I had the dreaded hesitation when getting on it. I took it in for the "whining" fuel pump noise. There was a TSB on this. They flashed the system and eliminated it. It really drives much better. I did have to bend the truth a bit because the dealer had to "hear" the whine.... I offered a ride on a road trip and he could Uber back. He declined and took my word. It's perfect now, awaiting the new pumps they will install with the recall. I hope I don't go backwards...

I mentioned to the Lexus dealer often and they have no fix.....Help what the deal?

Thanks

I couldn't tell you what it is today or on my last trip. I don't think I've ever looked. I only use that bar thing that indicates find a nearby fill up location

There's a fuel pump recall that needs to be reflashed. Also Apexi throttle controller will eliminate that problem.
