Indeed, modern vehicles are full of it and it could be the sign of a major breakdown. Below we will talk about the different possible origins of burnt plastic smell:
- Transmission oil: This is the most important possible origin of such an odor. Indeed, the objective 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 objective as a temperature regulator. However, 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 Porsche Cayenne. 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 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 produce a strong smell of burnt plastic or rubber in the engine block of your Porsche Cayenne.

In fact, storing your car contrary to what you might presume will bring about 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 may possibly melt. The risk of this problem is the breakage of the accessory belt.
- A body component: Less basic, specifically present on Porsche Cayenne’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.
