Elantra MD (2010-15) :: Bad Gas Mileage - Loud Grinding Noise On Hard Braking
Apr 4, 2013
I bought a new 2013 Hyundai Elantra Coupe this past August and this is my first car.
My first concern was that Hyundai advertises 27mpg in city and around 37(?) for highway. I acknowledge the fact that Hyundai recently had to lower their mpg estimates for some of their cars and provide reimbursements but however, these reimbursements are for 1-2mpg difference. My car after more than 6 months is still only getting about 14-15 miles on a casual drive in the city and only about 19-20mpg combined and about 24-25 on the highway! I am only getting about half the estimate for in city! I do not drive aggressively. In fact I am a pretty safe driver since I am a new driver and cautious about everything. I am also using premium gas on my car. I called the dealership I got the car from and they were trying to tell me about the reimbursement program which I already knew of... The reimbursement based of the 1-2 mileage difference is not what I want. I want to fix it and get close to the estimated mileage as I can. What is the best way to go about doing this?
The other issue is that sometimes when I hard brake, my car makes a loud grinding noise. My dealership's service center said they could take a look at this. I was mainly wondering if there is anything I should be concerned about for this?

I recently purchased a brand new 2013 Hyundai Elantra and I have noticed that I sometimes when I brake fast but not fully slamming on them from going about 60-80km I hear a loud grinding noise. When this happens the roads are dry so I know that it is not caused by slippery or wet roads.

I have another issue. I just started having problems when braking. Every time I brake there is thing loud grinding noise that sounds like it coming from the back tires but there isn't a squeaking noise like there is where you need new brakes what else could this be??

Passat Front End Noises? Loud "crack" noise when stepping on gas after hard braking....I thought...control arms gone again (replace em @ 55K miles)...so I replaced all the control arms... NOISE LESS but still there! I've replaced motor mounts and just checked them..no leaks, so engine shifting cant be it... I replaced the "stretch torqued" subframe bolts when I did lower rear control arms..so they're tight...What can it be??

2001 Hyundai Elantra, with an automatic transmission.
1. I am experiencing a "grinding" sound upon my initial acceleration from park? This only occurs when the car has been sitting for a decent amount of time and the engine is relatively cold. To give you more detail: I start the car, throw it in gear and begin to accelerate. The grinding sounds is almost instant and sounds horrible. It is fairly consistent how long it lasts and generally once the car shifts to 2nd or 3rd it goes away. I do not hear it again until I park, leave the car for a while, then start it up and begin driving again.
2. I am hearing a "tension" like noise, also a little like scraping, when I brake at slow speeds coming from my driver side front wheel. I recently had my brakes replaced so I know its probably not the pads and at the time the rotors looked fine too. It is not a constant noise during the breaking either meaning, I apply the breaks, i hear it for a second, then it goes again, then it comes back, then goes away. Again it sounds like a mix between scrapping metal and tension.
What it could be, what I could look at on my own or how to get it resolved?

I have a weird problem with my 2008 Elantra GLS 86K Miles on it. I did a couple of searches on this problem but didn't find any threads. About a month ago I noticed that when I braked hard at highway speeds 65 to 70 Mph I would get a noise that sounded like I was driving over the rumble strips on the side of the road. The rumble was the same frequency no matter what speed you are going, it doesn't get faster or slower. The problem slowly got worse to the point that it would happen at 25 to 30 Mph. The noise sounds like it is coming from the front but I can't tell which side. I figured that it was probably rotors and time for a brake overhaul so I replaced the rotors, pads and hardware on the front and the back. I used synthetic brake grease on the slides and guides. I also replaced the brake fluid with synthetic DOT 3.
When I did the back brakes I found that the wheel bearing on the passenger side was leaking lots of grease so I replaced it with a Timken bearing. (I live over an hour away from the nearest dealer so I did the repairs myself.) While I was working on the bearing I pushed the rear shock up and out of the way and it stayed in the up position for quite a while, aren't the shocks under pressure and usually push right back down? (Just an off subject thought) Well after replacing the bearing the rumble strip noise went back to just happening at speeds from 45 Mph and up. I was also thinking of pulling the fuse on the ABS and seeing if the problem goes away but will pulling the fuse hurt the car in any way or trip a code? I know what the ABS sounds like and this is not the same noise you get when sliding on ice.

The topic is as much as I can say to what my car's problem is.

