Prius (Gen 2) :: Car Won't Power Down - Bar Graph Shows Half Of Actual
May 17, 2011
I have strange electrical problems my 2006 Prius has recently developed.
It started off this past weekend when I went to shut off the vehicle after about a 5 mile drive. The car wouldn't power down, though, regardless of how many times I pressed the Power button. I then noticed that the wheels on the MFD were still turning, despite the car being stopped and in park. I shifted to drive, drove a few feet, shifted to reverse, drove a few feet, then back to park. Same problem. (Note that I was able to shift gears without any problems despite the wheels on the MFD continuing to turn.) I finally ended up leaving the car powered on for about 20 minutes, and when I returned the wheels on the MFD had stopped turning and I was able to successfully shut the car down.
I drove it several times with no problems, but then experienced the same problem again yesterday. Also, I noticed that the bar graph of mpg seems to be showing about half of what the car is actually getting. I was on a long trip, and the car seemed to be getting about its usual 50mpg, but the bar graph consistently showed ~25mpg. The "instant" bar on the far right of the graph was correct, as was the overall average displayed on the other page, but the graph itself was clearly wrong.

This morning, when checking the oil in my car, I noticed the brake fluid was about half way full.
Before doing the 5k mile service, I had noticed it wasn't full. I told the dealer to make sure they top it off, and they did. Now at 12k the reservoir is half way again. Rarely brake fluid should go down.

I just bought my 2012 Elantra Limited from the dealer today . The fuel gauge showed about two bars, a quarter tank I estimated. However when I went to fuel it, the pump clicked off after about 1 gallon, indicating the tank was full.
That was odd so I just figured there was some air in the tank or in the hose, so I tried adding some more fuel. I got about a half gallon more added when it clicked off again. Well, I know you're not supposed to top off the tank so I tried to add more. Got about two gallons added when it clicked off. I stopped fueling at that point for fear of causing damage.
My fuel gauge now shows a little less than half full. How can that be? Is there something I can do to fix this?

Just a quick question on my new 6.7l instantaneous fuel economy display (green bar). At idle, the bar is pegged at 40l/100km. When the vehicle is moving, the bar graph drops down to its proper 14ishL/100km mark.
At idle, the vehicle display should be under the 14L mark, because the engine is using little fuel. When the display is pegged, it also causes the number display on the graph (the instantaneous 14L/100 number) to creep up as well. In the span of 3 or 4 minutes at idle, the instantaneous average (calculated number) will creep from approx 14.5l/100 to 19l/100. So its pretty obvious the computer is using the 40l/100 number in its average.
Id almost swear that the display was working correct when the truck was new (2 wks ago), I've done nothing to change it, but for whatever reason its working backwards to what it should be doing (all my other vehicles' instantaneous display drop to almost 0 when at idle).
Its not the end of the world, and I can wait till its at the dealer next time to figure it out, but it is a bit of an annoyance. I am not in the middle of a regen or something like that either, AFAIK. Actual mileage on a tank of fuel isnt reflecting that 40L/100 figure on the display.

On occasion, on the power generation screen, I see just the motor applying power to the wheels. this only lasts about 2-3 seconds and I can't see any pattern to it (speed, going down grade, cold, warm etc). Is this normal?

On 2 occasions in the last week or so my GPS screen says "loading" on power up. It says not to turn power off as a status bar moves across screen. Never happened in the year Ive owned it, until now. A lot of personal settings get reset, including the time zone?

I recently purchased a used 2007 and have since driven 308 miles on it. There are currently 3 bars left on the fuel gauge, and the computer reports that I'm averaging 45.8 mpg.
However, I don't see how that mpg is possible because if I have been averaging 45.8 mpg over 308 miles, I should have used only 6.27 gallons...and 6.27 gallons is only 56.5% of the 11.9 gallon tank size, compared to the 70% that I've used based on my current fuel gauge status.

I got my first used oil analysis from Blackstone @ 48,000 km (roughly 30K miles). The oil has 8K km (or 5K miles). The dealer changed the oil so it's whatever they use.
The fuel comes back at 5.3%, whereas "normal" is < 2.0%.
Aside from that, other "unnormal" things include the Lead with a count of 9 (normal is 0), SUS viscosity is 50.9 (normal is 54-61), cSt viscosity of 7.54 (should be 8.5-10.8), and Flashpoint is 260 (should be >365).

While bucking a 30+ headwind on the highway @ 70mph, hit a pothole, got a check engine light and engine died. Traffic heavy and dangerous so I stayed on electric power longer than I should have to get off onto a service road. Determined my 12 volt battery terminals were very loose from vibration, I'm assuming. But now the car will not stay running when started. SOC shows 2.5%, main battery 0 volts.
Towed home, recharged main battery to 7.3vdc per module, yet car still shows same SOC and will not stay running. Currently, disconnected 12 volt battery overnight to see if things look better after system sits disconnected for several hours.

So computing avg fuel mileage. There are a lot of times display shows max of 99.9. Does the car use that number to compute av?. Or is that just the display's max and the car knows it is 155 or infinite mpg. (rolling downhill gen charging HV batt using no fuel actually more than infinite mileage)

Have a 1999 Taurus that has absolutely no power when you try to start. No interior lights no radio no dash lights nothing. This happened a few months ago but the alternator battery and ignition were all bad then. Replaced all those and for 3 months car has been fine. Yesterday stopped at gas station filled up and when i turned key . Nothing! Now if i turn headlights on and wiggle relay box under hood on occasion i can get power back and start the car.

Temperatures have dropped, and I am getting an icon that looks like a tent with a small snowflake in it - manual says "low temperature." My question is - what should I do? The icon persists after the car is warmed up.

As I'm driving along, the normal battery strength on the MFD shows 5/6 blue bars but occasionally, it will change to the last but one green bar and sometimes all the bars go green.
Everything else is fine, no warning lights etc.
Is this a normal?

The 2007 Prius starts and runs fine with no problem. However, the 12v battery check with a multimeter shows 9.9v reading. Does this mean that the 12v Battery is coming to end of life and needs to be replaced.

The speedometer on my 2013 Persona shows high by 2 mph. Is this caused by the 17 inch wheels? I wonder if the dealer can reprogram for this?

I have a 2008 Prius. I noticed that a large red triangle displayed briefly on the left when I started my car the other day. I know all the other smaller icons light up briefly but I don't remember the large red triangle lighting up. It and all the other icons go off after a second or two. Then the next time I started the car there was no red triangle. Then maybe the 3rd time I started the car, the large red triangle did again appear briefly. I took my car to my Toyota dealership but the tech said that is normal and means a door must be open, but that cannot be correct. I make sure all doors are closed and the "Open door" icon is not showing. I have already been through the water coolant inverter pump disaster so I admit I am a little paranoid about any funny things showing on my dash.
