FUEL/PROPULSION SYSTEM
My vehicle is currently under a recall (recall SC356), but I'm currently very far from a Kia dealership. The nearest one is about 175 miles away. I contacted Kia and they informed me that they can't reimburse me for having my car towed to the dealership. So now I am stuck with a car that could possibly catch fire at anytime, according to the recall notice. And they refuse to help me.

UNKNOWN OR OTHER
The vehicle experienced a failure directly related to a manufacturer recall involving fuel tank expansion. The incident occurred while the vehicle was in use during normal operation on a work trip approximately three hours away from home. This failure presents a serious safety concern due to the involvement of the fuel system, including the risk of fuel leakage, system failure, or potential fire hazard. The condition made the vehicle unsafe to operate and required immediate attention. The vehicle was taken to a dealership, where it was inspected and the issue was confirmed to be related to the recall. The dealership determined that the vehicle is a total loss and cannot be repaired. The failure has not been reproduced as the vehicle is no longer operable. The vehicle remains at the dealership and should be available for inspection upon request. UNKNOWN if warning lights or messages appeared prior to the failure. The issue occurred during normal driving conditions. The manufacturer has been notified and a case was opened; however, no resolution or response has been provided to date despite multiple attempts to follow up.

UNKNOWN OR OTHER
The infotainment system in my 2022 Kia K5 began failing on or around early December, 2025, at approximately 44,000 miles and has continued to worsen. The vehicle is currently at approximately 47,000 miles. The screen displays the Kia startup screen repeatedly and does not fully load, flashing, becoming unresponsive, and ultimately causing distraction while driving. Audio may still function, but key features such as Bluetooth, Apple CarPlay, and auxiliary input do not work. The backup camera will either not function at all or will flash intermittently while reversing. This failure affects safe operation of the vehicle because it limits access to vehicle controls and creates distraction while driving due to the malfunctioning display. It also impacts visibility and usability of integrated systems that are expected to function reliably. The problem has been reproduced consistently and was evaluated by a Kia dealership. The dealership was unable to determine a clear cause for the failure but recommended full replacement of the infotainment system at a cost of approximately $6,700. There were no clear warning messages prior to failure. The issue has persisted despite attempts to reset the system and power cycle the vehicle. This appears to be a premature failure of a critical electronic system that should not occur at this mileage.

TIRES
I brought my car into Dyer Kia on March 16, 2025 to replace my rear passenger side tire that had a bubble in it.They finally agreed to replace the tire and after being there for 4 1/2 hours they sent me on my way and I was within 5 miles of home and I did hit a small hole in the road and the tire immediately went flat. This tire was the one that they had just replaced in January on the passenger side front I contacted them again and told them that I was going to go to a tire dealer and put on new tires and send them the bill because now I am afraid to even drive my car. Sending them the bill is probably a moot point but it’s worth a shot. My car is brand new has approximately 1450 miles on it and I’ve already had three flats. I had actually told my sales rep while I was waiting for my tire to be put on that Dyer Kia should actually replace all four of my tires with new tires and not Pirelli’s. And he said that’s never gonna happen.I don’t understand why they would put as they call it a racing performance tire on a street car. I had four new Goodyear tires put on the car and the minute I drove away with a new tires, You could feel a total difference in the ride. I hope nobody dies because of all these defective Pirelli tires 235/45/18

TIRES
On March 14, 2026 I discovered that my rear passenger tire had a large bubble. Pirelli P Zero All season 235/45/18. I contacted Dyer Kia about replacement and they told me that they could not get me in until Monday, this was Saturday. I was due to be somewhere on Sunday and told them I didn’t want to drive on the doughnut or on the tire with the bubble. They said there’s nothing we can do about it till Monday unless you want to go and purchase a tire and have it put on and we will see if we can reimburse you. That was not an option. Especially they after said we’ll see if we can reimburse. I went to there service department on Monday, March 16, 2026 at 8 AM. I told the service tech that the tire was in the trunk and it had a large bubble in it and it needed to be replaced. This tire had approximately 1400 miles on it. This is the second tire in two months that I have had to have replaced. They told me that I must’ve hit a pothole because that’s what causes sidewall bubbles. I disagree. They finally agreed to replace the tire and after being there for 4 1/2 hours they sent me on my way and I was within 5 miles of home and I did hit a small hole in the road and the tire immediately went flat.

