Selected complaints filed with NHTSA by 2025 Kia K5 owners, lightly cleaned up (personal details are redacted by NHTSA).
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 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. …
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. …
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. …
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. …
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.
Within 1 month of purchasing this vehicle (new), the front passenger tire developed a bubble in the sidewall. We had to argue with the dealership to get it replaced. It had less than 200 miles on it. 7 months later there is a bubble in the sidewall of the front driver side tire. There is less than 9,000 miles on these tires. This is a safety issue and a defect that is not being addressed. We keep being told we must have hit a bump or something to cause this. I have owned many vehicles (more than I can count) and have never had this happen before. It should 100% be recalled or covered under warranty. Pirelli P Zero All Season 235/45R18 18-inch alloy
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.
At approximately 20,000 miles, an original-equipment Pirelli P Zero All Season 235/45R18 94V tire on my 2025 Kia K5 GT-Line suffered a sudden apparent tread/outer-shoulder separation while traveling at highway speed. The tire had been maintaining normal pressure and remained inflated, but a large portion separated and exposed the internal cords.
235/45 r18 at 12,000 miles miles. I've noticed that the front passenger side had a slight little lump on the side wall as it reached 28,000 that ball that bigger and bigger. Had to replace the tire due to the safety concerns. Noticed that the other three tires are showing other patterns of deformities.
