Common problems reported by 2023 Buick Encore Gx owners, with recommended fixes and estimated repair costs.

1

CVT/9-Speed Transmission Jerking and Rough Shifting

Depending on the engine option, the Encore GX uses either a CVT or 9-speed automatic, both of which have reported issues. Owners experience jerking motions while driving, rough gear engagement, delayed shifting, and transmission slipping. Transmission fluid leaks have also been reported, which can lead to low fluid levels and accelerate internal wear.

Solution

Transmission fluid level check and top-off. Transmission fluid service with GM-approved fluid. TCM software update for shift calibration improvement. For persistent issues, torque converter or complete transmission replacement. Address fluid leaks promptly from seals and lines.

Est. Cost: $200 (fluid service) - $4,500 (transmission replacement)
2

Emergency Jack Fracture Risk

The factory emergency jack can fracture during use if not positioned exactly as directed in the owner's manual. A fractured jack can cause the vehicle to collapse onto the ground, potentially injuring anyone underneath or near the vehicle during a tire change.

Solution

NHTSA recall for 2020-2022 Buick Encore GX. Dealers replace the defective emergency jack with an updated design, free of charge. Owners should avoid using the factory jack until the recall is completed and should carry an alternative lifting device as a precaution.

Est. Cost: $0 (recall repair)
3

1.2L/1.3L Turbo Engine High-Pressure Fuel Pump Failure

The high-pressure fuel pump can fail, causing unexpected stalling, hard starting, loss of power during acceleration, and eventually a no-start condition. The failure can occur without warning, potentially leaving owners stranded. Some owners report hearing a whining noise from the fuel system prior to failure.

Solution

Replace the high-pressure fuel pump. Inspect the fuel lines for proper pressure. Dealers may also need to replace the fuel pressure sensor. If the engine was damaged from running lean due to insufficient fuel pressure, additional engine repairs may be necessary.

Est. Cost: $500 - $1,200
4

Electrical System Malfunctions

Owners report various electrical issues including flickering headlights, battery drain, infotainment screen freezing, and random warning lights. The stop/start system may also malfunction, failing to restart the engine or restarting with a harsh jolt. Some owners experience the vehicle entering an unresponsive state requiring a full power cycle.

Solution

12V battery replacement with correct AGM specification battery. BCM software update for parasitic drain and stop/start issues. Inspect and tighten ground connections. Replace the alternator if voltage regulation is out of specification.

Est. Cost: $200 - $1,000
5

Turbo Engine Oil Consumption

The small-displacement turbo engines (1.2L and 1.3L) used in the Encore GX can consume oil between changes at rates that concern owners. The turbocharger seals and PCV system are common sources of oil loss. Low oil levels can cause turbocharger damage and accelerated engine wear.

Solution

Check oil level frequently between changes. Inspect the PCV valve and crankcase ventilation system for proper operation. Inspect the turbocharger for oil leaks at the inlet and drain. If oil consumption exceeds GM's threshold, piston ring or turbo seal replacement may be warranted under warranty.

Est. Cost: $0 (warranty) - $2,500 (turbo seal or piston ring replacement)
