A Technician’s Notebook: The Intermittent Stall Case
A customer brought in their 2015 Encore that would stall unpredictably at traffic lights. They’d been to two other shops that replaced the battery and alternator, but the problem persisted. No codes were stored, making it a diagnostic nightmare. In my experience, intermittent electronic failures, especially when heat-related, often point to the ECM. The internal circuits and solder joints can degrade from thousands of heat cycles. We swapped in a pre-programmed ECM, and after a 30-minute test drive, the issue was gone for good. It’s a reminder that for these symptoms, the 2013-2016 Encore Engine Module is often the root cause.
Is Your Vehicle Showing These Symptoms?
- âś” Check Engine Light is on with codes like P0601, P0606, or U-series communication codes.
- âś” The engine cranks but refuses to start.
- âś” Unexplained drops in fuel economy.
- âś” The vehicle stalls unexpectedly, especially when warm.
- âś” Hesitation or stumbling during acceleration.
- âś” Automatic transmission shifts erratically or harshly.
- âś” Other warning lights (like traction control) illuminate without reason.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electronic work.
- âś” Locate the ECM: On the Buick Encore, the ECM is typically found in the engine bay, often mounted to the side of the engine or firewall. It’s a metal box with several large electrical connectors.
- âś” Disconnect and Remove: Carefully unplug the wiring harness connectors. They have locking tabs that need to be released. Once disconnected, unbolt the old module from its mounting bracket.
- âś” Install the New Module: Bolt your new, pre-programmed 2013-2016 Encore Engine Module into place. Securely plug in all wiring harness connectors, ensuring they click and lock.
- âś” Final Steps: Reconnect the negative battery terminal. The vehicle may need to complete a security relearn procedure, which often involves turning the key to the ‘ON’ position for 10-15 minutes before starting. Consult your owner’s manual for specific instructions.
