Welcome to the forum Angelo!Hello everyone, how are you, my name is Angelo Semorile and I am writing to you from Lima-Peru.
I probably have the 1st LC here and bought the gasoline version with a NON-hybrid 2.4 turbo engine.
I have the same rattling sound basically when cold, between approximately 1500 and 2500rpm, so I can assure you that it is not a problem with the hybrid.
I have filed a complaint with my dealership and they tell me that they do hear the sound but that it is NOTHING, obviously I am not satisfied and I have requested an official communication and a report.
I will let you know that from what I have read, no one from TOYOTA has yet stated what the problem really is (let's rule out the hybrid).
greetings
