Problem with Marazzo

Problem with Marazzo

The vehicle is all good in city and Highway, good interior and suspension. But the vehicle struggles at high altitude like Shimla, the vehicle used to go down the opposite way if the ac is on and the vehicle is filled. We had put rocks and on full acceleration in 1st gear hardly pulled the vehicle. We struggled a lot if the vehicle stops at a slope in traffic the vehicle will go back and hit the other vehicle behind. I personally think there is a clutch issue with every Marazzo. Because I found a similar case with another Marazzo.
