Hi everyone, apologies in advance if this has been asked many times. Please delete or merge for me.
My first question is, I hear a hissing sound when I have the car turned out for a while. I've read some threads that I might need to reflash the oil something?

My second question is, I purchased the car out of state and they talked me into getting a warranty. I don't have the paperwork delivered to me yet, but is this warranty valid to take to any Lexus dealer? If it's not valid, would anyone know how much it will cost to get this reflash?

Thanks

It sounds like you may be experiencing the fuel pump noise. I just got my RCF and had a buzzing/humming like noise behind the driver's seat. Found there was a TSB for this. L-SB-0031-16

Take that to the dealership. It is not a warranty issue. It is a recall work since early 2015 RCFs had issues with the low pressure rear fuel pumps. Under the recall, the dealership will reflash your ECU and/or replace the fuel pump free of charge.

Thanks you both for the help!
