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+) :: Engine Damaged - Metallic Pop Sound While Driving

I own a 2011 Hyundai Sonata with ~40,000 miles (certified pre-owned). I heard a metallic pop sound while driving but did not see anything on the road or in the rear view mirror. Then I got on a highway and couple of minutes later there was no response from the engine (i could feel the car decelerating). Then the engine started responding again. A couple minutes later, again there was reduced response but this time I got a bunch of lights (oil pressure, abs and a few others). I pulled over and tuned off the car. by this time only the oil pressure light was on.

I checked the oil which was near empty. I walked to a nearby gas station and bought oil and filled 2 quarts. Then I noticed that all oil was draining right through in a steady stream.

I had the car towed to a nearby Hyundai dealer. The dealer diagnosis was that there is no drain plug which may be because the last place the oil was changed (around 2-3 months back) did not install the plug properly. He also said that the engine is ruined and will have to be replace and asked me to contact my insurance company.

The last oil change was also done at a Hyundai dealer (a different one than the one that provided diagnosis). I checked my driveway and there are some oil stains, I haven't driven the car much recently and have recently moved into this place so am not sure if these are new or old. What are my options. I don't have the the thousands required for a new engine.

Sonata I45 (YF - 2011+) :: Engine Shaking When Driving Uphill / Tachometer Immediately Goes To Zero

Been trying to save my miles on my 2011 GLS because I'm right at 100k (99.2K to be exact) and had a feeling something would be going wrong soon. Already had short block replacement, both CV axles replaced, steering columns, seized calipers, transmission sensors, and other repairs all done under warranty work for this stinker.

Driving to work today hear a clunk as I am driving uphill, tachometer immediately goes to zero, engine begins violently shaking, and traction control light comes on for some reason. Had my OBD scanner already plugged in and it pulls P0336 code for a crankshaft position sensor. Fortunately was close enough to home so that I drove it back and took the train to work. Probably going to take it to dealership tonight. The clunk and violent idle leads me to believe its more than a sensor problem. Car has had issues shifting over past month, but was so sporadic and not able to ever be replicated. Would maybe have a hard shift once every 2 weeks. That's about it.

Sonata I45 (YF - 2011+) :: While Driving Heard A Rattling Noise - Engine Cuts Off

Tonight while driving I heard a rattling noise under the engine, come to a stop and the engine cuts off. I pop the hood, get a jump and nothing. So I check the oil and it is dry... I changed it 4 months ago myself, it is a mystery how it leaked. No light came on, no oil leaks anywhere..

Is there any hope in having the engine turn over again? If so how should I go about trying to turn it? Engine only has 61000 miles on it.

Sonata I45 (YF - 2011+) :: 2012 - Stopped While Driving And Won't Start - Replace Engine?

for the last 5 months, i have not been able to use my 2012 sonata which broke down in October last year and has since been in the dealership in Dubai and they have never taken any action. what happened is that the car just stopped when I was driving at normal highway speed. no indication, warning or anything came up. the car just stopped and did not start any more.
when the car got back to the dealership they called me after a few days and told me that my engine block is completely cracked and the whole engine has to be replaced. I don't understand this, the car was only about 16 moths old and has 23,000km on the odometer. the car was always serviced and never driven erratically. until today no one from Hyundai took any stance to the problem

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+) :: 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.

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...

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+) :: GLS Shifts Hard - Knocking / Creaking Noise On Front Passenger Side

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.

Prius (2010-12) :: 2011 - Engine Knocking At Startup?

Initially thought that this was related to some water in the tank, since it started when the gas dropped to 1 bar (already put some stuff HEET when put the whole tank, did 60miles so far). ODB throws out multiple cylinder misfire (codes 300, 301, 302, 303 etc). It lasts up to 3 seconds. Sometimes the check engine pops up sometimes it doesn't. there was absolutely no problem under load. does it seem like a fairly common problem ? Intake manifold clogged ?
