My truck has been in the dealership 3 times in the last 4 weeks for an engine light on that OnStar advised was due to emission sensor problems. The dealership does a diagnostic each time saying everything checks out ok and nothing is wrong until this last time I took it back then they figure that its the sensor in the DEF tank. I just talked to the dealership and found out there are 3 other trucks in their service department and currently 55,000 trucks nationwide with the same issue. They say that there are no replacement tanks available in the country. I am driving a loaner 2016 Tahoe but need my truck to pull gooseneck horse trailers, hard to hook up a 35 ft. gooseneck trailer to a Tahoe!!!!!!!!!!!!!
