The different possible sources and risks of smell of burnt plastic on a Suzuki Swift

So we start our guideline with the different possible sources of burnt plastic smell on a Suzuki Swift . Generally, noticing a plastic or rubber smell is hardly ever a good indicator. Indeed, recent cars are full of it and it could be the sign of a critical breakdown. Down below we will review the different possible origins of burnt plastic smell:

  • Transmission oil: This is the most important possible origin of such an odor. Indeed, the action of gear or transmission oil is to lubricate the different elements of your gearbox so that all the gears and pinions are not broken, it as well has a second action as a temperature regulator. Nevertheless, over time, the oil will lose its performance and will not lubricate the parts and control the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Suzuki Swift. You risk pre-wearing your gearbox if you don’t take care of it.
  • The accessory belt: Although rarer, it is possible with wear and tear that your belt, which is specifically made of rubber, will deteriorate and no longer rotate totally on its axis. With the friction that this will cause the plastic will heat up and burn out, this reaction will generate a strong smell of burnt plastic or rubber in the engine unit block of your Suzuki Swift.
  • Defective hose wear: This case arises especially on Suzuki Swift that are starting to get a few years old or that have stayed a long time without rolling. In fact, storing your vehicle contrary to what you might presume will cause the plastic parts to wear out more quickly. Hoses are the first to be suffering from this phenomenon. The rubber will disintegrate little by little and with the rise in heat of the fluid that circulates in it, it might melt. The risk of this issue is the breakage of the accessory belt.
  • A body component: Less general, especially present on Suzuki Swift’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body parts that might have been bent might rub against one of your wheels and give off that burnt plastic smell. This may as well pre-wear out your tyres.
