Lexus RX 2010-15 :: ABS / Master Lights And Audible Warning Activated Suddenly
Mar 31, 2015
We were driving 2015 450h with 2200 miles on a slight downhill grade about 50 mph. Suddenly ABS warning light, master warning light, and audible warning activated. The center console "Brake" illuminated and the information center displayed "check hybrid system".
My wife attempted to pull the car off the road in a controlled manner but even slightly touching the brakes caused them to pulse, braking hard and then releasing. She finally got the car to the side of the road and shut the engine off. I then got into the drivers seat and turned the car on. The messages remained. Tried on an off, still the same. Tried brakes, the seemed functional. Since we were in a location that did not have cell service and it was an unsafe location to leave the car managed to drive it into nearest town.
Turned the car on and off about 10 times over the period of an hour. Without explanation, the car started with no warning messages. Dove the car another 200 miles since and it has now been at he dealer for over a day with no word.
I did see where a few RX350 models had reported a similar problem, but no 450h's. At the time of the incident we were not using the PCS system (off) . I am wondering about that as well since the ABS might be tied into the PCS?

I drive my 2005 Prius 40+ miles each way for my commute. I bought it in the fall of 2007 with 56k miles already on it, and with my commute I'm up to 140,000 miles already.
This morning I was about 5 minutes from work, cruise control on, and deeply absorbed in listening to a podcast. I was startled out of my reverie by several things happening simultaneously. The car beeped, the cruise control kicked off, and multiple warning lights lit up on the dash, with a warning icon of some kind also on my MFD.
(Once stopped, I looked up the warning lights. They were: Master warning light; Check engine light, or "malfunction indicator lamp", according to the manual; YELLOW Brake system warning; VSC warning light. On the MFD, the Hybrid System Warning Light was on.)
I was on the highway doing about 70 and I had just crested a hill, so I allowed the car to coast on the downside while trying to access the situation. I cautiously pressed the accelerator, and though the road noise made it impossible to hear the engine, the car seemed to still be driving normally. The Energy Monitor still showed normal flows between battery, engine, and wheels. I had one final, short uphill climb before my freeway exit, so I chanced it. I took it easy and allowed my speed to decrease on the uphill so as not to push too hard, just in case. Once off the freeway, most of the remaining mile is downhill or flat - I can often make it to the office without the engine, and in fact I did so this morning.
Once at the office, I put the car into Park and grabbed the manual so I could identify all the warning lights before powering off the car. I turned off the Prius, let it sit for 5-10 seconds, and powered it back on. The brake system warning and VSC lights did not come back on - only the master warning light, and "check engine" lights reappeared, and "Problem" on the MFD was again replaced by the Hybrid System Warning icon. After the usual 10 seconds, the engine started normally and responded to the accelerator.
One additional note: After the freeway exit, my car is usually at 1 green bar or just below on the hybrid battery. Immediately following the freeway exit is a steep downhill that usually puts the SOC to completely full. That was the case again today, and as often happens, that full charge was able to take me the rest of the relatively flat, distance to the office at my usual 25-35 mph. I mention this because whatever might be setting off the warnings, the Prius still seems to be managing the charge level normally; at least in the admittedly short period I was able to observe it after this occurred.

I have experienced a strange error 3 times now in the last few weeks. It appears that one or both of the headlights go out for a second or two; this if followed by a audible "beep" and a warning indication flashes over the center dash screen that states "check lights" or similar. A second or two later the front light(s) are back on. The warning is orange or yellow in color. My Phaeton has just over 37k miles.

I was changing the interior lights for my wife's 2010 RX350 and suddenly all the lights went out on me at the same time. Did the fuse in the box went out on me? I just did the same for my Isf and everything went well....

I have a 2010 prius. I bought the car used a month ago. at the time of purchase both parking lights were on when my headlight is turned on. Now it won't turn on unless I turn on my high beam. Should I take it to Toyota dealer and have them take a look at it. It is certified preowned.

Title says it all. Occasionally when I try to start my 2007 Prius (70k miles), the master warning light along with the brake, ABS, and VSC warning lights all come on. I'll turn my car off and then turn it back on and it will start right away.
One thing that I notice is that it seems like the headlights and/or the MFD is dimmer than usual when this happens. I'll turn off the headlights, turn on the car, wait for it to start, and then turn on the headlights and everything will work correctly.

I was diving on the interstate and these lights came on and the car beeped. I checked the tire pressures and now the car will do nothing. It says a problem with park.

Apparently my 2008 Prius decided to tell me in it's own way the same thing by showing me these lights this morning.
So they turned on while in a drive through, around the corner from my house. All except the master warning light. 5 minutes after the initial ones, the master light came on. And the braking power disappeared. I immediately got it home and shut it off..
After some research, I performed the 12V Aux battery test on screen in the car.
Confirmed -11.8v while ON, and 11.4 V when in ACCESSORY mode. So the 12v battery more than likely is the culprit for this problem.

