duramax exhaust systems
well I am new at this so please excuse any mistakes and correct me if necessary. I have a 2011 duramax and I bought it new. it has 40,000 miles on it and the exhaust has failed to regenerated its self 5 different times. It goes into limp mode and it never fails I am 50 miles away from any dealer and have to drive at 35 mph. Has any other Silverado owners had this problem?
