2016 KIA SOUL- While driving, vehicle lost power, check eng light came on and vehicle would not accelerate, engine started making noise- pulled over and shut car off. Had vehicle towed to independent shop and was diagnosed with bad catalytic (manifold) convertor- they changed oil and filter and also found metal in oil, which I never experienced till this incident- upon research i found that there was a recall on that convertor, i called dealer, had towed there- diagnosed as convertor, was told covered one day, then called next and told it was not. Evidently, looking at reviews and complaints, there are many people driving 2016 kia souls that were not covered under this catalytic recall. Seems that Kia never fixed the original issue. Warning DON'T BUY A KIA- I have contacted Kia customer care, case [redacted] and they have said car did not have recall and are not giving any assistance. …
My newly permitted driver was driving when after crossing highway my car all of sudden was halted to an almost complete stop. the motor stalled in the middle of the highway, thankfully no oncoming traffic was coming. I took the vehicle to mechanic and they said i could have a recall on catalytic converter, called dealership and they state that my car was not in the recall. However my car did exactly what the recall states. now i'm looking at anywhere from 2000-3000 to fix my car is only 5 years old with 75,000 miles. I'm a very dissapointed customer as i was looking to purchase the new telluride however I think I will stay clear from all Kia Products. Concerned Customer LA
The car lost power suddenly while I was on highway I had a semi truck almost hit me it's the second time it's happened and I had to replace catalytic converter twice and I just got it back from Kia dealership in hurst tx it's still making the ticking noise I heard after they replaced the catylic converter the first time they also didn't look into finding out why my Kia soul is using so much oil it burns up fast like in three days from an oil change I'm almost out completely I feel like I would like it if you guys could give me a more reliable car I have a child and I can't keep losing all power while on the highway

Whistling noise and problem with acceleration over 35mph and drifting uphill. Although VIN number did not appear on the listed recall, the repair work recommended and partially completed by Kia repair dealer points directly to the description of an oil consumption problem that includes the 2016 Kia Soul. Some repairs done at Kia [redacted] and some done at Scott Kia in [redacted] (where I reside).
Turning off a highway onto a rural road & without warning my car would not accelerate. Turn off , let it cool, start up and only get about quarter mile until i lost power again. Had it towed to local garage & told its a blocked catalytic converter & very expensive. Kia says its not covered under warranty or recall so now its just been sitting at the garage for over a month while I pay storage fee until i save enough to repair it
