2024 Chevrolet Traverse service brakes problems

“1. What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple critical factory components and electronic systems failed or malfunctioned on this vehicle: • Electronic Brake Control / eBoost Software System: The factory brake-life tracking software severely malfunctioned, miscalibrating the braking system metrics. Furthermore, despite subsequent system recalibration confirming over 90% friction material life remaining, the braking system continues to suffer from persistent, severe brake noise. • Exhaust / Emissions System: A premature mechanical failure occurred in the exhaust system, resulting in a loud passenger muffler defect. • Electrical Charging System: The primary vehicle battery suffered from a premature voltage drop/depletion and completely failed standard diagnostics. • Restraint System: The third-row head restraints suffered from a factory defect causing them to jam (subject to active Customer Satisfaction Program N262558680). • Inspection Availability: Yes. The vehicle, its electronic systems, and all diagnostic readouts/replaced components are fully available for physical or electronic inspection upon…”

“When I purchased my car, I was given an alert from the brake sensor that the front pads needed service. I returned the car to the dealer and they were able to reset the alert. A few months later, I got another alert that the front brake pads were at 18%. My car was still under warranty and the brake sensors in the front were replaced, but the software update was not installed at this time. A few months after that, I got another alert that my front brake pads needed to be replaced. I took it up to the dealership and they finally performed the software update. This time my warranty was out, so I had to pay $424 for the software update for the brake sensors. This should be a recall. There is already a service alert: [XXX]”

“Master cylinder failure on interstate caused complete loss of braking. No accident. Shop replaced master cylinder per GM bulletin. Warning light for brake assist failure came on and pedal went to the floor. This could’ve ended in a mass casualty situation, thank god we were in wide open territory and could coast to a stop which took over a mile in neutral.”

“There has been multiple times that the Brake system fails and different codes on dashboard pop up which makes brakes not work and looses power train , the vehicle has to be put in neutral in order to stop on highways and roads which has put my life in danger”

“The Defective Software Trigger: vehicle’s dashboard Brake Pad Life Monitor indicated the pads were low showing 19% roughly 3.5-4mm remaning life. Upon arrival to the dealership, I was informed that my rotors would also need to be resurfaced. I contested a mandatory rotor resurfacing policy. I openly disagreed with this arbitrary "store policy" but was forced to comply to get my vehicle serviced. The dealership stated they would refuse to replace the pads unless I paid out-of-pocket for an unnecessary resurfacing. The technician measured my pads at 7mm (over 60% of usable life remaining). My vehicle did not need brakes; it was suffering from a known factory software bug detailed in GM Bulletin 25-NA-029. Rather than identifying this warranty glitch, I was forced to pay for unnecessary vehicle repairs. The technician machined my front rotors and installed new pads. On my way home, the vehicle exhibited severe, violent steering wheel shaking under braking at highway speeds. The technician completely failed to check for runout or machine the rotors evenly. I was forced to drive 90 miles home with a violently vibrating steering system. I called the dealership but…”

“There was a sent out that GM dealers needed to at no cost provide the software update to several vehicles due to a software issue that puts out an emergency warning that the brakes are wearing and are critically low when in fact they are not. Without the new software vehicle owners cannot manually reset the notification even after changing their brakes. I recently took my truck to David Chevrolet who advised me I needed to pay $193 for this software update which goes against the notice from GM and the DOT. I’m now driving without my brake monitoring system on because the dealership will not update my software. I’m filing a complaint because I should not need my brakes changed again by the dealership as I have already replaced perfectly good brakes because I didn’t know there was a software problem. My vehicle is well under the 36k mile and is only two years old.”
