The first time the collision warning lights and sounds came on when I was parked but had my engine on in the morning of 7/21/2026. The second time was when I was merging on a busy highway with cars going 65+mph... There were no cars around me, but the collision warning said crash, the sounds came on, and my brakes went into effect. I pulled off the road, and now I am terrified to drive my car. I called KIA and told them this. They sent out a tow. They had my car and told me that the computer on my car did not register any issues for both times this happened. Someone is taking my car home tonight and going on the same highway to see if it happens again.

KIA K5 2025 FORWARD COLLISION AVOIDANCE: WARNINGS

The turning lights keep flickering and the back trim became lose.

KIA K5 2025 STRUCTURE:BODY

While my 2025 Kia K5 was parked in the driveway, the front driver-side original-equipment Pirelli P Zero All Season tire suddenly blew out. I had just parked and walked inside when we heard a loud pop. There was no impact, no curb strike, and no driving event - the vehicle was stationary when the tire failed. The vehicle had approximately 16,500 miles.  This is part of an apparent pattern: my son purchased an identical 2025 Kia K5 on the same day from the same dealer. At about 22,000 miles, his front driver-side tire developed a sidewall bulge, and all four of his original-equipment Pirelli tires show rapid, uneven wear. Two identical vehicles, bought together, both experienced failure of the same tire position (front driver-side) - his bulging, mine blowing out - which strongly suggests a defect in the original-equipment tires and/or a vehicle alignment/suspension condition causing abnormal wear and failure.  No crash, injury, or fire resulted because the vehicle was parked. However, a sudden tire failure of this kind at highway speed would create a serious risk of a blowout, loss of control, and crash. The failed tire is available for inspection upon request. I am filing this complaint to document the failure and the pattern across two identical vehicles.

KIA K5 2025 WHEELS

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 request. The tires have not yet been inspected by a dealer or independent shop. I am filing this complaint to document the safety concern and the apparent pattern across two identical vehicles.

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.
