The different possible roots and risks of smell of burnt plastic on a Jeep Grand Cherokee

So we commence our guideline with the different possible roots of burnt plastic smell on a Jeep Grand Cherokee . Generally, noticing a plastic or rubber smell is hardly ever a good indicator. Obviously, recent vehicles are full of it and it could be the sign of a critical malfunction. Below we will talk about 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 components of your gearbox so that all the gears and pinions are not broken, 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 control the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Jeep Grand Cherokee. 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 cause the plastic will heat up and burn out, this reaction will create a strong smell of burnt plastic or rubber in the engine block of your Jeep Grand Cherokee.
  • Defective hose wear: This circumstance happens especially on Jeep Grand Cherokee that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your vehicle unlike what you might believe 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 might melt. The risk of this issue is the breakage of the accessory belt.
  • A body component: Less general, especially present on Jeep Grand Cherokee’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.
