Is Your Buick LaCrosse or GM 3.6L Vehicle Stalling or Running Poorly?
If your 2010-2011 Buick LaCrosse, Chevy Camaro, or other GM vehicle with the 3.6L V6 engine is experiencing frustrating issues like stalling, misfiring, a persistent Check Engine Light, or a complete no-start condition, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions. When it fails, it can cause a cascade of problems that are often difficult to diagnose, leading to wasted time and money on unnecessary repairs.
This replacement ECM, part number 19300015, is the definitive solution to restore your vehicle’s performance and reliability. We take the guesswork and high cost out of the equation by pre-programming the module specifically for your vehicle using your VIN. This means it arrives at your door ready for installation, loaded with the latest factory software updates from GM to ensure optimal performance and efficiency.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Engine stalling, stumbling, or misfiring, especially under load.
- ✔ Complete no-start condition where the engine cranks but won’t fire up.
- ✔ A noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Loss of communication with the ECM when using a diagnostic scan tool.
- ✔ Unexplained warning lights on the instrument cluster.
The Solution: A VIN-Programmed 2010-2011 LaCrosse ECM
Don’t let a faulty computer keep your car off the road. This module is a direct-fit replacement for a wide range of GM vehicles and is a reliable alternative to a costly dealership repair. Our process is simple: after you place your order, you provide us with your vehicle’s VIN. Our technicians then flash the module with the specific software and calibrations for your exact make, model, and options. This ensures seamless integration and proper function of all engine and vehicle systems.
Important Note for LaCrosse and Camaro Owners: For these specific models, the factory anti-theft (immobilizer) system is deeply integrated into the ECM. To provide a true plug-and-play solution, we require you to send us your original module. We will professionally extract the immobilizer data and transfer it to your new ECM. This critical step prevents a no-start condition after installation and saves you from needing specialized dealer tools for a security relearn procedure.

Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. This saves you the time, hassle, and expense of a dealership visit. For LaCrosse and Camaro models, you will need to send your old unit to us for immobilizer data transfer to make it plug-and-play.
What information do you need from me?
After you complete your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your vehicle. This is typically found on your driver’s side dashboard (visible through the windshield) or on your vehicle’s registration.
Is any other setup required after installation?
In most cases, no additional setup is needed. However, some vehicles may require a simple throttle body relearn or crankshaft position sensor variation relearn procedure, which can often be done without special tools. Instructions can typically be found online or in a service manual.
Where is the ECM located on my 2010 Buick LaCrosse?
On the 2010-2011 Buick LaCrosse with the 3.6L engine, the ECM is located in the engine compartment on the left-hand (driver’s) side. Please verify the location on your specific vehicle before ordering.
Is this a quality, tested part?
Absolutely. Each module undergoes a thorough inspection and testing process to ensure it meets or exceeds OEM specifications for performance and durability. You are receiving a reliable, fully functional component.