TIRES
On 1/12/26 I brought my 2025 Kia K5 to Dyer Kia in Lake Wales, Florida, for a blow out on my right front tire. The tire had 700 miles on it. I have only had the car since October 2025. Car was new. Tire is a Perelli and tire size is 235/45/18. When I got there the service technician told me that I ran over something. I did not. I was on a smooth road, no debris on the road. I had two other people in the car with me and they can verify that there was nothing on the road because we walked the road to see if there was any debris. They replaced it under their pro Care policy, because I had not purchased road hazard. I didn’t purchase that because it came in a package that I couldn’t afford. They did replace the tire and then I had to pay for the tire sensor because they said it was faulty. I don’t think I should’ve had to pay for that but that’s another story.

FUEL/PROPULSION SYSTEM, SEATS
On March 9, 2026, I brought my vehicle to a Kia dealership in Alexandria, Virginia after experiencing a loud thump noise from the rear of the vehicle while stopped at a red light. (3/08/2026) Immediately following the incident, I smelled gasoline, noticed a significant drop in fuel economy, and heard persistent road noise as if a window were open. I explained these concerns in detail to the service advisor and specifically stated my belief that the fuel tank may have expanded. I was informed that this was not related to any recall. After approximately two hours, my vehicle was returned to me without resolution. The symptoms persisted, including the smell of gasoline, which poses a clear safety risk. A few days later, I took my vehicle to a second Kia dealership for further inspection related to Recall SC356. At that time, I was informed that my initial concern was correct—the fuel tank had in fact expanded. I was initially told the repair would take 3–4 days due to parts ordering. However, I was subsequently contacted and instructed not to retrieve my vehicle, as Kia is now pursuing a buyback. While I understand the seriousness of the issue, I am currently without a vehicle, and I have not been provided with a rental or loaner. Given that this issue is tied to a safety-related recall and that my vehicle is unsafe to operate due to the presence of fuel odor, this situation is both unreasonable and unacceptable. They have yet to send me any reports from the second Kia dealership in which I had taken it on 3/14/2026 I was only told over the phone via a service advisor named India that I was correct in suspecting the fuel tank had expanded causing the gasoline fumes and road noise

ELECTRICAL SYSTEM, ENGINE
Shortly after a routine oil change performed at a Kia dealership, I discovered a significant oil leak underneath the vehicle the following day. Within a short period of time, the vehicle began experiencing engine-related issues including a cylinder misfire, noticeable shaking while driving, and loss of power, particularly when accelerating or driving on inclines. The vehicle also displayed a check engine light and a warning related to 12-volt battery drain. In addition, I noticed a strong burning odor coming from the engine area, which raised concerns about a possible fluid leak or internal engine issue. These conditions created a safety concern because the vehicle would hesitate and lose power during normal driving, which could increase the risk of an accident, especially in traffic or when merging or climbing inclines. The vehicle was returned to a Kia dealership for inspection. I was informed that a cylinder issue was suspected; however, only a temporary repair involving a coil swap was performed. No comprehensive diagnostic testing was completed to confirm the root cause of the problem. After the repair, the vehicle continued to exhibit abnormal behavior, including shaking and lack of power. Due to ongoing safety concerns and lack of confidence in the vehicle’s reliability, I stopped driving the vehicle. This issue occurred at relatively low mileage, raising concerns about a potential engine defect or unresolved mechanical failure.

ELECTRICAL SYSTEM
Kia has a known wiring‑harness defect that causes the low engine oil sensor to trigger incorrectly. Despite this, there has been no recall, and new vehicles are still being sold with the issue. The wiring harness is now on back order, leaving me without a car for weeks or longer. The vehicle has plenty of oil, and the dealership confirmed there are no engine problems, yet the warning light keeps coming back because of the faulty harness. This happened 1 day after buying this car new from the dealership lot.

STRUCTURE:BODY, FUEL/PROPULSION SYSTEM
My 2023 Kia K5 experienced a fuel system issue related to Recall SC288 (Fuel Tank Inspection & ECM Update). The vehicle displayed a check engine light and could not accept fuel while refueling. The vehicle was taken to a Kia dealership on May 21, 2025 where the recall inspection failed. The repair order states the fuel tank swelled and damaged the body of the vehicle. Kia opened a Techline case and retained possession of the vehicle. Kia has now acknowledged the vehicle is not repairable. The vehicle has been in Kia’s possession since May 2025. This situation resulted in extended loss of use and financial hardship.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
While driving, the entire control panel shuts down including all interior and exterior lights. It completely resets everything including Bluetooth. It has happened 5 or 6 times since I got the car in October 2024. I’ve reported this to Stones Kia in Idaho Falls, and they were unable to duplicate the issue so they couldn’t do anything. It tends to only happen when I’m driving at night.
