Prius (2004-09) :: Brake Pedal Seemed To Push Back On Foot - Warning Lights
I drove my 2005 Prius 2 hours and parked it for 5 hours. No problems on the trip down. I got back in it and it started up just fine. I was sitting in the parking lot with my foot on the brake (hadn't moved yet) and the following occurred:
The brake pedal seemed to push back on my foot
The red exclamation point illuminated
The yellow exclamation point illuminated
The ABS light illuminated
The VSC light illuminated
The red parking brake light illuminated (not shown)
All of these lights point to the skid ECU. It seems like my skid ECU is toast or something called the ABS & BA & TRAC & VSC Actuator is an issue (never heard of it but I see it connected to the skid ECU). I did a visual check of what I could and everything seemed in order. I pulled a bunch of fuses and I didn't notice any that were blown. (I didn't pull them all but will tomorrow)
After not finding anything, I drove back home. As expected, I had no regen but the bigger problem was that I had no power assist on the brakes. A few times I actually did skid and the car brakes really bad without regen or power assist. If it was raining or snowing I could definitely see a hazardous situation.
I'm kind of at a loss here. Tomorrow I'll pull the kick panel down and see if the skid ECU is getting power but I can't think of anything else that would cause this situation.
Prius (2004-09) :: 2008 - Constant Beep When Turned Off And Driver Door Is Opened?
Sometimes (but not always!) when I turn my Prius (2008) off and open the driver door, there is a constant beep. There are no interior lights left on. I think whatever I am doing wrong might be draining the 12v battery as it keeps going flat.

I have a 2008 fully loaded Prius.
Keyless entry. it will not lock but pressing the black nubs or via either set keys. It some times beeps or does nothing.
I verified all doors are closed and there is no door open light on the dash. Every time I exit the car the car gives 3 beeps and the key light on the dash flashes.
Prius (Gen 2) :: No Resistance In The Pedal - Brake Turned To Back Out
I was waiting for my son to come out of his work for an hour with the car on. I got distracted reading and messing around on my phone, and since the heater and lights were off, I had no incentive to turn the car off since it was perfectly quiet (the gas motor only kicked on once to keep the battery charged). Then, I can't remember if I turned the car off or left it on while I took a nap for an hour (he was a total of two hours late getting out of work).
At any rate, when he finally came out, I don't remember if I needed to turn the car on, but I do remember that as I pushed the brake down, put it in reverse, and began to back out, I was moving kind of fast and pushing the brake down didn't slow my motion at all. Also, it felt like there was not much resistance in the pedal. I stood on the brake and there was a noise and a jolt as I came to a stop. I really thought I had stopped because I hit something, that's how violent the stop was. But my son walked around the car and found I had not. No dash warning lights came on. I pushed the park button, powered the car off and on, then put it in drive and coasted forward / carefully tested the brakes. All was good.
I put it in reverse and used the brakes without anything seeming out of the ordinary. Then we drove 16 miles home with no issues. Until this incident I have never had a single brake-related issue apart from grabby brakes when it is raining.
This is what I have learned:
When I stood on the brakes, that is the only time the hydraulic system was in play.
Rusty brake components are pretty grabby.
Actuators are expensive and no service center wants to replace them at 92K miles.
Prius (2004-09) :: Beep After Letting Up On Brake
Last week my 2008 Prius started making a faint beep each time I let up on the brake after a stop when I remove my foot off the brake. It also will make this faint beep when I let up on the brake even if the engine is not on. It is faint, nothing as loud as the beeps for seat belts or backup. The Prius is not experiencing any warning lights or any other noticeable problem and is running great.
View 6 RepliesPrius V :: Long Beep After Turning Left
I noticed twice on the commute this morning that my vehicle made a long beep sound after completing a left turn. There were no other warning lights/messages on the dash. The first time, I thought it was something coming through over the radio, so I turned it off, and the sound continued, probably for a total of 6-7 seconds at least. It's similar to the beep that comes on if you start moving and the passenger is not wearing his/her seatbelt. The radio was totally off the rest of the way and it happened at the next left turn I made (when I got off the highway). Although it was icy this morning, it was not particularly slippery at the intersections when I made the turn and I did not notice the TCS coming on, etc.
View 10 RepliesGolf IV / Jetta IV :: 2004 - Brake Pedal Seems To Put Pressure Back When Applying Brakes
So I have a 2004 Jetta 1.8t. Recently I noticed an issue with the brakes. It is a rare occurrence that this issue happens. Maybe 1 out 6 times I slowly stop the brake pedal seems to put pressure back against me applying brake pressure and makes somewhat of a grinding noise and the brakes don't seem to grab as well. But a split second later the brakes return to normal and grab as expected. Could it possibly be air in the brake lines or something totally different?
- Front brakes are in excellent condition.
- Just replaced the driver side front abs sensor and put new rear brakes and rotors on.
Prius (2010-12) :: Long Single Loud Beep
unlike a lot of my fellow prii folks, i love the beeps. My favorite one is the confirmation of locking the doors by touch of handle and also unlocking by touch. Believe it or not i even like the backup beep which is kind of like a nice confirmation of "yo, dude! we are going backwards" but the most important one for me is the long single loud beep. happened the other day when i got out of my car to get a coke and the car emitted a continuous loud shrill beep as i started to walk away. I was still in drive.
View 3 RepliesLexus LS 2007+ :: Less Brake Consistency - Can't Get Constant Pressure On The Pedal
Replaced my rotors and pads and I still do not like the braking feel as I apply constant pressure to the pedal. No matter what I do, I cannot apply even or consistent pressure to pedal and get the car to slow down smoothly or in a linear way. It feels like some power assist component applies varying force to the calipers no mater how slowly or quickly I try to slow the car down. It just isn't smooth like other cars I own. The brake pads grab fine, no warped rotor issues. Does your car brake smoothly from 40 MPH to 0? Is there some power assist unit that may be going out?
View 2 RepliesPrius (2004-09) :: Beep And Warning Message After Brake Recall Fix
10 days ago I bought my '05 Prius to the dealership to get the Brake Recall fix along w/ an oil change and inspection. Since then I took a road trip and put about 1,000 miles on. Two days ago, when pulling up to my house, I got a beep and warning message, since I was home I parked and decided to worry about it later.
The next morning the car turned on but would not move (crawled a bit forward and reverse but was basically dead). I checked the meaning of the warning light and its the Hybrid Systems Warning Light. From the information screen it appears the battery is drained and therefore electric motor won't function.
Of course I'm worried its the expensive battery dying on me but would this happen all at once or slowly over time? Unfortunately I'm at 117,000 mi so the system is out of warranty. My next thought was that something they had with the brake recall may have caused the problem (though it would seem odd it'd take 10 days to happen).
Prius (Gen 3) :: Random Single / Long Beep When Locking Via Handle
Recently, my Prius has been randomly giving me the single, long warning beep when I try to lock it by touching the handle. The car is definitely not still on, and the key is in my pocket when it happens. I've checked the doors, and none are ajar. It's not 100% consistent, but happens about 50-75% of the time. When it happens, I can lock the car with the key or keyfob - but touching the handle just gets me the long beep and no lock.

