2024 Chevrolet Traverse electrical system 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…”

“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”

“A software update caused the warning lights to go on and off despite no issues surrounding the vehicle (lane assist, forward collision warning). While driving on the interstate going 70MPH the forward collision light flashed a warning which then reduced the cars speed from 70MPH to 40MPH within a very short period of time. This is a huge safety concern and no accident happened as there were no other vehicles around at the time.”

“I have a 2024 chevy traverse. Purchased april 30, 2024. One of the 1st ones ever made. The rear windows no longer work. The switch makes a ticking sound but nothing happens. The front windows sometimes work. Sometimes not. And they pause when going back up. I am aware of GM bulletin 25-na-022 which emcompasses this exact failure for 24/25 chevy traverses. When i called GM Marietta told me thar my vehicle was not included in the bulletin. Even though i have the same exact problem listed in the GM bulletin! This is a documented factory part defect and GM is failing to address their failure. This could be a huge safety concern if we were unable to exit the vehicle though the windows if need be. This has been going on for months. My chevy dealership charged me 100 to just look at it and say it needs work.”

“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…”
