In the last year, my car has been in the shop countless times. I have had my knock sensor replaced and fixed multiple times. There is a significant lag when taking off from a complete stop, and there have been times that I cannot exceed more than 60 MPH. I have had my car serviced the exact way it states in the owner's manual without fail and still cannot find a cause for why my car is experiencing all of these issues. To get the motor to accelerate is nearly impossible 90% of the time. There is currently a recall on some other 2017 Kia Optimas for the Knock Sensor but there is not one on mine, even though mine has been replaced and fixed several times.

Vehicle had oil change & filter service done on April 27, 2023 for the purpose of hoping the service would rectify an Oil Pressure Sensor Light illuminated on the dashboard. It did not. Sensor was subsequently replaced by the dealer. Vehicle taken into the dealership today (September 2, 2023) for Pennsylvania State Inspection and Emissions, along with another oil change service. Dealer technician in the course of performing the oil change, noticed after he put the new oil plug washer and bolt back in place, a minute crack in the oil pan, itself. He took a picture of it, that I will include with this complaint. Unfortunately, the definition of the photo leaves a bit to be desired. The dealer service writer suggested that too much force (pneumatic socket driver) was employed when tightening the oil pan bolt. I stopped at the location where the April 27, 2023 was done. The General Manager assured me they use a power torgue ratchet and not a pneumatic socket driver. He went under the car and detected a minute leak and said he would forward his report to their Quality Control Department. He asked me if I could bring the car back on Tuesday or Wednesday, September 5th or 6th for a re-inspection. I said I would do that. He did mention there is a possible Class Action Suit that might be filed over Kia/Hyundai Oil Pans and Bolts. It cites the use of poor materials used in the pan construction. Reports range from leaks to the oil bolt plug falling out due to expansion/contraction under duress. Don't know where or when any Class Action will manifest itself, but this oil change facility needs to step up and replace the oil pan, since they were the last ones to do a change before today.

First I had an oil leak which I was advised to warm my car up to prevent from getting worse. At the time I was told it was minor. Then my oil light started coming up every 2 weeks and when checked there was no oil. Now 2 months later, my car has stopped and showed a blinking check engine light. When checked I was told a code of p1326 which is the knock sensor. I have only had my car 7 months and it’s been problem after problem. Not to mention only a month after buying it was stolen. Due to no immobilizer So I’m sure a lot of the issues are also a result of the dumb theif who decided to damage my car. Also my cruise control doesn’t work a lot of the time.

My 2017 Kia Optima is running out of oil between oil changes which I do on time. Before my next oil change it has no oil reading on the dip stick. I just had this occur again and I had to add two quarts. The oil light only blinked on for a second. When I checked it, no oil was reading on the dip stick. Taking it to auto store I was told by worker his mother has the same problem with her 2016 Kia and they replaced the motor in a recall. Mine is a GDl engine. Something needs to be done with these engines. I'm having the same problem a lot of other people are having.

Have lost 4 qts of oil in the last month. Brought it to the mechanic and they couldn’t find any leaks. They said the only way I’m losing oil, is that the car is burning through it. They’ve seen the same issue with these cars. Only 65,000 miles on it.

I only had the car 2 years. In the last two years, I have been getting my oil changed every 3 months. The oil goes out fast. I'm a local driver so I don't go too many places. When I brake or stop, my oil light blinks, when I'm completely out. This month (June 2023) it's staying on. When the temperature gage rises half way the oil light comes on and stays on. I just recently put oil in, so it's not empty or low. Nor is it overfill. I was told it's the GDI Engine. Honestly, idk where the oil is going and why it's running out so fast. And I just learned today a friend of mines KIA is starting to do the same.

The contact then stated that while driving approximately 60 MPH, the vehicle started to hesitate. The check engine warning light was illuminated. The contact then stated that every two days he had to add 1-quart of engine oil. The vehicle was taken to the dealer where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that the vehicle was not covered under warranty, but no further assistance was provided.

To whom this may concern, I have had my car for several years now and the oil consumption is outrageous. I burn 5 quarts of oil every 2-3 weeks. Every time I had taken my car to get oil changes I am told that my specific engine has always been an oil guzzler. Well fast forward to last week. I was driving my car to work when the engine light came on and my car no longer wanted to accelerate. I pulled over and turned the car off. I changed out the battery considering maybe this was the issue. This did not fix the issue. I ended up towing my vehicle to the Kia Dealership in Hurst. I was told that I had 2 broken cylinders and my engine is not replaceable. My question to the service tech was how would my cylinders just break? I was given no answers but a number to call. This number ended up being Kia Consumers who don’t call me or answer the line. I have had the knock sensor replaced which should cover me for any extended warranty that is said to be in place but I am pulled in circles. I need help getting my car through the motions.

