Mileage problem-2022 ES 350
I have owned the car for 12+ months and recently my MPG has dropped from 20+ MPG to approximately 14. the 20+ reading were from the computer, the 14 MPG were done manually. I took it in for a 20,000 mile service and the reset the fuel gauge reset but the mileage has dropped back down to 14. Help. Is there an O2 sensor or some other fuel system problem that would have such an effect. Thanks.

How many miles on it (this is important info to include, fyi)?
Brakes, bearings, sensors, etc. A lot to neck down w/more info. Any recent service or mods/parts? You should still be in the full warranty period for non-wear items, correct?

What symptoms would I see if problem is a seized caliper? I know nothing.
Anticipating a problem, I took the car in for a 20000 mile service to local Lexus/Toyota Service Center. Their documentation says the service included an exam of brakes, pads, calipers.all standard fluid levels.Oil/ filter change. It was my first trip in so I have no experience with them.

The way I check for a seized caliper is I’ll take it for a ride on the highway for several miles, taking care to avoid touching the brakes. Obviously, rush hour wouldn’t be the time to do this. After going several miles, pull into the breakdown lane and coast to a stop without using your brakes (uphill grade preferable). Get out and gently touch each rotor with the back of your index finger. If you find three are cool to warm, and the one is red hot, that’s your seized caliper.

That would have been my DDx top thing too, but he’s at 15k miles. Crazy unlikely.
OP: do some in-town, stop-go driving. Park and immediately feel all wheel hubs. A seized brake caliper or bad bearing will be hot/hotter than others. But at 14k miles, very unlikely. Easy test, but either way, dealer issue.
ETA: denzlex’s other methodolgy in post #6 is not bad, but it won’t catch all cases, or bearings. But not unsound, not saying that.
But don’t f’with all that IMO, if you are not a hard corp DIY guy. If you were, you’d have figured this out already. There’s a real problem - check hubs if you feel like it, but toss this on to the dealer’s lap and don’t let them shine you on until they come back with a clear, logical, DOCUMENTED, explanation.
Sometimes, and often, parts that should not fail, fail. Manufacturers we all trust, screw up (Aisin under warranty, has screwed up more of my cars than BMW, Audi, GM, combined - the whole “Toyota/Lexus is infallible” idea was done about 2002). That is what the warranty is for - to catch unexpected early failures. Diagnose on your own, but use that warranty.
