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.

Speedometer and rms needles do not function.

SERVICE AIRBAG light came on last week. Took vehicle to dealership to fix. Parts are discontinued so airbag cannot be fixed per Ferman Chevrolet dealership. Also told me that airbag will not work if in an accident.

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!

WHILE DRIVING THE WHEEL JERKED TO LEFT. I CROSSING LAKE BRIDGE..I WONDER WHAT WAS THAT. THEN IT WAS LIKE I HAD 2 FLAT TIRES ON FRONT.. I SLOWED DOWN. JUST TO GET ACROSS BRIDGE TO PULL OVER.. IT STARTED DRIVING NORMAL. SO IT WASN'T TIRES. THEN STARTED AGAIN. SO GOT IT BACK HOME. THINKING IT TI RODS SWAY BAR, ETC. GOT ALL NEW FRONT END PARTS. NOW STEERING WHEEL JUSTS SPINS. NOW TOLD RACK AND PINION. MY CAR BEEN SITTING FOR 2 MONTHS TRYING FIGURE OUT WHAT COULD BE ISSUE.
