2016 Buick Lacrosse

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.

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.

I lost power steering while driving 70 mph on a two-lane highway in Wyoming. There were no warnings before the incident, but a Service Power Steering light came on at the same time it quit working. One mechanic shop did a diagnosis on the car. I was told that the Electric Gear Power Steering Motor needs to be replaced along the whole Rack and Pinion that it's attached to has to be replaced because of the way it's designed. I found out that 2,000 of these same model and year of cars had a recall on them for this exact problem, but my car's VIN wasn't included in that recall. After doing thorough research on the internet, I have found that this is a common issue with these cars, and it's obvious that the manufacturer should have included more cars in the recall. I have just turned 77,000 miles on my car, and I have been given a $4,000 estimate to get it repaired. It is completely undrivable at this time.

While navigating a curve, my power steering quit, nearly causing me to hit an oncoming car in the opposite lane. I stop and search the car for issues but found none. The care returned to normal steering and two days later, I had a vehicle pull out in front of me, while quickly avoiding the other car, my power steering quit working again. Luckily, I was able to overcome the steering but it certainly shocked me. This is a most definite safety concern that must be looked at closer before someone seriously gets hurt.

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 driving on a main street. Received Power Steering Fluid message and then steering well locked up. Could not manuever it. Had to pull over to call for assistance, to no avail. The manual states it is a electrical power issue. I've taken this car in numerous of times for various services, specially the "jerking" of the car. I've discovered there was a recall for the Power steering today was announced a few years ago but never gotten a letter to have mine checked. I just recently picked my car up from servicing and there is no notation of needing power steering fluid. I feel like this is a dangerous issue especially if had locked up on the highway!

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.