I was driving down the highway today and the brakes light (!), vsc, and master red triangle warning lights came on, along with a car with an ! in it on the main display screen. There is no noticeable difference in noise, mpg, or breaking performance. From reading through previous forums a bad 12v battery seems to be a common problem. Mine was replaced ~8 months ago. About 2 weeks ago the serpentine belt snapped and the car was drove ~2 miles to my home where I replaced it along with the bad water pump and also the thermostat. Could that have caused my current problem. 130k miles on the car...

My case involves a 2005 Prius with 55k miles on it with the problem of the master warning light (triangle with !), yellow brake light ( (!) ), airbag, and VSC lights coming on whilst driving. The car drives just perfectly fine without any discernible problems. Scan tool did not detect any codes. Tested the 12v auxiliary battery and it is strong with both voltage and amperage (even went as far as temporarily jury-rigging a fresh v12 battery in parallel with it to see if it would alleviate the problem). Inverter coolant pump runs well, coolant changed with appropriate Toyota Super Long Life coolant (50/50 mix) and system bled. Despite some drivers' concerns over disconnecting the 12v battery to reset the lights, this was done and the lights would go out, only to have them come on again after about 5-10 minutes of driving. Asides from the lights coming up, the car itself seems to be asymptomatic. Hybrid system appears to be running smooth and fine, SOC is good, asides from the lights the car drives very well.

I bought this prius and it runs and drives great, no issues until a couple weeks into ownership and the car refused to "ready" up. i figured out real quick it was the 12v battery....BUT instead of replacing it i was trying to be cheap and charged it to verify for sure, worked great for about a week until it wouldn't start the car again and gave me the "park on level ground" warning. i got passed it after a few presses of the start button but the master warning, VSC, Brake (!), and airbag lights came on. I replaced the 12v promptly and this did not remove the lights. 2 weeks later the lights are still there and I have tried resetting the brake/airbag lights via pins 4 and 13 and failed at getting the lights to go out. a scan tool will delete them for about 10 seconds.
The codes I was able to pull via blink were:
(!) 11
ABS 42
VSC 51 45
airbag 23
I cleared them with the "press brakes 8 times" method, lights remain and codes pop up
VSC 51
airbag 55 57 23

I got a 2010 Prius. I noticed that when I turn the car OFF , the master warning sign (yellow triangle with an exclamation mark) and a message in Japanese (which I cannot read) appear for a few seconds. I don't see the warning when switching the car ON, or while driving. I experienced this frequently when switching the power OFF. Why this happens?

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.

Vehicle: 2009 Toyota Prius Base ... Recently my car started showing the master warning light along with the temp warning light on the navigation screen. After opening the hood and inspecting, there is a coolant leaking from somewhere. Took it to the dealer and was told there is no leak but a bad/blocked coolant tank assembly. Question is, if I bought the tank myself for under $1k, could I replace it myself? What would be involved besides replacing coolant? Do I need to get the air out of the lines? Etc.

Bought a 2010 lexus rx450h with 45k miles. Last night on my way back to home suddenly its front lights went off without any warning. Instrument panel was illuminated but no lights even the indicators and head light dippers , front fog tights were not working. Few buttons on panel like tail gate, height control were also not illuminated.
I stopped the car and after 10-15 minutes of fiddling around. Switched on and off the car a couple of times. Its lights came back. Now im a bit worried what caused this sudden black out. What should i check so as to get this thing not happening again.

All my dashboard warning lights are on in my car and won't turn off ( as shown in pix ) every time I start my car. I wonder what's wrong with my car ?

The last few days I have noticed that after starting my car my master warning light appears for about 15 seconds and the disappears. Seems to stay illuminated longer than normal. Few questions....
Does the master warning light illuminate every time the car starts?
Does the warning light stay indicated for a while before going off or should it appear and disappear within a few seconds?

The other day I backed out of my garage and didn't notice that the parking brake was still engaged. The car rolled out without a problem.
Only when I put it in drive did I realize that the parking brake was on, since the car didn't roll forward. I also got an audible alarm.

Yesterday the brake warning light came on in my 13 350. I checked, and the fluid level in the master cylinder was at the "min" line. I don't think I've ever had to had brake fluid in any car before. Seems to be Ok today, but I was wondering if other folks have had this happen? Of course if it happens again I'll have to check the brake system. Just wanted to check.

I have a 2003 Toyota Prius with ~250,000 miles. Yesterday I was driving and the vehicle started to "stutter" and the warning lights came on. My ScanGauge indicated code P3125. I drove normally for 2-3 miles and parked for a bit. When I returned, I was able to start up and drive home with no problems (about 20 miles of highway and stop & go traffic), and drove most of this morning, but around noon it happened again and this time the vehicle would hardly move at all. It had no reverse and I had to push it out of the parking spot. I managed to limp home and park it.

I own a 2004 Prius with about 122000 miles. Today I was driving up a steep gravel driveway, going very slowly and slipping a little. The VSC light was blinking and then the car came to a stop. At that time, the big red warning light came and check engine light came on along with a message on the info screen reading "Problem". AND most distrurbing of all, a pinkish car symbol warning with an exclamation mark through it that the manual tells me to take it to the dealer immediately.
