Are EVs unreliable?

Some media sources claim that EVs are less reliable than petrol or diesel vehicles. 

However, the MOT failure rate for EVs is currently far less than petrol vehicles - data from the DVSA shows that just 14.84% of hybrid cars and 17.87% of electric cars failed their MOT between 2019 and 2021, compared to 20.07% of petrol vehicles and  23.11% of diesels.

An electric vehicle has far less mechanical moving parts than a conventional engine, meaning that they are generally easier to repair and less likely to fail an MOT. Petrol and diesel vehicles are subject to checks on fuel lines, catalytic converters and particulate filters; because EVs have none of these parts, there are simply fewer parts to need replacing.

It’s important to note that EVs can require slightly more frequency tyre changes than petrol and diesel cars - as electric vehicles tend to be heavier due to the weight of their battery, this can accelerate tyre wear and tear.
