Prius (2004-09) :: Slow Then Fast Paced Beeps While Driving Without Any Visual Warning
Jun 5, 2016
My 2nd gen 2007 Prius started to show a strange behavior today and I don't find any answer to it. While driving without any cars close, with all seat belts closed and nothing on the passenger seat I started to hear slow paced beeps (approx. 20) then fast paced beeps. When I switch off the car and started it again I got the same beeps after approx. 30 seconds. I never got any visual warning and the OBD reader doesn't show any error code.

A 2010 Prius III: Its been a few days now that its doing this.
While I'm driving, the car would start to beep fast (3-4 beeps per sec), the brake and steering wheel stops working, its very stiff and brake pedal is hard! Along with that, there's 4 lights came on the dash; traction control, abs, brake and tire pressure. All this happens when the car starts to beep, and the beep last anywhere from 2-5 second, constantly!
I checked everything and its normal, gas half tank, keyless key is in my pocket, all doors closed, brake pads looks good, tires are good. I've had this car for 4 years, its at 45k miles.

I have a 2005 prius with navigation, smart key, hid lights; not sure what the package is called. Today while driving I heard two short beeps that I have never heard before. At first, I thought it was my Ipod or cell phone. I turned off the radio, turned off the climate control and drove until I heard it again. Two barely audible beeps; the second one about 1 second behind the first. I put the car into the diagnosis mode via the nav screen, ran a test and all checked out ok with the exception of the audio h/u has a yellow box with the words "chek" in it. When I press the yellow box it doesn't show any error codes. I'm not too worried about it but it just started happening today.

My 07 has 149K on it and I never have checked the oil. I do have it changed every 5K and no one has ever mentioned it coming in low. My last oil change was at 145K and about 2000 miles later the master warning light would come on when I slowed down fast, especially if there was a turn. I noticed this on the twisties driving up the west coast. The problem then went away after a couple hundred miles. Then recently it started doing it again and so I checked my fluid levels everywhere just in cast that might be throwing the warning light and found my dipstick was bone dry.
I am surprised the warning was so general. Why not an oil light? or an oil pressure warning? WHen the master light came on, the screen just said "problem". Kinda vague for such a specific and important matter. My guess is that the oil got so low that the oil pump sucked some air due to the acceleration when cornering or stopping. (negative acceleration).
My question is what would make it start using oil suddenly. True I didn't check it b4 so I have nothing to compare it to, but as we all know, the Prii do not use much oil and if in fact it was so low that it was sucking air 2000 miles after an oil change, they either forgot to add oil or else it started using the 1 qt/ 600 miles that the owners manual tries to tell us is normal. I seriously doubt they shorted me on the last change. BTW I added some oil ....

My '07 started making three very quite beeps while driving, happens about every 15 minutes. It sounds like it might be coming from under the passenger seat. Mileage on vehicle 168000.

My roommate owns a 1987 Toyota Van. Those vans that have the Motor under your butt. Anyways, when we make a sharp turn (like fliiping) in either direction, we start hearing a thumping noise... It goes fast or slow depending on how fast your whipping around. We thought it was a CV joint, but, it looks like there isn't a CV Joint (Axel) Where to start to solve this?? Cause even when it goes down the highway you go into the curve and your really hear it.. The lug Nuts on the van are Tight, I've checked. We may think its a wheel barring..

2005 Gen2 with 216k miles
Driving on highway and accelerated to pass a vehicle, sudden slow down and all warning/error lights went on. Pulled to side of road and used Autel 539 to get codes P0A78 + P0A90. Scan code reader does NOT display the INF codes, so I can not get them.
Turned off vehicle and restarted. Put into drive and it appeared that I could move forward (and reverse) and was apparently running strictly on the ICE - no power coming from the DC motor for assist. HV battery would charge as driving down road.
It was slow moving, but as long as I was accelerating (very sluggish!) was able to move forward. If I took foot off gas pedal then ICE stopped running and would not restart when pressing on gas pedal.

I will try my best to describe the problem:When the car sits for quite a few hours it basically will try to fire up , but can take 4,5,6 seconds before it will actually start. It is a fast turn over just as if your car was going to start normally, but it just takes time. This is not a slow turn over as in a battery problem, or a very cold weather thick oil problem.After the car starts the initial time, you can turn it off and start it and it fires right up.
When I turn the key to the on position, I can hear the Fuel Pump. I have tried doing this a few times in a row, but it doesn't work for the initial start.
This has been going on for about 8 months, and I have basically ignored the problem. The last few starts the same issue persisted except instead of firing up after 4,5,6 seconds it just shuts off. After this I turn the key over and it still fires right up.

My 2010 Prius orange Triangle flashes and beeps when I make a sudden turn or brake. The car works normal otherwise. What could cause this to happen. I only started recently...

