I bought a vehicle from a dealership in 2021. The dealership sold me a 2018 Kia Sportage. To their knowledge, they state they were unaware of any safety recalls. However, fast-forward to [XXX]. As I was entering a busy street (with my two young children in the car (both under the age of 5) and going up a hill, the oil light flashed once and then stayed on, I noticed the vehicle decelerating, as I tried to pull over, making way for vehicles to go around, all three (oil, battery and check engine) lights appear in my dashboard. After one failed attempt of restarting vehicle, I knew I needed to call a tow truck. Thankfully my mom wasn't too long to execute the rescue (it was about 32 outside). The vehicle was towed to the dealership I had purchased it from (NOT a certified Kia dealership mind you). I was told later on that day, that it was a good possibility my engine has blown. I was told the service technician had put over 3.5 qtrs. in order for it to register on the dipstick. I was also told they could replace said engine for a whopping $10,000. Which, the vehicle is only worth $2,000 more than the cost of the motor replacement. I decided to have the vehicle towed to a certified Kia dealership. Where, alas, the engine was in fact, blown. However, per the service manager, the blown engine was due to a recall (XXX) which was in effect as of 1/19/19 (before I bought said vehicle). Per the service manager a vehicle should not be sold with an active safety recall. I then relayed that information to the gentleman who said the vehicle and was told it was illegal for them to work on a vehicle that they are not certified to service (although I had the option for them to replace the engine). I then begin the battle of who is responsible. And ultimately told by the manager of dealership, 70% of the used vehicles they sell have active safety recalls that they do not fix. Nor do they send them to be serviced and checked by the appropriate personnel. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2018 Kia Sportage was burning oil - had to add oil every week. On [XXX] I was driving on the [XXX] and my check engine light came on and the car slowed down. I got to the shoulder this was early in the morning I searched for a dealership and there was one 1 mile away It was 6 am when I arrived to the dealership and had to wait until they opened. And went to DCH Kia and eventually told me it was a cylinder that was blown. Why? Honestly I feel like this may have been a “false” diagnosis since the oil was burning up. I had extended coverage but they said it didn’t qualify for any engine recall. I had to get my entire engine replaced and was out of my car for over a month. Which I’m assuming the cylinder blew because of the oils burning. This should never have happened. And is truly frustrating. Especially when I am a loyal Kia owner and have never had any problems like this before. I was completely overwhelmed with the amount I was charged and that I even had to replace my entire engine and having to get a rental car the entire time as well. I’m noticing from the other comments a lot of oil burning and engine trouble in my make and model. Fortunately I did not get hit on the freeway when my car decided to stop.

Unknown, my Kia has been burning oil there is no oil leak and I had to get my oil changed every 2k miles. Then one day it started shaking on the freeway making noise and I had to exit 30+ miles from my city found the closest Kia dealership I took it there and they said I don’t qualify for the engine recall because it is a cylinder my car is a 2018 it’s 5 years old! There is no reason it should be having problems like this. I have now been out of a car and with a rental for a month now not only do I have to pay to replace my entire engine I have to pay for a rental. Oil shouldn’t be burning up. I’ve never had this happen before. And when I googled it it is a common issue in Kia’s same with cylinder issues. Why would this be happening. Burning oils leads to destruction. Even though I am forced to have oils put in or go to a shop because there is little oil in my car by 1500miles when it should be able to go 5k miles I’m beyond frustrated.

Driving down interstate, mid-morning, and my front sunroof imploded. VERY loud, like a bomb or gunshot. Shattered glass everywhere, all over myself and my car. I jerked, almost hitting a vehicle to my left. Correcting, and almost got hit by an 18 wheeler. Made it over, got off Interstate, was disoriented, ran a stop sign I think. Was the absolute worst sound.

Jul 5, 2023Engine

I am being told my 5 year old Kia Sportage is going to need a new engine. It does have 122k miles, but other than that, I have never had an issue. After reading complaints made by hundreds of other Kia Sportage owners it seems there is a common denominator. A car made with a defective engine. I have been to the mechanic two times, for a routine oil change and have been told there is no oil in my car, even though both times they have stated there are no leaks. I need a solution for this that doesn’t cost me 4-10k on a new engine. When this issues should have never been a thing.

The tow hitch can apparently start a fire. I can not afford to rent a car & must use mine as I am disabled & have a mother with dementia, so I need my vehicle. Kia still has not resolved this issue. This recall has been open since September, 10 MONTHS! This is the THIRD recall for this vehicle, one has a current lawsuit.

Overheating of the wiring harness poses a significant risk of a short circuit and potential engine fire. The problem was identified by the Kia dealer. No warning lamps, blown fuses, or messages warning of the problem. we smelled smoke on a couple of occasions. Unable to afford the repairs, we traded the vehicle in at a Honda dealer.

With the cruise control set at highway speed (65pmh, etc) If you push the foot controlled parking brake it will not cancel the cruise control. The vehicle increases the acceleration to maximum and overrides the parking brake input. If using the parking brake in an emergency you would stomp on the parking (emergency brake) and not be able to slow down unless separately cancelling the cruise control.

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 2018 Kia Sportage Phev Phev verdict →
