   Hyundai performed recall #9C2, on 7/2/26. Since that time, the engine has a full time miss. When it is cold, it will hesitate, kick and buck. Hyundai is aware of this. Their solution is to warm the car for 3 to 5 minuets before moving. What happens if there is an emergency and you can't wait? Possible accident with injuries trying to pull into, or cross traffic! I have filed a case with Hyundai, and they just update that they are aware and working on a solution with no…

I returned to the dealership, and they then said additional repairs were needed, even though I had already paid $2,211.57 for the work they claimed was necessary. At that time, my truck had 145,776 miles on it. Because…
