Market analysis
How much does a used Buick Envision engine computer cost?
Asking prices for a used Buick Envision engine computer are unusually spread out: the top listing asks more than ten times what the cheapest does, so which unit you pick matters more than the median. Condition matters: grade-A units (lowest mileage, best condition) carry roughly a 25% premium over grade-C stock, with grade-A medians at $125.
Fitment variant moves the price more than most buyers expect. The most affordable variant we track, Electronic Control Module, ID 12668437, lists at a $99 median, while Electronic Control Module, ID 12655021 commands $100, a 1% gap inside the same part category. Confirm which variant your VIN requires before comparing quotes.
Model year matters too: 2020 units carry the lowest median at $82, while 2022 tops the table at $186. Parts from 2017–2021 are interchangeable, so if the 2020 fits your vehicle, it offers the best value across 4 compatible years.
Against comparable vehicles, the Buick Envision sits 2% below the Honda Accord ($112), 1% below the Honda Civic ($111), and 13% below the Hyundai Elantra ($126) for the same part. The “similar vehicles” cards below open each comparison guide.
Buying a used engine computer: what to check
- Match hardware and service numbers: Ensure hardware revision codes and circuit board part numbers match exactly, as pinouts change mid-model year.
- Inspect multi-pin connector headers: Check header pins for bending, green copper oxidation, or burnt circuit board traces inside the wiring sockets.
- Verify immobilizer programming requirements: Plan for anti-theft security relearn procedures or ECU re-flashing before the replacement computer will start the engine.
- Confirm donor transmission and emissions spec: Ensure the donor vehicle used the same transmission type and regional emissions package to prevent fault codes.
- Check aluminum casing seals: Inspect housing screws and perimeter rubber gaskets for white oxidation or breaks that indicate past water intrusion.
