The contact owns a 2024 Kia K5. The contact stated while driving 80 MPH, the vehicle lost motive power. The contact stated that several unknown warning lights were illuminated.

The failure mileage was approximately 12,780.
I was driving on the expressway and the engine made a noise and I lost power. I was in the left lane of the expressway. I did not have any warning lights or signs or symptoms prior to this incident. No oil ever leaked prior to this incident. When it occurred, oil was pouring out of the engine all over the ground. The engine was smoking. And a warning message came across the entertainment screen that said, “A possible condition with your engine control system has been detected, recommend service soon” I never received any notification of any oil pressure loss, oil loss, warning lights, nothing. My car has been at the dealership for over 60 days, and KIA is refusing to cover the engine under warranty, blaming an oil change place that did an oil change over a month prior to this incident, and I drive 100 to 200 miles per day for work, so this would have occurred sooner.

While driving in a utility work area on 5/3/24, there was a worker placing cones to redirect traffic. Since he was very close to the travel lane, I proceeded very slowly While placing a cone, the worker got to within a few inches of the passenger side of my vehicle. This set off a warning in my car that something (or someone) was very close. After exiting the work area, I tried to accelerate, but I was unable to. I estimate the car was going no more than 5 mph. Fortunately, there was no car behind me or coming toward me, and I was able to turn left into a shopping center parking lot. It was then that I noticed a warning on the touch screen display that read: "Engine Management System - Details". When I went to look at details, it gave me some warnings but I don't recall what they were. Unfortunately, I did not get a screenshot of the messages. I tried turning off the engine several times, but there was no change. I called the dealer where I purchased the car in December 2023, but he was unable to provide any help without physically looking at the car. Since the dealer was about 40 miles away, that wasn't an option. He did however, provide me with a number to call for emergency roadside assistance from KIA. After about ten minutes, the car restarted without any issues. If this would have occurred while driving at higher speeds, it would have been extremely dangerous, most liking causing an accident.
At 2500 miles when checking my oil I discovered flakes of metal on the dipstick. I immediately changed the oil and in doing so found a massive amounts of metal in the filter housing. I took it to the dealer along with pictures and told them on startup the engine was noisy and sounded like it was low on oil, noisy on acceleration and would exabit an engine knock at times when hot. They didn't investigate it at all. Being an auto tech all my life, I know that metal flakes are a sigh of a damaged bearing and by the sound, a conrod bearing. I'm afraid to take it anywhere other than local commutes. This sounds like the same thing as the K4 Tuscan issue in my professional opinion.
