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 occasionally while his wife was driving in rainy or snowy conditions, the check power steering warning light illuminated. The contact stated that after it had stopped raining or snowing, the vehicle regained power steering functionality. The contact stated that the failure had occurred on several occasions. The contact stated that a dealer was not contacted. The vehicle was taken to a dealer where it was diagnosed; however, the diagnostic result was unknown.

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.

Cars shudders 20-30 MPH. Started last year, I needed to get my wife for cancer treatments. Basically, shifted the car manually.

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.

THE PASSENGER SIDE POWER MIRROR CHANGES POSITION BY ITSELF. ALSO WHEN I HIT A BAD BUMP OR POTHOLE THE DOORS UNLOCK

SEVERAL TIMES WHILE DRIVING IN HUMID WEATHER, THE INSIDE OF THE WINDSHIELD HAS QUICKLY FOGGED UP TO THE POINT OF BLINDING ME. THE DEFROSTERS ARE SHOOTING A FOG OF MOISTURE ONTO THE GLASS. I TOOK THE CAR BACK TO THE DEALER TO HAVE THE HVAC CHECKED AND THEY TOLD ME THAT THIS CONDITION WAS NORMAL. SEEMS DANGEROUS TO ME?

AS I WAS HEADING OUT OF TOWN FOR MY DAILY COMMUTE TO WORK I HEARD A LOUD POP NOISE. I LOOKED UP AND NOTICED MY SUNROOF HAD EXPLODED ABOVE ME. I WAS GOING ABOUT 40 MPH AND HAD NO TRAFFIC AROUND ME. I TURNED AROUND AND HEADED BACK HOME WHERE I NOTICED THAT THE GLASS WAS BENT UPWARD AS IF THERE WAS TOO MUCH PRESSURE IN THE CABIN. I TOOK THE CAR TO THE DEALERSHIP AND THEY SAID SOMETHING HAD TO OF HIT IT WHICH I DO NOT BELIEVE BECAUSE THERE WAS NO TRAFFIC AROUND ME AND THE HOLE WAS ABOUT 1FT BY 1FT WITH THE GLASS BENT UPWARD AS IF IT WAS SOMETHING FROM THE INSIDE THAT CAUSED IT TO EXPLODE. I LOOKED UP ON LINE AND NOTICED THAT THE 2015 BUICK REGAL AND CHEVY CRUZE BOTH HAD TO HAVE RECALLS WHERE THEY REPLACED THIN GLASS IN SUNROOFS. TO ME IT APPEARS THIS IS THE CASE FOR MY 2016 BUICK LACROSSE WHERE THE GLASS WAS TOO THIN.

LOTS OF CONDENSATION IN RIGHT HEADLIGHT

Vogue Custom Built Radial VIII Tire size: 235/50/18 While driving on the Highway, I experienced a Tire blowout on my front passenger side of the vehicle that also led to vehicle damage. I have pictures of the tire post blowout with a gaping hole in the middle of the tire and the tread completely fallen off. This Incident put my life and others at risk as I was forced to pull my vehicle to the side border of the highway to avoid incoming traffic. This Incident occurred 7 months after I had my tires serviced at my local tire shop where they verified that 2 of the 4 tires were experiencing splitting on the sidewall and tread. I got those 2 tires replaced with the same vogue tires and they were moved to the back of the vehicle. The other 2 tires were ok to drive on. This background information highlights what I believe is a manufacturer's defect with the tendency that these Vogue tires have to split and deteriorate. I believe that the front passenger tire that blew out on the highway, likely experienced the same effects that required me to replace 2 of the tires just 7 months ago. These tires are dangerous for anyone to drive on due to this manufacturer's defect. They have less than 60,000 miles of mileage on them, they were properly inflated, and I did not receive any vehicle warning signs or see any indicators on the exterior of the tire. I am also a person that services their vehicle routinely. My hope is to help others avoid the risks that come with these tires which could have cost myself and others their lives.
