Have had problem with my 2009 Buick Enclave rolling backward while in drive and rolling forward while in reverse if on ANY incline. Have taken it to local dealership several times and have been told it is a "characteristic" of the vehicle and there is nothing to be done to fix it. We were unwilling to accept this as the vehicle is unsafe in our opinion due to this defect, so we continued to work with the local dealership. The service manager has been doing his best to assist us, but the outcome has been the same...No solution for the problem. We were offered a new transmission by the GM regional customer care rep. and were thrilled, only to be informed by the service personnel that a new transmission will not fix the problem and would simply be a waste of time/expense. We were then asked to come in and look at other GM vehicles to see if there were any other vehicle that would meet our needs. We were immediately informed NOT to consider a new Enclave, Acadia or Traverse as all of these vehicles have the same "characteristic" as mine. In order to maintain the same amount of legroom in the 3rd row we were told the extended version of the Yukon was our only option. Not only is this vehicle MUCH larger than my Enclave, but the fuel economy is worse and the price was $20,000 more. I was informed the price difference would, of course, be our responsibility. While continuing the process with the dealership, several occurrences took place: 1.) almost backed into another vehicle while trying to pull forward in a line of vehicles; 2.) almost rolled forward into a parked vehicle in a driveway that was on an incline; 3.) almost hit 2 students who crossed behind my vehicle as I was attempting to pull forward 4.) hit a brick wall in my driveway while trying to pull forward This was the final straw for my husband. He took my Enclave to the local dealership, handed the keys to them and left it; telling them once again it was unsafe to drive and that we didn't want it back until it was fixed. We were contacted by GM and informed that an investigator would be dispatched to investigate the "alleged" incident. In the meantime, we were renting a vehicle. After approximately 30 days we received the answer from GM in Detroit, MI. They determined after driving my vehicle and others like it, this rolling issue is simply a "CHARACTERISTIC" of the vehicle and they therefore bear no responsibility for the problem. We were left with a now, damaged vehicle that still rolls backward/forward on any incline, an $1800.00 bill for the car rental while they investigated and the suggestion from the owner of the local dealership that we drive it with 2 feet, just like a manual transmission, but without the clutch! Our questions are these....If this is a "characteristic" of the vehicle, then why isn't it listed on any of the advertising materials or mentioned by the sales personnel so the consumer can make an informed decision prior to making the purchase? 2.) At what point does an undesired characteristic become grounds for a recall? Do there have to be a certain number of accidents or deaths before GM takes responsibility?
