The volt meter on the dashboard keeps dropping below 14 volts and 13.5 volts. The car has been checked by Buick and my mechanic no issues found. Buick has no idea why it keeps doing it neither does my mechanic. The problem is if there is a voltage drop, the computer will shut down the engine because of the low voltage. This could happen while driving which could be a serious problem. The date I provide is the last time it occurred, but it happens on a continuous basis.

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.
NHTSA complaint #11741241 — an unverified report by a vehicle owner.
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.

NHTSA complaint #11705471 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11698766 — an unverified report by a vehicle owner.
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.

Low beam headlights randomly turn off while driving at night and day. Causing not to be able to see the roadway at all. Very dangerous!!! They give no warning at all. Only the low beams do this. Bright lights are not affected. There was a recall for this issue but they said my car was not affected. But it is 100% affected by this recall. Ot seems like the Headlamp driver module is overheating. It gets extremely hot. This issue almost caused a very serious accident .
