Prius (2001-03) :: Emergency Broadcast System Type Alert Noise When Starting
Apr 10, 2012
Been driving my 2002 Prius since January 2005 and I've never heard this noise. It first happened Sunday as I was driving down the road, then this morning (twice) as I started the car. It lasts about 15 seconds for several "rings" of a shrill, electronic (definitely NOT mechanical) sound that reminds me of Emergency Broadcast System tests on the radio, or a really annoying cell phone ring. No visual warnings or lights are displayed (well, the Check Engine light is on, but it's always on, and my local Toyota dealership has been unable to shed any light).

Experienced the emergency flasher flash once or twice, when starting up the car (press brake + push start button)? What does these mean to my car? An error indicator? I've been facing this sometime but not too frequent, Toyota service guy said no error code appear in OBD?

My car has three codes P0102 - MAF or VAF Low Circuit Input, P0030 & P0050 which are signaling O2 sensor issues.
Car symptoms are a hiccup type sputter when accelerating for the first few times after starting the vehicle. The RPMs will drop down under 1000rpm and it will come back without taking my foot off the gas. The power comes back faster if I flutter the pedal. The last few times it stalled while taking off.
After the car is warm, it runs better smoother. I'm also noticing slightly poor fuel economy. The exhaust smells rich to me.
I'm wondering if there is a fuse that could cause all three codes? Seems like a power problem? Where is the fuse for these sensors?
Should I replace MAF? Can I use the MAF from a 2004 2.4L engine that's at the junk yard? How to proceed.

2010 Prius with 85k miles. Went to start car and here is what I get. All lights on dash come on including emergency icons. When I depress brake to shift into gear lights on dash go dim but not out. Car does not go into gear and neither does it show it going into gear on display. Heater was on and I tried to shut off the fan and again no response. Very difficult to get it to shut off. Pushed off 3 or 4 times and it finally responded. Been cold here in the teens and car has not been used for 3 or 4 days. Everything has been fine up to this point. No problems with anything.

I just purchased a 2011 Prius III with the built in navigation system. I also have a BMW 335i and am able to type in a destination in the nav system while driving. I noticed I can't do that with the Prius nav system and can only do it while parked. Is there anyway to bypass this.

I've been having this problem where as i'm driving (mostly highway) all of a sudden I get the feeling like i've let go of the gas pedal but I haven't. The mpg meter goes from about 40 to 100 as if its on straight battery power and I have to really press the pedal down to get any decent acceleration. Once in awhile i'll get the big orange triangle warning and the little pic of an exclamation point in an outline of a car. But after a day it may go away.
One time it didn't and I brought it in. I spent 80 bucks for them to find nothing wrong and say the alert had something to do with an oxygen sensor (its was awhile ago, i dont quite remember exactly)

2001 Prius. Within 15 seconds of starting the engine, I captured the screeching sound from the engine bay. Noise went away after about 20 seconds. New serpentine belt and new 12v battery installed. Pass dealer 27-point check. Transmission fluid, inverter fluid, high voltage battery were replaced about 18,000 miles ago. Current mileage 174,000.
Noise is not from the serpentine belt. I attached a mp3 file of the sound. "2001 Prius Noise.MP3" ..... Which component is making this noise?

I just bought my 2001 with 153k on it and I notice that sometimes it didn't appear to fully engage in park. What I mean is that.... If I park on a a small incline occasionally after I put it in park and take my foot of the brake..... It will pop into park..... Or I'll have to wiggle a little when I notice the key can't be removed from the ignition. Now that I notice this.... I can make sure it is fully in park each time.
My emergency brake cable doesn't work (and I always do use this religiously on my other cars), and I think having it reduces strain on the transmission..... But darn its near 300 bucks to replace I'm told.

My 2002 Hyd Elnta GT began making a rubbing type noise it begins about 20 mph and is loudest @ 40 mph I noticed when I make a curve to the right at high speeds it stops but I can still hear like something is still rubbing buts it's a smooth type rubbing sound. When I'm going straight the rubbing is loud like a rib rubbing but when in a curve it's a soft rubbing noise like it's rubbing something smooth.

