NHTSA Complaint #11610710 — 2017 HYUNDAI SONATA

I had the engine replaced in Feb of 2024 which was covered by the engine replacement recall. In May of 2024 I started having issues with my check engine light flashing on then off. The engine will lose power briefly during this time and the engine shakes. It feels like you are going to lose control of the vehicle when this happens. This has happened approximately 3 times at freeway speeds and a total of approximately 15 times total. I have taken it to the dealership 3 times for this issue. They made us pay for spark plugs that were fine when the engine was replaced (3800 miles was driven between the engine replacement and this issue starting). The dealership has now had the vehicle since the middle of May said they can’t recreate the problem but are saying it is a fuel pump. This was also fine when the checked it when the engine was replaced.
