Prius (2004-09) :: 2005 - Brakes Abruptly To Jolt The Passengers Forward
Mar 21, 2013
I just purchased this car & thought there may be a learning curve to dealing with the brakes, but I think it may be abnormal.
When braking, I apply more & more pressure smoothly down on the brakes, but no matter how evenly, slowly, and smoothly I try to remain when braking, there is a point when it abruptly brakes to jolt the passengers forward and make me look like a terrible driver, lol. It provides for a smooth decline in speed until I'm almost stopped, then it does it. Jerks us to a stop. So I've learned to apply even pressure and right before that is about to occur, lift up on the brakes and restart that slow pressure to avoid it happening.
I can deal with this because it's not that big of an inconvenience once I've gotten used to it, but I am just worried it may turn into something more or who knows, could be an easy fix. I had the car inspected by a Toyota dealership before I purchased it, and they said that everything was in great condition aside from windshield wipers. It has 81,000 miles, one owner, clean carfax.

I have a Gen III Prius 2010 with about 50k on it. I've noticed over the past month that when the ICE shuts down at a stoplight, the car will surge forward a bit. If my foot isn't on the brake really hard, it will translate to the car actually moving forward until the ICE is totally off. If my foot is on the brake hard, you can feel it push against the brakes, and then the car settles back in place. It doesn't happen every time, so it still takes me by surprise.

I have a 02 Prius and the driver's side brakes are wearing twice as fast as the passengers side. Some times if I have to stop quickly the brakes pads continue to apply pressure on the rotor when the brakes are released. After a little drive they seem to go back to normal. Is this a sign of a bad caliper or master cyl.? I know before I purchased the car the front brakes and rotors were done, but they used after market parts

I have a 2008 Prius basic model bought second hand. There are two issues since I have bought the car; first it will roll back or forward when the brake applied, this happens on any uphill or downhill. I brought the car to Toyota service centre, they did a brake test, the test passed. but this doesn't resolve this issue. It just very weird. during driving, all brake works ok, but parking the car, if not in even service, it starts to roll.
Second, recently I hear there's a crack sound when apply the brake during low speed, especially during the stop/start traffic, and I notice mostly happens when the electrical motor in running. So when brake, the crack, like the spark comes from somewhere like battery. While brake to slow down from high speed, seems no sound. So I suspect it was from the battery or electric motor.

I purchased a 2012 Elantra Limited w/Tech last Wednesday and it has about 250 miles on it now. Downshifting is kind of hard. I've been driving with Eco mode on but have noticed the same thing w/o it on.
I'll get up to 45 mph and then let the car coast, every time the car downshifts a gear I feel it in the car. It causes me to jolt forward a little bit and is not very smooth. It shifts the same way while accelerating but then I don't really notice it b/c I'm speeding up.
It is annoying while just coasting b/c it feels like the car is braking a little every time it drops down a gear. Also, if it pushes me forward a little bit then the car probably is braking a little which seems kind of against the point of coasting...

I purchased a 2009 Hyundai Accent Automatic with less than 50000 Miles. I recently had to replace spark plug connector due to rats. Now, having issues with getting it to drive in the mornings. Description;I let the car warm up about 2 minutes before putting it in drive. Once I let my foot off of the brake the car begins to jolt forward and won't stop until I put my foot back on the brake. Even while holding the brake the car jolts but won't go forward. I have to put the car back in Park before it will stop. This goes on for about 15 to 20 minutes. Then, as if there were never any problems, the car drives as it is supposed to. *I have turned the car off and restarted but the car still jolts forward until it decides not to.I have checked the transmission fluid and it doesn't appear dirty but maybe low. Would low transmission fluid level cause this type of behavior? I am on a budget and a huge transmission bill is not really something I can afford right now. But I need to be able to get to work everyday. I can't imagine that the transmission is going up when the car has less than 50000 miles on it. I've had it since the middle of January.

I've a 2004 Prius. Had it for 3 years. 40,000 miles. No problems what-so-ever. 55 to 60mpg without any effort.
During the winter I noticed that when the petrol engine switched off - there was a jolt. (It used to be totally imperceptible.) Nothing drastic - I have to be on smooth tarmac to notice.
My Toyota dealer said this sometimes happens in cold weather. However, the weather has warmed up - and I can still feel the jolt.
Don't know if it's connected, by the central display diagnostic check tells me...
EMV. Code: 01-DC. Sub-code: 1C6-F6-1

I was driving my 2008 Prius and it abruptly slowed down and became undriveable. I had all of the warning lights - the red triangle master warning light, hybrid syatem warning light, and the check engine warning light. The car had to be towed home. The gas engine starts and runs - driving forward feels like the brakes are on - will not drive in reverse,. I checked the codes and had the following : POA1D, POA78, POA90, and POA94.

when i bought the t-reg the next day we drove 12 hours to NC, and every time we were on the pike for a while then pulled into a service plaza to refuel or take a break the treg would all of a sudden either jam the brakes or lug the transmission really abrupt just for a instant [URL]....................... it is hard to tell which it is. Kind of like not pulling in the clutch when coming to a stop..

