Is the 2019 Chevrolet Blazer reliable?

The 2019 Chevrolet Blazer has 186 owner complaints on file with NHTSA, below the median of 281 for 2019 SUVs on this site. Of the 7 Blazer model years since 2019, it has the 2nd most complaints. Complaint counts rise with sales as well as faults, so read what owners report below before deciding.

At a glance

Next to the 2020
At 23 complaints for each year on the road, the 2019 runs below the 2020 (31). That's the only adjacent model year with enough complaints to set beside it.
Top problem
Shift to park warning leads with 44 of the 186 complaints (24%), ahead of stalling at 25. A quarter of the 12 owners who gave a mileage for shift to park warning saw it by about 21,000 miles, and half by about 37,000.
Crash, fire and injury reports
Only 4 of the 186 complaints (2%) report a crash, a fire or an injury, well under the 6% typical of vehicles on this site. Counted separately (one report can carry more than one), 4 reports mention a crash and 2 people were hurt.
Recalls behind the top problems
Shift to park warning has a recall on the same system (20V-668). Stalling and overheating have none. A recall on the same system doesn't always cover the failure owners describe, so compare its summary with the complaints.
When owners filed
Complaints are still climbing. 2025 brought 55, the most of any year so far. So far in 2026, 20 more have come in.

        How this compares

        2019 Chevrolet Blazer186
        Median 2019 model here (93 vehicles)237
        Median 2019 SUV here (50)281

        186 complaints is 1.3 times fewer than the median 2019 model on this site and 1.5 times fewer than the median 2019 SUV. Among the 3 Blazer model years here it ranks 2nd for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.

        Service bulletins for the 2019 Chevrolet Blazer

        Chevrolet filed 849 bulletins and other notices with NHTSA that list the 2019 Chevrolet Blazer. 57 of them deal with a problem owners have reported on this car. Newest first.

        Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

Owners may contact GMC customer service at 1-888-988-7267, Buick customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.
