I just found out by the jiffy lube manager where I go for my oil changes. That my Kia is involved in the oil consumption leak. I purchased it used and still making payments on the car. I have tried working this out with Kia and the dealership with no support or assistance in this matter, So frustrating when they know it’s an on going problem with their vehicles and the oil consumption leak. Really need help with this. I had two warranty on the car and the oil consumption leak is excluded from both. How convenient.

I am writing regarding the KIA recall #SC336. About 6 months ago I noticed my 2018 KIA Sportage w 139,000 started using a lil oil. Then 3 days ago it starting cutting out & ck engine light came on. I called mechanic & took it into his shop. He put a coder reader on it and it said, misfire on #2. He did a compression test and there was 0 pressure on #2 cylinder. He then took a camera and went down and there is a hole in #2 piston. He recommends a new engine. He had me call the KIA Customer Care # however, they basically told me the deadline for class action suit expired and I had no remedy with them. My car was not acting up at the end of said deadline so, why would I have filed a claim?! I seen this info on recall #SC336 as to oil consumption & no compression in '20-'23 Souls and Seltos. I have also seen several mechanics forums speaking about my year of Sportage with compression issues. I am a poor lady on disability and still owe $11,000 on this car w no extended warranty coverage. Is there anything I can do in order to get KIA to include my vehicle in an engine recall ? I have now obtained a loan for the $4,800 rebuilt engine I just purchased from Auto Zone! Thank you in advance for your attention to this matter.

first time I had an issue was in August 2023, my check engine light came on, the car was losing power and sputtering. when I would start the car, it would literally sound like a truck. come to find out, the 3rd cylinder was misfiring due to the piston rings being worn and possibly the coils being faulty and an engine replacement was needed. after going back and forth with the dealer (they had my car for almost a month) the engine was finally replaced. fast forward to last week, it started happening again. same cylinder, same issue. now my car is back in the shop waiting for a new engine (#2). my thing is this....did they use a rebuilt engine, or maybe just fixed the old one and call it new. either way, there is no reason I should need a new engine this close to having it repaired. and judging by the complaints I have been reading, the engines on all 2018 Sportages need to be recalled.

The contact owned a 2018 Kia Sportage. The contact stated that while driving at an undisclosed speed, he observed black smoke billowing from the engine compartment, after which the vehicle lost motive power, prompting him and his wife to evacuate the vehicle in the middle of the roadway. While attempting to retrieve important belongings from the vehicle, the contact stated that he heard what sounded to be an explosion within the engine compartment, causing him to fall backward and sprain his ankle. Moments later the front end of the vehicle was completely engulfed in flames. Local emergency services arrived and were able to extinguish the fire. The vehicle was towed to a tow yard and needed a total loss by the contact insurance provider. A fire report was filed. A police report was filed, but no injuries were reported. The contact later transported himself to an appointment with his primary care physician after experiencing physiological symptoms consistent with a cardiovascular event and was treated for angina.

The manufacturer was notified of the failure, and a case was opened.

Code P0303. Took car to dealer for diagnosis, dealer recommended long engine block replacement due to bad pistons. Kia will not replace. Car has 68K miles on it. Called Kia and they will not even do a goodwill replacement. There is a history of engine failures on my same year and model car but not for this exact reason.
