NHTSA Complaint #11513300 — 2022 HYUNDAI SANTA FE

My vehicle has been having intermittent cylinder misfires for about 4-5 months now. Initially, before I knew this was the issue, I didn't think much of it because the shaking that would occur was mild, but as it gradually worsened I knew there was a bigger issue. I will start my car, the check engine light will be on, and the car will shake very hard with acceleration throughout the entire drive. I know that it is a cylinder misfire because I will get an alert on MyHyundai app telling me that a DTC code has been detected, this is the code, "DTC P030100" (the servicing department confirmed this was the misfire code). I have come to learn that the car usually only populates the code when the issue occurs for consecutive trips. As this is an intermittent issue, there are times when I know that the car is misfiring during the drive (it is obvious), but I will not be sent a DTC notification. I have taken my car to the dealership 3 times for this issue with documented DTC codes for each visit. Upon my initial visit to get this seen about, my local Hyundai dealership changed the spark plugs and coil packs in an attempt to fix the issue (although the spark plugs should not usually need replacing at 20,000 miles). It was about 2 days until it started misfiring again. Since then, I have taken it back to the dealership twice because of this unresolved issue, but if the cylinders are not misfiring the day I take it, the issue is dismissed. I truly do not think they know or care to investigate the matter further. I have taken it to the dealership 3 times within the last 3 weeks regarding this issue. I have to imagine this is a safety issue as it can increase the chance of engine failure. Today was the 3rd visit, I picked it up and as I was told, "we saw the DTC code, but the cylinder was not misfiring when we looked at it, so we drove it around a good bit and no issues so the code was cleared".
