Prius (2004-09) :: Electronic Brake System Inoperative When Car Parked In Mud
Mar 22, 2015
Yesterday there was a huge rain. Our 2009 Prius couldn't park under the carport (on slab) as we would have had to drive a ways through really soft water-logged ground in front of it. So the wife left it parked on our circle drive driveway, which stays harder than the ground elsewhere, as there is still some caliche left on it. So an inch or so of mud was on all the tires and even more mud on wheel wells. We are on a slope, so I am sure that water never got up to the underside of the car.
Today I go to drive it---fortunately it was not stuck---but have the sonalert tone going off, the red brake warning light on, the ABS light on, and the VSC light on! I was hoping it was just an accumulation of mud blocking a wheel sensor, so I took it to the car wash and washed the inside (primarily) and outside of the wheels off. Then realized that mud is non-ferrous,so it shouldn't block a wheel sensor signal anyway.
I do have an OBDII code reader.....might it be able to read brake system trouble codes on Prius? This surely is induced by mud or moisture.....what would it likely be? It has always been perfect as far as brakes until yesterday, when it got a huge amt. of mud on tires. Could maybe water accumulate in one of the sensor harnesses, effectively shorting it out?

I parked my car (outside) and went on a business trip for three weeks. When I came back last week, when I turned the car on, the brake light and the ABS light were on. And it hasn't turned off since.
The car was working fine and didn't show any sign of troubles prior to me parking it, no funky light was on. What could be the cause? It wasn't driven during three weeks. What could have deteriorated to cause these lights to come on? The car seems to be braking fine.
FYI, before getting to my car last week, after leaving parked for three weeks, I mistakenly pressed the Panic button. And I didn't realize that the Panic button got stuck and was continuously in circuit. And it stayed like this for an hour before I realized what happened and fixed it. Not that I think that it can have an influence on my current problem, but thought I would mention it anyway...

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.

2008 Prius touring model, owned since Dec 212. Brake system warning light went on when our rainy season started and went off briefly, but is now on all the time.

When I park, the climate system adjusts to send air down to the foot wells. The climate system keeps the air running long enough to drain the left side battery. I replaced both batteries two days ago. This morning my, brand new, left battery was dead again. The first two weeks I owned the car I never noticed the climate staying on, only the last 6 days.

My wife's 04 GX deflates sometimes when we park it, you can clearly hear a loud "whooshing" noise occasionally when we park it in our garage. The rear then goes to the lowest possible setting, it looks odd laying that low. Because it's not my car, I don't know if it always did that, but it seems "new" to me.
The deflation sound is coming from the rear mounted compressor on the rear driver side, I went under the car to investigate. It also appears that the air bags themselves aren't leaking, I raised the car to the highest setting, and it stayed there without the compressor kicking on or any leaking noise.
My guess is maybe the sensors need to be replaced, the thing is, I don't want to "shotgun" parts at a problem and spend $500 or so dollars on new sensors to experiment. How do I know the rear is behaving correctly?

2004 prius. I change the brakes on various cars all the time, and never had this problem. After I changed both sides, I started the car, and saw 4 lights:
- Red brake light
- The yellow exclamation light
- ABS light
- VSC light
The car now stops funny, and reading the service manual, it says that if there's a failure detected, that it will revert back to very basic braking (no abs, only fronts, etc..)... As I was exiting off the fwy, I realized this when one of my front wheels locked up, even and I was not stopping very well. Scared the crap out of me.
In any case, I can't see what I may have done which would cause a failure. The only thing I could think of is to bleed the brakes again, but I did this and think it's ok. Is there anything else I can check or is this something I have to get serviced? I saw another thread where they suspected the actuator, but it is somewhat a coincidence that it would go bad after I replace the pads? I'm not sure how the regenerative brakes works on a prius, and whether there's anything I could visually inspect to see if I bumped something???

My steering wheel controls on the lower half quit working last year , then the cruise control quit intermittently last month , then the air bag light starts appearing last week. Deciding this means a failed clock spring / spiral cable , I took apart my spiral cable housing, and found two obvious breaks in the electrical wiring . I first bought a salvage unit on Ebay, to find it arrived bound, didn't turn freely (and no returns from seller). I then bought one from the dealer and installed it last week and very happily have all symptoms fixed!
The replacement was easier than I expected, the steering wheel was not actually very tight, I doubt I needed the steering wheel puller I 'borrowed' from the parts store , could have just loosed the main nut, wiggled and tugged it loose. Just a note be sure to remove 12 volt power from the car, and mark the steering wheel center shaft to the steering wheel for reinstall .
As a rural mail carrier I deliver mail out of my prius with the window down, traveling about 5 hours a day on dusty ,sand roads in Kansas. The car interior gets dusty and this caused the failure of the spiral cable.
Pic's of the old failed unit, the new one comes with some lubricant, white perhaps lithium grease for the ribbons/ wheels, mine had dryed up patches of grease, some I cleaned off the ribbons before the pictures where taken. I'll check the new one in a year, may regrease , cleaning it out to try to prevent this from happening again. I did add some plastic under the airbag to improvise a dust shield for the new spiral cable. Car has 197k bought it with 106k , now has around 60 k from driving on the route.

