2011 Buick Enclave rolls unabated on hills while in gear - drive or reverse. Very hard to control. Requires very quick move from brake to accelerator and "2-foot" driving which is dangerous and wears brakes and transmission. There is no "hill hold" feature and drivetrain provides no resistance.

My 2011 Buick Enclave rolls forward and backward on an incline when in drive. This is a serious safety concern as the rollback is not restricted and can reach dangerous speeds depending on the level of decline. This requires the driver to keep firm and consistent pressure on the brake when on an incline to avoid rolling into other vehicles and also, go heavy on gas to overpower the roll when taking off. This is even worse than a manual transmission vehicle as at least they will stop if they snub out.

This is an update to complaint 10280929 for a 2008 Buick Enclave awd after fuel efficiency reaching an all-time high of 17mpg combine hwy&city, within weeks it began dropping and settled between 14-15 mpg. Water leaks that began dumping cup full of water on occupants last year fixed. More definite hesitation between gears continues, as well as momentary lapses in power relationship between pedal and engine. Last month a whirring sound started that was associated with turning the car. The sound would rise during acceleration and fall during DE-acceleration. Break job took care of it (although I doubted the dealer's assessment) until yesterday. The whirring has returned, albeit intermittently. After 3 yrs I know that if a problem can't be replicated on test drive or show up as codes on a computer--the dealerships (and I have been to 3 over the years) will do nothing. My solution is to turn this pretty looking car in (3 weeks!) and turn my back on all gm cars after 30+ years of driving all sorts of them.

Within the last four months, I have noticed a vibrating noise as part of my steering. My major complaint is a very loud sharp whistling noise coming from my engine after driving it for a short time. The screeching, whistling continues while it is idling for long periods of time. I am concerned of what it is and also find it not acceptable to have to put up with the noise constantly, especially being only 2 yrs. 4 mo. Old and less that 25,000 miles. Obviously it is a defect by gm and they are responsible for fixing it ASAP as I'm not sure if the noise is all there is to it as far as safety. The technicians at the dealership worked on it, put in a new defibulator, took it back out and said they called GMC. According to the technician, gm said all Enclaves make the same noise. I am irate as not one on the lot makes the noise nor do any other's that I know people drive. I did not pay close to $40,000 for a luxury vehicle that sounds like a 15 year old clunker in which again is embarrassing as well needs to be reckoned with before my next description may be a big safety issue too! . . . . . . . . . . . . . . . . . . Take care of your consumers GMC as integrity should be #1 in your company.

I stopped on an uphill grade and the car rolled backward when I released the brake to move forward into traffic. I called the dealer and spoke with service and was informed that all 2010 Buick Enclaves did that. I braked the car again before I hit the car behind me. The car is now at the service department & they are checking it out.

On slight incline the vehicle doesn't hold it's position unless strong pressure is placed on the brake pedal. Otherwise the vehicle rolls back. Nearly rolled back into vehicle behind.

08 Buick Enclave normally downshifts and upshifts all the way up a hill. Took in three times and they said everything checks out normal, just drive it. Then driving out to arizona, it started out downshifting at the start of a hill and upshifting at the top of the hill like a normal car. Then once every five to ten hills it would not upshift at the top of the hill until I shut off the cruise control. Once I went five miles downhill before I shut off the cruise and it upshifted. I took it in to the dealer, but the few miles they drove it, they could not make it happen. They said there were no codes so there was nothing they could do, so just drive it like it is, as its still under warranty. It had also happened only once before when it was new,but they could not find anything either. I don't know if this is connected or not, but if I want to accelerate slowly,I have to push the gas pedal down farther and then back off quickly to not accelerate too fast. I sure hope they can come up with a fix for this problem.

2008 Buick Enclave that has had transmission problems for 8 months (new car was picked up in August of 2007). After several service attempts to fix this problem, it still doesn't perform like it should. Today when driving the car the engine was racing to over 4,000 rpm while driving down a 35 mph road -- thought the thing was going to blow up because it wouldn't shift into the next gear. Also had water (from rain) on the inside of the car after it rained due to faulty rail connectors (not sealed) on top of car.

From the day of purchase my Buick Enclave has failed to achieve the rated the fuel efficiency (12 mpg initially upto 14mpg 18mos and numerous trips back to dealerships. Basically computer checks and adjustments were done. Finally, last month a valve job was done, as well as some transmission work and now my fuel efficiency is improving. I have driven 400 miles since this mechanic work and the mpg is approaching 17mpg.