I have a 2001 accent. I have noticed recently that there is a noise coming from the rear of the car. This is a rumble type noise which changes as I speed up or slow down ( It sounds as if it is something to do with the tyres)! I have changed the rear hub assembly and had the wheels aligned but the noise is still present. I have checked the suspension (by pushing down the back of the car) and it appears to be acceptable. Where this noise may be emanating from?

My 2007 Prius has started making an unusual sound. At first I thought it was some kind of pump or something, but now???
When I put on the emergency brake, the brake pedal or when I put the car in park or take it out of park and put it in D, it makes a "chuck chuck chuck" sound, not high pitched, but not a low sound either. It seems to be coming from under the hood on the left side. It sounds something like a belt slipping or a pump with a squeak maybe?
It does not appear to make this noise when simply depressing the brake while driving, so I'm not sure it's the same abs actuator issue.

Just got my new wheels. Put them on and synced the TPMS sensors. After a mile or so this alert comes on. If I turn of the car it goes away, until I drive another mile.
I got 20" wheels with 225-30-20 and 255-30-20. I see others with AWD on the forum running that setup.

2001 f150 xl with 151800 miles 5.4l had it for a few years now I get a humming type groaning coming from up front. only when in 4x4 and only at lets say 25 mph to 45 mph .seems to be worse when slowing down especially the slower you get then around 20 or 25 its gone. it is still quite noticeable on acceleration and after 45 its gone. Truck has always been a little noise while in 4x4 weather it was an issue that had already started or if that's how it is. This is my first 4x4 truck.

While the emergency brake was set, I happend to lean against the rear driver side of the the car and was surprised to hear a clanking, slapping noise coming from underneath the rear of the car; seemingly near the left rear wheel. What I think I'm hearing is the emergency brake cable (I assume this is a rear wheel cable brake) slapping against the vehicle frame or wheel axle. Even opening and closing the rear passenger door caused the cable to slap against the car.
This got me to experiment a bit, so I rocked the car back and forth and side to side. It's the side-to-side movement that causes the noise. The emergency brake works when set. The noise disappears when I release the emergency brake.

Took our 2005 Dodge Grand Caravan to a tire shop today. One sensor battery is completely dead, and when replaced, the other 3 batteries were too weak remove the alert from the information panel. Cost to repair all 4 is $400. Decided to live with the alert and they graciously put the bad sensor back in. Is there any way to disable the system? I check tire pressures regularly anyway. The continuous alert is agrivating.

After hearing some loud noise coming from my exhaust system, it was determined that there is a hole (from rust) in part of the cat. assembly. Three shops advised for replacement, there are no aftermarket products for this unit. I have NOT gotten any error codes, the only problem is the noise. What to do? The car is 10 years old with 86000 miles. I have been reading about some of you getting just the one piece and having it welded on, but I do not believe any of the shops here will do that, and indicated that it would be a very temporary fix.

So when I have any of the headlights on, and I then off my car and open the door, my Prius doesn't warn me that I've left anything on... Shouldn't my car beep at me to turn them off?

I just bought a 2001 1.8t passat and the emergency brake the other day stopped working. The button is pushed in all the way and will not come back out, so it does not click when the brake lever is pulled up and will come back down when let go of. The brakes do work when the lever is pulled however. Also, keeping the car in 1st gear while parked is alright? Even on a hill?

I have a 2004 Santa Fe with the 2.7L V6. There is a recurring issue where the ABS and Emergency Brake light come on, followed by the fuel gauge dropping to E, then all lights dimming until they go out. The car continues to run, but if you shut it off it won't start for about 30 minutes, then it start just fine with full power. The alternator and battery have been replaced twice in the last 10 months, most recently 3 days ago. The problem persists. I did find the right downstream O2 sensor to have broken wires which were causing a short. I replaced the O2 sensor and wiring harness, which cleared all engine codes, however the problem does still exist.

What a single beep followed by the word "Problem" across the top of the Touchscreen means? I can't find it in the manual.

I sometimes manually cut the headlights on during the day and I noticed that there is no bell or dinger that alerts me that they're on when the car is cut off. I assume the lights will cut themselves off after a period of time? Just concerned I might kill the battery if I don't notice I left them on.