I have a 2006 prius I got used and in good condition about 3-4 years ago. I never had any problems until a cop pulled me over and it turned out my parents had decided not to notify me they hadn't renewed my registration and my insurance they've been paying had ran out. I've since learned my lesson on keeping up with the dates.
I "luckily" got to go home with just some tickets. It sat about 2-3 months until I could get the money to line everything out. I ran it at least once a week but apparently that wasn't enough? Now that everything's up to date I started driving it and the yellow circle with the (!) in it is on. The Master system light, the check malfunction light, and the hybrid system light is on.
It seems like it applies the brake when I'm driving constantly now. It stalls when I first try to speed up. And the fan? on the passenger side of the back seat is always running for some reason. I tested my battery volt and it's at 9.2.
I took it to an auto shop today in town. I live in WV in the backwoods. And they wouldn't hook it up to check for codes and referred me to a dealer about 30 min. away... I've never had any problems with this car before.

The brake lights do now work when braking but the 3rd (rear window) light works and tail light filament of both bulbs are ok. So the brake light switch works. right?

Back in March I started a thread regarding my 04 Santa Fe 3.5 which would not start after a spark plug change.
After a ton of research, & a smoke test on the intake I came to the conclusion that there was an issue with the throttle sensor as I unknowingly opened it when I was removing the intake to get to the last bolts behind the manifold. Shortly after my post, I decided to bite the bullet & buy a junkyard TB out of another Santa Fe 3.5.
After installing the new TB, the car now starts but runs extremely rich. I am now getting the code p2135 for Electronic Throttle Control System Malfunction.
Luckily up until this point I haven't needed the Santa Fe as it is mainly a winter vehicle. However, winter is quickly approaching & I would like to have her running before the snow starts to fly.

I recently discovered a squeak when the car is parked and I move the car forward and backwards. The harder I push, the more it squeaks. I went to a mechanic who told me the struts were "bad" and needed replacement.

2006 VW Passat VR6 4Motion - started the car and the electronic brake light was on. Pressed to release it it would not release. Pulled the key out and started and turned off the car several times still nothing. Tried it again and it released the electronic brake lights. Is it something I should worry about. By the way called the friendly local VW dealership when I got the "release electronic brake manually" and none of their techs know how or if that could be done.

I just had my 90K service done, drove my '04 prius home and parked it for 2 days.
I tried to open the door like I always do (no remote key, just touching the handle) and the car would not unlock.
When I got into the car the GPS screen did not come up, the Info screen and energy consumption screens are also not working.
Before I took the car in for service everything worked fine.
I'm contending that the service people jostled something they should have just jiggled, or possibly jangled something they should have jingled.

I went skiiing this past weekend in Angel Fire, NM. When it was time to leave on Sunday I started the car and proceeded to undo the parking brake (I was parked on a n incline). As I press the button I get a message saying something like "Electronic Parking Brake Fault. Please Service". Then I press it again and it works. Is this something I can expect more of, or could it be due to the cold weather? It was 13F outside then at the time, and the car is a 2006 with 52K on it.

I have a Prius i-Tech 2007. I had gone overseas and came back after 2 weeks. On return, the smart key just didn't work. It didn't open the door...I took out the mechanical key and opened the door. Then I inserted the key in the key slot and tried to start the car but it just didn't react at all.

The car was locked and parked. But the beep you also have when the seatbelt reminder is on when driving was beeping ( at that same speed really fast beeping when you do not put your seatbelt on after a while it starts to beep really fast ). I unlocked the car and open the door and it kept beeping... now of course I can hear it even better.. it was indeed the inside beep.... I closed the door and wanted to lock the door again but before i could press the button it locked itself.... I opened and locked the car again.. after a few seconds it stopped.....

I owned a 09 Prius for 8 weeks, and after a total loss accident, we replaced it with a 08 Touring model. I have never experienced anything like this with the 09, but have multiple times on the 08 (though no real rhyme or reason as to when/why)
The originally happened the night we picked up the 08. I stopped at target to pick up some milk while the wife sat in the car. the car was left in ready mode. when the ICE engaged the car "surged" forward and was enough to startle my wife (who was the usual driver of the 08) enough for her to think the car was not in park (which it was)
We tried to recreate it after i was finished at the store, and while the car did rock forward, it was not as pronounced as the first time (though much more then We feel the car should move upon the ICE starting.)
Took the car back to toyota, and they preformed a full inspection and stated that everything was within toyota's spec, and to keep an eye on it if it were to happen again.
Well it has done this about 5 times in the last few days. The Dealer is looking in to it.

So I've noticed a few times now that my Prius horn honks about 5 times consecutively At random times while its parked and nobody inside. All the doors and trunk and hood are fully closed and the vehicle is locked when parked. I'm baffled as of what could be causing this. I've only owned my Prius for 2 months so I'm very clueless when it comes to it. What might be wrong?
