I'm having the same problem with my Tin Lizzie. I bought it in May of 2010 and the longest it has ever worked at one time is three weeks. The dealer sends the repairman out and they replace the encoder and it works for a few days and does the same thing again. I have called the company and left messages for Greg the repairman there and for Ernie the owner and get a return call about every 5th message I leave. Ernie did call me back once and said he would send a part the next day but then the dealer called and said they wouldnn't replace that part. I usually have to wait 2 - 3 weeks for a service call as I have been told they're too busy to keep coming out - I live about 10 minutes from the store.
