Sudden Mileage Decrease
I have a 2013 ES 300h. I bought it January 2013 and already have more than 72,500 miles on it. Yes, I know, I drive a lot, which is why I bought this particular car. I wanted comfort and good gas mileage. Up until Feb of this year I was consistently getting between 36-38 mpg. In stop and go traffic on the LA freeways I would get 41-43. Suddenly the mileage started going down and now it's at 32-34 mpg. After a fill-up, I'll get the 36 mpg until I hit about 7/8 to 3/4 of a tank. Then it drops. I also seem to get better mpg on highway; it used to be the other way around. The battery never seems to charge all the way. I have done the following to try and improve the mileage:
Increased tire pressure Oil changes New tires Fuel injector cleaning Replaced air filter Checked the spark plugs Used Chevron instead of Costco gas Took it to the dealer to have the battery checked out Has anyone else had the same or similar problem? Any suggestions about what caused the mileage to degrade?
I found something online about the rear brakes causing drag and degrading the mileage on a Prius. That's my next step but I thought I also post here.
Any suggestion is welcome.
Class Action Lawsuit - Rx 450h
I own a 2013 RX 450h and from the day I purchased it I have averaged 24mpg, bouncing from 23-25mpg highway mileage, with anywhere from 22-26mpg city... a far cry from the 28/32mpg advertised. The dealership has reset my ECM three times, changed the inflation on the tires four times, and added a special spoiler and "areo fins", all with 0 effect. After pestering Lexus for over a year, I was told that 24mpg is NORMAL for this car, and there is nothing wrong with it. I have polled other 450h drivers and the vast majority state their mileage is the same, around 24-25mpg. Only 3 have said they get the promised 28/32mpg.
I intend to file a class action lawsuit against Lexus for artificially inflating their MPG rating on their hybrid vehicles in order to increase sales and justify the massive price difference between the hybrid and regular models.
I am polling all 450h owners, 2010-2015, to find out what their average mileage is. If a significant number are having the same issue, I will begin the process of filing on behalf of all 450h owners.
Again, this is only for 2010-2015 models. Thank you in advance for posting your MPG experiences.
Gas Mileage Improvement
By Marine Mustang
Just purchased a 2011 RX-350 AWD with 19,500 miles on odometer. Now at 20, 500 with several long trips planned next month. Currently getting average of 20 MPG in mixed driving (not heavy city type, but not Interstate) Used to get about 24 mpg city and 27 mpg road driving on a 2008 model, also AWD. Is there a method, adjustment, computer setting or other 'fix' for this that will improve the overall mileage? Have tried both mid-range and high octane fuels with no noticeable difference or improvement. I there an acceptable after-market product that would be beneficial? Thanks for the review.
Have around 1200 miles on my ES300h. Had an HS250h before. Got 32-34 average mpg for 3 years on the HS. Only getting around 35 mpg on the ES so far. While alot of city driving in Los Angeles area, I do believe the car is not getting advertised mpg, especially in light of the mpg on my HS which was rated 32-34mpg. What experiences are other ES300h owners having? I know all the hybrid tricks that worked on the HS. I notice the real time mpg indicator, when going 45-60 mph and running in Eco mode and gauge in Eco range is at 35-38mpg. Love to hear other owners experience before I talk to dealer.
