Is Your 2016 GM Vehicle Running Rough?
If you’re experiencing frustrating and unpredictable issues with your 2016 Chevrolet Cruze, Malibu, or Cadillac CT6, the root cause might be a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it starts to fail, it can create a cascade of problems that are often difficult to diagnose, leading to costly repairs and significant downtime. Don’t let a faulty computer keep you off the road. This is a direct-fit, professionally programmed replacement ECM, part number 12672502, designed to restore your vehicle’s performance and reliability.
We had a 2016 Malibu come into the shop with a complaint that was baffling the owner. The car would intermittently stall at red lights, the check engine light would flash on and off randomly, and the transmission seemed to shift harshly one day and perfectly fine the next. The owner had already replaced the spark plugs and a coil pack with no improvement. After hooking up our professional scan tool, we saw a host of communication error codes pointing towards the ECM. Instead of a clear-cut sensor failure, the data logs showed the computer was simply making erratic decisions. We installed a VIN-programmed ECM, and it was like a new car. All the ghost-like issues vanished instantly. It’s a classic case of how a failing central computer can mimic a dozen other problems.
Common Symptoms of a Failing ECM
A failing engine computer can manifest in numerous ways. If your vehicle is exhibiting any of the following symptoms, a faulty ECM could be the culprit. This replacement part is the solution for restoring your vehicle’s proper function.
- ✔ Check Engine Light: The check engine light is illuminated or flashes intermittently, often with codes that are inconsistent or point to multiple unrelated sensors.
- ✔ Engine Stalling or Misfiring: Your vehicle may stall unexpectedly while driving or at idle. You might also notice rough idling, hesitation during acceleration, or engine misfires.
- ✔ No-Start Condition: The engine cranks but refuses to start. This can happen if the ECM is not properly controlling the fuel and spark delivery.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s gas mileage can be a sign that the ECM is not managing the engine’s fuel mixture efficiently.
- ✔ Transmission Issues: On modern vehicles, the ECM works with the Transmission Control Module (TCM). A faulty ECM can cause harsh shifting, delayed engagement, or the transmission getting stuck in one gear.
- ✔ Intermittent Electrical Problems: Since the ECM communicates with nearly every module in the car, its failure can cause bizarre, unrelated electrical gremlins to appear.
The Plug-and-Play Solution: Our Programmed 2016 Cruze ECM
Replacing an ECM isn’t as simple as swapping the part. Modern vehicle computers are coded specifically to the Vehicle Identification Number (VIN) of the car they are installed in. This is a security measure known as the anti-theft system. Simply installing a used or new, unprogrammed module will result in a no-start condition. Typically, this requires a trip to the dealership for expensive and time-consuming programming.
We eliminate that step entirely. When you purchase this 2016 Cruze ECM (part number 12672502), you provide us with your vehicle’s VIN. Our technicians will then flash the module with the latest, most up-to-date software directly from GM for your specific vehicle. This ensures perfect compatibility with your engine, transmission, and all factory options. The unit arrives at your door ready for installation—no additional programming or dealer visits required. This saves you time, money, and the headache of towing your vehicle to a service center.

Frequently Asked Questions
Is this part ready to install when I receive it?
Yes! This ECM is fully programmed to the VIN you provide during checkout. It is a true plug-and-play solution. Simply disconnect your battery, swap the module, reconnect the battery, and you’re ready to go. No dealership visit is necessary.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find your VIN on your vehicle’s registration, insurance card, or on a placard on the driver’s side dashboard visible through the windshield.
What if I have aftermarket modifications?
This ECM is programmed with the original factory GM software for your specific VIN. It is not designed to accommodate aftermarket performance modifications. It will restore the vehicle to its original factory operating parameters.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a failing ECM, this part will resolve the issue. However, it’s crucial to ensure your vehicle has been properly diagnosed, as the check engine light can be triggered by many other faulty components like sensors or wiring.
Do I need to perform a security relearn procedure?
In most cases, because we pre-program the unit to your VIN, no additional security relearn is needed. The vehicle should recognize the new ECM and start without issue. Instructions for a simple key relearn procedure, if needed, are available upon request.
