2011 Buick Enclave Owner Comments

On multiple occurrences, the fuel gauge does not accurately reflect the amount of fuel in the tank. It shows far less. Sometimes by turning on and off the car, it will reset. Other times it will take a day to reflect the right amount. Since there is a recall for this in vehicles manufactured from 2013-2014, it seems likely that this, too, is a defect.

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.

Inaccurate fuel gauge reading of my 2011 Buick Enclave. Has been happening for the last month and a half. I fill my tank up and it still reads that the tank hasn't been filled, also indicates that I only have say 60 miles when after a fill up it should read a range of at least 300 miles.

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.

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.
