A new industry report has revealed an escalation in the cost of vehicle maintenance across Europe, with hybrid and electric vehicle (EV) battery replacements emerging as the most expensive repair for drivers in 2026.
The February 2026 study, conducted by B2B automotive platform eCarsTrade, analysed 29 commonly failing car components across petrol, diesel, hybrid, and electric vehicles. By aggregating pricing data from mechanics, manufacturers, and industry databases, the report provides one of the most comprehensive snapshots yet of the real cost burden facing vehicle owners in an increasingly electrified market.
At the top of the ranking is hybrid or electric battery replacement, with an average cost of €12,500 and potential expenses reaching as high as €20,000 depending on battery capacity and vehicle model. The report highlights that battery-related issues are not only financially significant but also operationally critical, with failures capable of rendering vehicles completely unusable while sharply reducing resale value.
Despite the high costs, demand for battery-related information remains robust, with over 158,000 monthly online searches recorded. This indicates a rising awareness among EV and hybrid owners about the financial implications of long-term ownership, particularly as vehicles age beyond their warranty periods.
Traditional internal combustion engine (ICE) repairs also remain a major financial burden. Engine and cylinder replacements rank as the second most expensive repair category, with an average cost of €5,750 and a wide range extending from €1,500 to €10,000. These repairs continue to pose a significant risk to drivers, both in terms of cost and safety, with engine failure carrying a 40 per cent safety impact rating in the study.
Transmission-related issues rank third, with average repair costs of €3,500. However, the variability in pricing, ranging from €1,000 for simpler manual systems to €6,000 for complex automatic or dual-clutch transmissions, has made this category one of the most widely researched, attracting over 500,000 monthly searches from European drivers seeking clarity on potential costs.
Notably, the report reflects the growing complexity of modern vehicles, particularly as electrification accelerates. Components unique to EVs and hybrids, such as inverters, are now among the most expensive repair categories. Inverter replacements rank fourth, with an average cost of €3,450 and potential expenses climbing to €6,000. As a critical component that converts stored battery energy into usable power for electric motors, inverter failure represents a significant operational risk.
Automatic gearboxes complete the top five, with average repair costs of €2,750. With nearly 1.5 million monthly searches, this category is the most researched in the study, reflecting widespread concern among drivers about its direct impact on vehicle control and safety.
Beyond the top five, other costly repairs include heat pumps, turbochargers, infotainment systems, head gaskets, and airbags; all of which contribute to the rising cost of vehicle ownership. Heat pump repairs, for instance, average €2,600 and generate nearly 2 million monthly searches, making them the most commonly researched issue overall.
Airbag replacements, while relatively less expensive at an average of €2,000, carry a high safety impact rating of 25 per cent, reinforcing their critical importance in accident scenarios. Similarly, head gasket repairs and turbocharger replacements, though less costly than battery or engine failures, remain significant due to their frequency and impact on vehicle performance.
The report also introduces a multi-dimensional methodology that goes beyond cost analysis. By incorporating metrics such as online search frequency, safety impact, and implications for resale value, the study provides a more holistic view of how different repair categories affect both the financial and functional aspects of vehicle ownership.
An auto expert at eCarsTrade noted that consumers must increasingly factor repair economics into their purchasing decisions. According to the expert, “Battery and inverter replacements are expenses most traditional car owners never had to consider, but they now sit alongside engine and gearbox repairs as major cost drivers. In some cases, a single failure can exceed the value of the vehicle itself.”
