Prius (Gen 3) :: 4 To 5 Beeps In A Row From Horn For No Reason After 2 To 3 Hours Of Parking
Jul 28, 2011
I am not sure if it is the same time every night like clock-work or if it's a set interval after I come home...but here is what happens:
-I come home and I turn off the power to my 2010 Prius after parking.
-I lock the car and I get that loud external "Beep"
-Around 2 to 3 hours later, I hear 4 to 5 beeps in a row from the horn. It sounds just like the beeps that are made when I unlock the car. Just a bunch of them in a row..for no reason
It is really loud and ticking off my neighbors. What would cause this? I have a dealer installed Rockledge security system.

I 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.

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.

We have a 2000 SL1 that started having the horn go off (continuous, not intermittent beeps). The first time it happened was early in the morning, lot of moisture in the air, and it stopped when I hit the middle of the steering wheel. The second time it happened was during the night (again a lot of moisture in the air) and my son unplugged the horn.

Got a '13 FX4, sometimes my remote start works and sometimes the horn just beeps when I go through the sequence.
Am I doing something wrong, leaving a door not shut all the way etc.... Are there any parimiters where it won't remote start and just "beep" the horn?

My 2.0T 06 Passat misfires sometimes during cold start after 6-8 hrs of parking. It happens very rarely. I have had the car for 4 years (bought it brand new) and the misfire has happened about 5-6 times. Is this normal? Just wondering if they get logged in the computer system so VW Service can see it? My car has got 47K miles on it.

Ok so i get off work and i go to my car, its around 6ish and its reading 36 degrees fahrenheit. On start up the car beeps and the parking brake wont disengage...tried pressing the button a couple times but nothing. So i turn it off and start it again...nothing. Then finally turn it off, let it sit till all the interior lights come off. Turn it on and lo and behold it works! At an ambient air temp of 36 degrees, is it possible that rotors and pads are frozen? Also could it be that the cold temperature is freezing the brake lines? Also the car was parked so that the wind was perpendicular to the brakes. So like a T with the long part being the wind!

I have an 03 JETTA TDI 5 SPEED WAGON with 216 on it. The parking brake alarm recently came on for no reason (as did the warning light) As soon as you move 50' it starts and wont stop until you stop the vehicle. I pulled the center console, unplugged the switch and it still did it. I jumped the 2 wires together and it still did it! I cut the wires at the point where they disappeared into the larger harness, it still did it!!! Why this is happening and if there is something besides the switch at the park brake lever that make the alarm go off?

About 2 months ago my Touareg was rear-ended. I just got it back from the body shop and am finding little things that are not the same and I am wondering if they just need reprogramming or if these could be a bigger issue (going back to the body shop today)?
1. They replaced the entire liftgate, but the rear wiper is not working even though the washer fluid does.
2. The interior lights are on, even though all doors are shut, when the switch is set to the open door setting.
3. There is no beep when I lock my vehicle with the keyfob, but the lights blink.
4. There are no warning beeps for the parking sensors, even though the dash lights up.

Whenever I start my 2011 Sonata Turbo after it has been resting overnight, the brake warning light comes on and stays on. It's not immediate?it usually takes five to ten seconds, and whether the emergency brake was on when I started has no effect. Once it goes on, it cannot be shut off without shutting off the car and restarting?at which time it acts normally for the rest of the day. The braking system is fine.

My poor 2000 Chevy Monte Carlo SS is turning into a hooptie. Or at least it sounds like one. I am due for a front brake pad change in about a month, so I'm wondering if this new noise has anything to do with it. If not, I certainly hope it's affordable!
And now to the strange noise being emitted from the front of the car. This morning, about 50 degrees, I started my engine to drop my boyfriend off at work. While idling in the parking spot, I heard a dim car horn - fog horn combo noise. A neighbor gave me a "wtf" face, and I'm sure I returned her stare with the same expression. Hoping it was something else, I drove off.
First stop light, just down the block, while idling and waiting for the light to turn green, I hear the same noise. Very embarrassing. Next light I stop at, same noise. Once the car got to half of its optimum temperature, the noise stopped and didn't return.
That is, until several hours later when I needed to go to work and restarted the car from a cool nap. Same noise.
So, what the deal is? I thought it might be fan related, as it kind of sounds like there is some rattling going on in there, too.

About three days ago, while taking the dogs out, I go through the garage, which is not heated, and I notice the Prius is making a noise. It sounds like an electric motor running but I can not figure out where exactly the noise is coming from. It had been raining, and the car was pulled in the garage wet. About 5 minutes ago, I heard the same noise while getting the dogs in from outside. Both times I came back in the house, grabbed a FOB, and hopped in the car and put it in ready mode. I immediately shut it off, and the noise was gone. It reminds me of the sound that the car makes when you open the drivers door, which I think is the master cylinder pressurizing. It is about 7 degrees F here, but I am sure it is a little warmer in the garage.
The car has about 33K miles on it. It gets driven everyday. Today, I got home about 4:30, and this just occurred at around 9:45. Whatever is causing the noise, I am sure will put a drain on the battery, as it definitely is an electrical motor of some sort running, which will take some power. I would hope that the power was coming from the 12 volt battery, and not the traction battery, as it usually disconnects a minute or so after the car is shut off. The car was definitely shut down when I drove it in, and every light was off on the dash when I got in to power it back up, except for the flashing lock light on the right side of the display. The wind chill here tonight is supposed to go to -25 degrees F. I am concerned about the car starting if it pulls too much power from the 12 volt battery.

After an oil change at the dealership, I checked the oil level in my garage after the car was parked overnight. The level read way past the maximum fill line.
