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?
View 19 RepliesI 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.
View 9 RepliesI 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.
My car has 140K miles and has never required any brake work.
It is difficult to describe, at freeway speeds they seem to work fine. Around town, say 45 mph and below, the brakes work as though I'm a 16 year old learning to drive for the first time. I'll press a little, and get nothing, press a little harder and they really grab and the car lurches. But it also seems inconsistent, it doesn't always happen.
This has had NO perceptible impact on the "grabby" braking performance. Further, I would describe the hydraulic only braking as "excellent", they work just fine and I do not get any of the pulsing or weird brake behavior when braking with the car in neutral.
While driving idle seemed to increase. Noticed at red lite where van seemed to want to move forward with brakes applied. Went to parking lot put van in park engine RPM rose to around 2500 RPM on it's own. Opened hood and fiddled around with a wire???/hose thing near the throttle control line (wire that connects foot piece to engine). A bunch of black powder (carbon?) fell out. Turned the van off then back on a couple of times. On the third time idle returned to normal and has operated normal since. What caused this? What do I tell my mechanic? What was the wire/tube thing (it entered what I assume is the air intake at a right angle) right in front of where the wire from the foot control hooks up.
View 1 RepliesMy car is a 2011 BMW 328i Coupe, currently at 24K mi. Recently i found my cars brake pedal get sticky after Ive applied the brakes from time to time. But nothing server. My routine schedule maintenance will be coming up soon, so i am just wondering what could be the probable cause. Could it be the brake fluid?
View 6 RepliesSo I was told I had a brake light out? Went and bought new bulb and replaced. Turn on headlights and the single filament lights. so when brakes are applied the second filament should light up that give the brighter affect.
Well when brakes applied the bulb goes out completely? Take foot off brake and the single filament comes back on. The other tail light operates as it should. Even used bulb from working tail light with same results.
Car started fine but stalled on first brake application with the skid-control light illuminated, restarted fine but stalled again on next brake application (skid-control light stayed on). Decided to head for the dealer which was only a few blocks away, drove there knowing that it may stall when brakes were applied (engine would start, idle and operate when driving but the problem would only occur on brake application.... approx when the transmission would down shift to third or second gear). My last stop before turning into the dealer's parking lot, the engine quit and refused to restart.... finally came back to life after about 5mins and was able to complete my somewhat dangerous trip (whole journey was on very quiet back streets). At first I thought it could be related to the infamous brake switch but the service rep informed me that they couldn't communicate with any control module with the scan tool. Now I sit and wait, hopefully they will call with some good news soon.
View 9 RepliesRight this clicking noise is really annoying me now, every time AFTER i brake i hear this click, the faster i stop the louder the click is, also when I am in neutral and suddenly rev its clicks sometimes but rarely, I am thinking it could be a loose exhaust somewhere? Its definitely coming from under my foot area. When I brake cornering it clicks too. Checked my control arms and everything, that's not rattling at all? Need to get rid of this click sound!!
View 3 RepliesSometimes when I stop at a light about 5 seconds after I come to a complete stop, I'll feel a bump in my transmission likes its trying to lunge forward. Today I started my car and put it in drive and when I did so with the brake applied, it was rhythmically bumping once every 2 second or so, almost like a heartbeat. It did it about 15 times and I shut my car off, started back up and it hasn't done it since. I know the first issue is somewhat common but the second one where it kept doing it was really weird. It has about 35k miles and is already on its second tranny(per car fax changed at 2k).
View 5 RepliesJust got a 03 Used Santa Fe 2 weeks ago... 79,000 miles
1. Car "lurches" when at a complete stop w brake fully applied out of no where, so strong that I could easily rear end someone...
2. told dealership car was pulling to right, they said (after some teeth pulling) that a ball joint was replaced and Santa Fe's don't need alignments but in MA this is part of state inspection and considered a safety issue, needless to say, they say I have to pay for it...
3. Rear brakes seem to be hanging up...
All I want is the issues fix.
Having issue which the car moves a bit after putting it on Park?
When I set the car to P and release my foot off from the brake pad, the car lurches forward a bit then locks itself down.
Another issue i have with the brake is when I fully stop and release the brake, i hear a noise. I can't really describe the noise.
I've had my 08 r32 for about two months now, it has 93k on the clock. The dsg is great in everyway except in low gears/speeds. Especiially in traffic, it lurches forward or slows down rapidly like it dosant know weather to shift down to first or stay in second. Jumpy when starting off in first like I have to feather the gas pedal just right so it doesn't jump off the Line.
