Problems with 2006 Buick Rendezvous STRUCTURE

The dashboard is cracked for no apparent reason

I was driving in right lane, someone cut me off, by switching lanes & cutting in front of me as light turned green. i pressed on my brakes, which went all the way to the floor, hitting the person in front of me. i found out later that i injured my left knee, displaced my knee cap. i was traveling alone. airbags did not activate. during the second incident my daughters where traveling with me. my daughter's were with me. i enter road from right, heard a popping noise. pressed brakes which went to the floor, car seem to accelerate and i ran into the back of the car. airbags once again didn't activate. stunned from the weirdness of the incident i couldn't think. i told her i was ok. after getting back in car i was hurting & so were my daughters. life changed for us. they have back & neck issues. we see various doctors to manage pain. *tr

Tl*the contact owns a 2006 buick rendezvous. the contact heard a grinding sound and the brakes became hard when the brake pedal was depressed. the vehicle was taken to the dealer and they replaced the front and rear brakes. shortly afterward, the automatic transmission, wiring for the all-wheel drive, wiring for the speed sensors, and the rear tie rods were all replaced between 17,500 and 22,000 miles. the rear driver's side door also fell off the vehicle and was re-adjusted. the vehicle was taken to the dealer at least once a month for failed components. the failure mileage was 17,542 and current mileage was 23,126.
