Is Your Buick Encore Running Rough? The Solution is Here.
If you’re dealing with a frustrating check engine light, unpredictable stalling, poor fuel economy, or a no-start condition in your 2013-2016 Buick Encore, the Engine Control Module (ECM) is a highly likely culprit. As the central computer for your vehicle, a failing ECM can create a cascade of baffling problems that can be difficult to diagnose. I’ve seen it countless times in my shop: a vehicle comes in with what seems like a dozen different issues, but a quick scan points directly to an internal ECM fault.
Don’t let a faulty computer keep your reliable Encore off the road. This is a direct-fit, fully programmed Engine Control Module that restores your vehicle’s performance and reliability without the exorbitant cost and hassle of a dealership visit.
A Story From The Shop
“A customer’s 2015 Encore came in last week with these exact symptoms: it would randomly lose power on the highway and the check engine light would flash, but then it would drive fine for a few days. They had already replaced spark plugs and a coil pack with no success. After hooking up my professional scanner, I saw communication errors with the ECM that weren’t setting a specific ‘bad ECM’ code. This is a classic sign of internal failure. We installed one of our pre-programmed modules, and the customer called back a week later to say the Encore was driving better than it had in years. This is a fix that works.”

Simple Installation Process
Replacing your ECM is a straightforward job that most DIYers can handle in under an hour. No complex wiring or special tools are needed.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Locate the ECM: On the Buick Encore, the ECM is typically located in the engine bay, mounted near the battery or firewall. It’s a silver box with several large electrical connectors.
- Disconnect and Remove: Carefully unclip the wiring harness connectors. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed ECM into place. Firmly reconnect the wiring harnesses, ensuring they click securely into position.
- Reconnect and Start: Reconnect the negative battery terminal. Your vehicle is now ready to start. The security system may require a simple key relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes.
