Currently have 85k miles. About 20k miles ago I noticed when I have the driver window down I would hear a rattle coming from under the car when accelerating. Doesn't happen every time but does quite often. Usually goes away almost immediately. I'm not having any other issues and with my warranty out I'm not anxious for a drip to the dealer.
View 3 Repliesjust about a week ago, i've noticed this weird rattle coming from the front end, sounds metallic (maybe something is loose) but it only happens when I accelerate from 0-80km/h, but the sound isn't there if I slowly accelerate. Nothing seems to be wrong with how it runs, its just the sound that sounds horrible, like nails on a chalkboard.
Also, I've noticed the engine ticks really loud when it gets started. However, the sound goes away after a minute of idling.
There is about 19,000 kms on it and I got it in January .. I travel a lot maybe a little too much.. I want to take it in to the dealership, but I'm pretty far from it and would like to know what it could be before I take it anywhere to get fixed.
Took car in for normal service (69,000 miles) and had Tranny Fluid Service completed. When I took the car home I noticed some slight tranny slipping while accelerating up to highway speeds (so assuming 4th to 5th gear, maybe 5th to 6th). Took it back to the dealer and after a week it had a new transmission. Took it home and it slipped again, also only accelerating to highway speeds. Took it back and they told me they reset the computer that monitors my driving patterns. OK, not exactly sure what that means. So, now driving to work this morning it slipped (or maybe hesitated is a better word) again when accelerating from about 55 mph to 60 or so. Car has never had issues like this before, gas mileage is still in the 30 mpg range.
View 9 RepliesSuspension noise I am getting from my 2011 MD.
This noise occurs only over small shock type bumps IE, train tracks that are not smooth, those reflectors in the road, and the metal plates over construction projects. Any bump that forces the suspension over a small vertical or near vertical drop or rise of about one inch.
In my driveway I have a storm grate about an inch lower than the surrounding pavement and it rattles over this every day. Now the fun part.
The noise is ONLY when I hit such a bump with the right side of the car. The left side rolls over the same bumps smoothly and quietly.
This noise is also only present over the small type bumps discussed earlier. My dealer has a rough road that they use to test suspension noises and the car rolls down it silently. The problem also doesn't manifest itself over speed bumps.
The noise is still present while applying the brakes on which makes me doubt its a caliper float issue.
The strut brace and lower control arm/bushings on the right side have been replaced by the dealer under warranty but they can not seem to get to the root of this problem as both these replacements have had no effect.
From inside the car it is very difficult to pinpoint where the noise is coming from but it almost seems like the center of from suspension.
I drive a 2011 Elantra and like it quite a lot with the way it looks, interior space, beautiful lighting, fuel economy, etc.
I started hearing rattle while driving over even slight bumps; the sound seems to be coming from both of the upper halves of the B-pillars. Tried spraying plastic contact surfaces with silicon spray but squeaks are still there.
Simple inspection of the upper part of the B-pillar plastic (gray colored, in my case) shows that it has a significant gap between the plastic cover and the pillar...
So now I'm thinking to remove the plastic covers and see what may be at fault, to tighten the way it sits maybe. How to go about taking the thing apart (and then putting it back in place )?
I have been noticing a rattle noise coming from the a/c vent with the setting on the lowest. What this may be?
View 4 RepliesI'm having a strange problem with my 2011 Elantra. Twice this month, I've gotten up in the morning and the hazard lights are on. The first time, I thought it was the parking lights and I'd left the door ajar but I went out and checked all entry points and everything was secure, so I checked interior lights and everything was off so I started the car, all good and when I turned it off, the lights went out but an hour later when I went out to leave for work, car barely started.
Since that time, I've paid attention to the lights. They are always off when I leave the car. This morning, lights are on again. Nothing will turn them off except for starting the car. I'm afraid that the repetitive drain on my battery will soon kill it.
So lately I've been hearing what sounds like a slight lifter knock that develops at 1500 rpm to 2700 (I have ultragauge) when accelerating or maintain speed, and it only appears when the engine is at operating temp and disappears when rpm is below 1500 rpm and above 2500 rpm my oil is running at 3900 miles using Toyota synt 0W-20 and it looks pretty clean and at high mark of the dip stick.
View 3 RepliesI recently purchase a 2011 Sonata. It sounds like there is a rattle in acceleration coming from the exhaust (passenger rear)
I had the just alignment professionally checked, and it's spot on, but it seems to pull to the left still.
I have had a rattle that lasts 2 seconds on my 2012 Elantra for the since about 2 oil changes ago. The car has 152,000 miles on it and I've changed the oil regularly per the maintenance schedule, although not always with a Hyundai filter.
I'm strongly suspecting that this is the timing chain tensioner, but I could be wrong. Other than this, the car runs fine. I tried having the oil changed by the Hyundai dealer with the OEM oil filter and the problem appears to be a little worse. It first started to appear on cold start up after the car sat for >8 hrs or so. Now, it appears on cold start up >2 hrs. I noticed that the dealer put 5W20 in it.
