The different possible roots and risks of smell of burnt plastic on a Infiniti QX50
So we commence our article content with the different possible roots of burnt plastic smell on a Infiniti QX50 . Generally speaking, noticing a plastic or rubber smell is never a good indicator. Indeed, recent cars are full of it and it could be the sign of a significant malfunction. Down below we will review the different possible origins of burnt plastic smell:
- Transmission oil: This is the main possible source of such an odor. Indeed, the function of gear or transmission oil is to lubricate the different elements of your gearbox so that all the gears and pinions are not broken, it also has a second function as a temperature regulator. Nevertheless, in the long run, the oil will lose its performance and will not lubricate the parts and control the temperature as well, which will bring about the oil to overheat and thus give off that burnt plastic smell on your Infiniti QX50. 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 mainly made of rubber, will deteriorate and no longer rotate totally on its axis. With the friction that this will bring about the plastic will heat up and burn out, this reaction will produce a strong smell of burnt plastic or rubber in the engine unit block of your Infiniti QX50.
- Faulty hose wear: This circumstance occurs especially on Infiniti QX50 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 bring about the plastic 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 problem is the breakage of the accessory belt.
- A body component: Less common, especially present on Infiniti QX50’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body parts that may possibly have been bent may possibly rub against one of your wheels and give off that burnt plastic smell. This may also pre-wear out your tyres.
