Engine began making a engine knocking noise that became worse over three days (originally mistaken for bad gas but became much louder than that would be). While driving along a busy state road (nc 98) and car choked twice with a loud thump and I feared it would stall. Pulled over, shut vehicle off. Smoke was coming from engine compartment. No actual flames detected. Towed to dealer. Dealer described holes in the engine. Consulted Hyundai and they will only offer a short block replacement. Labor costs are approximately $2500 which I am required to pay. Vehicle has approximately 141k miles. Tow truck operator also told me to research the recalls on this vehicle but this vehicle was not listed but should be. It would appear that the recall was incomplete and should have been broader.

While driving home, I heard a muffled knocking noise coming from engine when accelerating. At the next traffic light, I waited for the light to change, and when I started moving I realized the engine did not start from the hybrid. As I dangerously maneuvered the car across the right lane, I was able to pull over to a safe spot and the warning chime came on saying I had low voltage in hybrid battery. Had car towed home and then to hyudai dealer. They notified me that the engine was seized due to poor maintenance, which was ridiculous. Oil has always been changed by me or a regular garage. After viewing other comments by people who had the same exact problem I realized that this was apparently an ongoing problem with the Sonata Hybrid engine. Still trying to get dealer to replace engine.

While driving down the highway at 55mph the engine was ticking and made a large bang sound and stopped getting any power. I was not braking or turning it smelled like something was burning. I had several vehicles behind me when this happened once I got the car pulled off the road it would not move at all. Now it will not start at all. Lights on in car are engine light and low battery light for hybrid. When trying to start it dings loudly and you can hear the hybrid battery try to start but engine will not even roll over at all. This happened while I was driving down the road.

Engine started making a very loud knocking sound while driving 70-75 mph. Shortly there after the engine stopped and smoke came out of the hood. Towed the vehicle to a local Hyundai dealership that said the piston broke and went through the firewall.

My husband and I were driving on interstate 81 south near woodstock, va on Sunday morning, June 24, 2018. The car began making a knocking sound, then we lost power. By the time we were able to pull over, the engine was on fire. The entire car ended up burning. The va state police, vdot, and fire department responded and I-81 south was shut down for a time. I purchased my car new and did all required maintenance per factory recommendation including oil changes, tire rotations, etc. By the Hyundai dealer in bowie, MD. I have copies of all my receipts from the dealer and they have the records on their computer system. My car had 91,000 miles on it. We contacted the insurance company and the car is a total loss.

While driving on the highway I noticed a knocking sound radiating from my engine at speeds of 60 mph it the noise increased and then the engine appeared to be failing. My gages where the rmp's reflect where not functioning either. Amongst the engine issue my power steering column is also rattling as if it is loose and steering is become difficult. It is frightening to not feel safe in your own vehicle.

While driving the vehicle on side street we heard a knocking noise. We had our car towed to local mechanic where they diagnosed engine rod failure. Car was well maintained with oil changes. Oil and clean and full when error occurred. No warning lights or check engine light ever alerted. Had vehicle towed to romero Hyundai was purchased. They confirmed diagnosis and advised to call customer care as the vehicle previously had 10 visits to dealership for other failures. Over the last month customer care has not been able to assist.

Driving along the highway when I heard a knocking sound coming from the engine while returning home the sound got louder, then I lost control of the vehicle. I regain some control and pulled over on the side of the road. I realized that all the oil leaked out and there were some metal parts on the road. Took it to the dealer when they told me a rod fell through the engine.

Car had 113,000 miles. Maintenance was up to date. Driving from az to laquinta, CA. Heard a knocking noise. Stopped, çhecked oil, fine, car was cool, no engine lights on. Drove 4 more miles, noise got real loud and car shut down on freeway. Coasted to side , engine light came on and stated do not drive. Called tow truck. Engine was seized. Dealer stated engine was frozen and needed a new short block costing $8,800 including installation. Asked why it froze, why no warning lights, they say they did not know. Left car to go look for a new car and was told by several dealers and people price too high and our car had a recall. Checked on line but it said our car was not recalled, but yet we read the same exact description for recall 132 that our car had done. Trying to find out why are car seized up ((froze) when it was maintained and only had 113,000 miles. Since we are not repairing dealer wants car removed ASAP so we are trying to trade it in tomorrow at Honda dealer. Will not buy another Hyundai.