For the past 2 days my car has started beeping when I open the door after I push the power button to turn it off. It flashed a red lock type symbol in the lower right side of the screen as well. What this is? I can't find out in the online dash indicators. The beep stops when I push the door lock down and shut the door.

I don't know what's going on maybe some body can shed a little light on this. If you hold the brake pedal down for a long period of time you can feel the pedal slowly go to the floor. So no problem I'll change the master cylinder bleed everything brand new fluid. Don't drive it much we let the sister in law drive it we'll I jump back into it the other day to go to Home Depot and once again I notice it still does it. Could the hydra brake booster be bleeding by or what's else could be causing this it's driving me insane. I really can't imagine the hydra booster causing a problem but it's new to me. I was thinking about bleeding the brakes again thinking there maybe there's air but I have run 2 bottles of brake fluid through how much more??

I've had my PIP for a week now My main complaint, so far, is the back-up beep, which of course does nothing for safety but distract the driver. On my 2005 Prius, which I traded for the 2012 PIP, I could go through a [somewhat complicated] procedure to disable the beep, but it doesn't work for the 2012. but any fix one can implement oneself? On general principles, I resist taking it into the dealership for the fix.

The brakes surge with more power when the brake pedal is held at a constant pressure. My guess it has to do with the brake booster. But normally a failing booster would result in less braking ability not more.

View 11 RepliesPrius (2004-09) :: Brake Pedal Really Hard And Car Slowed Way Down
I have a 2008 Prius. Had to do an 'emergency' stop. Put my foot on the brake pedal REAL hard and the car slowed way down, but not down enough. Munched the front end. Now remembering back, I didn't feel any 'chattering' from the ABS brakes. It seems like I got regen braking but never switched to the hydraulic brakes. Is that possible? Did I experience a braking failure? Or do Prius just take a lot longer to stop? I did a test stop in the rental car I have now (not a Prius or hybrid), and it gives me the ABS chatter as I would expect, with a short stopping distance.
View 5 RepliesPrius (Gen 2) :: 2004 - Clicking Sound When Brake Pedal Depressed
I have another small issue with my 2004 Prius. I just noticed yesterday that the second I very lightly depress the brake pedal, a little clicking sound is made down below. It sounds like it might be coming from the brake pedal itself or somewhere underneath the hood. It's only when I depress the pedal slightly and it makes pretty much the same sound when I release the pedal. I just had a 5000 mile service done to the car and there were no issues then.
