Prius (2004-09) :: Brake Light On Occasionally At Startup
May 18, 2011
I have a new-to-me (2 weeks) 2004 Prius, and my wife has noticed a weird behavior on start up which I have not been able to reproduce.
Occasionally when she starts up the car the brake light comes on as if the parking brake were set. The ready light will not be on. No other warning or error lights come on. If she turns off the car, and then turns it on again the light will be off and not return. Tapping or setting and releasing the parking brake has no effect.
She swears it has nothing to do with her pushing the parking brake or not pushing the pedal brake. This seems to have started after I set the parking brake one afternoon, but that could also be coincidental.

I have 2004 Toyota Prius 110k miles on it. New auxilary battery on it. VSC, Brake and Red triangle lights are on. The car wont start. System comes on, but ready light doesn't not appear.
If I discoonect the battery for a minute and connect it back, I am able to start and drive it. After a minute VSC, brake light comes on. I still can drive the car and it drives perfect. As soon as I shut it off, I won't be able to restart it again. I have to disconnect the battery for a minute to get it started. Inverter pump seems to be working fine.
I got the codes with the paper clip VSC 43, Brake 36. After resetting the codes, I drove the car and now it throws VSC 51 code.
Check engine light is not on. When I checked with OBD scanner, it does not show any codes. When we checked with shop's scanner, there was a code smth "LOST COMMUNICATION WITH HYBRID..."

So I had a random issue today. I went to start my car this evening, and it wouldn't start. The lights on the dashboard (warning, maintenance, etc.) lit up, and the headlights and interior lights were extremely dim. Figured it was an issue with the battery. Used my husband's car to run errands and came back about an hour later. We decided to try starting the car again, and it turned on, headlights and interior lights were normal brightness, but the gas gauge is at one bar, which I know isn't possible because I have only put 166 miles on this tank of gas. I reset the gauge at each fill-up so I can track how my mileage changes. The maintenance light is also still flashing. None of these were issues I had last night, so what could be causing all these problems? Can I fix it myself, or do I need to take it into my Toyota dealership?

My parking brake light goes on occasionally. It is the electric park brake. If I engage the brake I can hear the brake engage. Is this a sensor issue or do I just need new rear pads?

I have a 2007 Scion TC. Sometimes the dashboard brake warning light will turn on for a few seconds and then goes off. It happens after the brake is pressed at a traffic light or stop sign, a second or two after releasing the brake pedal and accelerating. The sometime the dashboard brake warning light will switch on for a few seconds. It seems to occur more often when the outside temperature is cold. Also when the car is cold. I had a oil change and lube and they said the brake fluid level was ok.

I have a 2004 Ford Escape that has never caused any issues...except now. I have recently noticed that occasionally when I have my foot on the brake, my car makes a forward jerking motion. It never slips out of gear. It just jerks forward. It's not all the time either. Also this morning, my husband went to start the car and while it was still in park, he said it did the same thing. Like I said, the car never shifts out of gear and I never hear grinding gears when I do shift.

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.

I have a 99 f450 4X4 I'm having brake problems. Without warning when I go to stop my peddle will go right to the floor and I can't stop, at other times I go to stop and the peddle is stiff and I have to put all I have in to it to stop. The abs light comes on and off occasionally at random but as the brake failure has become more and more frequent so has the abs light. Also my steering does seem a bit off, a little tough N jerky and the power steering pump is whining.

Sometimes when I start my car, parking brake light fails to go off. I know this is usually indicative of low brake fluid, but mine is not low. I rarely use the brake so I don't think it's the parking brake switch either as it only happens if the parking brake is not engaged. Never happens on the occasional use of it.
Restarting doesn't seem to work unless I set the brake, restart, then disengage it. Very strange problem. Not a big deal but is a bit perplexing. I never see a CEL or any codes generated at all.

I haven't checked it myself, but a guy told me yesterday that my left brake light is out. I don't see any information in my manual about replacement brake lights.

I had replaced the skid plate module as it was defective with a unit from 2007. The brakes work perfectly but the ABS, VSC ( !) light are on. The codes on the mechanic's computer show non-communication between other modules.

I bought a used 2004 Prius with 121K in June. Noticed recently the passenger side brake light is out. I'm talking about the brake light, with the LEDs, not the rear taillight.

My '07 Prius was running fine until. Pulled into the driveway and shut down then decided to back in some more. Powered ON and ABS and also the BRAKE light came on - car would not shift and the shift indicator & fuel gage started BLINKING. Shut down and repowered with same results.
I've checked the 12 volt supply and it is 12.7, even added a second battery to the engine bay jump start. I used an OBDII reader and get no codes only an E. No improvement .

Occasionally, when I start my 07 I hear a loud zip noise that seems to be coming from the front of the car somewhere. I know it's kinda tough to pinpoint. Something running against the teeth of plastic gears comes to mind.
I should also mention that it happens immediately after the engine has started, about the same time the self leveling headlights start to move.

My engine will occasionally lope at startup. If I look at my scanner the fuel trims will suddenly go negative up to - 20 and then the engine smooths out. It seems to happen in open loop and when in closed loop the fuel trims balance out. I changed my maf sensor, but it did nothing. I don't smell any gas, no Check engine light.

My mother owns a 2004 Toyota Prius, we got the car couple of months ago, and noticed the brake light was out, on the drivers side. Little did we know that it was a hard thing to actually replace, and we didn't bother giving much care to it since we thought it was a regular $15 bulb you just pop onto the tail light.
It turns out, the top part of the brake light attached to the remainder of the tail light does not turn on, while the center and passenger side of the brake lights turn on. It is black colored/tinted, and my guess is this is an LED.

I charged the almost dead 12v with a slow charger and it is fine now. but immediately after charging the brake system light came on. I believe brakes are just fine, and want to reset the light and see if it will ever give again.

I just bought an '07 Prius with all the options except leather, and when I took my wife out to show her how it works, it didn't. The emergency brake light wouldn't go off and the shifter light on the dash would only go to neutral. We turned it off and on again (more than once) and finally the e. brake light went off and the zero showed up for speed and we could go. I'm wondering if there is some safety feature that won't let you engage to go until the e. brake is released. And if the light is on, the car thinks the e. brake is still engaged. Plausible? How do I fix it? Would this be the switch on the pedal?

I have a 2005 Toyota Prius with about 150K miles on it. After work one night i hit a pothole and my ABS and BRAKE lights came on. I took it to a garage and they could t find anything wrong with it so they reset the light. It came back on about a week later (no potholdes this time) and i took it back. They hooked it up again this time it said there was an issue with the computer coding. So i took it to a Toyota dealership. They hooked it up to all their scanners and could find nothing wrong with my vehicle. They recalibrated the sensor and the light went off. Now a week later it is back on again. Brakes work fine and we get no error codes.
