Didn’t see this yet so thought I’d add it here. When getting my summer to winter tires (Nokian WRG4’s) switched out on the Premium 2.0 I’ve had for one month as of today, I was told I needed a new ECU under SA352. I’ve not found SA352 mentioned anywhere online. Something to do with the ECU having the potential to throw bad codes related to the fuel delivery system per Kia service. Of course, I didn’t ask why they didn’t tell me about this three weeks ago when I got the car. Sold my Stinger base to Carvana for a profit and got a close out ‘18 Premium. Never knew how many options I was missing. Lol. Anyone else heard about or gotten a new ECU? Maybe I can get them to program it for an extra 4PSI of boost. Not!
