NHTSA Complaint #11704816 — 2016 CHEVROLET MALIBU

My 2016 Malibu has a severe EBCM-related safety defect causing all four brakes to drag and overheat (reaching 240°F), leading to unstable handling. This condition mirrors the 2016 Malibu EBCM recall (GM Recall 39440). I sought help from GM. A GM-certified dealer-Monken in Centralia, IL performed a “diagnostic scan” which documented the core hydraulic failure: a constant, uncommanded 6.839 psi residual brake line pressure when the pedal was released. (A healthy system should be near 0 psi) This 6.839 psi is actively forcing the brakes to drag. The dealer ignored their own scientific data and submitted a fraudulent diagnosis of ("rust buildup") to GM, which GM used to deny the claim based on mileage. “Rust buildup” doesn’t create hydraulic pressure. GM is aware of this specific, documented, quantifiable safety defect (the 6.839 psi pressure) and is refusing to investigate it further. I stressed to GM that the vehicle wasn’t safe to drive and that I have a small child who has to ride in the car with me. GM dismissed my concerns by stating the dealership won’t release my car unless its safe to drive. I then had to drive the car 22 miles back home with all 4 brakes dragging. I requested the full diagnostic scan report (that the mechanic confirmed he could provide me with when I dropped my car off there) numerous times and never did I get one. I informed them that I would be filing a complaint hadn’t I received it by a certain time. The new kid in service then did send me screenshots of a generic OBDII scanner where I saw the 6.839 psi. I knew what the issue was prior to taking my car to Monken. I had an independent scan done prior. I only took the car there to comply with GM’s protocol to be eligible for assistance. I am requesting NHTSA investigate GM for failure to address a documented hydraulic control safety defect that causes brake dragging and overheating, which is non-compliant with safety standards. I can give further info Please call me for further details.
