Hello,
Our 2017 RX350, with 73,000 miles, has a loss of power when it shifts to a high gear - automatic transmission. Basically, it bogs and is noisy, like it's not getting enough gas. Slow!!!
There are no codes, but took it into the Lexus dealer to run a computer diagnostic. Their solution was to update the engine and transmission software, which did nothing to fix it. Total was $400, but they graciously comped us an hour of labor, so $300.
I put on new plugs and replaced some of the O2 sensors, also ran engine cleaners to clean the injectors.
My only other thought is the fuel pump or fuel filter. Any thoughts?!?
Thanks,
James

Is the fuel filter original? Have you tested fuel pressure? What do your fuel trims look like?
