The different possible sources and risks of smell of burnt plastic on a Infiniti QX30

So we begin our content with the different possible sources of burnt plastic smell on a Infiniti QX30 . In general, noticing a plastic or rubber smell is hardly ever a good sign. Obviously, modern vehicles are full of it and it could be the sign of a important breakdown. Down below we will talk about the different possible origins of burnt plastic smell:

  • Transmission oil: This is the most important possible source of such an odor. Obviously, the function 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 function as a temperature regulator. Nevertheless, with time, the oil will lose its performance and will not lubricate the auto parts and regulate the temperature as well, which will bring about the oil to overheat and thus give off that burnt plastic smell on your Infiniti QX30. 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 principally done of rubber, will decline and no longer rotate totally on its axis. With the friction that this will bring about the plastic will heat up and burn out, this reaction will create a strong smell of burnt plastic or rubber in the engine unit block of your Infiniti QX30.
  • Defective hose wear: This circumstance arises specifically on Infiniti QX30 that are starting to get a few years old or that have stayed a long time without rolling. In fact, storing your vehicle unlike what you might believe will bring about the plastic auto parts to wear out more fairly 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 may possibly melt. The risk of this issue is the breakage of the accessory belt.
  • A body component: Less basic, specifically present on Infiniti QX30’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body auto parts that may possibly have been bent may possibly rub against one of your wheels and give off that burnt plastic smell. This may as well pre-wear out your tyres.
