2020 Buick Encore GX

A component is listed below if NHTSA records a vehicle recall campaign, a manufacturer warranty extension or service campaign, or at least 10 distinct consumer complaints.

Recall campaigns

NHTSA lists these campaigns as covering certain 2020 Buick Encore GX vehicles. One campaign can list several components, so these do not sum to the 2 vehicle campaigns on record.

  • Service Brakes1 campaign21 distinct complaints
  • Equipment1 campaignno complaint count above OAV’s minimum of 10

Manufacturer campaigns

The manufacturer filed these with NHTSA as warranty extensions or service campaigns.

  • Electrical SystemWarranty extensionmost recently Aug 26, 2024

    A warranty extension does not establish that this vehicle is covered, or that coverage is unexpired. Coverage depends on the program, the VIN, and its date of first sale — confirm with a franchised dealer.

  • EngineWarranty extensionmost recently Sep 1, 2026

    A warranty extension does not establish that this vehicle is covered, or that coverage is unexpired. Coverage depends on the program, the VIN, and its date of first sale — confirm with a franchised dealer.

  • Exterior LightingWarranty extensionmost recently May 3, 2024

    A warranty extension does not establish that this vehicle is covered, or that coverage is unexpired. Coverage depends on the program, the VIN, and its date of first sale — confirm with a franchised dealer.

Federal law requires the manufacturer to remedy a safety recall at no cost to the owner — by repair, replacement or refund — for vehicles not more than 15 years old on the date the defect was determined.

Parts are sometimes on back-order and some remedies are interim, so a dealer may not be able to complete the work immediately. A specific vehicle’s current recall status is available through NHTSA’s VIN recall lookup.

OAV lists only communications filed as warranty extensions or service campaigns. Buick filed 631 other service communications for this model year; those are not listed.

These federal records are not an input to OAV’s price verdict.

These records describe the 2020 model-year, not any individual vehicle, and are not an inspection. One complaint can be recorded against more than one component, so counts do not sum to the model-year total. Service records for any component listed here are worth requesting from the seller. Showing 5 of 7 components with records above OAV’s publication floor — see all 7 for this model-year.

Complaints are unverified consumer reports submitted to NHTSA. Mileage is self-reported and frequently rounded. Complaint records as of 2026-09-18. Recall records as of 2026-09-18. Manufacturer communications as of 2026-09-18.

About This 2020 Buick Encore GX

Listing updated: Sep 19, 2026

Listed by an independent dealer in Graham, NC · On lot for 51 days · VIN verifiable at NHTSA

This used 2020 Buick Encore GX Preferred is listed at $16,350 by d & d truck and auto inc in Graham, NC 27253. It has 64,009 miles on the odometer (dealer-reported, not independently verified by OAV). The exterior color is Gray. It features a 4WD drivetrain and Automatic transmission.

OAV's independent, evidence-backed Price-to-Market analysis rates this vehicle as a Great Deal — priced below the supported comparable range. Based on 17 comparable listings matched to this vehicle, the estimated market range is $17,575 to $18,641. These comparisons match year, make, and model, using trim where the data supports it. OAV does not adjust comparable prices for mileage — every price shown is the real advertised price. On used vehicles, mileage can still cause OAV to withhold a verdict — very high or unreliable mileage, or a lower price better explained by higher-than-typical mileage than by a genuine market discount — rather than call it a deal it can't support.

This vehicle has been on the lot for 51 days.

Analysis powered by OAV's patented inventory standardization technology (U.S. Patent No. 12,236,477). Verdict methodology ptm-verdict-v1 · snapshot Sep 19, 2026. The patented comparable band is the input; ptm-verdict-v1 is the versioned OAV rule set that turns it into this verdict.

Market context

This listing is part of OAV's broader Graham, NC suvs market analysis. OAV compares vehicles by local and regional price-to-market ranges and comparable count; days-on-lot and demand signals are shown separately, not as verdict inputs.

How this deal is rated

OAV compares this 2020 Buick Encore GX against similar vehicles currently available for sale — same make, model, and year range, using trim where the data supports it. OAV does not adjust comparable prices for mileage; on used vehicles it withholds a verdict when mileage would distort the comparison — very high or unreliable mileage, or a lower price better explained by higher-than-typical mileage than by a genuine market discount — rather than overstate a deal. Based on where this listing falls in that comparable set, it is rated:

  • Great Deal — priced below the comparable-range floor by a meaningful margin (OAV's minimum-gap rule); a listing below the floor by less than that margin is Fair Price.
  • Fair Price — priced within the expected range for comparable vehicles.
  • Overpriced — priced above the typical range for comparable vehicles.

Listings show OAV's PTM-derived deal quality and live market context. OAV-claimed dealers manage their listing profile and route buyer inquiries directly. Paid OAV partners can surface additional verification signals, but commercial participation never changes a listing's Price-to-Market verdict, eligibility, ranking, or confidence.
