The throttle body has a defect which shuts off all power to vehicle with no notice. The engine and transmission lock up you lose all steering control and no brakes. Also no lights so when it happens at night it is pitch black. GM does know about the problem and when I questioned them about the loss of life like what happend with the Chevy Cruze all members of GM are told to hang up the phone. It has happend on several occasions and the dealership sent me back on the road knowing the problem. Dealer rep said if I was a better customer thay may have done more for me.

The vehicle seems to want to cut off while at a traffic light! I simply do not understand why the engine seems to be so loud. I had both shocks and struts replaced after purchasing this vehicle. The entire frame seems to nose dive or "wander" while I am driving on the highway, totally uncomfortable feeling. Tires are basically new I just don't know what seems to be going on with this car!

Vehicle had recall 12212"a" performed in Oct of 2014 at delarship, this results in sometimes if not every time of a mis-calibrated brake position sensor. The mis-calibration results in my vehicle requiring the brake pedal to be depressed almost to the floor before the park position disengagement sensor is activated. It is at this point when the brake lights are activated. This extra pedal travel results in me being able to come to a rapid stop from 85 miles an hour on the freeway without any rear brake lights activating. The brake lights are not intermittent, they activate every time the pedal is pressed far enough, while driving this is only at the point when ABS would be activated under emergency braking. Buick/GMC is aware this is the case and issued recall 12212"B" on Oct 11, 2016 which reads: "this bulliten has been revised to include a note before step 4 of the service procedure. Please discard all copies of bulliten 12212A." The note states: "the brake pedal position sensor calibration must be performed after the brake pedal position sensor, BCM, ECM, or hpcm have been serviced." Buick/GMC has not informed drivers under the original 12212A recall that their brake lights will not activate because of this recall service and have refused to honor this newly updated procedure on my vehicle and shows as "complete" on nthtsa website. Bottom line the original botched 12212A results in brake lights not activating and anyone that had 12212A done should get 12212B notification and recall coverage.

Replaced engine a 2.4L laf and transmission a 6T-50 with bad trans @ 149K miles on 2011 Buick Regal. Replacement is 2011 2.4L laf engine and 6T-50 trans w/ 17K miles. Car now has P0089 and P228D codes and whine from high pressure fuel pump as described in #pip5203A. Turns out original engine is a 2010 engine with all the cam chain issues seen in other NHTSA complaints. To add insult to injury my dealer tells me ECM can not be reprogrammed to 2011 because programming is driven by the VIN# only. My only choice is to buy the parts from GM (about $1000) to turn my engine back into a 2010 engine or pay a dealer several thousand dollars to do the work. I`M in a position of paying several thousand dollars more for the car then it is worth. This was to be my retirement gift to myself, guess I will be driving my 1997 Pontiac Grand Am until I drop dead. Thanks GM, my brand loyalty sure pays off. My advice to future car buyers, buy another brand!! P.S. I hope this constitutes some emission violation and the epa hits GM with a multi million dollar fine. P.S.S. it dies on the road to. Where is marry B. when you her?

When driving or coming to a stop or even making a turning the vehicles shakes and then shuts off, this first happen when I was driving the car on a very busy street, the first time this occurred it happened with no warning just a shake and then the car shut off, reducing speed rapidly, causing the traffic behind me to do the same, thank god that there wasn't an accident, but it sure could have been.

In August 2016, I received an "important safety recall" #30710 from Buick. The explanation was "the wiring harness for the power seats may contact the seat frame, chafe, a short circuit could occur, resulting in inoperative power seat adjustments, flickering lights on the instrument panel, sparking or smoke under the seat, and possible fire." Having not heard anything, I contacted my Agency on 9/22/16 and was told "no parts were available." On 11/23/16, burns Buick said, "GM has no solution. I contacted GM and spoke with [xxx] who did not have an answer. On 11/30/16, GM's [xxx] suggested that no date or supplies have been set. Do I need to have a fire in my car while my grandchildren are in the back seat for GM to finally determine this is really an "important safety recall"" why should it take 5 months without any solution" I ride in fear everyday knowing that I am sitting on a time bomb. Please condemn this failure to provide solutions to this problem and fine them so that they do not do it to anyone else in the future.
