As much as I love this 2019 Blazer RS, there are issues.
My engine warning light keeps coming on intermittently. A call to On-Star while driving to diagnose says it the fuel system not in optimum economy or something like that. Dealer can't seem to catch it either. No fix so far.
My adaptive cruise will just cut out and shut off. Error says Service driver assist System after the Adaptive Cruise Fails and shuts off. Dealer can't locate problem.
My rear tailgate will not open most of the time with the foot sensor. Sometimes I get lucky but if it's not 100% who's going to ever use it?
My blind spot warning lights on my mirrors stopped working some time ago.
The infotainment system keeps turning my iPhone volume down to almost zero. Very annoying. On-Star says they are aware of the issue but no fix in sight.
The official optional Chevrolet mats for the hatchback compartment came with no way to secure the large floor mat so that it doesn't slide around if you have the aluminum track for the luggage stand.

Love the car overall. 308 HP is plenty for a daily driver. Last highway trip, I got 9.4 l / 100 km or 25 MPG (US) or 30 MPG (CAN) at highway speeds of 123 km/hr or 76 MPH.

 

I have a 2021. And I have had air conditioning ,front brake, radio,back brake and now my car just started running hot and told me to pull over. I'm over and done with making a car payment and I don't have a car to drive. So you are not alone with issues

 

The side mirror issue was my fault.

With all the diagnostics and constant monitoring through On-Star it baffles me why known issues that they have collected the data on are not being resolved.
