I was driving down I25 around 530pm after work when all of a sudden my sliding sunroof glass exploded. There was no one around me at all thank god because the glass went everywhere and I didn't have my 10yr old son in the car as I usually do. Kia in motor city Colorado springs is where we bought it. This was our first low milage expensive car we have ever bought. Kia told us its not there problem and we must have hit a rock or something but this was false. As I hit nothing.

The antenna fin on my vehicle flew off at freeway speeds. Kia states it is not covered by the extended warranty. I have done research and have found 2014, some of 2015, and 2016 Kia Optima have been recalled for this reason. I have contacted Kia and they told me my vehicle was not part of the recall. The antenna fin on my vehicle has come off in the same manor as my of the vehicles reported and are a part of the recalls. I have attached a picture that shows the screws had been sheared off which you can see in the photo. This could have and may still cause a serious safety hazard to other drivers on the road.

I have a 2015 Kia Optima purchased in October 2017 with 34K miles approx. I am constantly putting oil in my car and it seems to evaporate in 2-3 days. There is no leak and we have no idea why the car is consuming so much oil. Lately the car has been knocking and when accelerating to merge onto highway, the vehicle starts to sputter and begins to stall. I do not feel safe in this vehicle with my children and no longer use this vehicle on a daily basis. After doing some research, I find that this year vehicle has the most overall consumer complaints and there still has yet to be a recall on the engine" I do not understand why Kia skipped this year?? let alone blame consumers that it's their fault for not following the maintenance schedule, yet when told the schedule has been followed, will find some other lame excuse so the manufacturer is not at fault. What is it going to take to have this engine recalled" we as consumers, myself, a single hard working parent, do not have the means to buy another vehicle just because Kia says it's not their fault. This problem started beginning of April 2019, my vehicle has 52K.

Was driving on the freeway at about 55 mph, got in lane 4 to exit the highway when my engine just turned off. I drifted to the side of the highway and tried to restart the engine. When I tried to restart the engine smoke started to come from the engine. Towed the vehicle to the dealership where they stated that they would call me with any updates (this was after telling me that it would cost $165 to diagnose). Just got the ECU updated approx. 6 months ago. No check engine light or anything popped up on the dash, just got the oil changed 06/15/2019. There are approx. 118K miles.

I own a 2015 Kia Optima. I have a panoramic sunroof that stretches he entire length of the car. I was driving down the highway during a very brutal winter where we had temperatures in the minus category a few times. While driving on the beltway doing approx. 55mph, there was a loud sound that sounded like a gun sh*t. When I was able to safely get somewhere so I could see what happened, I noticed that my sunroof had exploded and shattered. The cover was not open because it was winter, so luckily the shattered glass collected into on top of the cover, otherwise it would have blown throughout my car and whoever was in it at the time causing physical harm. I was told by the dealership that they had heard it happened before, and because of the temperature something made the glass expand.

On October 15, 2018, I purchased from pep boys four Goodyear all season 205/65R16 tires. On two separate occasions since then I have had a tire puncture and flatten immediately as a result of very little measurable side impact with a curb. After researching this matter online I have determined that others are having the same issue with this Goodyear style tire. I have written to Goodyear CEO richard kramer three times (see attached documents) and Goodyear's response to date has been lacking.

This complaint has nothing to do with my vehicle. It is about other people's vehicles that have the super-bright headlights. I get temporarily blinded by these late model vehicles with new technology headlights (hid or led) when they are coming toward me. I have long respected the oversight provided for vehicle safety in this country and have always trusted that proper considerations are made to ensure vehicles are safe. But I can't for the life of me understand how the super-bright headlights have made it past safety considerations, and that they have not been regulated out of existence. It shouldn't be that hard to define maximum limits for headlight intensity and effective lighting distance that would prevent the blinding of oncoming drivers. This is a major issue on american roads, and I'd be shocked if it hasn't already caused accidents, injuries, and death. Please rectify this oversight immediately to ensure that the reputation of american car/road safety is restored and to prevent needless injuries and death.

At approximately 4:30 a.M. on November 12, 2018, the engine became fully engulfed in flames while the car was parked on the street in front of our house and turned off. No one had driven the car for several hours. The fire destroyed the entire front end of the car, melted the tires and filled the interior of the car with smoke. Fortunately, the fire department arrived and put out the fire before it spread to the gas tank.
