Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

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.

Check engine light came on and vehicle suddenly reduced speed while driving on residential street. Message displayed on panel, "engine speed is reduced." In a separate issue, we were advised by the dealership to keep driving the vehicle even if the check engine light appears to empty out the fuel. The dealership believes the fuel is bad. This may be related to the first issue, but I am unsure.

I was driving on a 2 lane road in a 55mph zone, at 40mph accelerated to pass a vehicle and accelerator pedal took over and accelerated to 87 mph and would not release. Brake was stiff and would not slow vehicle or release accelerator. After 30 seconds of jiggling gas and brake pedals it came back under control and released. RPM gauge was going up and down at this time as well. This problem nearly caused a crash if another car was in the lane or oncoming traffic.

This particular problem is with the cruise control mechanism and it's ability to manage the command which is given. The 1st occurrence happened in 01/2014, on the 1st drive of the day. Temperature was 44, sunny and roads were dry. I locked in the cruise control at 55 mph and when I went to decrease the speed and lock it in at 45 mph, the cars speed increased 10 mph after one press of the cruise control button. The car quickly increased its speed until I realized what was happening and pressed the brake. The following week it happened 2 other times at different speeds (50 mph and 40 mph). In the first instance the cruise was set at 40 mph and I wanted to increase it to 55 mph. After only pressing the button twice, it jumped 15 mph displaying a cruise speed of 65 mph. In the 2nd instance, I was decreasing speed from 55 mph down to match traffic (no specific speed was intended) and it increased the speed 10 mph after the 4th or 5th press of the cruise control button. I have actually witnessed the speed change on the display and add 5, 10 our 15 mph quite a few times now. Each time the car will increase its speed after a few seconds delay. There has also been multiple incidents where I was trying to increase speed and it actually decreased speed. After multiple instances, I brought the car to the GM dealership in carson city, nv and expressed my concern. They said they could do nothing as they couldn't duplicate the problem. Though this happens quite frequently, it does not do it every time. It must be noted that it does not happen at a particular speed, and happens both on increasing as well as decreasing your speed. Thank you for your time and consideration on this matter.

On March 27 2014 my Buick Enclave gave me an error message on the dash while driving on the highway traction control off, stability transmission needs service, and reduced power came on.the car went from 60 mph to 50 mph suddenly but then cleared up.I took the car into the dealer to be serviced on 03/28/2014. The local dealer stated that they found the issue and corrected it.on April 16 2014 I had the same issue however the event was much worst. I was on the a major highway doing 65 mph. The car did not give me any indication of any isssue. The dashboard displayed traction control off, service traction, and service stabilitrak and very quick and suddenly I lost all power to the car while traveling down the highway at 65 mph. The speedometer stated I was still at 65 mph however the car was not traveling at 65. I tried pulling on my hazard lights but they did not work at the time. The power steeling on the vehicle did not work. The gas pedal did not excel the car. I was almost hit by a tractor trailor who was traveling behind me. I tried moving to the slow lane however the car had no power sterring but the engine was on and the gas pedal was to the floor but the car was not acceleration. I had no power in the car, I was able to get to a safe spot were I tried turning the car off and back on. That did not solve any issues except for the hazard lights. I was then able to put on my hazard lights. The car never gave me an error that I had reduced power. Everything occurred in about 2 minutes. I immediately contacted the dealer to have the car towed. I have major safety concerns about the 2011 Buick Enclaves!!!!! I am very lucky that I was not killed on hwy 540. I don't think my air bags would have deployed if I were hit by a tractor trailer or car. Nothing was working in the car. Please call me with any questions!!
