NHTSA Complaint #11682108 — 2025 GMC SIERRA 2500

We noticed that the brakes were really soft. We literally had to push on the brakes with excessive force. We took it to Lynch - West Bend, WI for a service call and was told that nothing was wrong with it. After leaving the dealership we did our own research (the hubby is a certified master technician himself). Come to find out through GM, contacts through TBM brakes and Duramax Forum.com "brake pedal effort" we found the issue and a solution and we fixed it ourselves. This truck is brand spanking new and the dealership threw their hands in the air with a safety issue and let us drive out of the parking lot. Imagine driving away after being told no issue to end up in an accident due to failed brakes. Who's to blame for that? Certainly not the customer. It was only when the new car sales manager took the truck for a drive, he agreed that there was a problem. - too late we took it home and fixed it ourselves. This problem needs to be looked into seeing its a known issue!