I've bought a second handed European Prius 2en Gen from year 2006, the car is wonderful and I simply love it ! I wouldn't change it for anything, but yet I have some problems with it.
When I start the car I get the Red Triangle on the front panel, and exclamation symbol, a VSC symbol and an engine (?) symbol on. On the Display I always have a black bar on the top with a car and an exclamation point on it. Both can be seen int the pictures below....
At this point the car runs normally, the only things I notice are :
1 - When I stop the car (without shutting him down) I notice that the consumption of fuel is at 99.9/L because it is charging the battery, which is already full.
2 - The back-right ventilation fan of the car (on the passenger seat) is ON even when the Air Conditioner is OFF.
After a few miles (I don't know exactly when it happens, sometimes it happens when stopped, sometimes when on the road), the car beeps and then it shows a, on the same black bar on the display, a message saying "Problem", after a few seconds I get a Battery symbol on the right of the car with an exclamation point symbol.
At this point the car starts having the following problems :
1 - The motor begins to speed like if I was at full speed on the highway.
2 - I simply can't do an uphill, the car won't pass the 20Km/h speed, if I gain balance before arriving at the uphill, it will start losing speed until reaching the 18-20Km/h.
At this point I really don't know how to solve this. I only know that, the Toyota Representative here where I live (in Portugal), ask me for 2,975Euros (almost 3,263USD) saying that it is a problem in the Hybrid System. But yet it seems strange because from what I know, if the Hybrid System was compromised, the car wouldn't start at all.
Does changing the 12V Battery on the back would solve this (even knowing that the Display shows a fully charged battery ?) ?

After dining at a restaurant in East Lansing when temp was close to zero F., we found the doors frozen. Not a problem: one yank and they open. Then as soon as we reach 12 mph, instead of the auto lock, the driver's door unlatches and the warning light and beeps come on. Stop. Close door. Continue. Same again. Start, manually lock doors, and at 12 mph driver's door unlatches. And again. Drive home with warning lights and beeps. No problem next day. But curious.

Purchased one owner Prius from Honda dealer May 2014 with 92000 miles.Now 2 months later 94000. Both service departments of Honda and a Toyota dealer said my car handles normally for a Prius.The car dips from left to right while driving at slow and highway speeds. It feels like a boat moving through water. The suspension was said to be good.Driving it feels unstable, like a Montero Sport or a stage coach. I wanted to do a lot of driving this summer, but this feels so uncomfortable.

I first heard this on Car Talk on National Public Radio (sundays at 10, on the west coast). I heard the question but not the answer. Wife favored slow and hubby fast.

I have had my Prius for over a year and this has never happened to me before. Two days ago, about 3 minutes after starting driving, the display switched to a rectangle with BRAKING written in the middle with rapid beeps. This flashed very briefly on the display and nothing else happened. There was no one in front of me at a close distance and the cruise control was not engaged. I discarded it as a fluke.

So I was driving and suddenly three warning lights came on. The Master warning light (Red triangle with !), Check Engine Light and the Hybrid System warning light (Car with !).
My AC works fine and I was able to shut it off and start it back up with no problem. I also did see a difference in driving.

I have a 2006 with 155k miles. I took it into the dealer for a mini service this week. Drove home after the service was complete, then drove to work yesterday. On the way home an alarm sounded and the red triangle light with !, the break system light (O) with !, the VSC light and the engine CHECK light came on.
A friend used his scanner to read the error code for me and it reported a "p0a80" code. What does this code mean? Replace the hybrid battery?

I had a transient warning light appear on my 2008 Prius during a recent drive from the Portland, Oregon area to Seattle . The reason I'm posting this is that this icon isn't listed in the owners manual, nor does it come on when you start up (boot up) the Prius. Also this warning is on the same line as the "ready" and air re circulation icon. On the right side of the display ( the usual low pressure tire, and I think traction control warning icons are on the line below).
This occurred about 135 miles into my drive at the infamous Interstate 5 as you enter Tacoma, Wa ( stop and go traffic) the icon is yellow /Amber a box with 3 yellow squiggle lines which are vertical and cross just past the bottom of the box. After about 15 minutes the warning light went out. It never came back. I have 115k miles and car was recently serviced. I wonder if this is some air flow / ventilation warning. I am overdue to check cabin AF but am unaware there would ce a warning for that. The AC seemed just fine and no effect on the cars performance. Weird.

I was driving my 2006 Prius on the highway (120,000 miles on it). I'd been driving about 10 minutes and all of a sudden, the dash warning lights lit up.
Red triangle with exclamation point.
Yellow circle with exclamation point.
Yello check engine.
The car did NOT lose power. It kept driving fine with no noticeable change in how it operated. Fuel consumption stayed the same. Braking worked fine. I had a completely full tank of gas (had just filled it up before I got on the highway). Temperature outside about around 60 degrees.
I kept driving to my destination (another 20 miles at highway speeds). The car sat parked for about 3 hours. I returned to the car, started it up. The same warning lights appeared, except for the Yellow circle with exclamation point. Plus, this time I noticed on the energy monitor screen the graphic of the red car with the exclamation point.
Again though, everything seemed to be working fine. While the car had been parked for 3 hours I did some browsing through the owner's manual and saw a notation that is the warning lights were only yellow and not red that it was okay to proceed with caution to the nearest dealer.

I can't seem to find my manual, and I'm not sure if I should drive my car home after a warning light came on during my drive to work. It was a yellow exclamation point within a bracket. What this means?
