traveling which wacked out the instant MPG readout and odometer. I took it back to the dealer that same day and when they called GM, GM said they were flooded with calls about the same thing. The dealer told me that GM would have a fix ASAP. I went in the Dealer the next day and GM had a software fix that put everything back to normal except that the odometer is still about 300 miles less than it should be. The dealer said that there is another computer on board that keeps the true mileage and that GM is working on a fix that would have the Dash board computer get the real mileage from the other computer. Until that time, I am still about 300 miles under what my true mileage should be. Back to the vibration. Soon after I notice an annoying vibration on the gas peddle that really becomes noticeable when I go past 1500 RPM and over ~42 mph. what concerns me is that the gas peddle is not connected to any linkage to the engine so there must be some serious vibration coming from underneath. I took is to the dealer 2 week ago and they said it was "normal" . I drove it another 2 weeks and decide to call GM and unloaded on them. They called my dealer and I am set up to go back in January 2 and leave it. GM nor the dealer claim to have a fix but I just wanted to alert everyone that the VIBRATION IS NOT NORMAL BECAUSE YOUR ACCELERATOR PEDDLE IS NOT CONNECTED TO THE ENGINE. If anyone has figured out what is causing this, let me know. If my dealer figures this out I will post it.

| I bought a 2007 Acadia in July 2007. Since my purchase it has been in the shop for a water leak from the sunroof. The first time it was determined that the drain tube from the sunroof to the outside of the vehicle had never been hooked up. A month later when my car passenger side floorboard flooded for the 2nd time, I was informed that there had been a memo put out on how to attach the drain tube, which my dealership had done incorrectly. Instead of them notifing me of the memo they waited until my car flooded the second time. I am very dismayed that I had not been notified of the possibility of a second episode of flooding. They say it is fixed now, but I am upset that they didn't replace my carpet, my glove compartment molded and now my car smells like mold and mildew. This is the only new car I will probably own and I believe it should be "NEW" for longer than 6 months. Has anyone else had this problem? Do you have any suggestions on how I can get my dealership to address my issues? | |

I did what you did.. took it back to the dealership.. at first, the mechanic said he could feel the vibration in the pedal, but he drove another Acadia on the lot and said it did the same thing.. he said there is no adjustment he could make, it is "normal" and just a characteristic of the car.. But, the gas pedal is not connected to the engine, so why is it vibrating ? I had test-driven a few other Acadias before buying and I hadn't noticed this vibration... it was only after I purchased the vehicle (that they got from another dealership) that I noticed it... I agree, I don't think it is "normal". The gas pedal is obviously loose and possibly rattling around ... When they were fixing the electrical problem, they gave me a Tahoe to drive as a rental... its gas pedal was tight, with very little vibration... I plan to drive some of their other Acadias when I am next in the dealership to see if they are all this way... we shouldn't have to put up with this inconsistent manufacture... |

Yes me again, After testing the car with a recording device in it for a month and nothing happens they took it out of my car last week and of course today it did it again to my husband. He was pulling out of the video store onto the highway luckily we know not to put our trust in this car considering the many times it shut off turning right and guess what it did it again this is 7th time I believe since July when we got this replacement vehicle. You call on star and it says nothings wrong. Why is it shutting off I just want this to be figured out. Please anyone else with this problem please email me.

Replying to: dawnk (Dec 28, 2007 7:40 pm) When the mechanic was test-driving my car to check out the vibration problem, he noticed that my key in the ignition had a heavy keychain full of other keys hanging on it... he said "you really shouldn't let the ignition key have this weight dangling off of it.. if the ignition key is pulled (such as when you are making a turn), the key can lose contact inside the ignition slightly and then the car thinks the key is not in the ignition and so the power goes out... you should drive your car with ONLY the car keys in the ignition and take your other keys off of the keychain while driving..." Others have stated that this sounds correct. Now, I drove my Blazer with a heavy key chain for 15 years and never had this problem... however, cars are almost totally electronic now and so possibly this can be a source of electrical and power problems. So, are you driving your Acadia with the car key on a heavy key chain ?? Maybe your "shutting off" problem is as simple as that... try driving it with only the car keys in the ignition and let us know what happens... thanx.. (Anybody else have any info on this ignition-key idea ?)
