Hi,

I bought Vitara S BoosterJet 6 months ago and everything was perfect until last week. I noticed vibrations/resonance around 2000rpm when the engine is cold, video with the sound is available here, headphones needed because it's not loud. Catalytic converter was changed in the Official Suzuki service because catalytic converter carrier was broken, but this didn't solve the problem.

Any similar issues among Vitara S owners?

Many thanks Smile

As a matter of interest does it happen in all gears at 2000 rpm ?

Unfortunately didn't have a chance to test it in 5th or 6th gear because the engine heats up until I reach high-speed road. It definitely happens in 1-4 gear and also neutral (shown in the linked video).

How strange,

Any power loss at all?

You should be getting full boost from 1500rpm on, do you get any turbo whistle?

Have you checked things like loose air box or engine covers?

Haven't noticed any power loss, there is characteristic turbo kick. Everything seems well fastened under the hood.

The problem occurred with the first outside temperature drop i.e. I noticed the problem when the outside temperature dropped to 10ºC. When the engine heats up everything sounds normal but when it's cold it makes this resonance noise. Didn't have any problems during the summer.

Visited the dealer today but they were unable to reproduce the vibrations because the outside temperature was almost 19ºC...
Could you please confirm that you don't hear any vibrations around 2000 rpm when the outside temperature is below 10ºC? Many thanks Smile

Hi,

I've driven the past month constantly below 10ºC, often below zero. Haven't noticed any vibrations.

Nothing, it's been between 0 and 13 degrees here this past week and it's all been fine.
