I’ve been told by multiple Kia dealerships that my Kia needs a new engine however I am barely outside of their class action lawsuit so they are not willing to settle with me. They recently within the last two months came out with two recalls that did not fix the issue.
I took my vehicle to the dealership in Chantilly, VA on May 17, 2025. On July 24, 2025, I discovered that my vehicle had no oil, despite being approximately 4,000 miles away from my next scheduled oil change. I have video documentation confirming that there was no oil in the vehicle. The car was towed back to the dealership; however, no corrective action was taken. The dealership offered to perfo...
Engine has been burning oil for at least a year now. Cause ignition coil/spark plug failure and have replaced all 4 coils and plugs 3 times now within a year. Engine will randomly start to sputter after about 3-5 months of replacement. Adding a quart of oil every 1-2 weeks. No leaks and no smoke, just money down the drain.
While driving, the vehicle experienced a sudden loss of engine power and entered limp mode. The check engine light began flashing and the vehicle had very limited acceleration, creating a safety concern when driving in traffic. The vehicle was towed to a Kia dealership for diagnosis.

Immediately after getting Kia's latest recall "Voluntary Emissions Service Campaign" software update, my transmission began to Hard-Shift between neutral and 1st gear, and when slowing down, from a gear to a neutral position with the transmission. The car has lunged a few times when going from neutral to 1st gear position--concerning. This is most noticeable when car is cold, but is still always ...
Took to Kia for engine burning excessive oil. They determined the cylinder wall was scorched due to piston ring. The warranty people say it’s normal wear and tear and won’t honor the warranty. It’s still sitting in their engine bay because they want me to pay for the diagnostic which I don’t have. $4000 roughly for that but it needs a new engine. The warranty should be covering this! NEVER P...
