Hi, with regards to this sudden acceleration, my advice is to check the car rug. If you buy rugs, find something suitable that doesnt reach the pedals and should be secured in place so that it will not move around. I had a situation like this with my Montero here in DOHA but it's Pajero Sport cause it's bit wide and taller and has a bigger engine V6 3.5L. I stepped of the break then it accelerates, so i shift the gear to N right away and checked it which i found out that the carpet was hitting the gas pedal. As a safety precaution, as you sit inside the vehicle, safety belt first, mirrors, step and check the pedals, gear should be P and hand break should be engaged before starting the engine. Step on break when you start the engine, shift the gear to (D) Drive while stepping on the break, let go the hand break then slowly let go the foot break till it moves gently before you step on the gas pedal. If you're used to doing this routine, that type of situation can be avoided.
