I need for some help. Since I received my Vision line Reefer the sound has worked sporadically. As you can see from the video I just received the car back from Lionel to fix this issue and I'm still having the same problem. After the video I powered down the track and grabbed some dinner. After dinner I powered the track back up and the reefer was working perfectly. This morning I tried it again and the sound was not working. What should I do? This is very frustrating. I've already spent $60 shipping this car back to Lionel 3 times for the same problem.
