“The engine knocking and check engine light on and stability light for speed control. Took car several times to dealer and they finally told me about the engine need work done to it because they have done all they can do to solve the problem. I paid for them to replace oil control selenoid and the code poo11 still comes up. The car cuts off in traffic.”

“Kia Optima 2011 took a turn for the worst on july 2 2018, my Kia Optima caused me to plummet into traffic after my brake didn't perform l. That's car had been taken to Kia for all service need and car still perform poorly. Have to restart my car multiple time just for it to act right. Car stops one me in the middle of the street one day. I have a 3 old and that day she could have been with me. I lost my license and my money I invested for a safe car for me and my child.”

NHTSA complaint #11001242, filed 2017-06, 93,300 miles

“My car loses power when I use the horn. It happens while parked with the engine on and in traffic. Initially, I thought it was faulty electrical problem because there were 3 active recalls needing to be fixed. I recently took my vehicle to a certified Kia service center to get the recalls taken care of and additonally, had the A/C compressor, struts, and a belt replaced. I also described the issue of engine power loss when I use the horn with service tech and attempted to demonstrate. However, my car didn't duplicate the issue. …”

NHTSA complaint #11360016, filed 2020-09, 95,000 miles

“Vehicle will not start. Engine and ignition replaced due to bearing wear recall. Transmission replaced 2 weeks ago for rebuilt one, and now car won't start. It's been 2 days and Kia has not been able to tell me what is wrong with it. The reason I wanted to submit this complaint is because I believe there should be a recall on transmissions installed in these vehicles. Kia wanted me to wait from 10 sep to mid dec because these transmissions are on back order. Which means there's so much demand that dec is the earliest they could receive it. Their shop is full, mostly of these cars (Optima). …”
