Consumer Reports relies on hundreds of thousands of responses from motorists to draw 2 main conclusions about electric vehicle maintenance.
1 – Cheaper than for petrol models
No, the American body is not breaking open doors by claiming that an electric car costs less to maintain than its thermal equivalent. The idea of his investigators was to figure out the difference. They interviewed Jill Trotta, vice president of marketing and sales at RepairPal, the leading provider of information to consumers across the Atlantic about car interventions.
According to her, the maintenance of an electric model mainly counts the air filters that prevent external particles from entering the ventilation system, the brake pads (less often than on a thermal due to regenerative braking), tires, shocks, and components at the ball joints and tie rods.
When a heat transfer liquid is used in an electric vehicle, there is no need to change it regularly because of the absence of risk of contamination by oil or combustion by-products.
Fewer moving parts
It is because of a much lower number of moving parts that electric vehicles benefit from less burdensome maintenance procedures. The result of the survey conducted by Consumer Reports shows that the repair and maintenance budget of electric cars is divided by 2 compared to equivalent thermal models. Over the lifetime of the connected device, its owner would save on average 4,600 dollars (3,900 euros).
It would be from its 5th year that an electric car would begin to enter a phase where maintenance would be more expensive. But the annual budget to devote to it would still be only 900 dollars (765 euros), against 1,200 dollars (1,020 euros) for thermals.
After 10 years of service, the performance of the battery will have declined. Jill Trotta figures her replacement on average at 5,500 dollars (4,670 euros). Head of vehicle testing for Consumer Reports, Gabe Shenhar believes that, like a very mileage thermal model, an electric vehicle equipped with a pack that has gradually degraded can still serve as a second car in the household, for shorter trips. , without having to replace the batteries.
No particular fears, however, for the engine (6,000-9,000 dollars, or 5,095-7,640 euros) whose lifespan will most often exceed that of the car.
2 – Less and less expensive in the future
Current electric cars benefit from various technological advancements that increase their reliability and durability. With more energy capacity, batteries will start to degrade as they accumulate more miles and get older. This would delay their eventual replacement.
“Most of the high-mileage electric vehicles on the road today are first-generation models. We know from experience at Consumer Reports that new vehicle models, of all types, tend to have fewer reliability issues as manufacturers resolve issues, ”explains Gabe Shenhar.
Greater savings on maintenance are thus envisaged with the EVs that are arriving on the market, more reliable, and benefiting from an extended warranty in time and in mileage. Especially since the price of batteries continues to fall.
