Sonata I45 (YF - 2011+) :: Knocking / Shudder While Accelerate From Cruising?
Aug 19, 2013
I just had my 15000 check-up for Sonata 2011 a week ago, everything went fine. The issue I am currently having is that I notice that when I drive on the freeway, after cruising for a distance and then stepping on accelerator to speed up, there is occasionally a knocking or shudder that occurs initially and then goes away. This seems to be reproducible if I accelerate, then let the car cruise, then accelerate again. But it does not happen every single time. I haven't noticed it too much on city streets.
My question is what may be causing it. If I were to take it back to the dealer, how much will I be charged for the inspection and if they were to find nothing wrong. Additionally, should I take it to the same dealer (which is about 20mi away), or a closer one?

I notice some faint knocking from the engine when I accelerate. I notice this symptom during summer months.
What to do? 2012 2.4l engine ...

This is a intermittent issue. While either parked but mostly at stop lights I'll notice the engine shudder and shake very hard. It's done it about a handful of times and sometimes the AC is on and sometimes it isn't.
I have a 2011 SE ...

My car has developed a strange engine/transmission shudder that occurs only between the temps of 32-50F. It happens when the car is still warming up, when I pull up to a red light and put my foot on the brake pedal the front end makes a vibrating/shuddering noise. You can only hear it from the inside, it sounds like something under the hood or maybe dash is vibrating.
If I shift into neutral or park it goes away. It looks like the RPM drops in drive, but it won't happen when the car is warmed up or if its colder (20F) or warmer out (50F). I recently installed a front strut bar, but I'm not sure it's responsible for causing the vibration I'm hearing.
I checked the oil level this morning, it's right at the full mark. I might try some injector cleaner but it's worth noting Hyundai recommends frequent spark plug replacement in these engines. I believe the manual states to change the spark plugs at 45K, more frequently if the car idles or is driven at slow speeds. I've also seen the 2011 manual indicate to change the plugs out at 22.5K.

I picked up my 2012 limited Turbo last night but noticed there's a rattle of some sort when I accelerate around 2k rpm, it kind of sounds like a bunch of metals being shaken up. Is this normal? I am also trying to test for the left/right pull, but with all the bad roads here in the city its getting kinda tough.

Noticed while standing still there is a knocking when I turn the wheel. Also hear a know when driving and I hit bumps. mostly noticeable when going slow.
I'm at 104,000 kms and my mechanic says the rack and pinion is toast. I've never had to replace this on any car.

I just purchased a 2011 Hyundai Sonata with 126K miles on it and so far it has been okay. The only thing I noticed is a whining noise when I go to accelerate and the other day I went to put the car into reverse on the odometer it did not display what gear I was in nor did it illuminate on the gear shift whether I was in drive or not.

I have a 2011 Sonata. Recently, I have heard a faint knocking sound when I'm in reverse. It doesn't do it all the time. When I took it into the dealer, it would not make the sound while there. What causes that sound?

I've got a 2011 Sonata GLS with 83k on it.
Last night I was driving and started to hear a repetitive knocking sound. Stopped to determine if it was only when moving but it continued in park.
Checked the oil and apparently there was very little of it.
Don't know how I screwed that up but the mechanic heard the engine for 1 second and said I need a full engine replacement.
So, yeah I am ticked off and need to take care of it.
The VIN qualifies for a replacement under the recall but I don't know how the dealership will feel about the present engine condition.
If that's not an option, where do I even begin to look for a replacement?

I bought a 2011 Sonata (GLS 4dr Sedan with the 2.4L 198hp engine). Till now i got a lot of issuses like the knocking in the steering gear column etc but i fixed all by myself. Now i am looking for a new or used but in a good condition oem exhaust. Because always I am revving really light from 1000rpm to 15000rpm I am hearing a loud rattling sound. Like something in the exhaust is not fixed and is vibrating out of that thing.

I drive a '11 Sonata GLS and experience the rattling noise/clanking when weight shifts to the front-right of the car or when i go over a dip, and the noise is coming from the passenger side of the vehicle. I THINK it is the glove box issue that has been mentioned before and I am going to purchase some felt tape and apply this method [URL] .... that was posted here. Did this correct the issue?
And also when i reverse the car (specifically when I turn the wheel to the right) I get a knocking noise, which seems to also be coming from the front-right (or back) I can't tell. Can this be an axle? I'm at 79k mileage so the dealership wants $125 to diagnose the problem and that amount will go towards anything needing repair. Should I take the car to another shop instead?