Early this week my car started making a loud knocking/rubbing sound (Kind of in between when your brakes are ground down to the rotor and a knocking pattern).
FIRST, it started only when I turned slightly left or left.... NOW, it's doing it as I go straight and when I turn to the right as well... oddly enough it's not as bad when going left anymore...
What this could be?? And if it's an easy DIY fix..... (maybe a link on how) and how much the part(s) might be?? I've taken video (for sound as I drive)...but not sure if I can upload it (size limit).

Having problem with my car (2001 Elantra GT) - over the last month or so it's been occasionally making a very loud (not but consistent) grinding noise coming from the front of the car when decelerating at low speeds. The noise sounds like gears slipping over each other but cuts in and out. It's pretty loud and not a nice noise to hear! Sometimes it makes the noise when I brake firmy but not until I reach lower speeds... mostly it's just when coming to a stop, but it did it once last week when I was pulling very slowly out of a parking spot and not even braking.
As it's become more frequent (going form maybe once a week to several times every car journey) I have started to feel something in the brake pedal also, like there's something kicking it from behind. I took it to a mechanic and had to pay a ton of money to get a broken front left ABS ring replaced (it also had the front right ring replaced in May), and within 2 minutes of driving away from the place the noise was back. Before I spend even more money that I don't have on taking it back for extra diagnosis.
I'm told that this is almost certainly the ABS system that has a fault even though the ABS light never shows except when I start the car, and I've taken the fuses out of the ABS in order to confirm that it is. I haven't heard the noise after a few days of driving with ABS unplugged so I think we can be reasonably sure here. Is there anything that I can check myself or test (I'm not very handy when it comes to cars) or can you tell from this information what it's likely to be? Other things that I've noticed with the car which may or may not be relevant are:
- the warning lights for brakes, ABS and TCS are all lit with the fuses for ABS1 and ABS2 taken out. I take it this is normal for all 3 to illuminate with the fuses out?
- since unplugging the ABS I've noticed a slight metallic squeal from the brakes as if the brakes are worn down. Didn't notice this before I unplugged ABS though it may have been there, not sure.
- sometimes when going over a speed bump or just a minor imperfection in the road I hear a clunk in the front of the car and feel something move in the underside of the car. Happens mostly at lower speeds also, but not if I go over the bump really slowly.
- in the fuse box when I took out the ABS fuses I noticed there was a bit of minor melting/brown burn marks on the top of the connections marked (iirc) ECO3 and ECO4 on the diagram (large white connectors). Is this anything to be concerned about?
- sometimes when I have air coming into the car through the air vents it will become significantly warmer for a few minutes, then slowly go back to normal. Can't think of any circumstance that links the times when this happens (eg. speed, weather etc).
- the oil pan has a leak which is on the list of things to fix when the car works properly.

I have a 2007 Elantra with 138,000 miles. I never had any slipping or jerking or reverse issues in the past. I got into the car put it in reverse just fine then put it in drive and nothing happened, I put it in park and the car kept rolling like in neutral and started making a loud grinding noise. When I put the transmission in any other gear the noise stops but will not move and acts as if in neutral.

I have an early 99 F250 4x4 7.3L..... 4R100....
Brief history, a while back on way home from work I let off of the accelerator and had a loud gear meshing like grinding noise, got back on the accelerator and went away, let off and back, so I quickly stopped and pulled over, went through the gears and reverse, everything seemed ok,??? went on my way, got home parked the truck and went about my evening. came out next day to leave and truck wouldn't move in reverse, forward but not reverse. long story short I was told that the snap ring internally probably came out, I have heard of this being a big issue with these, so I set up for it to be rebuilt, got it back and installed and still same issue, what the crap so I ended up having to pull it back out and amongst my own trouble shooting I found the simple issue and was the nylon riders on the 4hi/4low shifter fork were completely gone and allowing the planetary group to free float in and out of 4x4 neutral!!! NOW on to the issue at hand. so far only thing has been done is rebuilt and those fork riders replaced.
now I can move but 2-3 upshift under a load(more noticeable) has a delay going from 2nd to 3rd and under a load it hits hard. I talked to the guy that rebuilt it and he said that the rebuild kits don't always the right springs for the valve body and causes shift issues, so he talked me into the shift corrector kit which I researched and did see what he was saying, so had that done and still no better, still does it, however, it does shift into the gear softer but didn't fix the delay or the hitting hard when it did finally go into 3rd.
After being forced to drive it that way I have since determined that what it happening is it is coming out of 2nd with a second and half pause and then shifting into 3rd, the hard shift comes in to play because during the delay the torque convertor is locking up making it a direct drive like popping the clutch on a standard!!!
I just swapped out the sol pack and I heard from a youtube video that the bolt next to the 2-3 upshift valve on the valve body could be to tight and making a sticky valve, so I re-torqued all the bolts and nuts put all back together and test drive proved to be worse, I now have same issue in all upshifts. all hit hard now, I am at a loss and don't know where to go from here, I can only imaging the sol pack is causing this but I have yet put my org one back in to see... oh and I found two bolts on the accumulator stripped and found one non torqued bolt on the main valve body!!

