My transmission is leaking fluid and has trouble going in reverse. This model Has had two recalls in 2020 and 2021 with the one from 2020 Was specifically for missing parts on the transmission causing leaks. My car is under the mileage for the transmission to even be a problem as stated by multiple mechanics. If there was a recall why wasn’t I informed before the transmission began to leak. The is serviced regularly by dealership where car was purchased. My safety is important to me but I guess not to CHEVROLET BECAUSE I MEVER WAS TOLD ABOUT A POSSIBLE ISSUE WITH THE TRANSMISSION. SO I HOPE YALL TAKE NOTICE AND DO THE RIGHT THING
Thermostat has gone bad. Talked to Chevy and they said it is a known issue.
Warning message flashes "put car in park" after putting it in park and pushing the stop button. It flashes for a few minutes, beeps the horn alert, and you can't lock it . It was diagnosed at a Chevy dealership as needing new switch and jumper harness at almost $800.
The well known Shift to Park issue where the park sensor is off and my vehicle won’t shut off without being able to register it’s in park. Auto garage quoted $600+ to replace the entire shift assembly. There’s a service bulletin out for this issue and the specific 2019 blazer but no recall
1.The vehicle does not recognize it's in park periodically and will not shut off 2. Thermostat housing and thermostat failure 3. Tint covered chrome on exterior of body peeling off Only had the car 3 weeks Currently at dealership repairing thermostat out of pocket

We have had it in to the dealer and they said the its the thermostat or the temp sensor. From wha…

I keep getting this message that pops up, "Steering Assist reduced Drive with Care". At the same time this happens the temp gauge stays on cold, the ac quits working, the engine fan is on high, and most of the time I get code PO128. We have had it in to the dealer and they said the its the thermostat or the temp sensor. From what I am reading it could be a factory issue with the EMI issue from sensitive ECT circuitry. This has been an ongoing issue for us for over a year.
I am currently receiving a shift to park message displayed while my vehicle has been put in park and after I turn the vehicle off. While the message is displayed, the doors will not lock and a bell will not stop dinging, notifying me of the error. I have to start the vehicle, shift into gear, shift into park, and turn off seve…

I am currently receiving a shift to park message displayed while my vehicle has been put in park and after I turn the vehicle off. While the message is displayed, the doors will not lock and a bell will not stop dinging, notifying me of the error. I have to start the vehicle, shift into gear, shift into park, and turn off several times before the error disappears. I have an appointment to have the dealer look at it this week.