My car shifted wrong (i don't know how since it is automatic) and heard a loud knocking noises and lost power and then she shut down and turned off. called Hyundai assurance and they towed it to the nearest dealership since my dealership is an hour and a half away from my school. I don't know how this happened. I tried to crank it back up. heard a loud squeal maybe water pump? and she turns on but the rpms wouldn't go past 500 rpms well there she goes.

I have a 2011 Sonata GLS with 127k miles on it and I'm trying to diagnose a problem, possibly with transmission.
Since I bought the car at 115k miles I started hearing a noise from engine zone, which appears quite rarely. Noise resembles valve knocking, appears mostly at traffic lights and colder weather (evenings). I was trying to catch the sound by recording it while using emergency brake at D pos. but the sound disappeared right after releasing brake pedal.
Describing in a different way it sounds like a propeller touching something with its blades. The sound also appears at 1900rpm on any gear (mostly when slightly releasing gas pedal around 2k rpm).
While trying to understand/fix the issue I used:
- liqui moly valve cleaner and engine flush
- techtron injection cleaner
- replaced spark plugs
These operations had almost 0 effect on car behavior. The symptoms boil down to a torque converter. Transmission shifts fine, I was going to try transmission fluid change ( a full change by dealer), however it may do more harm, so I'm not sure yet.

Vehicle: 2013 Hyundai GLS @ 36k miles.
When my vehicle is stopped or in motion at low speed, if I turn the steering wheel, I hear a knocking out at the sound towards the front of the vehicle. How concern should I be?

I drive a 2011 Hyundai Sonata GLS and it has about 84,000 miles on it. Sometimes in the morning the car will not start and I have to start it in reverse... Often times the check engine light will come on and stay on and other times it will go out. Sometimes when I am putting the car in reverse it stalls out... Then there is this horrible loose knocking noise that I think it coming from the steering wheel... Is this car about to put me down?

I have 2011 Sonata Limited 2.4L I have a rattle that seems to come from the engine compartment near/thru the dash/driver area. I am getting pretty good at replicating the issue. When I accelerate or decelerate thru 1500 - 1700 rpm the rattel/vibration happens. If I can continue to keep the same rpm level the rattle remains. It tends to be even more frequent when the AC is on. I have had the dealer look at 2-3 times and they cannot seem to remedy the problem.

New Sonata GL owner. Just picked it up last week and I love the car. Great drive, great features. Only thing is I am noticing that there's a humming noise from the engine whenever I accelerate and when the car decelerates. It's not really noticeable during the day when the streets are busy and I'm listening to the radio etc., but at night when I'm driving on quiet streets its quite audible and it almost sounds like Diesel engine.
I read a few threads on this and people have attributed it to the direct fuel injection - is this humming sound normal? Do all sonatas sound like this? Or should I go back to the dealership and get it checked out?

I got my Sonata at 27k, its now at 76k and the cars been great although I had the following issues.
I've noticed sometimes when I startup and shift into reverse the car jerks a bit and its not a smooth transition. However other times the car is very fluid in switching gears. Should I take it in to have a look at it?
Also when I am turning onto a unleveled road (usually a higher road), I notice a creaking/knocking noise coming from the front of the car, also notice it when I reverse into a parking space sometimes.

Every time when i accelerate, there is a 'blade spinning sound' coming out from the engine, i noticed it when my car hit around 5k miles, now it's about 7300 miles. any idea what that is? could be the belt problem?
The second noise is a constant 'locking' sound comes from back passenger side. when I locked all doors, (especially in quiet night makes noticeable) about every 10 minus, the door kept making a 'locking' sound, it sounds the latch and the lock can't fully attached each other, and the door has to constantly reboot the auto-lock system.
What are the issues of these two annoying sounds?

I recently purchased a 2013 forester and noticed a slight shudder in the car once I start to accelerate but it only lasts until I hit 20mph or so then disappears. The salesman tried telling me it was a normal subaru characteristic and being new to AWD and subaru I was a suckered and listened to him but after owning the car for a week it's more noticeable than when I first drove the car off the lot. I'm not sure if its the tires out of balance or my half shafts or possibly drive shafts are screwy.
