The second-generation C3 Aircross is Citroën's affordable compact SUV, available with up to seven seats on Stellantis's Smart Car platform. The Hybrid 136 pairs the new chain-driven 1.2 PureTech Gen3 engine with a 48V mild-hybrid system and the e-DCS6 dual-clutch automatic from Punch Powertrain, allowing electric-only driving for short stretches in urban traffic. It eliminates the infamous wet timing belt of its predecessor, but introduces a new gearbox that has attracted significant early complaints across the Stellantis range. This report covers the Hybrid 136, which Citroën introduced in October 2024. The 145 hp Hybrid 145 arrived alongside it from April 2025 and is a different system output; some of the recall windows below run past that date, because they cover the shared platform rather than this powertrain alone.· more· less

Transmission hesitates, jerks, or enters protection mode, especially in stop-and-go traffic · more· less
The e-DCS6 dual-clutch gearbox, developed jointly with Punch Powertrain, is the most widely reported issue on Stellantis 48V hybrid models from 2024. Owners describe severe jerking when the system transitions between electric and petrol power, hesitation from standstill, and sudden protection-mode lockups with 'gearbox failure' warnings. Error codes P1749 and P28EA are commonly logged. Some failures have occurred as early as 2,000 km, with oil analysis showing dark, burnt fluid and clutch wear reaching 40-50% by 10,000-20,000 km. Stellantis has released multiple software updates for the TCU (transmission control unit) that improve shifting behavior, and intervention rates have reportedly dropped from around 32% on MY2024 to approximately 14% on MY2026 cars with software version 2.1.x. If a software update resolves the issue, cost is minimal (€0-80). If the mechatronic module fails, replacement costs €950-1,450. A full dual-clutch replacement runs €1,700-2,900 depending on dealer vs independent workshop. In 2025 Stellantis bought out Punch Powertrain's minority stake in the eDCT joint venture that builds this gearbox, taking full ownership of the venture; the announcement does not present that step as a quality measure.
Camshaft sprocket bolt loosening (engines built before 18 Feb 2024)
up to €1,5002 of 7
Camshaft sprocket bolts on Gen3 engines produced before 18 February 2024 can work loose, causing timing slippage · more· less
The first batch of Gen3 PureTech chain-driven engines manufactured between 2023 and February 17, 2024 have a documented camshaft sprocket bolt defect. The incorrectly positioned screw can loosen over time, allowing the camshaft phaser to shift and causing timing slippage. Symptoms include power loss, engine warning lights, misfiring, and abnormal noises. Fault codes P0012, P0015, P0016, and P0017 are diagnostic indicators. Stellantis implemented two corrections: a camshaft phaser upgrade on January 31, 2024, and a new pinion screw on February 18, 2024. Vehicles built after mid-February 2024 are unaffected. This is handled as a warranty repair under Stellantis technical notes rather than as a safety recall, and the cut-off is the engine's own production date, not the vehicle build date on the door jamb. Affected cars have the camshaft screws and sprockets replaced under warranty; out of warranty the same work costs approximately €800-1,500. Before purchasing, ask a Citroën dealer to check the engine number against the campaign and whether the work has been carried out.
GPF/BSG clearance fire risk (48V hybrid specific)
up to €5003 of 7
Insufficient gap between the particulate filter pipe and the 48V starter-generator cap can cause overheating · more· less
On some 48V mild-hybrid models, the gasoline particulate filter (GPF) pipe is positioned too close to the 48V belt starter generator (BSG) protection cap. In wet conditions, water can infiltrate the gap and create an electrical arc, potentially leading to overheating or fire. This affects vehicles assembled between 2023 and 2025 across multiple Stellantis brands. Approximately 700,000 vehicles globally are covered by this recall. The fix involves replacing the BSG protection cap and repositioning or replacing the GPF pipe. This is performed free of charge under the recall campaign. Verify with a Citroën dealer whether your vehicle is affected.
Infotainment system freezing and reboots
up to €1,2004 of 7
10.25-inch touchscreen freezes during navigation or Apple CarPlay, reboots take 25-40 seconds · more· less
The infotainment system accounts for approximately 26% of reported problems on the new C3 Aircross. Common issues include screen freezes during navigation or smartphone mirroring, Apple CarPlay disconnections via USB-C cable, and unexpected system reboots that take 25-40 seconds to complete. These are primarily software-related and most resolve with dealer software updates at no cost. In rare cases where the display unit itself fails, replacement costs €500-1,200 for the module. A weak or aging 12V battery can also trigger infotainment glitches, so battery condition should always be checked first.
