I experience a bms warning light on my hybrid vehicle indicating to stop the vehicle and do not drive. This happen on the fast lane of the 14 freeway in acton ca. I took the car to the local Kia I was told it was the hybrid coolant a computer program and a hybrid drive belt replaced the computer program. The update of the program I would of not know about the issue since only dealers are aware of it. I paid over $700 when I picked up my car for the repairs. Drove it the next day I experience loss of power again when I was trying to cross an intersection in the city of acton. My car almost stop and the hev warning light came on. Called the dealer again and was told to bring it right away. The service advisor called me after a week and half later and told me the problem was the power relay assembly and the hybrid battery that had to be replaced. Per repair adviser, this issue is a common but for him to do the repairs I would need to pay $5800. He did advise to call Kia corporation for possible assistance but they were no help. Since I can not afford the 5800. I picked up my car again from the dealership and paid an additional $318 for diagnose services. This is a known issue with Kia since the service adviser told me he only had a bulletin memo of possible issues with loss of power. I asked if this warrant a recall but the answer was no since it's only a memo and the batteries are built to last only 150,000 miles I was lucky it lasted and additional 18000. Miles. I just bought this vehicle 3 years ago and now I'm sitting on a giant paper weight since I can not drive my car to avoid further damage or possibly cause an accident.

After receiving an regular maintenance oil change on 8/25/20 @3:42pm my vehicle started to turn off and on and loud knocking coming from the engine so I immediately turned around and went back to jiffy lube where I received the oil change and they performed a second oil change baffled as to why my vehicle was making the noise after the oil change after the 2 consecutive oil change the knocking was worse and they instructed me to go to a dealership asap....as I was going to the closest dealership my vehicle stopped repeatedly on the highway my 5 year old grand daughter and I was terribly afraid people were honking their horns speeding past and my car stopped under a bridge turn about stopping traffic and it was very frightening and frustrating when I made it to the dealership the man told me that I would have to pay @ $140 to have the technician look at it and that they were closing at 5 so I called aaa to tow my vehicle home and I don't understand why this happened when I keep the maintenance on my car...please help, thank you that was a very frightening experience for me and my grand daughter

We were getting off the highway headed home the car made a loud noise as we were approaching the light one I've never heard before I didn't think anything of it so as we pulled off from the light got down the street the car just locked up and shut off like there was a flash of light or something coming from the hood and it didn't want to stop scared me and my kids so after I made sure everything was okay I waited til we stopped put it back in park and turned my key back over to pull over out the street fully so I can check it there it was my alternator bracket broke without a clue why no physical contact or anything whatsoever alternator is not damaged neither was the belt on it bad I know that when I took it to a mechanic and that's another thing no one nowhere could give me and answer for it so it's like it overheated it off and broke the engine piece my only theory nothing else is damaged around it or anything so that's weird for a piece to just break so I did research on the Kia Optima and stumbled across the overheation and the fueling problem.

I had taken the vehicle to the Kia dealer in orange county, and they charged me extra to resolve the recall, and the vehicle's air conditioning system is no longer working, the gas intake is ridiculous, and the car does not have the same power as it used to.

I was driving on the road on a nice sunny day, and while my vehicle was in motion all of a sudden my engine shuts off and I lose power. My car won't start and I had a mechanic inspect my car and he says everything checks except for the engine. He says the engine is seized. Kia has tech service buliten tsb for recall campaign for this exact issue. I'm curious as to why my vehicle hasn't been recalled yet. This is dangerous.

I was driving home with my child in the car approximately at 67 mph on freeway 99 North from la to bakersfield ca and all of a sudden car stalled. I was on the fast lane and reacted immediately turned my emergency lights on but cars behind me were so short into rear ending me I cried because I was just shocked and scared for my son. Luckily my aunt was two cars behind me since we had took a short family trip and they helped me out. I had just took my car for an oil change to Kia haddad of bakersfield where they also fixed a recall on my vehicle. This is the third time engine failure happens to this car. The first time was in June of 2017 that's what Kia told me that's why they couldn't replace the because they had already replaced it and was out of warranty the second when it happened to me in 2018. Same thing happened car stalled with my son with me. Mechanic said I needed a engine which he ended up replacing I payed for that. Now this happens again for the third time ? I'm just so overwhelmed I've been so lucky I haven't caused no accident. Now I'm scared to even fix this car again and drive it.
