In 2022, a business owner friend took out a 48-month lease on an EV from a brand that had just arrived in Europe. At 14 months, the battery management module failed. Result: 6 weeks off the road, a combustion replacement car, and a claims file that lasted 4 months. The warranty eventually paid out — but no one compensated him for the lost time and stress.
On a long-term lease (48 or 60 months), reliability is not abstract: it is your work tool and your daily mobility.
Are EVs more or less reliable than combustion cars?
Short answer: fewer breakdowns, but more complex ones.
The ADAC (German automobile club) analysed 3.6 million roadside assistance interventions in 2024. For the first time, the EV sample was large enough to be statistically robust:
- EVs: 4.2 breakdowns per 1,000 vehicles
- Combustion cars: 10.2 breakdowns per 1,000 vehicles
In breakdown frequency, EVs are twice as reliable. But when a breakdown occurs on an EV, it most often involves the battery (high or low voltage) or electronics — two components that conventional dealerships still handle imperfectly. Repair times are longer, and replacement cars during the downtime are not always guaranteed.

What does the data show on EV reliability beyond 4 years?
Analysis of available breakdown data shows that the first serious EV immobilisations occur on average around 4 years and 48,000 to 50,000 km. This is not a coincidence: it is when the auxiliary 12V battery (often undersized) starts to tire, and when some first-generation electronic components show their limits.
The good news: on a 48-month lease with 10,000 km/year (40,000 km total), you are below this threshold. On a 48-month lease with 20,000 km/year (80,000 km), you exceed it — and the quality of the manufacturer and their warranty become critical.
Which EVs are most reliable for a long-term lease in Belgium?
Level 1 — Very reliable: Hyundai IONIQ 5/6, Kia EV6
The two 800V platforms from the Hyundai/Kia group represent in 2026 the best long-term reliability record available on the market. The electrical architecture is proven, the battery thermal management is recognised as among the most efficient on the market, and the documented battery degradation on European fleets is around 2 to 3% per year according to Geotab data.
The Hyundai warranty (8 years / 160,000 km at ≥70% capacity) is one of the most extensive on the market. Kia offers 7 years / 150,000 km. The aftersales network in Belgium is dense (60+ approved centres for Hyundai).
Level 1 — Very reliable: Tesla Model 3 and Model Y
Tesla shows a very solid mechanical reliability record, particularly on the drivetrain and battery. The documented battery degradation in the European owner community is among the lowest on the market (< 2% per year under normal conditions).
Point of attention: build quality can be variable (panels, seals), and Tesla's aftersales network in Belgium is limited to 4 centres (Brussels, Ghent, Antwerp, Liège). Waiting times can be long in the event of a claim.
OTA (Over-The-Air) updates regularly fix software problems without going to a workshop — a concrete advantage over the duration.
Level 2 — Reliable: Škoda Enyaq, Volkswagen ID.4
The VW Group's MEB platform has accumulated 5 years of field data since the ID.3 in 2020. The record is broadly positive, with some software problems resolved on first-generation models. The Enyaq benefits from Škoda's reputation for mechanical robustness.
The Volkswagen/Škoda network in Belgium is the densest in the industry (120+ service points). This is a decisive advantage for a long-term lease: you will never have to search far for a workshop capable of intervening.
| Modèle | Prix | Autonomie réelle | Batterie | Recharge DC |
|---|---|---|---|---|
| Hyundai IONIQ 5Recommandé | 41 990 € | 390 km | 77.4 kWh | 233 kW |
| Kia EV6 | 44 990 € | 420 km | 77.4 kWh | 233 kW |
| Škoda Enyaq iV 80 | 43 990 € | 410 km | 82 kWh | 135 kW |
| Volkswagen ID.4 Pro | 45 990 € | 400 km | 77 kWh | 135 kW |
Level 3 — Acceptable with precautions: BMW, Renault
BMW shows satisfactory mechanical reliability on its EVs (i4, iX1, iX3), with an irreproachable aftersales network in Belgium. The point of attention is the out-of-warranty repair cost (premium parts, high labour).
Renault (Mégane E-Tech, Zoé) offers a very dense aftersales network in Belgium, but the early ZOE generations suffered from battery degradation problems. The Mégane E-Tech is more recent and shows a better record.
Level 4 — Insufficient for 48+ months: Chinese brands without local presence
BYD, MG, Xpeng in 2026 do not have an aftersales network in Belgium capable of guaranteeing rapid service on a 4 to 5-year contract. This is not a judgement on the technical quality of the product — it is a logistical reality. A long-term lease requires a local safety net.
EV reliability on a long-term lease is 50% the manufacturer's quality and 50% the density of the aftersales network. An excellent EV whose only service centre is 80 km from your home is a real risk over 4 years.
Which clauses must you absolutely check in a long-term lease contract?
1. The battery degradation clause. Some LLD contracts include a replacement guarantee if the battery falls below a threshold (70% or 75% depending on the manufacturer). Check whether this clause is in your contract or whether it is only the standard manufacturer warranty that applies.
2. The replacement car in the event of immobilisation. An EV with a problem can be off the road for several weeks in the event of a battery issue. Does the contract provide for a replacement vehicle? For how many days? Combustion or electric? This clause is gold on a 48–60 month contract.
3. Return charges related to battery wear. At the end of the contract, some lessors may charge fees if the battery shows degradation deemed "abnormal". Check the thresholds provided and keep charge diagnostic reports if you often fast DC charge.
Le verdict de Christophe F.
For a 48 to 60-month EV lease in Belgium, the two decisive criteria are battery warranty quality and local aftersales network density. Hyundai IONIQ 5 and Kia EV6 dominate the reliability ranking with 7 to 8-year warranties and a solid Belgian network. Škoda Enyaq and VW ID.4 are a notch below technically but compensate with the densest aftersales network on the market. Tesla is mechanically reliable but its network limited to 4 centres in Belgium remains a watch point on a 5-year commitment.
