2016 Buick Lacrosse problems

“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.”

“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. OnStar was contacted and informed the contact that a DTC for the ABS was found. The vehicle was taken to an independent mechanic, where it was repaired for ABS failure; however, the failure persisted. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was test-driven. The mechanic diagnosed the vehicle and determined that the transmission had failed and needed to be replaced. The contact stated that the transmission was previously replaced twice due to the failure. The mechanic advised the contact to get rid of the vehicle. The vehicle was not yet repaired. The dealer and the manufacturer were not notified of the failures. The failure mileage was approximately 99,000.”

“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.”

“TL* THE CONTACT OWNS A 2016 BUICK LACROSSE. WHILE THE VEHICLE WAS IN REVERSE, THE CONTACT ATTEMPTED TO SHIFT INTO DRIVE, BUT THE VEHICLE FAILED TO MOVE FORWARD. IN ADDITION, WHILE ACCELERATING FROM A STOP, THE VEHICLE FAILED TO MOVE FORWARD. ALL THE WARNING INDICATORS ILLUMINATED ON THE INSTRUMENT PANEL, INCLUDING THE CHECK ENGINE WRENCH, TRACTION CONTROL, AND STABILITRAK. IN ADDITION, THE SPEEDOMETER AND TEMPERATURE INDICATORS WOULD GO TO ZERO. ALSO, WHEN DRIVING 50 MPH, THE RPMS WOULD GO UP AND DOWN. THE CONTACT STATED THAT THE VEHICLE WAS TAKEN TO TEXAN GMC BUICK (18225 EASTEX FWY, HUMBLE, TX 77338, (281) 973-3117) SIX TIMES WHERE IT WAS DIAGNOSED THAT MULTIPLE FAILURE CODES WERE FOUND AND THERE WAS A LOSS OF COMMUNICATION. THE DEALER PERFORMED A CALIBRATION AND CLEARED ALL THE CODES. THE VEHICLE WAS TEST DRIVEN AND ALL THE GAUGES WERE AT ZERO. THE FOLLOWING FAILURE CODES WERE FOUND: U0100-U2099-U0140-U0120 (STORED IN TRANS, BCM, PARK BRAKE, FUEL PUMP CONTROL MODULE, ENGINE CONTROL MODULE FAILING INTERMITTENTLY, REPLACE ENGINE CONTROL MODULE ASSEMBLY, PERFORMED PROGRAMMING AND MOBILIZER LEARN AND SETUP PROCEDURES, CLEAR FAULT, AND ROAD TEST). THE FAILURE…”

“Adaptive cruise control dropped out, taking along with it the ABS (warning light), Stabilitrak (handling system) (warning light), Collision prep (message). Dealer states the ABS computer module failed, now in process of finding a replacement. Meanwhile, the ABS, cruise control, and other systems mentioned here are inoperative. It may well be that this may be considered to be a component failure, not an inherent safety issue but under some driving conditions it is clearly a safety consideration.”

“I was in a front end collision where the damages were over $20,000.00 and the air bags did not deploy.”
