Purchased 2017 Kia Optima from DriveTime in 2021. Car burns a lot of oil, as I am constantly getting the oil changed or adding oil. A few months after purchase, all of a sudden it loses power & decelerates while I-??m driving on the interstate. Had to pull over & let car sit for a few minutes. Every 10 mins I had to do this. Had it checked out the next day at Kia dealership & was told nothing was wrong. I let the car sit for about a month b/c I was afraid to drive it. Finally decided to drive it & the issue seem to resolve itself. Now almost 6 months later it happens again. Car wouldn-??t accelerate over 40 mph. Car warranty agent advised to take to Firestone( in-network repair shop). Mechanics say the engine is gone & they called warranty company, & then they say take to Kia dealership. Dealership states if it-??s the engine there are 75 cars with same issue ahead of me. They ran diagnostics 2 weeks later & said it-??s not the engine but gave me a long laundry list of other issues. Said new wiper blades needed (not true, the new blades were just put on 1-2 months prior, said oil change needed, but that was fine 3 days before I took it to them, & more issues with a invoice total of over $6500!! They kept my car over 2 months with no call to update me after I advised everything they said was wrong actually wasn-??t. I called daily & left messages with no return call. Finally got someone on the phone in the Service dept & was told it still isn-??t the engine but just needed a software update. I still don-??t trust it & afraid to drive it. But yet & still the VIN # is still not on the recall list. Regret the day I walked on the DriveTime parking lot. Nothing but issues from day 1. Too bad I couldn-??t list them all here.

I am the second owner of this car. According to carfax it has been well maintained at kia since day one. I have owned it for almost 6 months and it has been sitting at the dealership for 2months due to engine failure. There is a rod knock and sludge build up not for lack of maintaining it but from not being driven enough. I am being told it is a $16,000 repair. These cars are warranties for 10 years 100,000 miles (it only has 72,000 miles on it) but since I'm not the original owner that warranty doesn't follow. This is a misrepresentation.

ENGINE MALFUNCTION: It is available for inspection at Lee Kia, Greenville, NC On January 20, 2023, my car experienced a blinking Malfunction Lamp (MIL) when I was out of town at an appointment in Williamston, NC, 16 miles away. This is the indicator, when blicking, warning for the Knock Sensor Detection System software that was put on my car on December 20, 2018 that the engine is malfunctioning. After my appointment, I drove the car one mile to AutoZone in Williamston, NC and they plugged in their sensor and got the P1326 code. While at AutoZone, I called the Service Center at Lee Kia of Greenville, NC and reported what had happened. They told me not to drive the car and have it towed to them, 1 hour away. My tow service would only allow towing ? mile to the Dodge Dealership. I called Lee Kia Service Center and talked to a [XXX], Manager of the Service Center. She said it had to go to a Kia Dealership to be covered under the Engine Replacement Recall. On Saturday, January 21, 2023, I called the Service Center at Lee Kia and asked for an update on the car. The Service person told me that it had arrived and they would diagnosis it either that day or on Monday, January 23, 2023. On Monday, January 23, 2023 in the early afternoon, I called Judith the Manager of Lee Kia Service Center and asked for an update on the car. She told me it would take 4 months to diagnosis the car and I would not be able to have a rental car until it was diagnosed. When I asked why it would take 4 months to diagnose my car, she said she had 15 cars ahead of me. She said she only has two technicians that can diagnosis and it takes one day to diagnose a car. The mathematics of that did not add up. My car should be diagnosed in 16 business days, not 4 months. She refused to help me.