Tonight I took out my 2013 Elantra for a spin in the ice/snow so see how it handled to see what limitations it had. I came to a stop on a fairly gentle slope that was pretty icy, and the ABS kicked in. It violently pulsed the pedal and made the worst grinding noise. I've never had ABS in any of my cars, but that sound and action seemed like it was breaking something. Is this normal or this car? Or is something wrong that I should have checked out?

When I leave the car in the parking space for a couple of days (in cold weather) and then start driving it, I notice that when I brake I hear noises (like thud.. thud...). Eventually as the engine warms up the noise goes away. I can never reproduce this at the dealer as I have to drive half an hour to the dealer and by that time the noise goes away. Should I be concerned?

I have a 2012 hyundai elantra gls 6speed manual. Every time I apply the brake and turn the car makes a ticking noise that appears to come from the front. It happens when I turn either way. I just had the car inspected, but forgot to mention the noise, and they didn't say anything was wrong with the brakes. It only happens with the brake applied. When I let off the brake the noise stops.

Tonight it was a perfect 72 degrees and I had to run over to a friend's house and pick up my backpack as I didn't feel like riding my bike the ten miles home with that thing on my back. As I usually do when it's nice outside, I opened both front windows and the sunroof and immediately noticed a mid-level pitch grinding noise that comes and goes but is mostly noticeable at low speeds. Initially I thought it was the brakes dragging but it doesn't change with a brake application so I'm guessing it's the front wheel bearings. I'm calling the dealer in the morning to set up a service appointment.

Since around 3 days.. i hear a grinding noise, while going in some kind of streets... highways or not so good roads.. this doesn't happens when I turn the car to left or right, it happens when I am going 30mph+....
Last night I checked rear shocks.. and one of them seems to have some oil leakage I am not really sure, but it has... some wet lines above it.. so I guess that's oil...
Dealership tested the car around 15 days ago, but this weird noise wasn't present.. although they order new rear shock and springs...

My car has developed some intermittent noise but I can't pinpoint the exact source, though it seems to be coming from the front. I hear it in 1st gear when accelerating, and it's more audible if I have my windows down. A faint metallic grinding/friction/rotating noise is how I think I could most accurately describe it. I do have an oil change coming up in the next few weeks and will mention it then.

All of a sudden my fuel consumption dropped from 28mpg as read from the computer display in the dash, to 21mpg. This was not a gradual drop, it was at 28mpg one day and 21mpg the next day. There is no service light on, do these cars produce codes that don't trigger the service light?
A few months ago the vehicle was getting stuck in various gears and lunging, this was from battery corrosion dripping down and eating away at the transaxle range sensor. I cleaned up the battery and replaced the range sensor and the vehicle was driveable again. It re-learned the shift timing and seemed to be ok, then about a month ago it seemed to be forgetting the learned shift positions after sitting over night, I replaced the battery, thinking it was in a marginal state where it would forget the program while sitting. The shifting is still hard sometimes but this seems to have worked but, now my mileage is horrible.
I thought I'd just change out the oxygen and air flow sensors but, then looked at how much they cost now, and realized this would be some costly trial and error. Is there a methodical way to troubleshoot this issue, any way to pull the sensors and measure them?

I have a 2013 Elantra. There is a rubbing type noise in the driver front when braking and turning right. It only rubs(catches) in one spot. Almost like a pulsation, however doesn't pulsate. Hard to describe. Has a new wheel bearing. There are new pads and rotors (two sets of rotors). Took to my Hyundai dealer today. They can't find anything visible. They said only option is to start adjusting/replacing parts as trial and error.

I hadn't driven my car for nearly a month and when I returned I noticed a rather loud "clunking" noise when moving the A/T out of park. The sound is coming from the steering column and is quite pronounced. Is it normal?
I am also hearing a sound something like a bad wheel-bearing while accelerating that I never heard before. It sounds like it's coming from the front end of the car.

When I start my car I hear this very loud noise. I think it is coming from the exhaust but not sure. This only happens when the car is cold(not weather) and after a few minutes the noise is gone. I have aftermarket lowering springs on the car, do you think that caused the problem?(I'm thinking no)...
