Is Your 2017 Enclave Running Rough? The ECM Might Be the Culprit.
The Engine Control Module (ECM), often called the engine computer, is the central command center for your 2017 Buick Enclave’s engine. It meticulously manages everything from fuel injection and ignition timing to emissions controls and transmission shifting. When this critical component begins to fail, it can cause a wide range of frustrating and often confusing symptoms that can leave you stranded. If you’re dealing with persistent check engine lights, poor performance, or intermittent stalling, you’ve come to the right place for a reliable, plug-and-play solution.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Noticeable decrease in fuel economy.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Rough or erratic idling.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Transmission shifting issues or getting stuck in a gear.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Unexplained loss of power and poor overall performance.

Frequently Asked Questions
Do I need to get this ECM programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready for installation.
Where is the ECM located on my 2017 Buick Enclave?
On the 2017 Enclave, the ECM is typically located behind the engine’s cooling fan shroud, making it accessible from the front of the engine bay.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, this part will resolve the issue. It’s crucial to have a proper diagnosis to confirm the ECM is the point of failure, as other sensors or components can cause similar symptoms.
Is any special procedure needed after installation?
In many GM vehicles, a security relearn procedure (also known as a Passlock or anti-theft relearn) may be required after installation. This procedure can typically be done without special tools and involves a series of key cycles. Instructions are widely available online or in service manuals.
How do I provide my VIN?
You can add your 17-digit VIN to the notes section during checkout or reply to your order confirmation email with the information. We cannot ship your part until we receive the VIN.
