🔧 Mechanic's Notes

A/C complaints are the 9th-gen signature — compressor clutch and condenser are the first things to check when it blows warm.
Front motor mounts wear early and read as 'clunk on shift' — cheap fix, often misdiagnosed as transmission trouble.
2014–15 CVT cars: fluid is Honda HCF-2 only, and 'lifetime fluid' is marketing — service it by 100k km.

Field patterns from a working mechanic — diagnose your own car before buying parts.
