OK I have to say I did love this car now it is a 3800 lb paper weight. I have been having issues with misfires caused by the EGR valve it is causing a lean out misfire on 3 different cyls at any given time. Has any one else had this issue?
no the egr valve is allowing too much air in the chamber causing a lean misfire. they don't have a fix and I don't qualify for a buy back because I moved from ny to fl. I have a lawyer so we will see where this goes.I think my 2017 (24k miles) is starting to do something similar... intermittent misfire but not setting any codes. I did get to see couple of random misfire counts on #1 (literally 2) using a scanner while it was acting up but nothing consistent enough.
The Kia dealer won't do anything until it actually sets a code because it's so intermittent. When I had time to drop it off with them for 2 days to do all the recalls they claim they couldn't find anything wrong with it.
It seems to do it mostly when it's about half-way warmed up during light acceleration but it's very noticeable when it happens. Throwing a bottle of Techron seemed to fix it for a month or so but now it's starting to do it again. I'm torn between using another bottle or letting it get bad enough to finally flag a code, then fighting with Kia over the repairs.
I think there is a defect in the EGR valve design that lets the injectors get too dirty causing this issue. I saw a post a while back referring to this but I am unable to find any literature backing that up. I'm kind of waiting for an official TSB to get posted so I have something to give to the dealer when it starts to get worse.
With that being said, my wife barely notices it (however me being an auto tech it drives me bonkers when it acts up while I'm driving the car!), and we're still getting 48-50MPG in it.. not bad for a Touring model in mixed driving conditions!
