While traveling 40mph and as a result of an accident air bags did not deploy, causing injury. Please provide further information.
When applying brakes in normal conditions, the brakes failed to stop the vehicle, causing an accident. Please provide details.
Vehicle's shoulder harness allows the passenger to make the shoulder harness loose against the body instead of firm, resulting in the person being thrown about on serious impact in the vehicle. Dealer was contacted and cannot duplicate the problem.
Deer jumped in front of the car and totaled the car, air bags did not deploy.
Drivers seat back designed to collapse upon rear impact, making it impossible to see/control the vehicle.
When vehicle hit in rear, driver's seat back reclined, causing driver to lose control of vehicle and hit vehicle in front/injury.
The trunk does not open from the inside or out, with key or without, malfunction or defect in assembly of vehicle. I took the auto to the dealership (turlock - smith chevrolet cadillac, inc.) and was charged for them to look at the problem and they attempted to break into the trunk without success.
