Chevrolet Traverse doors locking and unlocking with engine racing and shutting off on Chevrolet Traverse

Some Chevrolet Traverse owners report experiencing unexpected door locking and unlocking issues, which may be linked to several factors. A common cause is a dead coin battery inside the key fob, leading to erratic door locking behavior. Additionally, faulty door lock actuators can prevent doors from opening from the inside, as these small motors are crucial for electronically locking and unlocking the doors. Some owners have also noted problems with the Body Control Module (BCM), which can disrupt signals to the power door actuators, resulting in improper locking or unlocking. Furthermore, those with a Passive Locking system may find that it automatically locks the vehicle shortly after the engine is turned off, potentially misidentifying the key fob's presence and causing unexpected locking. To address these issues, owners are advised to check the key fob battery, inspect the door lock actuators, have the BCM evaluated, and understand the Passive Locking system's operation. If these measures do not resolve the problem, consulting a certified mechanic or dealership for a thorough diagnosis is recommended.
