Sonata I45 (YF - 2011+) :: Faint Knocking Noise When In Reverse

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?

Sonata I45 (YF - 2011+) :: Knocking / Shudder While Accelerate From Cruising?

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?

Sonata I45 (YF - 2011+) :: Repetitive Knocking Sound From Engine

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?

Sonata I45 (YF - 2011+) :: Transmission - Valve Knocking Noise From Engine Zone

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.

Sonata I45 (YF - 2011+) :: 2013 - Humming Noise From Engine When Accelerate Or Car Decelerates

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 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.

Sonata NF (2006-10) :: When Turn The Key Engine Does Not Start / Faint Click

I am having problems with starting my 06 sonata. When I put the key in the ignition there is power, but when I turn the key the engine does not start. There is a faint click. This seems intermittent as most times the car starts normally. The battery shouldn't be the problem as I replaced it not long ago.

Sonata I45 (YF - 2011+) :: Glove Box Rattle And Knocking Noise (when Reversing)

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.

Sonata I45 (YF - 2011+) :: Stalling When Putting Car In Reverse / Loose Knocking Noise

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?

Sonata I45 (YF - 2011+) :: Vibration Rattle When Accelerate Or Decelerate Through 1500 - 1700 RPM

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.

Sonata NF (2006-10) :: 2007 - Faint Engine Tick / Click Sound When Accelerating At Speed

I have been experiencing a slight issue with my 07 Sonata V6 lately. When I am accelerating, most commonly when already at speed around 80 to 90 km/h, I would hear this 2-3 ticks / clicks when I press lightly or moderately on the accelerator pedal. The car would accelerate fine without any further noises. When I release the pedal, the car slows down a bit, and I press on the pedal again, then the same sound re-appears.

Volvo - 740 :: 1992 - Loud Knocking Or Clicking Noise Directly From Engine When Accelerate

My Dads 92 Volvo's engine is making a knocking noise and I'm wondering what the possible causes are. He doesn't take that great care of it but it didn't over heat or anything. It sounds like it is making a loud knocking or clicking noise directly from the engine when you accelerate. It still runs but definitely has a lack of power.
