Low tire presher lights stay on even when the tire presher is ok. Also I want to say the anti sliding feature says it is not working as well. I could be wrong about this feature but there si a button on the gear shift that controls this option. The button will not turn it on and off.

I've had the brakes replaced because I thought they were an issue I was having with my ABS. But my car will randomly lock its brakes as I'm driving, no matter what speed. I'm scared to drive it. It also almost loses all power after breaking but then speeds up on its own making it almost impossible to slow down or brake.
My doors have had water seeping in them the whole time and I’ve replaced my speakers multiple times.

AROUND 2019, I NOTICED THAT EACH TIME I STARTED MY TRAILBLAZER, THE "SERVICE AIR BAG" LIGHT WILL FLASH FOR A MINUTE, THEN GOES OFF, THEN COMES RIGHT BACK ON AND STAYS ON. THERE HAVE BEEN SOME DAYS WHEN IT ONLY FLASHED THEN WENT OFF, BUT AFTER ABOUT A FEW MONTHS, THE "SERVICE AIR BAG" LIGHT REMAINS ON. HAVE TAKING IT TO THE CHEVROLET DEALERSHIP TO GET A DIAGNOSIS. THE LIGHT REMAINS ON AT ALL TIMES. AFRAID THAT IF I WAS INVOLVED IN AN ACCIDENT, THE AIR BAG WILL NOT DEPLOY!
THE FIRST THING TO GO WRONG WAS THE POWER WINDOWS DON'T WORK PROPERLY IN THE WINTER, NOW THE AIR CONDITIONER ONLY BLOWS COLD AIR INTERMITTENTLY, AND THE MOST RECENT PROBLEM IS THE HEADLIGHTS WON'T WORK AT ALL, I CALLED THE LOCAL SERVICE CENTER AND THEY SAID THAT THE ELECTRICAL RECALLS WERE VIN SPECIFIC, EVEN THO I HAD THE CORRECT MAKE MODEL AND YEAR MY VIN DID NOT QUALIFY FOR THE RECALL! I'M VERY UPSET THAT THEY CAN BE VIN SPECIFIC BUT I'M HAVING ALL THE ISSUES ON THE RECALLS!! I CAN NO LONGER DRIVE MY VEHICLE IF IT IS RAINING, FOGGY, OR DARK BECAUSE I HAVE NO HEADLIGHTS!!! I ALSO LOST CONTROL OF MY CAR IN THE RAIN AND THINK IT HAS TO DO WITH THE STABILITRAK, THE LIGHT HAS BEEN ON FOR A WHILE, LUCKILY I STOPPED MY CAR BEFORE I CRASHED INTO ANYTHING
