Bosch Performance Line CX Gen 5 reliability

Gen 5 reads like a fix-list for Gen 4 (silent descending, through-bolt mounts) and after reading every complaint in full, motor-attributable complaints came from only ~40 of 702 members discussing it.

The one real hardware cluster so far is the early-production mount bushing walking out (8 reporters, parts free under warranty); the late-2025 engagement-clunk cluster is the watch item, with one confirmed motor swap. The fleet is young and the 120 Nm update is younger: long-term wear is unwritten.
