AI Safety Analysis for the 2019 Chevrolet Blazer

The 2019 Chevrolet Blazer presents a mixed safety picture. While it boasts excellent crash test performance with a 5-star overall NHTSA safety rating, including 5 stars for frontal and side impacts, and 4 stars for rollover, its complaint data reveals several recurring issues that impact daily drivability and potentially safety. With 174 total complaints, 4 crashes, 2 injuries, and no fires or deaths reported, the vehicle's structural integrity in a crash appears robust. However, a significant number of complaints point to persistent electrical and powertrain problems. The most common complaint patterns revolve around the 'Shift to Park' error and thermostat failures. The 'Shift to Park' issue, frequently reported under 'UNKNOWN OR OTHER' and 'ELECTRICAL SYSTEM' components, prevents the vehicle from recognizing it's in park, leading to an inability to turn off the car, lock doors, and persistent alarms. Thermostat failures, often linked to 'ENGINE' and 'ELECTRICAL SYSTEM' complaints, result in check engine lights, reduced driver assist features, non-functional AC, and potential engine overheating. These issues, while not directly causing crashes in the reported data, can be highly inconvenient and, in the case of engine problems, could lead to more severe mechanical failures if unaddressed. Recall history for the 2019 Blazer includes two significant campaigns. One recall addresses 'TIRES' for potential sidewall breaks or belt edge separation, which could lead to sudden air loss. The second recall, under 'POWER TRAIN:AUTOMATIC TRANSMISSION', concerns missing bolts on the start-stop accumulator endcap, potentially causing transmission oil leaks and a loss of propulsion. This transmission recall directly aligns with some 'POWER TRAIN' complaints and highlights a known manufacturing defect that could increase crash risk. Despite the high crash test ratings, the recurring operational issues and recall history suggest that owners may face reliability challenges and potential safety concerns related to propulsion loss or tire failure.

Reliability Score

The 2019 Chevrolet Blazer receives a reliability score of 65 out of 100 based on analysis of NHTSA complaint data, recall history, crash reports, and safety ratings. This indicates average reliability — some notable concerns exist that prospective buyers should be aware of.

Known Issues for the 2019 Chevrolet Blazer

The following issues have been identified from NHTSA complaint data and owner reports for the 2019 Chevrolet Blazer:

IssueSeverityFrequencyTypical Mileage
Shift To Park Error
Vehicle fails to recognize it's in park, preventing shut-off, locking, and causing persistent alarms. Often requires wiggling shifter or multiple attempts.		 Medium Common variable miles
Thermostat Failure
Thermostat gets stuck open, leading to check engine light (P0128), 'driver assist reduced' messages, non-functional AC, and potential engine overheating.		 Medium Common 30000-60000 miles
Transmission Oil Leak/Loss Of Propulsion
Missing bolts on start-stop accumulator endcap can cause transmission fluid leaks and lead to a sudden loss of propulsion while driving (subject of a recall).		 High Occasional variable miles
Tire Sidewall/Belt Separation
Over-cured tires may develop sidewall breaks or belt edge separation, leading to sudden air loss (subject of a recall).		 High Rare variable miles
Electrical Components Not Turning Off
Electrical components remain active after parking, often linked to the 'Shift to Park' issue, draining the battery.		 Medium Occasional variable miles

Frequently Asked Questions About the 2019 Chevrolet Blazer

Is the 2019 Chevrolet Blazer safe?

Based on NHTSA data, the 2019 Chevrolet Blazer received excellent crash test ratings, including a 5-star overall safety rating. However, it has 174 complaints, 4 crashes, and 2 injuries reported, along with two recalls for tire and transmission issues. While it performs well in crashes, recurring electrical and engine problems, like the 'Shift to Park' error and thermostat failures, are common.

What are common problems with the 2019 Chevrolet Blazer?

The most reported issues for the 2019 Chevrolet Blazer are the 'Shift to Park' error (often categorized under 'UNKNOWN OR OTHER' and 'ELECTRICAL SYSTEM'), and thermostat failures (under 'ENGINE' and 'ELECTRICAL SYSTEM'). Other significant complaints relate to the 'POWER TRAIN', including transmission issues and potential loss of propulsion, which is also covered by a recall.

Are there any recalls for the 2019 Chevrolet Blazer?

Yes, the 2019 Chevrolet Blazer has two recalls. One recall (NHTSA ID: 20V792000) addresses over-cured tires that may develop sidewall breaks or belt edge separation. The second recall (NHTSA ID: 19V764000) is for missing bolts on the start-stop accumulator endcap, which can lead to transmission oil leaks and a loss of propulsion.

What is the 'Shift to Park' issue?

The 'Shift to Park' issue is a common problem where the 2019 Chevrolet Blazer fails to detect that the gear shifter has been moved into the 'Park' position, even when it has. This prevents the vehicle from fully shutting off, locking the doors, and often triggers persistent warning messages and alarms. It's a significant inconvenience and a frequently reported complaint.

How serious are the thermostat problems?

Thermostat problems in the 2019 Chevrolet Blazer are moderately serious. They often trigger a check engine light (P0128 code), cause the engine temperature gauge to stay on 'cold', disable the AC, and can lead to 'driver assist reduced' warnings. If left unaddressed, a stuck-open thermostat can prevent the engine from reaching optimal operating temperature, potentially affecting fuel efficiency and, in severe cases, could lead to engine damage if it gets stuck closed and causes overheating.

Buyer Advice

Our recommendation: While the 2019 Chevrolet Blazer offers strong crash protection, be aware of common 'Shift to Park' and thermostat issues, and ensure all recalls for tires and transmission are addressed before purchase.
