2012 Buick Lacrosse Problems

Shows service stability track

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.

2012 Buick LaCrosse V6 (Fairfax Plant). The vehicle suffered a sudden, complete loss of engine power and forward propulsion while traveling at highway speed, cutting off mid-drive with no warning. This occurred alongside a persistent StabiliTrak malfunction; the dash showed repeated "Service StabiliTrak" warnings before the failure, then turned bright orange with multiple warning lights and a message instructing me to activate my turn signal and pull over before RPMs dropped to zero. Because power cut out instantly, my [XXX] son (passenger) and I were trapped in the center lane of a dense, multi-lane highway. I was forced to dodge high-speed traffic and coast the dead vehicle across multiple active lanes to reach the shoulder, creating an imminent collision risk to us and other drivers. We were then stranded on the narrow shoulder awaiting a tow, with traffic passing within feet at highway speed. Both my son and I have CMT2A (Charcot-Marie-Tooth disease), a neuromuscular disability limiting mobility; we were incapable of quickly evacuating the vehicle or reaching safety up the embankment, leaving us trapped in a highly dangerous position. No official inspection or diagnosis has been performed yet. My dash displayed the same "Service StabiliTrak" warning referenced in NHTSA Campaign 11V404000, though my VIN was excluded from that recall, and my failure went beyond the handling/deceleration issue described in that recall to a complete loss of propulsion.

Subject: Complaint Regarding Improper Handling of Safety Recall Repair Hello, I would like to file an official complaint regarding a dealership that failed to properly follow required procedures for a federally mandated safety recall repair on my vehicle. Vehicle Information: • Year/Make/Model: 2012 Buick Lacrosse • VIN: [XXX] • Recall Number (if known): Dealership Information: • Dealership Name: Castle Buick • Location: 7400 Cermak Rd, North Riverside, IL 60546 • Date of Service Attempt: May 2026 Details of the Issue: The dealership did not follow the proper safety recall repair guidelines as required under federal regulations. Despite the recall requiring specific corrective actions to ensure the vehicle is safe to operate, the dealer either: • failed to perform the full recall procedure, • refused or delayed the repair without a valid reason, or • returned the vehicle without completing required steps to ensure safety (such as proper inspection, adjustment, or alignment). This violates my rights as a vehicle owner, as federal law requires manufacturers and authorized dealers to correct safety-related defects at no cost and in full compliance with recall instructions. I am requesting NHTSA’s assistance in ensuring that the recall is properly completed and that the dealership’s non-compliance is investigated. I am concerned for my safety and the safety of others on the road. Contact Information: • Name: [[XXX]] • Phone: [[XXX]] • Email: [[XXX]] Thank you for your attention to this matter.

While driving stability trac, check engine light flashed and rpm, and speed gauges start going haywire. The car loses power even while accelerating, the steering wheel locks and car stalls. Then after 15-30 minutes the car starts fine and drives. Has happened at least 8 times. Took it to Buick dealer who ran diagnostic but unable to recreate codes but acknowledged a problem. Supposedly fixed it only to return the car a few days later. This is quite scary and dangerous as it happens without warning and while driving. Thankfully I wasn't on the expressway when it happened because all steering, power and brake function is lost.

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

I am the Fire Marshal in Ashtabula Ohio. Fire occurred in the driver's seat cushion. The origin of the fire was determined to be below the seat covering in the area of the springs and foam padding. the only competent ignition sources in the area are a computer module, power seat motors and seat heater coil. The computer module was eliminated during the investigation leaving only the heater and position motors as competent ignition sources. A review of repair records indicates the owner report power seat issues to the dealer in June 2021 that went unresolved. The dealer records indicate they were unable to replicate the failure. The fire self-extinguished upon consumption of all available oxygen; however, the smoke damage has resulted in complete destruction of interior. As a Certified Fire Investigator, I feel obligated to report a potential problem involving ignition of passenger vehicles.
