Avalon 2005-12 :: Master Warning Light Coming On Occasionally When Braking
Feb 20, 2013
2007 Gen 111, with 148000 miles. Recently I notice the master warning light coming on occasionally when I am braking. I do not have to be braking hard but it seems to show up more often with the engine brake on. Read out on the top of the screen reads "Problem". I am not finding much of anything in the book on this. It did this for a few times a few thousand miles ago and then did not do it for awhile and now it does it again occasionally, but more often. IF it gets bad I'll take it in but otherwise I figure on waiting until the 150K maintenance.

It has now come on 3 separate occasions, a week or more apart. Each time the yellow brake or tire light comes on. The next few times they come on together at start up. Then the triangle by itself comes on, does not clear. First time I was driving up hill. Second time I had just hit a drive way riser (not jarring). Today I was driving on a straight level highway and it came on at around 55 MPH.
Battery had been replaced after first instance. The inverter valve replaced too. Now what? It drives normally. Though it is the yellow brake light that accompanies the triangle Toyota says that codes say battery problems.

In my one-owner purchased-new 2005 Prius w/ 74K miles and w/ no maintenance/accident history other than doing all scheduled maintenances at Toyota Dealers along w/ recalls applicable at each time (other than we had Toyota replace the 12V battery last year just because I knew it would die at some point anyway and I don't like pushing my luck; I'm not 100% certain if there's been a recall on any water pump for this car and if so, don't believe the dealer has mentioned it), I have the following indicators which appeared all at once while I was driving along at around 45 MPH in no unusual circumstances (80F, dry afternoon, about 30 minutes into a trip of mixed speeds, no loads in the vehicle, no effect on the car while driving):
From Left to Right on the display:
1) Red Triangle - Master Warning Light
2) Orange (Symbol)CHECK - Malfunction Indicator Lamp
3) Orange (!) - Brake Warning Light (but it didn't highlight the word 'Brake' in red)
4) Orange VSC - Vehicle Stability Control Warning Light
On the Screen:
Orange Car w/ the ! symbol - Hybrid System Warning Light
We immediately aimed for the house (about 5 miles away); the car drove perfectly fine, with the engine stopping and starting at lights as needed, with speeds going from the 55MPH we were traveling at the time of the alarms down to 0 and back up thru 35/45 MPH and such per normal off-interstate driving. The battery currently shows all the blue bars, and the engine and hybrid systems showed charge/discharge as usual as we drove. There was no discernible change in the driving reaction of the car to brake, steering, accelerator, etc.

for the last three days, I had the big red master warning light come up four times during normal braking, also "Problem" was displayed on the LCD where "Add fuel" is displayed when fuel is low. But no error code showed on the OBD reader. I searched found that it might be related to 12V battery which I replaced two years ago.
2008 with 120K miles.

I have a 2011 Avalon Limited, and recently the VSC warning light came on (and is still on). Following some of the advice on accessing codes (like jumping ports on the OBD2 plug) I ended up getting codes that said my #7 cylinder had intake issues. Funny...I don't recall seeing a V8 under my hood.
I am hesitant to take the car to the local Toyota mega-dealership because of the excessive amount wanted to simply read the codes. How I might either access codes for the 2011 or even how to clear the light in order to see if it returns or not.

I had my tires rotated. About a month after that my tire pressure warning light came on. All tires were perfect expect the rear drivers side needed about 6 pounds of air pressure added. Now all tires are at 32PSI per owners manual recommendation.
The problem is that the tire pressure warning light stays on permanently. I read the owners manual and pressed the button under the steering wheel and the tire pressure light blinked 3 times like it's supposed to during a reset. However......the tire pressure warning light still stays on permanently. It won't go out. I followed the instructions in the manual. Maybe I did something wrong but I don't think so.

I had my ABS and Traction Control system checked a few times for buzzing sounds and ABS warning light coming on occasionally. My mechanic assured my all the speed sensors and connections were good. I recently noticed there was uneven tire wear on the right front tire. Could a severe misalignment of the front wheels cause the ABS warning light to come on?

