How to Reset the Maintenance Wrench Light on Buick Encore?
2 Answers
Turn off the ignition switch to cut off the power supply to the car. Press and hold the buttons on the dashboard simultaneously, keeping both trip reset buttons pressed for more than 5 seconds. Turn the key to the second position (accessory mode) without starting the engine, and wait until all dashboard lights illuminate. This process typically takes about 10 seconds. Wait for the wrench light to go off. Once it's off, release both trip reset buttons. Turn off the ignition switch and then turn it back on to complete the maintenance reset.
I've noticed the maintenance wrench light is quite common on the Buick Encore, and I've personally experienced it several times. To reset it, the method is straightforward: First, park the car and turn off the engine, ensuring it's completely shut down. Then, press and hold the TRIP button on the left side of the steering wheel without releasing it. Next, turn the key to the ACC or ON position (where the dashboard lights up but the engine doesn't start), and keep holding the button for about 5 to 10 seconds until the wrench icon disappears on its own. Note that this should only be done after the maintenance is completed; otherwise, it's just masking the problem. I recommend regularly checking the odometer and performing maintenance every 5,000 kilometers or so to extend the engine's lifespan. Always perform this operation after parking, never while driving—safety first.
