NHTSA Complaint #11518441 — 2016 KIA SOUL

Previous NHTSA 11498487 for the same issue reported on 12/22. After 8 months of changing the catalytic converter the Kia Soul 2016 de-accelerated in the highway from 60mph to barely 30Mph with a burning smell the check engine light come up and the code once again for the catalytic converter. The catalytic converter was replaced under the warranty from the repair shop on 1/23. Now on 4/23 the check engine light is on again for the catalytic converter again. The repair shop won't change it again. Instead they suggested to bring it to the dealership. Kia dealership stated that my VIN is not included in the recall and they only did theE PI2002A ECU update the rest is not covered by the manufacturer warranty. I've changed 3 times the catalytic converter and the light is code is asking for another one. It's not normal. Major safety hazard for the vehicle to stall in the highway suddenly. Proper maintenance and oil changes are done on time as suggested by Kia. However it burns oil after a new change before hitting the 3,000 miles driven short distances and engine is less than a quart with no leeks at all. Another safety hazard because there's no warning light of low engine oil that could possibly cause the engine to stop and hazard to driver and others.
