NHTSA Complaint #11523136 — 2017 HYUNDAI ELANTRA

Have had the vehicle throw a code for a misfire 4 times in the 30,000 miles I have driven it. The times I have taken it to Hyundai dealerships in Northglenn and Boulder, Colorado they tried an update and just swap ignition coils to different cylinders. Example misfire is cylinder 3. They swap number 3 and 4 ignition coils to see if they can recreate the problem I the new cylinder. There is already a TCS 20-FL-001h. I recommend a full recall of these defective ignition coils be put out as the problems are still occurring. The problem is reoccurring and the time it takes to get into the shop is 3 weeks out at this time. By the time I get it in the code usually resolves and I have to wait until I get violent shakes and poor acceleration to indicate it is back. Had an accident in January if 2023 and it seemed the brakes were t working as they should. Twice after that the brakes felt as if they weren’t stopping as well as they should. I took the vehicle in and had the rear drum brakes adjusted and that seemed to fix the problem.
