Is Your Buick Encore Stalling, Running Rough, or Showing a Check Engine Light?
As a mechanic with over two decades of diagnostic experience, I’ve seen countless drivers frustrated by baffling engine problems. Your 2013-2016 Buick Encore might be experiencing issues like intermittent stalling at stoplights, hesitation when you accelerate, poor fuel economy, or a persistent check engine light that just won’t go away. These aren’t just annoyances; they’re signs that the brain of your engineโthe Engine Control Module (ECM)โmay be failing.
A faulty ECM can disrupt everything from fuel delivery and spark timing to transmission shifting, making your vehicle unreliable and unsafe. Often, these issues are misdiagnosed, leading to expensive and unnecessary repairs on other components. This module is the central command unit, and when it falters, the entire powertrain suffers.

Real-World Diagnostic Story
“A customer’s 2015 Encore came in last week with a P0606 code (ECM Processor Fault) and a complaint of stalling at random times, especially in traffic. They were worried about a huge repair bill. We confirmed the power and grounds to the ECM were solid, pointing to an internal failure. Instead of a costly dealer visit, we installed one of our pre-programmed modules. The entire job took less than 45 minutes in the bay. The Encore started right up, idled smoothly, and the customer drove away confident and relieved. This is the exact fix for that kind of problem.”
Easy Installation: A DIY-Friendly Repair
You can get your Buick back to peak condition without specialized tools. Follow these simple steps to replace your 2013-2016 Encore Engine Control Module. Remember to always prioritize safety.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure the system is fully discharged.
- Locate the ECM: On the Buick Encore, the ECM is typically found in the engine bay, often mounted near the battery or firewall.
- Disconnect Connectors: Carefully release the locking tabs on the wiring harness connectors and pull them straight out from the module. Never force them. Inspect the pins for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket. Note the orientation for when you install the new one.
- Install the New ECM: Mount your new, pre-programmed module in place and tighten the bolts.
- Reconnect Everything: Firmly plug the wiring harnesses back into the new ECM until they click into place. Reconnect the negative battery terminal.
- Final Step: Start the engine. The vehicle may need to run for a few minutes to complete its internal relearn processes. Your check engine light should be off, and the drivability issues resolved.
