The component is the brakes and the brake pedal while not engaging the brakes they remained on even after the vehicle was shut off.the vehicle brake lights remained on this was not duplicated when I took the car in by the dealer of how the brake remains engaged we even when not being used I would have to release the break by pulling it up with my foot while driving. This was duplicated and witnessed by two others the dealership where I bought the car and a trusted mechanic. which no avai there was no warning light indicating any type of concern prior to it doing this. the brake pedal being slightly stuck my transmission shifts not properly and hot feeling to the car now I have a warning saying that AC will not work due to the overheating of my engine which I believe to have repaired however the repair that was believed to be the problem obviously wasn't the problem because the light still remains on and the fan runs continuously the minute I start the car to the time I shut the car off I live in North Dakota and it is -1 today and the fan continues to run at all times and the warning light is on cooling fan the car lunges at times which is easy to lose control over when it does this it lunges to the point where it physically noticeable and and no warnings of this that a compensation is going to need to be made in my driving with this lunge issue. I do feel this break issue has affected many other parts of the vehicle and the safety associated with these components. Also at times the driver's seat will not move it goes up to the dash or back to the back seat leaving me in a position where I cannot drive the vehicle safely at all. Also the cruise control would not engage because of the brakes being slightly engaged. Took her to the dealership discussed this problem with them and they could not duplicate and it's been going on since I purchased the car It had 30,000 miles on it when I bought it and it continues to do this and I think it's a safety issue

Every time I will drive for so long I'd lose all power radio dash lights headlights everything and start blinking and going out and finally the car was just die. Come to find out it is electrical issues and it's costing me more than the car is worth to even get it back from the shop.

Driving 60 mph on the highway. Suddenly the information panel flashed stabilitrak service required (or similar) then low power mode. Car went from 60 to 30 mph on the highway. Unable to speed up. Needed to pull over to the side of the road. Turned car off. Tried to restart and it wouldn't restart for several tries. Restarted and still said low power and was idling low. Tried again and was normal. This has happened several more times and always is similar. Sometimes it doesn't happen at all in a 30 mile trip, sometimes it happens 3 times. Very dangerous! could be rear ended! I have read many other accounts of this happening in the 2011 Buick Lacrosse. After this the check engine light stayed on. When I had the auto parts store run diagnostics it flagged multiple misfires, throttle position sensor 3 times, power control module indicator, traction control. It seems this is a flaw in this car. I attempted to get a picture of the satbilitrak sensor indicator light, but it flashes on and off pretty quickly and you never know when it will happen.

While driving uphill in the winter, went to turn into neighborhood at top of hill, just as turning the vehicle, vehicle died. Everything stopped working. Engine shut off, brakes wouldn't work, steering wheel locked, lights went off, then wouldn't start. Then the vehicle instructed to roll driver window down then up, roll right window down then up. Almost like it was trying to reboot. But this happened in the middle of driving. After trying a third time to start, it started. All information was gone, no mileage, oil life gone, tripometer gone. Drove vehicle home, just a block away and been too scared to drive the vehicle since.

Potential fatal safety hazard with door lock pull toggles when an accident disables the battery. In normal operation, the electrical system always retracts the door pull toggles completely into the top of the door during any shift of the vehicle out of park. The pull toggle disappears completely into the door with no portion exposed. If the vehicle battery is disabled, as in minor crash, the electric windows cannot be operated and the door cannot be open manually. The occurpant is locked within the vehicle until a window is broken out. There is simply no way to override the electric system to exit the vechile. Pulling the door handle does not override the electric door locks. A simple fix would merely be to make the plastic pull toggles 3/4 in. Longer so that somone can grab the toggle and pull it to the unlocked position even though the vehicle had been electrically locked.

This vehicle stalls/cuts off while driving. It can occur while driving or taking off from a stand still. It maintains a stored history code P0014 and after service will reappear. Especially dangerous while driving in the national capital area. Buick has a notice about the engine control module and that has to be reprogramed for that vehicle model and my VIN number falls within that bulletin. The problem is that it doesn't work and the vehicle shuts off at a moments notice. Right now I'm afraid that my life or someone else is ir real danger. Unfortunately I'm not the only one. While searching for a solution I found numerous owners with the same problem/ same complaint. I hope it doesn't take the loss of life to address this issue.

