Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Was driving down a busy local road when out of no where, I heard a lound explosion. I looked at the rear view mirror thinking something had crashed into the back windshield, but there was nothing. I got out to check the car and noticed a huge hole in my sunroof. The glass had shattered and pieces were everywhere. I called Kia to see if it would be covered under warranty, but they told me that they've never come across something like this. I even showed them many sources online of people complaining about the same exact issue and they still failed to acknowledge the defect. …”

NHTSA complaint #11114680, filed 2018-07, 40,118 miles

“While driving down a straight path on an interstate at roughly 70 MPH, the sunroof of the vehicle exploded with a sound like a bomb going off. The dealer is claiming the explosion was caused by a dimple in the roof of the car caused by a rock or an object that hit the car at some point. However, the dealership - and online research - shows that there have been multiple instances of sunroofs exploding in this make/model/year of kias but no recall has been registered as yet.”

“2015 Kia Cadenza panoramic sunroof spontaneously exploded while driving on the highway. Sounded like a bomb exploded in the car and there was no external object involved.”

NHTSA complaint #11279519, filed 2019-11, 36,200 miles

“We noticed that when we would close our car doors it would make a large popping sound and we realized that it was the windshield. I touched it and when I did it lifted from the car. The windshield is not secured to the car! I haven't had the car a year yet and it is still under warranty. I have scheduled an appointment with Kia to have this repaired.”

NHTSA complaint #11153441, filed 2018-11

“The windshield on my car is loose and leaky - water leaks in during rain and wind noise at moderate speeds. I can push from the inside and separate the windshield from the vehicle with minimal effort. There is NHTSA Recall 22V158 for Kia windshield separation on 2014-2016 Cadenzas. I took the vehicle to 2 different Kia service centers and called Kia Consumer Assistance Center, and I still cannot get them to fix this issue. This is a family car and my young children travel in it and it is not safe. please help.”
