When the auto stop-start system reactivates the engine upon acceleration from a stop, it causes a noticeable stumble or jerk.

The alert chime for the auto stop-start system continues to sound even after the feature is disabled via the button.

The Tire Pressure Monitoring System (TPMS) sensors repeatedly lose connection, requiring owners to perform a manual relearn procedure each time.

The heads-up display (HUD) flashes red warnings randomly without any apparent reason or issue.

After locking the vehicle, interior lights unexpectedly turn on without any input from the owner.

The GMC Acadia's large infotainment screen runs Apple CarPlay or Android Auto, but these interfaces only use a portion of the available space (e.g., 70%), leaving unused areas and inefficient layouts ...

The infotainment system's volume controls, including the knob, steering wheel buttons, and side buttons, become unresponsive, making it hard to adjust audio levels.

The vehicle's wireless phone connection for hands-free calling or media occasionally drops, interrupting use.

GM sells detailed driving data from OnStar-equipped vehicles like Acadia to LexisNexis, which shares it with insurance companies, potentially raising owners' rates based on driving habits.

GM shares collected Acadia data including location and personal info with third parties like marketers, affiliates, dealers, law enforcement, and service providers beyond emergencies.

The Acadia vehicle and myGMC/OnStar apps have cameras and microphones that can access audio, video, voice commands, and biometrics, raising concerns about constant snooping.

Owners cannot delete their collected data from GM systems via the myGMC app unless in specific regions like CCPA/GDPR; data is retained indefinitely for business and legal purposes.

Consent for extensive data collection by OnStar and apps in Acadia is buried in fine print at purchase or app setup, with unclear or missing opt-out options post-Smart Driver decommissioning.

The Acadia's infotainment system is the large central touchscreen controlling navigation, audio, and vehicle settings. Owners report it frequently freezing, going completely black, or restarting rando...

The infotainment touchscreen in the 2024-2025 Acadia sometimes fails to display icons for apps and functions. This glitch leaves key features inaccessible until the system recovers or is reset.

The built-in GPS navigation system incorrectly displays the vehicle's location, such as showing Pennsylvania as Florida. Dealerships have no immediate fix for this mapping error.

The infotainment system's volume controls stop responding intermittently. Owners fix it by entering safe mode or resetting the Android system.

The digital instrument cluster behind the steering wheel randomly goes blank, hiding speed, fuel, and other critical driving information. This occurs without warning and recovers on its own.

The head-up display (HUD) projects speed and navigation info onto the windshield but stops working randomly. It requires no user intervention but disrupts the feature's reliability.

OnStar internet and services frequently fail to connect, causing issues like no GPS traffic info, unavailable Sirius stations, and inability to reach OnStar support via SOS button.

The map navigation and Heads-Up display integration require ongoing OnStar subscription after the initial free period ends, despite being advertised as 8 years free.
