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.
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.
The contact owns a 2012 Hyundai Sonata Hybrid. While driving 40 mph, the accelerator pedal was depressed, but the vehicle failed to accelerate while making an abnormal knocking noise. The vehicle was taken to a local dealer (folsom lake Hyundai 12530 auto mall cir, folsom, CA 95630), but the cause of the failure could not be determined. The failure recurred. The vehicle was taken to another local dealer (roseville Hyundai 200 n. Sunrise avenue. Roseville, CA 95661) where it was diagnosed that the engine had metal debris and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The VIN was invalid. The failure mileage was approximately 70,000.
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.
