EVs have fewer moving parts but new failure modes. Charging system faults, 12V battery drain and software issues are the most reported EV problems. We analyse early reliability data.
This Reliability guide combines structured analysis — verdicts, risk scoring and cost ranges where we have enough data — with real fault cases pulled directly from MyCarFault's reporting database, so the guidance below reflects what owners actually experience rather than manufacturer specifications alone. Background and analysis come first, followed by the linked fault reports and related guides you can jump to directly using the links above.
Electric vehicles have fundamentally fewer mechanical failure points than combustion engine cars — no timing chain, no clutch, no exhaust system, no injectors. But they introduce new reliability categories: high-voltage battery management, charging system hardware, power electronics and software-defined vehicle complexity. This analysis covers emerging reliability patterns from early EV data.
Mechanically simpler, yes. But new failure modes (charging, software, 12V battery) mean total reliability is comparable to a good modern petrol — not dramatically better.
No — for most buyers. Battery degradation is gradual and slow. Replacement in the first 150,000 miles is rare except on specific problematic models.
Early Nissan Leaf (2011-2017) — battery degradation without active thermal management is faster than most EVs. Check real-world range carefully.
