Prius (2004-09) :: Beeping With No Indicator Lights During Startup And After Driving For A While
Dec 15, 2014
I've been having an on going issue where my Pirus will start beeping but there is no indicator light I can see showing any kind of issue. It will start beeping during startup and after driving for a while, no exact time something like after 25~30 mins. It sounds like the seatbelt beep but louder and both will beep when my wife does not have hers on.
I replaced the Aux battery(was old needed to anyway) with a yellow top but that didn't fix it. And again there is no indicator on the dash or display showing issues no red or orange triangles. Checked the prius's diagnostics but no codes appear under the diagnosis check I or II, sycheck mode or LAN monitor.

I have a 2007 Prius 5 with 205,000 miles. Just recently, while Im driving the Red Triangle blinks on intermittently along with an annoying beeping. I took to dealer and they diagnosed error code C1300 which indicated that I needed a new "Brake actuator assembly with skid control ECU". I declined price tag because they said it's nothing critical (despite that it sounds rather important), and car will run fine without replacing this part. However, they said "nothing we can do about the intermittent red triangle and beeping".
Is this true? It's a very annoying noise. I know that it is possible to turn off the reverse beeping. Isn't there a fuse associated with "beeping" that could simply be disconnected?

Have been driving my Prius with no issue all week. I leave the car home and take my wife's vehicle, while she drives it today without incident. I come home and hear the car making some strange beeping noise (NOT the anti-theft alarm, different). I hop into the car and try to start it, and the check engine and ABS lights come on for a second before other lights in the speedometer area kinda half come on. The gear indicator comes on and has boxes blinking on all of the letters.
The MFD never comes on.
It appears to be the 12V battery dying. The car has 150k miles and I have never replaced the battery, so it seems I was way overdue for this.

My 5 month old 2015 Prius develops a problem. Once in a while when driving at night, the door open indicator and dome lights will come on for a moment and off right away. I assume it is cause by a loose connection or faulty sensor. Before I take the car to the dealer, is there something I can check?

When ever I park my 2001 Toyota Prius for a long time in a sunny weather it gets hot inside and outside. When I want to start the car all the front panel lights and alarms will go ON. I still can drive the car without any problem. I could not get any code with the OBD2 sensor. All I can do is to delete the code. Again it just happens when the weather is HOT.

I was on the highway yesterday when the red triangle went off and the screen said Problem. I babied my 2008 Prius to the dealer. They said the 12v battery was bad. I should have just gotten the yellow top in last week like I wanted but oh well. Here is the problem, today it did it again. It first happened at 70 mph but today it did it first at 15 mph then pretty much stayed on until I did not accelerate for a while. No noticeable performance issues, just the warning indicator. I did notice the noises after shutdown are sounding different than before last week. I also put a code reader on it both without running and on a test drive and no codes showed. What is going on?
More info: Just hit 100,250 miles. Purchased on March 17, 2008. Went in last week before the 100,000 miles for a check up and ended up with $1,000 for a coolant pump (both now, other coolant pump was replaced within the last 6 months). Also got: break fluid, belt, break alignment, oil change, tires (this I was expecting hardly passed state inspection in March), possibly something else.
I have been doing the oil changes since 15,000 miles, filters, pcv (or pvc whichever), all normal items. Problem free until I have them do a check now issues. So to recap non normal items done: blower motor in 2009, radio replacement in 2008, coolant pump in Mayish, other coolant pump and 12 v battery last week. Read more : [URL] ....

I have a 2006 Toyota Prius and it won't start after it was detailed. No engine detail. The key will still lock and unlock the car and when I press the power button sometimes nothing happens and sometimes multiple indicator lights go on and off. The battery is not dead but it may be low and the car was working perfectly before it was detailed. The doors were left open for some time and I'm sure buttons were inadvertently pressed during the cleaning. I tried to jump start but no luck. Is there a way to reboot the system or a way I could troubleshoot before we tow it to the dealer?

..few days later having some problems: red triangle, vsc, car with exclamation point. Took the car to toyota and scan came back with codes p0a08 and p0a09. Toyota diagnoses as needing a new inverter converter. However, the indicator lights are very intermittent and the car shows no real symptoms. I should mention the HV battery and 12v battery are brand new. Does this seem right needing a new inverter converter? Could it be something more simple like wiring/harness to converter?

