While driving my 2006 Mitsubishi Raider, I was leaving a customers home with a load on my truck. The first issue I encountered was that the truck struggled to exit the driveway. Then, I realized I couldn’t shift into reverse. Shortly after, it seemed like the gas line or speed mechanism malfunctioned. Suddenly, the truck accelerated uncontrollably, going full speed straight into a house.luckily I braked in time no accident no report just towed truck tó customers house with aaa after the incident
