Is Your Car Running Rough? Get a Simple, Reliable Fix.
Is your Chevrolet Cruze, Sonic, or other GM vehicle suddenly stalling, running poorly, or simply refusing to start? A faulty Engine Control Module (ECM) is often the culprit, acting as a frustrating roadblock in your daily life. It’s the brain of your engine, and when it fails, it can cause a cascade of problems from poor fuel economy to a car that won’t run at all. This is your direct, reliable solution to restore your vehicle’s performance and get you back on the road with confidence.

Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM comes fully programmed to the VIN you provide. The complex flashing and software updates are all handled by our technicians before shipment, making the installation process as simple as possible.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
Will this definitely fit my vehicle?
This ECM fits a wide variety of GM vehicles. Please carefully review the detailed fitment list on this page. Matching one of the listed part numbers (like 12668866, 12643636, etc.) to your old unit is the best way to confirm compatibility for your Programmed 2012-2016 Cruze ECM or other model.
What is a security or key relearn procedure?
On some GM vehicles, a simple security relearn procedure may be required after installation to sync the new ECM with your vehicle’s anti-theft system and keys. This procedure typically takes 10-30 minutes and does not require special tools. We can provide instructions for this common process.
