Prius (Gen 4) :: DRCC Emergency Stop At 70 Mph
Jul 26, 2016
I've generally gotten used to trusting the car to maintain distance and slow down autonomously with DRCC. However today I'm not sure I trust it completely.

Prius (Gen 3) :: 2011 DRCC Freezes Locking Onto Car / Hitting Brakes Even While No Vehicle Is Ahead
We’ve been running into a problem with the DRCC on our 2011 Model 5. In simple terms, the DRCC freezes locking onto car in front and activating the beeper/hitting the breaks even when no vehicle is ahead! So far, this has happened once to my wife (when she was making a 90 mile trip)
In all cases this has occurred as the car was passing a semi, when the front of the car was even with the semi drivers door. In one case, there was no car in front, just acted like there was one.
Whenever this occurs, the car continues to brake and the only immediate solution is to turn off the Radar. Also when we re-engage the DRCC, the unit is still frozen – braking for a non existent vehicle.
No problems turning the DRCC off and using the ordinary cruse. What seemed to “clear” the condition was pulling off the Interstate and turning off the car. I also noted that (after it had froze again) that when the ambient temperature had dropped below 90 degrees that the DRCC cleared. The first time my wife ran into this was hot too.
In summary, this has happened only when:
· Passing a semi
· Temperature is high (above 90).
I don’t believe that it is an alignment issue, as I’ve been amazed at how narrow the radar pattern seems to be (and very nicely tracks the steering).
Golf V R32 :: Emergency Stop Light Blinking
This place Michigan is now 28F and raining this morning, so road is very icy. So I was driving about 40mph and tried to stop at traffic light, of course I slid little bit then finally it worked!!!
I tried to play with snow, and tried to apply brake hard to make ABS work, it was low speed like 10~20mph, but emergency light did not blink. I guess the speed have to be more than 30 mph or something.
Prius (Gen 2) :: Unusual Noise When Put On Emergency Brake
My 2007 Prius has started making an unusual sound. At first I thought it was some kind of pump or something, but now???
When I put on the emergency brake, the brake pedal or when I put the car in park or take it out of park and put it in D, it makes a "chuck chuck chuck" sound, not high pitched, but not a low sound either. It seems to be coming from under the hood on the left side. It sounds something like a belt slipping or a pump with a squeak maybe?
It does not appear to make this noise when simply depressing the brake while driving, so I'm not sure it's the same abs actuator issue.

If the hydraulic brakes go out what is the best procedure to brake in a Prius? No, I don't envision this happening just a "what if"?

View 6 RepliesPrius (2004-09) :: Emergency Brake Light Stays On And Car Won't Go
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?
View 6 RepliesPrius (2004-09) :: 2005 - Emergency Brake Light Won't Go Off
From what I've been able to gather there is a proclivity in the 2004-2007 Prii for the emergency brake light switch to break resulting in the dash brake light staying on endlessly. Here is a diagram on page 4 (Powered by Google Docs) of the emergency brake system with the switch labelled and here is a picture of the switch itself (RockAuto Parts Catalog).
I've located my switch and found that one of the plastic side pins is broken off and the whole thing is swiveling around. The problem is that I can't figure out how to get it off so I can replace it with a new one. I don't want to go to the mechanic for something like this.
Also, some of the information I've seen says that I need to replace the entire emergency brake pedal assembly. That could run several hundred dollars and I'm not prepared to do that just so a silly light will go off.

I have a 2005 Prius. Recently the headlight leveling system finally bit the dust. I will get it replaced sometime soon. Meanwhile, I'd like to reset the emergency light on the dash, the triangle with ! inside. As well, I'd like to remove the icon from the display unit. How I might do this?

I have since then taken it to midas to get an oil change and get the codes read.

