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.

42 Loud Engine Noise problem of the 2011 Kia Motor Optima

Failure Date: 09/12/2016

2 issues with 2011 kia Optima @ 101,987 miles. Quick burning of oil (causing oil to burn up and having car owner deal with topping off oil levels) and gradual "ticking" sound from engine that results in engine shutdown as car is in motion prob #1: my kia burning thru oil at high temp-I performed each and every oil change paying over $70 for top quality oil. Issue with oil gradually became worse. I had to buy my oil in between changes to keep adding oil to engine, made mistake in blaming oil change companies, wasted time and money in having oil changed sooner then 3,000 miles. Oil can henry stated that they believed kia engine ran on high temp which was burning oil 2x faster then any car. Problem #2: "ticking" sound from engine, that gradually for louder, finally caused engine to shut down (characteristics are deceiving car owner assumes battery issues/ kia mechanics blame bad battery) this is not the case! I have aaa witness my car issues, and car still had issues after new battery was installed, which kia mechanics still blamed battery. Car shutdown is not battery since all inside lights, radio etc still function and when car died during driving it still allowed me to "coast" home at 3 mph. The day my car died, there was already a new battery in car. I came out to leave for doc appointment, car lights came on/radio on but engine barely start, if it did start car engine died, it was as if engine barely started and couldn't maintain itself. I missed a urgent appointment(iam disabled). Called aaa, they confirmed battery at 100%. We tried everything possible, aaa guys said horrible noise from engine, after 20 tries I was barely able to revive it enough to test drive. Drove around my block down the street and after 10 min car died, but not completely. Although I couldn't accelerate, car "drifted" at 2-3 mph. I turned on er lights, coasted home in 1 hour.

Failure Date: 04/04/2015

While at a red light my car stalled without warning. Once off major street we thought it was the battery and after charging for a bit the car did start but made a horrible sound. Had it towed to dealership and they said there was no oil in engine and was due to faulty maintenance which is untrue. My last oil change was 2/2/15 and was due again 4/11/15. My car never gave a check engine or check oil light, I had no oil spills in my garage or where I park at work. There was no signs of trouble. When I asked what caused this to by all standards a new car all they want to say is that is faulty maintenance because kia didn't do the work. My car went from functioning perfectly well to needing a new engine to the tune of kia's price of $6400. 00 they will not honor warranty unless I can produce receipts dating back three years. My car needs a new engine at 63,400 miles? really. . .
