Jun 22, 2026AirbagsSeat beltsCrash

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.

This concerns our 2016 Buick LaCrosse. We leased the car late in 2016 for 3-1/2 years, then purchased it including an extended warranty. Two problems occurred. First the fuel supply line to the engine began leaking, leaving a gasoline odor inside the car. We took the car to our dealership and had it repaired. We told the dealership we purchased an extended warranty with the car and were told this repair was not covered! We had to pay ±$471 out of pocket which we don't agree with. The second issue is the Return fuel supply line which let loose when starting the car, (weeks later) spraying gas all over the garage floor. I opened the hood to check the problem and tried starting the engine again. There was a small fire which I extinguished immediately. We had to have the car towed to the dealership to get it repaired a second time for fuel line issues. This time it cost us ±$978 out of pocket to get it fixed. They said again extended warranty did NOT cover this problem. I am told by a GM executive that GM has a separate warranty (10yr) for EPA fuel & emissions compliance that should have covered this situation, yet the dealer charged us for the repairs. I have also heard that NHTSA has a similar regulation which I would like to know more about.

RENTED AUTO FROM ENTERPRISE LEASING COMPANY OF ST. LOUIS, DROVE 412 MILES WITH THE SEAT HEATERS ON. WHEN I GOT OUT OF THE CAR I FELT AN INTENSE BURNING SENSATION ON MY LOWER BACK. BEFORE BED MY HUSBAND LOOKED AT IT AND SAID IT WAS VERY VERY RED. I AM A BACK SLEEPER SO I HAD A VERY RESTLESS NIGHT. BY THE NEXT MORNING THE RED SPOTS HAD BLISTERED AND ARE PAINFUL. I CALLED GM CUSTOMER SERVICE TO REPORT THE INCIDENT AND THEY TOLD ME THAT I WOULD HAVE TO TALK TO ENTERPRISE LEASING COMPANY OF ST. LOUIS; WHICH IS JUST RIDICULOUS - ENTERPRISE DID NOT MAKE THE CAR! EVENTUALLY I WAS GIVEN CASE NUMBER 8-1897481531. I HAVE READ OTHER REPORTS OF GM BEING SUED FOR BURNS FROM SEAT HEATERS, GM SHOULD BE REQUIRED TO INSTALL A SAFETY FEATURE TO PROTECT CONSUMERS FROM THIS FEATURE.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2016 Buick Lacrosse verdict →
