2020 Kia Optima

My transmission failed the week I got it it was inspected by the dealership and I was told that they could not do anything about it I’ve been calling them for a whole year I’ve made notes and complaints I’ve contacted my lender they contacted the dealership to trade me in a new car and was told no I have been out of thousands of dollars paying every month I’ve been ubering I’ve been late to work this is costing me money and my job is on the line

I was driving on the freeway and my check engine light started to flicker and I felt my car shake and going to limp mode. I made an appointment with the Kia dealership and they told me the engine is failing. They submitted a request for a Goodwill case to Kia corporation and it was denied since there’s no open recalls and is not covered by the extended warranty. the dealership recommended me to take my car and keep driving it even though it’s unsafe the vehicle will not go above 50 mph and it starts to shake when driving I have tried to call Kia corporate and explain this situation but they have yet to follow up with me in my case

Out of town July 12th 2025 my 2020 Kia Optima engine started having problems. I tried to get to my hotel but it was obvious I was not going to make it. I pulled into the nearest station and was told my car had no oil. There were no signs of leaking oil and no warning lights so they changed my oil and I was able to made it home. Shortly after I broke down again at night and pulled into a parking lot again no warning and no oil. I had to call someone to get oil and from that point on I had to put oil in my cart every other day with no signs of a leaks and no warning lights. It has become to dangerous to drive and the engine has now failed and knocking and shaking has caused me to park my car and not drive it. I am deeply concerned about the risk of catastrophic engine failure and the potential for fire, which has been documented in similar cases. Despite having the Knock Sensor Detection System installed, my vehicle continues to exhibit these dangerous symptoms. I sought assistance from Landers Crain dealership and KIA; however, they declined to properly evaluate or service my vehicle along with KIA declining according to the KIA Regional Manager. This lack of support has left me with an unsafe, undrivable car and no clear path toward resolution. The Center for Auto Safety Key Affected Vehicles (2.4L GDI) Kia Optima 2011–2018 (some 2019) exact same engine in 2020 Optima Kia Sorento 2012–2019 Kia Sportage 2011–2018 (some 2019) Details of the Recall and Settlement The Problem Manufacturing debris and tight tolerances can cause connecting rod bearings to fail, causing knocking, seizure, and potential engine fires. The Fix Dealers will update the software with a Knock Sensor Detection System (KSDS) to detect rod bearing issues before failure. My Optima has the KSDS installed but failed. Warranty Extension As part of a class action settlement, Kia extended the warranty on these engines to 15 years or 150,000 miles, provided the KSDS update is installed.

My vehicle burns oil too quickly. I schedule my regular oil change based on the feedback from the auto repair shop. During my last oil change he said I practically had no oil left, but it has been less than 5,000 miles since my previous oil change. The tech informed me he's seen this happen a lot within Kia's including the optima that I currently drive. Fast forward a few months i noticed my oil light illuminate for a moment and immediately turn off. I still want to get it checked out just in case so i brought it back to the same shop. They informed me my oil was very low even though, but I still have another 1,500 miles before my next due oil change. He looked around and confirmed there were no leaks or damage that would affect the consumption rate. He highly recommended me look to see if there were any recalls on my specific model of vehicle that would warrant both an explanation and reason for replacement. In the meantime he topped off my oil and i was all good to go.

The contact owns a 2020 Kia Optima. The contact stated that while driving at an undisclosed speed, and while the vehicle was parked, there was a loud banging sound coming from the engine compartment. There was no warning light illuminated. The RPM failed to operate as intended while driving. The vehicle was taken to an independent mechanic, where it was diagnosed, and determined that there were metal shavings inside the engine, causing engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The mechanic referred the contact to a dealer for additional assistance. The vehicle was taken to the dealer; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 69,751.

My car burns oil. I had to have my spark.plugs and engine coils replaced. I was driving and my check engine light came on. Also, my car was sputtering like you wouldnt believe. When i had the spark plugs and ignition coils replaced, the spark plugs were covered in oil. Last year, I got an oil change and within a few weeks the oil was empty. A neighbor told me my car was burning oil. I also took it to an independent mechanic and he said that was an issue with the kia optima.

It either has issues shifting gears like its stuck or the transmission may be slipping, it's had this issue since I bought the car. However I wasn't aware until my uncle drove the car and said something might be wrong.. I have no idea what's causing it. It shudders when I make turn or speed up to pass. Not all of the time but at least twice per my normal trip
