I was on the expressway and car hesitated and jerked while speed began to increase followed by hybrid warning system alert. (Pull over and stop the vehicle) with a flashing ready light. Could have caused a major accident with loss of life as there was no place to safely pull over. Warning lights came in immediately after the cat jerked.

I was on the highway during rush hour when the car was rattling during acceleration. I was going around 75mph. The car just died in the middle of traffic and I coasted to the berm. Once stopped, it smelled like something was burning and I had my 2 small children in the back in 5 point harnesses. They couldn't unbuckle themselves and I could not get the back door to unlock with the key fob to get into the back seat to help them. Once they were able to loosen their buckles, they had to crawl through the front seat to get out. Had the car actually caught on fire, I wouldn't have been able to get my children out in time. This was the absolute scariest ordeal I've ever been in. One shop has said the engine has seized. It's now sitting at Hyundai waiting for them to look at it. No warning lights came on until the car died.

When arriving at a stop and then making a turn on a street vehicle came to a halt. It would not turn on again. The vehicle was able to be pushed to the side, and started to have a knocking sound from the engine, after vehicle was started. Searching thru the internet found recall campaign 312, that has same issues I experienced. Vehicle is drivable but has loud knocking sound as the speed goes up. Also, vehicle was purchased with a rebuilt title and is road worthiness.

I brought my engine in to be checked after the recall for engine failure. Hyundai told me it was fine/not affected. I brought my vehicle in twice after that because while driving, the engine suddenly stopped accelerating in the middle of driving. Both times, I was told that nothing was wrong with my car. They went so far as to accuse me of overfilling my gas tank (which I have never done). I trusted them instead of looking up this issue being part of the recall symptoms. Finally, while in the middle of driving, the engine locked up completely. I had it towed to Hyundai. They finally admitted it was covered under warranty, but I see no evidence of them recording it as a vehicle affected by recall. I am very concerned about this because there are probably thousands of other families at risk right now because of Hyundai's dishonesty and dodging responsibility and not including their VINs in the recall either. If their engines were to lock during a left turn for example, people are at risk of dying. In addition, Hyundai has still not reimbursed me for the towing and rental car costs of $2918.27 total which they are entitled to per the settlement. It has been over 3 months since I turned in the last of the paperwork. It has been over 7 months since the engine died. More importantly, they need to be fully investigated for withholding information, falsifying information, and putting people at risk of death and at a financial disadvantage.

The knock sensor kept going off and check Engine light would be activated, we have taken to several auto places and check engine light and codes would be cleared, engine seized and no longer works we were stranded on side of road. Our understanding that this is part of the rod bearing inspection recall campaign. We purchased car for our daughter and it has a salvaged title, we were told by Hyundai dealer that due to it being a salvaged title they can't do anything. My understanding that any recall must be honored with or without salvaged title, is that correct?

I gave my son this car b/c I thought it was safe and reliable. My son was driving down the road and all of a sudden the lights started blinking and he pulled over. He had to have it towed and repair shop says the engine is locking up and would cost more to replace. This is a paid for car and now we are totally screwed. I really want the manufacturer to honor and fix their issues. I ensured I had this car serviced timely and took care of the car. Now, I am $12K in the whole and will probably go ahead and trade in my other 2017 Hyundai Sonata to avoid anymore of these issues that no one can honor to fix. This car has about 80K miles on it so not too bad, either!

Connecting rod broke and punctured engine. Vehicle is available for inspection. My son was driving vehicle and the vehicle shut off while driving which could have been very catostrophic. Service center is who advised what the problem was after the vehicle was towed to their facility. Not inspected by any others at this point. Vehicle was just in for maintenance a week prior. No warning lamps or symptoms until the moment it happened. Approaching stop sign heard knocking or clicking noise, proceeded to side street to pull over and before he could pull over, the vehicle completely shut down. He went to look under hood and oil was splattered on top of hood and leaking all under vehicle. Vehicle was then towed to service facility who advised the connecting rod broke off and blew hole in engine.

- Milwaukee, WI, USA

My car started making knocking noise while I was driving. I put my VIN on a website and it said my car was affected for recall engine connecting rod bearing and qualified to get fixed under campaign. On 4/04/22 I had my 2012 Hyundai Sonata towed to the dealership where few days later they denied it because of salvage title. I contacted Better Business Bureau for help and almost two months later denied me and closed my case for the same reason it has salvage title. My car does not have 100,000 mileage and only is not operating because of this mistake the Hyundai manufacturer made. The BBB auto line sent me the car fax and none of the previous owners ever got this recall fixed and now that I have the car it stopped working because of the rod bearings and the dealership has confirmed it. It is a safety concern and is not performing as it should because of manufacturer. I have the proof where it says my car is affected. It having salvage title isn-€™t valid reason to refuse recall coverage. Consumer is trying to get the car fix under the engine connecting rod bearing campaign.