My 2006 prius has the Master warning light(red) and the braking system light (Yellow) on while I am driving, and I went to the dealer.
The technician told me that he could not verify any warning lights ON at that moment, and he performed health and diagnostic checks on it. He inspected connection at auxiliary battery and junction box 1. All checked OK at this time. No repairs recommended at this time.
However, the master warning light came on when I pick up the vehicle. The dealer told me that they will inspect it again tomorrow. And they found that there a P0A08 error code. They suggested me to replace the hybrid converter/inverter.. My car can still drive while the lights ON.

I know the manual says the tank's cap. is 18, but I've run the gauge to ' E ' with yellow warning lite on and it'll still only take 15 -15.5.
Can it still have 2 gal. past the E marker ?

During a trip South last summer my A/C would -occasionally, after hours & hours of running- begin to pump out hot air.
Not warm, muggy, outside air, but HOT air. Then, if you shut it off for a few minutes, you can turn it back on & it works normally.
I forgot all about it, since it only happened twice, once late at night, once midday.
Today, a friend, who was on that trip said he came across a something in newspaper about a fix for this, but now can't find it.

I occasionally hear a buzzing sound in my driver side door. I turn down the radio to make sure it wasn't the speaker. This noise only last for a few seconds then goes away.

I know that if the shifter/transmission is set to "S" then it tends to use the engine as a braking system sort of like a manual transmission. My problem is that it does this while in "D" (drive) for about 5 seconds and then it back to normal as in it's like it's put back into neutral. I read the manual and it states that when you place it in "S" mode and then back to "D" mode it retains some of the "S" features such as engine braking, but in our 09 Avalon XLS, it does this all the time while in "D".
Question: Is this normal for engine braking for about 5 seconds while in drive mode?
If so is there any way to get it back to a normal automatic drive mode where as when you release the gas pedal it coasts without engine braking?

I ask because my father's 08 Avalon is pulsing during braking at highway speeds but only sometimes. When it does it we can feel it in the steering wheel. I suspected maybe one of the caliper pins was seizing. So I pulled the front wheels. The pads and rotors look great. I removed the pins, cleaned and greased them. On the test drive it pulsed two times for me but was totally smooth on the rest of the drive.

I have an '09 Avalon with 34K miles. On braking we get a shudder. It's especially noticeable on gentle braking. I am pretty sure this is due to the brake rotors being warped or whatever the correct term is. Are these covered under warranty? I'm a skeptic and I feel sure the dealer will try and blame the tires but they are wearing evenly and are rotated every 5K. The ride is smooth when not braking so tire balance should not be an issue.

We recently purchased a used 2006 Prius. The vehicle has approximately 74K on it now. Well the other day my wife went to leave work and pressed the power button while pressing the brake pedal, and the Master Warning Light and brake warning light both came on. The car would not allow her to shift the car so she tried to turn it off and it wouldn't do that either. After about 5 minutes she finally got the car to turn off, and when she restarted the sequence everything went back to normal and she drove home fine.
We called 2 dealers and they both seem to be confused by the symptoms, but one thought that maybe the battery was old on the transmitter. So thinking that might make sense I replaced the battery with a new one.

My wife and I own a 2006 Toyota Prius that we bought used 2 years ago. a couple of days ago, the master warning light (red triangle exclamation point) and check engine light came on. I took it into the dealer and of course, our hybrid battery was dead - battery and a new ECU required.
Our car is at 99,000 and 32 days out of warranty. Went down the road to atlanta hybrid repair. they were incredibly nice, and said that my computer was fine, but the battery would need to be replaced.

I was driving earlier today and it flashed twice (about a second and a half each), and then didn't see it again for a few hours. I was going about 40 MPH at the time.
I was driving somewhere else today and when I got to the 70MPH mark (really, between 60-70), it objectively increased in frequency. I searched google and these forums, and the closest thread I can find that shares my ailments was this one:

So the other day my girlfriend got in her car and it had the master warning light on. we took it to the dealer and now they are saying it is something with the transmission and it would be cheaper to just install a new one. Another thing is how could it be the transmission if i drove it over to the dealer and head no problem with the gears changing, but he also said something about a voltage leak.

When I start my car the master warning light comes on with all the other lights and then goes off with the other lights. It does not come back on while driving and there is no warning sound with it. This just start happening. It never came on with other lights when first starting it up. I have a 2009 Prius.
