The S63 powers the M5, M6, X5M, and X6M — and carries the same rod bearing risk across all of them. One engine hub for the complete failure picture.
"The F10 M5 is a 560 HP bargain that becomes a $25,000+ money pit without preventive rod bearing replacement. Do the bearings at 60k miles or do not buy."

VANOS solenoids begin failing. Battery parasitic drain issues. Suspension bushings worn.
ROD BEARING CRITICAL WINDOW. Turbo oil line leaks begin. Fuel injectors start leaking. This is where preventive bearings must be done.
Full turbocharger failures begin. DCT overheating on tuned cars. Valve stem seal issues. Oil consumption increases.
Rod bearing catastrophic failure risk peaks. Multiple simultaneous oil leaks. Steering rack replacement. Car becomes financially total-loss risk.
