I really hate to post this but my faith in customer service has been shattered! I don't know Tdr's relationship with D. C. or even if there is one. But here goes. I have this horrible drone from my truck at 2100 rpm plus. Its posted. The dealer said Star said a turbo problem but I felt that was not totally correct. Anyhow I felt it was purely exhaust. Anyway I stopped by the dealer to ask to set up a meeting with the rep. Had horses on the trailer etc. Was informed the REP was in!Great. It was the operations Rep and was told he'd be free shortly. Setting them up to sell tires. Anyhow I waited over a hour for him to finally appear. Horses in trailer in sun etc. said he had'nt heard of a drone problem but would pass it on to the Tech Rep. I left. Today I was on the phone with DAVE at Wildcat diesel whom was referred by a TDR member and a BANKS salesman. Dave said drone was muffler and exhaust related and found the U. S. built trucks and Mexican built trucks have same down pipes etc but reversed!Mine is built in Mexico. Dave commented he wanted to know if the reverse was by design or by accident and if this is why some drone much louder then others. Set up wrong in assembly etc. I called D. C. to ask them to have the TECH rep call me at his convenience so I could discuss this with him or someone. Was told they WOULD NOT pass this along or pass any message along from them to contact a customer. Had to start at square root one back at the dealer! Claimed they had NO clue to where he would be. I worked DEALERS 25 years. They (the manufacture )can always find their REPS they have his agenda printed in advance. THEY always found them when THEY were at the DEALER I was at . . Just plain refused!Finally got them to admit it wasn'nt they could'nt but they WOULD'nt!. In fact heard the CUSTOMER SERVICE guy laugh that HE would not pass my name and phone number along. IN the morning I will CONTINUE my quest for my request. This WILL affect my customer satisfaction survey.
