| 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. | |||

| 2011 buick enclave rolls uncontrollable on hills while in gear - drive or reverse. very hard to manage. 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. 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. | |||

| On incline when in drive -- rolls backward, indefinitely. on decline when in reverse -- rolls forward, indefinitely. this makes the vehicle extremely dangerous to parallel park on an incline/decline, as at some point you will need to take your foot off the brake to get going and when you do, the vehicle will roll forward (hopefully not hitting the car in front of you) and the accelerator will need to be applied enough to move the heavy vehicle against the grade (hopefully not so forcefully that you will risk hitting the car behind you). service department at local dealership pointed me to owner's manual (9-25): if the vehicle is stopped on a hill, with your foot off the brake pedal, the vehicle may roll. this is normal and is due to the torque converter designed to improve fuel economy and performance. use the brake to hold the vehicle on a hill. do not use the accelerator pedal. however, this owner's manual entry is in the drive section, and similar statements are not mentioned within the section about reverse. | |||

| Buick enclave 2011: the car rolls down uncontrollably on hills while in gear whether in drive or reverse, and is very hard to control. this also requires very quick movement from brake to accelerator. there is no hill hold feature and drivetrain provides no resistance. we deal with this problem every day while driving our driveway and into our garage. the minute we attempt to pull up to the garage, the car/suv starts rolling backwards and you have to conduct a couple of quick steps to stop it. i imagine this causes wear and tear on the brakes and other parts of the vehicle. a service rep at the dealership said this was normal and told me about other manufacturers that have the same problem from gmc. i drive a second car and it never does this. i believe this is a buick enclave problem. | |||

| The vehicle rolls back on any incline. there is no hand brake in the center console, and according to dot safety this is not legal. most crossovers and or suvs of this size roll back a few inches before the transmission pins engage and stop the roll back. i was told from gmc that the component was remove so that the transmission doesn't have to be serviced for 100000 miles. gmc told us the only thing they are willing to do is install and after-market hand control and will pay a percentage toward the cost. to me this sounds like a band-aid fix to a bigger problem. | |||