- Stafford, VA, USA

Vehicle completely dead after all types of electrical messages displayed when trying to start. Car was stationary both times. This first happened early Feb 2016; then repeated similar scenario 20 days later. Car was towed both times. Low mileage 52,278 miles. Messages generic, dealer could not determine problem and contacted the GM customer center also. Nothing done first time. Second time dealer started updating all the electronic modules-although again no specific cause and effect could be identified. Modules updated (ebcm, BCM ECM, etc. About 27 modules. Thus far car has not been dead again with exception of battery issue (already another warranty replacement for original). My concern: If these electronic modules (couple thousand of dollars) are the problem, how come it was not a recall vs repair. Owner should not be a hostage to a software update for a repair to make the car start? of note; my car has had 21 warranty fixes with my low mileage. GM prior to this electronic failure extended my warranty out due to the many issues after I was forceful. Basically, GM engineers are producing a car where they cannot definitively state the problem, but start trying everything. These module updates would cost couple thousand dollars and lots of time in shop. Note: My auto is a 4 wd larger engine Buick; fob vs key so somewhat fewer on the road. My auto was one of the first 2011 that rolled off assembly line probably but very similar to the 2010 (first year out with the current body style). The other 21 warranty jobs (driver seat, passenger side traffic warning message, oil leaks, transmission leak at same time as engine oil leak, problems with doors opening, radio nav system, right rear hub bearing pad, and a couple driven by the actual repair visit.

Defroster, heat, A/C, fan speed, recirc, heat/cool seats functions failed (stopped working completly) while driving in a snow storm on January 12, 2016 on highway us 131 to traverse city, mi. Found recall information NHTSA # 11V149000. Brought to dealer. Dealer said not coverred under recal due to VIN #, and owner cost of $400 + to repair. Contacted Buick customer care. Spoke with asia and leslie on 1/15/16, who said GM could not help. I described language of the recall as being identical to the safety hazard described in the NHTSA language: "windshield defrosting and defogging systems" on these vehicles, the software in the electronic climate control module may disable the ability to adjust the heating, ventilation, and air conditioning system settings. If this happens, the driver will not be able to control the cooling and ventilation for the vehicle. Consequence: If this condition affects the defrost system when it is required, it may decrease the driver's visibility and could result in a crash."

Vehicle has been operating normally. It just came off warranty a few weeks back. Wife came home and parked the vehicle in the driveway. Went out several hours later to go somewhere and it would not start. There were no warnings of a problem. When we turned the ignition key we heard a few clicks and then nothing. Lights we noticeably dim. We were able to get it started with a jumper and let it run for a while. It will be serviced in the morning. It appears the problem is with the battery or there is an electrical problem in the system. While we were running, we checked to see if there were any codes and could not find any. The car was parked on about a 5% incline facing down. We used the incline to move the car to a flat area where we were able to jump start.

On more than 10-15 occasions I've experienced intermittent failure of the keyless ignition, whereby there is only one click and then no ability to start my vehicle unless I continue to press the button while turning off any and all ac, radio, power etc. I purchased the car used 1 year ago in excellent condition but noticed that it already had a new battery that was installed earlier in 2013.the vehicle is a 2011 and that seemed very odd. What I've noticed is that the battery terminals continually corrode mostly on the "positive" terminal and I've removed and brushed them several times and tighten, and that seems to work when it just absolutely won't start. Big inconvenience when I'm usually dressed in a suit... unfortunately, I've taken it to three different GM Buick dealerships over the past month and a half and it never will reproduce the defect when I'm there, so they've not been able to evaluate and remedy. Noticed service bulletin pi-0412 for parasitic drain/discharge so now I'll take it to another dealership to see if they can determine the cause based on this. Very frustrating to not be able to have this diagnosed and corrected before I potentially find myself totally stranded away from home.

2011 Buick Lacrosse. Consumer writes in regards to vehicle integrated flip key system. The consumer stated he noticed a problem while driving his mother's vehicle. In order to activate the ignition, the driver must extend the Buick integrated flip key. After the flip key was inserted into the ignition, the driver must turn the Buick integrated flip key device to start the vehicle. During the process, the driver often inadvertently placed pressure with his or her thumb or index finger on the trunk latch disengagement switch. The switch disengaged the trunk security latch. However, the trunk did not open, to the point where it was noticeable to the driver or passengers. However, while stopping, the un-latched trunk inevitably opened.
