What to check before buying a used 2020 Blazer
Model-year data describes the production run, not the car in front of you: two cars of this model year can differ entirely, one with every recall repaired and the other with none. The counts below are from NHTSA data collected on 2026-09-15.
- Verify the 3 recall campaigns by VINCopy the 17-character VIN from the windshield or driver-door label, not from the listing, and run it through NHTSA's free recall lookup. It shows unrepaired recalls within its coverage and does not show completed repairs, so ask the seller for dated repair paperwork. The campaigns cover the tires, the powertrain and the airbags. The newest, 21V115000, was filed in 2021.
- Test-drive for what Blazer owners report most73 of the 213 owner complaints filed with NHTSA name the electrical system: on the drive, try every light, window, lock, screen and power outlet, and watch for warning lights or a slow start. Another 72 name the powertrain: check that the transmission shifts smoothly from a stop and at highway speed, with no shudder, slipping or delay into gear. Complaints are unverified owner reports, not proven defects, but they show where to look.
- Check the title and odometer in the history reportRecall and complaint data describe the 2020 production run, not this car's past. The VIN decode here is free; the $14.99 original ClearVIN PDF lists title brands, odometer readings, accident and auction records on file for that VIN. Records vary by vehicle, and a missing record does not prove nothing happened.
- Book an independent pre-purchase inspectionHave a mechanic you choose inspect this Blazer before you buy, and ask them to look hardest at the electrical system, the powertrain and the engine.
Is the 2020 Blazer a good car to buy used?
NHTSA's records cannot rate one used 2020 Chevrolet Blazer; they can show how this model year compares with the other Blazer years in this site's 2015–2022 NHTSA collection. The 2020 has 213 owner complaints on file, the most of the four Blazer model years in this site's 2015–2022 NHTSA collection (2019–2022). The median of the Blazer years with enough complaints to compare is 158. The 2020 is the year that stands out: about 1.6× the 130 median of the other three years with enough complaints to compare. Its 3 recall campaigns are the most of any Blazer year in the 2015–2022 collection. These counts track how many were sold and how long they have been on the road, so they rank years within the Blazer, not build quality; whether one 2020 Blazer is a good buy depends on its own history and condition.
Which 2015–2022 Blazer years have the most complaints?
Among the four Blazer model years in this site's 2015–2022 NHTSA collection, the 2020 has the most owner complaints, 213. Older and better-selling years have had more time and more owners to file reports.

What this data cannot tell you
- A complete recall or repair history for one vehicle. NHTSA’s VIN lookup covers unrepaired recalls within its scope; confirm missing campaigns and completed work with the manufacturer or an authorized dealer.
- Whether a complaint is accurate. NHTSA publishes owner reports without verifying them.
- How reliable the model is overall: complaint volume tracks how many vehicles were sold as much as how they hold up.
- Anything about title brands, accident history, odometer records, or liens on an individual vehicle.

2020 Chevrolet Blazer questions
What should I check before buying a used 2020 Chevrolet Blazer?
Check the 3 NHTSA recall campaigns against the car's VIN with NHTSA's free lookup and ask for dated repair paperwork. Owners name the electrical system and the powertrain most often in 213 complaints; those are unverified reports, not proven defects, but they show what to test on the drive. Recall data says nothing about this car's past: the $14.99 original ClearVIN PDF lists title brands, odometer readings, accident and auction records on file for the VIN. Finish with an independent pre-purchase inspection.
How many recalls does the 2020 Chevrolet Blazer have?
NHTSA lists 3 safety recalls covering the 2020 Chevrolet Blazer as of 2026-09-15. Whether a specific vehicle is affected — and whether the repair was already done — depends on its VIN.
What are the most common 2020 Chevrolet Blazer problems?
Owners most often report problems with the electrical system, the powertrain and the engine to NHTSA. These are unverified owner reports and do not establish a defect, but they show where to focus an inspection.
Are Chevrolet recall repairs free?
Generally, yes for eligible vehicles, even after the warranty ends. Federal law limits the required no-charge remedy when a vehicle was first sold more than 15 years before the recall notice; a manufacturer may still cover an older vehicle voluntarily. Check the VIN with the manufacturer for the approved remedy, which may be a dealer visit or a remote software update.
Can I check recalls on a specific 2020 Chevrolet Blazer VIN?
Yes. NHTSA's free VIN lookup reports unrepaired recalls within its coverage. It excludes completed repairs and can omit some recent recalls, older campaigns and vehicles outside its coverage. A zero result is not a complete recall or repair history. Ask the seller or manufacturer for dated repair documentation.
