Is Your Buick or Pontiac Running Rough?
If you’re experiencing frustrating issues like a persistent check engine light, poor fuel economy, stalling, or a complete no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. Your vehicle’s computer is its brain, and when it falters, the entire system suffers. Don’t let a faulty computer keep your trusted sedan off the road. This is the simple, reliable, and direct solution to restore your car’s performance and your peace of mind.
Common Symptoms & Your Solution
A failing engine computer can manifest in numerous ways, leaving you stranded and facing a confusing diagnosis. This module is the definitive solution for problems including:
- Check Engine Light with communication-related DTCs (e.g., P0601, P0606)
- Engine stalling or cutting out while driving
- Harsh or erratic shifting
- Complete failure to start
- Poor engine performance and reduced gas mileage
- Communication issues with diagnostic scan tools
By replacing your old unit with this expertly programmed 2006-2009 Buick Allure 3.8L PCM, you are installing a fresh, correctly calibrated brain into your vehicle, directly addressing the root cause of these electrical gremlins.

Expert Insight: The Importance of Correct Programming
As a technician with over two decades of experience, I’ve seen countless vehicles come in with persistent issues caused by improperly sourced or programmed control modules. A generic, non-VIN matched computer can cause more problems than it solves, from transmission damage to immobilizer lockouts. That’s why we insist on programming each 2006-2009 Buick Allure 3.8L PCM to your specific VIN. This process ensures all the unique calibrations for your car’s options and security systems are correctly loaded, making the installation process smooth and the final repair reliable. It’s the difference between a quick fix and a lasting solution.
Frequently Asked Questions
How do I provide my Vehicle Identification Number (VIN)?
After placing your order, simply send us a message with your 17-digit VIN. We cannot program and ship your module without it. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield), on your insurance card, or on the driver’s side door jamb sticker.
Do I need to do anything after installing the PCM?
Yes. While the main engine programming is complete, you will need to perform a security relearn procedure (also known as a CASE relearn or anti-theft relearn). This process syncs the new PCM with your vehicle’s existing keys and anti-theft system. It is a simple procedure that typically takes 10-30 minutes and does not require special tools. Instructions can be easily found online for your specific model.
Will this fit my Pontiac Grand Prix even though the keyword says Buick Allure?
Yes! As long as your vehicle is one of the models listed in the fitment guide (Allure, LaCrosse, Lucerne, Grand Prix) with the 3.8L engine and a matching part number, this module is the correct part for you. We use a primary model like the Buick Allure for the focus of the listing, but the 2006-2009 Buick Allure 3.8L PCM is functionally identical for all compatible vehicles.
Are these brand new modules?
These are high-quality, tested, and inspected original equipment modules that have been professionally programmed with the latest software for your vehicle. They are guaranteed to function correctly and meet or exceed original factory specifications.
What if my original part number is slightly different?
This module replaces several part numbers, including 12600930, 12616866, and 12509307. As long as your original part number is on our list, this unit will work perfectly once programmed to your VIN.
