POWER TRAIN, UNKNOWN OR OTHER
My 2017 Buick LaCrosse Premium AWD (116,220 miles) experienced a severe all-wheel-drive failure causing significant binding and a loud rumbling/clunking noise during sharp, low-speed cornering and acceleration. The vehicle has been officially inspected by two separate authorized manufacturer service centers. On September 25, 2026, a certified GM technician at Advantage Buick GMC formally documented that the vehicle has a prominent rear drivetrain failure, identifying it as a "rear diff or driveshaft issue" that requires full component replacement. Prior to the complete mechanical failure, no warning lights or dashboard indicators illuminated. The binding symptoms appeared suddenly during normal city driving maneuvers. This drivetrain failure directly aligns with documented corporate engineering safety campaigns, specifically Customer Satisfaction Program #16069 (propeller shaft/driveshaft C-clip disengagement defect) and TSB #18-NA-049 (catastrophic twin-clutch carrier assembly failure). The failure of this component poses a severe, immediate driving hazard as a sudden disengagement of the driveshaft or differential lockup at road speeds can result in a catastrophic loss of vehicle control. General Motors has ghosted my corporate case (#113840289) and refused to remedy this manufacturing vulnerability

VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
My 2017 Buick LaCrosse Premium AWD experienced a sudden, dangerous mechanical failure of the Accelerator Pedal Position Sensor system while operating the vehicle under normal road conditions. The vehicle suffered an immediate loss of engine continuity and engine power, forcing the car into a hazardous low-speed limp mode while in active traffic. A certified repair facility inspected the vehicle, confirmed a complete failure of the internal pedal sensor circuit, and replaced the unit to restore safe operating throttle control. This specific electronic and mechanical defect represents a widespread manufacturing vulnerability that General Motors has officially acknowledged under Special Coverage Adjustment N182188250. This failure poses an immediate safety hazard to occupants and surrounding traffic, as a sudden drop in throttle response on highways or busy intersections leaves the driver unable to maintain safe traveling speeds or accelerate out of oncoming hazards. General Motors has opened Corporate Case #113840289 regarding this failure but has failed to issue my safety reimbursement.

ELECTRICAL SYSTEM
**Subject:** Formal Safety Defect Complaint: Premature Failure of Completed Recall Remedy (NHTSA Campaign 13V173000 / GM Recall 13136) Resulting in Sudden Loss of Power Steering **VEHICLE INFORMATION** * **Year/Make/Model:** 2012 Buick LaCrosse Hybrid (eAssist) * **VIN:** [XXX] * **Current Mileage:** [Insert Current Mileage] **DESCRIPTION OF SAFETY DEFECT & INCIDENT** This vehicle was previously serviced under NHTSA Campaign 13V173000 to resolve an inherent defect in the Generator Control Module (GCM) that presents a severe stalling and trunk fire risk. On 9-9-26, under normal driving conditions in ambient temperatures of approximately 95°F and after covering a distance of 10 miles, the manufacturer-installed remedy component suffered a premature, catastrophic thermal failure. The replacement GCM ceased regulating and delivering power to the vehicle’s 12-volt system. The resulting critical voltage drop forced the vehicle into an emergency load-shedding protocol, abruptly disabling the air conditioning system. Shortly thereafter, the severe drop in operating voltage caused a total, sudden failure of the Electronic Power Steering (EPS) while the vehicle was actively in motion. The driver was forced to navigate a heavy vehicle entirely without steering assistance, causing an immediate, severe collision hazard. Battery warning symbol activated. I have not taken it to the dealership because of the recall status. **REASON FOR ADVANCED ESCALATION** While the vehicle’s VIN status officially shows "No Incomplete Recalls" because the campaign was previously executed, the remedy part provided by the manufacturer has failed in the exact same manner as the original defective component. By failing prematurely, the safety risk mandated to be fixed by federal law has been completely reintroduced. REQUESTED ACTIONS Manufacturer-Covered Remedy: A goodwill replacement of the failed Generator Control Module and associated diagnostics at no cost to the owner.

ELECTRICAL SYSTEM
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.

ENGINE, FUEL/PROPULSION SYSTEM, SERVICE BRAKES
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.

AIR BAGS, SEAT BELTS
On June 22,2026, I was involved in a frontal impact collision while traveling at approximately 35 mph. The vehicle suffered a catastrophic failure of the entire occupant restraint system. Despite a severe, high-speed frontal impact, the frontal airbags failed to physically deploy, and the seatbelt pretensioners failed to tighten, leaving the seatbelts completely loose. Crucially, the dashboard instrument cluster displayed a message indicating that an airbag deployment event had occurred. A check of the VIN shows no open recalls, meaning the GM SDM software update (NHTSA Campaign 16V651000) was likely marked as completed by a prior owner. However, the system completely failed to function as designed during a major crash, mimicking the exact symptoms of the original defect. The vehicle is currently held at a private tow yard pending an insurance investigation and an Event Data Recorder (EDR) download.
