general problems of the 2011 Buick Enclave

We purchased a 2011 Buick Enclave for what we thought was a great deal. We were prepared to pay for basic maintenance right after purchase. The check engine light came on as we were driving on the highway. I noticed loss of power while on cruise control(set at 65mph) and the vehicle started shaking. I noticed the rpm jumping from 1 to 2 . We took the vehicle to Buick for repairs. We had a tune up, 2 catalytic converters replaced, 3 O2 sensors replaced along with one other one that I'm not sure the name, oil change, struts and shocks, rear sway bar links, air filter, and a gasket manifold. We have not had this vehicle longer than 2 months. The vehicle is still doing the same thing. Today after we picked it up from the shop(no check engine light) we drove it on the highway and now the service traction control light is on along with stabilitrak control. We have 6 children. This is dangerous. What are we to do?.

Timing belt issues at 140000 miles should covered since it's a known problem.

The fuel mileage reader is not working properly. . . Sometimes when I get gas it registers more mileage than it should. . . . Such as it may be on empty and the amount of fuel that I put in it should register that I would get 115 miles off it. . . . But it will register that I should get 150 miles. Sometimes it registers right and I can drive only 10 miles and the number of miles that I can travel will drop by 28 miles or more. It changes as I drive but doesn't show the proper mileage left as be appropriate. Also my heat is only coming out the vents in the rear and the top side dash vents and the bottom driver side floor vent. The front dash vents have no heat and the bottom floor passenger vent is blowing cool air. The heat problem is when driving and siting. The mileage reader is occurring when driving and after refilling and sometimes while sitting with the car running.

Fuel indicator is all over the place. Drop to zero and to half and full and back to zero.

While traveling with cruise control set to 79 mph, I accelerated to pass a semi that was driving erratically. After passing, I let off the gas but the gas pedal stuck. None of the cruise control buttons would work to slow us, the brakes would not slow us, eventually placing the car in neutral allowed us to safely stop along the road. Buick customer support basically said there's nothing wrong and until there's more incidents they won't do anything.

2011 Buick Enclave, all recalls completed. When turning into driveway from a total stop vehicle experienced unexpected acceleration and crashed through part-way up garage door, side wall of garage, (right wheel over 6" concrete foundation), pushed items stored in garage into front wall and moved wall 12" into laundry room. Vehicle stopped when left front wheel hit concrete step into service door although tire left tread mark on floor until engine turned off. Distance traveled was about 2 1/2 car lengths. Damage to right front mainly. $12,300 dealer estimated damage. Driver suffered soft tissue bruising, chipped tooth, soreness. Air bags did not deploy. Odb showed no dtc codes. Vehicle visually/manually inspected by dealer per insurance company request - nothing found. Claim filed with esis/gm central claims unit. Edr, sdm & cdr data were downloaded using bosch software and pictures taken of vehicle. Data/pictures were turned over to gm investigators. Owner contacted onstar for data but nothing was received by them. However, initial sdm data indicates 'onstar deployment status data sent' and 'sdm recorded vehicle velocity change data sent. ' investigation currently 3 months on-going, vehicle untouched. Vehicle also previously exhibited issue of free rolling backward or forward when stopped on an incline. Auto transmission and torque converter would not hold vehicle.

Similar to the recently announced recall on 2014 Buick Enclaves for a faulty gas guage, the same problem occurs on the 2011 model that I just purshased as well. I have owned the vehicle for 6 weeks and 3 times have experienced the gas guage indicate an inaccurate amount of fuel. Twice after the vehicle was turned off and turned back on, the guage reset to an accurate ready. However one after turning the vehicle off twice, the gas guage did not reset. . . . . It was not until the following day that the gas guage gave a accurate reading.

We were driving down the highway at 65 mph the stabilitrak / traction control light came on followed by an engine reduced power warning and the vehicle slows from 65 mph to 30 mph in about 3 seconds. The error message clears itself when the vehicle is turned off and left off for 1 to 5 minutes. The second time this happened we took it to the dealership and they reset the codes as a check engine light was also on. The check engine light came on again and the error message code indicated an idle problem. The dealer diagnosed and the TSB stated to relearn the idle which cost about $220. This problem occurred two more times with similar decelerations from 45+ to about 25 -30 mph in 3 seconds. The car forums on the internet for chevy traverse, GMC acadia list many people with similar issues. Many have called gm and have been told that gm is not aware of this as a major problem. Some claim there was a private recall on the 2010 models.
