Engine Knocking Noise problems of the 2016 Hyundai Sonata

Knocking noise, engine light comes on, oil in where spark plug is, leaks oils and runs out way before next oil change. Car in motion, starts to idle weird and then car shuts off.

To who reads this, thank you first and foremost to take the time to read this. This is a real person, this is my real story. I have been noticing a knocking engine noise for 5 to 6 weeks and then got the NHTSA recall number20v746000 in the mail. I set the soonest appointment with the dealership. The day of the appointment I was advised by andy that it would take 3 to 4 weeks for them to look at my vehicle and run it through Hyundai's recommended diagnosis. Later I called the Hyundai campaign hotline and open case # 18081104. I was told to wait 3 to 5 days for a national representative to get back with me. I called two days later requesting an update and shortly later the dealership called me to inform me my car was ready. Andy said it cleared inspection and I asked if it passed all their tests, I was told yes. This was the same staff member that told me a few steps days prior 3 to 4 weeks. While I was waiting for my vehicle to be brought to me, I overheard the another Hyundai rep saying same story told to me about the length of time to diagnosis. Got the diagnosis (repair) details back to find their inspection concluded taking the vehicle for a 7 mile test drive in the city to observe odd knocking noises. Nothing remotely advised from the manufacturer to dealership. I have their report attached but have no clue what to do at this point. I called back Hyundai campaign hotline again after getting my vehicle back today. I am told I have the same case no. And to wait another 3 to 5 days for another representative to contact me.

I noticed a recall for premature engine damage for some Hyundai models. I have a 2016 Sonata that is experiencing the same warning signs. Abnormal knocking noises from the engine and the oil light will illuminate after adding oil within a few weeks. I've also noticed a burning smell from time to time. The engine light is not on. Before the knocking noise began I would notice hesitation in acceleration every now and then but it wasn't constant. The knocking noise is during driving and even more so when turning. This is my only vehicle and I have taken it in for maintenance when needed but this happened suddenly and I am unable to figure out why. On the recall list is the 2016 Sonata hybrid but with my Sonata being of the same year I am sure it should also be on the recall list since the issues are identical.

Abnormal knocking noise from engine, vehicle was in motion entering a driveway, we believe this has been the issue for the past 6 months and the dealer could never figure out the problem, stated it was the battery we replaced it, still same issue, now the vehicle sounds like a tractor due to the rod bearings.

Driving to airport in car. Just pulled in to freeway after stopping at store 45 mins into drive. My 3016 Sonata hybrid limited started making a knocking sound. My boyfriend who is a mechanic recognized it immediatly. Then suddenly engine made loud noise and parts and oil flew all over behind us from underneath car. He managed to get it off road without us getting hit. Waited 4 hours for tow that was covered by warranties I purchased. Hyundai tried to state that only 2 people could ride in tow truck. So one person (there were 2 adults and a child) would have to wait in middle of nowhere while other 2 went the hour back home with tow truck and then came the hour back. There wasn't a gas station or anything around. The car is in shop waiting to see what warranty says about it needing a new engine. All maintenance was done and was in Hyundai shop 5 weeks prior with abs unit needing replaced. There was no warning light or engine light that alerted us to a possible issue.

The contact owns a 2016 Hyundai Sonata. On several occasions, while driving at an unknown speed, there was an abnormal knocking sound in the engine. The vehicle stalled without warning and was able to restart. The vehicle was taken to werner Hyundai (located at 252 capital cir sw, tallahassee, FL 32304, (850) 575-1000) to be diagnosed, but the mechanic was unable to retrieve a fault code or duplicate the failure. The vehicle was not repaired. The failure was intermittent. The manufacturer was not notified of the failure. The approximate failure mileage was 45,000.