This is how I am feeling and the reason for being an unhappy customer. I shouldn't have to keep buying gallons of oil to put in my car every other day. Oil change was done on Sept 6th along with spark plugs put in due to oil consumption. Took my car again to Kia on Sept 21th because there was no oil in my vehicle, so they put oil in. Then on Sunday Oct 2nd I had to spend $44 on a gallon of oil because there was no oil in it once again. It’s a recall and should be fixed regardless if it doesn't shut off while I'm driving, hearing the knocking noise, and or the check engine light comes on. First I was told to bring it or call if the check engine light comes on and stays on now I am told it has to come on and stay blinking. I can be on the highway with my family or infant grandchild and my car shuts off what if I cause and accident, kill someone, or myself or family dies in my car. Would you rather have a lawsuit or fix the problem before that happens. I have talked to other mechanics that have went through it with their customers and they fixed the issue with the Kia's before it gets to this point. Still has of now every two weeks I am buying $44 worth of oil to put in my car. Even from the advisor that I have been dealing with at Kia named Beau stated that my spark plugs issue was from the oil, and he always stated oh its getting close to the motor going out. Now my car is hesitating and its doing the same thing as it was before the new spark plugs except the check engine light isn’t on. I can’t afford to keep putting oil in it and constantly getting oil changes. Just from the receipt the Kia Manufactured attached isn’t the only time that I have been to Kia or contacted the manufactured company regarding this. It took me to take it to a different shop when I can’t stating to Kia the issue than finally they said it’s a recall on the car. It’s also a recall on the fuel pump and I advised them and still didn’t order the part or fix that as well. Still having issues now

Car went into limp mode (three times since July 2022) and slowed down on the freeway from 70mph to 20mph without prior warning, putting my life at risk. Dash reads “check hybrid system”. Kia’s had my car for a week without allowing me a loaner or answers.

I took my car in for a recall, Kia let me leave with an unsafe vehicle. Everything in the recall is happening to my car and it is extremely unsafe. These things were happening before I went in for the recall and after I left from having the recall checked. "Abnormal knocking noise from engine," "illumination of oil pressure warning light." The HEV warning light comes on and tells me to turn off my car immediately which has happened many times in unsafe conditions i.e. being in the middle of the highway in the rain. The check engine light came on but it comes on, then is off, then comes back on. There is a recall for the engine, oil is leaking into the engine on to the hot exhaust which can cause fire to the engine. This started happening not long after getting the car, this is why I brought it in for the recall. I made the appointment right away but the closest appointment was in about 2 months. It continued to happen after they "checked" the recall. The oil pressure light illuminates, the traction control light illuminates, and then 5-10 seconds later a warning comes across the dashboard saying "Check Hybrid system. Turn off engine. HEV!" Now I am being told I would have to bring my car in today, let the car sit at Kia for 4-6 weeks until they can diagnose it, and they will not give me a loaner car. I cannot be without a car for 4-6 weeks, this isn't my fault, and I cannot go pay for a rental car for 4-6 weeks. They are saying I cannot make an appointment for this, which makes no sense to me because I initially made an appointment to get the recall checked. My safety, the safety of my three children, and other passengers has been put at risk because I am driving and all the sudden these lights come on, the car starts dinging, and tells me to turn off the engine. This constantly happens when I am on roads where I can't just pull over quickly. I have been on the highway a few times and this has happened. Couldnt get over immediately and the car was barely moving.

My car is consuming oil crazily and way too often. I just bought this car from a dealership 4 months ago and it is getting worse and worse. Losing power. I’m scared to drive it on the highway due to stories from other people and their kias. I have no choice but to drive it because I have to work. I need help.

The vehicle will shake during acceleration. It comes without warning and will cause the check engine light to flash and stay on for about a minute. It goes away on its own. However, there do not seem to be any stored codes, according to my personal OBDII scanner. The dealer refuses to take it in because there is no check engine light. However, this has happened in several occasions and could lead to an accident. The dealer appears to be waiting for the warranty period to run out.

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2017 Kia Optima verdict →
