Is Your Buick Encore Experiencing Frustrating Engine Problems?
As a mechanic with over two decades of diagnostic experience, I’ve seen it all. A 2019 Encore that suddenly won’t start, idles rough, stalls unexpectedly, or has a persistent Check Engine Light that no one can solve. These aren’t just annoyances; they’re signs that the very brain of your engineโthe Engine Control Module (ECM)โmay be failing. When the ECM malfunctions, it can throw the entire system into chaos, affecting fuel economy, transmission shifting, and overall drivability.
The Smart, Reliable Solution: A VIN-Programmed OEM ECM
Forget the exorbitant costs and scheduling headaches of a dealership visit. We offer a genuine, road-tested OEM Engine Control Module with service number 12669908, sourced from a salvaged vehicle. This isn’t just a part in a box; it’s a complete solution. Before we ship it, our technicians will program the module using your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures the ECM has the latest GM software calibrations precisely matched to your Encore’s factory settings.
Real-World Diagnostic Story: “A customer’s 2018 Equinoxโwhich uses this exact same ECMโcame into my shop last month. It had intermittent stalling and a flurry of communication error codes. Another shop had already replaced two sensors to no avail. After checking the main power and ground circuits to the module, I suspected the ECM itself. A quick swap with a known-good unit confirmed my diagnosis. The original ECM had an internal failure that only appeared when it warmed up. This pre-programmed module would have been the perfect, cost-effective fix for him.”

Important Post-Installation Steps: Your Responsibility
Modern vehicles have sophisticated anti-theft systems. After installing this 2019 Encore ECM, a ‘Vehicle Anti-Theft System Relearn’ (VATS relearn) procedure may be required if the engine cranks but does not start. This is a standard security measure, not a part defect. This procedure requires a professional scan tool or access to GM’s TIS2WEB system and is the responsibility of the installer.
Additionally, other vehicle-specific setups like a Crankshaft Variation Relearn or injector flow rate programming may be necessary to achieve optimal performance. Please ensure your mechanic is equipped to perform these final integration steps.
Simple Installation Guide
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes for the system capacitors to discharge.
- Locate the ECM: On most compatible models, the ECM is found in the engine compartment, often near the battery or on the driver’s side fender well.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old ECM. Inspect the pins on the harness side for any corrosion or damage and clean them if necessary.
- Remove Old Module: Unbolt the old ECM from its mounting bracket.
- Install New Module: Mount your new, pre-programmed ECM and securely reconnect the wiring harnesses. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Relearns: Attempt to start the vehicle. If it does not start, proceed with the required security relearn procedure as mentioned above.
This part is a confirmed fit for a wide range of GM vehicles. Please verify that your original module carries the service number 12669908 to ensure compatibility.
