| Once or twice a week my enclave continues to roll another 5-7 feet after being put in park and the key removed. the accident occurred when i was unloading groceries from the rear passenger door. the vehicle moved forward and ran over my foot. i have a 100,000 zero deductible warranty, as well as gm's powertrain warranty, but still zubor buick in taylor mi wanted to charge because they couldn't find a problem. since my injury, i took it to another dealer today, red holman in westland. they couldn't find a problem either. it looks exactly like the recall with the 2009 enclave nhtsa campaign #09v073000 (on some of these vehicles, the transmission shift cable adjustment clip may not be fully engaged. if the clip is not fully engaged, the shift lever and the actual position of the transmission gear may not match. with this condition, the drive could move the shifter to park and remove the ignition key, but the transmission gear may not be in park.) | |||

| 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 fulls of water on occupants last year fixed. more definite hesitation between gears continues, as well as momentary lapses in power realtionship 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. | |||

| 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. *tr | |||

| 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. *tr | |||
