The different possible origins and risks of smell of burnt plastic on a Ford Fiesta

So we start our content page with the different possible origins of burnt plastic smell on a Ford Fiesta . Generally speaking, noticing a plastic or rubber smell is never a good signal. Indeed, modern cars are full of it and it could be the sign of a major malfunction. Down below we will review the different possible origins of burnt plastic smell:

  • Transmission oil: This is the most important possible source of such an odor. Indeed, 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, with time, the oil will lose its performance and will not lubricate the auto parts and regulate the temperature as well, which will bring about the oil to overheat and thus give off that burnt plastic smell on your Ford Fiesta. 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 deteriorate and no longer rotate entirely on its axis. With the friction that this will bring about 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 Ford Fiesta.
  • Faulty hose wear: This circumstance occurs specifically on Ford Fiesta that are starting to get a few years old or that have stayed a long time without rolling. In fact, storing your car contrary to what you might presume will bring about the plastic auto parts to wear out more fairly quickly. Hoses are the first to be suffering from 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 Ford Fiesta’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.
