NHTSA Complaint #11534107 — 2017 HYUNDAI SONATA HYBRID

The car started shaking or not running smoothly back in May and then the check engine light came on. I immediately pulled over and inspected under the hood. I saw nothing wrong and the car started fine and check engine light went away. I drove a few more days without any problems but then the same thing happened again. The next day I called the dealership (Bob King Hyundai in Winston-Salem, NC) the earliest appointment was 26 days away. I had no choice but to keep driving it even thought I was terrified every time. It happened a few more times and I took it by Auto Zone and they gave me a DTCs Secondary code of P0303 Cylinder 3 misfire detected No Code(The gentleman informed me that to get a code the light would need to stay on. I told this to the dealership when I took it in for service and diagnosis on 5/30/2023 They called me on 6/1/2023 and told me the mechanic could not find anything and that it could be a vaccum leak and they can clear themselves. About 2 days latter it happened again. I called the dealership back and ask that the Service Manager call me and He still has not called me. I also reported this to corporate Hyundai and that Gentleman stated He could not get in touch with anyone about the issue either. I went ahead and made another appointment which is now scheduled for 8/10/2023. I took it to O'Rielys and they told me the same thing that Auto Zone did Cylinder 3 misfire. I have replaced the gas cap with Hyundai but that didn't help.
