When Kia problems show up
| Measure | Value | What it means |
|---|---|---|
| Average age at failure | 5.28 years | How old the car was when the problem happened |
| Reported inside 3 years | 33.3% | Share of complaints filed while the factory warranty was likely still running |
| Complaints describing a crash | 2,035 | Of 38,959 total |
| Complaints describing a fire | 1,755 | Of 38,959 total |
A low average age does not automatically mean a fragile car: a brand with a young fleet on the road will always skew early. Read it next to the share reported inside three years.

Kia complaints by model year
A bad generation shows up here as a block of years, not as a single spike. Recent years look quiet simply because those cars are young and still under warranty.

My [XXX] daughter was a passenger in a vehicle involved in a crash in which the vehicle struck a tree and a fire was present. She was unable to exit the vehicle and did not receive medical attention in time. Public records indicate the vehicle had an open federal safety recall at the time, listed as incomplete. I am submitting this information for awareness and review. I am not making any conclusions regarding causation. However, I believe it is important that incidents involving vehicle fires and open recalls are documented and evaluated to help protect other families. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
A recall was issued to me by kia in 2017 when we had the vehicle's engine totally replaced. On may 16, 2019 my son was driving when passerby's were honking and flashing their lights at him. He noticed that the engine was on fire, when he lost steering, and breaks. He jumped out of the car while moving and then the car exploded, a total of 3 separate times before fire and emergency personnel arrived on scene. Fire report and investigation underway
As soon as I pulled it off the lot within a few months I had some stalling where it would only go 30 mph I was pushing down on the gas full blown and then all of a sudden it would jerk and then it would go again I took it to the dealership the first time in 2016 and I told him that and they said they couldn't help me there was nothing wrong with it so I said okay second time and did it I took it back there and said there's something wrong do some testing they did some testing nothing.

I was driving down the highway at approximately 70 mph, and a deer ran into the front driver's side corner of the car. The airbag fortunately didn’t deploy, but the hood flew up and covered the windshield, blocking my ability to see. I was somehow able to pull the vehicle over without being able to see. Within 30 seconds of pulling over—and while I was still in the driver's seat—I noticed flames coming out of the engine compartment. I screamed to my son to get out of the car, and within minutes the car was completely engulfed in flames. The car burned to the ground and is a total loss. I have no idea how this could have possibly happened. This shouldn't have happened from a deer. The vehicle was only 7 months old, was up to date on all required maintenance and recalls, and had approximately 11,000 miles on it. It was in perfect condition. We were able to escape, but for a moment I thought we might not be able to. We're lucky to be alive. I reported the issue to my insurance company and the manufacturer and have received no information on causation. A link to the video of the car burning is below: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Electrical System 1,747 Read
I was driving this car and received a check engine light and lulled over to find an electrical fire had occurred under the hood. I was able to use a fire extinguisher to put out this fire. The car was towed to a Kia dealership near my home for confirmation and an estimate of the damages. It apparently was caused by a problem that Kia has had with the ABS/hydraulic electronic control units that can trigger electrical shorts
I was driving my car on the highway, then I got the message çheck your electrical system'for around a minute. Then there was a rumble or bang as if I hit something with the back, but the road was clean. Then the car started slowing down and I drove to the side. I got out of the car and saw white smoke coming from under the car in the back. I started opening the hood and trunk in the back to find out, where the smoke came from. It was nothing to see. Because it was an electrical car I assumed, that it could start burning, when it smells like smoke and looks like smoke. So I called 911 and told them, that I think my electric car is starting to burn, where I am and that nobody was injured. I took everything out of the car, closed the hood, the trunk and the doors and moved in a safe distance at the side. Around 10 minutes later firefighters arrived and started to put out the fire with a water hose. They opened the trunk, removed the covers there and put water an top of the burned part. The fire wasn't that big. I think, I acted fast enough, to stop it early. I think the battery started to burn. Nothing else was affected. The police called a towing truck and the car is now at the towing yard. It happend 3 hours ago. Police came, I have a filenumber and the insurance has also been informed. I took some pictures of the small fire, the smoke and the melted parts in the trunk after the fire was stopped

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

How we count
Every figure here comes from complaints owners filed with NHTSA — 1,116,631 of them, covering 2,022 models built between 1981 and 2026.
A complaint is an unverified report: someone wrote down what happened to their car. It is not a confirmed defect and not a recall. What makes the volume useful is the pattern — when thousands of owners of the same build describe the same failure, that is a signal no marketing brochure will give you.
Two things we do that the source does not. First, we compute the age of the car at the moment of failure from the incident date and the model year. Second, we group complaints by the first 11 characters of the VIN — the production series — so a bad plant run does not disappear into a model-wide average.
