My 09 SEUC last week developed a noise in the front cylinder that can best be described as beating on a trash can with a hammer. Dealer picked it up, and when they tore it apart found that the roller on the lifter failed, and then damaged the bore and basically everything. The motor company told them to pull the motor and the company is shipping a new one to be installed. I had 22500 miles on it, had recently had the 20000 mile service performed and everything was going fine. The only good thing, no hassle with motor replacement from company, and when I called the company's customer service number they told me they would expedite the shipment of the motor. I have a several state trip planned for the end of the month, and hope to still be able to make it.
