2015 CHEVROLET SILVERADO 1500 Complaints

TL* THE CONTACT OWNS A 2015 CHEVROLET SILVERADO 1500. WHILE DRIVING APPROXIMATELY 75 MPH, THE REAR OF THE VEHICLE WAS UNSTABLE, SWERVED, BOUNCED, AND VIBRATED. THE VEHICLE WAS TAKEN TO THE DEALER WHO INSTALLED NEW SHOCKS, BUT THE FAILURE CONTINUED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE LEAF SPRINGS WERE FAULTY. NO FURTHER INFORMATION WAS AVAILABLE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 3,000.

THE VEHICLE WAS A TOTAL LOSS. LOSS CONTROL WHILE AVOIDING A DEER. SLID INTO DITCH. HIT A DRIVEWAY ENTRANCE. WAS AIRBORNE APPROX. 15 YARDS. NOSE DIVED INTO THE GROUND AND WENT BACK ACROSS THE DITCH INTO A FIELD, TURNED LEFT AND WENT INTO A WOODED AREA OF PINES. LEFT FRONT FENDER MADE CONTACT WITH A PINE ( ABOUT EIGHT INCHES THICK ) PARTIALLY UP ROOTING AND CONTINUED ON TO WEDGE BETWEEN TWO PINES. AIR BAGS FAILED TO DEPLOY AND THE SEAT BELT TIGHTEN UP SO TIGHT THAT I HAD TO USE A FAIRLY LARGE SCREW DRIVE, THAT I HAD IN THE CENTER CONSOLE, TO BEAT THE RELEASE IN ORDER TO UNLOCK THE SEAT BELT. WITH THE VEHICLE GETTING AIRBORNE AND NOSE DIVING INTO THE GROUND AND THE IMPACT OF THE LEFT FRONT FENDER INTO THE TREE, THE AIR BAGS SHOULD HAVE DEPLOYED. THE VEHICLE WAS TRAVELING SOUTH EAST ON A HIGHWAY IT WAS APPROX. 9:30 PM.

VEHICLE WAS IN FOUR WHEN DRIVE LOW STOPPED AND GOT OUT TO OPEN A GATE HEARD A LOU POP LOOKED BACK IT WAS ROLLING BACKWARDS WENT ABOUT 200 FEET WITH A TRAILER HOOKED TO IT THE TRAILER FLIPPED AROUND HIT THE SIDE OF THE TRUCK MADE ANOTHER LOUD SOUND AND IT STOPPED. WE ARE BEING TOLD NOTHING IS WRONG WITH IT. ANOTHER TIME HAD IT IN LOW FOUR WHEN DRIVE AND IT KEPT ROLLING IN PARK. THE VEHICLE WAS PARKED. AND WHEN WE GOT TO IT THE GEAR SHIFT WAS STILL IN PARK.

I AM CONCERNED ABOUT THE EXCESSIVE SHAKING/VIBRATION IN THIS 2015 CHEVY SILVERADO AND, THUS FAR, GM CUSTOMER SERVICE AND THE DEALERSHIP HAVE NO RESOLUTION IN SIGHT. THE PROBLEM HAS BEEN OCCURING AT HIGHWAY SPEEDS (MOST NOTABLE ABOVE 73 MPH) SINCE THE TRUCK WAS PURCHASED AUG 2015. AS THEY CAN'T IDENTIFY THE CAUSE OF THE PROBLEM, I CAN'T BE SURE THE ORIGIN IS OR IS NOT A SAFETY-REATED CONCERN. THE DEALERSHIP HAS BALANCED, RE-BALANCED, ROTATED, AND ROAD PRESSURE TESTED TIRES TO NO AVAIL. EVEN TRIED A NEW SET OF TIRES OFF OF A 2016 MODEL TO NO AVAIL. AS THIS MATTER CONTINUES AND DOESN'T APPEAR TO BE TIRE-RELATED, I'M WORRIED THAT THE ISSUE MAY BE IN THE SUSPENSION AND WILL, AT SOME POINT, CAUSE OR CREATE A CATASTROPHIC FAILURE.

