Hi! In April, my Yukon was throwing codes P0172 P0175. Local GMC dealer in Louisiana "fixed", by replacing some sensor. Traveled to PA, codes came back on. Local GMC dealer fixed by replacing BCM, body control module in June. Now my check engine light is back on! Power train Warranty ran out 2-3 weeks ago. Also had extended warranty, which also ran out at 5 years, which was Sept. Code onstar says its throwing now is P0430, all of the codes from I can find are related to exhaust system. My question is are these 3 codes related??? Could this be something they will have to fix under warranty, given it's related and has been worked on several times? If not, what does this mean? Catalytic converter bad? Help! My husband is being laid off in the next week. So, obviously finances are tight. Yes, obviously itll be fixed regardless, just trying to plan and cut back elsewhere if needed. This has been a great vehicle! As luck has it, trouble starts when warranty runs out. Really wanting to trade, but waiting on new body Adding mileage if matters, 91K
I've towed my horse trailer with a 2003 Silverado, 2007 Silverado and 2011 Silverado with no issues. I purchased a 2015 GMC Sierra Denali and suddenly was receiving Check Trailer Wiring error messages, WITH dinging bells, over and over and over and over. Had trailer wiring checked, electrician said trailer was wired correctly the problem was 2015 wiring. Few months later, I acquired a 2015 Silverado. Same thing, Check Trailer Wiring, with dinging, over and over. Sometimes you go miles with nothing. Sometimes it starts when you pull out of the drive way. This does not happen when I use the smaller flat plug for my flat bed trailer. Only when using the larger round plug. Took to local mechanic and they could find nothing wrong with trailer or truck wiring. They thought it only happened when brakes were applied, but this is not true. They finally said they could not resolve the issue. The trailer then went to a trailer dealership, that sales the brand of trailer I have. Their initial checks on diagnostics showed no errors. I left, the dinging started, I went back. They rewired the trailer, replaced the brake box and have no idea what else to do. Picked up trailer today. Dinging took awhile, but eventually did start. They asked if I had the truck rewired by the dealership - no. Nothing. It's happening on two 2015 GM trucks. But has never happened in the 13 years I've owned the trailer. Help?
