One of Europe's most affordable new electric cars, distributed through the Stellantis dealer network since late 2024. The T03 packs a 37.3 kWh LFP battery, a 70 kW motor, and surprisingly generous equipment (adaptive cruise, panoramic sunroof, six airbags) into a compact city car format. Originally sold in China since 2020 under Leapmotor's own name, European cars were assembled at the Stellantis plant in Tychy, Poland until 30 March 2025, when that line stopped; later cars are imported. Stellantis handles sales, servicing, and parts through its existing European network of over 800 locations.· more· less
OTA updates can fail mid-installation, sometimes causing temporary loss of charging or ADAS functions · more· less
Multiple European owners report OTA update failures where the installation stops partway and displays an error message asking to contact the dealer. In some cases, the car's charging function stopped working after an update, requiring a dealer visit or 12V battery disconnect to reset. Other reported post-update bugs include brake indicator lights not displaying correctly on the dashboard and Auto Hold not engaging properly. Leapmotor's communication about update rollouts has been criticised, with even dealers reportedly unable to get timely answers from the manufacturer after submitting support tickets. Most software issues resolve through a full system reboot (disconnect 12V battery for 10-15 minutes) or a subsequent OTA patch, but the frequency of these problems suggests the software platform is still maturing for the European market.
Charging interruption and premature stop
€0 - 4002 of 6
Car terminates AC charging early, displaying 'Charging complete' before reaching the set limit · more· less
A recurring complaint among T03 owners is that AC charging via wallbox stops prematurely, with the car showing 'Charging complete' even though the set charge limit has not been reached. This appears linked to the battery management system being overly cautious, particularly when cell voltages are slightly unbalanced. Some owners resolved the issue by adjusting wallbox amperage settings (reducing to 10A), while others found that performing three full charge cycles (to 100%) as recommended by Leapmotor for new cars helped the BMS calibrate properly. If the issue persists, a dealer visit for BMS recalibration may be needed. In rare cases, the charging module itself may need replacement, costing approximately €300-400.
Battery cell imbalance and capacity loss
€0 - 3,5003 of 6
Individual cells developing voltage imbalance, causing reduced range and charging anomalies · more· less
A small number of T03 owners have reported significant battery cell imbalance, with voltage differences between cells reaching up to 650 mV (normal is under 20 mV). Symptoms include dramatically reduced range (sometimes half of expected), very slow charging, and battery warning lights. The T03 uses an LFP (lithium iron phosphate) battery, which is inherently more stable than NMC chemistry, making severe cell degradation uncommon. When it does occur, the battery is typically covered under the 8-year / 160,000 km battery warranty. Out-of-warranty replacement would be substantial (estimated around €3,000-3,500 for a 37.3 kWh pack), but given the car's age in Europe (from late 2024), virtually all T03s remain within warranty for this component.
System Fault dashboard error with speed limitation
€0 - 2004 of 6
Dashboard displays 'System Fault, Service required' and limits speed to 25-40 km/h · more· less
Some owners have experienced a sudden 'System Fault, Service required' warning on the dashboard, accompanied by a speed restriction to approximately 25-40 km/h. This has been reported occurring as early as a few hundred kilometres into ownership. In most documented cases, the error cleared after restarting the car, with no recurrence. The fault appears to be triggered by sensor glitches or software communication errors rather than a genuine mechanical problem. If the warning persists after restart, a dealer diagnostic is needed, which is covered under the 3-year vehicle warranty. No reports of costly repairs resulting from this error have surfaced.
HVAC limitations (no heat pump, aircon cold-only mode)
€0 - 1505 of 6
No heat pump fitted, and aircon operates only in cooling mode, making winter demisting difficult · more· less
The T03 does not have a heat pump, relying on a resistive heater for cabin warmth. This significantly impacts winter range, with owners reporting 30% or more reduction in cold weather. Additionally, owners have found that the air conditioning only operates in cooling mode, which complicates winter demisting. The demist function does engage the AC compressor and works effectively, but the system's behaviour can be confusing. Workaround: use the demist button, then adjust temperature and fan speed while remaining in demist mode. Some owners place silica gel bags in the cabin to reduce moisture. This is a design characteristic rather than a defect, but it noticeably affects winter usability and range.
Intrusive ADAS alerts resetting to default
€06 of 6
Driver assistance warnings are aggressive and settings reset to default after each drive cycle · more· less
Leapmotor describes the T03 as having ten ADAS functions, though not all of them are required by EU regulation; adaptive cruise and blind spot detection are among the non-mandated ones. Their calibration has been widely criticised. The lane keeping assist is inconsistent, and when it does engage, the steering correction feels abrupt. The fatigue detection camera can trigger false warnings within minutes of driving. Most frustrating for owners: ADAS settings reset to their default (active) state after each drive cycle, so features like lane departure warning must be manually disabled every time. Leapmotor has acknowledged this as a regulatory compliance issue and stated that improvements are being worked on through OTA updates, but as of mid-2026, the fundamental reset behaviour remains. A workaround exists through the customisable steering wheel button, which can be configured to toggle specific ADAS features.
Simple drivetrain, but software maturity is the main concern
The Leapmotor T03's LFP battery and single-motor drivetrain are mechanically straightforward, and no widespread powertrain failures have been reported. The main ownership challenges are software-related: OTA updates that occasionally fail or introduce new bugs, charging interruptions caused by BMS calibration issues, and ADAS systems that are more annoying than helpful. Most problems are resolved through software patches or dealer resets at no cost. The Stellantis dealer network provides reasonable service access, though dealer familiarity with the Leapmotor platform is still developing. With limited European track record (sales began late 2024), long-term reliability remains unproven.
Service history
Verify all scheduled services completed at a Stellantis-authorised dealer. Required every 20,000 km or 12 months to maintain warranty.
Tires
Check tread depth, age (date codes), and uneven wear. The T03 uses 165/65R15 tires.
Test drive
Drive for at least 20 minutes including varied speeds. Pay attention to any dashboard warnings or ADAS alerts.
Exterior condition
Check for parking damage. As a city car, minor dents and scratches on bumpers are common.
Specific for this vehicle
Test AC charging before purchase
If possible, plug the car into a wallbox or Type 2 charger and verify it charges continuously without premature stops. Check that the displayed charge level matches expectations.
Check battery state of health
Ask the dealer or use the Leapmotor app to verify the battery SoH percentage. On a car this new, it should be above 95%.
Verify software version is current
Check the infotainment system for the latest software version. Ask the dealer to confirm no pending OTA updates are queued.
+ 3 more checksShow less
Test all ADAS functions during the drive
Activate and deactivate lane keeping, adaptive cruise, and collision warning. Confirm they respond correctly and that the steering wheel shortcut button works.
Cold start and system boot
Start the car from fully off (not sleep mode). Watch for any dashboard error messages during the boot sequence, particularly 'System Fault' warnings.
Verify demist and heating function
Test the demist button and heating controls. Confirm warm air is produced and that the windscreen clears within a reasonable time.
