Kia Optima 2012 abruptly powered down in middle of the busy highway with no check engine light warning. The abrupt loss of power nearly caused a vehicle to hit me from behind. After engine shut down check engine light came on and read code P1326. Car will no longer start.

Engine seized in the middle of the highway. Absolutely not safe at all. My 2012 Optima hybrid is roughly at 115K miles. After seeing all the complaints how's Kia not issuing a recall on this safety issue! very disappointed and hoping to see a resolution from Kia.

Car engine began making increasingly loud noises. Pulled on the side of the road to check it out. Turned off the car then turned it back on and car engine made even louder knocking sounds. Mechanic took a look and said it was a internal engine problem/failure

Optima

We were driving on a city street slowing down for a signal. The car stalled and a message came up saying to tow the vehicle to the dealer. We had the car towed 4 miles to the dealer. No other lights came on indicating any problems.the dealer told us while they were checking for the problem the engine ceased up. Then they said the belt had come off. I think the engine ceased causing the belt to come off.trying to figure out if this has anything to do with the engine problems Kia has been having.

Transmission issues: Between 2nd and 3rd gear. Would lag then jerk the car with some torque once it caught 3rd gear. Had to get 2 replacement transmissions because of this issue. Also engine seizer issue, my engine started to seize when I was going 45 miles an hour with alot of traffic behind me. Then all of a sudden it started making loud thunking noices then a very loud grinding noise and then I was stuck on a road not being able to get above 22 miles and hour, there was no shoulder to pull over. And I was stuck trying to go uphill and all these cars behind me. I ended up having to stop the car and leave it in the middle of a 2 lane road on a hill with the emergancy break on. Kia knew it was another seized engine which I thought it was my transmission again which I had brought in because this 3rd transmission was having the skilling issues around 20-25miles and hour, but after they knew I wasnt going to buy another Kia again they wouldnt fix my trans that should probably be recalled anyways. But they thought it was another Optima seized engine, and even though all Optimas are recalled for this exact same issue, they say that mine isnt covered becasue its a hybrid and has a motor in the car also so its different set up. But theres are others online with this Kia Optima 2011-2013 hybrid engine seizer just like all the other Optimas. And I think the hybrids should be included in the recall. As we are having the same issues. This was a very dangerous issue

I bought a 2012 Kia Optima from autonation in amarillo, tx and I have multiple safety recalls on my vehicle which autonation didn't tell me about at the time of purchase. The recalls can cause a fire and a fatal accident. I've taken it to two Kia dealerships and nothing has been done to the recalls. Kia hasn't fixed or replace the safety recalls. I will not have me or a family member die cause the neglect that Kia has been doing on my 2012 Kia Optima" VIN# [xxx]". I have filed a settlement claim with Kia settlement claim's department "claim #[xxx]". I have taken it to 2 Kia dealership's. I've done all of the steps Kia dealership has asked me to do and nothing has been done to fix or replace the recalls. I use my 2012 Kia for my doctors appointments cause I'm disabled. I lost faith and can't trust this 2012 Kia Optima that im still making car payments. I need this car fixed before me or one of my family members dies in a car accident from the neglected recalls from Kia.