I'm wondering if lower viscosity oil makes the problem worse during hot weather. It seems when the weather is colder it takes longer for it to appear. I'm wondering what my options are here. I really don't know how much $$ it is to go after the tensioner and how critical it is - the dealer said they do replace them and that doesn't always fix the problem though I'm not sure what he meant. I have read a few other posts about tensioners here, but I'm also wondering if this is an issue with the new engine.
I am the proud owner of a 2011 Hyundai Elantra GLS. After I bought this car (used), I have been having an issue with the exhaust. When you first start up the car, it idles and sounds great! But then as you put it in drive, well, that is when, what sounds to me like exhaust, rattle starts. you only hear it when you are on the gas or have a load on the engine (like A/C) at idle. It sounds like it is coming from the sound the left side of the engine (if looking at the engine from under the hood). Is there a way to fix it without taking it to the dealership?
View 10 RepliesMy 2012 Elantra has been nothing but problems. Unfortunately, with me being away from home in the USA, I haven't been able to bring it to my dealership. Lately, I've noticed that the acceleration of my E sounds different with the A/C on. It's more noticeable right when I hit the throttle that the engine engages, and power goes to the wheel. The sound is a deep more drone like sound, and is only there when my A/C is on.
View 8 RepliesWith Eco off my sport has a nice bog/hesitation when accelerating. Doesn't matter if ac is on or not. I'm also using shell from the same station I've always used for years. The 2.0 is still pretty new. My cruze turbo had the same kind of issue and turned out to be the spark plug gap was too small from the factory.
View 1 RepliesMany months ago I had a rattle in my 13 Azera. Of course when I took it back to the dealer they heard it but when I left it was gone. I had a scheduled service to have it looked at but the rattle never came back.
The last two weeks it is back louder than before. I thought it might be coming from the passenger seat belt housing on the side of the door but now it sounds like it might be coming from the passage side rear door or maybe the sun roof. Hard to tell yet my girlfriend was in the car last night said it wasn't coming from the passenger side seat belt housing sounded more like the rear of the car.
So going to make an appointment to get it looked at next week. I hate rattles! I looked all over the car yesterday after had her cleaned up. My trunk is empty, so not sure what it could be.
Experienced an occasional (not always) rattle in the passenger rear area of the 2012 Elantra GLS. I have a video on YouTube of this specific rattle that I will post eventually, it says i have to wait a few days until I can post links on here.
View 22 RepliesI have a rattle in the dash up in the middle of the dash kind of in between the two sides of the car and between the window and front so basically right in the middle of the dash, if I slap it with my hand I can make the same sort of rattle so something is loose, bad thing is I dropped by dealership and it didn't do it when I was in the car driving with the service guy but I slapped on the dash and you could here a something loose sound rattle same kind I hear when driving. He said that is normal for things to make noise in there when you tap the dash. About a week ago I had the dirty sock smell coming from my vents so I took out the Cabin Filter and sprayed Lysol in the intake the put a new filter in. This is about the same time the rattle started. I wonder if the Lysol might have made something come loose in the vent system.
View 3 RepliesExperience with rattling coming from the rear/trunk area. My 2013 1500km new limited with Nav have developed a very bad rattle coming from the back.
I have tried removing the rear deck and no luck, There are now nothing in the trunk except for my spare tire kit. the rattle gets louder when I fold down the rear seat. The rattle seems worse and more frequent when the car is between 10 to 60 km/s...
So I've noticed this alarming engine rattle when I first start car as if there is no oil? It only lasts a few seconds! Was it diagnosed with Hyundai? Maybe a quirk of the motor, but seems like over time would cause excessive wear on engine?
View 14 RepliesMy 2012 Elantra has 16k+ mi. on it and recently I've noticed a noise while accelerating. It typically occurs when first accelerating between 1st and 3rd. The sound itself is hard to describe as I am not a professional so it's hard to find the right words to give an accurate description. It sounds like something rubbing together or perhaps something loose. Any insight into possible causes for strange noises while accelerating on a car this young? It doesn't happen every time, typically when first beginning the drive and occasionally when beginning from a dead stop at a light.
View 19 RepliesI have a 2015 Hyundai Elantra Limited. Lately, the check Engine light comes on when I accelerate from a full stop and stays on for 3-5 seconds. It has also happened when I accelerate to get on the interstate (that just started today). There is no issue with the car accelerating. Everything else seems to be fine. It's just the Check Engine light that is freaking me out a bit. I've had the car since June so I'm not ready for any major issues. It started two days ago. I took the gas cap off and put it back on last night to see if that was the cause but it's still happening today.
View 2 RepliesWhile driving, the TCS light will flash and the car stops accelerating. Dry pavement, no bumps. I have to pull over to the side of the road, and shut the car off and restart, or wait a few minutes for it to stop having a fit.
I really don't feel save driving this car due to this issue. Is there a specific sensor that can be changed out or is this tied into the ABS and possibly individual wheel sensors.
