2021 Buick Encore Gx recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Brakes
What's wrong, in plain English: Anything that slows the car down. Treat brake recalls as urgent. Sensor connection contamination in the electronic brake boost system may cause an interruption of communication between the sensor and the brake boost system.
What could happen: If communication with the sensor is interrupted, the electronic brake boost assist could be lost. Extra pedal force will be required to slow and stop the vehicle, increasing the risk of a crash.
The fix: GM will notify owners, and dealers will replace the electronic brake boost module, free of charge. The recall began December 9, 2020. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-333-4223, or Buick customer service at 1-800-521-7300. GM's number for this recal…
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2021 ENCORE GX.
- Book a repair at any authorized Buick dealer. Quote NHTSA campaign 20V588000 (manufacturer code A202307260).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-630-2438.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
