NHTSA Complaint #11472625 — 2018 KIA SOUL

My name is [XXX], I own Kia Soul 2018 and I took my vehicle for an airbag recall and an ECU Update as part of a product improvement on May 7th of 2022. When I took the car out of the dealership store and I was on the freeway, the engine light turned on and the car wasn’t speeding more than 40mi/h. This happened two times, I was driving under the average speed of a freeway with no means to surpass other vehicles and get the freeway exits safety. On the third time this happened, the dealership said they would need to inspect the car and probably ask for an engine replacement. The product improvement activated the P1326 code, this happens when the Knock Sensor Detection System (KSDS) detects vibrations indicating the onset of excessive connecting rod bearing wear. If vibrations caused by bearing wear start to occur, the Malfunction Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed in Limp Home Mode. This was exactly what happened with my car. I sent all the invoices and bank statements to Kia to prove that I was regularly changing the car oil and giving the proper maintenance. Kia sent a letter for costumers that own Kia Soul where they guarantee that vehicles who passed through this product improvement and had the KSDS activate would have the warranty extended for 150,000 miles. However, even though the own dealership said that the noise sounds like a rod bearing Kia denied extending my warranty. It has been two months since I don’t have a car to go to work and neither Kia nor the dealership gave me any assistance on this. Every time that I call Kia, I spend an average of 40 minutes just waiting for someone to help me. My vehicle is 2018 and has 90.000 miles and it is already needing an engine replacement that Kia denies covering under the warranty even though the car shows all the signs that it has a rod bearing failure. What was supposed to be an improvement turned out in a huge injury for me. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 55
