Prius (2010-12) :: MPH Display Went Black During Driving
Nov 3, 2011
During a recent vacation, while driving at night, the MPH display went black. I completed the drive to the hotel, resolving to change the fuse in the morning. When I started the car in the morning, the display was still black. I checked the fuse I thought should be involved (#22), but it was good. The MPG / MPG screen was still bad. Not wanting to drive an additional 400 miles back home without a speedometer, I called the closest dealership to get an appointment. The 2010 has 33K miles on it .
When we packed up and started the car for the trip to the dealer, everything was working. One week later and all is good. I plan on getting this anomaly recorded with Toyota just in case it happens again after the warrantee runs out.

I am due to make a 400 mile round trip business trip today. Go out and start the car, and the screen display is black. The MFD. None of the buttons on it work, either - I have the beep ON, no beep. I turned it off, waited about 1 minute and tried again, still nothing. Went for a short drive (took the dogs to the park where they can run), it was off for about 35 minutes. Still nothing for the short drive back home. I mean short, this is less than 2 miles one way.
I can still access the a/c and the radio from the steering wheel. I can see my speed, fuel etc, that is fine. It is just the display monitor. This came out of the blue, I have not noticed any issues at all.

I've owned a 2014 Prius Four (not IV, Roman numerals were for model year 2010) w/o Nav for just about a year now. I've encounter this mysterious condition three times now where when I turn on my car, all I see on the front displays are the READY light on the far left and the mini-display that shows the shift pattern.
* Both the speedometer/fuel gauge display on the left of the shift pattern display and the "Hybrid status" display on the right of the shift postion display are OFF.
* The car operates normally (it's not in a limp-home mode).
When I first encountered this issue and reported it to my local dealer, they suggested I take a video of it with my smartphone. I did so the car (and a copy of the video) is now at the dealership.
The second and third times this issue came up, I took videos and did some additional testing.
- When these two displays are OFF, there is no backlight to the climate control LED display underneath the stereo...
- I normally drive the car with the headlamps in "AUTO" mode. When you shift the headlamp switch to "DRL off", the two missing displays automatically power on. In any other position (Auto, corner marker lamps only, or headlamps ON position) the two displays in question turn off.
- The issue isn't with me accidentally turning the dimmer switch too low. When the dimmer switch is set to max low and the dash light sensor is covered (emulating complete darkness outside), all three displays on the dash (including the shift position display) are barely visible/look off. As the service advisor saw in my video, that's not the case.
This is clearly a safety issue ("you cannot tell how fast you are going" and "you cannot tell easily how much gas you have left without going through the infotainment display) so for now the dealership at least seems to be on my side in that something needs to be repaired. The good news is that now that the issue has been documented in my service history, they did comment that it will get fixed eventually even if the issue comes back after test. For now, the dealership is stumped so they asked Toyota for guidance on what parts to try replacing.

Aside from spending $ to have the polarity reversed on the HVAC display, is there anything be done to darken the display letters and numerals? In the daylight this thing is unreadable. Very poor design by Toyota. Any little tricks that I don't know about?

my sister has a 2003 accord v6. shes got about 70,000 miles on it. recently the radio display went black and nothing is visible. at the time the display went out, the audio was still working, just no display. if i recall correctly, it also displays the controls for the heat/ac controls also. Unfortunately, after the display blacked out, she had a separate, unrelated dead battery issue. a new battery was installed but now there's nothing because of the built in security feature that kicks in when the battery is disconnected. What the actual part is called that needs to be replaced? from what i read, its not the radio unit itself.

Today when I am driving the 2007 Prius, suddenly heard some noise. I managed to come home and checked. There is a black plastic piece hanging and touch the ground, the noise was from this black plastic piece touching the ground. Attached is the picture.Is this a big problem? Can I continue to drive the car to repair shop to get this fixed?

My 10 months old 2011 Corolla started acting up. Two days ago I noticed the light on the clock is gone, so now I cannot see time at night or when driving in a parking garage.
Today in the morning I turned the headlights on and oops...the radio is playing fine but the display is black. If I want to see station #'s, I have to turn off the lights.
What's wrong with the clock light and radio display? Do I have to take to the dealer right away or can it wait until I go for an oil change in a week or so?

Was driving the last week and happened to look down and notice the display for my climate controls was completely black. They were still running at whatever I had them last set at but couldn't change anything or turn the system off. Pulled into a parking lot, turned the truck off then started it again and everything was working fine.
Couple days later, was driving down the road again, glanced down and now my climate display, stereo display and odometer display were all black but once again everything was still functioning, just couldn't change anything. Turned my wipers on to check those, heard a little click, and all the displays popped back on like normal???? Wipers worked just fine too.
I'm assuming a short somewhere but wouldn't even know where to start to look or if it's even within my limited skill set to try and track down.

I have slightly over 1000 on my new Prius and have been resetting the Trip Counter A at the last couple fill-ups. But the display doesn't show the MPG. How can this be fixed?

Any technical difference between turning the ECO diplay "on" or "off" when setting display options? I know when "off", the ECO sign does not show but does it also mean the car runs differently? Is this just a way to avoid having that thing show up?

I can use the wheel to dim during the daytime but can only dim can't turn off the display like I can at night. I've tried turning the lights on and adjusting the wheel but still can turn off all the way.
I would like to turn it off and just use the HUD.

just purchased my 2010 IV a few weeks ago and have noticed some smudges on the display where you get your graph for fuel economy. I had thought they were just finger prints and they would wipe right off. Come to find out they seem to be smudges behind the plexiglass. How they could have gotten there. It's a little annoying and I would live to clean it up. The smudges are most noticeable on the right side towards the top of the graph with a smaller smudge on the left side, also towards the top of the display.

The small LCD display (Int temp, fan speed, etc.) in my Prius IV with Nav Package is very dark, read "unreadable" when sunlight is prominent in the car. This is so even with the panel rheostat turned all the way up to bright. Is this a faulty display or is there any work around if not?

My last fillup was for 9.539G and I had 501 miles on that tank (I had reset the Trip B display after my prior fill-up). This calculates to 52.52 MPG. Yet the trip B display had said I was getting between 55.5 MPG.
This has happened every time I've calculated my mileage, I'm not getting quite the MPG that the dashboard display says I am getting. It overstates my mileage by 3-4 MPG.
