Purchased car used on 10/24/18. "catastrophic engine failure" occurred 53 days after purchase. Entering highway, accelerated above 45mph, had trouble changing shifts (automatic), "sputtering" sound from the engine and could no longer accelerate, engine cut off suddenly, all dash lights came on. Was able to coast safely to the shoulder. Was not able to turn engine back on. Took to auto shop - was first told it was a bad starter, starter was replaced but still not fixed. Next diagnosis: it was a bad battery, battery was replaced but still not fixed. Next diagnosis: bad wiring from battery to starter but still not fixed. More investigating by auto shop and reported that timing chain was presumed broken and caused engine to "lock up". "engine rebuild" not recommended, but 2.4l engines are no longer manufactured, the only option is to get a used one. My mileage was 86,722 at time of incident.

Driving on the on ramp of interstate and it cut off. All of the dash lights flashed once then it cut off. I was told by two different auto repair shops that the engine froze. Call dealership and was told that the 2.4l engine was not manufactured anymore. It is sitting at an automotive shop waiting on an engine from a wrecked tucson costing me $6,500 - 7,000 to put in. The car has approx. 159,000 miles also had to replace transmission around 103,000 miles

Sudden loss of acceleration/power while driving car straight through a parking lot. Thank goodness I hadn't made it to the highway! All dash lights came on and car came to rolling stop. Turned car off and when I turned it back on there was a loud rattle in the engine while accelerating. Took it to a mechanic right away and was advised the engine would need replacement (though they did not take it apart to determine exact issue). Issue seems consistent with other complaints about this make/model and in line with the issues from the recent engine recalls on sante fe and sonata models. Car only has 82k miles and is now complete junk. Hyundai won't help.

I was driving the vehicle on the garden state parkway at approximately 70 MPH. I heard a bang come from the engine area and the car lost all power. All warning lights came on and smoke was coming out from front of car. I coasted to the shoulder. Fortunately this was early sunday morning with very little traffic on the highway. T could have been rear ended. I got out of car and noticed a puddle of oil under the car. I had the car towed home. The engine has failed. The car had regular oil changes with synthetic oil. 104k mileage. This car uses the 2.4 theta engine. After researching the failure, I have found this is the same engine used in the sonata and kia sportage that also have a problem with engine failures.
