2021 Kia K5

On [XXX] I took my automobile, a 2021 Kia K5 to Planet KIA of Charlotte NC located at 4700 E independence Blvd. I took it there to check what caused my engine light to activate. The initial diagnosis was a bad Sensor-Differential Pressure. Planet KIA repaired the Sensor-Differential Pressure at the cost of $501.17. My extended warranty company Route 66 covered $350.28 while I covered the remaining balance of $150.89. The engine light came on again the next day and while driving back to the dealership, I experienced the car slowing down and difficult to gain speed in highway traffic. I returned the automobile to Planet Kia of Charlotte and on [XXX}, I was informed that I had a valve failure which in turn caused my gas tank to swell. On [XXX] the warranty company denied request to pay for repairs due to their policy of not covering emissions which pertained to the valve. Kia refused to fix this problem due to a service campaign recall had been performed on the vehicle before I bought it. They found no issues with the vehicle pertaining to the valve or gas tank swelling. This is clearly a manufacturer’s defect, and it should have been repaired by the manufacturer. If you can, please help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The Electric seats do not adjust due to failed motors. Electric mirrors do not adjust due to failed motors. Gas refuel door does not open due to faulty actuator. All things that make the care dangerous to drive. Online search reveals that all three issues are very common in the 2021-2023 KIA K5 cars. We believe they pose a danger. Also, they seem to break at about 40-60K miles. Often out of warranty and dealer will not fix even though they acknowledge that the items in question are an issue.

For breaks: at 20k miles the steering wheel shakes like crazy when braking, and also the pedals: the rotors are very cheap for being a 0-mile purchase vehicle and Kia does not replace this under warranty. I saw a forum that this is an issue for all owners of this Kia K5 and Kia doesn't care and does not replace them. For Electrical issue: the fuse box melted a couple fuse because I used my rear defrost system. Kia extended the warranty for the HVAC motor fan only because was burning the fuses, but they did not wanted to replace my issue with the rear defrost because I was above 60k for only 1000 miles. This is a poor-quality system, Kia does not recognize it. This is a safety issue because 1. There is an electrical issue with a melted fuse box. Im driving around a car like this with 2 kids. 2. I don't have rear defrost working and I live in Chicago (wild winter). They want to charge +$6000 to repair the fuse box.

On Mon, Nov 18, 2025, I was driving at 60 mph with cruise on. Suddenly cruise was cancelled and check engine and low oil pressure lights came on. I pulled off road at earliest point possible. Seemed to be running ok. Drove slowly to a convenience store and turned off engine. I checked oil and it was low. When I was walking out to car after buying some oil, I saw oil under car. I called tow service and had it delivered to dealership. Upon inspection, the dealership determined the oil drain plug had fallen out and the engine needs to be replaced. The oil had been changed by an independent shop at 75085 miles. This incident happened at 78,887 miles. I feel the drain plug would have fallen out before 3002 miles if it was put in loose. This issue needs to be made into a recall with reimbursements for engine replacements and towing. If this had happened on a busy road and engine seized, there could have been a wreck trying to get off road.
