Common Faults & Reliability
These are the most common documented problems for the McLaren 750S, sorted by their typical impact and frequency.
PCC III Accumulator Wear
high severityThe 750S uses ProActive Chassis Control III, an evolution of the 720S system. The hydraulic accumulators remain a consumable wear item with a similar 3-5 year or 15,000-25,000 mile replacement interval. Failure results in a harsh ride and suspension fault warnings.
Software and Infotainment Glitches
medium severityEarly 750S deliveries have been plagued by software issues including infotainment temperature control randomly changing, window position sensor faults, and occasional system reboots. Most have been resolved through OTA updates but verify the latest firmware is installed.
Build Quality and Panel Fit Issues
medium severitySome early 750S cars have experienced build quality issues including inconsistent panel gaps, trim pieces coming loose, and the active aero system failing before delivery. While McLaren has improved QA, inspect carefully.
