After reading several posts about owners successfully returning their truck under a lemon law. What does the manufacturer do with the returned truck? Are they put back in service? junked? Sent to engineering for evaluation? If they are returned to service after being repaired how does the buyer know about the vehicles history? Will carfax flag it? Same question for flood or hail damaged new vehicles that were on dealers lot, repaired ? sold as new? How does the average buyer protect themselves?
