2019 Chevrolet Blazer Reliability Score & Common Problems

Owners report that the 2019 Chevrolet Blazer frequently experiences issues related to the steering system, with many complaints mentioning a "Steering Assist Reduced" warning. This issue often coincides with a P0128 error code, a stuck temperature gauge, and the engine cooling fan running continuously. Symptoms also include malfunctioning air conditioning and intermittent power steering failure, which may lead to a loss of vehicle control. These problems are typically reported at mileage ranges around 40,000 to 60,000 miles. The complaints highlight potential safety risks, such as reduced steering control and unexpected braking, which could lead to accidents.

Owners report frequent issues with the thermostat in the 2019 Chevrolet Blazer, with several complaints indicating failure around 30,000 to 60,000 miles. Symptoms commonly include a malfunctioning temperature gauge and air conditioning, as well as warnings about steering assist. Some owners also mention engine light activation. Additionally, a few complaints highlight problems with the starter and flex plate, linked to the auto start-stop feature, resulting in vehicle stalling without prior warning indicators. There are safety implications noted, such as vehicles losing power or overheating, which can lead to breakdowns on the road. These patterns suggest potential reliability concerns for buyers considering this model.

Owners of the 2019 Chevrolet Blazer frequently report issues with the service brakes, including brake pedal hardening and failure to stop the vehicle, which in two cases resulted in crashes. One such incident led to an injury when the vehicle failed to stop at a 3-way stop, causing it to enter a ditch. Complaints also mention the brake system engaging unexpectedly, notably on dirt roads and after stopping at traffic lights. Some owners describe symptoms of brake-related electronic malfunctions, such as the vehicle displaying "shift to park" errors and messages about reduced engine power. These issues appear to occur without warning and are not consistently tied to specific mileage ranges, though at least one owner experienced repeated issues after a prior repair. Potential buyers should be aware of these reported brake system problems and the associated safety implications.

Owners of the 2019 Chevrolet Blazer report issues with the airbag system, with complaints highlighting two primary problems. One owner describes a severe accident where the airbags did not deploy despite significant impact, indicating a potential failure in the airbag activation. Another owner experiences frequent airbag alert warnings, particularly in extreme temperatures, which persist despite multiple service attempts. Additionally, there is a report of airbags deploying unexpectedly during a swerve on icy roads without a collision, leading to substantial repair costs and parts availability issues. These complaints suggest potential safety implications, including non-deployment in crashes and unnecessary deployment, which could be of concern to used car buyers.

Owners of the 2019 Chevrolet Blazer report issues with vehicle speed control, particularly involving unexpected engine revving and adaptive cruise control malfunctions. One complaint describes the vehicle jerking forward and engine RPMs increasing while braking, despite no pressure on the gas pedal, with no warning lights or diagnostic findings from the dealership. Another owner reports adaptive cruise control intermittently becoming unavailable and shutting off, despite software updates and component replacements. These issues began after a few months of ownership and persist despite dealer interventions. No crashes or loss of control are reported, but the unpredictability of these systems could affect driving confidence.

Owners of the 2019 Chevrolet Blazer report issues with premature tire wear and air loss. One owner describes Michelin tires wearing down to 5/32" tread at under 14,000 miles, leading to concerns about safety and the need for replacement. Another owner experiences slow air loss in a Continental tire, associated with a low tire pressure warning light, at approximately 35,000 miles. These complaints suggest potential safety implications, such as reduced traction and handling, particularly in adverse weather conditions. Buyers considering this vehicle should be aware of these tire-related issues and inspect tire condition and tread depth prior to purchase.
