TIRES
235/46 r 18 tires currently have 28,000 miles and I’ve already replaced one tire due to lump on side wall that started developing at 12,000 miles and on other three tires. The tread is chipping and separating from the tire on the same pattern all three tires.

TIRES
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.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS
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.

WHEELS
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.

SUSPENSION, 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.

POWER TRAIN
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.

POWER TRAIN
There is a hard shift after the car has been parked. Bought the car with 6 miles on it, now has 35,000. This issue is not new, we have had it into 2 different dealerships, and neither "were able to duplicate the issue". It is increasingly getting worse so it will be going back to the shop yet again.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, VISIBILITY/WIPER
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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
While driving on the interstate at 70 miles an hour on cruise, I turned off cruise control in order to take control of my vehicle in order to change lanes and my car immediately took back the control and accelerated and then abruptly hit brakes at 70 miles an hour throwing me forward hitting my head which caused unconsciousness and when I came to, My air bags had deployed and my car was total lossed. Due to the state of shock and a concussion, I thought the car had hit an eighteen wheeler which was the last thing I remembered seeing in front of me due to the damages to my car. However, the truck was not there and my car was against the wall where it had stopped. I don’t know if something like debris came from under the truck that was in front of me causing the sensors to engage due to the abrupt stop causing me to hit my head and knocking me on conscious. No other vehicle was at the scene and my car had significant damage causing it to be a total loss.

TIRES
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. I had actually told my sales rep while I was waiting for my tire to be put on that Dyer Kia should actually replace all four of my tires with new tires and not Pirelli’s. And he said that’s never gonna happen.I don’t understand why they would put as they call it a racing performance tire on a street car. I had four new Goodyear tires put on the car and the minute I drove away with a new tires, You could feel a total difference in the ride. I hope nobody dies because of all these defective Pirelli tires 235/45/18

TIRES
On March 14, 2026 I discovered that my rear passenger tire had a large bubble. Pirelli P Zero All season 235/45/18. I contacted Dyer Kia about replacement and they told me that they could not get me in until Monday, this was Saturday. I was due to be somewhere on Sunday and told them I didn’t want to drive on the doughnut or on the tire with the bubble. They said there’s nothing we can do about it till Monday unless you want to go and purchase a tire and have it put on and we will see if we can reimburse you. That was not an option. Especially they after said we’ll see if we can reimburse. I went to there service department on Monday, March 16, 2026 at 8 AM. I told the service tech that the tire was in the trunk and it had a large bubble in it and it needed to be replaced. This tire had approximately 1400 miles on it. This is the second tire in two months that I have had to have replaced. They told me that I must’ve hit a pothole because that’s what causes sidewall bubbles. I disagree. 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.

TIRES
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.

ELECTRICAL SYSTEM, ENGINE
Shortly after a routine oil change performed at a Kia dealership, I discovered a significant oil leak underneath the vehicle the following day. Within a short period of time, the vehicle began experiencing engine-related issues including a cylinder misfire, noticeable shaking while driving, and loss of power, particularly when accelerating or driving on inclines. The vehicle also displayed a check engine light and a warning related to 12-volt battery drain. In addition, I noticed a strong burning odor coming from the engine area, which raised concerns about a possible fluid leak or internal engine issue. These conditions created a safety concern because the vehicle would hesitate and lose power during normal driving, which could increase the risk of an accident, especially in traffic or when merging or climbing inclines. The vehicle was returned to a Kia dealership for inspection. I was informed that a cylinder issue was suspected; however, only a temporary repair involving a coil swap was performed. No comprehensive diagnostic testing was completed to confirm the root cause of the problem. After the repair, the vehicle continued to exhibit abnormal behavior, including shaking and lack of power. Due to ongoing safety concerns and lack of confidence in the vehicle’s reliability, I stopped driving the vehicle. This issue occurred at relatively low mileage, raising concerns about a potential engine defect or unresolved mechanical failure.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
While driving, the entire control panel shuts down including all interior and exterior lights. It completely resets everything including Bluetooth. It has happened 5 or 6 times since I got the car in October 2024. I’ve reported this to Stones Kia in Idaho Falls, and they were unable to duplicate the issue so they couldn’t do anything. It tends to only happen when I’m driving at night.

STRUCTURE:BODY
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.

TIRES
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

The contact owns a 2025 Kia K5. The contact stated that while driving at speeds over 55 MPH, the hood vibrated abnormally. The contact stated that while being overtaken by a box truck or semi-truck, the vibration of the hood was more pronounced. The driver's side of the hood had a quarter-inch to a half-inch gap. After arriving to the destination, the hood was closed; however, the hood failed to latch securely. The vehicle was taken to a local dealer and the dealer suggested that the two rubber stoppers needed to be tightened. The vehicle was not repaired. The manufacturer was not informed of the failure.
