Renault Zoe
Small family car · 3 electrical system faults
5.0 out of 10electrical system score
- High severityFrequency: CommonElectrical systemCaméléon integrated charger failure and charging cut-outsThe Zoe's Caméléon integrated charger is the component with the most reported faults in the reliability studies consulted: it can stop charging completely (power module, mainly between 5 and 7 years or before 100,000 km) or refuse to charge because of its sensitivity to faulty earth connections.Repair: €3,000–€4,250
- Critical severityFrequency: OccasionalElectrical systemElectric motor and reduction gear failureSeveral owners document failures of the electric motor or the reduction gear - bearings, seals or the reduction gear itself - between 59,000 and 152,000 km, with repairs of up to €6,000 and at least one case where Renault did not cover the fault because, according to the manufacturer itself, it was a 'known design defect'.Repair: €6,000Appears at around 59,000 km
- Critical severityFrequency: RareElectrical systemRisk of an internal short circuit in the traction battery (2020, 2022 and 2024 campaigns)Renault has recalled the Zoe three times (2020, 2022 and 2024) over manufacturing defects in very specific batches of the traction battery that can cause an internal short circuit and a fire risk; the known numbers are minimal compared with the more than 420,000 Zoe built.

- Critical severityFrequency: OccasionalElectrical systemFaulty wiring under the floor: loss of lights, power steering and brake servo (Tonale 2022-2023)Yes: a Safety Gate alert from March 2023 (campaign 6574) covers 607 Tonales built between 15 September 2022 and 13 February 2023, whose wiring under the floor can knock out the lights, hazard lights, power steering and brake servo.
- Critical severityFrequency: OccasionalElectrical systemPoorly tightened nuts on the 12 V charging cable and high-voltage connectors (plug-in hybrid Tonale)Yes: campaign 6683 (Safety Gate alert 42/2023) covers Tonales built from 15 September 2022 to 26 August 2023 because nuts on the 12 V charging cable, the earth cables and the high-voltage connectors are missing or under-tightened, with a risk of overheating and fire. The DVSA limits it to plug-in hybrids.
- Critical severityFrequency: OccasionalElectrical systemFaulty 48 V battery valve: risk of loss of function and overheating (mild-hybrid Tonale)Yes: Safety Gate alert 28/2023 (campaigns 6623 and 6624) covers mild-hybrid Tonales built between 11 November 2022 and 6 February 2023: the pressure build-up valve in the 48 V battery may be faulty and, if water gets in, cause loss of function and overheating. It also includes the Fiat 500X and the Fiat Tipo.
- Medium severityFrequency: OccasionalElectrical system12 V battery drained by standby drain (Tonale)It is one of the most cited complaints in Tonale owner testimonials: 6 of the 29 collected by fiches-auto mention the 12 V battery, with one case of 15 interventions in two years. The cause that source points to is usually a parasitic drain from modules that don't go to sleep, rather than the battery itself.

BMW i4 G26
Saloon · 4 electrical system faults
5.2 out of 10electrical system score
- Critical severityFrequency: OccasionalElectrical systemHigh-voltage battery protection pads may be missing on 2021 i4 modelsYes: in January 2022 Safety Gate reported that i4 cars built between 15 September and 30 November 2021 could be missing the protective pads for the high-voltage battery. In a severe side impact the battery could be damaged and cause a short circuit, with a higher risk of fire.
- Critical severityFrequency: OccasionalElectrical systemManufacturing defect in high-voltage battery cells (fire risk)Yes: in 2022 BMW recalled i4, iX and i7 models built between July 2021 and July 2022 because of a manufacturing defect that can cause high-voltage battery failures and a risk of fire. A supplier may have damaged a cathode plate in the cells; the affected modules are being replaced.

5.2 out of 10electrical system score
- Critical severityFrequency: OccasionalElectrical systemPlug-in hybrid inverter software fault: combustion engine may not restartOn plug-in hybrid Evoques, an inverter software fault (EPICB) can stop the combustion engine restarting once the high-voltage battery runs down in electric mode, and the car loses traction without warning. Recall D035 is corrected with a software update.
- Critical severityFrequency: OccasionalElectrical systemFire risk in the high-voltage traction battery of plug-in hybridsIn 2026 the British DVSA published a recall because the high-voltage traction battery of some plug-in hybrid Evoques has overheated, with smoke or fire under the rear of the car. The root cause is not yet known; batteries are being inspected and those at risk replaced.
- High severityFrequency: OccasionalElectrical system48 V electrical overload can damage the mild hybrid MOSFET transistorIn 2020 Land Rover recalled Evoques with a 48 V electrical system because an overload can damage the system's MOSFET transistor. The DVSA says it is corrected with a software update; fiches-auto links the fault to a risk of fire from the DC-DC converter.

- Critical severityFrequency: OccasionalElectrical systemStarter motor corrosion from water ingress (fire risk)Yes: in September 2025 BMW recalled 4 Series cars (G22, G23 and G26 among them) because the starter motor can let in water and corrode; in the worst case, a short circuit overheats the part and can cause a fire. The press reports that replacing the starter is free of charge.
- Critical severityFrequency: OccasionalElectrical systemWear of the RSW22 starter motor relay contact (fire risk)Yes: in 2026 BMW extended the starter motor recall because, in the RSW22 model with a water-resistant reinforced relay, the magnetic contact wears and builds up deposits, which can cause false starts or a short circuit with fire risk. It affects the 4 Series from 2020, and the starter is replaced with one from a different supplier.
- Medium severityFrequency: OccasionalElectrical system48 V battery cables of the belt-driven starter generator not securely fastenedIn January 2021 BMW carried out a recall in the United Kingdom on several models, including the 4 Series built between August and September 2020, because the battery cables of the 48 V belt-driven starter generator might not be securely fastened. The remedy is to inspect the bolted connection and retighten it if necessary.
