The fastest and most complex variant of the second-generation 3008, combining a 200 hp 1.6 PureTech petrol engine with a front electric motor and a rear electric motor for all-wheel drive and a combined 300 hp. It shares the core PHEV powertrain with the Hybrid 225 but adds the rear electric axle for e-AWD. The 1.6 EP6 engine uses a timing chain rather than the wet timing belt found in the smaller 1.2 PureTech, which avoids that particular weak point. Sold exclusively as the GT trim level with 19-inch wheels and extensive standard equipment.
Chain-driven EP6, avoids wet belt issue
e-AWD with 300 hp combined output
Rear motor adds complexity over 225
HV battery out-of-warranty risk costly
Buy if: You charge regularly at home, want AWD capability and strong performance from a PHEV SUV, and can confirm all recalls and software updates have been completed.
Avoid if: You rarely charge (the petrol engine carries 350+ kg of dead hybrid weight), want simple ownership, or are uncomfortable with PHEV complexity and recall history.
Expected Annual Maintenance Costs
Common Problems
13.2 kWh pack loses usable capacity over time, out-of-warranty replacement is expensive · more· less
The lithium-ion battery is warranted for 8 years / 160,000 km to 70% of original capacity. Some owners report noticeable range reduction (from the official 59 km WLTP to 25-35 km in practice) within the first few years, though most cases stay within warranty limits. After the 8-year window, a full pack replacement at a Stellantis dealer runs around €8,000-9,000, while individual module repair or refurbishment at a specialist costs €2,500-4,500. Capacity-related warning messages are often resolved with a software update (€90-200) rather than hardware. Leaving the battery at 100% or 0% for extended periods accelerates degradation. Always check battery state-of-health (SoH) via dealer diagnostics before purchase.
Intermittent hybrid system fault, charging fault or limp-mode warnings, usually software-related · more· less
One of the most frequently reported issues on 3008 Hybrid forums. Owners report messages such as 'hybrid system fault', 'electric traction system fault', 'charging fault', and occasional limp-mode events. In the majority of cases these are traced to software or control-module communication faults between the BSI, battery management unit and hybrid controller rather than hardware failure. A dealer diagnostic and software reprogramme resolves most cases (€90-250). Multiple software campaigns have been issued by Stellantis, including a 2023 update that significantly improved stability. One owner reported 13 software updates were needed before the system functioned properly. Persistent faults after a reset can indicate failing sensors or the hybrid control unit itself (€400-600). The Hybrid4 300 has additional wiring and controllers for the rear motor, providing more potential points of failure than the FWD Hybrid 225.
Rear motor disengages with fault messages, reducer bearings can wear and become noisy · more· less
Specific to the Hybrid4 300 (not the FWD Hybrid 225). The rear electric axle contains a permanent magnet synchronous motor and a reduction gear. Forum reports document cases where the rear motor stops engaging, with multiple fault codes appearing on the dashboard. One documented case at 17,800 km required rear axle replacement under warranty. The reducer bearings can develop noise if the oil is not changed periodically, though Peugeot does not specify a fixed interval for this service. Specialists recommend reducer oil changes every 40,000-60,000 km. If the reducer fails, replacement including labor runs €1,500-2,500 at a specialist. Full rear motor assembly replacement can reach €3,000-4,000. Peugeot issued a recall in 2021 regarding non-compliant electric motors on certain hybrid 3008 models.
EP6 timing chain stretches prematurely, aggravated by frequent hybrid start-stop cycles · more· less
The 1.6 PureTech 200 (EP6FADTXHPP) uses a timing chain that can stretch, typically between 80,000-120,000 km. The hybrid system adds extra load through frequent engine restarts during mode transitions (EV to petrol and back), which accelerates tensioner wear. The plastic chain guide is thin and wears quickly, causing chain rattle on cold starts. If ignored, the chain can skip teeth and cause catastrophic valve-piston contact. Early warning: metallic rattling for a few seconds after cold start. Replacement of chain, tensioner, guides and VVT gears costs €1,200-1,800 at a specialist or €2,000-3,000 at a Peugeot dealer. Peugeot revised the tensioner on later production cars. Regular oil changes every 10,000 km with the correct 0W-30 or 5W-30 specification are essential.
