Owner reports
Selected complaints filed with NHTSA by 2011 Kia Optima owners, lightly cleaned up (personal details are redacted by NHTSA).
While driving the Kia on the highway (in the passing lane on Route 93, Boston, MA), the hood of the car flew open and shattered the windshield. Prior to getting into the vehicle, there was no notification, warning light/display, that alerted to the hood or anything else not being 'closed', no rattling of the hood either. The hood blocked my entire vision with the exception of a small area below, where I miraculous got over to the breakdown lane without causing any accident. When I got out of the car, the hood was bent and the second latch was loose. It did not hold its shape. Called the police and the insurance company, the car was deemed a total loss. This incident occurred on January 31, 2026 at 10:05AM. The conditions were dry and sunny. …
The paint is delaminating and peeling in the section just above the windshield. This started in 2019 and has steadily getting worse. My car color is "Snow White Pearl". I have attached pictures. I had assumed that this was due to the age of the car until I started looking for solutions to fix it and keep it from getting worse. I have found that this is apparently an issue with the paint and is not due to age as there are hundreds of testimonials of other KIA owners with the exact same issue, especially owners with the "Snow White Pearl" paint color.
My Kia Optima is peeling paint around the top of the windshield. My car is beginning to rust. This is not normal. Reading online about this issue, and many people are seeing the exact same issue. My car is snow white in color.

I was sitting in a turn lane, to turn left. There were two lanes to my right for traffic. I was waiting for a car coming from the opposite direction. I happened to look in my rear view mirror and it was completely taken up by this red object, which happened to be a car. Immediately I felt a terrible shock and my car was lifted up in the rear and the front end pointed at the road. This car drove me approximately 40 yds. Up the road. The air bags did not deploy...none of them and there was $12,000 worth of damage done to my car. I still have lower back pain and severe cramps on the left side of neck and head. Of course the driver was dui, no license, no insurance and left the scene of the accident. On 10/22/12 my wife had driven home from florida to tn. She turned on a street heading up a hill toward our home. …
Vehicle was driven a mile to a commuter rail station for a drop off and back home. Nothing unusual was noted during the short trip nor had any problems been observed in the days leading up to the incident. Shortly after parking the vehicle on the 5th floor of the parking garage and entering the residence, the complex fire alarms actuated and all residents were advised to evacuate without entering the community parking garage. Shortly thereafter, I was notified by the complex manager via my cell phone that my car was on fire in the garage. The entire front of the vehicle was burned and was declared a total loss by the insurance company. (allstate). The entire car would have burned if it hadn't been parked directly under a sprinkler head in the garage plus a speedy response from the fire department. An independent fire origin investigator was hired by the insurance company. …
My passenger front door keeps going out of alignment. I have had it re-aligned many times. My body shop has informed me that the hinges need to be replaced. This is a safety issue , if the door is not aligned it May open at anytime. I have informed Kia , they have refused to assist me with this issue. Please assist me with this issue.
While driving to work early in the morning, traveling at about 55-60 MPH,without warning a startling sound like an explosion, once I realized it wasn't a tire blowout, I pulled over to find a hole in my roof. Thankfully I was alone and my children wasn't with me and no other vehicles were on the road at that time.
