Example complaints
Brakes: “Our 1994 Gmc jimmy was being driven by my wife and had my two children inside. She exited the parking lot of the local food store. After crossing to the opposite side of the street, she noticed traffic stopped ahead for the upcoming stoplight. She applied the brakes, but nothing happened, and she started a four car chain reaction. This resulted in the damage of four vehicles and three emergency room visits. (includung my son, who hit & broke the windshield). It appears that everyone is o.k. At this point, all leaving under their own power. …”