Engine oil consumption: I have owned this car since November 2022 and took my Kia Optima to Valvoline for an oil change in December 2022 because my oil light came on and it turns out that my car was 3 quarts low and they topped my oil off for me. 1 month (January 2023) later my oil light in my car did NOT come on but the check your engine light did and it seemed like it was losing power. So in order not to damage the engine I had it towed to my home when we arrived at my home oil started coming out of the car at the bottom while it was still on the tow truck lift the car was facing down hill

I took my Kia Optima to Century 3 Kia for an oil change in August of 2022. 2 months later my oil light comes in my car but I still have 2000 miles left until next oil change. I called Century 3 Kia complaining of a flashing oil light. They told me since I still have 2000 miles until the next oil Change, the mechanic must-??ve just forgot to reset the car after they did my oil Change and that-??s why it-??s flashing. They told me to come down so they can reset it. They reset it and sent me on my way without even checking my oil. After leaving I still had the oil light on so I took it to a mechanic close to home to check my oil and I barely had any in there. I topped the oil off and the light went away. I sent Kia consumer an email after this visit complaining of the bad service I received and how they made me drive with no oil. I attached the email. I then scheduled an appointment at a different Kia dealership - South Hills kia for a new oil change and told them to please check my oil because I believe it could be burning. South Hills Kia performed a multi point inspection and gave me an oil change and told me my car had no signs of leaking or burning oil and is good to go. Not even a month after the new oil change my engine blows and the dealer told me it-??s because of burning oil and I-??ll need a whole new engine. My car is a 17 Optima with 61,000 miles and just a mout of warranty. It-??s always been up to date on oil changes. It-??s upsetting because I trusted Kia and now my vehicle is down because of them and they want me to pay.

I am a service provider. On 9/15/2022, a customer, who owns the vehicle with attached VIN, came for an oil change in his 2017 Kia Optima. On 11/11/2022, after nearly 2 months and 2,964 miles, the customer and vehicle owner called to tell us his car was broken down on the side of the road. Upon inspection, it was found that the oil drain plug had fallen out of the vehicle after nearly 3,000 miles. As a result, there is engine failure on the vehicle. Due to the mileage, we went to Kia West Broad in Richmond, VA to ask for their opinion. They were unwilling to assist the customer. I believe this falls in line with the current investigation from the NHTSA into Kia drain pan assemblies and drain plug issues. I have repeatedly been hung up on by Kia when asking them questions surrounding their willingness to assist this customer who is without transportation. Each time that I ask about the investigation, I am put on hold and then hung up on.

On June 5th 2022 as I was traveling out of state with my wife and daughter the car lost power on the highway. I pulled over to the side when safe and noticed whitish grey smoke puffing from under the hood by the hinges. Being a fire lieutenant, I recognized this as the car being on fire. We exited the vehicle, my daughter was asleep in the back seat, so it was a panic to wake her and make sure she got out away from traffic. Within the 3 minutes I was on the phone with 911 the car was engulfed. A few minutes after the first Chief arrived the fire had reached the fuel tank and the vehicle exploded, approximately 8 minutes in. I opened a claim with my insurance and with Kia America. Kia has taken the blame but refused to replace the vehicle, instead offering me $15000 for the car with only 57000 miles on it. After fighting with Kia for 3 weeks during my claim they finally provided me with a rental vehicle paid for by their insurance. To this date they have not paid for said rental and I am now on the hook for the $930 charge. This event has caused much undue stress on me, I already have cardiac issues, my wife and daughter still have nightmares from the event. Kia inspected the vehicle which is totally burned, they found it to be an engine failure causing oil to spill onto the hot exhaust. They accepted blame. There was no warning, no noises, no lights. I never received a recall notice, I found out about the recall from my insurance after the fact. Kia has been less than helpful.

For the past 5-6 months I-??m have ongoing issues with my engine and excessive oil consumption. I-??ve completed the three oil consumption test per 1000 miles. On the last test(3rd check), I was told I passed and nothing further was needed. Approximately 1 month after that my engine light illuminated and my car violently shook upon acceleration and while sitting idle. Was informed it was my spark plugs and electric coil-?? oh and a routine oil change, which I paid to have repaired at approx. $650 this was in late August/Early September. Now here we are in late October and my oil lamp is on yet again! My car does not achieve speeds no higher than 50 mph. I-??ve been to the dealership 7 times since April 2022. There-??s an expense with owning cars but this is ridiculous. I-??m currently a few hundred miles shy of 80,000 miles
