Four-wheel-drive front transfer box (PTU)
Severity 2/3 · CostlyPistonHeads explains that the 4WD system's PTU, inherited from the FF, has a reputation for failing: a sealing defect makes hydraulic fluid leak, and the fault shows as “4WD Failure” with the Manettino stuck in Wet mode. The GTC4Lusso uses the same setup; failures are less frequent than before but still occur. A specialist rebuild is quoted at £7,950 (PistonHeads); Not Just a Car reports dealer quotes of $35,000 to $50,000 to replace the unit. It does not concern the GTC4Lusso T's V8, which is rear-wheel drive.
