I was able to get Lexus to cover the cost of parts ( I paid labor). I'm not sure exactly which action helped since I voiced complaints on several consumer websites and sent a certified letter to Lexus HQ in California. (I received a phone call from HQ just 2 days after mailing the letter so not sure if letter had even arrived there yet.) After just 2 phone conversation, the agreement was made as above. Within days I had my RX 350 in the nearest dealer and repaired with excellent results.
