I have found multiple times that the Instrument Panel (IPC) display and the center Infotainment displays have gone dark while driving. This has put me in unsafe driving situations because I am unable to monitor my speed and other important information displayed on the dashboard, or to control critical safety controls such as headlights, and other ADAS safety controls. Several software updates have been installed by the dealership, but the problem has persisted, suggesting a hardware issue with the radio unit. The manufacture insist it is a software problem and that they are working on a solution. Declining to replace the radio under warranty, additionally, they want me to wait until a new update is released, and in the meantime, my bumper-to-bumper warranty is about to expire. I have found that the radio unit is the main control module for both displays, multiple ADAS controls, and Headlights, and it should be recalled, with the manufacturer extending the warranty or including the radio as a safety feature under the extended powertrain warranty.

My complaint is with the standard HID headlights in the 2019 Blazer and the very poor mounting system. The headlights are mounted TOO LOW to be effective in lighting the roadway, particularly where no shoulder stripping is on the roadway. Too, at unlighted intersections the lighting so poor that safe left or right turns cannot be accomplished. The HID lights themselves are a poor design in that they do not offer any useable peripheral lighting to add vision to the road shoulders. Due to the low mounting, the HID do not adequately shine light onto the road surface. Rather the available light shines across the surface and not down on it had the lights been mounted at the top of the fenders as most lights are mounted and designed. This has been an ongoing issue with the vehicle since purchasing the car new in November of 2018.

Headlights flash or stay on either low or hi beam,hatch opens itself, awd poping, noise in dash, shifting into awd by itself, transmission not shifting correctly . There is no pattern and it throws no codes. Major electric problems. The keyless entry pad didn't work the day I purchased my car. Had a new one installed 3 programs and now all this started.

While driving at night the high beams go out and the interior light will not turn off when the doors are closed or the switch turned off.

The low beam headlights went out simultaneously while I was driving at night. I proceeded to the auto parts store, bought new bulbs and changed them out but they still did not come on. All other lights are working including the high beams. I see there are recalls for the same problem listed online for 2007 tb's but when I checked with gm/buick I was informed that my VIN was not listed in the recall due to it not being on the production line at a certain plant. Yet with further research there are numerous complaints from other tb owners with the same issue as the recalled VIN's which should show this is a parts issue. I was referred to the dealership by gm/buick a diagnostic of which I will have to pay for because my vehicle was on a different production line for a part that clearly appears to be defective!
