Replying to: elias (Feb 02, 2008 6:35 am) Elias, Right 3000-4000 rpms. No hot roding here. In fact, I was on a freewar on-ramp this morning, the road was a bit slick and I was doing about 45-50mph and then I punched it and the wheels spun big time. Still normal? I guess I never have had a car do that. Thanks for the response. Replies to this message: 2saab (Feb 04, 2008 9:38 am) elias (Feb 04, 2008 1:31 pm) sidewinder101 (Feb 04, 2008 9:53 pm)

Normally at 45 MPH you would be in 5th or 6th gear and the RPM is probably around 1300. This transmission downshifts rather abruptly so you are quickly putting a lot of power to the wheels. With anything other than dry pavement I would not be surprised that you get significant wheel spin. Take it easy - your car will live longer, and so will you.
#167 of 492 Acadia doesn't start... by sybillcar Feb 04, 2008 (11:30 am)
First off let me say this in NOT a cold start problem. We have had our Acadia almost a year now and 2 weeks after purchase it started this problem. We could go out in the morning or after driving 400 miles, try to start it and it is dead, clicking sound or nothing at all, it has done it all. It has also died to the point that the remote entry wouldn't work, radio clock reset the whole nine yards. each time I need a jump after the jump it runs fine, no excessive driving required or battery charge needed. Could shut the car right off after the jump and it then it restarts just fine. I have had it in to the dealership and called onstar each time, and there is no recorded problem all sys. check come back normal. I even had the GM rep look at it...no help there. Battery has been replaced and it STILL does it. There is no memory codes in the computer...and no one is able to duplicate the problem so each time I bring it in to the dealer it is "fine". now I have it back and I am forced to drive it till dies again and then have it towed into the dealership. Hopefully it is convienant to me and my busy schedule and with small children I am nervous. I am currently in touch with BBB and the lemon law since i have had it in about 4 times for this same problem and no one seems to know what is wrong. I have never had the right turn stalling problem but I do get error messages about the traction control and stabilitrak needing service but then the computer never records these error messages either and the dealer can't fix what they don't know is wrong. also the nav. screen will go blank and the radio will shut off every once in a while when I start it and I need to shut off the car and restart it then it will turn back on...weird. My only answer to all this is that my acadia has multiple personality disorder...does anyone else have a "sybill" car???

Replying to: kchef76 (Feb 04, 2008 8:57 am) you are most welcome, kchef ! ya, on wet ramp, it's more likely/normal to see traction-loss like that...

Replying to: sybillcar (Feb 04, 2008 11:30 am) 8 weeks ago I had a no start problem (remote and ignition not functioning) that the dealer attributed to a faulty fuel sensor that misread when temperature dropped below -30C. They replaced the fuel sensor with a "new" version in December and it seemed to be working well until the end of January. In spite of block heater plugged in all night, ignition problem returned...just wouldn't start. Mind you it was  -51C windchill. Tow truck finally arrived 2 days later (I had tried starting once daily with no success, even though lights were bright, etc.) and I decided to try a start as it arrived (weather had warmed up to -20C). It started! I now believe the "battery saver" activates at some low temp level and prevents starting to save the battery. Since the battery is located under the floor in the back seat area, an electric battery blanket can't be used to keep the battery warm. I may have to try an interior car warmer solution, or build a garage! In addition, after the no start up problem, my Feb On Star report indicated my "oil life reading" had mysteriously improved from 40% oil life left to 100% left. I have decided to get an oil change this week and have it reset so I can trust it.

Replying to: kchef76 (Feb 04, 2008 8:57 am) My FWD Acadia w/ the 18 inchers has had no traction problems, no matter what the situation. Might want to try punching/merging it in the same or a similar location under safer conditions (i.e. not so slick). If you still experience traction loss in the manner described, it might be time to get the traction control system checked.

Replying to: rocket_08 (Dec 20, 2007 8:32 pm) This sounds like a ground problem. If the dash is not grunded good, many weird things can happen. Years and years ago had a grounding problem that when I put the turn signals on, the dash lights would flash. Plus many other weird electrical things. The mechanic added an extra grund for the dash and never seen the problem again.

Replying to: sybillcar (Feb 04, 2008 11:30 am) Sounds like you might need alternator. I would go back the dealer and force them with law suit to replace the alternator. Replies to this message: skupie (Jan 14, 2009 11:52 am)
#173 of 492 Re: outside temperature monitor [hsche] by lay1 Feb 15, 2008 (3:18 pm)
Replying to: hsche (Aug 17, 2007 7:18 am) The gauge on our 2008 Acadia has stuck on 35 deg on three seperate occasions even though the outside temperature was in the mid 60's. Today when this occurred the driver display warned of icy conditions and it was 67 degrees outside. We had it in to the dealer 3 days ago and they supposedly re-calibrated the sensor but when pressed about it today on the phone the service advisor said that it registered normal when they went to address the problem and thought it was fixed. It does seem to correct itself but only after driving for longer than 15 minutes at a time. We also have had the stabilitrac warning addressed by others in this forum and called onstar in each case. The 3rd time onstar gave us information (they said they couldn't give us a code) to give the dealer so that they could call onstar and ask for specific information related to the problem. The dealer called and all they could do was start a case number and told us to bring it in immediately if it happens again. Otherwise, my wife I I are very satisfied with the performance of the Acadia although I'll have to agree that the gas mileage claim is exagerated.

Replying to: lay1 (Feb 15, 2008 3:18 pm) Yes, my 2008 Acadia does the same thing: it can be 55 degrees when I leave work in the evening, and the temperature gauge continues to read 75.     After I drive for 5-10 minutes, the temp starts to creep down but one can never be sure what the actual temperature outside is....   Or it will read 85 when it is really cold ! I know that it is in the 40's and the car mocks me by reading 85 on the dash... I wish it worked better... it's a nice feature to have in an automobile..
