2025 Kia K5 problems

“I own a 2025 Kia K5 GT-Line that was purchased new. I have experienced repeated loss of traction and vehicle stability while driving on wet roads. During normal low-speed turns on wet pavement, the rear of the vehicle can suddenly lose traction and slide sideways when I apply light acceleration. This has occurred multiple times. I am not accelerating aggressively or traveling at an excessive speed when it happens. The loss of rear traction can be sudden enough that I feel I am temporarily losing control of the vehicle. The ESC/traction control system is enabled and there are no warning lights displayed. Tire pressures have been checked and are approximately 33–34 PSI, and I have not observed abnormal tire wear or visible tire damage. The problem appears to occur primarily on wet pavement while turning and applying even light throttle. I am concerned that the vehicle could spin or cause a collision, particularly during normal rainy driving conditions. I am reporting this because the behavior has occurred repeatedly and I believe the unexpected loss of rear traction and stability may present a safety risk. I would like this complaint documented and evaluated for…”

“While driving my car down the road my car's exterior headlights as well as all of the interior instrument and infotainment panels will completely black out and then come back on. This issue started approximately 2 months after buying my car. This has happened approximately 10 times total while driving it now. I was told by the dealership that there was nothing they could do since it was not a reproduceable issue, therefore I continued to drive my car. To me that is a safety issue when you are told as a customer that there is nothing they can do for your car that has an issue such as this while driving. I continued to call and inform them of when this issue came up while driving. My car was brought in for a recall in July 2025 for parking lamp logic. The dealership never reproduced this issue while in for service. The dealership has inspected the car for this issue amongst several other issues that still persist to the current date. There are no warning lamps/messages or symptoms of the problem prior to failure. This problem came up again this week while driving in the dark with multiple other cars behind me, in front of me and to the left of me at an…”

“While driving the entire car goes black kind of like you just turned it off. It has only happened at night time. The dash screen completely turns off and the headlights will go off. When it comes back on the dash has several lights on it such as the seatbelt is unbuckled (when I’m buckled), and other warning lights. This has been happening since September 2025. I take it to the dealership and they can’t seem to find anything wrong with it, and told me they “can’t do anything until the part completely fails” it’s creates a severe safety hazard since it only happens at night and the headlights also go off.”

“On startup, the engine took about an extra second to fire. The starter cranked noticeably longer than normal before the car turned on. Shortly after, I pulled out and turned onto a street. When I pressed the accelerator, there was no response at all. No rev increase and no acceleration. The car would not pick up speed. I switched to manual shift mode to try to force a gear change. When I changed gears, it took a couple of seconds to respond each time, much slower than normal. I managed to coast/limp to a nearby gas station. I shut the car off and restarted it, and the problem cleared completely. The car has driven normally since.”

“The car material itself is very cheap meaning it poor quality, very flimsy, I hit a curb and the grill and cover just broke so easily even though it was now a serious hit but very small and slight to the point where you can’t feel it. Now it’s just hanging off and shaking badly because of the poor material, it isn’t stuff enough to keep in place.”

“At approximately 22,000 miles, all four original-equipment Pirelli P Zero All Season tires on my 2025 Kia K5 are showing rapid and uneven tread wear that is far beyond normal for the mileage. Last week I discovered that the front driver-side tire has also developed a visible bulge/bubble in the sidewall, which indicates internal structural failure and an imminent risk of sudden blowout. There were no warning lights, no impact event, and no inflation problem before the bulge appeared. This is especially concerning because my father purchased an identical 2025 Kia K5 on the same day from the same dealer. His vehicle has significantly fewer miles, yet his front driver-side tire suddenly blew out while parked in his driveway. The fact that two identical vehicles, purchased together, both experienced failure of the same tire position points to a possible defect in the original-equipment tires and/or a vehicle alignment/suspension condition causing abnormal wear. No crash or injury has occurred yet, but a sidewall bulge at highway speed creates a serious risk of a blowout, loss of control, and crash. The vehicle and the affected tire are available for inspection upon…”
