FUEL/PROPULSION SYSTEM, STRUCTURE:BODY
While driving, the check engine light came on. Soon after, the rear floor of my 2021 Kia K5 lifted upward, and I noticed the fuel tank underneath had swollen. When I opened the gas cap, it blew off with force and gasoline sprayed on me, soaking my clothes. This could have caused a fire or explosion. The car is now unsafe to drive, and the rear seat cannot be used because the floor is deformed. I discovered that Kia has a Voluntary Emissions Service Campaign SC288 addressing this exact issue (fuel tank swelling and excessive pressure due to a faulty PCSV valve and EVAP system), but this is clearly a safety hazard, not just an emissions problem. Many other owners have reported the same issue online. I believe this defect should be escalated to a safety recall before someone gets seriously injured or worse.

The K5 - as soon as I began driving it at 0 miles, I noticed it shifted at lower speeds extremely hard. Head-jerking hard during the first drive of each day at speeds below 25mph. Once the vehicle warmed up, the problem would go away and wouldn't appear until the next day - after the vehicle cooled down completely. I thought, maybe there was a break-in period. So I drove it for about 250 total miles. At that point, I made a service call and brought it into the dealership. I left it overnight. Explained all of the symptoms. The next day, one of your service advisors test drove the vehicle. I was called and told they were unable to reproduce the problem and that I could come pick up the car. I was told by your service advisor that the problem "could be rats or rodents in my garage". I was greatly taken back by that suggestion because I live in an upscale neighborhood, with a highly secured finished garage and have never had any rodent problems. I mentioned that to the service advisor, and she said "You'd be surprised how many people tell us they don't and we find out they had a rodent in their garage". I couldn't believe I was having a conversation of such sorts. I laughed it off and took the vehicle home, quite disgusted that it was suggested that this hard shifting might be "My problem because of rodents". I explained this to [XXX] that evening and couldn't believe that was even brought up given the situation. The very next day, the vehicle did the same thing at about 20 to 25 mph, and extremely hard, head-jerking shift on the first drive of the day. I have now driven the vehicle 3000 miles since new. I have tried driving in several different driving "modes". I've tried, Sport, My Drive, and others, but it doesn't seem to help. Every time I get in my car at O'hare after flying a trip, I look forward to driving a brand new car home, but left extremely disappointed when I drive away from the employee lot only to have an extremely hard, head-jerking shift for the first INFORMATION REDACTED PURSUANT TO THE FREEDOM O

ELECTRICAL SYSTEM
Kia has a known issue with the HVAC blower motor circuit on this vehicle model. They have issued a warranty extension related to relocating the blower motor fuse to another circuit in the fuse box, due to potential burning of fuse(s). After executing this extended warranty fuse-relocation-procedure, our blower motor relay burned and was replaced twice by separate Kia dealers. Kia is now claiming that our entire wire harness needs to be replaced at our own cost. It is quite obvious that any wire harness issue is now very dangerous (electrical arcing and melting) and was caused by the original motor circuit issue. (The two Kia dealers agree with our assessment but are saying that Kia will not repair because original warranty extension was limited to rewiring.) Safety issues: Electrical fire hazard (already demonstrated with burning/melting fuse-box before and after extended warranty procedure was executed). No A/C in 95 degree F conditions.

I was driving my car and heard a loud pop, I was on the interstate and thought maybe my tire was going flat but nothing alerted me on my dash. I heard loud wind noises but everything seemed fine until my car started basically hopping forward and it became hard to accelerate. I had to push the gas harder than normal to maintain average highway speeds. I was also feeling super lightheaded while driving and kept rolling my window down as if I couldn’t get a full breath of air. I would roll it back up after 5 minutes or so and would have to roll it right back down. I was driving a long distance and wasn’t able to immediately stop but I was informed of the gasoline fumes when I family member helped get my bags out of my car. It was the scariest thing

Driving down the highway and heard a pop and my seats were rising slowly and while trying to make it to the nearest exit only two minutes later my rpm’s started jumping and my engine just shut off and multiple dash lights came on. Had it towed to Kia and after they did an inspection they said that my fuel tank had expanded and was pushing on my fuel lines and pushing my back seats up.

