Is Your Pontiac Solstice Running Rough?
There’s nothing more frustrating than a vehicle that won’t perform as it should. If your 2008, 2009, or 2010 Pontiac Solstice is experiencing baffling issues like poor fuel economy, a persistent Check Engine Light, erratic shifting, or even a no-start condition, the culprit is often the very brain of your engine: the Powertrain Control Module (PCM). This complex component manages everything from fuel injection and ignition timing to transmission function and emissions control. When it fails, it can cause a cascade of problems that are difficult to diagnose and can sideline your vehicle indefinitely.
Don’t let a faulty computer ruin your driving experience. This direct-fit replacement PCM, part number 12635901, is the definitive solution to get your Solstice back on the road, running smoothly and reliably. We take the guesswork and hassle out of the replacement process by pre-programming the module specifically for your vehicle before it ever leaves our facility.
The Heart of Your Vehicle’s Performance: The 2008-2010 Solstice PCM
The PCM is the master controller for your engine and transmission. It constantly processes data from dozens of sensors throughout your vehicle to make real-time adjustments, ensuring optimal power, efficiency, and low emissions. Over time, heat, vibration, and electrical fluctuations can cause internal components to degrade, leading to failure. A failing PCM doesn’t just reduce performance; it can lead to more significant component damage if left unaddressed.
Symptoms of a Failing PCM
If you’re experiencing any of the following issues, a faulty PCM is a likely cause. This module is your first step toward a lasting repair.
- ✔ Persistent and unexplained Check Engine Light (CEL)
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Harsh or erratic automatic transmission shifting
- ✔ A complete no-start or intermittent starting condition
- ✔ Noticeable decrease in fuel economy
- ✔ Failure to pass state emissions tests
- ✔ Communication errors with diagnostic scan tools
- ✔ Other warning lights on the dashboard appearing without cause
A True Plug-and-Play Solution
What sets our service apart is the comprehensive programming included with your purchase. Simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN) during checkout. Our technicians will then use this information to flash the module with the latest, most stable software updates directly from General Motors. This critical step ensures the PCM is perfectly matched to your Solstice’s specific configuration, including its engine, transmission, and factory options. This eliminates the need for an expensive trip to the dealership for programming.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before shipping. You just need to provide your vehicle’s VIN when you order. The module will arrive ready for installation.
Will this fix my Check Engine Light?
If the Check Engine Light is caused by a faulty PCM, this replacement will resolve the issue. It’s crucial to ensure the underlying problem isn’t a separate sensor or mechanical issue. We recommend clearing all codes after installation.
Is a security relearn procedure required?
In many GM vehicles of this era, a simple security relearn (also known as a key relearn) is necessary after installation. This procedure can typically be done yourself in about 30 minutes without special tools. We include instructions to guide you through the process.
Where do I provide my VIN?
You can add your VIN in the notes section during checkout or send it to us in a message after you complete your purchase. We cannot program and ship your module without it.
What if I have a different service number on my original part?
This module replaces multiple service numbers. As long as your original part number is listed in our compatibility list (e.g., 12597125, 12612397), this unit will function correctly once programmed to your VIN.
