NHTSA Complaint #11481562 — 2014 KIA CADENZA

The first time anything happened was June 2021. I’d only had the vehicle 4 months. We were on the interstate doing 70 mph when there was a loud noise, it jerked back, almost ran us into an 18 wheeler, went into LIMP mode, and left us on the side of the road! Since then, we’ve taken it to the Kia dealership in Slidell, La SEVERAL times. They removed 5 pages of codes that came up, said nothing was wrong, then it needed a head gasket until finally they said it needs a $9000 motor!! My Cadenza sat at Kia for over 3 MONTHS before they even looked at it the last time! There have been MANY MANY complaints about the head bolts backing out of these Lamba II 3.3L engines causing a catastrophe. Kia does NOT replace head bolts where inserts are needed. It’s an automatic engine replacement. So, now my car is still sitting here in pieces and I cannot get it fixed after paying $9500! Kia needs a recall on the Lamba II engines!! They’re dangerous and are going to kill someone!! This isn’t the first time Kia has screwed me out of a vehicle! I also had a 2011 Genesis I had to get rid of it wasn’t even drivable!! I just want my 2014 Kia Cadenza fixed! Please!
