Considering its affiliation to Chevrolet, Buick, and its vehicles have always been associated with dependability. The 2021 Buick Encore GX is an embodiment of a similar ideology. Despite being sold over 70,000 times, 2021 MY of the SUV has had only 8 complaints and 2 recalls registered to its name. While most of its complaints are mechanical, the reliability statistics put the Encore GX in an idealistic position and promise an almost trouble-free ownership experience, compared to the likes of the Hyundai Kona, the Honda HR-V, and the Mazda CX-3. Let’s have a closer look at the Buick Encore GX problems and the remedies that the brand has provided the buyers to deal with recurring issues.

2021 Buick Encore User Complaints and Problems

Mechanical Complaints

  • Stalling of the engine: The Buick Encore GX engine problems are not a recurring concern for the vehicle. Yet, one buyer of the subcompact SUVhas been irked by the engine unit. The complainant reported that on four separate occasions, the engine warning light has illuminated, which has caused the engine to stall. While the vehicle was repaired each time the failure recurred, it was noted that the inadequate supply of fuel to the engine was consistently causing the problem.
  • Problem with the braking unit: Amongst the Buick Encore GX problems, underwhelming performance by the braking system tops the list. A handful of buyers have reported a delay in the braking process, which increases the halting distance. While most complaints mention the problem to be a standalone issue, one buyer experienced a failure of the power steering system, simultaneously.

Safety Complaints

  • Improper functioning of the airbag system: In a one-off case, a buyer of the 2021 Encore GX had reported the improper functioning of the airbags. It was noted that in case of a rear-end collision, the airbags have failed to deploy alongside the seat belts failing to restrain the occupant, which has resulted in injuries to the occupants.

Structural Complaints

  • Unavailability of parts: Though not an issue related to the SUV’s performance, a couple of buyers of the Encore GX have been displeased by the delay in the brand’s action to deal with the issue. In the recall about the emergency jack (referenced by NHTSA ID 21V440000), the part for replacement is not available with the dealers.
