Loss of power even hitting the gas. Sputters and does not accelerate. Had spark plugs changed thinking it will resolve the problem and it didn't. Severe safety hazard even needed to get up speed

Received an oil change as part of normal service schedule on a 2023 Kia K5 vehicle purchased August of 2022 (from different dealership). 4 days after this service was conducted, the drain plug in the oil system of the vehicle fell out of my car, therefore draining my vehicle of the oil it needs to operate normally, causing the car to completely stall near my home. I had to pay out of pocket at a nearby Express Oil Change facility to have a new drain plug and oil put into car, after which I immediately brought my vehicle back to this dealership to ascertain what happened. This is the SECOND time this same exact issue has occurred with my vehicle (the first time occurring after an oil change at a different Kia dealership in Charlotte, NC), which I brought to my service advisor's attention prior to them beginning the oil change service. I expressed to this service department that I am extremely concerned there is something malfunctioning or defective within the vehicle that has caused this issue TWICE in an almost-new vehicle, and that I was now concerned there could be possible damage to my engine from this reoccurring issue. The service department at Kia Wesley Chapel did absolutely nothing to address my concerns or the issue other than replacing the drain plug (yet again). This Kia service department, and KIA overall, refuses to recognize or admit to any issue within the vehicle, and I was told to "wait and see if it happens again".

The car was 4 months old when I was trying to get home when all of a sudden I noticed all the engine lights started to go out. With a few minutes on the road, the car automatically shut down in the middle of the road. My head almost hit the steering wheel and I was so close to hitting another car. I tried to start the car but it wouldn't start, the engine was making a strange noise and it smelled like burning. I waited 45 minutes on the side of the road and started the car. I drove the car to Kia and the fastest the car will go was 25 miles. When I got to Kia I explained everything that had happened to the car. They did not assure me that the Kia warranty was going to pay for everything and that they were going to investigate what was wrong with the car. It was a wiring issue and was covered under warranty. I brought the car home around 6:300 p.m. m. From the Kia body shop and before I pulled out of the parking lot, I had the same problem again! The check engine light came on and the car came to a screeching halt again. I drove the car back to the body shop. I didn't tell him anything about what was wrong with the car. The car was serviced, however you should have no problem with a new 2023 car.
