I bought my nissan micra in nov. 2012and suddenly it came with 2 problems. I was really shocked by seeing this how can such problems occur in new car. My micra faced the problems :-
1. Loud noise while driving.
2. Emitting a lot of black smoke.
is there any solution for that?
You are in tough situation karanjeet but you have not mentioned which car is it, is it Diesel version or it is petrol version ?
Assuming its diesel then first check your airfilter , if it is not clean then clean it or if time to replace then replace it.
Regarding noise, you have not mentioned what kind of noise, from engine from tyres or where its coming ?
