My vehicle was in motion on a city street. i went to make a turn because of a curve and my steering wheel and brake would not work. my emergency brake system (which is suppose to stop my vehicle before impact, did not deploy. i ran straight into a stone wall and fence. i received a recall letter in the mail about the back sensor, but my sensors were working up until my accident. my vehicle was deemed totalled. it was not raining, i was not speeding, and when the police came out to do an investigation, they could only determine that it was a mechanical problem. why did the sensor not work? why didn't my cars emergency brake system not work? now i'm having to get a new vehicle without even knowing why the safety systems put in place did not deploy. thank god my son was not in the car and no one else was injured.
