2017 GMC SIERRA 1500 Complaints

THE TRUCK LOOSE POWER WHEN KEY IS TURNED OFF AND THEN COME BACK ON AFTER A FEW MINUTES ALSO STABILATRACK SYSTEM IS SHUTTING OFF TRUCK ONCE ON THE HIGHWAY AT 70 MPH ENGINE RUNS RUFF AND USES OIL IN LESS THAN 5000 MILES HAS USE AT LEAST 3 QUARTS THE DOD SYSTEM MAKE TRUCK RUN EXTREMELY BAD ENGINE HAS MISS IN IT ALSO IT IS BECOMING UNSAFE TO DRIVE AT TIMES AND BRAKE PEDAL IS VERY HARD TO PUSH

ASSISTED BRAKING ISSUES. WHEN GOING DOWN A HILL DOESN'T KICK IN OR SLOWING DOWN. COMES ON ONCE IN AWHILE.

THE VEHICLE FIRST STARTED VIBRATING AT HIGHWAY SPEEDS WHILE STILL UNDER WARRANTY (~15K MILES) - I TOOK IT INTO THE DEALERSHIP AND THEY SAID IT WAS JUST OUT OF ALIGNMENT - ALIGNED AND ROTATED TIRES. THIS SEEMED TO IMPROVE THINGS FOR A FEW MONTHS UNTIL THE VIBRATION WAS BACK TO THE UNTOLERABLE STATE - UPON TAKING TO ANOTHER SERVICE STATION, THEY BLAMED THE TIRES (UNEVEN WEAR) AND I PAID FOR ALL NEW TIRES - ONLY FOR THE VIBRATION TO RETURN AFTER ANOTHER FEW MONTHS. I NEXT TOOK IT A 3RD SERVICE STATION AND THEY ARE CLAIMING A BEND WHEEL THAT WONT FULLY BALANCE. AFTER RESEARCHING, I NOW SEE THAT THIS IS A VERY COMMON ISSUE WITH A FAULTY DRIVETRAIN, BUT GMC IS NOT ACKNOWLEDGING THE ISSUE?? HOW DO I BECOME PART OF A CLASS ACTION LAWSUIT IN ORDER TO GET THIS ISSUE FIXED PROPERLY?

AT LOW SPEED OR MOST OF THE TIME BACKING UP BRAKES DO NOT WORK WELL AT ALL. NEED TO PUSH VERY HARD.

VEHICLE SLAMS INTO GEAR AT INITIAL TAKE OFF AND DECELERATION FOLLOWING AN ACCELERATION WHICH CAUSES A HARD FORWARD JERK . THIS ISSUE HAS CAME CLOSE TO CAUSING ACCIDENTS ON THE HIGHWAY DURING PASSING AND DEPARTING STALLS ADJACENT OTHER VEHICLES AND/OR OBJECTS.

TRANSMISSION SHIFTS OR JERKS HARD WHEN COMING TO A STOP, SEVERE TRANSMISSION VIBRATION OCCURS WHEN TRAVELING AT SPEEDS OF 50 TO 65 MPH.

I WAS DRIVING ON I-4 TOWARDS ORLANDO AT 70MPH FOLLOWING A SAFE DISTANCE TRAFFIC WAS COMING TO STOP AND I WENT TO BRAKE AND THE BRAKES WOULDNT WORK PROPERLY AND CAUSE ME TO PULL VEHCILE TO ONE SIDE CAUSING ME TO CRASH SAW LIFE FLASH BEFORE EYES . THANKFUL TO BE ALIVE , COMES TO FIND OUT THERE WAS A RECALL ON IT

ALMOST COLLIDED WITH OTHER CARS IN PARKING LOT BECAUSE THE BRAKES WEREN'T WORKING RIGHT ALSO TRANSMISSION SHIMMIES BETWEEN 50 AND 60 MPH

WHEN STATIONARY I PUSHED IN ON THE GAS THROTTLE TO GO IT DIDN'T GO SO I PUSHED IN A LITTLE MORE AND IT ACCELERATED TO FAST THEN LIKE IT JUMPS. IT ALSO IS SHAKING AT CERTAIN SPEEDS.

THERE IS A STRONG INTERMITTENT VIBRATION IN THE STEERING COLUMN WHEN AT SPEEDS OF 35-70 MPH. IT RESEMBLE DRIVING OVER "RUMBLE STRIPS"
