Nobody said to lemon law the truck. I mentioned lemon law as a form of peace of mind. My advice was, give the dealership time to fix it, but a buyer does have options just in case this turns into some ongoing problem that can't get resolved in a timely manner. So the point to the OP was, don't panic. If they need to use the lemon law down the road, it's there. I have also seen people use the process to get money back from the manufacturer and keep the car in the end after it was successfully repaired. For me, it's not so much about the misfire, but more so about how long you will be without vehicle. If this is something that goes on for weeks or longer, I know I wouldn't be happy and would start raising hell legally. But hopefully it gets repaired soon and this is all just for conversations sake.
