With the friction that this will trigger the plastic will heat up and burn out, this reaction will create a strong smell of burnt plastic or rubber in the engine unit block of your Toyota Yaris.
  • Faulty hose wear: This circumstance occurs especially on Toyota Yaris 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 trigger 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 may possibly melt. The risk of this issue is the breakage of the accessory belt.
  • A body component: Less basic, especially present on Toyota Yaris’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.
