Despite often being presented as mechanically simpler machines requiring minimal maintenance, electric vehicles (EVs) are experiencing surprisingly high failure rates in mandatory inspections. A key factor often overlooked by drivers is contributing to this trend.
Recent statistics from the British agency DVSA reveal that battery-powered vehicles account for half of the ten models with the worst first-time inspection pass rates. This finding raises questions about whether current-generation electric cars are truly as low-maintenance as automakers often claim.
The unexpectedly high failure rates are prompting a reevaluation of vehicle inspection standards as the automotive industry transitions towards electrification.
High-Conclude Vehicles Lagging
Perhaps the most surprising result of the data is the performance of the Mercedes-Benz EQC. The premium electric SUV, priced in line with luxury sedans, has shown a frequent failure rate on inspections. Analysis indicates that more than 17% of these vehicles did not pass their first inspection three years after registration.
Tesla models also posted unfavorable results. The popular Model Y and Model 3 had a failure rate of nearly 15% on first inspection, placing them among the least reliable cars during initial technical control. BMW i4 and the Citroën E-C4 electric crossover also appeared among the problematic models.
Tires, Not Motors, Are the Primary Issue
Experts emphasize that batteries and electric motors themselves are not causing the inspection failures. The root causes lie in the laws of physics.
A key factor is excessive tire wear, which is 40% more common in EVs than in vehicles with internal combustion engines. This is due to the combination of the weight of the batteries and the instant torque delivery.
Because EVs can transfer significant power to the road almost instantly, tire tread wears down rapidly, often falling below the legal limit of 1.6 millimeters before owners realize a replacement is needed.
Changes to Vehicle Inspections Under Consideration
Given the specific challenges EVs present, discussions are underway in the European Union and other countries regarding adjustments to vehicle inspection rules.
Current methodologies were designed for the era of gasoline and diesel and do not adequately account for how modern EVs function.
Inspections should focus more on software, the functionality of advanced driver-assistance systems, and the safety features of electric drivetrains. The goal is to adapt legislation to reflect current realities. It’s no longer just about tires; cars are increasingly becoming computers on wheels, and the laws aren’t prepared.
Preparation is Key to Passing Inspection
When selecting a vehicle, it’s important to consider its reliability and the satisfaction of other drivers. Objective indicators include results from technical inspections. While several electric vehicles have ranked highly, this doesn’t mean they should be dismissed.
Drivers also must remember that EVs are different, including the tire wear issue. However, proper preparation remains essential to avoid failing an inspection.
