I was driving my vehicle and exiting the hw. The rear wheel of the driver side broke off and separated from the car which caused my car to hit the cement beerier on front and the side of the driver side of the vehicle. Then the car turned 180 degrees and hit the beerier on the passenger side and the rear of the car. The air bags never deployed and we discovered that the wheel brook off of the rear axe. No damage to the wheel. Several industry exports stated that this should never happen.
I was driving a 2018 GMC Yukon denali, braking/slowed to about 8 mph for traffic jam, when rear ended at approximately 55 mph by a 2000 Buick lesabre. Rear end collision launched my 2018 GMC Yukon denali, at approximately 45 mph into stopped vehicle ahead of me, a 2010 Jeep commander which was completely stopped in traffic. Jeep commander was propelled into 2015 Nissan xterra, also stopped in traffic. None of the airbags in my 2018 GMC Yukon denali deployed either in the rear end impact, nor the front impact of my vehicle hitting the Jeep commander. Accident was on Sunday, 04-21-2019 at approximately 01:30 pm mst. Skies were partly sunny and road had minimal wet area from earlier sun shower. Airbags should have deployed in both collisions, yet did not. I am extremely agitated about my airbags not deploying.
