2021 GMC Sierra 1500
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 2021 GMC Sierra 1500 vehicles. One campaign can list several components, so adding these counts is not a way to total the campaigns — 7 vehicle campaigns are on record for this model-year.
- Engine1 campaign348 distinct complaints
- Power Train2 campaigns136 distinct complaints
- Seat Belts2 campaignsno complaint count above OAV’s minimum of 10
- Tires2 campaignsno 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 Jan 27, 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.
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. GMC filed 1,432 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 2021 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 9 components with records above OAV’s publication floor — see all 9 for this model-year.
Complaints are unverified consumer reports submitted to NHTSA. Mileage is self-reported and frequently rounded. Complaint records as of 2026-09-28. Recall records as of 2026-09-28. Manufacturer communications as of 2026-09-28.

Listing updated: Sep 28, 2026Listed by a franchise dealer in Charlotte, NC · On lot for 9 days · VIN verifiable at NHTSA
This used 2021 GMC Sierra 1500 AT4 is listed at $39,398 by sonic automotive concierge in Charlotte, NC 28211. It has 60,558 miles on the odometer (dealer-reported, not independently verified by OAV). The exterior color is Black. It features a 4WD drivetrain with a 5.3L V8 engine and Automatic transmission.
OAV's independent, evidence-backed Price-to-Market analysis rates this vehicle as Fair Price — priced in line with the supported comparable range. Based on 55 comparable listings matched to this vehicle, the estimated market range is $24,995 to $42,087. The local comparable range around Charlotte, NC is $24,995 to $42,087; the local cohort is drawn around this dealer's market and can include listings across a state line. 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 9 days.
Analysis powered by OAV's patented inventory standardization technology (U.S. Patent No. 12,236,477). Verdict methodology ptm-verdict-v1 · snapshot Sep 28, 2026. The comparable band (patent pending) 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 Charlotte, NC trucks market analysis. OAV rates each vehicle against its comparable range and comparable count — local-first, widening the comparison set only when local inventory is too thin to support a reliable range; days-on-lot and demand signals are shown separately, not as verdict inputs.
How this deal is rated
OAV compares this 2021 GMC Sierra 1500 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 at least OAV's minimum-gap margin; a smaller gap under the floor is Fair Price.
- Fair Price — priced within the comparable range, or below the floor by less than that margin.
- Overpriced — priced above the comparable range.
- Unscored — OAV withholds a verdict when the evidence cannot support one: too few or too widely spread comparables, a price it cannot validate, a branded or salvage title, or mileage that would distort the comparison. The listing stays visible; only the rating is withheld.
Listings show OAV's Price-to-Market verdict and live market context for every dealer's inventory, whether or not the dealer has any relationship with OAV. A dealer that claims its listings can manage its profile and have buyer inquiries routed to it directly. A paying partner's own listings additionally carry an OAV Verified Partner label on the dealer contact block and a link to the dealer's own listing page. That is the complete list of what a relationship with OAV changes, and all of it concerns the dealer's identity on its own listings. Payment never changes a vehicle's verdict, its eligibility to be scored or cited, the evidence shown or withheld, or where and how prominently the listing appears on any OAV page, board, or answer. There is no paid placement, ranking, ordering, verdict badge, or featured position of any kind. OAV sells dealers insight into the evidence, never influence over it.
