The different possible sources and risks of smell of burnt plastic on a Lexus CT

So we start our content with the different possible sources of burnt plastic smell on a Lexus CT . In general, noticing a plastic or rubber smell is never a good signal. Indeed, recent vehicles are full of it and it could be the sign of a major malfunction. Down below we will talk about the different possible origins of burnt plastic smell:

  • Transmission oil: This is the main 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 also has a second action as a temperature regulator. However, in the long run, the oil will lose its effectiveness and will not lubricate the parts and regulate the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Lexus CT. 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 degrade 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 create a strong smell of burnt plastic or rubber in the engine unit block of your Lexus CT.
  • Faulty hose wear: This case arises specifically on Lexus CT 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 believe will cause 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 general, specifically present on Lexus CT’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. This may also pre-wear out your tyres.
