ELECTRICAL SYSTEM
Owners of the 2019 Chevrolet Blazer frequently report issues related to the "Shift to Park" error, where the vehicle fails to recognize it is in park, preventing the car from shutting off and causing battery drain. This issue often requires the driver to repeatedly shift gears to clear the error message and fully turn off the vehicle. Complaints also mention problems with the coolant temperature sensor and thermostat, leading to error codes like P0128 and symptoms such as the temperature gauge sticking on cold, loss of air conditioning, and reduced driver assist features. These electrical issues are reported at various mileages, with some owners experiencing them as early as 35,000 miles. Safety implications include the potential for being stranded due to battery drain and concerns over engine performance and control during driving.
