FUEL/PROPULSION SYSTEM, STRUCTURE:BODY, SEATS
While accelerating in response to a green light I made a right hand turn and as I accelerated up to the speed limit of 55 mph I heard and felt a very loud “bang or pop”. I proceeded to pull the car over anticipating a tire blow out or something damaging the rear end of my car and upon a full visual inspection of all tires, undercarriage, under the hood and in the truck and main cabin of the car I was unable to locate and issues and there were zero codes or lights. After careful assessment I proceeded to get myself and child home but on the way the car started stumbling and there was a strong Oder of gas. A check engine Illuminated giving us an error code referencing our solenoid that works in pair with our fuel system. After checking the car and going inside for about two hours, my husband came to me and asked what happened to the backseat as the entire thing had been pulled up and underneath it was a very pressurized and round fuel system. I proceeded to call the car dealership service department and told them the codes and everything I was showing and what was happening and asked when I could get the car to them, and if it was safe to ride, they said if it’s still ran to go smoothly to the dealership which was a 10 minute drive. As directed by the dealership I brought the car for service and I also located a voluntary emissions report that Kia issued in April of 2024 along with a copy of letters said to be sent to each owner of my make and model. I never received these letters and update not completed. Kia failed to effectively notify all owners of this potential issue with an over pressurized fuel system, putting myself and my children in great risk. Kia America stated they needed to study my car. A recall still has not been issued, although there are several complaints of the same thing in their cars and now I’m forced into a very unfair buyback and I am being penalized due to Kia failing to alert All parties. There is still no recall.

POWER TRAIN, ENGINE, FUEL/PROPULSION SYSTEM
The vehicle has experienced repeated transmission-related issues, including erratic shifting, delayed response, slippage, and sudden loss of power while driving. These symptoms significantly impact drivability and pose a safety risk, especially when accelerating or merging in traffic. The issue was previously addressed by the dealership under a recall repair. However, the same transmission behavior has returned approximately 3–4 months after the repair. The dealership performed repairs multiple times before, and the symptoms have now recurred. The problem has been confirmed by the authorized dealership and is scheduled for another inspection. There have been warning symptoms such as hesitation during gear shifts and intermittent power dips while in motion, which began reappearing recently. The component remains available for inspection. Given the repeat nature of the issue following an official recall, I believe this may be part of a broader unresolved defect in the vehicle’s transmission system. The issue initially reappeared briefly after the recall repair, then subsided. However, it returned more consistently and noticeably after a couple of months, and is now ongoing.

I was driving with no other cars around, and i heard what sounded to be an explosion, come to find out my sunroof had exploded. I had glass fly all over the back windshield, and onto the road behind me. This could have caused an accident or damage to other vehicles if someone was around me.

I was driving on [XXX] and I heard a really loud sound like a Gun Shot in my Car I couldn't just pull over I had to get off at the next exit when I did I checked myself and then I checked my Windows then I opened my back door on the passenger side and saw that behind the seat had swollen up. I drove to work and call KIA where I purchased the car and told them what happened my husband carried the car to them and to make a long story short. After Months of back & forth it was determined that the GAS TANK had EXPANDED!!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
While driving, thankfully not with my [XXX] son, the vehicle made a real big bang noise and lost power. Looked back and the whole back seat was lifted. Towed to dealer and tech found that fuel tank had expanded and exploded seat back. Incident happened in November 2024, and to this day, Kia has been the most difficult to deal with. They offered to buy vehicle back, but we have been waiting for a long time for answers and resolution of this issue. Its impossible to get someone on the phone and we keep getting the run around with a loaner/rental while trying to continue to live normal life going to work and dropping kid at school INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
2023 Kia K5 GT1, once at 16k miles and now again at 26k miles, while driving, the dashboard console flickered on me and the car lost complete acceleration and power, fortunately on urban roads or else would have been extremely unsafe and dangerous if high speed, especially since I have a child. Pulled over and turned off vehicle, and turned back on acceleration regained but check engine light remains solid. Took it to dealer at 16k miles and they checked it out and just reset the codes, advised if it happened again to bring it back right away. I am aware of the open recall on this Kia model, but my specific vehicle VIN is not impacted. However, I suspect the sudden power loss issue is the exact same issue. This is an extremely dangerous and unsafe issue with this vehicle, particularly if you have kids or are driving high-speeds on the highway!!!!

STRUCTURE:BODY
The back chrome cover around the rear windshield all 3 pieces are coming loose and I had the one on my passenger side fly off while I was going down the highway and the piece almost hit the truck behind me thankfully traffic wasn’t to bad on the highway so he was able to hit his breaks and maneuver out of the way before. I currently have 2 more pieces trying to come off. After doing further research I have seen hundreds of other post from k5 owners years 23&24 all having the exact same issue of the chrome pieces coming off and or flying off while driving. In the pictures you can see the one missing piece and the other 2 you can see where the other 2 pieces are starting to loosen up. If you physically touch it they both will move and feel loose. I believe this should be a recall before one of the pieces fly off and cause a accident by hitting another car like what almost happened in my case or just flying off and hitting a person. I bought my car used but it was a single owner my car was a little over a year old I’ve personally had it for I believe 10-11 months and I keep it in the carport daily so I shouldn’t be having these issues already.