The contact owns a 2022 Kia K5. While the contact's son was driving at an undisclosed speed, the rear seat started to rise independently. There were no warning lights illuminated. The contact's husband was sitting on the rear seat. In addition, the contact stated that the failure had occurred after the vehicle was refueled. The vehicle was taken to the dealer where it was diagnosed with an expanded fuel tank. The contact was informed that the fuel tank needed to be replaced. The vehicle was repaired. The contact stated that the repair had taken three weeks. The vehicle was returned to the contact. The contact stated that two weeks later, the manufacturer began sending emails to the contact, which stated that the vehicle was under recall. The contact was advised to park and not drive the vehicle. The vehicle was towed to the dealer. The vehicle remained at the dealer for two additional months. The manufacturer informed the contact that the vehicle was non-repairable. The contact had not received an offer for a replacement vehicle and the contact was still required to continue monthly payments. In addition, the contact was concerned because her husband had been driving an unsafe vehicle for two weeks after the repair was performed by the dealer. The failure mileage was approximately 79,000.

FUEL/PROPULSION SYSTEM
I am submitting an update regarding my 2023 Kia K5 (VIN: [XXX] ). •On July 25, 2025, I delivered the vehicle to my dealership for recall-related fuel tank issues. •As of today (61 days later), the vehicle remains out of service and undrivable. •The dealership opened a Kia Techline case, confirming they are unable to repair the fuel tank issue and that it is a safety hazard. •Kia North America has not provided any resolution, despite repeated contacts and escalation of my case (Kia Claim #25408405). •I have incurred significant financial hardship, including paying the monthly car loan, maintaining minimum insurance, and paying for out-of-pocket rental expenses while Kia holds my vehicle. •I also contacted Kia Finance, and they confirmed my hardship notes are documented in their system. This situation is ongoing, with no repair performed, no reimbursement, and no safe solution provided. The recall remains unresolved, and the vehicle is unavailable for use. I request that NHTSA take immediate action to ensure Kia complies with its recall obligations and consumer safety requirements.

While driving at about 70 MPH the right rear tire locked up temporarily causing loss of control of the vehicle. Luckily there were not other cars around as the car was in 3 lanes prior to coming to a complete stop. If this happened in traffic it could have caused a significant accident. There were no warning lamps on dash before or after the incident. After inspecting vehicle on side of road I could not see any issues. Drove about 15 yards and heard a grinding noise. Vehicle was towed to dealership. Dealership has inspected vehicle and advised it was caused by a failed awd coupler. The repair will be covered by warranty.

The car has a sudden loss of power but doesn't shut off. The drivers eat doesn't move towards or back and the back seat popped up for no reason whatsoever. We have taken it to the dealership and they say its not a recall but its doing the same things that others in the same year and model are doing. Why isn't this one on the list . Its paid off and haven't been able to drive it for a year now . Wasted money getting it towed to dealership and back . Ridiculous!!!!

FUEL/PROPULSION SYSTEM
I took my car because of fuel recall, due to multiple vehicles having their gas tank expanding or exploding. Even after they completed the recall on my vehicle I still had my gas tank expand. I took my vehicle to the Kia Frisco dealership and they took my vehicle advising they had to buy it back from me. Once they had the vehicle after close to a month they stated that my vehicle was repairable even after stating that several of these models had gas tanks expanding and exploding. I do not feel safe getting into this vehicle after the repair and I want to report it.

