While driving at interstate highway speed at approximately 70 mph in heavy rush hour traffic, the vehicle suddenly made a popping sound and immediately lost all engine power. The accelerator became unresponsive, and the vehicle rapidly decelerated without warning. I was forced to coast across lanes to the shoulder to avoid a collision. The engine shut down completely and the vehicle would not restart. This created a serious risk of injury or death due to loss of power in high-speed traffic. The vehicle had to be towed and is currently undrivable. Prior to this incident, the vehicle had a long history of repeated engine misfires. Spark plugs were replaced twice, and a fuel line repair was performed. Despite these repairs, the misfires continued. The sudden engine shutdown occurred without warning.