TIRES:SIDEWALL
tire size 235/45 R18. Both front tires at 7,300 miles suddenly have bulging out of the side wall. One tire bulge the size of a golf ball, the other tire slightly larger in size. No warnings or inflation issues prior to failure. Severe safety risk. Risk of blowout is high. Car not drivable due to risk of blowout. Contacted Pirelli the manufacturer, was told both tires are to be sent to them for inspection by the dealership. Pirelli customer service indicated the issue will likely not be covered under warranty.

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
My current 2021 Kia K5 FUEL TANK EXPLODED while driving. I’ve had this car for about 5 years and since driving it off the lot have experience issues with the vehicle and just a few hours ago, the fuel gas tank explode raising the back seat with passengers in the vehicle. It was extremely scary and something out of the blew. My friends and I were driving and I noticed the car engine light turn on (which was so odd to me as I keep a close eye to the car maintenance) and within 20 minutes we heard two EXTREMELY loud explosions sounds come from the car with the feeling of the car shake and rise a bit and felt as a tire exploded. I did not find this usual and we pulled over and the the seat my friend was sitting on was rose and unlatched. We then did some google searches and when looking into it, it appears there have been previous issues with this situation for other K5 Kia owners but KIA has done nothing regarding the matter. A few months ago I also went due to an internal thermostat exploding and causing the engine to overheat and smoke on the freeway and because they deemed it was not under the warranty, I left car-less for a week and a high bill. I don’t understand why I have to pay and endure these service costs when this is BASIC CAR FUNCTIONS. I do not appreciate the lack of empathy from dealer and service staff and feel unsafe and concerned for my safety for driving this vehicle. And now II have to endure the costs of being car less for 14 days per the dealer. Absurd.

AIR BAGS
I was involved in a head on collision, all of my safety warning notified me but my airbags NEVER deployed. This is a serious safety hazard especially with many problems being reported with airbag deployment. The adjuster and collision center both stated at the rate of speed from the accident, the airbags should have definitely deployed. My car was deemed a total loss from the damage even without the deployment.

ELECTRICAL SYSTEM
This has happened on 2 occasions, 1 while starting the car 1 while driving. Both times the cars volume went to max with either radio or Bluetooth on and produced a static noise with it. The volume knob did not adjust the piercing noise unless set to 0 or mute. This was remedied by pulling the amp fuze and reseting the radio. I had no lights or warnings pop up, and have yet to have this inspected by a dealership. This instant volume switch to max output with static while driving almost caused an accident as I was distracted trying to turn down my radio as quickly as possible with pain in my ears on the interstate. While stationary even after turning down the radio I still have lingering pain from how loud it was. From what I can tell this is something with the radio unit or amp within the car.

SERVICE BRAKES
Brake Rotors from factory warp very early, noticable in under 30k miles. Warped rotors makes braking harsh, makes the brakes not work as well ans steering wheel jolt when braking making it dangerous. Was diagnosed by myself and other K5 drivers who took their cars to dealerships and mechanics. No warning lamps or anything, just very rough braking. Happened to me around 24,000 miles

POWER TRAIN
I had plenty of time to pull onto a perpendicular street. While accelerating the car would not shift to next gear. It hit about 4.2 rpm and still did not shift. I was almost hit!!!! After pulIing over to safety, I ensured it was not in manual mode. Started driving again and It wouldn’t go more than like 20 mph. I pulled over a second time and shut it off. Started it up again and it worked fine. 603 miles on this car. Kia is not interested in quality it seems.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, LANE DEPARTURE: BLIND SPOT DETECTION, FORWARD COLLISION AVOIDANCE: WARNINGS
These warnings light up at the same time the dash for Electronic stability system, electronic parking brake, forward collision system, Auto hold and engine light, saying "check forward collision system, check blind spot detection, check smart cruise control system", and the vehicle goes into a sort of limp mode, not allowing it to accelerate past about 40 mph easily. In my research, I've have found approximately 50 other Kia k5 owners who have had this exact same issue. Half of the time, once taken to the dealership for diagnosis, it is weeks without anyone figuring out what the issue might be. Several instances where a part has been replaced which did not fix the issue at all, like an airbag module, or steering column. Several instances of the ecu and hecu being replaced, and several more of the entire engine/chassis wire harness being replaced. As for my case, now at the dealership for 2nd time because they could not reproduce warning lights while test driving vehicle. They have determined mine requires a full chassis wire harness replacement, with an estimated cost of $5k-$7k, which includes the $2800 harness. I initially thought mine was an isolated incident, and was shocked to find as many owners as I have that have experienced the same issue, some with mileage as low 25 miles, and causing sudden braking or issue with steering the vehicle. Being that it involves all the major safety systems of the vehicle, I am also surprised there has not been any sort of recall, considering these issues span all the way back to 2021. Just my two cents. Currently waiting on a tech to come out and determine if this is covered under extended warranty bought at dealership at time of purchase, as I am over the 60k mile factory warranty period. Have had this vehicle for 3+ years, and this just now started happening about a month and a half ago. Some have had this issue just weeks after leaving the lot with their brand new car, and a few of those returned the vehicle for a refund.
