Lexus GS 2006-11 :: MPG Average Not Correct / Too High?
Apr 1, 2015
Just recently I replaced my spark plugs, cleaned my throttle body and mass air flow sensor. I cleaned both with its recommended cleaner. After that, for a few days the vehicle was acting up in terms of the rpm was jumping up and down when i was coming to a stop. It was also idling high most of the time when the engine was on and on park. After a few days the car settled in and operates fine now. However, now when i check the avg mpg I'm getting about 20-21 city and highway. This doesn't add up.

My 2006 GS300 has oil burning issue after 80k miles now my odo is at 110k miles. I have changed my oil every 5000 miles, keep burning about 1 quart every 1k miles average. Literally burnt about 20 quarts of an oil with premium fuel. At 105k miles, I had replaced my bank 2 sensor 2 after the check engine light and vsc light came on, reset the code those lights came right back on.
Check the code again, found out bad cat converter between passenger side sensors. The recalls has been done at 65k miles at dealer. My questions are :
-What would be the cause of burning that much of an oil? No leaking on floor or bad smell.
-Is burnt oil causing the failure of cat converter?
-If I replace the cat, will it go bad again?

I have a 2013 Accent and have installing driving lights. I am looking for the correct high beam wire on the driver's side on the headlight assembly. I will then run this to a relay so that when I turn on my highs, the driving lights will come on. I have tried to locate the correct wire but the one wire that is hot when the highs are on, is still hot when the car is off as well as the lights.

We've had our 2013 RX350 CPO for about a month now. We traveled to NC a few weeks ago and I noticed that the speedo would read 70 but the computer Ave. MPH would read 4 mph less. This was using cruse on the highway. In about an hours time I zeroed the Ave. MPH a couple of times only to have the same result. It still is happening at any speed. Is it a dealer issue?

A couple weeks ago, the "average fuel economy" display on my 350 F-Sport disappeared - when I'm looking through the different displays, it skips straight from "average speed" to "current fuel consumption". All the other displays are still there, so I'm not sure what caused this. I'm wondering if I'll have to bring it in to the dealership.
Some info about the car: It's a 2014 IS 350 F-Sport with ~6000 miles, and it just had its first service a few weeks ago (shortly before this problem started).

Everyday when I start my car the time is 3-5 minutes behind. I reset it each time and I'm still having the same problem. I have a 2013 and it's the original battery if that might have anything to do with. I just tested the voltage and that's good.

I was playing around with the navigation system of my 06 RX400H because I read about the motion override online; however I was being stupid and chose the wrong option under the "load" menu, so the navigation system kept telling me "insert correct disk. ". Hoping that I could find a simple "reset" option there, I was playing with the diagnostic mode quite a bit. One setting allow you to select the navigation unit start up logo between Toyota, Lexus, and None. There is another interesting option called "car setting" don't know what it does.
Seemed like it let you toggle between a numerous of settings, I remember one being 9001X4WD or something. I didn't know what the setting does and accidentally changed the vehicle setting for my navigation unit. After confirming the edit, I realized that the mapping for all the buttons on my panel completed changed! First of all the map button (which wasn't working at the time because I had the wrong load option) became the "Audio" button that is similar to the audio button on my other car, 06 IS350, it showed me all my audio presets and I could choose using the touch the screen (normally this feature is disabled for RX400H).
I realized I might have screwed up the setting and wanted to change back to the original vehicle setting. I couldn't find much information online, so I figure I probably hit that set button by mistake 2 or 3 times, so I reverted the car code back to what it was 3 selections ago, and bam! My panel buttons are messed up even further! Now I don't even have access to the "info" button any more! I can still get access to the first level diagnostic mode using the "display setting" (display key is mapped to the info button now) then left upper corner + left lower corner method, however I can't change the vehicle code in this mode.
I took the car to a local dealer, and the service tech was like "what the heck did you do" and he said he don't know how to fix this except to replace the whole navigation ECU which would cost thousands of bucks. I asked him it would be as simple as getting access to the onboard ECU memory and rewrite it and he said the data format is Toyota proprietary and the dealer doesn't know how to fix it.
Of course I wasn't satisfied with the answer I got, I took the car home. Following some good information on forums and navigation ECU replace instructions on AllData, I was able to remove the navigation ECU from the car, then took it apart, disconnected the power daughter board, pushed the black reset button(?), and then put everything back together. I have seem people saying this method working and not working, but for me it did work. When I restarted the vehicle, the "loading data do not turn off" screen came on, and after the system booted, GPS navigation is working as usual now. On e interesting observation, before the GPS unit has established a connection with the satellites (took about 2-3 minutes to do so), the default location for the vehicle in the system is somewhere in Washington D.C.
Now I have undone my "load version" mistake. However, without the "info" button being mapped to the dashboard, I don't even have access to the menu where you can change the "car code", so even if I know the correct code now, I wouldn't be able to enter it. also it seems that I was able to reset the ECU when I took it apart, I am suspecting that the setting for "car code" isn't store in the ECU but it is stored somewhere instead.

My car rides smooth until 75-80 mph. At that speed I get a slight but bothersome vibration. I've had the front wheels rebalanced twice and even got an alignment (though usually have no effect on vibrations) but it's still there. I didn't know what to think. Last nite a relative called to ask my opinion of the very same issue he is having with his 08 GS. Almost identical. He says his vibration starts at 80 but ends at 85. He is on stock wheels so my 20's seem less likely to be the problem. This is a recent occurrence. My car has been smooth for 4 years.

I noticed yesterday my AVG MPG was stuck at 20.3... I drove hard, drove light, and it remained there at 20.3. My Consumption was registering normally activity as well as all other functions in the MFD. The car sat over night and is still the Avg MPG is stuck at 20.3... short of pulling the battery to hopefully reset the MFD, whatelse could it be... and why??

I deliver mail out of my 2014 Prius C and noticed that my MPG is only about 30-35 MPG? What am I doing wrong?! I thought stop and go driving is the best way to get the best MPG?

I can't find the average mpg display anywhere. On my 2008 I could hit the info button and it would display your average mpg but on my 2013 Prius 3 there is no reading for that, at least I can't find it.
In the owners manual there is a pic of one of the display's that has it in there, but I can't seem to find that display anywhere.

That MPH average at the bottom right of the screen. Is that actually show the average miles per hour that you have driven? Mine is currently displaying 24. I never drive that slowly, much less often enough to average out my usual 55-70 driving. What is the purpose of that display?

I have a new 2015 Prius five and can't figure out how to determine average mpg. In my 2007 model, there was an info screen that displayed average mpg that was reset each time you refilled the tank. With the new Prius this screen is gone and all I can find is a display showing average mpg for the last 5 minutes.
