What owners report

I had an accident in dec 2016 and the air bags didn't deploy. I had a pretty severe wreck running into 3 vehicles with substantial front end damage including broken tire rod. Below is just a picture of the damage. Body shop was in disbelief that the airbags didn't deploy??
Air bags · crash · 2019-04-28 · NHTSA complaint #11204291
Vehicle shut off while driving on the highway. No warning signals and happened multiple times over the course of the day. Speed was 70 mph
Electrical system · 2020-01-26 · NHTSA complaint #11302086
Two weeks after that I broke down (stalled out in the road) due to 2 lifters collapsing and the camshaft being damaged. After replacing all lifters, the camshaft, spark plugs and wires, as well as another oil pressure sensor just in case the other one was bad I still have low oil pressure. This cost $3,000.00!

My dash has been slowly cracking, the crack is now in two places, by the air bag and steering wheel and has completely released so it vibrates the whole time I'm driving. Just this week the airbag light is now coming on too.

While driving the vehicle, the door locks began to cycle, nav system and radio on and off. After stopped, remote car lock inoperative, tried to start vehicle and there was no indication of any electrical power with the key on....I thought is was a dead battery.
Electrical system · 2018-10-29 · NHTSA complaint #11143669
The seat heater in the rear right seat overheated and caught on fire while my 10 yr. Old child was seated in it. We were in motion at the time on the interstate. I believe the heat mechanism failed and overheated and would not shut off causing the cushion to catch on fire.
Electrical system · 2018-01-24 · NHTSA complaint #11064603
No in addition to the large crack, the dash board now rattles. I do not have pictures handy during the time of this submitter but I can provide them. 100's of other have also had this problem, there are facebook pages and various pertitions.
Structure · 2017-06-15 · NHTSA complaint #10995285
The crack gets worse every day due to the continuous vibrating of the entire dashboard while driving. Please remedy this before someone gets severely injured or worse. This is a family vehicle, mostly driven by families with 3 or more children, please consider this strongly and fix this problem immediately.
