Elantra MD (2010-15) :: Nasty Sounding Thump In The Rear

So I have a 2011 GLS with a little under 36k miles on it. Every time I drive over anything from a small to a big bump, there is a nasty sounding thump in the left rear of the car. I do have a sub back there, but it weights well over 90lbs so I can't think its that moving around. I do need new tires soon so i do not know if that is a factor at all.

Elantra XD (2001-06) :: Brakes Making A Grinding Noise And Thump Sound Coming From Passenger Side Front

So, last week I got my transmission replaced and they also had to replace the CV axle because it was damaged beyond repair when the Transmission self-distructed. They drove it after all the repairs and said it was driving fine, just that it had a belt squeak.

On my way home (30 min drive) about 10 minutes in, still in the city, my brakes start making a grinding noise and sort of a thump thump thump when I brake which sounds like its coming from the passenger side front, it makes me really nervous. It doesn't sound like any brake grindy noise Ive ever heard before and it wasn't making any brake noises before it broke down. (On a side note: it also made a weird noise maybe the first 3 times I drove it after getting it back and I turned the wheel hard to back out of a parking space, that used to be when I heard the belt squeak but I haven't made it squeak since I got the car back.)

Everyone I talked to said it sounded like it needed new pads so tonight I bought new brake pads and rotors for the front and got everything taken apart. The rotors didn't look bad at all, just some light surface scratches, nothing deep, no warping I could see, and the brake pads look almost brand new. I did notice that the inside brake pad on the passenger side was missing its little metal plate that is usually between the caliper and the pad, so I went ahead and replaced all of the brake pads hoping this lost metal plate was the issue.

I also turned the rotor by hand on each side while the brake pads were off and the only difference I could notice was when turning the passenger side one it made a little more noise almost like it was loose.

I got everything put back together and drove around the neighborhood with my boyfriend in the car to listen, the grinding noise was gone and it seemed to brake really well (never got above 30 mph.) However, on my way to return the rotors to advanced auto (45-50 mph) it started making the thump thump thump noise but without the grinding, still on the passenger side. I can feel it in the gas pedal and now it not only happens when I'm braking, but also any time I let my foot off the gas pedal. The only time I dont feel/hear it is when I'm accelerating.

Elantra MD (2010-15) :: Jerking Feel With Transmission When Switching Gears

This is the second time I notice a problem with my 2014 elantra base model. The car only has 13000kms and today the car acted with a weird behaviour. This car has a manual 6 speed transmission.

Out of the blue the car jerked like it had a problem with the transmission switching gears which is weird as this is a manual.

The second time this happened the wife was driving and she said that she was in is third gear and she pressed the clutch and the brake at the same time and she felt a small jerking feel in the clutch like it didn't engage.

The problem is that I cant reproduce the problem. The car is still under warranty and I don't want to go to the dealer with a problem that I cant exhibit.

Elantra MD (2010-15) :: Pulsating Vibration When Stopped / Jerking Feel

My car gives off a pulsating vibration when I'm stopped (at a light, or in my driveway, for example). Its as if someone with huge bass is sitting next to me, but I'm alone. Its a weird "jerking" feel where I can feel my seat shake like a mini earthquake.

I've tried researching "rough idle" but don't fully understand it. Rough idle implies a clogged intake, which kind of makes sense I guess. I have something better than "my car kinda vibrates when I'm stopped".

Its a 2012 Elantra Limited, all stock everything, 53981 miles.

Elantra MD (2010-15) :: 2012 - Pulling And Tugging While Uphill Driving

I have a couple of questions. Been driving for about 4 weeks now. Just took it to Hagerstown, MD yesterday and noticed something odd when driving up the mountains. (We have lots of mountains to travel up and down out here in western MD) When I would get to 3k RPMs, I would notice something strange, kind of like a pulling or tugging. (Think of it like a circle with a line somewhere no hit. Every time you hit that line, there is a little vibration or tug, kind of like if you have a rock or something stuck in your tire and you hear a noise every time you hit that spot on the tire against the road).

However, it only occurred when going up the mountain at 3k RPMs. If it kicked up to 4k RPMs, it didn't happen. It I was below 3k RPMs, it didn't happen. Is it normal? Is it related to the Active ECO system? I didn't try running it uphill without cruise control on. Could it be because I had cruise control in use? Just wondering if this is normal. I was reading the manual and it did state that you would notice a difference when Active Eco was engaged when going uphill as the engine would be a little less powerful or less quick to gain power. Also, what is "sport mode"? The plus and minus signs to the right of D on the gear shift?

