Bought a 2017ls with 10k 2 years ago. After two visits for grabby brakes they said was normal, the actuator started chirping. FYI, I recognized it immediately since my 2007 needed a new actuator at 40k. Both were covered under extended warrantee and now CPO warranty
3 months later 36k, my actuator just started chirping again. Making an appointment to take it in today.. Still under CPO warrantee
hoping they don't give me a hard time.