I took it into vw service center last week for diognostics test, they said everything was fine trouble code wise but they wii send the results to vw tech center and ask for advice. I got a call back today they want to do a cycle test, test drive the car with reset values and then cycle 6 times. From cool back upto operating temp etc and find out the results.
I have a 1986 Volvo 240. It has a button to push on the stick shift to put it in 5th gear. It drives and works fine except when I downshift from 5th gear. ..then it seems confused and has a hard time getting back into gear, it kind of hesitates and lurches forward. It will not go into reverse after it has been in 5th gear until I turn off the ignition, and start it again.
View 2 RepliesIt's hard to drive the Mk6 smoothly at low speeds. Creeping along at a snails pace the car lurches forward while trying to crawl along at about 5 mph in first gear ( 6 speed manual ).
I remember reading about replacing something that will cure this 'hiccup' in throttle response. What the part is? Is it a diverter valve or something ?
What the fix is for my 2007 Mercury Montego Premier? When the car is in drive and the car is either stopped or at a slow speed such as at a stop light or pulling into a parking space, the car lurches forward. It is almost as if the computer is telling the car to step on the gas. I am concerned for my 16 year old daughter to be driving the car and have the car suddenly accelerate and get into a collision.
View 4 RepliesI have an RX 330 with about 154K on it. I have noticed recently that (from a stop) when I press the gas there is a slight hesitation before the car lurches forward and continues down the road. Also, in general the car doesn't seem to have the get and go it once had. What I should look into to determine what might be causing this problem?
View 2 RepliesI have searched a decent amount on this and it seems like there is a whole list of items that could cause these problems. The car is a 2008 Passat 2.0T with the tiptronic. It is the early 2008 so it still has the FSI motor. It only has 53k on it and literally just came out of warranty a month or two before this all started happening.
It all started with the CEL coming on and the went into limp mode. We shut it off and turned it back on, the car went into limp mode again but upon the 3rd restart the car started and ran just fine. Then for a few weeks we just had a CEL (I don't know what code it was because I never scanned it at the time). Now as of lately the car is have a terrible rough idle, and at stops it will start kinda shaking and lurching forward. Sometimes it will also have a noticeable misfire upon start up. Also after going at highway speeds for some time the car will start to produce a squealing noise when not producing boost.
A few days ago I scanned it and these codes came back:
P0110
P0101
P0102
P0104
P0108
P0171
The first 5 IIRC are related to misfires and the P0171 is a lean code.
At first I thought this was the PCV valve because I had read about the lurching and the squeal that someone else had from that but after reading up more on things I am worried the P0171 is from the cam follower.
At this point I am just very tired of hearing my wife constantly complaining about the car. I want to try and figure this out without throwing part after part at it. I can't afford to buy items just to find out they aren't fixing it.
Our gen 1 has developed a (currently minor) noise issue when braking. I'd like to sort it out before it becomes serious.
The brakes are still strong, and the regenerative system appears to be working. When the brakes are applied (even gently) there is a pulsing raspy sound, seems like it is coming from the front, driver's side. It is more rapid at higher speeds, and louder during rapid deceleration. I guess I'd call it 'grinding', although this is much less unpleasant than the classic 'grinding brakes' I've heard on other cars.
In any other car I would figure a warped rotor or worn out brake pad. But I had imagined that the regenerative system handled light braking, and conventional brakes took over beyond a certain threshold. Now I'm hoping they work in tandem, even on gentle braking and this is just a boring, simple pad issue.
Just had a couple questions, The first one is in regards to the brakes on my '09. I've read that the brakes themselves don't actually kick in until you are going 7 mph or less. Anyways, when I am coming to a stop it is not necessarily smooth. I try my best to apply even pressure to the brake, but I basically come to a jerky stop. Is this common in a Prius? I bought my car certified pre-owned last month and I know the brakes were one of the checklist items.
View 2 RepliesComing to a left turn signal I was anticipating it turning red on me, and I drove into the turn lane briskly 30mph and then applied brakes as I made a u-turn. It sounded like a cross between dragging the front air dam and metal on metal brake grinding as I made the turn. Stopped immediately and did not scrap the air dam and all front end components checked out, okay. Car is driving just fine now, has only done this once.