I bought a car a month back and i just realized a few days ago my front emergency flashers/blinkers do not work. The rear flash fine. the blinker alert on the dash was flashing very fast so I assumed I needed a new fuse. I replaced the fuse today and still no luck.
View 5 RepliesPrius (2010-12) :: Emergency Brake Cable Clanking / Slapping Noise
While the emergency brake was set, I happend to lean against the rear driver side of the the car and was surprised to hear a clanking, slapping noise coming from underneath the rear of the car; seemingly near the left rear wheel. What I think I'm hearing is the emergency brake cable (I assume this is a rear wheel cable brake) slapping against the vehicle frame or wheel axle. Even opening and closing the rear passenger door caused the cable to slap against the car.
This got me to experiment a bit, so I rocked the car back and forth and side to side. It's the side-to-side movement that causes the noise. The emergency brake works when set. The noise disappears when I release the emergency brake.
Prius C :: Multiple Emergency Lights Popped On And Brakes Lost Pressure
Last Tuesday my 2012 Prius C brake system failed while I was driving to work. Multiple emergency lights popped on and the brakes lost pressure. I got it towed to the nearest Toyota dealership. That same Tuesday I was told it would cost $3,200 to fix the brake booster. The car has 114,000 miles on it and I have done regular maintenance throughout.

2010 Prius with 85k miles. Went to start car and here is what I get. All lights on dash come on including emergency icons. When I depress brake to shift into gear lights on dash go dim but not out. Car does not go into gear and neither does it show it going into gear on display. Heater was on and I tried to shut off the fan and again no response. Very difficult to get it to shut off. Pushed off 3 or 4 times and it finally responded. Been cold here in the teens and car has not been used for 3 or 4 days. Everything has been fine up to this point. No problems with anything.

I just bought my 2001 with 153k on it and I notice that sometimes it didn't appear to fully engage in park. What I mean is that.... If I park on a a small incline occasionally after I put it in park and take my foot of the brake..... It will pop into park..... Or I'll have to wiggle a little when I notice the key can't be removed from the ignition. Now that I notice this.... I can make sure it is fully in park each time.
My emergency brake cable doesn't work (and I always do use this religiously on my other cars), and I think having it reduces strain on the transmission..... But darn its near 300 bucks to replace I'm told.
Prius (2004-09) :: 2007 - Keep On Creeping Forward With Emergency Brake Engaged?
I bought a 2007 Prius 2 months ago and I noticed that when I stop at a stop light and engage the parking/emergency brake while keeping it in Drive gear the car creeps forward. I have more experience with manual cars where when you pull the emergency brake it locks the car and prevents it from rolling forward or back despite the car being still in gear, so I'm curious to know whether this is a normal thing with a Prius and pushing the P button in addition to the emergency brake at a stop light with a slight incline is necessary. I find that this two step process of disengaging the E break and putting the car back in Drive makes you slow to take off. But what I want to know if this normal with a Prius?
View 14 RepliesPrius (2001-03) :: Emergency Broadcast System Type Alert Noise When Starting
Been driving my 2002 Prius since January 2005 and I've never heard this noise. It first happened Sunday as I was driving down the road, then this morning (twice) as I started the car. It lasts about 15 seconds for several "rings" of a shrill, electronic (definitely NOT mechanical) sound that reminds me of Emergency Broadcast System tests on the radio, or a really annoying cell phone ring. No visual warnings or lights are displayed (well, the Check Engine light is on, but it's always on, and my local Toyota dealership has been unable to shed any light).

Let my brother borrow my 98 S-10 and before he even got home with it he called and said the brake light was on. I figured it was the emergency pedal was down a little. Said there were no leaks. Got it back today and the fluid level is way down. Filled, but the low pedal is still there. Can find no leaks. Also the ck engine light is on. May not be related. Didn't get a chance to ck code.
View 14 RepliesGolf/GTI VI :: Emergency Brake Getting Stuck?
Okay let me start by saying my car is APR Stage 1. The other day I was driving with my cruise control on and held in the accelerate button to speed up. After holding in the button for a couple seconds the check engine light and battery light flashed back and forth as if I changed some setting with the tune. Ever since that happened, if I turn the TCS off, the emergency brake light comes out and the error message 'check brake pads' is displayed on the MFI. Also, the weird part is that it's not just the light. The actual emergency brake is slightly on without pulling the handle. I can feel it when I accelerate. It's harder to get the car going. Once I turn the car off and leave it off for a few hours it goes back to normal. Why this is happening?
