Peugeot 3008 Hybrid4 300 Mk2

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.

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.

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.

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.

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.

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 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.

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.

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.