I was driving 71-72 on an interstate with a 70 mph limit. In the distance, on a bridge I saw a bunch of police cars. Suddenly the Prius started beeping. No alarms went off on the MFD.
Within seconds of the Prius beeping, I saw a cop crouched on the side of the highway pointing his radar gun right at the car. As soon as I passed the cop, the beeping stopped.

I bought carpet and loaded it into the PIP, needing to strap down the hatchback with the carpet sticking out.
As soon as I drove off both turn signals started flashing and a tone beeping.
The flashers stopped after a minute, but the beeping sounded all the way home.Very Annoying.

My 2006 prius started beeping and showing multiple warning lights - The big triangle with the exlamation, Brake System Warning light and Check Engine light on the dashboard. On the main screen the hybrid system warning icon popped up.
I asked from a toyota service place and they said this might be due to multiple reasons (they didn't mention exact reasons) and will cost a lot of money. I've been checking some posts and found some advice regarding the inverter cooler. I checked the coolant container for "waves" as instructed by this post Suddenly hit with multiple warning lights! | PriusChat.
I can see the coolant moving when I turn the car on. What other reasons that can cause this issue?

I drive a 2000 VW Golf with 148K miles on it. One Saturday this summer my brake indicator light started lighting and beeping intermittently as I was driving. My brakes were operating fine so I did not read my owners manual until I reached my home. It indicated that I needed to have a qualified mechanic check it immediately but as it was almost 4 o'clock in the afternoon I couldn't find a mechanic in any gas station or garage. As I had a 200 mile drive to do the next day, I purchased brake fluid and carefully followed all of the directions for checking and filling my brake fluid.
However, when I took the cap off of the reservoir, the reservoir really looked fine and I was only able to add about a teaspoon max of brake fluid. However, when I tried driving the car, it seemed that the problem was solved as the brake indicator light did not come on again. Approximately 3 months later now the brake indicator light is intermittently going on again: about every other day. It goes on and then shortly after it goes off and then it doesn't come on again for a day or two.
Inasmuch as I added such a small amount of brake fluid last time I'm really not sure that the problem is actually with the fluid. I wondered if perhaps it was more of a vacuum problem or that by opening the reservoir some air escaped or something of that nature. I also wonder if possibly there's a component that's giving a false reading. At any rate, I'm a little white-haired old lady and there's a limit to what I can do on my car myself and I'm also a target whenever I go into a shop to get the most expensive diagnosis and fix. I'd like to go in to a shop with good information so that it doesn't become an expensive fishing expedition. What could be causing this?

My 2014 GX has been great except for one annoying problem; with BSM mode enabled, the passenger side BSM indicator randomly lights solid when driving down the road with NO vehicles around me (driver side indicator works perfectly 100% of the time). Does not appear to be correlated to temperature, day/night, humidity, speed, or conditions mentioned in the manual. Other current RX and GX owners I know don't seem to have the issue.
Can the BSM system be calibrated or is the detection program burned into the individual sensors and control module such that the system cannot be re-calibrated? Does a GX BSM system publication exist? I have several photos illustrating the problem. Reported to dealer. The dealers conversation with Lexus was that it is not a perfect system with no explanation as to why one side would have the issue but the other wouldn't. Below is the online reference that Lexus provides. The BSM feature is a very nice one except for this intermittent issue.

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.

2007 Prius 215,000 miles. Car has been a champ for the almost 2 years I've owned it, buying it with 150K miles. No real troubles and I've been driving it constantly as you can tell. Had an extended warranty repair done back in the winter when dash lights went out completely yet car would still start & run. Replaced 12V battery back them trying to diagnose trouble and it was original battery anyway. Daughter was driving when almost all dash lights came on including the red triangle. She came back home, turned it off. Next start was just red triangle and check engine light with red car on center display. Now it's just the check engine light and red car after sitting for an hour. I plan to take it in to get check engine light checked out.

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.

Last week I was told I needed a new engine battery because of low voltage. Later that day I put the car in reverse and it started beeping. I thought something was wrong because the battery that I've had since October 2008 didn't do that. I took my car back to the dealer to have it checked. The technician said that he couldn't change the setting. I also had 3 recalls fixed the day the battery was replaced.
What about the beeping when in reverse. Why didn't it do that with my original battery and why is it doing it now? Or could it be something else?
