Car is consuming oil every three weeks. Engine is going to burn if it does not stop. It’s not in a class action but probably should be. It’s been 4 months and over 1,000 spent.

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

Engine has been burning oil for at least a year now. Cause ignition coil/spark plug failure and have replaced all 4 coils and plugs 3 times now within a year. Engine will randomly start to sputter after about 3-5 months of replacement. Adding a quart of oil every 1-2 weeks. No leaks and no smoke, just money down the drain.

Immediately after getting Kia's latest recall "Voluntary Emissions Service Campaign" software update, my transmission began to Hard-Shift between neutral and 1st gear, and when slowing down, from a gear to a neutral position with the transmission. The car has lunged a few times when going from neutral to 1st gear position--concerning. This is most noticeable when car is cold, but is still always noticeable. Stop-and-go traffic it's also most noticeable. I have notified local dealership by phone message and email but have not heard back in 2 weeks.

2020 Kia Optima LX 2.4, LESS THAN 100,000 miles on car. Car started over consuming oil 2 quarts/1,000 miles. Cranked engine yesterday to go to work and serious knocking sounds, engine is rattling severely. Losing revving power, undriveable. Smoke coming out of exhaust that smells like rotten eggs. Will be taking this to get codes run but I believe this is due to Theta II engine failure issue reported in similar cars with the same engine. KIA NEEDS TO COVER THE 2020 OPTIMA UNDER LIFETIME WARRANTY PROTECTION otherwise this is a $10,000 cost to replace engine.

2020 Kia Optima Exploding Sunroof. While driving home from work on the highway I heard a loud pop that startled me. Once stopping I found my sunroof was broken. Nothing had hit it, and after inspection at the dealership no mechanical issues were found. On Google many other Kia owners with different years and model cars have experienced the same exact thing I went through. On top of my monthly note I have never been late on. I have to pay to get this fixed when Kia should have actually footed the bill. Will never purchase another kia after this. The whole situation has caused tons of stress and anxiety.

When I accelerate the car jerks as if is going to cut off. I have taken it to the dealer, and they can not find any thing wrong. After searching the internet, I find I am not the only one with this issue. I just want my car fixed so that I feel safe driving it.
