SERVICE BRAKES, STEERING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Two warming lights come on when I turn the steering wheel - the ABS and the stability control light. When I turn the steering wheel both of these lights turn on. I viewed a video about this problem and the suggestion was made that the problem could be a safety issue and that it might be corrected by setting the car on a level spot and then turning the key to the on position (but not starting it) and then turn the steering wheel as far as it would go to the right and then to the left as far as it will go. Then turn the key to turn the car on. The problem I had trying that was that the steering wheel seemed to be locked in its neutral position so I was unable to perform that fix.

ELECTRICAL SYSTEM, STEERING
My vehicles started experiencing a Service Power Steering Code and Service Stabilitrak warning after I Replaced my Sway Bar Bushings and Sway Bar Links and Started Giving Me A Code On My Scan Tool Of CO55C:00, and Lost Of Communication With Electronic Brake Module(UO121:00) Code. I Also Have A Multi-Axis Acceleration Sensor Code. Power Steering Module, When I Disconnect my Battery Completely It May Delete Itself and my Steering Sometimes Returns, but If I Relearn/Recalibrate The Steering Angle Sensor and Clear The Codes With My Scan Tool My Steering Will Return. It Has No Specific Road Conditions, Speed, or Turns That Makes It Return, It Just Picks and Chooses When It Wants To Come On. I Checked All My Grounds, Wires, and Connectors For Corrosion or Other Damage. I Have Had An Alignment Twice and That Doesn’t Fix It Either. I Know This Same Issue Was A Recall On Other Models. Please Contact Me Back So My Issue Can Be Resolved. Thanks and Have A Blessed Day. I Have Been Trying Everything To Figure Out The Issue and My Car Has Been Sitting Since Mid December and She Only Has 94310 Miles On My Buick.

STEERING
While driving down the road goin around 45 mph all of a sudden my steering wheel got so stiff I could hardly steer the car off the road and out of traffic. I didn't hit anything, my power steering just stopped. I put the car into park and turned off the ignition after a few minutes I started it back up and my steering was back to normal. This has happened to me 2 times driving my 2016 Buick Lacrosse Sport. It's Dangerous and Honestly if your not paying attention it can cause a accident.

SUSPENSION
This vehicle has major suspension issues containing the complete strut assembly, lower control arms, and strut yokes/forks, which can not be replaced due to the discontinuance of the vehicle and parts itself. Because of this the car cannot receive an alignment which cause the tires to be eaten up at a rapid rate. When going over a bump in the highway the steering column goes one way while the car goes another. The car slides all over the road. Extreme safety concerns for my family and I.

SERVICE BRAKES
The break pedal sticks down during high temperatures ( generally during summer months especially when park outside in the sun and high humidity) and causes the brakes to drag and the break pedal doesn’t come up by itself! Also the brake lights stay on. It is very dangerous to drive on this condition. I just want theNHTSA to be aware of this and I have seen a lot of complaints on line I contacted gm and no response! It should be a recall for this! Please, help us with problem

ENGINE, ELECTRICAL SYSTEM
I am reporting a serious safety defect involving a 2011 Buick LaCrosse CXL. The vehicle has repeatedly shut off while being driven, creating a dangerous situation. The issue first occurred in January 2026. The vehicle was later towed for repair in February 2026, and I was told the issue had been fixed and picked up the vehicle 3/20/2026 and gave $1600. However, on April 9, 2026, the vehicle shut off again while driving. This issue has occurred multiple times and persists despite repair attempts. When the vehicle shuts off, it creates a loss of power and poses a significant safety risk in traffic. I am concerned that this may be a broader safety issue and am requesting that this defect be documented and investigated.

The contact owns a 2016 Buick Lacrosse. The contact stated that the fuel pump was previously replaced due to the vehicle stalling while driving. The contact stated that the tailgate unintendedly opened while the vehicle was parked and turned off. Additionally, the vehicle jerked while driving from a complete stop, and the vehicle hesitated and shuddered while driving at various speeds. An unknown warning light was illuminated.

FUEL/PROPULSION SYSTEM, POWER TRAIN, ELECTRICAL SYSTEM
When I get to a stop sign, and a stop light, when trying to accelerate after a complete stop, the car would struggle to accelerate to go forward. Where the shifting gears would start blinking, and the warning lights (engine power reduced, engine light, and the traction safety collision light) would display itself making it misfire and impossible to even go forward while pressing the gas pedal. It put me and other drivers at a safety risk because it would roll backwards after taking my foot off the breaks to accelerate where it would almost hit drivers behind me at the stops as well as them almost mistakingly hitting me in the back when my break lights stop reflecting when trying to accelerate at stop lights with traffic. I have had it diagnosed with the recall codes N20231344O GM # 20V668000 NHTSA # 18V576000 18V358000 But the dealships are saying there aren't any recall for the vehicle. This issues is ongoing.

POWER TRAIN
I had first seen a check engine light for a month and it would come on and off and sometimes it would stay off for about a week before it comes back on and do the same thing. I had noticed some slippage within the transmission a week prior to this incident and was looking to take it in for an inspection but money is tight so I couldn’t afford to go in for an inspection, especially a repair. I was driving to work and the vehicle was doing its slippage and I go about a mile or two until I reach an intersection, I came to a red light and stopped, when it turned green, I started pressing on the gas but the car didn’t move, it only revved. I then proceeded to put it in park and turn it off then on, only for it to do the same thing. So from there I had it pushed off into a nearby parking spot and then towed to a wrenchrite where they had confirmed it had nothing to do with the transmission fluid or anything minor. I then had it taken to Emory Services and they had confirmed the transmission its self had been fried.

STEERING, VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
during a regular drive the check stabiltrack system message popped up on the dash in the middle circle and then the little car with the squiggly lines behind it popped up and the check engine light came on and started blinking. Immediately I noticed lack of steering control, the car's speed was accelerating and decelerating on its own, jerking and stalling also was observed. As of now the car sits in my driveway because I don't trust the safety of it. I literally feared my life was in danger driving it because of the lack of handling and the acceleration shifts that were so random. So I returned home, as I pulled into the yard the vehicle jerked hard while I was attempting turn into the driveway causing me to hit my mailbox and damaged the side fender and front bumper. no one was injured but the car was damaged as stated before and I'm scared to drive it anywhere. The unpredictable behavior displayed in the vehicle puts other drivers at risk as well because I can't control the vehicle properly. so I'm guessing all in all its a malfunction somewhere in the electrical system. I have read about recalls in my type of vehicle involving the ESC and it appears to be what is happening with mine. As of now it sits in my driveway I need a remedy and fast because that was my only source of transportation and I'm a single mother of four with a lot to take of and no way to do it.
