When your 2015 Chevrolet Traverse's power liftgate won't open, you lose convenient access to the cargo area. The power liftgate system involves motors, sensors, latches, and control electronics—understanding these components helps identify the failure point.
Power Liftgate System Components
The Traverse power liftgate uses an electric motor with a strut assembly to raise and lower the gate. A latch mechanism with an electric release allows powered opening. Sensors detect obstacles and position. The system is controlled through the body control module and can be operated via key fob, interior button, or the button on the liftgate itself.
Common Reasons for Not Opening
The latch release actuator may have failed—you hear a click but the gate doesn't unlatch. The lift motor or struts may be weak or failed—the gate unlatches but doesn't rise. Electrical issues in wiring or the BCM prevent the system from receiving commands. The liftgate may be physically obstructed or misaligned. Safety sensors may be falsely detecting an obstruction.
Quick Checks First
Verify the vehicle is in park—the liftgate won't operate otherwise. Check that the power liftgate feature is enabled (it can be disabled in settings). Listen for any sounds when pressing the button—clicking suggests the latch is working but the motor isn't. Try all activation methods (fob, interior button, liftgate button) to determine if the issue is with a specific switch.
Latch Release Issues
If you hear no click or response from the latch when commanded, the release actuator may have failed. The latch can sometimes be manually released from inside the vehicle to verify the actuator versus latch mechanism. Electrical issues at the latch connector can also prevent release.
Repair Costs
Latch release actuator replacement costs $200-$400 including labor. Power strut/motor assembly replacement runs $400-$700 per side. Wiring repairs vary from $100-$300 depending on damage extent. If the BCM requires replacement or programming, costs reach $400-$800. Some issues may be covered under extended warranty or recalls—check with Chevrolet.
