Elantra MD (2010-15) :: When Decelerating Brakes Totally Disengaged And Car Will Lurch Forward
Jun 2, 2014
I have the not-so-uncommon grinding brakes problem too. In my case, however, there is a scarier difference: if I have to stop suddenly and hit the brakes hard, I hear the grinding and the car kind of shakes, but then as the car is decelerating, I will actually get the feeling that the brakes have totally disengaged, and the car will lurch forward! If I then depress the brakes quickly, they will engage again and stop the car. I've had a couple of close calls in heavy traffic when cars in front of me have stopped suddenly.
I guess that the grinding might be the ABS, but I've never heard of ABS causing your brakes to konk out completely! It's to the point where I'm scared to drive the car if I know there's going to be much traffic. I bought this Elantra last October to have a nice new car to drive my 6 and 4 year old around, so I'm very unimpressed, and scared, with the whole situation.

Twice today with cooling temps (45 during the day, closer to 30s on way home) while shutting down after being put in park my Prius did the "lurch forward and shudder." This is something new! Fuel has been purchased consistently from the same Shell station, she's garaged at night and MPGs are averaging 45... OK but nowhere near my great warm weather mileage. We are at close to 2200 on the odometer if my memory is working right - 2012 4 version. Happened once at the bank after work, once in the garage, level ground.
Not sure what is going on... this is new to me with a new car....

I have a brand new 2010 Passat. I am unable to achieve a smooth start from stops and the car will lurch forward when I take my foot off the brake. Any small input from the gas pedal produces a jumpy start to the acceleration process. I have about 300 miles on the car. I bought this for my wife and she is very uneasy about driving it.

On my 13 Elantra since the day I got it almost 2 year's now has always made this click noise when I disengaged the clutch and go, (not the clutch solenoid noise similar) I'll hear the clutch solenoid then almost like my left front brake was slightly sticking it makes a click like the caliper's popping loose!? I've mentioned it the stealership & nothing they tried to tell me the dust shield was touching however the noise came back within minutes I noticed it! It's just one of those annoying sound's that you need to figure out or go crazy, stick model, could it be the clutch fork or bearing releasing just can't figure it out.

When coasting to a stop, I have noticed when the rpms reach 1000-1100 they jump up a little bit. Sometimes you can even feel the car lurch forward just a tiny bit. Is this normal for a car downshifting??

Intermittent problem, noticed mostly at low speeds, where car will buck or lurch forward. Most noticeable when accelerating after a slowdown, i.e. applying gas after coasting. No check engine lights, oil & transmission fluid is full. Car has 105K miles, tranny & coolant flushed every 30K, oil changed every 3K, tuneup w/plugs& wires @ approx. 93K, timing belt @ 70k. This car is a gem, mostly driven on the highway that has been perfect until now. Things I've considered doing: replacing timing belt, transmission solenoid, computer sensor that controls tranny. My suspicion is its tranny related but maybe not. Is there a way to check/set the timing on this car? I remember years ago using a timing light on my chevy. This is weird, it will run perfect smooth in the morning and rough with lurching in the afternoon. Could be a total coincidence but it seems to run ok when its cool and not so when it is hotter.

So I just bought a 2004 Ford Focus. I did not drive above 15mph when I tested the car due to the lake effect snow that was occuring. Now that I own the car I have noticed if you try to stop going over 20mph the car starts to stop but last second it lurches forward a little bit. There is also a grinding noise that sounds like its coming from the back and a loud vibration that sounds like its coming from underneath the middle of the car. I'm trying to figure out if it is the brakes, tires or a leak in a brake line (those are all things my dad said it might be).

I have a problem. 2002 F-350 4R100 tranny. Put a reman transmission in about 30000kms ago. pulled excellent with no problems. shut it off for night. In the morning it had absolutly no forward and a little bit of slipping reverse for a few minutes now it is totally dead. No movement either way. The OD on off flashed a few times but not anymore. Put a Genisys scanner on and no codes at all. What could be the issue?

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.

2010 F150 for the past 15,000 miles I have been experiencing a nasty repetitive surge when moving slowly forward with the brakes on, as you would do going through a drive through. The truck shakes when this happens and is very noticeable. Ford reprogrammed the transmission module, and now the surge happens twice as fast. What was the remedy? This is my first Ford after only GM products for the past 30 years.......and I hope they can find a resolution soon.

