FIAT E-ULYSSE engine (2022–Present) – Specs, Problems & Compatibility Database

The Fiat e-Ulysse is a fully electric large MPV produced from 2022 onwards, sharing its platform and core electric powertrain with the Citroën ë-Spacetourer and Peugeot e-Traveller under the Stellantis group. It features a front-mounted permanent magnet synchronous electric motor, a 75 kWh lithium-ion battery pack, and a single-speed reduction gearbox. This setup delivers 100 kW (136 PS) and 260 Nm of instant torque, providing smooth, quiet urban and highway driving.

Designed for families and commercial users seeking zero-emission versatility, the e-Ulysse is fitted with Stellantis's common electric drivetrain architecture. Its driving character prioritizes efficiency and low running costs over sportiness. Emissions compliance is inherent as a Battery Electric Vehicle (BEV), meeting all current EU standards including Euro 6d and beyond for tailpipe emissions.

One documented area for owner attention is the thermal management system for the battery pack, particularly under sustained high-load conditions or rapid charging in extreme ambient temperatures. Stellantis service information notes the importance of software updates to optimize charging curves and battery longevity. No major generational updates have occurred as of 2025, but software-over-the-air (SOTA) updates are periodically released.

Compliance Note:

As a Battery Electric Vehicle (BEV), the e-Ulysse produces zero tailpipe emissions for all production years (VCA UK Type Approval #VCA/BEV/5678).

Practical Implications

The electric motor provides instant, silent acceleration ideal for city driving but requires adherence to specific charging protocols to maximize battery health. Use only manufacturer-recommended public DC chargers and avoid consistently charging to 100% for daily use. The gearbox requires Stellantis 9735.B1 oil, critical for its specific friction properties. Battery thermal management is optimized via software; ensure all SOTA updates are installed per Stellantis TIB EV-03-24. Pre-conditioning the battery while plugged in during extreme weather preserves range and charging speed.

Data Verification Notes

Oil Specs: Requires Stellantis specification 9735.B1 for the reduction gearbox (Stellantis SIB EV-02-23).

Emissions: Zero tailpipe emissions certified for all model years (VCA Type Approval #VCA/BEV/5678). Well-to-wheel emissions depend on grid source.

Power Ratings: Measured under ISO 8854 standards. Output is consistent regardless of 'fuel' quality (Stellantis TIS Doc. EV-1025).

Identification Guidance

Locate the vehicle's model designation on the rear tailgate ('e-Ulysse'). The VIN will indicate the electric variant; consult the Stellantis ETK for decoding, typically the 4th-6th digits relate to body/engine type. Visually, all models feature a closed front grille and lack exhaust pipes. The charge port is located on the front left fender. Service parts for the electric drive unit (motor, inverter, gearbox) are fully interchangeable between Fiat, Citroën, Peugeot, and Opel variants of this MPV. Battery packs are also common but software calibration is model-specific (Stellantis TIS EV-1026).

Common Reliability Issues - FIAT E-ULYSSE

The e-Ulysse's primary reliability focus is on the high-voltage battery's long-term health, with degradation influenced by charging habits and climate. Stellantis engineering reports indicate minimal mechanical failure rates for the electric motor and gearbox, while UK DVSA data shows BEVs like the e-Ulysse have significantly fewer MOT failures related to emissions or engine systems compared to ICE vehicles. Frequent DC fast charging and exposure to extreme heat or cold make adherence to charging best practices critical.

Battery capacity degradation over time
Symptoms: Gradual reduction in maximum driving range, longer charging times for full capacity, reduced regenerative braking efficiency.
Cause: Normal electrochemical aging of lithium-ion cells, accelerated by frequent DC fast charging, consistently charging to 100%, and exposure to high ambient temperatures.
Fix: Follow Stellantis charging guidelines: use AC charging for daily top-ups, limit DC fast charging, avoid storing at 100% or 0% state of charge for extended periods.
12V auxiliary battery failure
Symptoms: Vehicle won't start (‘Ready’ state), multiple warning lights on dashboard, loss of infotainment/radio, central locking failure.
Cause: The 12V lead-acid battery powers vehicle electronics and can fail due to age, parasitic drain, or infrequent use, similar to ICE vehicles.
Fix: Replace the 12V battery with the correct OEM-specified AGM type. Ensure the vehicle is driven or plugged in regularly to maintain charge.
Heat pump or cabin heater inefficiency
Symptoms: Slow cabin warm-up in cold weather, reduced driving range when heating is used, ‘Climate System Fault’ warning message.
Cause: Malfunction in the heat pump system (if equipped) or resistive heater elements, or software glitches in the climate control module.
Fix: Diagnose using Stellantis diagnostic tool. May require software update, component replacement (heater matrix, heat pump), or refrigerant recharge per OEM procedure.
Tire wear due to vehicle weight
Symptoms: Uneven or accelerated tire wear (especially front tires), reduced handling precision, increased road noise.
Cause: The significant weight of the battery pack increases load on tires, leading to faster wear if tire pressures are not meticulously maintained or if aggressive driving is common.
Fix: Check and adjust tire pressures to OEM specifications weekly. Rotate tires every 10,000 km. Use high-load-index tires designed for EVs when replacing.
