2006 MITSUBISHI RAIDER Engine Problems

While driving my 2006 Mitsubishi Raider, I was leaving a customer’s 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

3 TRANSMISSIONS ALREADY AND IT'S ALREADY SHIFTING HARD

1.THE CAR STOP ENGINE SUDDENLY ON THE FREEWAY 5 SOUTH NEAR CULVER EXIT. 2. IT STOPPED GARDEN GROVE BLVD AND ECULID ST IN GARDEN GROVE CITY CA ABOUT FEW MONTH LATER WHEN I TRIED TO MAKE LEFT TURN, THE ENGINE STOPPED. 3. IT STOP AGAIN ON 22 FWY . 4. ONE MORE STOPPED NEAR 55 FWY AND DYER AVE, ENGINE TOTALLY STOPPED, BUT I COULD START AND DRIVE AFTER THESE INCIDENTS. THE OTHER PROBLEM IS THE IGNITION BLOCKED TURN THE ENGINE START. THE KEY DOESN'T MOVE SO FREQUENTLY. MY CAR MILEAGE IS JUST OVER 50,000 MILES. WHAT IS THE PROBLEM? I PURCHASED THIS USED CAR FROM UNION AUTO IN GARDEN GROVE THE MILEAGE WAS ABOUT 16,000 MILE. *TR
