The car will all of a sudden make a loud popping noise through the radio. It is enough to scare someone while they are driving and have a wreck. The brakes are very touchy to the point of almost giving you whiplash

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.

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.
