In fact, recent vehicles are full of it and it could be the sign of a critical malfunction. Below we will review the different possible origins of burnt plastic smell:

  • Transmission oil: This is the main possible origin of such an odor. In fact, 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 effectiveness and will not lubricate the auto parts and regulate the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Jeep Liberty. 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 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 produce a strong smell of burnt plastic or rubber in the engine unit block of your Jeep Liberty.
  • Defective hose wear: This circumstance arises specifically on Jeep Liberty that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your vehicle contrary to what you might think will cause the plastic auto 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 problem is the breakage of the accessory belt.
  • A body component: Less general, specifically present on Jeep Liberty’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body auto 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.
