   For starters, my lights go out every six months on queue. Cannot find a reason why. My car sputters or shutters when accelerating. I heard other Kia models have recalls due to the same thing. I have had my car in the shop multiple times and no one can figure out why it is doing it. It feels like the belts are slipping or the transmission is slipping or something, but no one can find a legit reason as to why. This has been happening since I bought the car and it has never stopped with anything I have tried to do or I’ve had inspected.

   The engine started knocking while I was on [XXX] between mile marker [XXX] and [XXX]. This area is under construction with no shoulders to access and pull over. A shutdown in this situation would surely cause a multi-car accident. There were no warning lamps. Car was towed to Ancira Kia in San Antonio. Here is the RO# [XXX] for reference. Also case number from Kia [XXX]. As there is no current Recall Kia refused to take responsibility. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

   We purchased a brand-new 2021 Kia Sedona in 2021. Since January, we’ve been experiencing an intermittent but serious issue where the vehicle refuses to accelerate or shift beyond a certain point. This issue has put us in dangerous situations multiple times. One incident occurred while crossing a fast-moving, single-lane road—our vehicle would not accelerate to the appropriate speed, placing us at serious risk. On another occasion, while merging onto a highway, the car failed to accelerate, and we feared being rear-ended due to our inability to keep up with traffic. There are no warning lights or error messages to indicate a problem when this occurs. The only temporary solution has been to pull over, turn the car off, and restart it. After doing this, the vehicle functions normally for a few days, weeks, or even months before the issue reoccurs. We have taken the vehicle to our local Kia dealership, but they were unable to replicate the problem or identify any issues. We also brought it to a second Kia dealership with the same result—no diagnosis and no resolution. We are extremely concerned for our safety and would appreciate guidance on how to escalate this issue or pursue a resolution. I also have a video of an incident.

   I was in a car wreck and my air bags did not deploy and my seat belt did not lock. The other vehicle involved in the car accident immediately deployed its airbags. I did not ask for an ambulance because I do not know if my insurance covers it so I went personally to the emergency room after the accident.

6. Filed Jun 1, 2024Failure Jan 23, 2024Sandwich, ILTread/belt

   The first of four tire failures (all the same DOT Number) of the OEM tires that were on the 2021 Kia Sedona when purchased in April, 2021. The first tire belt broke when on an approximate 1000 mile drive and was replaced on an emergency basis on January 24, 2024 with 16,760 miles on the vehicle. The second tire belt broke on the trip home and was replaced on an emergency basis on March 8, 2024 with 18,927. After arriving home, the tires were inspected, found to have defective belts and were replaced with a warranty adjustment by Discount Tire in Oswego with 19,191 miles. Kumho has still not honored the warranty by sending checks for the first two defective tires. (Can't find receipt from warranty replacement by Discount Tires but will continue looking. Have many photos of defective tire if desired.)

8. Filed Jun 26, 2021Failure Jun 26, 2021Milwaukee, WIUnknown or otherCrash

   Vehicle is easily stolen, and is a safety risk for others. Kia's are getting stolen at an alarming rate and should be recalled! Not only are they getting stolen but they pose a major safety risk because the people stealing them are crashing them, running from police, etc. Damage to my own property as well as others (mine had mysterious damage but I have no idea who or what they hit). Something must be done!

   DATE OF INCIDENT: 22 APR 2021, THURSDAY DESCRIPTION OF INCIDENT: WHILE DRIVING ON CRUISE CONTROL AT 45 MPH ON A WELL-PAVED TWO-LANE ROAD WITH NO OTHER VEHICLES OR OBSTACLES PRESENT IN EITHER LANE, THE VEHICLE SUDDENLY AUTOMATICALLY DECELERATED SHARPLY, CAUSING THE FRONT END TO PLUNGE. SIMULTANEOUSLY, SEVERAL ALERTS, BOTH IN WORDS AND SYMBOLS FLASHED ON THE DASH. THESE INCLUDED 'CHECK COLLISION ALERT' AND LIGHTS SHOWING A SKIDDING VEHICLE AND A SECOND SHOWING THE FRONT OF A VEHICLE IN A CRASH. ALTERNATING MY ATTENTION BETWEEN THE ALERTS/MESSAGES ON THE DASH AND DRIVING THE VEHICLE, I STEERED TO THE SIDE OF THE ROAD AND STOPPED. THE ENGINE WAS TURNED OFF AND THEN RESTARTED. ALL ALERTS AND SYMBOLS WERE EXTINGUISHED. AN INSPECTION OF THE FRONT OF THE VEHICLE SHOWED NOTHING COVERING OR OBSTRUCTING ANY PORTION OF THE VEHICLE. I ACCELERATED BACK ONTO THE ROAD AND RETURNED TO A SPEED OF 45 MPH WITHOUT USING CRUISE CONTROL. THE VEHICLE RETURNED TO NORMAL DRIVING WITH NO ALERTS OR WARNING SYMBOLS. AFTER DRIVING APPROXIMATELY ANOTHER 20 MILES, WITH TWO PERIODS OF PARKING THE VEHICLE, THE CRUISE CONTROL WAS AGAIN ENGAGED AT 45 MPH ON AN OTHERWISE EMPTY ROAD. WHILE I ATTEMPTED TO EXIT THE FOLLOWING-DISTANCE CONTROL FEATURE, THE VEHICLE AGAIN BRAKED SUDDENLY WITH THE SAME SET OF ALERTS AND SYMBOLS AS DURING THE FIRST INCIDENT. AGAIN STEERING TO THE ROAD SHOULDER, THE ENGINE WAS STOPPED AND RESTARTED WITH ALL ALERTS/SYMBOLS EXTINGUISHED EXCEPT THE CHECK ENGINE LIGHT.
