Engine seized and was smoking. No warning lights on dash until engine siezed and then it was ESC light that came on. Engine started smoking when seized. Checked oil and there was none however we had just had the vehicle in for a state safety inspection 2 weeks prior to this happening. Have had regular oil changes thru dealership and car was scheduled for oil change prior to this incident happening. This year and model of car already has a recall for piston rings overheating and burning oil which causes Engine failure and fire. Warranty claim was denied due to no oil in Engine and Kia doesn't include oil consumption with their warranty. Car is currently at First Team Kia Dealership in Suffolk, VA

The Engine. No? The engine blew up at night in the middle of a busy highway. Leaving the vehicle powerless and overheating. Yes. No, there was no immediate indication of an issue until it occurred.

My 2021 Kia Seltos EX is eating oil.......... 1/2 quart a week at least and I have read online that it can lead to the engine overheating, stalling, etc. So far my car is not listed on the piston recall or any other recall, but how can Kia state it can go 7,000 miles between oil changes when it only holds 4 1/2 quarts of oil and goes through it so fast? I change my oil every 3,500 miles because of it but am still afraid of something bad happening to my car.

I've owned this car since it was new. I've been disappointed with the transmission. At low speeds, it will hesitate and shudder. This is especially true if I'm making a turn. This has been a consistent problem. Secondly, twice my transmission has overheated. The first time we were in a Halloween event during the Pandemic 2020. It was a drive-through event that was stop-and-go. The warning light came on with the gauge showing one bar over the limit. As luck would have it, the traffic started to move towards the end and it lowered the bar to just under the overheating bar. The second time this happened it was much more serious. I had four people in the car. We had just left a restaurant and were heading towards the freeway. Unfortunately, we got stuck on a hill in Hollywood Bowl traffic. We were stuck there long enough that my car shut down on the hill. We were blocking traffic and my wife got out to direct traffic around us. I tried to put the car in neutral and coast towards an open curbside parking space. It wouldn't budge. We spent what felt like an eternity blocking traffic. It was probably 4-5 minutes where we were unable to start or roll backward.

Motor stalled while driving down the road almost causing an accident with my son and wouldn’t run again on my brand new Kia Seltos right under 37,000 miles. Towed the car to the dealership & they said the motor was blown they insist it’s my fault because I can’t provide a receipt for an oil change in a 10month period. I purchased brand new with and extended premium KIA warranty and they won’t do anything, sorry we can’t help you. They say all they can do is replace the motor while charging me $7,600. The motor never had lights flashing with oil pressure, overheating or any alerts it just died while driving down the road.