CHECK TRAILER WIRING WARNING - WHILE DRIVING DOWN THE ROAD AT DIFFERENT SPEEDS, WEATHER, SMOOTH VERSUS ROUGH ROADS, WHILE PULLING TWO DIFFERENT TRAILERS, THE TRUCK INDICATES TO CHECK THE WIRING AND 1 SECOND LATER IT INDICATED THE TRAILER IS CONNECTED. IT MAY HAPPEN SEVERAL TIMES IN A MILE AND THEN NOT OCCUR FOR 50 MILES. ONE TIME THERE WAS A MESSAGE TO CHECK THE BRAKE CONTROLLER. THIS HAPPENS EACH TIME I HOOK A TRAILER UP TO THE TRUCK. TRUCK IS AT THE DEALER AND THEY ARE SAYING THERE IS NOTHING WRONG WITH THE TRUCK. 6 MONTHS AGO WHEN I PULLED THE SAME TRAILERS WITH MY 2012 CHEVY PICKUP, I DID NOT HAVE THIS CONCERN. ONLY STARTED WITH THE NEW TRUCK. IS A CONCERN WHEN THE TRAILER BRAKES DO NOT WORK DURING THIS TIME. THIS COULD BE A SERIOUS PROBLEM WHEN I TOW MY TRAVEL TRAILER AGAIN.

SERVICE# PIP4112Q 2015 CHEVROLET SILVERADO. 10,000 MILES. DURING ACCELERATION AT LOW SPEEDS WHILE TURNING OR CHANGING LANES VEHICLE HESITATES AND SAG. RESULT OF TORQUE MANAGEMENT. SAFETY CONCERN WITH TURNING INTO TRAFFIC. MANUFACTURER STATES WORKING AS DESIGNED AND FAILING TO RESPOND WITH REPAIR/RECALL.

QUOTED GAS MILEAGE FOR V6 MODEL WAS 25/19, I AM ONLY GETTING 19 MILES PER GALLON. I CHOSE THE V6 DUE TO BETTER GAS MILAGE BUT I'M GETTING LESS MILAGE THAN THE V8 MODEL.

I BOUGHT THE CAR THREE DAYS EARLIER. THE VEHICLE HAS 4800 MILES ON IT. IT IS A CERTIFIED USED TRUCK. I WAS DRIVING ON A CURVY ROAD ON THE SIDE OF A SMALL MOUNTAIN. WHILE DRIVING, I NOTICED THE STEERING GETTING A LITTLE PLAY IN IT, NOT MUCH EVER SO SLIGHT. WHEN I GOT TO THE 90 DEGREE LEFT TURN, ONTO ANOTHER ROAD, I FOUND I HAD LOST THE ABILITY TO TURN THE VEHICLE. THE TRUCK STARTED TOWARD THE TREES. I HIT THE BRAKES AND GAVE IT ALL I HAD, MUSCLE WISE, IN ORDER TO MAKE THE TURN. I PULLED OVER AND REGAINED MY COM-POSHER. I DID NOTICE THERE WAS A MESSAGE ON THE INSTRUMENT PANEL INDICATING A PROBLEM WITH THE STEERING AND TO BE CAREFUL DRIVING, I DID NOT NOTICE THAT MESSAGE BEFORE THE INCIDENT. I THEN PROCEEDED TO DRIVE TO TO THE DEALERSHIP VERY SLOWLY WITH THE FLASHERS ON. I ONLY HAD TO MAKE FIVE TURNS AND EIGHT MILES TO GO TO THE DEALERSHIP. THE STEERING WAS MAKING ALL KINDS OF NOISES AND JERKY MOTIONS. THERE WAS NO INJURIES OR DAMAGE DONE TO THE VEHICLE DURING THIS INCIDENT. I JUST WONDER WHAT WOULD HAVE HAPPEN IF MY WIFE OR ONE OF MY DAUGHTERS WERE DRIVING.

THE TRUCK HAS A CONSTANT VIBRATION AT HIGHWAY SPEEDS. TWO DIFFERENT DEALERS HAVE VERIFIED THE PROBLEM, GM FIELD ENGINEERS VERIFIED THERE IS AN ISSUE, AND THE ENGINEER RECOMMENDED THE DEALER CHANGE REAR END PARTS, STILL NO FIX. TWO DIFFERENT DEALERS FELT ROADFORCE BALANCING THE TIRES WOULD HELP; IT HAS NOT. THE TRUCK ALSO MAKES A CHIRPING NOISE WHEN TRANSITIONING FROM 4 CYLINDERS BACK TO 8 CYLINDERS.

PLEASE SEE ATTACHED DOCUMENTS PERTAINING TO VIBRATION ISSUES, EMERGENCY BRAKE CABLE BEING CUT AND U-JOINTS OOZING GREASE. ALSO HAVE NUMEROUS VIDEOS ON THE VIBRATION ISSUES LIKE MANY OTHERS.
