The different possible sources and risks of smell of burnt plastic on a GMC Yukon XL

So we commence our content page with the different possible sources of burnt plastic smell on a GMC Yukon XL . Generally, noticing a plastic or rubber smell is hardly ever a good indicator. Indeed, recent vehicles are full of it and it could be the sign of a important malfunction. 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. Indeed, the action 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 as well has a second action 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 GMC Yukon XL. 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 mainly done 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 produce a strong smell of burnt plastic or rubber in the engine block of your GMC Yukon XL.
  • Faulty hose wear: This circumstance occurs specifically on GMC Yukon XL that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your car unlike what you might think will cause the plastic auto parts to wear out more 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 possibly melt. The risk of this issue is the breakage of the accessory belt.
  • A body component: Less common, specifically present on GMC Yukon XL’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.
