2 Engine Shut Off Without Warning problem

Failure Date: 11/16/2020

I was driving to work one morning just got on the freeway and my kia Optima with 107k miles decided to shut off out of knowhere. I decided to check the oil and noticed it was pretty much empty when it shouldnt have been. I check it regularly and keep it in good shape also had it changed a month or so back. I had it towed to my mechanic because it would not start at all. It took them 2 weeks and various test including a compression test and installing new spark plugs. After almost 700$ spent they got it running for 15mins and the car shutoff again. They told me it needs a whole new engine. . . So after I get it towed all the way back home I hear that kia has a massive settlement going on for thier engines failing. Not sure if I will get a recall but I have my fingers crossed. I hope that anyone has this problem can find a way to solve this. Not to mention I just payed it off and it forced me to purchase another vehicle.

12 Engine Shut Off Without Warning problem

Failure Date: 09/05/2016

Car has been maintained with regular oil changes every 3 to 5000 miles. Car was not giving any issues until two days ago when the engin shut off while driving. We restarted it and it was knocking loudly, sputtering and squealing. We towed it to a kia dealer the following morning who ran diagnostics and said the engine is blown and full of sludge. They won't honor the warranty since we can't provide every single oil change receipt since the day we purchased the car. We did provide what we could as we lived in a few states with the car and didn't always use the same shop. The car was in motion when the vehicle just completely shut off without and warning lights.

14 Engine Shut Off Without Warning problem

Failure Date: 04/15/2016

Driving the vehicle through an intersection at approximately 45 mph and engine just shut down/off. Thankfully, we were able to pull to the side of the road. Had the vehicle towed to a kia dealership. Service dept had the vehicle for 2 days and weren't able to diagnose the cause or problem but notified me that I had metal shavings in the engine. They changed all fluids and reset the computer, so the vehicle would run, but when they test drove the vehicle, the tech said it still wasn't running smoothly. They said we needed a new engine for $7000, or else we could just drive the vehicle until it quit running. We drove the vehicle for about another 100 miles while trying to decide whether to repair or replace, and vehicle seemed to be running fine but then suddenly shut down again. We had purchased the 100,000 mile warranty, and vehicle was at 110,000 miles. We were able to show routine maintenance and oil changes. After researching, we realized that these are the same engines and same "metal shaving" problems that were found in the Hyundai sonatas, and Hyundai has issued a recall for vehicles under 10 yrs/120,000miles. Kia is having same problems from the online comments/reviews, but they haven't issued any recalls.
