All connected services do not work. The car cannot receive any updates to software/hardware posing potential safety issues. There was no warning. They all just stopped working. The vehicle was brought to the dealer in the beginning of October 2025 and I still do not have a fix or solution or potential timeline.

Electrical accounts for 21% of all owner complaints filed against this vehicle, across 7 categories tracked.
The failure pattern owners describe
Buyer takeaway: A 2025 Traverse buyer faces multiple serious electrical and safety system defects in the first months of ownership, especially brake failure due to master cylinder issues with parts on national backorder. Critical systems like OnStar, cameras, dashboard displays, and driver assistance features are failing consistently across this model year with no timely repairs available.
The 2025 Traverse is showing a pattern of electrical and brake system failures early in ownership. The most dangerous defect is sudden brake failure—owners report the brake pedal going to the floor, loss of braking power, and warning lights for Service Brake Assist and Service ESC appearing within the first few weeks or months, even under 1,000 miles. Dealers attribute this to failed master cylinders, but the parts are on national backorder with no firm delivery dates; some owners have waited two weeks or longer without resolution.
A second critical failure involves complete electrical shutdown while driving: the engine cuts off without warning, killing brakes, steering assist, hazard lights, and door locks. In at least one case, this occurred twice in a few days despite battery replacement and camera diagnostics.
OnStar and telematics modules are failing frequently, draining batteries parasitically. Dealers are disconnecting these modules to stop the drain, but this disables hazard lights as a side effect—a dangerous workaround.
Other widespread issues include blank instrument cluster displays that prevent drivers from seeing speed or fuel level, rear liftgate sensors falsely reporting the gate is open (triggering constant alarms and disabling wipers), blind spot detection failures, and adaptive cruise control becoming unavailable. One owner's dashboard cameras stopped working after a software update; the dealership's attempt to fix it manually locked the entire system.
A single case reported a broken radiator hose leaking coolant immediately after brake service. Airbag deployment failure during a collision was also reported.

Failure modes owners describe
Brake System Failures (Master Cylinder / ABS / Brake Assist)
Multiple owners report sudden loss of braking power, spongy or unresponsive brake pedal requiring hard pressure to achieve minimal stopping, and illumination of brake-related warning lights (Service Brake Assist, ABS light, Service ESC). Dealers have diagnosed failed master cylinders and brake control module faults. Owners report the defect is widespread and parts are on national backorder with repair timelines exceeding two weeks.
When: Early in ownership, ranging from first few weeks to 4 months; as early as under 1,000 miles
Symptoms owners cite: Brake pedal goes to floor with minimal stopping power; Service ESC warning light illuminates; Service Brake Assist warning message appears; ABS light comes on; Brakes lock unexpectedly; Parking brake will not disengage; Dashboard message 'Brake Assist failure. Press hard to brake. Speed Limited'
Codes mentioned: ABS diagnostic code, Service ESC, Service Brake Assist, Automatic Emergency Braking warning
Repairs/costs cited: Master cylinder replacement required; parts on national backorder with extended wait times (two weeks or longer). Brake control module replacement needed in some cases. One owner reported $214 diagnostic fee.
Recalls/TSBs owners mention: No recall issued. Bulletin N242482170 related to 2024 model hints at recurring issue. Owners report GM declined repurchase in some cases and offered minimal compensation (e.g., 200 reward points). No eta provided on parts availability.
Complete Electrical System Failure
Engine shuts off without warning, resulting in loss of all electrical functions including acceleration, steering assist, brakes, hazard lights, door locks, windows, and OnStar. Vehicle may restart briefly then shut off again. Occurs while driving or attempting to start.
When: Early in ownership; one case at approximately 13,000 miles
Symptoms owners cite: Engine suddenly shuts off while driving; Complete loss of electrical power; Brakes sink to floor or lose function; Loss of steering control; Inability to use hazard lights; Door locks inoperable; Windows do not operate; OnStar system non-functional; Vehicle may restart briefly before shutting off again
Repairs/costs cited: One case attributed to failed battery which was replaced; however, owners report this does not resolve the underlying cause. Another case linked to faulty front-view camera disrupting electrical system, requiring camera replacement.
Recalls/TSBs owners mention: In one case, GM offered 200 reward points as compensation. No recall issued. Dealership testing has not consistently reproduced or identified the root cause.
OnStar / Telematics Module Failures
OnStar emergency services, GPS navigation, vehicle location services, and Wi-Fi connectivity cease functioning. In some cases, the OnStar module causes parasitic battery drain, requiring dealers to disconnect it. Once disconnected, hazard light functionality may be compromised as a side effect.
When: Early in ownership; as early as under 1,000 miles
Symptoms owners cite: GPS and OnStar services inoperative; Vehicle location services unavailable; Cannot connect to OnStar or Wi-Fi; Parasitic battery drain while parked; Battery depletion even with vehicle off; Hazard lights non-functional when module disconnected
Repairs/costs cited: Telematics control module or OnStar module replacement required. Parts on significant backorder nationwide with no eta. Dealers disconnecting module to stop battery drain, but this disables hazard lights.
Recalls/TSBs owners mention: GM escalated some cases but provided no immediate solution or repair timeline. No loaner vehicles offered or suitable comparables available.
Rear Liftgate False 'Open' Condition with Disabled Features
Vehicle continuously reports rear liftgate is open when it is fully closed, triggering a persistent audible alarm throughout drives. This false condition disables the rear windshield wiper and washer, eliminating rear visibility in rain and snow, and prevents the alarm system from being armed, creating a security risk.
When: Began in May 2025, recurring issue
Symptoms owners cite: False 'rear liftgate open' warning when liftgate is fully closed; Continuous audible alarm before and during every drive; Rear windshield wiper disabled; Rear washer disabled; Vehicle alarm system cannot be armed; Loss of rear visibility in adverse weather
