“Brake system failure: I was driving on the highway and had to execute an emergency stop going approximately 30 MPH on a cool dry road. When I did, the car power, engine, electrical system shut down and refused to brake any more than it did prior to my slamming on the brakes. My momentum would have carried me into the car positioned only a few feet in front of me if I hadn't the presence of mind to instinctively pull off onto the shoulder as to avoid rear-ending the car in front of me. I had to put the car into park in order to be restart it. …”

“I just purchased this car in february 2019 and it went down in late april or early may of this year. The service engine light would come on for a few days then it would go off for a few days. The engine would rattle when first cranked and then it got to the point where it would constantly keep trying to crank but never would and now it is completely out. I had it towed to mechanic and was told that they had to put 5 quarts of oil in it but I had the oil changed a month before the car died. They say the oil is going somewhere but where? I was also told the timing chain had failed. …”

“A few weeks after my latest oil change I was driving on the freeway in semi crowded conditions when the car started bucking. The car slowed and I had to avoid traffic and almost was hit as the car would not respond, was scared to death. I thought it was a transmission issue but when I called the mechanic he knew what it was right away, he said check your oil and I did and it was near empty. No oil in my garage, no oil in my work parking spot, no visible leaks, but all the oil gone. …”

“I was traveling approximately 65 MPH on a 3 lane highway, while mainitaning a constant speed. Suddenly all power to the vehicle cut off including my power steering and braking. In a panic as I as coasting I was fortune enough to weave my way across 2 lanes to the side of the highway and roll to a complete start. After gathering myself I turned the ignition from the run position to off. I looked up and noticed there was smoke coming out from under the hood. I jumped out, lifted the hood, and heard popping and steam/smoke rising up from underneath the engine by the firewall. …”
