My Kia was making a whistling noise on and off for awhile then my oil light would flicker so I figured I need an oil change. Got my oil changed and then the car started make a knocking noise and would get worse with acceleration and would have a hard time accelerating. It would jolt and vibrate and make knocking and flapping noises. Turn on my road to go home and lost power. My car slowly came to a stop I could not accelerate at all. My engine, battery, oil, and eps light came on. I tried starting it up and would come on for about 5 seconds make a lot of noise and the engine would turn off but my radio and windows still worked. My ac was on but not cooling. All the cabin lights work still but my brake are stiff.

2011 Kia Optima. Engine seized while driving on the highway. Almost crashed. Swerved off the road, it made a funny noise under the car and then I had no control and the engine died. I just had the oil changed and the mechanic said the oil was black. It sucked up all the oil causing this to happen. Very dangerous. Never received a recall or letter anout this. Two weeks in the ahop and still no engine.

I was on interstate 65 I was going about 55mph and began to accelerate when the vehicles engine stalled. There were cars coming from behind I quickly got over into the emergency lane and came to a stop. There were no warning lights that came on prior to this occurring. I never heard any type of knocking from the engine either. It was a terrifying moment having the car stop for some unknown reason. 4 days later there as was an announcement of a recall from Kia regarding the connector rod. I have been told the motor is locked up but no one has told me why. Kia corporation has been slow to respond. They have said that its not an official recall until the end of May. They have provided me with a case number but the case specialist has yet to call me back.

Vehicle sized on the hyw while approximately 65mph. It was towed to Kia, who stated they would replace the engine with a new one. However they replaced it with a manufacturer or modified engine. My car now vibrates and has inconsistent fule injection. I have reported to this to the service manager and to Kia corporation. I have yet to hear back from either about correcting the issue.

Engine seized up on me without warning while driving, engine light etc, on I-10 November 2016, contacted Kia case # K3330321 had me tow the vehicle to them for warranty extension work for the engine connecting rod. They then told me it was out of warranty and would not repair vehicle. I canceled plates and it is still sitting in my yard unrepaired. Even had the case escalated higher up with Kia with no results. Only incurred more cost, they estimated me $7000 to replace the engine.

"engine seizing recall" Kia recall number is SC147. I was driving down the interstate about 70 mph heading to jacksonville Florida from valdosta Georgia and the car begin to decrease in speed then as it decreased speed I pulled over and good thing I did because the wheel locked. I tried to start the car but nothing would happen. I was in the car left lane when the car begin to decrease in speed and as I tried to pull over there were cars passing and I was almost hit not only from behind but on the side because the car could not be driven fast enough to pull off the road.

Engine seized without warning in the center lane of the highway at 65mph. Luckily, I was able to coast to the shoulder without incident and wait for a tow truck. Had it towed to the repair shop, who confirmed that the engine was seized and needs replaced. Kia knows about these engines having a problem yet continues to leave them out there. It's a matter of time before someone is injured or killed when their engine seizes at highway speeds and they are unable to safely get to the shoulder.
