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

So we start our content page with the different possible roots of burnt plastic smell on a Nissan Murano . Generally speaking, noticing a plastic or rubber smell is hardly ever a good sign. Obviously, recent vehicles are full of it and it could be the sign of a major breakdown. Down below we will talk about the different possible origins of burnt plastic smell:

  • Transmission oil: This is the most important possible origin of such an odor. Obviously, the function of gear or transmission oil is to lubricate the different components of your gearbox so that all the gears and pinions are not damaged, it as well has a second function as a temperature regulator. However, over time, 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 Murano. You risk pre-wearing your gearbox if you don’t take care of it.
  • The accessory belt: Nevertheless rarer, it is possible with wear and tear that your belt, which is principally made of rubber, will decline 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 generate a strong smell of burnt plastic or rubber in the engine unit block of your Nissan Murano.
  • Faulty hose wear: This circumstance happens specifically on Nissan Murano 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 presume will cause the plastic parts to wear out more quickly. Hoses are the first to be impacted 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 possibly melt. The risk of this problem is the breakage of the accessory belt.
  • A body component: Less general, specifically present on Nissan Murano’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body 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.
