Within 3 months of owning the vehicle I started to hear a crackling sound coming from the passenger speaker in the door. At first it was loud and I thought someone hit me. It did it several times and then stopped. It has happened about a dozen times since I have owned the vehicle. When I took it in for my oil change I told them and they could not replicate it so they didn't know what it was and didn't see anything. It actually just happened again yesterday so when I take it in again I will tell them about this. We thought maybe it was only when it rained but that is not the case, it just happens and I can't think of anything that is consistent when it does. It comes out loud and scares me every time. I just want this fixed, I have only owned my car for 1 year now and like everything but this.

I WAS DRIVING MY BRAND NEW 2021 TRAILBLAZER (ONLY 160 MILES) AND STEPPED ON THE BRAKE TO STOP AT THE END OF A STREET. SUDDENLY, I GOT ALERTS THAT MY BRAKE SYSTEM HAD FAILED AND RIGHT AFTER THAT, ANOTHER ONE, SAYING THAT THE POWER STEERING NEEDED TO BE SERVICED. AT THAT POINT, IT REQUIRED MUCH MORE PRESSURE ON THE BRAKE TO STOP, AND THE BRAKES DIDN'T SEEM VERY RESPONSIVE. LATER I SHUT OFF THE ENGINE, AND WHEN I STARTED IT AGAIN, THE CHECK ENGINE LIGHT WAS STILL ON, BUT I THINK THE BRAKES WERE WORKING AGAIN. I'M NOT SURE BECAUSE I DIDN'T WANT TO DRIVE IT, JUST IN CASE.

TWO TIMES I HAVE HEARD A LOUD POP NOISE COMING THROUGH MY STEREO SPEAKERS. I NOTICED IT WHEN APPLYING THE BRAKES. I WENT ON A TRAILBLAZER FORUM AND A FEW OTHERS HAD REPORTED THE SAME THING. I HEARD THE POP TODAY WHEN I WAS PULLING INTO A PARKING SPOT AND APPLYING THE BRAKES.
