Scared to drive been crying every day the front airbags did not come out Has the problem been reproduced or confirmed by a dealer or independent service center? waiting on the insurance to review Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? By Police and Tow Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes, a same concern when driving in rain, or any time the road is not dry the car will slide, I have no control over the back of the car it slides often and i will have to correct it”
