2015 GMC SIERRA DENALI Complaints

POWER BRAKE VACUUM PUMP ISSUE. LOST BRAKES WHILE DRIVING IN STOP AND GO CITY TRAFFIC. HAD TO HAVE TRUCK TOWED, WAS UNSAFE TO DRIVE DUE TO NO BRAKES.

INTERIOR DASH LIGHTS GOES OUT AND A FEW MINUTES LATER THE ENGINE CUTS OFF WHILE I'M TRYING TO PARK. EACH TIME WHILE I WAS BACKING INTO MY PARKING SPACE. AFTER SITTING FOR ABOUT 30 SECONDS THE LIGHTS DASH BOARD LIGHTS COME BACK ON, THEN I RESTART THE TRUCK. SOMETIMES WHILE DRIVING THE DASH BOARD LIGHT BLINK OF AND ON.

VEHICLE STARTED SHOWING "SERVICE LANE DEPARTURE SYSTEM, SERVICE PARK ASSIST, SERVICE TRAILER BRAKE SYSTEM" ALARMS WHILE DRIVING. UPON TAKING IT TO THE DEALER FOR SERVICE IT WAS FOUND TO HAVE BROKEN WIRING FOR HAPTIC MOTOR FOR DRIVERS SEAT. NOT ONLY DID THIS CAUSE A POSSIBLE SAFETY ISSUE WITH THE LANE DEPARTURE SYSTEM AND TRAILER BRAKE SYSTEM NOT WORKING CORRECTLY, BUT IT ALSO CAUSED A POSSIBLE FIRE CONCERN DUE TO BROKEN WIRING.

STARTING THE VEHICLE I'M PUTTING THE TRUCK IN REVERSE, THE TRUCK LUNGES BACKWARDS. ALSO A VIOLENT JERK OF THE VEHICLE HAPPENS. THIS HAPPENS A MAJORITY OF THE TIME. PUTTING THE VEHICLE INTO GEAR TO DRIVE I HAVE A VIOLENT JERK AND A LOUD NOISE. THE TRUCK DOES NOT LUNGE FORWARD WHEN PLACING THE TRUCK INTO DRIVE. THIS HAPPENS A COUPLE OF TIMES A DAY. THIS IS NOT AN ISOLATED INCIDENT.

HARD BRAKE PEDAL. AT LOW SPEED THE BRAKE PEDAL GETS REALLY HARD AND MAKES IT HARD TO STOP THE TRUCK. PEDAL HAS TO GET PUSHED REALLY HARD TO BARELY STOP FROM HITTING OTHER VEHICLES. ONGOING ISSUE.

MY GMC 2015 DIESEL DURIMAX TRUCK HAD THE ENGINE LIGHT TURN ON AND SAID EMISSION NEEDS SERVICED. IT PROCEEDED TO CUT MY TRAVELING SPEED FROM 75 MPH TO 65 MPH TO 55 MPH. I MADE IT TO DENVER COLORADO BARELY WITHOUT THE TRUCK FALLING TO 4 MPH. I WENT YESTERDAY TO HAVE IT SERVICED. THEY SAID THAT THEY FIXED IT STILL UNDER POWERTRAIN WARRANTY. I DROVE AWAY TO GO BACK TO TEXAS 700 MILES OF HIGHWAY HOME. I DROVE AND THE EXACT SAME PROBLEM HAPPENED AGAIN. I'M WAS ON A HIGHWAY AT THIS POINT WITH HEAVY HIGHSPEED TRAFFIC IN THE MIDDLE OF NOWHERE WHERE THE SPEED LIMIT IS 75 MPH. MY TRUCK SPEED WAS REDUCED BY THE EMISSION SYSTEM AGAIN FROM 75 MPH TO 65 MPH TO 55 MPH. I WAS ALMOST HIT BY A BIG RIG TRUCK WITH MY WIFE IN THE CAR. SOMETIME LATER WERE ALMOST SIDE SWIPED TWICE, AND THEN IT STARTED RAINING AND THE SUN STARTED TO SET, AND MATTERS WENT FROM DANGEROUS TO NEAR DEADLY. WE TRIED TO TURN THE TRUCK AROUND TO GET BACK TO DENVER AND ALMOST WERE HIT AGAIN BECAUSE WITH THE GMC SPEED REDUCTION I COULD NOT ACCELERATE AWAY FROM THE HIGH SPEED CARS COMING AT US. GMC SHUTDOWNS THE CAR SPEED PURPOSELY TO AVOID SOME TINY AMOUNT OF NOX, AND PUT PEOPLE AT RISK OF BEING KILLED ON A HIGHWAY IN RAINY NIGHTIME WEATHER. WE FINALLY MADE IT BACK TO DENVER JUST 19 MILES BEFORE THE TRUCK SPEED WOULD HAVE BEEN REDUCED TO 4 MPH. WE WOULD HAVE TO BEEN ON THAT 75 MPH HIGHWAY RIDING IN THE RIGHT SIDE OF THE SLOW LANE AT 4 MPH !!!!! AT NIGHT IN THE RAIN WITH HIGH SPEED 18 WHEELERS GOING BY AT 75 TO 85 MPH. THE GOVERNMENT AND GMC ARE INSANE TO HAVE DESIGNED THIS, I AM BRINGING IT TOMORROW TO GET TRY TO GET IT FIXED AGAIN BUT THE ORDEAL I WENT THRU IS STILL SCARY AS HELL, AND WORRIED ABOUT IT GETTING FIXED. WE COULD BE KILLED DUE TO THIS. I AM AN ENGINEER DEALING WITH PUBLIC SAFETY, AND I AM IN SHOCK CONCERNING GMC'S AND THE GOVERNMENT OVER STEP IN THIS DESIGN.
