Is Your 2010-2011 Impala Running Rough, Stalling, or Throwing Baffling Codes?
If you’re dealing with persistent engine problems in your Chevrolet Impala, you know the frustration. You might be experiencing a rough idle, poor fuel mileage, hesitation, or even a no-start condition. Often, the root cause isn’t a faulty sensor or a bad fuel pump—it’s the vehicle’s brain, the Powertrain Control Module (PCM). As the central command for your engine and transmission, when the PCM starts to fail, it can create a cascade of confusing and hard-to-diagnose issues.

This isn’t just another part; it’s the definitive solution. We offer a genuine replacement PCM (Part Number 12597125) that arrives at your doorstep fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We install the latest, most stable software updates from GM, ensuring your engine operates at peak efficiency and reliability. This corrects many factory-level bugs and drivability issues you might not even know you have.

- âś” Unexplained Check Engine Light (CEL) that won’t clear.
- âś” Engine stalling or cutting out while driving.
- âś” Harsh or erratic automatic transmission shifting.
- âś” A noticeable drop in fuel economy.
- âś” Vehicle won’t start, but the battery and starter are good.
- âś” Communication error codes (U-codes) with your scan tool.
A Real-World Scenario from My Shop
A customer’s 2011 Impala came in last month with a no-start condition. They had already replaced the crankshaft position sensor and the fuel pump based on some forum advice, with no luck. After connecting my scan tool, I found no communication with the PCM. Before condemning the module, I checked the basics: power and ground connections at the PCM connectors, located inside the air cleaner housing on this model. The connections were solid. This confirmed the internal circuitry of the original PCM had failed—a common issue I’ve seen in over a hundred of these GM vehicles. Installing one of our pre-programmed modules had the car running perfectly in under 30 minutes, saving the customer from an expensive and unnecessary dealership tow and diagnostic fee.
