NHTSA Complaint #11464720 — 2017 HYUNDAI ELANTRA

My car started misfiring at about 23K miles. It would bog down on the highway and cars, numerous times, we forced to slam on their brakes to avoid hitting me. Over the course of the next 20K I had to change ignition coils 3 times. At just around 61K I went back to the Hyundai dealer (Nashua NH) and I was told that since I bought the car second hand that the 100K warranty was no longer in effect. I would be fully responsible for everything financially going forward. They said the camshaft position sensor was the problem. They said for $1700 they would take the top of my motor off and "see if we can find the problem". At that point I went to my own mechanic. He changed the camshaft position sensor (that didn't fix it),Crankshaft position sensor (that didn't fix it) and the Vvt Solenoid (that didn't fix it). At this point the check engine was saying that now it was the timing belt that was causing problems. So after spending $3K already it would cost another $2K to change the belt. Well that didn't fix anything either. So now, with almost 3 more years of payments to be made the car is undriveable. In 2 weeks I will be paying to $8K more to install a brand new motor in this car. It is the opinion of my mechanic and of the Nashua Hyundai dealer that the reason I need a new motor is because of all of the issues I have had since the day I purchased this car from Carvana. I had Hyundai America look into these issues and they said if I was the original owner they would have taken care of these issues but since I was the second owner it was only warranted for 60K and I was out of luck. Doing some online researcg there have been MANY issues with the motor of the 2017 Elantra. I have 3 years of payments left and when the new motor is in I will have invested about $11K to keep this on the road. I have documented information if you need it. Please look into these issues.
