The radio screen is constantly going black or glitching, the music will silence, the back up camera will stop working. Carplay does not connect often, also glitches in and out when driving. There is little to no air or heat coming from the floor panel when feet option is pressed for climate. In order to feel heat or A/C have to be on face option.

"Shortage in radio" according to Chevrolet's diagnostic. Caused black screen, no back up camera, no beeping when in reverse and coming close to another object, no sound when blinkers or hazard lights are on, no radio, no power to front charger, no ability to use front auxiliary cable. Initially a loud buzzing noise which could not be controlled by the volume dial. Problems began on or around October 7, 2022. Purchase was made September 2020. Vehicle is available for inspection upon request. Problem can be reproduced/is constant. Problem was reproduced by dealer. Vehicle was inspected by dealer. There were no other warning lamps.

Shortly after purchasing my trailblazer in 2020 I noticed a glitch in the speakers where it would make a crackling noise (mainly when the car is off). it hasn’t been consistent when it happens, but since observing the issue I notice the issue happens most often when I close the trunk (by pressing the button on the trunk door.) no warning lights shows when this happens. Although this doesn’t seem to be a harmful safety issue, anything electrical can result to something more serious. I plan to bring this issue up at my next oil change at the dealership.

Started having issues where all the electronics on the car go blank/dead. So far when this has happened it has not caused the car to be inoperable but in the meantime I have found that the car is leaking (seriously leaking) under the entire drivers seat was soaked. I noticed a while back that it smelled like mildew in the car, I had it cleaned and put a damp rid pouch in there, that basically absorbed in 2 days, but never could find the water. This week I found the water...under the drivers seat. This car has been leaking for 2 years! Last night, I get in the car and plug in my phone to charge and get a message of LIQUID DETECTED Charging is not available because liquid has been detected in the lightning connector. Disconnect to allow the connector to dry. At the same time the phone was plugged in everything started to crackle and squeal through the radio and then no radio at all. There is no way all these components are not damaged. Meanwhile I have take it to a dealer for them to do a "water test", I have zero confidence that this water test will yield any positive results and I am without a vehicle . So I am trying to get this info out anywhere I can to see if other people had similar issues and what can be done. It can not be safe to drive a car that the electronics have water damage.
