Is your 2008, 2009, or 2010 Saturn Vue suffering from perplexing engine problems? A faulty Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is often the hidden culprit behind issues like a persistent check engine light, poor fuel economy, stalling, or a complete no-start condition. This isn’t just a replacement part; it’s a comprehensive solution. We provide a genuine GM engine computer, part number 12618028, that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures seamless integration and restores your vehicle’s original performance and efficiency without requiring an expensive trip to the dealership.
From the Diagnostic Bay
We once had a 2009 Saturn Vue with the 2.4L engine that was driving its owner crazy. It would randomly stall at stoplights, but the check engine light would only come on intermittently and then disappear, leaving no stored codes. The owner had replaced the spark plugs, a coil pack, and even the fuel pump with no luck. After hours of checking wiring diagrams and sensor data, we noticed the 5-volt reference signal would occasionally drop for a split second. On a hunch, we connected a spare PCM. The stalling immediately stopped. The internal circuitry of the original PCM was failing under specific thermal conditions, a classic ghost-in-the-machine problem that only a direct replacement could solve. This highlights how a failing computer can mimic a dozen other mechanical issues.
Common Symptoms of a Failing Saturn Vue PCM
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Unexplained drops in fuel mileage.
- ✔ Engine stalling, hesitating, or running rough.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle cranks but refuses to start.
- ✔ Inability for a scan tool to communicate with the module.
- ✔ Various communication error codes (U-codes).
Why Choose Our Programmed 2008-2010 Vue PCM?
The engine computer is the brain of your vehicle, managing everything from fuel injection and ignition timing to transmission shift points and emissions systems. A generic, non-programmed module from a parts store or salvage yard simply will not work. Your vehicle’s anti-theft system (Passlock/VATS) is tied directly to the PCM, and without the correct VIN programming, the engine will not start. Our process eliminates this headache. When you purchase from us, you provide your VIN, and our technicians use official GM equipment to flash the module with the latest factory software specific to your Vue. This ensures all systems communicate correctly and your vehicle operates exactly as it was designed to. This module is a direct replacement for service numbers 12597125, 12612397, 12594750, 12629019, 12635902, and 12611549, among others.
While this listing is focused on the 2008-2010 Vue PCM, this versatile module also fits a wide range of other GM vehicles, including the Chevrolet Malibu, Cobalt, HHR, Silverado 1500, Pontiac G6, G5, Solstice, and more. Please verify the part number or consult the fitment list to ensure compatibility with your specific make, model, and engine.
Frequently Asked Questions
What is the programming process?
After you place your order, you will need to send us your vehicle’s 17-digit VIN. Our technicians then use this VIN to download the latest, most up-to-date software calibration from GM and flash it directly onto the module. This ensures the computer is perfectly matched to your vehicle’s specific options and systems.
Is this part truly plug-and-play?
Yes, for most vehicles. Because we program the PCM to your VIN, it will integrate with your vehicle’s systems upon installation. In some cases, a security relearn or crank position sensor relearn may be necessary, which is a simple procedure that can be done without a scan tool. We include instructions for these potential procedures.
Where do I provide my VIN?
You can add your VIN to the notes section during checkout or send it to us in a message after you complete your purchase. We cannot ship your order until we receive the VIN, as the programming is a required step.
My old computer has a different part number. Will this work?
Most likely, yes. GM uses many different service numbers for the same hardware. This module, 12618028, supersedes and replaces several earlier part numbers, including 12597125, 12612397, and others listed in the description. As long as your vehicle is on the compatibility list, this programmed module will function correctly.
Do I need to return my old PCM?
No core charge is required for this part. You do not need to send your old, faulty computer back to us.
