I have a 2015 Kia Optima never had any problems. Last Sunday it starting rattling from the engine, changed the oil the following Saturday and drove it to see if it made it any better. Within 20 mins the noise in the engine from knocking was so bad, my car was trying to die on me at red lights. Luckily, I was able to make it home. Checked the oil that was just changed and drove maybe 25 mins is full of metal shavings. Called Kia and they are trying to say that because a recall wasn't completed before I owned it that I am not eligible for a engine replacement, even though when i bought this used car from a Kia dealer they should have seen and completed this recall. Now I have a car with a bad engine that I still owe 5K that I can't even drive to trade it in.
Driving down highway car engine shut off. Brakes are vacuum assist so brake pedal was hard and not very responsive while trying to stop car. Engine would not restart having to be towed. No warning lights, no strange noises. Just shut off. Engine possibly siezed. Looking in a kia forum this seems to be a recurring problem. I know there were Engine recalls in previous model years may need to be included for this year as well. Engine oil good, coolant level good.

The car currently has 131,000 miles service has been maintained. On [XXX] the car just stopped running going down the road no check engine or any warning that something was wrong.. I had it towed on Tuesday to a local shop who then told me it needed to go to the Kia dealership which is about 20 miles away-?? I had to have it towed again.. once at the Kia dealership I would told that more than likely it would be covered 100% due to a defect in the engines-??

I never received any information concerning the produce improvement -?? Again it was check for recalls on the https://www.nhtsa.gov/ by myself and also the dealer-?? none was showing and to this day it is not showing..

Drove this 15 Kia Optima on the highway when all of a sudden it lost power and died. There was no lights or symptoms prior to this happening. The vehicle ran as it should up until the other day, the Engine had no codes or lights on in the vehicle.. Then without any signs at all the vehicle stalled and almost caused an accident on the highway and the would not start. Barely made it to the breakdown lane. We had it towed to a shop and We spent some time checking the Kia over to find out the starter had melted. We installed a new starter and now the engine has a very loud knocking sound that was never there before. Based on reading the safety recalls and bulletins on this Kia and issues surrounding this vehicle online, we should meet the criteria for a claim. Can you help me please!!!!
Driving on the highway at 60mph and the engine just shutdown and the car turned off. Fortunately, I was able to get onto the shoulder without incident. No warning lights came on until the engine shutdown. Tried to restart the engine after letting it sit for a few minutes, would not start again. Had the car towed to a local mechanic and they discovered that the engine seized. Hoping the service contract I bought when I bout this car used in November will cover the engine.

I have 3 issues currently going on with my 2015 Kia Optima. The first is the Oil Control Valve. This is supposed to be covered under my extended warranty that I pay for. If I didn't have the extended warranty I would be responsible for putting a new engine in a car with less than 60,000 miles on it. However, it will take time for the adjuster to come out and then to decide if the entire engine should be replaced which would then take even longer. The second issue is the O2 sensor which is part of the exhaust. Apparently in a care with less than 60,000 miles on it it's not unusual in the Kia Optima for this to go bad. Kia knows this is an issue but hasn't done anything about it. Lastly, the Stop Module in the braking system needs to be replaced. After hitting my brakes at a red light the ESC light came on and the brake lights don't go off. It's very dangerous as no one behind me can tell if I'm stopping or not. There was a previous recall for the HEC system which I had fixed. Per that recall brake fluid can leak and cause an electrical issue within the brake system but my Kia dealer service department is telling me it's not related to the original recall. I think it is and I think Kia should make the repair with no charge to me on a car with less than 60,000 miles on it. How does the engine, the exhaust system and the electrical system all go bad at the same exact time? This is unacceptable.
