I was driving about 40 mph and the engine and electrical systems just shut off. This is after an oil change, and with no warning signs. Luckily I wasn't on the freeway and was able to safely pull over. Still have no luck getting it restarted after being towed to my residence

I bought a 2015 Kia Optima ex brand new off the lot in October 2014. Since then I have had to replace both drivers side and passenger side window regulator modules. The first one that broke (passenger) in March 2016 and was told because the window shattered its not covered under warranty. To replace the module and window it was $700. The drivers side window regulator went bad in July 2017. That was $250 to replace since the window stayed in tact. Here we are November 2018 and for the second time the passenger side regulator has gone bad. That's 3 times I have replaced the same part with Kia genuine parts (purchased from Kia) in 4 years. I have done extensive research and many other people have had issues with the same thing.

Engine ( and electrical systems ) shut down (3 times) completely and unexpectedly, while car was in motion at highway speeds( twice) and once while at tolls. Also noticed that when you turn key occasionally, its like battery is dead. I believe that first and second times I was flashing hi beams at highway speeds. After these events happen, the mileage guage resets, and clock is wrong. Also notice that the radio flickers, , and or turns off on its own. Also, not able to reset trip mileage, and noticed that shifter button intermittently will not depress.

Kia Optima 2015 with 20K miles caught fire. Engine stopped while at red light, in drive. Strong smell of burning plastic. Called 911. Vehicle behind me called reporting seeing flames coming from underneath vehicle. Kia replaced entire engine with no explanation as to why this happened.

Shark fin antenna cover fell off. This is reported to happen to many 2015 Kia Optimas. There is no replacement fin and to fix the issue a whole antenna kit has to be installed. Apparently the screws that hold the antenna fin down rust overtime and eventually cause the fin to pop off. This presents a problem that would allow water to enter the vehicle and cause damage.

Tire sensor keeps going off. No damages to tire or no loss of air. When I put air in it goes off. A few days later sensor goes on again. It's been about a month.

Keep hearing a loud rattling noise from the left side of the engine. He is more so when the car is in park and early morning. Has gone to the shop twice for this issues and each time have been told they can not find the problem even provided a recording of the sound. Also the radio complete shuts off by itself has done this 3 times now. Once again have taking it to the dealer and nothing was done about because the problem would not duplicate it's self. The passenger window gets stuck and have to play with the knobs in order to get it to come back up. I got this car July 21. 2017. The car has been in the show twice. First time for a week. Second time 6 days. Still no solution. Was told by lemon law to take it back and have them service it again. Has to be seen by dearer service department four times for the same problem before they will help.

Takata recall. As I was driving on the highway, my car stopped on me during traffic flow. This has happened more than five times and I was almost killed with my small children in the vehicle. We have been suffering with this issue for over a whole year. On July 3,2017 my mother and I was coming home on the fwy and once again, during traffic flow, my car shut off while driving on the road. Luckily, I was able to pull over to get a safe spot before I crashed because there were so many cars coming behind me so fast and the side ramps we're very narrow. I have taken it in for servicing but for some reason, they are not able to find out what the problem is. I have taking it in and even left with them for almost a whole month at one time and still no diagnosis. Rental car after rental car. They installed a data recorder in my car and the first time they found no data, then they installed it again for another week and they claim that it was the fuel pump relay. So they installed a new fuel pump relay in my car. A few weeks later my car shut down again on the way coming home and in the freeway with my mother and 2 year neice. We we're almost killed. The car just shuts off while driving and says "goodbye" with no warning while driving this is how I know that this has something to do with the engine. Please help if you can. I do not feel safe in this car and we are in danger. Sometimes the lights in the car cut on and off too.

Takata recall: Driving the car down a city street when it suddenly ceased to accelerate. The power steering stopped as it coasted into a side street to get off the busy road. I could smell wires burning as a electrical fire.I immediately got myself and family out of the car afraid it was on fire. The inside of the car filled with electrical smell and smoke. I called the 360 Kia to have the car towed to the dealership since I bought a "gold" warranty when I purchased the vehicle they literally lost my car for six days and then called me wanting my service records stating the car had no oil in the motor. This is a outlandish lie! my car had plenty of oil in it...I never saw a engine light come on indicating that I had motor problems nor did I smell oil. This was a "sudden " malfunction. My car never ran hot nor did my gauges ever indicate a problem. I had the car for right at 40K miles and had a oil change due again at the end of April.

The blue tooth for the phone if allowed to ring can cause one to loose control. The ring can go well past 100 db. If we forget to turn our blue tooth off it actually hurts.