Elantra MD (2010-15) :: 2012 GL Jerking Whenever Switch The Gear From Park To Drive Or Reverse / Neutral

I have an Elantra 2012 sedan GL and last year i tried installing HID's. It worked for a whole but then it stopped after. I learned that it wasn't getting enough power so then yesterday I bought a wiring kit to be able to wire my HID to tap to the battery to get more power. Everything was fine till I got to work but when I had to leave work., there was an issue. Whenever i switch the gear from park to drive or reverse or neutral. My car seems to jerk. And when I'm driving and it changes gears, it also jerks. Kind of the same thing how if your driving a manual car and you change gears wrong. This happens when my lights are off. But when i turn them on it then stops. And when i turn it back of it doesn't do it anymore.

Chrysler - Newyorker :: 1992 - Misfire / Jerking Going Uphill

I have a 92 (3.3L) New Yorker 5th Avenue that has makes the car jerk badly going uphill and occasionally makes a backfire / misfire noise. It is a general jerking, not localized (right / left front) by feel. It starts ok and runs smoothly at idle but once you put it in drive and start acceleration, it begins to jerk. It has over 200k mi. I have had the fuel filter replaced, new plugs and plug wires put on. Mechanics have ran codes on the engine and transmission and tell me that no bad codes show up.

Lexus GX 2010+ :: Engine Sound When Accelerating Or Going Uphill

I purchased my 2014 GX a couple of months ago and already logged in about 2K. The car has been great so far. The only thing that I'm not so used to, is a strange feeling when accelerating or going uphill (even slightly) - I can feel the engine roar(?) through the steering wheel - I can't really describe it well - it's not a vibration per se, but more like you feel the engine working harder than usual through the slight vibration of the steering wheel. This is my first V8 car - I used to have a V6 Acura MDX before, and never felt that. There is a good chance this is normal for a V8 based truck, but I wanted to get others' input.

Ford F-150 (2004-2008) :: Driveline Jerking When Try To Accelerate Sometimes On Flats / Rarely On Downhill But Always On Uphill

2004 F150 FX4 5.4L. I drove from Vancouver to Edmonton and back this week and I started to get some issues. If I'm in overdrive at highway speeds, from about 90km/h to 120km/h give or take, which would be around 1600-2100rpm, and then I try to accelerate, sometimes on flats, rarely on downhills, but always on uphills, the truck will begin to jerk fore and aft. It feels like it's something through the driveline, either the driveshaft or the differential, but I really can't say for certain as I'm stuck in the driver's seat while this is happening.

If the truck downshifts or if I take it out of overdrive, i.e. getting the revs up high, the problem is no more. Other than the issue I'm having, it operates perfectly so this is very odd. I know that overdrive isn't a hill climbing gear, but normally an engine in the wrong gear will simply lug along until it's downshifted. The entire truck jerking shouldn't happen.

On my way to Edmonton, I noticed that this would cause one single, minor jerk. This is my way of describing it, but it was like the driveshaft had spun freely and then promptly re-engaged with the differential gear, causing a clunk. I doubt that's actually what happened, but I'm just trying to explain the sensation. It kind of feels like trailer jerking.

On the way back to Vancouver, it was a lot worse. Like I said, the whole truck would be jerking about once per second but there was one time that I found the sweet spot and it began jerking rapidly, twice per second. I threw it out of overdrive to stop this but the vibration caused the check engine light to flash a few times but it went away and didn't stay on.

What I might be up against? Been doing a little research. Seems as though this is common and it's supposedly the spark plugs, but those only have 50,000km on them.

Elantra MD (2010-15) :: Jerking From Time To Time While Driving

I am new to the world of maintaining my own car. I had an issue this morning when I drove my 2011 Elantra. The car started jerking from time to time while i was driving. So I ended up going back home and swapping cars. Other than a coming up oil change, what could the issue with my car be? I am at about 43k miles.

Elantra XD (2001-06) :: Manual Transmission - Thump When Shifting

I've been hearing a quiet 'thump' when shifting. In particular, when first letting up the clutch starting out in 1 but also when shifting between gears when the clutch is fully down such as from 2->3.

I thought perhaps a fluid change was in order since I'm at 110,000 miles. It didn't make any difference. (I used Mobil 1 GL5 which according to independent tests is safe on yellow metals.)

So then I wondered if it's the engine mounts, but I'm not sure what it sounds like when they need to be replaced or if simply shifting between gears while driving as described above would cause a worn one to 'thump'.

