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.
2018 Kia Optima ex A/T. my wife drive this car to work every day, 45-50 mile round trip for the past couple years. We have noticed that oil consumption is starting to become a problem. Im unsure the exact amount it goes through but it seems to be almost 3-4 quarts between oil changes. Every now and then it would randomly be a quart low, but no leaks, no noticeable smoking, no check engine lights. My wife has had a few times where the car would randomly loose acceleration nad slow way down. The car would come back up to acceleration after pulling over to the shoulder of the freeway when it happens. Im wondering if it might be related to the oil consumption, but not sure. It has the recal for the knock sensor update which we are waiting for Feb 28th, thats the time the dealer can get the car in for it. Our closest dealer is 150 miles from home. We have owned it since new and this is the only problem we've had with it. I hope we can get this resolved. No new car should go through this much oil at almost $6 a quart or more.
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 brought the vehicle into Kia service for the recall including a computer operating system upgrade. After the recall work was done the car driving at high highway speeds failed, and immediately slowed down, almost causing a rear collision. The computer system turned off the drive mechanism and I was left with only the electric motor to propel the car. The car barely limped off the highway. The car was brought to the Kia Dealer and no defect was found and the computer was reset. This problem occurred two more times, at highway speeds (70 mph) and Kia was contacted to find out why the problems occurred and how to fix it. To date, Kia has not responded to how to fix the problem and has ignored all phone calls and emails. The car has been in the shop for 3 months. The problem occurred only after Kia upgraded the software due to the recall. Additionally, the recall work was done. I do not know why the recall work was not reported.
My car is consuming 2 quarts of oil for every 1,000 miles. This falls under the oil consumption that needs a motor replaced and I am getting a run around from the dealership about getting it replaced. They are saying that Kia does not like to replace the motors and I'm better off trading it in. I bought this car intending on keeping it long term, not purchasing a new one. All of the regular maintenance has been done on the vehicle. I've been into the dealership a multitude of times a month due to issues with the car.
The contact owns a 2018 Kia Optima. The contact stated while driving 60 MPH, the vehicle went into Limp Mode. The check engine warning light illuminated. The vehicle was taken to the dealer where the failure was diagnosed as a faulty knock sensor that needed a software update. The vehicle was repaired. The contact stated that after receiving the vehicle from the dealer the vehicle was slow to accelerate and the vehicle was driving sluggishly. The contact stated that the vehicle needed to be taken back to the dealer to be diagnosed and repaired. The contact related the failure to the Kia Consent Order with NHTSA; however, the 2018 Kia Optima was not included. The contact stated that the remedy was not sufficient to remedy the vehicle failure. The manufacturer was notified and a case was opened. The failure mileage was 62,709.
Excessive oil consumption. Dealer says it is normal to burn a quart every thousand miles. At that rate I would have no oil left before my next oil change. That is not normal and could cause overheating and engine lock up. The car only has 45,000 miles.
First incident occured when I was driving to work. The engine made a noise and loss power which almost resulted in a crash. I contacted Kia, they explain to me that a knock sensor need to be installed and software needed to be updated. They installed it and return the car to me. Now again while I am on the highway I hear a loud knock, lights flashing in the car and the car has loss power. I rolled off the exit pull over and called a tow truck. While waiting I check the oil in the car thinking maybe the engine is locking up. There is no oil in the car, which is strange because two months prior Kia just did an oil change. I have documents to prove everything. Kia has been the only dealership that service the car. They now been in possession of my vehicle for four months now and nothing has been done. I contacted cooperate and they have failed to getting back to me after numerous attempts to get answers. Please someone help me. I have congestive heart faliure which I explain to them and I really need my car but most of all I need it to be safe for me.

When driving this vehicle in heavy rain Critical Error Code P1326 comes on limiting the speed to 62 MPH and slow acceleration. This has happened 6 times. Two of those times I took to a KIA Dealer. One said they replaced parts and fixed - but still have issue and one did nothing but download software to get ride of code. The other 4 Auto Store has reset code which they should not be doing and sometimes say no. This has happened 6 times since I have owned the vehicle.
2018 Kia Optima. Consumer writes in regard to illiminated oil light. The consumer stated the vehicle consumed oil quickly, but without any leaking. The vehicle was taken to the dealer to be diagnosed. The dealer suggested driving 1000 miles and then return to the dealer to be further inspected. After leaving the dealer, the vehicle began smoking. The dealer stated it could be due to spilled oiled that occured during the oil change. The consumer continued to drive the vehicle and it caught fire and exploded.
My car has been at the dealership since February 10th. The dealer has been giving me the run around. Didn-??t have any transportation for over two months and car hasn-??t moved since the day I dropped it off. I-??m really getting impatient, as I am making monthly payments on a car that I can-??t even use. Nearing four months and I-??m totally lost on what to do. Thank you for any assistance
Engine overhead and stopped working in addition to it consuming massive amounts of oil without physically putting oil in. I've went to 2 dealerships who refuse to provide me with a new engine even though I'm covered under the engine extension warranty due to me having the knock sensor update done. I am now involving my attorney and will go to the news channels to inform how kia manufacturer has become a disgrace with not providing quality engines in their vehicles and don't want to be responsible for it. there's already a settlement going on for kia optimas and other cars they've made because of faulty engines. They can better believe I'm coming for them next with a lawsuit.
