I have just bought a new 2016 Nissan X-Trail.
The first problem I found while I was driving the car uphill with three adults was smoke coming out of engine bay with an accompanying smell.
The engine temp gauge was reading normal, and roadside assistance couldn't find any issue. Next day I took it to my dealer and was told it was the engine coating burning.
It happened again two days ago while driving uphill with three adults.
Secondly the car is shuddering while in Drive mode and idle. The vibration is more when the AC is on in Drive mode and sitting idle.
I took it to the dealer again they said engine mount is fine and couldn't find a fault. But they want the car booked in for a week to diagnose everything.
Has anyone else had this issue? Why this could be happening? Does this kind of vibration refer to any engine fault?
I'd question their diagnosis of the engine coating burning off; I think it could be deeper than that.
The vibration could be coming from a variety of sources on the engine and in the transmission.
The dealer is doing the correct thing in getting the car in for a proper investigation that will hopefully reveal the cause of the problems.
At this stage, as the car is new you should co-operate with the dealer while they are trying to resolve the issues, but at the same time maintain a watching brief to make sure there is a genuine attempt to fix your car.
