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.
GMC filed 840 other service communications for this model year, nearly all routine repair instructions. OAV lists only warranty extensions and service campaigns; routine bulletins are not listed.
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.

About This 2020 GMC Terrain
Listing updated: Sep 18, 2026Listed by an independent dealer in Hillside, IL · On lot for 3 days · VIN verifiable at NHTSA
This used 2020 GMC Terrain Denali is listed at $26,998 by carmax hillside (eisenhower expy) in Hillside, IL 60162. It has 29,068 miles on the odometer (dealer-reported, not independently verified by OAV). The exterior color is White. It features a 4WD drivetrain with a 2.0L I4 engine and Automatic transmission.
OAV's independent, evidence-backed Price-to-Market analysis rates this vehicle as Overpriced — priced above the supported comparable range. Based on 17 comparable listings matched to this vehicle, the estimated market range is $18,412 to $25,263. 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 3 days.
Analysis powered by OAV's patented inventory standardization technology (U.S. Patent No. 12,236,477). Verdict methodology ptm-verdict-v1 · snapshot Sep 18, 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 Hillside, IL 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 GMC Terrain 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.
