The different possible roots and risks of smell of burnt plastic on a Nissan Navara

So we begin our content page with the different possible roots of burnt plastic smell on a Nissan Navara . Generally speaking, noticing a plastic or rubber smell is hardly ever a good signal. Obviously, modern cars are full of it and it could be the sign of a critical breakdown. Below we will review the different possible origins of burnt plastic smell:

  • Transmission oil: This is the main possible origin 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 damaged, it also has a second function as a temperature regulator. Nevertheless, as time passes, the oil will lose its efficiency and will not lubricate the parts and regulate the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Nissan Navara. 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 mainly made of rubber, will deteriorate and no longer rotate completely on its axis. With the friction that this will cause the plastic will heat up and burn out, this reaction will produce a strong smell of burnt plastic or rubber in the engine unit block of your Nissan Navara.
  • Faulty hose wear: This case occurs especially on Nissan Navara that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your car contrary to what you might presume will cause the plastic parts to wear out more fairly quickly. Hoses are the first to be troubled by this phenomenon. The rubber will disintegrate little by little and with the rise in heat of the fluid that circulates in it, it may melt. The risk of this issue is the breakage of the accessory belt.
  • A body component: Less common, especially present on Nissan Navara’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body parts that may have been bent may rub against one of your wheels and give off that burnt plastic smell. This may also pre-wear out your tyres.
