Nissan Qashqai e-Power

The e-Power system uses a motor generator unit (MGU) that converts engine power to electricity. On late 2022 and early 2023 production vehicles, the generator has been reported to fail due to insulation breakdown, causing internal short circuits or stator overheating from thermal cycling and vibration. When the generator fails, the car enters a reduced power mode or stops entirely, displaying an e-Power System Fault message. A dedicated Facebook group for this fault has grown rapidly. Replacement parts have had lead times of 10-12 weeks due to limited availability. The MGU replacement costs approximately 1,500-3,000 euro including parts and specialized labour. Nissan dealers have indicated the problem was addressed with production changes for the 2024 facelift. Most failures occur under warranty and are repaired at no cost, but out-of-warranty repairs are expensive.

Nissan recalled 94,404 Qashqai e-Power vehicles manufactured between 2021 and 2024 under KBA reference 14969R (manufacturer code R24C8). A software calibration error in the battery management system (BMS) causes the calculated battery state of charge to fluctuate rapidly. This triggers limp-home mode while driving and can prevent the vehicle from restarting after being switched off. The fix is a free BMS software update at any Nissan dealer. If the recall has not been completed and a fault occurs, the car may need towing to a dealer, which could cost 100-200 euro out of pocket. This is a widespread issue affecting a large proportion of e-Power vehicles, making it essential to verify the recall status before purchase.

A well-documented issue across the J12 Qashqai range, particularly affecting the e-Power. The car's connected services (NissanConnect), alarm system, and various electronic modules draw continuous power from the 12V battery. Unlike conventional cars, the e-Power has no alternator, so the 12V battery is only charged when the car is running. Owners report the battery going flat within 7-14 days of inactivity, requiring jump starts or roadside assistance. The 12V battery costs approximately 150-250 euro to replace. Some early models had defective batteries replaced under warranty. A trickle charger is recommended if the car regularly sits for more than a week. The system will not charge the 12V battery from the traction battery when the car is off, unlike some full hybrids.

A smaller number of e-Power owners have experienced voltage fluctuations from the 2.1 kWh lithium-ion traction battery. This manifests as an e-Power System Fault warning that cannot be cleared with a simple restart. In some cases, Nissan has had to replace the entire battery pack. The traction battery is covered under Nissan's battery warranty (8 years / 160,000 km in most European markets), so if the failure occurs within warranty it is repaired at no cost. Out of warranty, a replacement traction battery for the e-Power system costs approximately 3,000-6,000 euro depending on whether new or refurbished. This is a rare issue but represents the highest potential single repair cost on the e-Power.

A widely reported problem specific to the e-Power variant. The front brake pad shims (thin metal anti-rattle clips) deform under heat, causing the pad to wobble and produce a persistent high-pitched squeal. Some owners report the squealing is noticeable at low speeds and when turning. Nissan acknowledged the issue and redesigned the shim part (changed part number), but revised parts were on backorder for months as they were shipped from Japan. One dealer reported having fixed over 100 vehicles for this issue. The repair is typically covered under warranty and involves replacing the brake shims, and if the deformed shims have scored the brake discs, those are replaced too. Out of warranty, the shim replacement costs approximately 100-150 euro, or 200-300 euro if discs are also scored and need replacement.

The Qashqai e-Power uses Nissan's innovative variable-compression turbo engine (KR15DDT), which has a complex multi-link system to vary the compression ratio. This system introduces additional bearings (main, A-link, C-link, and L-link) beyond a conventional engine. A massive recall was issued for the 2.0L VC-Turbo (KR20DDET) in the US for bearing failures, and the 1.5L three-cylinder variant shares the same fundamental design. Nissan estimates approximately 1.2% of vehicles may actually have the defect. In Europe, a separate recall addresses the BMS software rather than the engine bearings directly, suggesting the 1.5L variant may be less affected. However, the engine's inherent complexity remains a long-term concern. Symptoms include abnormal engine noise, rough running, and metallic debris in the oil pan. If bearing failure occurs, engine replacement costs 4,000-7,000 euro. Because the engine only runs as a generator at optimised speeds, it experiences less stress than in a conventional drivetrain, which may reduce the risk.

The J12 Qashqai's NissanConnect infotainment system is the source of the most common non-drivetrain complaints. Owners report the screen failing to boot, losing GPS location, failing to recognize USB connections, and the play button becoming unresponsive. In most cases, a software update at the dealer resolves the issues at no cost. In rare cases where the head unit hardware has failed, replacement costs approximately 300-400 euro. These issues affect all J12 Qashqai variants, not only the e-Power. Later software versions have improved stability significantly.
