Is Your Chevy Sonic Giving You Headaches?
Is your 2012 Chevy Sonic running rough, stalling unexpectedly, or showing a persistent check engine light?

We provide the definitive solution: a professionally programmed ECM, matched specifically to your vehicle’s VIN, designed to restore your Sonic’s performance and your confidence on the road.
Common Symptoms & Your Solution
A failing ECM can disrupt your vehicle’s entire operating system, leading to a wide range of problems that can be difficult to diagnose. If you’re experiencing any of the following, a faulty module is the likely culprit:
