I was driving the car at about 45 mph, and suddenly the check engine light, battery, and the oil light all came on at once and my car stopped moving. Thought it was the battery or the starter at first but now I'm pretty sure its either the engine got locked up or the wires in the car just burnt up.

I was on the interstate traveling at approx 70 mph changed lanes and when I went to accelerate the vehicle stalled lost power I coasted to the breakdown lane and attempted to start the vehicle. It would not start. I had aaa tow it to a hardings garage in fairfield. The technician said this morning the vehicle started but stalled as soon as he tried to move it. He told me that there was a Kia recall 17V224000 that applied to the engine so I got aaa to tow the vehicle to charlies Kia in augusta, me. They tell me that there is no recall on my VIN. Why would I have the same stalling as indicated in the recall if my VIN does not apply"?"

On 9/3/2019 I took my 2012 Kia Optima to gossett Kia South to get it repaired. It didnt get fixed before I left the lot my car was smoking and leaking antifreeze. I was stranded for 4 days after that day. I went to the nearest part store and purchased a bottom radiator hose and antifreeze. I had a mobile mechanic to put the hose on. There after I was stranded again the car wouldn't start. I had it towed to Firestone 10/4/2019. My car stayed the lot for a month and it was then towed to gossett Kia North from there it has been repossessed. I made payment arrangements to get the car back I am determined to get my car repaired. I use the car to make it to appointments. I am disabled and this doesnt seem fair at all im paying notes on a nonworking car. I hope to hear from you soon with further advice

Kia has now settled their class action suit for all the other vehicles, yet the hybrids are still being left out of any recalls. There is plenty of evidence in the complaints here that something is wrong. I sunk $7000 that I didn't have to spare into getting a new engine put in this car. Only to have the transmission blow right after I got the car back from Kia after waiting 6 months for an engine. The transmission cost another $5000, and it took them three transmissions to install a non-faulty transmission. I almost lost my job because I couldn't reliably get to work on time, if at all. Kia themselves have said that the engines weren't manufactured correctly and that labor being done in Kia dealerships wasn't being done correctly. Hybrid engines should absolutely not be blowing rods at 60000 miles, or 80000 miles, and not even 100000 miles. Kia is knowingly delaying any sort of recall and forcing people to go into further debt or lose jobs.

During my last visit to the Kia dealer for an oil change and tire rotation, they informed my that I had no oil indicating on the dip stick. No leaks detected so must be burning oil. Every time I drive, I can smell burning oil and tail pipe are completely black.
