Prius (Gen 2) :: Radio Wouldn't Turn On - Power Button Doesn't Do Anything
Feb 21, 2011
My radio was working fine on Friday, but the next time I drove the car, on Sunday, the radio wouldn't turn on. The power button doesn't do anything, pressing the mode button doesn't do anything and the voice command button doesn't do anything.
Everything else works... bluetooth, display, Nav. Just the radio/CD player won't turn on... it just says "Audio Off". Also, when I go into the diag screen, the Audio reports "NCON". I've checked the fuses listed in the Owners Manuel as audio and they all seem fine.

My 2011 Prius II hasn't had any issue for the 3 years I've had it until two days ago when the car simply wouldn't turn on. The battery would "whirl" when I would press on the brakes but when I pushed to power button nothing would happen and the Ready light would never come on. The power button didn't have any color (orange/green). The batteries were charged and would spark when cables were connected to them.
I tried it again about an hour later and it worked fine. I drove it for a couple minutes and parked it hoping that it was a fluke. Another hour later I tried to start the car and the same problem as earlier happened. I decided to tow it to the nearest Toyota dealership to get it examined/fixed, but after they've had it for 2 days now they cannot get the car to reproduce the same symptoms.

Here's an odd one. On our mildly cold winter mornings ~12 degC the radio on button doesn't work. This is regardless of the power status the night prior. What's even weirder if that if climate control is off and you turn it on the radio button is fixed. Earth leak, cold temp resistance, 12V battery?

I noticed today shortly before turning off the car that the screen was lagging. Sometimes there was not even response. Radio turned on and off ok, but screen was not showing it. It would then display (after several seconds) the info, display, and audio. However, when I clicked the Climate one, the MFD said, "Check the condition to the air conditioner." However, when I used the driver's controls, it worked okay.
I then turned off the car, and when I turned it back on, everything appeared to be normal. The screen was significantly lagging.
Might this be an issue with the air conditioning itself. I mostly run the A/C on full blast on the MAX cold (sometimes Auto (LO temp, HI fan)). Temperature in the output vent (left center one) after 5-10 minutes: 48 degrees moving. Outside temperature between 100 and 110, so it's pretty hot too.

This started about 2 months ago. About 10% of the time when I depress the brake and press the Power button, all the dash lights come on except the Ready light (it acts as if I pressed the Power button twice without my foot on the brake). When I depress the brake a second time and press Power button again, the Ready light will still NOT come on. I have to press Power button with foot off the brake to shut off the dash lights (the car is effectively off) and then when I press Power button with foot on brake a second time, the Ready light will come on. I effectively have to try to start the car twice. I also noticed that the interior lights are dimmer when I open the driver's door until it goes through it's normal noisy gyration (something to do with the brakes?). I'm thinking that the 12-volt battery is starting to fail. Does my Gen III 2010 Prius have a diagnostic tool to check the battery?

Drove to a friend's last night. My wife had the key in her purse, but I was driving. After we all got out of the car and shut all the doors, I couldn't lock the car with the outside button. I eventually opened the door & locked it. After coming back out, the car unlocked fine and started fine, so the SKS was working.

Just got my 06 Prius. The screen shows that Audio Off. The radio doesn't want to turn on. What could be the issue. 06 Prius with nav, Bluetooth, JBL etc. Everything else seem to work except the radio. Fuse perhaps?

My Prius engine wouldn't shut off when the button was pushed. The Toyota dealer was clueless.

2010 Prius, ~250k miles, pressing power button to turn off on results in a semi-regular "pulling the plug experience" instead of a graceful shutdown displaying the mileage and time, can happen a couple times in a day.
IGCT relay and both integrated relays replaced in the fusebox, as well as power switch. Takes between 2-90 seconds to recover and turn back on. Lights out and dark during that period. No codes shown in Techstream.
Sometimes is bad enough that the Nav system reloads the DVD and settings. However, bluetooth and all other functions work once it's up and running. HV battery replaced last year, as well as 12V battery.

So, I decided to re-code the car such that the radio does not shut off when I turn off the engine (KESSY) but rather when I open the door to get out. It's accomplished by recording the instrument cluster to think it's a UK cluster. Well, when I did that the area that usually displays the outside temp is displaying my speed in KPH. I changed the coding back to US and it didn't work. The temp is displayed if I choose to have the car stats displayed like miles till empty and such but that's not usually what I have displayed. Funnily enough, I do like knowing what the outside temp is.

