2017 Buick Lacrosse Recalls, Ratings & Complaints

Incident: November 15, 2025 · Filed: September 29, 2026

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.

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

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.

The contact owns a 2017 Buick Lacrosse. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the front driver's side wheel well. The contact stated that increased effort was needed to maneuver the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the front driver's side strut. The vehicle was not repaired because parts were not available. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was unknown. The VIN was not available.

Incident: December 13, 2023 · Filed: July 20, 2024

The air bag warning light in the dash came on intermittently during driving. I took the vehicle to the dealer for service December 27, 2023, since it was a safety issue that the authorized dealer needs to take care of. At first, they said it was a bad battery and the safety system needed reprogramming. Which they did for about $800. When driving home from the dealer the air bag light came back on so a few days later I returned the car to the dealer. Then they said it was the passenger seat safety module that needed to be replaced. That was back in January of 2024, over 6 months ago. At that point I learned that the car is not drivable since the air bag could deploy at any time or would not function if requested in an accident. General Motors says they do not have the part that is critical to the operation of the air bag system to replace. That was over 6 months ago, with no prediction when they will have the part. This is a critical part of the safety system that they can't replace which leads me to believe there is more to this than they are telling me!! Federal law requires them to have parts for vehicles less than 7 years old - they don't!! How many other vehicles have this part? Is the part defective since it failed without any other causes that could be identified? Why can't they replace this critical safety part after 7 months of waiting with no end in sight!!!
