While driving down the road the car said it had a major voltage failure and was shutting down. I was in the middle of the street and thankfully was able to coast to the turn lane before the car came to a total stop. since the gas pedal didn't do anything. the car then said there was multiple failures and the hybrid system needed to be immediately shut down. The car then wouldn't start or move after that. about 20 mins later the car like dashboard and screen would turn on but the engine would not. when it turned back on there were even more warnings along with other failures like emergency braking and transmission and the hybrid communication. when the tow truck came and took it it would go into neutral to get on the truck but wouldn't even do that when we got it to the dealership it had to be manually taken out of park to get it off the truck. there were lots of warning lights but the oil, engine, and another light I not sure what it meant were always on even when the others would go away after a while.

UNKNOWN When slowing to a stop, the vehicle spontaneously makes a sudden jolt, throwing passengers forward. It-€™s as if the the transmission malfunctions when down shifting and results in engine braking.

Engine overhead and stopped working in addition to it consuming massive amounts of oil without physically putting oil in. I've went to 2 dealerships who refuse to provide me with a new engine even though I'm covered under the engine extension warranty due to me having the knock sensor update done. I am now involving my attorney and will go to the news channels to inform how kia manufacturer has become a disgrace with not providing quality engines in their vehicles and don't want to be responsible for it. there's already a settlement going on for kia optimas and other cars they've made because of faulty engines. They can better believe I'm coming for them next with a lawsuit.

I purchased my Kia optima brand new I believe it had 7 miles on it when I purchased it, shortly after it was purchased it started having a problem with the transmission, I would go to takeoff and it was lunch and jerk pretty hard to where it was very noticeable. I took it into the shop they thought that it was something a computer program could reset they performed that I did not fix it, I don-€™t drive my Kia very much I barely have 25,000 miles on it right now I am a real live in care provider so I don-€™t drive very much my job is at home. I have taken the car into several dealerships repeatedly to have it fixed, IA really was at a loss and did not know what to do because I had taken it to two different dealerships and the problem was never resolved. I contacted an attorney they got nowhere because apparently I needed to take my car in one more time within a timeframe for them to be able to do anything about it? And any right, still to this day the car does the same thing it-€™s been in the shop four or five times for this problem. One time I took it to Kia and Elk Grove they kept it looked at it said they couldn-€™t find the problem. Every time I-€™m renting a car paying for the insurance going through the inconvenience of renting a car paying extra insurance etc. just to have nothing done with my car. When I went to pick up my car from the Elk Grove dealership I threw a fit because I was tired of it and I said look somethings wrong with the car I-€™m not a mechanic I can-€™t tell you what it is but I need this car fixed, the service manager came out and said I-€™ll take a a ride with you and we-€™ll see if maybe I can see what the problem is we didn-€™t even get out of the parking lot and it jerked so hard at the service manager noted it in the file had me drop it back off and leave it it-€™s still wasn-€™t fixed. I took it in again after that the new service manager took it on an hour drive on the freeway hooked up to a computer with Kia and of course it didn-€™t do anything while h

When driving this vehicle rattles and shakes it has a burning smell/gas smell. It cuts off while driving. Looses oil.oil at low level before due. This make and model is no longer being manufactured. It has a known history of engine problems. Why were consumers allowed to buy this car. Problems are active and ongoing. Started about a year or close to a year after purchase. It is a lemon. The dealer wants to diagnose the engine, but they already know the engine is no good.

I was told by the dealership that my 2018 Kia Optima phev was repaired but after I drove it off the lot and got on the freeway the warning light came on again and lost all power. I almost got into another accident because of this. The dealership said they worked with Kia technical support to fix my car but apparently Kia doesn't know what's wrong with their own car. The vehicle has only 19K miles. I'm afraid for my safety and my families that this will continue to happen.

This issue has happened multiple times to not only myself. It my wife as well. As we're driving anywhere above 45mph. A warning display comes on telling us to check the hev, to pull over, and turn off our vehicle. We comply to the warning and when restarting the vehicle, check engine light comes on and then same issue happens again a few minutes after driving. One out of the four times that this issue has occured to us, the vehicle completely died on my wife due to the battery not charging. So when she pulled over and tried to turn the vehicle back on, it wouldn't restart. Code on car is P2600 generic coolant pump circuit a open. Everywhere says recall isn't available for our car but am seeing that same issue with our year, make, and model is occurring. Which is the hybrid propulsion system is being affected. The voltage protection device (vpd), designed to protect the high voltage battery module is being activated inadvertently.
