While driving approximately 55 mph, the vehicle produced a grinding noise then lurched a few times every couple of minutes and then the engine shut down. Luckily I was able to safely coast to a stop while going downhill and stop the vehicle at the side of the road. Turned the engine off, waited one minute, then pushed ignition button. Hybrid system started but engine did not. Shifted to Drive, pressed accelerator, but vehicle would not proceed. Turned everything off and waited five minutes. Pushed ignition button and hybrid system and engine started and shifted to drive. Vehicle would drive at underpowered speed and was able to drive 2 miles home at 35 mph. As I drove into driveway, the engine shutdown again. This occurred just a few hours ago, so it has not been serviced by anyone.
Engine, Oct 7, 2021
I was driving on the highway and suddenly lost acceleration, the check engine light began flashing. The car went into limp mode. I got it to an auto parts store and had them put it on the scanner. It is showing code P1326. I have it scheduled to be assessed at Kia. Research on this code with the Kia says, it could need a system update, knock sensor replaced, or the engine replaced. Kia does have a recall out for this issue but my car doesn’t currently fall under the recall. My car has always been mechanically maintained at appropriate intervals by Kia. This is a problem.
Engine, Oct 6, 2021
My car lost power going 70mph and the engine light came on. I had it scanned and the code was P1326. Now my car will not move. This was a reported recall on Kia Optima from years 2011-2014. My car is a 2012 Kia Optima. I called dealership and they said my VIN is not under this recall but I am having the same exact problem as the recall reported in 2018.

My wife had been complaining that while driving 2011 optima hybrid at highway speeds the car would suddenly lose power and slow to 30 or 40 mph while the pedal is floored. Took it to the dealer who said we needed a new battery which did not solve the problem. 2nd time came with a warning on the dash to check hybrid system, back at the dealer they said it appears to be some special fuse in the trunk ($300)…problem sill persist however this time the car completely shut down on the road, dash was lit up like a Christmas tree. Had to get it towed. Now dealer says its the HPCU and that’s going to run almost $6000. Dealer was willing to install a used one i got on EBay, they charged $1300 for the install they tell me the problem still exists.

I was coming home from work doing around 75 mph on cruise control when all of the sudden the car jerked violently and lost all power, the car behind me would’ve rear ended me if they weren’t paying attention. I just hold the throttle down to get home, misfiring terribly, and the best way I can describe, it smelled hot if that makes sense. I had it looked at and was told it doesn’t have compression in one of the cylinders and that it wasn’t covered under warranty or recall. So now I’m paying for a car that I can’t drive.

I was at a stop sign when my car shut off. Now it won't start. Took it in to check it out and found out that the motor seized up. I know that there is a recall on the engine for the same problem on other models. Not safe to be driving the cars. Could cause a major accident resulting in possible loss of lives. This model needs to be recalled before this happens to anyone else.

I purchased 2012 kia optima hybrid june 14, 2021. 1 week after I purchased vehicle i started to hear "clicking noise" & felt a "bump" each time I moved steering wheel slightly left or right. example moving steering wheel to change lanes, turning vehicle left or right, and moving steering wheel when straightening out car when parking. As of 7/6/2021 "clicking noise" in steering wheel/steering column is louder.

Driving at 60 mph on the highway engine seized up with no warning what so ever no engine light or oil light. Once vehicle stopped checked oil and it was almost empty. No warning of oil pressure or oil low. Vehicle always inspected an oil change done on time. Can't find recall on my vin but other 2012 models had a recall for this exact reason. I was almost hit by a semi when the vehicle just died with no warning at all and everything locked up. Never had 1 issue with this vehicle until now. And I am worried kia will not fix it when clearly other optimas of the same year had the same issue. I can't understand why when vin search it doesn't show this recall. It's all over the internet.

While in cruise control hitting the breaks resulted in the car not wanting to slow down or stop. Had to go off road inorder to not hit vehicles in front of me. I turned off ABS and this issue isn't there. I have no warnings for my ABS system and this doesn't happen often. However it's getting worse now this is the worse it has ever been.

Oil changed every 3000 miles. Driving to work the other day check engine light came on. Car went into limp mode. Pulled code and it was for rod bearings. Supposedly rod bearings had been repaired by recall before. Car only has 91,000 miles on it. So shouldn't need another set of rod bearings if previously replaced.