VISIBILITY/WIPER
My 2025 Kia K5 with less than 10k miles on it is experiencing intermittent windshield wiper failure. Starting over two months ago, my windshield wipers would fail in the sense they would not turn on while it is raining and/or would not activate when I use the sprayer function leaving residue and obstructing my view in both scenarios. This is a critical safety issue that has been documented on video, however the dealership/Kia are not being forthcoming in fixing the issue. My car has been in the shop over a week at Mark Kia and there is still not a remedy for the issue. They claim to not being able to reproduce the issue and will not do further diagnostics until it happens. The car is leased and I do not feel safe driving it knowing there is a chance my wipers can fail intermittently (as they have while it has been raining) so I'm filing this complaint.

TIRES
Tire size: P 235/45 R 18 While I was driving home from work my steering started feeling a little shaky. My commute is 6.5 miles. I thought it felt a little weird about 2-3 miles in and I called my boyfriend to meet me when I got home because I could tell something was off, but my tire pressure was fine. When I was about .5 miles from our home, the shaking became audible and violent so I got scared and pulled off. I called again for help while I was parked and walked around to see if there was anything weird and I could not see anything. About 3-4 minutes later while I was sitting in my car waiting, my tire exploded. It shook my car and was so loud that people ran out of the building I was in front of to see what happened. At this point, I had a tire indicator come up saying something was wrong. When I walked around my car again, I saw in one of my tires the cords came out and split in middle of the tread causing separation, and the tire still had air in it. It also scratched my paint around the tire. When I had help come, we put my spare on and got it home, and we took it to a tire dealer the following morning. They all were shocked at how new the tire was and what happened. Everyone is so glad I was parked when it happened and upon research, this is a common occurrence with this brand and type of tire anywhere with 1000-10000 miles on it. My vehicle is less than 6800 mi and the specialists even said the tire had basically no wear and was faulty. On top of that, Pirelli warranty essentially refused to process anything and the dealer that THEY told us they would work with, Pirelli kept hanging up on them. They would not give me a name, let me speak to a supervisor, or give me a call back number should the call “disconnect” again. The dealer was able to comp the tire through their management, but even then, the issue of the faulty tire remains, and based on what I felt, I don’t want someone to get hurt having this happen to them while their car is in motion.

The contact owns a 2025 Kia K5. The contact stated that while her daughter was driving at an undisclosed speed, the Tire Pressure Monitoring System (TPMS) warning light illuminated. The contact's daughter took the vehicle to a specialty tire shop, and it was determined that the front driver’s side tire had two bubbles. One bubble was located on the top, and one bubble was on the front side. The tire was replaced. The tire manufacturer was made aware of the failure and referred the contact to the vehicle manufacturer for assistance. The failure mileage was approximately 2,500.

I was driving down the highway and my car made a loud bang noise. It would not accelerate over 50 mph no matter how hard I pressed the accelerator. Took to dealership and they told me I needed a new battery and charged me $365. Drove it and still won’t go over 50 mph. They kept it for a week and said it had a faulty valve that caused pressure to make the gas tank expand, pushing up back seat. Said it wasn’t a recall and would cost me $3600 to fix. Told me it was too dangerous to drive. Did research and saw that this was discovered over 2 years ago but I was never told. Now they say I have too many miles on my car to fix it. The gas fumes inside the car are intolerable and it still won’t go over 50.

Transmission has extremely hard shifting if vehicle sits for more than 24 hours. After the vehicle is parked, inside garage, or outside, the first drive of the day has an extremely hard shift of the transmission on the first shifting of the day. The shift it so hard, it jerks the entire car and jolts me in my seat. The remainder of the drive and day, the hard shifting does not occur. Took the vehicle into dealership where purchased at 1000 miles and left it with them for 2 full days. Unsurprisingly, they said they were, "Unable to reproduce". The next day, the vehicle had the exact same problem. I have close to 3000 miles on the vehicle and the transmission continues to do the exact same thing every time I drive it. It is terrible for a brand new car. It doesn't matter which "Drive mode" the vehicle is in. The dealership also tried to reset the ECM. But no luck. My neck and back have been sore from the hard shift events too.
