Engine Knocking Noise problems of the 2015 Hyundai Sonata

I was driving to work at like 4:00 in the morning it was still dark outside the light turned green and as I hit the gas pedal the car stall it was moving slow so on my right hand side there was a building so I try to make it to the parking lot the car started to power down in a knocking noise started it was a busy morning in the morning work traffic.

My car just started making a weird knocking sound and so I pulled over and the car would not start once I turned it off.

The connecting-rod bearings in the engine wore out prematurely. My car only has 75,000 miles on it and does not come up on a VIN search at Hyundai as a recall vehicle even though it has the 1. 6 gamma motor in it. The description from Hyundai of the issue is the following, "abnormal knocking noises from the engine, reduced power or hesitation, illumination of the "check engine" light or the engine oil-pressure warning light; or a burning smell, oil leaks, or smoke. " this is exactly what happened to us when the car died. We took it immediately to our local mechanic who was shocked at how worn the bearing wear and the large amount of metal shavings in the oil.

Was driving about 60 down paved road started hearing knocking noise under engine noise got louder when I tried to push gas because it fealt like I lost power and then suddenly car started vibrating and then turned off. And lost all power. Oil light came on for 1 sec and then turned off the the check engine light came on and then went out and t hen rolled to a stop. Car tried to start but would not start. Had to have it towed to my house because dealer was closed and then towed to dealership 2 days ago still have not heard back from them and I have no car to get back to work. My car has just turned 70,000 miles and should not be going through this.

My car engine was running fine but when I started it the next morning it started shaking real bad. Kind of a knocking noise like a rough idle.

Excessive oil burning knocking sound stalls while driving.

Engine tapping,knocking noise by the pistons Hyundai recall for software upgrade then two months later engine went into protection mode max speed only 57 mph so they change knock sensor then 5 days later back to Hyundai with same problem engine running in protection mode with the blinking engine light again this is the third time. Knock sensor worked find the first time because something happen with the knew one. The car was in motion on every case engine is no good.

While driving car on highway heard knocking sound from engine area. Car lost power and then engine stopped working. Safety issue since car will not start again and got stranded on highway at odd hrs.

The vehicle began making a knocking noise while driving up the mountain to big bear. No warning lights illuminated on the dash. Two days later while descending the mountain, the vehicle continued making the noise. No lights were illuminated on the dash. Then, while still on the mountain, there was a loud "pop", smoke could be seen in the rear view mirror, and the engine died; I coasted to the side of the road. The car behind me pulled over and the driver yelled that my car was on fire. Flames could be seen under the car. The fire spread and ultimately the car exploded, setting the hillside on fire. The fire department extinguished the fire and the car was towed away.

While driving on a main road in my city I accelerated and heard a banging noise in my engine, when I accelerated the noise got louder. Finally, the noise stopped and as I noticed the noise gone I also noticed I could no longer hear my engine. I tried to accelerate and my speedometer was completely frozen with the oil light, engine light, and battery light on. I was able to coast to a residential area where my car was picked up and towed. Fast forward a few days and Hyundai is now claiming that the engine failure is due to neglect as now they are requiring all maintenance records for my vehicle or my warranty is null. If I can't get my whole maintenance history then I was told that will be a real problem and my service may be denied! mind you, 2014 Sonatas were recalled due to their engine but I was assured the 2015 Sonatas have a different engine, different part. Please do your research and do not buy a Hyundai, they do not stand by their work.

My engine suddenly stalled while driving down a busy highway with my family. Luckily no one was hurt thank the lord! we were driving down the highway when we started to hear a knocking noise and the car started to decelerate. We noticed there was white smoke as well. I was able to get the car to the shoulder of the highway. The car would not restart so we called roadside assistance and since it was Saturday evening, (after hours) we had park the car at a nearby walmart until Monday. I had to do the whole roadside assistance song and dance all over again Monday. The service department was very accommodating. They were pleasant and even provided a loaner car. They informed me the engine would need to be replaced but since my car only had 34,000 miles it should be covered. They said they just had to get it approved by Hyundai first. After a week of waiting they called me up an told me Hyundai would not be covering the vehicle due lack of maintenance (sighted oil crude build up as evidence) and I would need to fork over $5500. I got the oil changed and maintained the car but failed to keep documentation. Upon researching the issue, it appears Hyundai has a history of not standing by their warranty and leaving their customers high and dry. In fact they just settled a law suit for the same exact thing. So we paid up, waited a week for the repairs and now I'm back up here a week later with another engine problem (overheating). Luckily we only had the car for a week because they likely would've charged me again. Well hopefully they will provide me with a loaner again because this just destroyed my work schedule for today.

Engine performance was reduced; a knocking sound could be heard from the left side of the engine; within a few days the engine stalled while driving and would not restart. Hyundai dealer inspection indicates the engine is seized up. Symptoms are similar to those in engine-recalled Hyundai Sonatas from the previous model year. Hyundai declines to pay to replace the engine, but I suspect this is the same problem as occurred in previous model year, for which Hyundai is replacing engines.