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 don't know if this is related, but my car has not shifted as well as it did before I gave it my oil change. The car only has 3K miles, new Hyundai oil filter, and Mobil 1 Synthetic 5w-20.
It's not a major dip in performance, but enough for me to know its different. One example is when I come to a stop, the car seems to surge forward a little bit. Another is that is shifts hard from time to time when I give it gas.
Going uphill, it just doesn't have the power like it did. Also, it feels that it's not in the right gear..like 5th or 6th gear. It's hard to describe the symptoms. The weird part is that the MPG is the higher than normal.

My parents have a 2010 Hyundai Sonata. About a month ago my mom noticed that when she starts to brake, the car stops fine but then it stops again almost, with a loud thunk. The best way to describe it is that you press down the brake, the car stops, then a few seconds later the car feels like it is lunging forward and stopping again with a sudden thump. (Although I don't think it really actually moves at all).

After driving in the rain and starting the car again after a few hours (as in starting the car again after work, or starting it first thing in the morning) the following happens: As soon as I release my foot from the brake pedal to go into "drive," there is a "thunk" sound from the rear of the car as well as a lurch. A soft "thunk" may have a soft 'thunk" sound, but a louder thunk will have a pronounced lurch/jerkiness from the rear. The car drives OK and has no problem with braking when I apply the brakes.
It happens only after driving in the rain. The dealer says the sound and movement are the normal result with disc brakes wearing off the rust on the rotors. Other wet weather concern (happened once): while driving in a couple inches of snow, the brakes began to grind and eventually failed to bring the car to a stop. Dealer rotated the rear rotors (due to uneven wear, although I had the car only two weeks at the time) and installed new rear brake pads. He said grinding brakes on an Elantra are normal in rainy, snowy, and dusty conditions. Is my car really safe to drive? Is there a problem? I'm considering trading it it as I don't feel safe. It is an otherwise OK car.

I've notice this several times when leaving from work to go home. The first quarter mile I will be starting off nice and easy, the engine is on and then suddenly a lurch of power. Now its not giving me a wipe lash! But I can defiantly feel it and out of the corner of my eye can see my passenger's head move back slightly. So not so subtle either. It will only happen once.
It is not going from battery to gas as I mentioned engine is already on. I am in eco mode the whole time. I am not hitting the gas any harder. And I am not going into the power band all the way right of the bar. I am staying steady in the eco area.

Well my car is back at the dealer, again. Last week they replaced the brain for the ABS and everything on the right rear. Well driving up to and back from Redding, Ca.the brakes started dragging again on the right rear.
This time the rotor had a orage tint to it from the heat when I looked at it. The gas mileage sucks and now this. If I have to take it back for a 3rd time, I am getting rid of it.

I new 2015 Elantra LTD. has terribly grabby brakes in a certain scenario. That scenario is, it is rainy or wet, and I'm going very slowly, like in a parking lot. When I touch the brake pedal very lightly, the car stops abruptly! And I mean abruptly. As quick as the car comes to a halt, and not intended to, I suspect it is the front brakes. Not sure if it is the new brake pads acting peculiar, or some other issue. But, the brake grabbing problem isn't present when its dry and going slow, or when I'm going normal speeds when its wet.

The brakes on my 2014 Elantra Sport grind when they are wet/it's raining. They seem fine when dry.

so in my 2012 Elantra GLS, I just spent $500 on new brakes rotors ... and it's been roughly 7 or 8 days, and I am seeing some rust on the brakes and rotors, I'm no expert on cars, but it doesn't look normal. Hopefully, it is normal so I can stop stressing.

I'm not sure if this is the proper operation of the disc brakes because all my cars in the past were front disc and rear drum. A search turned up nothing useful so here I am.
To me, the sensation I'm having is the rear brakes are activating before the front. I sense the rear going down before the front. I don't hear any squealing or grinding. I also don't feel any vibration while braking. Perhaps it's a sensory illusion? Or is this the normal operation of disc brakes?

It is 10 degrees now (-12 C). I softly engaged the clutch and noticed the car wasn't moving. I tapped on the gas lightly and the car was trying to move, but couldn't. I finally gave it a lot of gas and there was a huge POP sound. When I park my car, I leave e-brake engaged. Are brakes suppose to stick that bad in cold weather? The Pop sounded like a .45 Pistol!!
