Problems starting a few years ago. Heard knocking, brought it in for recall, and it wasn't doing it anymore. Had problem with emissions. Recall was done and I was told that the problem led to engine problems. Now engine is burning through oil, and local trusted mechanic says it is going to need a new engine by winter. In research have seen others are having similar problems.

Well my 2011 Kia Optima ex stalled in traffic and was able to push it into a parking lot to be towed, come to find out my engine went out on me. I started to hear a knocking noise that came out of nowhere and then my car died and check engine light came on. Come to find out that I have a recall on my vehicle for this problem. I am very uspet to find out this has been going on for a year or so and have never ever been notified of it via mail or anything! I could of killed someone let alone myself or my family! I had to do repairs O N8/19/17 because my car out of nowhere started making a knocking noise and battery died. I had to get a new battery and then have my car checked out which all costed $350 and still died on me and my airbag light is on now then... only to find out my engine was bad. I'm looking into legal action.

First I would like to say that up until now I loved my Kia!!!! unfortunately beginning just before the car had 100,000 miles on it, the car began to burn oil. It is burning approximately 1 quart every 1000 miles. I took the car in to the dealer for the latest engine recall and while there I communicated with the dealership that the car has been burning oil at the rate of a quart every 1000 miles. The dealership changed my oil when checking it for the engine recall, afterwards they directed me to bring it back in at 1000 miles. The car is currently at the dealership now for this check. The car is at 900 miles and a quart low. I hope Kia will do the right thing and fix this. I have read other peoples experiences with the engine failure and one of the common symptoms seems to be the car suddenly beginning to burn oil. I do not want to be on the interstate and suddenly have engine failure in and not be able to get my car out of the line of traffic.

Optima

  • 99,000 miles
2011 Kia Optima recently went dead. While driving roughly 35 mph, the engine seized up with no warnings; no loud noises, no pops. 99K miles on the car at the time of engine failure. Had the vehicle towed to the dealership. Service department then notified me that the engines had been recalled, April 2017. First, the dealership would conduct an inspection, required before securing eligibility for the recall. So I am patiently waiting to hear back from the dealership. I have no vehicle to commute to work. My insurance coverage does not afford rental vehicles in the events of mechanical failures.

While I was driving on the city streets I was preparing to make a left turn and the light was about to turn red, so as I was in the middle of the intersection my car's engine just completely stalled on me and I could not accelerate while my car was slowly rolling through the intersection with oncoming traffic which created a dangerous situation for me. This happened to me a second time again while I was taking a left turn with on coming traffic there was no lights or stop signs posted on this particular road and my car just lost power while I was still in the middle of the road in motion, which caused another dangerous situation for me and the other drivers where they either had to slam on their brakes or quickly change lanes to avoid hitting my stalled car
