2015 KIA OPTIMA Complaints

My Kia Optima needs/needed to have a software update to the Engine Control Unit (ECU) to installed. The Knock Sensor Detection System (KSDS) protects the engine from excessive connecting rod bearing damage. There was/is nothing to detect the onset of excessive connecting rod bearing wear and alert the driver at an early stage of bearing wear before the occurrence of severe engine damage, including engine failure. There is no indicative code to alert the driver and minimize the risk of a more severe engine failure. My car has experienced this inadequacy and is need of a full engine replacement because of it. There has been recalls on other years of the Kia Optima but, not the 2015. This is an increasing problem amongst Kia Optima 2015 owners and should not be treated separately from the other years that have experienced the same problem. My car jerked suddenly in traffic and came to a sudden stop almost causing me and my granddaughter to be in a collision with oncoming traffic, with no warning. Kia did a safety recall campaign for other models with this problem SC200**1 (Rev 1, 03/25/2021) but did not include the Kia Optima 2015.

I received a Safety Recall notice dated 7/5/2021. When I contacted the dealership, the next available appointment was December 6, 2021. Because of the seriousness of this recall, I feel I should be given a service appointment sooner than December 2021.

On Monday, August 02, 2021, I was driving home from work and suddenly, when I stepped on the gas pedal, the car didn’t move but the RPMs were reveving very high and all the lights, accessories continued to work. The car had to be pushed out of the street and into a parking lot, until it was towed the following morning to my local mechanic. Upon inspection, it was determined that the engine had seized. I was informed that this is a well-established problem of similar models, years of Kia and Hyundai vehicles that occurred as result of an issue during the manufacturing process and that Kia was aware of the problem but refused to issue a recall. Due to Kia’s reluctance to reimburse owners for the repairs, there is a class-action lawsuit against Kia. My vehicle was towed on August 5, 2021 to Bob Rohrman’s Kia dealership on Golf Rd, Schaumburg IL.As a result, I am without a vehicle that I am still making payments on until December 2021.

I started driving to work drove a mile went to accelerate to get on the highway, all my dash lights came on and and i pulled over, my break was stiff so i figured it died, it started to smoke, at first the door wouldn’t open for me to get out, i had to manually unlock it which is weird because if my car is put into park the door automatically unlock normally, when i got out i saw the smoke getting thicker, so i backed up within minutes the car was in flames. I called 911 right away. There was really no warning at all!

I have owned my kia optima for several years and I've had issues with the windshield wipers not going fast enough. I work from home so I do not travel that often but just recently went on a trip & was on the interstate when it started raining very hard. I could not see the car in front of me at all, not even their tail lights. I understand visibility is always worse when it rains but all the other cars were still going at a steady pace & passing me. I had to pull over on the side of the interstate until the rain slowed down to just a sprinkle before I could see well enough to drive. This caused me a great amount of anxiety because i didn't know if I was going to run into someone or if I was even in the right lane. I have several friends that also have the kia optima 2015 & 2016 models and they have said the same thing. The speed on the windshield wipers is extremely slow compared to other cars we tested this on & I feel this is a major safety concern. I pulled up google reviews on this issue & there are a lot of people complaining about the speed not being fast enough.

So we have a 2015 Kia Optima. On June 10 2021 our car was completely fine just did our normal oil change, tune up, etc. it was running and starting just fine. The next day June 11th, 2021 my husband was on the highway and getting off at his exit and the car suddenly went into “limp mode” it’s a safety mechanism on the car to stop it from completely blowing the engine and destroying other things. He was able to get the car home but was only able to go 25 miles a hour. The car is now currently sitting in our drive way throwing a whole bunch of different codes. First it was a rod in the engine and then now a misfire when the car hasn’t moved in over a month. From what I hearing from the dealership and other people this is common with the GDI engines. We are now out of a car and don’t even know what’s completely wrong with it. We’ve barely had a year of that.
