Buick Encore GX Recalled For Engine Control Module Issue

GM has issued a voluntary emissions recall for certain units of the 2020 through 2023 Buick Encore GX to address an issue with the crossover’s engine control module, which may not properly clear an emissions-related code.

The problem: affected units of the Buick Encore GX may have an issue in which the engine control module (ECM) may not clear the permanent status of data trouble code (DTC) P0521 (Engine Oil Pressure Sensor Performance).

The hazards: if the ECM had previously set a DTC P0521 and the permanent status is not properly cleared, the affected Encore GX may not pass certain Emissions Inspection/Maintenance tests. The check engine light may also illuminate. This could potentially cause inconvenience to the owner of the affected vehicle.

The fix: dealers will reprogram the ECM in affected Buick Encore GX units, free of charge to vehicle owners.

Affected components: engine control module (ECM).

Affected vehicles: 

Number of affected vehicles: it’s currently unclear how many units of the Buick Encore GX may be affected by the aforementioned ECM issue. Note that some units of the 2021, 2022 and 2023 Chevy Trailblazer are also included in this voluntary emissions recall. Affected vehicles are located in the U.S. and Canada.

Owners should: wait for to be contacted by their dealer, or bring their vehicle to the dealership. For more information, owners may also reach out to Buick directly using the information included below.

    1. NO, they need to reward the staff that quickly acts to find, announce and issue the fix for their excellent product. This is a reliable and responsible auto manufacturer. Good for GM!

      1. If they picked better suppliers and had better QC on the front end most of these problems wouldn’t happen. That’s a management issue.

  3. It’s a minor recall and one that I wouldn’t even bother with since SC has no emissions testing.

  4. If you can’t clear the codes then the check engine light stays on, right?

  5. My 2020 had to replace 2 times a starter . The stop and start of system burns out starters quickly and is more cheap to turn it off and pay for the gas you supposedly save with this system crap.

    1. I’ve noticed my start/stop function completely kills my headlights at night upon the restart. Is there a way to keep it off so I don’t have to constantly keep shutting off the function?
