500h disappointing MPG
#16
i totally agree i had the nx hybrid and was at 27.5 which was a little low to marketing but only by .5 mpg. I am getting 368 to a full tank its saying 24/25 mpg on the gauge yet the calculation to the 17.2 gallon tank is more like 20.4 im calling immediately to thw corporate office

Same issues here
At 1800 miles, I am having the same issues. My mpg isn’t as bad, but at 24 mpg it is still lower than what it should be. I am also having an issue with not being able to put more than 13 gallons of gas in the tank when the gauges say it’s empty. I took the car to the dealer and the technician said this is an issue known to Lexus and they are working on a solution. He said that gas tanks have been sent in to test the capacity but he has not heard the results. They are also looking at the sensors and the possibility of a software update. He said that because the issue involves the fuel system, all solutions need to be reviewed by the EPA. So it is unlikely that any solution (even a simple software update) would be available to the dealers before the end of the summer. He said it is not recommended to drive the car much past empty since it is not known if that would trip another sensor and cause other issues. This is beyond frustrating since I drive a lot and have to stop often to fill up. I didn’t think I would have these issues with a Lexus.

Same experience here. MPG is super disappointing a feels unethical by Lexus. I've had two hybrids and a full electric vehicle and know all about driving to maximize mileage. This vehicle is terrible for that.
1) no matter what I do I can't get past 24; on average I'm in the 21 - 23
2) the reported MPG (stated above) is not even correct - I tested it with two tanks and just did the math and the car is overstating the MPG by 0.5 - 1.0 MPG
3) I ran the tank to zero miles remaining and got 14 gallons in it. According to Lexus service, there is a 2.6 gallon reserve. But they also say the tank is supposed to be 17.2 gallons. So there is still almost a gallon missing from all this math ... WTF???!!
I like how the car drives etc but i would not have bought this were it not for the misleading mileage data. Shame on Lexus. Probably the last time I will buy something from them.

Consistently Poor mpg on TX 500h
We’ve had our TX 500h for 6 weeks and we have 1800 miles on it. With a mixture of interstate and city driving, we’ve been unable to get more than 300 miles on 15 gallons(less than 20 mpg). We’ve kept it in eco mode and are not aggressive drivers. We’re very disappointed. This is approximately the same mpg we got with city driving in the non-hybrid 2018 V6 Honda Odyssey we replaced. Yesterday, the TX had to be towed to our dealer due to an inability to shift out of park when attempting to leave the grocery parking lot and numerous dash warnings including:
hybrid system malfunction-see ownder’s manual
shift system malfunction-see owner’s manual
system malfunction- visit your dealer
drive-start control malfunction-visit your dealer
12-volt battery charging system malfunction-see owner’s manual
I hope that we don’t have a lemon. This is likely the 1st and last time we buy a Lexus.

yes and no. what makes you think toyota/lexus put out an unreliable vehicle for the first generation? new cars are sold with warranties for a reason. I am not sure why you are such a glass half empty person.

I am not saying its unreliable. I am not sure what make you saying I am a glass half empty person. All manufacturers' get feedback from 1st generation owners, make improvements, and come up with 2nd generation. And same for 3rd generation and on and on. All manufacturer put warranties so that customers can buy with confidence. And currently Toyota and other Japanese car manufacturers just got caught cheating on data, including Lexus RX and Toyota Corolla, so it is reasonable to say its reputation are cracking rapidly.
