2020 KIA OPTIMA Unknown Or Other Problems

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 caught on fire in gallipolis ohio after insurance paid to fix car it continues to leak oil stall and is dangerous to drive12/24/2022

The turbo system on the car burns oil at a rapid rate. Had to pay $4000 to replace and still continues to give me problems and check engine light. Violates lemon law. Had replaced in September but was giving me problems well before and finally took it to the dealer for repair

Car burns oil at significant rate which ruins the engine

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.

by the time i’m due for an oil change the car has no oil. there is no leak and no smoke to show car is burning oil

Dealers claim pistons are bad and engine is stalking eating through 2 quart every thousand miles or less. Properly maintained and everything not sure why the pistons would be bad already, also replaced a pcv sensor to fix problem but did not change anything.

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.

The contact owns a 2020 Kia Optima. The contact stated that while driving at an undisclosed speed, the automatic braking system engaged without warning to stop the vehicle. Additionally, the cruise control failed to operate as needed and the vehicle intermittently failed to turn on while using the "Push to Start/Stop" button. The vehicle was taken to the dealer and Kia of Cape Coral (404 NE Pine Island Rd, Cape Coral, FL 33909) however, both dealers could not duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 7,500.

Mileage: 7,500

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.
