#83 of 112 Buick Enclave engine rpm in mountains using cruise control
Dec 12, 2012 (11:27 am)
Buick 2010 Enclave. 29,000 miles. Situation: using cruise control in hilly country or mountains.
Problem: When cresting hill and then going downhill, engine stays at 3800-4000 rpm even though vehicle is rolling downhill and needs no power. When I hit brakes to take it off cruise control, nothing happens. Then, when I step on gas pedal and let up, rpm drops back to 1800 rpm (a reasonable rpm when no power is needed). Clearly at 4000 rpm engine is not engaged to transmission, as I do not gain speed. But rpm need to crest hill holds until I step on gas and let up. Any help or confirmation of similar situation would be appreciated.

Have you had this evaluated by your dealership? If so, what did they find?
We certainly understand if isn't something you've done already and are just trying to get a feel for where the situation is at.

Called GM service before my post. The service rep had not heard of this yet and was going to check with techs and call me back. Have not heard back but I am thinking of taking in for service -- but am concerned that if they have no track record -- what is my likely outcome?

Good morning pinnacle49,
Does this revving of the RPMs happen consistently? If not, there's always a risk of them not being able to duplicate your concern - I would certainly advise that you have a tech drive with you if you're not certain this will happen every time or that they will not notice it.
Given the model year of your Enclave and the mileage, you are likely still within your bumper to bumper warranty. However, if you have questions about warranty coverage that are unanswered, we can check into that. Send your request and the last 8 digits of your VIN to us via email at socialmediagm.com (we will be able to tie your email to any open Service Requests you had started when you called into the Customer Assistance Center).
Sarah, GM Customer Service

I have an appt for Monday. However, mountains are an hour away, so don't know how we will duplicate the hills, etc. Hopefully they can figure something out. Thanks for the response.

#89 of 112 2011 Enclave RPMs issue?
Jan 25, 2013 (11:26 am)
I know nothing about cars but am going to try to explain my issue. When accelerating on freeway (like trying to go from 55 to 60/65+, the RPM needle stays below 2 and the car seems to "hang up" until I floor the accelerator to get it up to the desired speed. I have taken it to the dealer 2x, they claim they can't duplicate it so I leave with it unresolved. If I have to accelerate in a hurry to adjust to traffic conditions, it seems like it just won't get moving quick enough, which is pretty nerve-wracking. Is this how it is supposed to be in this size car? Also, have been reading these blogs and on other sites and I too have that issue of the car rolling backward while on an incline unless the brake pedal is jammed to the floor. When it is time to move forward, it rolls back and you need to make an extremely quick switch between the brake and accelerator. Embarrassing when you end up burning rubber on a hill!
#90 of 112 Warranty Question
May 28, 2013 (7:46 pm)
I have a Buick Enclave that the transmission died. I have under 100k miles on it. The warranty was good through 100,497 miles and expired just a few months ago. Dealship is saying they called GM and since it is a few months expired it is not covered. Has anyone delt with a situation like this? Any advice would be great since this is a big ticket repair.

Finally took car back into mountains in Utah. Had vehicle in cruise control. After hill crest car began descent (in cruise control) and rpm stayed at 4000 all the way to the bottom. Had to hit brake to take vehicle off cruise control in order to get rpm back to 1900-2000 where it would normally run at my speed. Not sure what to do next since dealer had no answer.
#92 of 112 Transmission issue and trade in is worth scrap ?
May 31, 2013 (4:56 am)
I recently posted that our Buick Enclave 08 transmissiion died andPower Steering pump failed. Warranty is under the miles but over on time. Dealer called GM and the offer was to cover a small portion of the $5652 cost of repair.
Service said I may want to talk to sales to see what the trade in would be and weigh out options. I called and was told that my car would be either scrapped or wholesaled out. This blew me away since I have a friend that does transmission repairs in another city that works for dealerships rebuilding transmissions and then they resell them.
Any advice of what to do?
