NHTSA Complaint #11584674 — 2017 CHEVROLET SILVERADO 1500

We Bought a Chevy Silverado 1500 truck used in Nov 2021for purpose of towing RV trailer. In having axel bearings packed on trailer March [XXX], 2024, the RV mechanic noticed no wear or brake dust. He checked and determined RV brakes had never engaged and found no power to the RV brakes in the plug in port on back of truck. Took to dealer, Chesrown in Delaware Ohio, on [XXX], 2024. After having truck all day they said issue was brake modulator which they reprogrammed. We hooked up RV trailer and brakes still do not work. Hand brake controller on dash will engage the trailer brakes , but not the foot brake. In researching online, there is a great deal of discussion about GM knowing about and not addressing the issue. There’s a known defect in a wiring harness between two of the body control modules. This part is known for broken wires and for connective issues. We reached out to GM Customer service at 800-222-1020, who took our information and said they would contact the dealer. We took truck in today and explained again what the issue was and what we had learned from our research. There are currently several recalls on 2022 and 2023 Silverados for the same trailer brake issues. GM needs to take responsibility for this critical service issue!! We CAN NOT tow a RV trailer WITHOUT BRAKES! When we asked the service manager why the tow package was not part of the inspection process when they took the vehicle in and placed it for sale as a used vehicle, he said they don’t do that. Seems to us, that when a dealer sells a vehicle, all parts should be in working order. Especially with a factory installed tow package. PLEASE research and contact GM and have them issue a RECALL on ALL of their vehicles with factory tow packages to ensure the safety of all of those driving them! You will find numerous forums online where the biggest complaint is the trailer brake system not working and people very frustrated with the lack of response from not only GM but the dealers. THANK YOU! INFORMATION REDACTED PURSUANT TO THE FREEDOM O
