My Prius's horn goes off intermittently few times during the day and night. It is happened every hour and the horn goes off repeatedly 6 time "Pi-Pi-Pi-Pi-Pi-Pi". I don't know why horn goes off intermittently. I checked my car, but I cannot aware any problem so far.
View 3 RepliesI have a 2010 Prius V that is honking the horn in the middle of the night and sometime in the middle of the day ( 5 short honks of the horn). This has been occurring over the last few months.
1. Only one key FOB and it is stable ( not in a pocket or something pushing a button)
2. Car is confirmed to be locked before this occurs.
3. No alarm issue from what I can tell ( I get up right away and no one or animal is around the car)
3. Cannot find root cause on a current thread although one person stated that it might be that the 12 VDC battery is starting to go bad???
No other issue with the car.
I just purchased the car a few weeks ago. Horn doesn't work till I press about a dozen times and "get lucky".. Once it hits once I can usually beep about 4 times before losing it. I checked the fuse, looks fine. Haven't found the relay yet.
I suspect it is something in the switching/contacts/ground in the steering column. What I may need to replace in steering column?
My wife was driving our 2012 Prius C that we bought new three months ago and as we were backing out of a parking space the horn sounded in a stuttering pattern. She stopped and the horn did too. As she continued to back up the horn stuttered again, this time I was watching her hands and the steering wheel. She was not touching it except in a normal driving manner. Nothing touching the center of the steering wheel. Looking over the dashboard displays we saw nothing abnormal.
As we drove out of the parking lot the horn fully sounded for a split second then stopped. We turned left onto the street and as she straightened the wheel the horn started blowing like it was in alarm mode; on-off-on-off. We pulled into a parking lot, shut off the car and the horn stopped. Drove 12 miles home with no further problem.
In my new to me 99 F250 SD ,Started today off with switch sticking in drivers door causing dome light to be on when doors closed... oiled the crap out of the door mechanism and it started working. Later in the night I look out side notice the radio lights on with no key. Can't figure it out so pulled the face off and figure I'll look at it tomorrow and go to bed.
1:30 am the horns blaring! I open drivers door and horn stops, close it and it goes off I ended up pulling the batt cable so I could go back in the house. I did search for info with no sure real causes. Seems like it has happened to others as well.. BTW it did start raining before the radio stayed on. Thinking water in the dash or fuse panel. But it doesn't explain door switch problems I had earlier. Maybe 2 separate problems. This will be fun! Not!
I own a 2010 Prius that now has over 90K under its belly (got it new at around September 2009).
While driving at night all of a sudden the central LCD panel (Odometer) shut down. The right panel is perfectly fine.
Is there a solution?
2010 Prius IV. Map display not adjusting to night mode when her headlights are on. I tried looking at my 2014 Prius Three, not III because it isn't a 2010 and only 2010 used uppercase Roman numerals for model designation, to guide her through it over the phone but her menu options seem to be very different from mine as she didn't have an options button on her map.
View 2 RepliesHow do you get the Navi Screen in a 2012 to go into night mode at night? Where is the setting to adjust this so it automatically goes night or day at the right time? Also is there a way to adjust the brightness of the main mph screen (multi information display)?
View 2 RepliesI am very happy with my 2010 corolla, except for the annoying beeping. I live in a very quiet townhouse row and the cars are parked right in front of the houses. So, when I get up in the morning to get in the car, it beeps when I unlock it and on good weather days when the windows are open, there are at least 20 units that can hear it. It is very embarrassing. What is worse, randomly in the middle of the night, at 230 or 3am, it will beep five times quickly. My neighbors want to kill me! The engine light has been on for a few weeks because I am due for an oil change. Could it be related to that? And how do I turn this thing off?
View 4 RepliesI imagine it's due to evaporation that happens overnight... Is it?
View 6 RepliesI have a 2010 Model I with only 19K miles on it (purchased new). For the past year or so, at any time throughout the night it will give out 5 beeps for apparently no reason. I have reset the system by disconnecting the alternate battery and have used a PocketScan Plus to test the systems which shows no problems.
