same for me, my 2014 glx have this 2 problem and SC never have solution. Rattle sound they just open and fix back where the part u complaint have sound, but it never a permanent solution.
For the burning smell, they keep said never heard ppl complaint abt this issue and i'm the first one. Btw, i'm from penang, anyone know any solution please tell me.

I do a research, all the info from oversea. some said cat converter causing this, some said transmission fluid overflow causing this, some said plastic wire near to engine manifold melt causing this.... all and all I check, no overflow, no nearby plastic/wire melt, cat converter>> cant try.

my car still under warranty, have to use ori part from Suzuki. Btw, I just have my 20k service and change the aircon filter, cost me RM150. They also claim anti bacteria and so on, but I still can smell the burning/ alcohol rubbing smell now even not rev at highway.

Hi, I own the 2014 GLX swift. Recently my car also experience this kind of sound but in difference condition. The sound happened only when driving on certain road with the car in moving condition with either aircon on/off. I'm not sure are we refer to the same symptom but do you manage to find out what going on with your car?
