Lancia Ypsilon Hybrid Mk4

The e-DCS6, developed jointly with Punch Powertrain, is a brand-new transmission designed specifically for Stellantis' 48V mild hybrid system. Owner reports from Peugeot, Opel and other Stellantis models using this gearbox describe severe mechanical knocking during transitions between the electric motor and petrol engine, particularly in stop-and-go traffic. Diagnostic codes P1749 00 and P28EA 62 have been logged on affected vehicles. Some cars with as few as 10,000-15,000 km have experienced broken eccentric parts, inability to engage Drive or Reverse, and complete electrical power loss. Stellantis acquired full ownership of Punch Powertrain in early 2025 partly to address quality control. Warranty claims for gearbox replacements have been reported at multiple dealers. Software updates may resolve milder shifting complaints, but mechanical failures require gearbox repair or replacement.

Stellantis recalled approximately 238,000 vehicles produced between 2023 and 2025, including the Lancia Ypsilon, due to insufficient tightening of nuts on the pipe connecting the high-pressure fuel pump to the injection rail. This can result in fuel leaking onto hot engine components with a risk of fire. In France alone, 11 cases of vehicles catching fire were reported before the recall was issued. The repair is a free 30-minute dealer intervention. This is a safety-critical recall and must be verified as completed before purchase.

In March 2026, Stellantis launched a Europe-wide recall affecting over 211,000 vehicles with the 1.2 PureTech MHEV 48V engine, produced between 2023 and 2026. The problem involves insufficient clearance between the gasoline particulate filter duct and the protective cap of the 48V Belt Starter Generator. Under wet conditions, friction between these components can allow water ingress that creates an electrical arc, leading to overheating. Stellantis documented 36 incidents, 12 of which resulted in engine compartment fires, though no injuries were reported. The fix involves replacing the protective cap with an improved version and adjusting the component gap, taking approximately 30 minutes at no cost.

The first batches of the 1.2 PureTech Gen3 engine, manufactured between 2023 and February 17, 2024, had a defect where a camshaft sprocket screw was incorrectly positioned. This can cause power loss, warning lights, timing system shifts, abnormal noises, misfiring, and premature wear. Stellantis implemented two fixes: a camshaft phaser upgrade on January 31, 2024, and a new pinion screw on February 18, 2024. Vehicles produced after this date are unaffected. Cars built before the fix that have not had the recall completed could face significant engine damage if the timing slips. Verify production date and recall completion status.

The 48V BSG integrates starter motor and generator functions. Failures can occur due to internal short circuits, overheating of power transistors, or electronic control faults. When the BSG fails, the engine may stall unexpectedly while driving, causing loss of power steering and brake assistance. Replacement costs typically exceed €1,000 including labor. This is a relatively new component with limited long-term data. Stellantis' experience with 48V systems across its broader range (including the eTorque system on Ram trucks, which saw significant warranty claims) suggests this component warrants monitoring.

A recall affecting approximately 9,500 Stellantis CMP-platform vehicles manufactured between April and May 2024 addressed a potential crack inside the electric power steering motor. This can cause steering to become heavy or, in the worst case, lock up entirely during driving. While this recall targeted a narrow production window, the EPS system on the CMP platform has been flagged as a monitoring point. Verify recall status by production date. If the steering feels unusually heavy at any point during a test drive, do not purchase the vehicle.