About a year ago, the rear brakes became very suspectable to moisture and started grabbing. After a few stops the grabbing would subside, but I could still feel the rear brakes engaging a little earlier or more than the front brakes (the rear-end of the car would hunker down a little). So I replaced the rear shoes, the old ones had about 90K on them, not worn real bad and had plenty of life left. I made sure that when I installed them to clean everything, put a skim of silicone brake grease on a couple of the friction points and set the adjusters down so they would be able to auto adjust to the right setting.
The grabbing didn't stop, so I've lived with it for a while and finally got around to replacing the front brakes on the assumption that maybe since they were old that they may not be stopping the car as much as the new rear brakes were. Didn't work, in the back of my mind I'm wondering if there is possibly something wrong with the master cylinder and the balance between front and rear brakes is off. I'm going to go clean the rear brakes again today and crank the adjusters back to see if they adjust to a better position this time around. The drum and disc surfaces are in good shape and color.
Can the master cylinder get its balance messed up?

My 2005 Prius (86 K mi.) has a warning light on - brakes. Put on the scanner and came up with code P1116 coolant temp. sensor circuit stack for coolant heat storage system. Also C1378 - capacitor communication circuit malfunction. I'm just a shade tree mechanic but can usually fix stuff if I know where to start.

I've had my 2011 Prius II for two months, and I love it. One little thing bugs me, however. I have noticed that sometimes when I apply the brakes, the car lurches forward a little bit. But I keep the brake pedal on, and the car does stop. Is there something wrong with my brakes, or is this something that has to do with the regenerative braking?

I have a 2012 Prius with 15000 miles on it. In the year I have had it, I have had this problem a few times. On rare occasions while I am braking the car seems to lurch forward. In particular I have noticed it while braking and hitting a bump. The problem is that when this happens the car seems to jump forward while the brakes are being applied. My foot is on the brake when it happens, but I am not braking suddenly. That rules out any anti-lock braking. I have had the dealer look at it but since it didn't happen on their test drive they couldn't figure anything out. They did open a case on it in case anything comes up.

After washing my 08 GX and putting in the garage to wax dry I have found that the next time I get in it to drive-often a day or so later,the car will not move in reverse ( or forward) without me revving it up quite high to overcome the locked up pads on the rotors. Sometimes its even screeches the tires to get in unlocked. I just washed it and letting it sit outside for a bit to see if the sun will dry out the rotors/pads and that would work.

There are no A/C vents for the rear seat passengers. I would be downsizing from a 2005 Sienna and my kids have become accustomed to the rear seat comfort, especially the air conditioning vents directly over their heads.
I would like to know, especially from those of you that live in hot and dry climates, how well the front vents are able to cool the rear seat without freezing the occupants of the front seats.

For some time now, probably the past 3-years my 05 V8 has made this clunk/jolt when stopping the car on level surface. It very faint, but noticeable. When the car is in S, it doesn't happen. When stopping on a hill, it doesn't happen.

I have a 06 JDM prius with hard drive-based audio and navigation system. Today the car was parked in a ready mode with the stereo playing and the audio cut off abruptly. I investigated and found that all of the audio and navigation controls on both the steering wheel and center console were unresponsive. It is impossible to switch between modes I.e. CD, HDD,radio and the CD drive no longer rejects. Bluetooth pairing works but no sound coming from the driver side speaker when in a phone call. When the car is started the MFD shows that it's playing audio from the hard drive as shown below but there's no sound and its impossible to change tracks.

My 04 elantra starting acting up yesterday. It has started jumping/ rocking entire car when putting in to reverse. What might cause this problem. It is hard to describe what it is doing being I know nothing about cars. It is a large jolt when going into reverse.

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.

i have a 2006 f-150 xlt, i was driving it today and it started making a 5x5 beeping noise shortly after i started it up. I read on a few forums that that beeping is a warning about the passenger airbag sensor or something. anyways it went away and kept driving for 5 minutes or so when suddenly the dash went out and all the gauges dropped but i was still able to drive fine. A minute later the engine just died and i managed to pull over to the side of the road. now nothing works when i turn the key, not even a light, its just a dead weight, the remote locking doesn't even work. the only sign of life is a LED from my phone charger that is plugged into the outlet. the battery is only 2 months old so its not that.

Driving yesterday, (slowly down bumpy gravel road). My 2005 Prius locked up, the red BRAKE and the yellow (ABS) indicator lights came on. The car wouldn't go forward or back. I tried setting the emergency brake then releasing it - nothing. Still couldn't go forward or backward. I shut it off, turned it back on, nothing, tried setting the emergency brake then releasing it - I finally was able to drive, but the indicator lights were still on and when I tried to brake, there was nothing, nothing, nothing, then BAM the brakes grabbed and locked up. (This happened several times in a few blocks as I was cautiously trying to test the car out.)
I parked got out my owners manual which said "STOP, contact Toyota Dealer" so I had my car towed (first time ever for her to be towed) to my mechanic (he's out hunting, so someone else at the shop looked at it.)
The shop called and said it was showing a code of 1247 and said that it was a "malfunction of the brake pedal". They said they cleared the code and the lights went out. Their mechanic is going to take it for a test drive trying several 'braking scenarios'. (they better not wreck my car).