Elantra GD (2013+) :: Thump Noise Almost As Transmission Was Shifting When Taking The Turn

Overall, my wife and I like the car. It feels solid, and so far we have about 950 miles on it. Today though, something weird happened.

I was driving, and we were getting on the freeway after crossing an overpass, so it the on-ramp was one of those sweeping, downhill, 270 degree curves to the right. Nothing out of the ordinary.

So I let off the gas, and I'm taking the turn, and there was this "thump!" noise - almost as though the transmission was shifting. The car shuddered. Then it did it again.

It was disconcerting, almost reminiscent of our wacky dual-clutch transmission issues we had with our 2011 Ford Fiesta. Now granted, its a bit of conjecture since I don't know what could have caused it. I wasn't going quickly enough where any stability control mechanism (ESC) should have kicked in... so I'm not sure what else could have caused it. Undoubtedly I'll be testing it again to see if I can reproduce it, but its got me concerned.

Elantra XD (2001-06) :: Loud Thump When Go From Park To Reverse / Car Stuck In High Gear

What can I do about my car it's not shifting, it's stuck in high gear and when I go from park to reverse it makes a loud thump. The check engine light came on and the codes are transmission control module it's a 2006 and only has 30,000 miles on it. It's hard to believe it's the brain so we changed the fluid and cleaned the sylinoids but then when I drove it around the block I put it in reverse it didn't make the loud noise and it shifted fine for a minute before I got around the block and almost home it made a loud banging noise and went back to not shifting again. What the problem could be.

IS F (2008-2014) :: Exhaust Thump Sound When Car Is Rolling Along Around 25 MPH Or So

Having a sound from my exhaust. Basically when the car is rolling along around 25 MPH or so, and my foot is not on the gas, as soon as I gently touch the gas pedal, I get a soft "thump" sound. This basically tends to happen in 5th or 6th gear only.

The previous owner had done a muffler delete on the stock exhaust so I figured there was some sort of back pressure issue because of this.

Finally out of frustration, I sprung for a new Borla Catback exhaust system, hoping to eliminate this issue. While the thump sound is slightly less, it still happens!

Lexus LS 2007+ :: Thump Sound When Engine Turns Over

For last couple of days the car is making a Thump sound when the engine turns over. then it gone- single thump sound....It only happens in the morning if the car is sitting in the garage overnight. I do not hear it if i park the car at work after 8 hours does not make the same sound.

I also feel it takes a bit tad longer to start the car(again only in the morning)- i thought it was the battery but the battery has been replaced 2 years ago.

i will try to record the sound tomorrow and post it. the car is fine once started no funny sounds or anything. Its a 2011 with 71k miles on it.

Elantra XD (2001-06) :: 2005 - Jerking Soon After Accelerate

My 2005 Elantra is jerking soon after I accelerate. It does not jerk at any other time. It's not a hard jerk. Sometimes it doesn't jerk at all after acceleration. When it does jerk, the rpm jumps up too, and goes back down after the jerk.

I took it to a transmission shop and they checked the fluid and used a diagnostic thing to check the electrical components, all of which were fine. Is there another possible reason for this jerking?

Hyundai - Elantra :: Jerking At Random While Shifting

My alternator recently died and I took my car to a shop to have it replaced. Since receiving the car back, I've noticed that the car seems to jerk at random while shifting. It seems to happen most when shifting from 1st to 2nd. This problem didn't exist before I had my car maintained. Any chance this is related to the work done and is something easily fixed or is it just coincidental timing?

It's a 2004 Hyundai Elantra, at 120k miles,,,

Elantra XD (2001-06) :: Engine Light While Driving And 2nd Gear Taking Time Shifting - Thump On Transmission

O.K. first of all I had an issue with the Odometer pointer being jumpy. Sometimes it wouldn't move. Now I replaced the input sensor at first and did not fix the problem. I replaced the output sensor and fixed it. "BUT", Now, I have a problem with the transmission shifting. I get an engine light while driving and the 2nd gear seems to take its time shifting and when it does it make the left side drive shaft kick in hard and spends my wheel to a screeching effect. Plus a thump on the transmission. I rechecked the sensor for connection and reinstalled. Drove the car still have the same issue?

Elantra MD (2010-15) :: Engine Has A Ticking Sound

My elantra has around 7000 miles on the odometer. I have noticed for a while that after sitting for a few hours or over night the engine has a ticking sound to it. The noise will last for a few minutes then goes away. I figured that the cold weather might have been the cause. Not it is almost summer and the noise is continuing. Im not sure if this is normal for these engines. but any other car i have had has not had an extended tick at startup.
