Scary problem in 2008 Acadia by rocket_08

Well, I took the car back to the dealership... they said the reason
the car lost all power was because " the positive cable was not connected well
to the fuse block" (it was loose).
They were able to duplicate the problem (i.e. suddenly losing power and the dashboard going dark).
 
They tightened the cable and checked all other electrical connections; they
said they think it's fixed and that I should not have that problem again...
 
Are they right ? Who knows ? I hope so... Someone else on this forum said that their Acadia shuts down unexpectedly like mine did and they could have been
hit from behind.... I worry about that, too... it is not a safe situation...
...But have your mechanics check the cables to the fuse block...
(at first, my mechanic didn't think it was that, because the clock stayed on and
was correct... but later he figured it out...)
 
I still have that annoying problem of the gas pedal vibrating under my foot
almost constantly... (does anybody else on this forum experience this ?)
The dealership said this can't be fixed or adjusted, it is just
a characteristic of the car... however, I don't believe this as another Acadia that
I test-drove did not have this problem... its gas pedal was tighter and more
confortable and it did not vibrate all the time...
 
Thanks for your replies... they were helpful....

2007 Acadia back hatch by angiemc
Dec 27, 2007 (11:55 am)

When I opened the back hatch in my 2007 Acadia to put some Christmas presents in, it extended all the way up, I leaned in with bags in hand and right as I was under it, it fell about 1 1/2 - 2 feet down banging me on the head. Then it must have reset itself because it started to close on me!
Hoping the wind had caught it, it was very windy that day, I tried it again with the remote (this time standing a safe distance away) and it did it again and has done so ever since. I plan on taking it in after the beginning of the year to have it repaired.
Has anyone else ever had this problem?

Did you get the update? How is your gas mileage now? My hwy has decreased to about 17mpg. Just wondering what you are getting. I have a 2007 Acadia FWD SLT2. I am not getting 22/mpg as before the update. I haven't called the dealer back yet and have put a 1000 miles on since the update.

My 2007 Acadia's back hatch just started making a loud "clunking" sound & jerking into place when it gets completely opened. It appears to be the gears on the support post (driver's side). The mechanic had lubed it & it was okay for a couple of days, but then it has started making that noise again. Will be calling the dealership again today!!

Vibration on Gas Peddle by safety9285
Dec 28, 2007 (7:08 am)

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.

Acadia sunroof leak by ddoan
Dec 28, 2007 (7:33 am)
Reply
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?