High-pressure fuel line loose nuts (fire risk)
up to €2005 of 7
Insufficient tightening of fuel line nuts between pump and rail can cause leaks and fire risk · more· less
Vehicles manufactured between March 15, 2024 and April 23, 2025 are affected by a recall (code GJ6) for loose nuts on the high-pressure fuel line connecting the pump to the injection rail. This can cause a fuel leak and potential fire. Approximately 162,880 vehicles globally are affected across multiple Stellantis models. The fix is straightforward and performed free at the dealer. Always verify with the VIN whether this recall applies and has been completed.
ADAS false interventions
up to €3006 of 7
Automatic emergency braking and lane-keeping assist trigger false alarms under certain conditions · more· less
About 18% of early-owner complaints relate to overly sensitive driver assistance systems. Automatic emergency braking has been reported to trigger when passing parked roadside vehicles, and the lane-keeping assist can pull the steering on roads with worn markings. The drowsiness detection also intervenes too frequently on some cars. These issues are addressed through software calibration updates at the dealer. Stellantis released an ECU software update for the ADAS sensors, a broader recall of over 113,000 cars addressed faulty BCM software that could display incorrect speed limits on the C3, and the corresponding C3 Aircross action covers front camera and CVM calibration. Cost is typically zero under warranty or recall.
Build quality rattles and squeaks
up to €3007 of 7
Dashboard squeaks over uneven surfaces affect roughly 14% of MY2024 cars · more· less
As a budget-focused vehicle, the C3 Aircross Mk2 uses cost-conscious interior materials. About 14% of MY2024 models have dashboard squeaks over rough surfaces, door panel misalignments, and wind noise above 110 km/h. These are not safety concerns but can be irritating. Dealers can address squeaks by adding felt pads or adjusting trim clips, typically at no cost under warranty. MY2025 and later production has shown improvement.
Improved engine, but new gearbox needs maturing
The switch to a chain-driven Gen3 PureTech engine eliminates the infamous wet timing belt that plagued the Mk1. This is a significant improvement. However, the e-DCS6 dual-clutch gearbox from Punch Powertrain is still being refined, with early production models showing high intervention rates for jerking, clutch wear, and protection-mode lockups. Stellantis has responded with multiple software updates, and in 2025 it bought out Punch Powertrain's minority stake in their eDCT joint venture. Later production cars (MY2025+) with updated software show markedly lower fault rates. The engine itself appears solid once past the early camshaft bolt issue, corrected in engine production from 18 February 2024. Multiple recalls affect this model, so thorough VIN checking is essential.
Service history
Complete Citroën dealer records are important for maintaining the We Care extended warranty. Verify all services were done on schedule.
Cold start
Start the engine completely cold. Listen for unusual rattling or misfiring in the first 30 seconds. The hybrid system should engage smoothly.
Test drive at least 30 minutes
Drive in varied conditions including stop-and-go traffic and open road. The gearbox issues are most apparent in urban driving with frequent electric/petrol transitions.
Check tire condition
Inspect tread depth, age (date codes), and wear patterns. Uneven wear may indicate alignment or suspension issues.
Specific for this vehicle
Test gearbox in stop-and-go traffic
Drive for at least 15 minutes in slow urban traffic with frequent stops and starts. Feel for jerking, hesitation from standstill, or any 'gearbox failure' messages on the dashboard.
Verify production date and recall status
The camshaft bolt correction is keyed to the engine's production date, not the vehicle build date on the door jamb, so ask a dealer to check the engine number rather than reading the plate. Contact Citroën with the VIN to confirm the fuel line, GPF/BSG, steering harness and brake actions are completed.
Check gearbox software version
Ask the dealer to confirm the current TCU software version. Version 2.1.x (available from MY2026) significantly reduces transmission issues. Earlier versions may still exhibit jerking.
+ 3 more checksShow less
Monitor infotainment during the test drive
Test all touchscreen functions including Apple CarPlay and navigation. Watch for screen freezes, reboots, or Bluetooth disconnections during the drive.
Check 12V battery voltage
A weak 12V battery can cause cascading electrical faults in the hybrid system. Voltage should be above 12.4V with the engine off. Ask the dealer when the battery was last tested.
Inspect under the bonnet for GPF/BSG recall fix
If the car has the 48V hybrid system, check whether the BSG protection cap has been replaced as part of the GPF clearance recall. The updated cap is visually distinguishable.

Brake pedal bracket pin (UK R/2025/514, Safety Gate SR/04252/25) — built 10 June to 2 November 2025Verify if applicable
This is a new model with an unusually high number of early actions. Contact Citroën with the VIN to verify every one has been completed before purchase. The fuel line, GPF/BSG and steering harness actions are safety-critical, and the two brake actions carry different production windows, so a car can fall inside one and outside the other. Both brake actions were published for right-hand-drive markets. The camshaft sprocket bolt correction is often listed here as a recall; it is a warranty repair keyed to engine production up to 17 February 2024. A body control module software action is also often attributed to this car, but the regulator register maps that software work (GR2) to the C3, while the C3 Aircross action GU7 covers front camera and CVM calibration.
