Mr. Did evasive manuevers at 65 MPH to avoid deadly collision with fully loaded senior citizen van by a driver with a cell phone. Steering wheel was very loose, brakes pedals were very easily depressed, none of the front air-bags deployed and car seats did not lock. Mr. Hit median concrete at 60 MPH. Ambulance and emergency room dictated, "you all very lucky to have survived." 3rd party administrator(esis) counter claims mr.. That because mr. Collided with median sideways the air-bags did not deploy. Mr. Argues that front driver portion of car hit median first, air bags should have deployed and seat belts should have locked. 3rd party administrator counters. Because there is no proof we cannot claim such fact. She (3rd party) is insisting on us to sign medical release forms and submit pictures of car. Mr. Has advised that car is repaired and has been sold. …

Re: Pontiac 2006 -G6 gt elect. System, elect. Stability control, exterior lighting, service brakes, hydraulic, vehicle speed control --- this car was recalled for above problems in 2014. At that time I brought car to dealer to be fixed, although the car was not in need of repair because no problems had existed, dealer stated he fixed all recall problems at that time. Now two years later I am experiencing all the listed problems above. I took car to mechanic where he did replace parts but still experiencing problem. It must go back to dealer so problem can be alleviated. Brake lights do not go on when braking also when applying gas they sometimes go on. Cruise control is also not working. What's to say that this problem was never fixed in 2014 when the car was recalled due to the fact that I wasn't having any issues at that time. …
