NHTSA Complaint #11510449 — 2014 HYUNDAI SANTA FE

Engine failed, left us on the road. This engine is under class action lawsuit and recall. Took the car to the Hyundai dealer, they said it failed due to sludge that it wasn't serviced regularly, I produced proof of regular service then the claim was denied due to the lack of a knock sensor recall being performed. I never got a letter regarding the knock sensor recall and the previous owner had moved 3 times during the time they owned the car and had no recollection of getting a notice. So a knock sensor recognizes a knock but it locked up on the side of the road, knock sensor or not the motor would have been junk even if the knock sensor had detected the issue. Regardless the engine would have to be replaced. Also this engine is under recall for being a junk engine to begin with so why is Hyundai denying a claim on an engine that they clearly knew they had an issue with. I thought the point of a recall on an engine was to protect the consumer of future issues with the recalled component so why can they get out of doing what is required by law? Also if they can deny responsibility for a recalled item what is the point of having a recall?