View 5 RepliesI'm having an issue with my Nav system. I'm not sure if its going out or if it's due to the cold weather but it doesn't immediately come on when I start the car. At some point while I'm driving I'll notice that it's on and working but it seems to also be intermittently switching between the day and night time screen mode. How to check to determine if it needs to be replaced or if there is a fix?
View 4 RepliesI just bought little bit bumped Prius 2010. The bumper, Windshield, hood and left headlamp need to change. And three front airbags and belts.
But this is not problem, the problem when I start a car the horn is starting beeping. When car is not started it shows lock with keys icon on dashboard. When I start it, it shows only airbags problem, and starting beeping. Car run and drive without any visible problems.
I have 2010 Prius, package 2. My horn stopped working a few months ago. I never got around to seeing whats wrong with it. I am not sure if it is the fuse or what ever. Where the fuse box is? Or what it can be? I did have a back up camera installed shortly before it went out...
View 2 RepliesI have a 98 Grand Prix 3.8 with about 170,000 miles on it. Yesterday I tried to start it, and it would crank but not start. Let me provide some background info . . . We had received cold temps and snow recently and the vehicle is parked outside. The car ran fine the day before in colder temps. Yesterday morning I was scooping the snow next to the car and I bumped into it causing the alarm to go off. The horn honked 4 or 5 times and then stopped. Later when I tried to start it, it would just crank. At first I thought it was the fuel pump since I could not hear it. The fuse was fine. I then noticed the DIC was flashing 0 on all modes.
On another thread I saw that is often due to a loss of data between the DCI and PCM. I thought perhaps I tripped the security system when I bumped into it which is preventing it from getting fuel, and perhaps was also causing the DIC to show 0. A GM service tech said to put the key in the run position for 10 minutes then turn it off, and then do this two more times and that should clear the security system and the car should start. I tried it and it did not work. I am starting to think it may be a bad PCM. Stopped at my local Oreillys to check out their code reader, but they no longer check them out to take home. It must be used there.
After washing my car this morning, I pulled it into the garage, pushed the park button, then the power button and got out of the car. Shortly after entering my house from the garage the horn started sounding very loudly. I grabbed the keys and ran back out to the garage to see what was wrong. I pushed the power button again but it just went to the accessory setting, then I powered up and checked to be sure I was in park, brake set, no door open. When I pushed the power button again, the horn stopped and everything seemed to be normal. I checked some other threads but they seemed to be about a horn alarm. I have not had an alarm activated that I know about.
View 4 RepliesWhen I drove my 2012 Prius 3 today, the fuel indicator was flashing as I had about 20 miles until empty. I was on my way to get gas when suddenly, the horn was honking as if the alarm was going off. Nothing I did seemed to stop the horn, even clicking the unlock button on the key fob. Intermittently, the horn would stop, then start up again in a stuttering fashion, only to be followed by the incessant honking I mentioned earlier. I have a video of this but it must be too large to upload.
View 6 RepliesWe also noticed when depressing the horn to actuate it in the straight position, there is hardly any movement. When in a rotated position, there is a definite actuating movement or depression of the horn. There something happening when it's a straight position, the horn is being prevented from making contact so the horn will work.
View 5 RepliesMy horn seems to be working intermittently (more often NOT working...).
When I press the steering wheel i hear a click, but that's it. I've checked the fuses already and nothing is blown. all the buttons on the steering wheel work consistently. Another data point that may be relevant is that i went in for the clock spring recall a couple months ago.
How to troubleshoot and find the cause?
While driving the key not detected message appeared three different times during a 50 mile trip. The message lasted approx. 30 seconds.
View 7 RepliesLast night the TPMS light came on on my month old 2010 Prius. I checked all the tire pressures and they we @ 38 rear and 40 front.
TPMS light went off after 4-5 times of turning the car on/off.
What might have been the problem? Is it something I need to be concerned about?