Ok, so, according to my dad, his car battery died, and he had to have it jumped. After the jump, apparently his headunit will no longer turn on. We think it may be a blown fuse, in which case we need to know the location of the fuse (and probably the rating & label of it, for identification's sake). I have an aftermarket headunit in my Santa Fe, and the fuse for that is in the back of the actual unit itself, so I don't know if there's a fuse in the back of his factory stereo too...? However, we are not exactly sure what the problem is. My dad's car is a 2007 Hyundai Elantra with the premium factory audio system installed. He gets Sirius-XM and has an aux input (everything pertaining to audio is factory-installed).

My dashboard goes out periodically then magically is restored. They say to replace that. I've decided just to trade it in and get a non-Prius. This morning, however, after driving for a short time, I pushed the power button to turn off the vehicle and it only partially shut off. The key wasn't in, so I put it in and tried again. Now it says there's no key in the ignition and still will not turn off nor turn on.

2005 Jetta Gli 1.8t. It decided to do some funky things on me today. I has been running perfectly fine up until I went out for dinner.
When I came back to start her up. Everything worked except for: Radio, Low Beams (both) Fogs, windshield wipers/fluid, rear defrost button, turn signals (but hazards worked fine) and the fan for my heater.
What was working, oddly enough are the amber lights, tails and brake lights, all other lights including the high beam, but ONLY in the position when the stalk is pulled toward the driver. (Have to hold it to keep the high beams on).
It's not the battery because my car wouldn't have started at all if that was the case. It's not the alternator because I disconnected my battery and the car ran just fine and never died. I checked all the fuses of the things that went out but nothing seemed out of the ordinary and all of them seemed just fine.
Where to look next or what to do. I have no check engine lights, or any lights for that matter so I have nothing to scan.

I've had a Prius (2nd generation) since 2006 and have been thrilled with it.
So today, I purchased a Prius V (three, I believe). Very happy with it in general so far, but incredibly disappointed to discover that some of the features I have most enjoyed about my 2nd generation don't seem to come with my version of the Prius V.
On my Prius (2nd), I can unlock the hatch (and all other doors) simply by depressing the rectangular button with the key FOB in my pocket. That does *not* work on my Prius V and everything in the manual and what I can find online says that it *should* work.

Sometimes when I hit the start button it takes a couple of minutes for the AC to start blowing air. I even tried stopping and shutting off and restarting but it still took a few minutes to start blowing. It doesn't do this all the time just every now and then.

Found this by accident. If you push the power button with the car off the radio turns on. Checked it twice to make sure I wasnt imaging it. I can't be the first person to do this right?

I have a 2006 Prius with about 53,000 miles on it. For some strange reason, about 2 times a week there will be no sound at all from the FM radio. The AM radio works, the CD player works, and the AUX in works fine, but complete silence from the FM stations (not even static or a hiss). If I turn the unit off and back on again over and over, the FM will eventually come on and work fine.

How to fix or solve front turn signals that are not working? I just realized that both the front signals on my Prius doesn't light or flash when making a turn, the rear are working fine. Is this an easy fix or should I bring it to the dealer?

So the PO tells me he was flying down the highway and went to cancel his cruise control and it wouldn't turn off. He claims he made it to the shoulder of the highway and killed the ignition. When he restarted the truck is was turned off and it hasn't been used since. I tried to use it yesterday but couldn't get it to work?
So I do the search and find out that the deactivation switch is most likely the issue. I just picked up a new one today and was curious if it is just a R & R thing or if it needs to be bleed off or something? Is there a need to test it or just change it out? Sound like something that would cause these issues?

In June my Grandfather picked up a used 2010 Prius (not exactly sure what trim package it is? I think it's IV? It has heated front seats, voice activation, bluetooth, navigation, XM radio, NO sunroof though)
He honestly doesn't like the car that much, I don't think he knew about the "PWR" button that would make the gas pedal behave more like a standard throttle, but he is away on a trip right now so I am borrowing the car. I love it, and I'm going to show him the "PWR" mode when he gets back and see if that changes his opinion of the car.
ANYWAY I noticed when driving it that pressing the MAP button doesn't actually make the map display and instead changes the radio station? I did some searching and found that this may actually be a known flaw although from my searching it doesn't look like Toyota has addressed this?
I'm guessing the car is probably out of the original manufacturers warranty? Not sure if there might have been some sort of warranty from when he purchased the car pre-owned? I definitely plan to talk to him about this when he gets back because it is very annoying to not be able to switch back to the map easily. The only ways I have figured out to work around this is use the voice activation and say "show map" or to press the "DEST" button, choose a destination, and then delete that destination and then it shows the map.
