GMC Envoy XL traction light and wrench indicators illuminated on GMC Envoy XL

Some GMC Envoy XL owners report experiencing issues indicated by the illumination of the traction light and wrench indicators, which may signal problems with the traction control system and other related components. These warning lights often indicate a malfunction in the traction control system (TCS), which is crucial for maintaining vehicle control when wheels lose traction. Additionally, the wrench indicator may point to specific maintenance reminders or faults in the system that require attention. Owners have noted that the Stabilitrak system relies on a network of sensors to monitor vehicle response during emergencies, and that this system is typically active by default, resetting upon vehicle restart unless a problem is detected. It is recommended that owners seek inspection from a qualified mechanic or dealership if both indicators illuminate, to properly diagnose and resolve any underlying issues.
