Obviously, modern vehicles are full of it and it could be the sign of a critical breakdown. Below we will review 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 also has a second function as a temperature regulator. Nevertheless, over time, the oil will lose its performance and will not lubricate the parts and regulate the temperature as well, which will trigger the oil to overheat and thus give off that burnt plastic smell on your Mercedes Benz GLA Class. 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 trigger 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 Mercedes Benz GLA Class.
  • Faulty hose wear: This circumstance occurs specifically on Mercedes Benz GLA Class that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your car contrary to what you might believe will trigger the plastic 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 might melt. The risk of this issue is the breakage of the accessory belt.
  • A body component: Less basic, specifically present on Mercedes Benz GLA Class’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.
