Whenever the vehicle is in drive and on an incline the vehicle will roll backwards excessively if the brakes are not held. If I pull up to a signal light or intersection where there is an incline my heart is beating so fast because I am afraid the vehicle is going to roll backwards onto the vehicle behind me. I have been told by a dealership repair representative to "just apply the brakes." Well, you have to release the brakes in order to accelerate and merge into traffic and when I release the brakes to proceed, the vehicle will roll backwards unless I hurry up and accelerate (doing this, I run the risk of crashing into oncoming traffic). If there is a vehicle directly behind my vehicle, I could possibly roll backwards into it or into someone walking behind my vehicle. The dealership repair shop continues to tell me this is "normal". none of the vehicles my family has ever owned or that I've ever driven has done this. The dealership repair manager test drove other Enclaves on the lot and he said they did not roll backwards in similar situations. But when he test drove another 2012 Buick Enclave it also rolled backwards when on an incline and in drive. He told me that since the other 2012 Buick Enclave also rolled backwards, that he considered this as "normal". I told him it's not normal for a vehicle to excessively roll backwards like that; in my opinion this is a serious 2012 Buick Enclave issue. What am I to do if the brakes, god forbid, should also go out. I'm afraid that if I'm going up a bridge or something I'm going to roll backwards to my death.

Multiple instances of the transmission slipping into a "neutral-type-state" while attempting to merge onto/into highway speeds. This has occurred over 20 times in the last 1.5 years. Dealership took car on multiple occasions and was able to replicate it 1X. Their corrective measure was to re-download transmission software. This did not fix the issue. This is an intermittent problem that poses a significant safety risk, as the slippage can last anywhere from 1 to 3 seconds.

Whine or whistle noise. Dealer stated it was low power steering fluid; rack and pinion leaking. System replaced but noise continued. Returned for more work in 5/5 and 5/27/2014. Dealer finally said nothing can be done about the noise, but everything is working according to specs. Noise continues. Buick customer complaint rep. Said nothing is wrong, that everything is according to specs, even though the noise was absent for the first 16000 miles. Customer complaint case number is [xxx] my concern is something is wrong and Buick isn't saying. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I stopped at a red light on a hill and when I took my foot off the brake the vehicle started to roll backwards.it would roll backward when it was in drive. I almost hit the car behind me. Then I went out of town and tested it on other hills and it did the same thing. When I was going downhilli stopped and I put it in reverse and it rolled forward. When I was going uphill in drive and stopped and took my foot off the brake it would roll backward until I put my foot on the brake and as soon as I came to a stop and took my foot off the brake in would roll backwards again. It would have rolled to the bottom of the hill. This could be very dangerous.
