One day I was driving and my car began to shake really bad. It doesn-??t transition smoothly when switching gears in transmission. Sometimes it doesn-??t accelerate and I-??d have to floor the gas to get it going. Rough acceleration. Car would even shake in idle sometimes. It has been doing this ever since. One day it-??ll shake, the next day it might not. It doesn-??t matter if I drive slower or faster, the car still shakes, has rough to no acceleration, and shifts gears roughly. Engine light is on and is reading misfire of cylinder 3.

Transmission is itself in neutral while driving. Resulting in irratic RPMs, hesitating acceleration and rough transition to gears. Took care into dealership service department. They seemed that I would need a transmission replacement. Kia approved the request. Still waiting on transmission to be put in.

The contact owns a 2023 Kia K5. The contact stated that while driving on several occasions at various speeds, while the transmission was changing gear, the vehicle hesitated and jerked abnormally. The vehicle was taken to a dealer however, the failure could not be replicated. The manufacturer was notified of the failure. The failure mileage was approximately 34,000.

When driving my car will send off all dashboard lights, sounds. Lose acceleration. Pull over, rmps fly up and won. Turn car off and turn back on to regain acceleration. Engine light remains on. I know there is a recall for this for my exact car type, but the recall does not show up under my VIN. After a phone call with NHTSA, I was told to report my vehicle to the website. My safety and others is at risk for obvious reasons. This can easily cause a crash. This happened once at 5K miles, dealership supposedly fixed it. But it happened again the other day at 19K miles. There are no warnings prior to my vehicle going into safe mode.

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".

My wife was driving down the highway with her cruise control set to 75. She noticed she was only doing 71 and pushed the gas pedal manually. The rpm's increased to between 4000-5000 but there was no acceleration with the car. The car then dropped to 68 mph and would not accelerate at all. After pulling over and turning the car off and then restarting it started working ok. This seems to match the transmission recall of the 2023 Kia K5 GT-Line but this car is not currently included in that recall. This recall should be investigated and possibly expanded.
