Heard snap while driving hit median,and totaled my truck.it needs to be noticed if any body hasn't been killed yet
The air bags did not deploy. A police report was filed and the vehicle was towed. The contact sustained minor injuries, but did not require medical attention. The contact, a licensed mechanic, diagnosed that the brake line was corroded and needed to be replaced. The vehicle was not repaired.
The service shop showed me the heavily rusted and pitted brake lines. They failed in areas at the bend that were subject to salt exposure. The shop said the metal brake lines all have to be replaced.
The vehicles governor shut the vehicle off at 97mph while going around a corner which made the steering wheel lock up and made the brakes not work. Two people where life flighted to hospitals with various injuries... No air bags deployed at all... The first impact in the accident was to the side of the vehicle.
Recently my 2002 chevrolet avalanche has begun to shut off while driving which causes the vehicle to lose power. Another important safety issue, the brakes began to press all the way to the floor while braking.
Son hit a tree head on totaled avalanche front end air bag did not deploy why??????????
There were no warning lights illuminated during or after the crash. The vehicle was repaired and the store sustained $1,900 worth of damage. The sudden acceleration recurred, however, the driver was able to gain control.