NAC/NACe touchscreen freezes, goes black or reboots spontaneously · more· less
The NAC/NACe infotainment system used across Stellantis PSA models is prone to screen blackouts, freezing and spontaneous reboots. Bluetooth pairing drops, the navigation can crash mid-route, and the climate controls become inaccessible because they are routed through the touchscreen. A long-press reset (hold the phone button for 8-10 seconds) usually restores function. A full 12V battery discharge can trigger a permanent black screen that needs a dealer BSI recalibration. Software updates from Stellantis have improved stability on 2021+ models. A diagnostic scan and software update typically costs €60-150 at an independent garage, rising to €250-500 if the control unit needs replacement.
AGM 12V battery wears out faster than in non-hybrid models, typically after 3-4 years · more· less
PHEVs rely on the small 12V AGM battery to boot the hybrid control systems before the high-voltage pack comes online. On the 3008 Hybrid4, owners report 12V battery failure after 3-4 years, sooner if the car sits unused for extended periods with a low state of charge on the HV pack. Symptoms include failure to start the hybrid system, multiple unrelated warning lights on first wake, and intermittent infotainment faults. A genuine AGM replacement costs €150-250 including fitting. Registration of the new battery to the BSI (mandatory on this generation) adds €50-100 at a dealer or independent with diagnostic equipment.
Stellantis recall MA5 addresses water drainage from the HV battery support frame · more· less
Stellantis issued recall MA5 in 2023 for water accumulation in the HV battery support frame. On cars built between March 2019 and December 2022, inadequate drainage can allow water to pool around the battery housing, leading to corrosion and potentially compromising the battery cover. The recall fix involves drilling drainage holes in the support frame and verifying the protective wax coating. Some early models were also missing the protective wax on the battery reinforcing plate (separate recall). Both are free repairs, but unaddressed cars carry increased risk. Budget €200-400 for battery frame inspection and sealant work if the recall was not performed.
Water drips from headliner near rearview mirror on cars with panoramic sunroof · more· less
A well-documented issue across the 3008 Mk2 range, not limited to the Hybrid4. Water enters through gaps between the side rails and front rail of the panoramic roof frame, then pools and drips from the rearview mirror housing during braking or cornering. Peugeot issued TSB C2AW011LQ0 addressing the issue, involving resealing and possibly replacing drainage pipes. A dealer repair under the TSB runs €200-500. If drainage pipes are blocked or headliner is stained, costs can reach €600-800. Only affects cars equipped with the panoramic sunroof option (standard on GT trim, which is the only trim level for the Hybrid4 300). A DIY seal with butyl mastic tape can fix minor cases for under €20.
1.6 PureTech can consume oil between services, worst cases indicate piston ring wear · more· less
The EP6 engine family has a documented tendency for oil consumption, especially when thin 0W-30 oil is used. Most cases are within Peugeot's acceptable limit (0.5L per 1,000 km), but some owners report needing top-ups between services. More severe consumption points to piston ring wear, which can require engine work costing €1,500-2,500. Regular oil level checks are important. Using the correct oil specification and changing at 10,000 km intervals helps prevent the issue. The Hybrid4's frequent start-stop cycles can contribute to carbon buildup around piston rings.
More complex than the Hybrid 225 due to rear electric axle
The Hybrid4 300 shares its core strengths and weaknesses with the Hybrid 225 but adds the rear electric motor and reducer, introducing additional failure modes unique to the AWD variant. The EP6 timing chain is a known concern but avoids the wet belt problem of smaller PureTech engines. Hybrid system software faults are widely reported but mostly resolved through dealer updates. The battery-related recalls (MA5 for corrosion, BMS software for fire risk, and the 2023 charging cable recall) are critical safety items. Verify all recall work, the current software version, and battery state-of-health before purchase.
