I tried starting my 2006 Jeep Wrangler one morning and when I put the key in the ignition it just rolled over. I remover the lock cylinder and took it to the parts department at my local Jeep dealership. They told me nothing was wrong with it. Upon further inspection they found that the piece connecting the key cylinder to the switch had snapped somehow. They informed me the only way to replace this cheap little piece was to buy a new $400 steering column ( not including labor )and that this is the third one in the last month with the same problem. If that doesn't wave red flags then they, Jeep, certainly have no concern with the quality of their product.
