Excessive oil consumption 1-1.5 months approx. 1,000 miles into new oils change. It is available for inspection. Safety was put at risk due to not knowing there was no oil in my vehicle while constantly driving it as it did not display the oil warning sign on the dash board. The oil change dealership has confirmed an oil consumption issue two separate times. I am familiar with multiple people having this same issue with Kia and hyuandia vehicles. The dealership is requiring multiple steps to be paid out of pocket prior to using the full warranty i purchased to cover the issue even though they know what the issue is and how to fix it.

While driving down the road the car said it had a major voltage failure and was shutting down. I was in the middle of the street and thankfully was able to coast to the turn lane before the car came to a total stop. since the gas pedal didn't do anything. the car then said there was multiple failures and the hybrid system needed to be immediately shut down. The car then wouldn't start or move after that. about 20 mins later the car like dashboard and screen would turn on but the engine would not. when it turned back on there were even more warnings along with other failures like emergency braking and transmission and the hybrid communication. when the tow truck came and took it it would go into neutral to get on the truck but wouldn't even do that when we got it to the dealership it had to be manually taken out of park to get it off the truck. there were lots of warning lights but the oil, engine, and another light I not sure what it meant were always on even when the others would go away after a while.

At around 40,000 miles my car started burning oil rapidly. No leaks were found and I would get an oil indicator light then the car would shut down while driving. I couldn-??t get it to accelerate. Mechanic said Kia-??s and Hyundais have been having those issues. I have needed oil changes every 3 weeks to keep in functioning.

I got out of my car to talk to someone and my car was running With my purse and phone in the car and the trunk open.i was meeting someone to buy a vacuume from Facebook marketplace. I decided to put the vacuum in the back seat instead so closed the trunk. When I went to open the door all the doors were locked. I was locked out in the rain for an hour. The person I bought the vacuum from called kia and they sent someone out to unlock my car. Several people have said the car is supposed to recognize that the key is inside the car and not lock it. And that this is an issue. I do know it has only started doing this recently because I live 8n the country and never lock my car in my garage. And recently I have noticed it is licking itself now every time I get out. So I have been leaving the windows down at home but it was raining today when I got out and I didn't think about or remember that it is locking itself.... Also I have never gotten out of the car to get something with it running and the windows closed since this issue came up.

My car was stolen

- Cleveland, OH, USA

Hello, My Kia was stolen lastnight. The criminals apparently the -??KIA BOYS-?? took my car, it wasn-??t until after I spoke with my daughter she expressed to me that she saw a video on social media about Kia-??s and another car, being stolen excessively. So after doing my research I was sent to this page to share my story. I am sure Kia is aware of the situation, so much so to where they are/have made a change in their 2022 model. But those of use who have a Kia model that is not a 2022, we are screwed. I make monthly payments on a vehicle engineered by adults, but what I-??ve just found out is the criminals are mainly middle school age children who takes the cars for a joy ride. It is hard to process this oversight by Kia, I love my car, I-??ve had 2 Kias. But this will be my last. Especially if they (Kia) doesn-??t own this oversight. To have my car stolen hurts, I didn-??t leave the key in, nor the door unlocked. I parked my car, activated my alarm, only to wake up and my car gone. I see there is a lawsuit in a state (I forgot the state) against Kia. I hope and pray the state of Georgia can start one as well. My car wasn-??t the only Kia, taken lastnight. There were 3-4 others taken from this complex.

Me and my family just returned home from the laundry mat and took 2 children inside our house and turned around for our belongings and clothing/bedding for the family as the wheels spun out being followed by a silver hyundaii. Just a matter of seconds to 2 minutes. The keys were not in the vehicle. 2 childrens carseats and almost ALL of my family's belongings were stolen inside of the vehicle. 2018 kia optima dark slate grey in color with dark tinted windows and sun strip at the top of windshield, black rims.

I purchased my Kia optima brand new I believe it had 7 miles on it when I purchased it, shortly after it was purchased it started having a problem with the transmission, I would go to takeoff and it was lunch and jerk pretty hard to where it was very noticeable. I took it into the shop they thought that it was something a computer program could reset they performed that I did not fix it, I don-??t drive my Kia very much I barely have 25,000 miles on it right now I am a real live in care provider so I don-??t drive very much my job is at home. I have taken the car into several dealerships repeatedly to have it fixed, IA really was at a loss and did not know what to do because I had taken it to two different dealerships and the problem was never resolved. I contacted an attorney they got nowhere because apparently I needed to take my car in one more time within a timeframe for them to be able to do anything about it? And any right, still to this day the car does the same thing it-??s been in the shop four or five times for this problem. One time I took it to Kia and Elk Grove they kept it looked at it said they couldn-??t find the problem. Every time I-??m renting a car paying for the insurance going through the inconvenience of renting a car paying extra insurance etc. just to have nothing done with my car. When I went to pick up my car from the Elk Grove dealership I threw a fit because I was tired of it and I said look somethings wrong with the car I-??m not a mechanic I can-??t tell you what it is but I need this car fixed, the service manager came out and said I-??ll take a a ride with you and we-??ll see if maybe I can see what the problem is we didn-??t even get out of the parking lot and it jerked so hard at the service manager noted it in the file had me drop it back off and leave it it-??s still wasn-??t fixed. I took it in again after that the new service manager took it on an hour drive on the freeway hooked up to a computer with Kia and of course it didn-??t do anything while h

While driving at highway speed my children (11, 7, & 5) and I were almost rear-ended when my Kia Optima 2018 (79k) without ANY warning loses power, jerks and then regains power. A number of vehicles behind us had slam on their brakes to avoid a pileup. My Optima almost resembled the feeling when a vehicle runs out of gas but much more abrupt. The drink my son was holding was thrown out of hand due the vehicle jerking to an almost stop and jerking back to power. No warning light, battery & alternator both test good and tank was half full. Two days pass and the same system fail while driving with the same similarities (no warning lights). My Optima is no longer under warranty and I have no financial resources for repairs.
