2023 GMC Acadia Reliability Report

Owners of the 2023 GMC Acadia report issues related to steering, with symptoms primarily involving vibrations and sensor malfunctions. One owner details a persistent vibration occurring at speeds between 45-60 mph, although a dealership visit did not identify the cause. Another owner describes a recurring issue where the temperature gauge drops to zero, accompanied by a "Steering Assist Reduced" warning, which cycles every two weeks and is linked to a temperature sensor malfunction. These complaints arise at varying mileages, with one vehicle noted at 11,000 miles. While no direct safety incidents are reported, the symptoms could potentially affect driving stability and steering control.

Owners of the 2023 GMC Acadia report several engine-related issues. Multiple complaints mention excessive oil and water consumption, with one owner stating the need to add a quart of oil every couple of weeks. Engine stalling before a complete stop and hard or delayed shifting are also reported, alongside instances of the digital speedometer and other dashboard lights failing temporarily. One incident involves a crash where the vehicle lunged forward unexpectedly while parked, resulting in injuries and airbag deployment, occurring at approximately 20,000 miles. These reports highlight potential safety implications, including loss of control and unexpected vehicle movement.

Owners of the 2023 GMC Acadia report two distinct issues related to visibility and wipers. One complaint describes an unexpected sunroof explosion while driving on the highway, resulting in shattered glass entering the vehicle, which nearly caused a collision. Another issue involves the smell of windshield washer fluid entering the cabin when the washer is used, particularly noticeable when the HVAC system is active. This has been confirmed by multiple GMC representatives and documented through several examinations. These issues are noted without specific mileage references, but they present potential safety risks, including distraction or potential exposure to harmful vapors.

Owners report issues with air bag deployment in the 2023 GMC Acadia, particularly in situations involving crashes. Complaints frequently mention that during incidents, such as unintended acceleration leading to a crash into a tree and a collision with a deer at highway speeds, the air bags fail to deploy. These issues are noted at mileage as low as 5,665. Safety implications include crashes with significant vehicle damage and at least one reported injury. Potential buyers should be aware that air bag non-deployment is a recurring theme in these reports.
