I am submitting this complaint regarding a leaking evaporator core in my 2021 Kia K5. The evaporator core failed at approximately 59,600 miles, causing the air conditioning system to stop cooling properly. The vehicle was diagnosed by a repair facility, which determined that the evaporator core was leaking refrigerant and required replacement. An evaporator core is a major HVAC component that should not fail at such low mileage under normal operating conditions. This failure affects the vehicle’s ability to properly dehumidify and defrost the windshield, which can reduce visibility and create a potential safety hazard during rain, high humidity, or cold weather conditions. I have maintained the vehicle as recommended and believe this component failed prematurely. Due to the extensive labor required to replace the evaporator core, the repair cost is significant. I am requesting that the federal safety agency review this issue to determine whether there is a pattern of premature evaporator core failures in 2021 Kia K5 vehicles and whether an investigation is warranted. Vehicle Information: * Year: 2021 * Make: Kia * Model: K5 * Mileage at Failure: 59,600 miles * Failure: Leaking evaporator core causing refrigerant loss and loss of air conditioning performance

I am writing to formally complain about the ongoing issues with my vehicle, specifically the repeated failure of the air conditioning system and the excessive number of recalls that have caused major inconvenience and lost work time. The air conditioning unit in my vehicle has failed three separate times. Each time, I was told the fan motor needed to be replaced, and the motor has now been replaced three times. After each repair, the system works temporarily before failing again. I have now been informed that the issue may actually be electrical in nature, which raises concerns that the original problem was never properly diagnosed or repaired. In addition to the air conditioning problems, my vehicle has been subject to multiple recalls requiring repeated trips for repairs. These ongoing issues have forced me to miss work several times, causing financial hardship, stress, and a loss of confidence in the reliability and safety of my vehicle. At this point, I am requesting the following: A full inspection and proper diagnosis of the electrical system related to the air conditioning failure. A permanent repair solution rather than temporary fixes. Reimbursement or compensation for repeated repair visits, missed work time, and inconvenience caused by these recurring issues. A review of my vehicle’s repair history to determine whether additional corrective action is appropriate. I have made every effort to address these issues through the proper service channels, but the recurring failures continue. I expect this matter to be taken seriously and resolved promptly. Please contact me as soon as possible regarding the next steps to resolve this issue. Sincerely,

I have experienced consistent electrical issues with my drivers side door panel on my 2021 Kia K5. The lights on the panel will flash off and on intermittently, the windows will not roll down, and doors will not lock/unlock, posing an entrapment risk. Additionally, when this panel malfunctions, my power seat will move and adjust (sometimes while I am driving and the vehicle is in motion) back to original settings instead of remaining in the settings I've saved for my vehicle; fully unintended motion of course. Additionally, my media screen/multimedia face also experiences issues where it will black out, cutting my navigation mid-drive, as well as any other sound including music and/or navigation guidance. I initially raised these issues early in the ownership process of my vehicle with a door panel replacement being offered as a fix. This did not fix the issue. I was told i needed to try to get video of the incident when it occurred which seemed impossible.to me because under GA law, how am I supposed to obtain video while operating a motor vehicle. However, I eventually obtained footage. I expressed concern about the issue persusting past my warranty date and was told my issue would will be able to be fixed if it persisted because I initially raised it during the warranty period. However, I have now proceeded to be dismissed and blown off by both of thr Kia dealerships in my area regarding this issue. Even being told by one that they no longer had previous service records of my vehicle because they've changed ownership. As an authorized Kia service center, my understanding is that the dealership is an agents of the manufacturer. If they failed to transfer records, they are essentially admitting to a lapse in their duty to maintain my vehicle's history—a history that involves a life-threatening safety defect. There were no warning lamps for this issue, I've not had this issue inspected by my insurance or other agents.

I purchased a 2021 car in April 2024, which was originally side-swiped in November 2024. I filed an insurance claim and had to wait for the other insurer’s statement. In January 2025, the insurance company sent the car to one of their approved shops for electrical repairs, but the shop refused to work on it after noticing a missing airbag and flagged the car as a liability. They also mentioned the car had multiple past accidents and should have been listed as salvage, not clean title. I informed the dealership, but they refused to service the car, claiming the 30-day window had passed, even though their website states a 6-month warranty. Over the past year, I’ve been repairing the car myself and taking it to Kia and Midas, where I was told the car is in terrible condition. The dealership found water damage from a slow leak and wiring issues that were present when I bought the car. Now I’ve been quoted over $5,000 for repairs including a new computer and electrical work. I’ve tried reaching out to the dealership with no success. This car is essential for commuting to work and for my kids. I’ve had to rent a car for the past month, costing me over $1,000. I’m seeking assistance with this situation as I believe I was sold a defective vehicle without proper disclosure. I put down $4,000 when I purchased the car and have continued making small payments because I need it to commute and can’t afford another vehicle right now. I have Personal Injury Protection (PIP) with Progressive and comprehensive and collision coverage through the dealership’s partnered company, Brio Management, as they operate from the same office. Given these circumstances, I’m asking for help with this situation because I was sold a car with undisclosed damage and defects, and I’ve been left with costly repairs and rental expenses while the dealership won’t assist me.

The steering wheel became stiff all the sudden and became hard to turn. As well as all the warning lights came on when that happened such as Adaptive Cruise Control Automatic Emergency Braking Blind Spot Warning Forward Collision Warning Lane Departure Warning Lane Keeping Assistance Parking Collision Warning Rear Cross Traffic Warning. I was driving in the middle of the road when this happened and this could’ve caused a huge accident due to the fact that I couldn’t steer my car properly. No, the problem has not been resolved yet. It is in the dealership at the moment to be inspected. There was no problem prior to the other signs coming on besides low tire pressure. The appeared as I was driving on the road.
