2015 Chevrolet Silverado 1500 UNKNOWN OR OTHER

THE TRANSMISSION HESITATES WHEN SHIFTING IN AUTOMATIC BUT WHEN IN MANUAL MODE IT SHIFTS FINE WITH NO ISSUES. THIS HAS BEEN A ON GOING ISSUE AND PROBLEM THE SERVICE CENTER FOR A LOCAL DEALERSHIP CAN NOT FIND THE ISSUE. BUT THERE IS SOMETHING GOING ON WITH THE TRANSMISSION.

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.

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.

WHEN DRIVING A MESSAGE ON MY INFORMATION CENTER POPS UP WHICH STATES THAT TAKING MY EYES OFF THE ROAD CAN CAUSE A ACCIDENT,ECT. THIS MAKES ME TAKE MY EYES OFF THE ROAD TO SEE IT AND AGAIN TO DELETE IT. SO THIS IS A HAZZARD. GM SAID THERE IS NOTHING IN THE OWNERS MANUAL ABOUT IT , AND ENGINEERING THINKS THAT IT HAPPENS WHEN I TOUCH A BUTTON ON THE INSTURMENT PANEL WHEN DRIVING. BUT IT HAPPENS TO APPEAR WHEN IM DRIVING ON THE HIGHWAY AND HAVE NOT TOUCHED ANY CONTROL BUTTON. , THIS IS A SERIOUS DISTRACTION. SINCE I CANNOT DUPLICATE IT BECAUSE IT HAPPENS AT RANDOM, WHEN IT DOES OCCUR AGAIN I WILL TAKE A PICTURE OF IT. THE MESSAGE WILL NOT CANCEL ON ITS OWN AND BLOCKES EVERYTHING ON THE MESSAGE CENTER UNTIL I MANUALLY SHUT IT OFF

7 PIN TRAILER CONECTOR IS MAUFACTURES AND INSTALL UPSIDE DOWN ON ALL SILVERADO TRUCKS SINCE AT LEAST 2014 AND POSSILBLY 2013. THE DOOR HOLDS THE PLUG IN; HOWERVER THE DOOR FLIPPING DOWN THE PLUG AND BOUCE AND BECOME DISCONNECTED. THIS CONNEXTION PLAYS A VITAL ROLEINLIGHTS AND BRAKING. BOTH CAN AND WILL BE LOST GM EGINEERS ARE ARWARE OF THE ISSUE HOWEVER ARE NOT FIXINGIT

COMBO 4 PIN AND 7 PIN TRAILER CONNECTION IS UPSIDE DOWN. THIS MAY RESULT IN THE LOSS OF TRAILER LIGHTS AND BRAKES. WITH CONNECTION UPSIDE DOWN THE 7 PIN DOOR WILL NOT HOLD PLUG IN TIGHTLY AND CAUSE THE BRAKE AND GROUND PINS TO POSSIBLE DISCONNECT. LOOSING BRAKES WHILE PULLING A HEAVING LOAD IS A SERIOUS SAFETY ISSUE. PLUG NEEDS TO BE INVERTED TO ENSURE THE DOOR LATCH HOLDS THE PLUG AT THE HIGH POINT AND WEIGHT OF THE CORD HOLDS THE PLUG IN TIGHTLY DEALER IS AWARE OF THE ISSUE AND GM ENGINEER IS AWARE OF THE ISSUE.. NEITHER HAS YET TO FIX. SAME DESIGN EXISTS ON 2013 AND 2014 SILVERADO'S 1500, 2500 AND 3500.

I PURCHASED A BRAND NEW 2015 SILVERADEO ON 7/24/15 AND AT ABOUT 700 MILES OR SO I NOTICED A BAD VIBRATION AS THE TRUCK WAS IN MOTION, TOOK IT BACK TO THE DEALER CAUSE I WAS VERY UPSET IT BEING AN $56,000.00 TRUCK AND ALL. THEY WANTED ME TO LEAVE THE TRUCK OVERNIGHT AND DID NOT OFFER ANY VEHICLE TO DRIVE SO I DID NOT LEAVE IT WITH THEM. SO I TOOK THE TRUCK TO RATFIELD TIRE AND HAD THE TIRE'S BALANCED,ALL 4 TIRE'S WERE OUT OF BALANCE, WHICH I PAID FOR OUT OF POCKET MYSELF NOT GM.... THIS DIDNOT FIX THE PROBLEM OF THE SEVERE VIBRATION GOING DOWN THE ROAD. I THEN TOOK THE TRUCK TO ANOTHER DEALER FOR THE VIBRATION, THEY TEST DROVE IT AND CONFIRMED THE VIBRATION, DID A ROAD FORCE BALANCE ON ALL 4 WHEELS, THEN REPLACED ALL TIRE'S, THIS ALSO HAS NOT FIXED THE PROBLEM,THE TRUCK IS STILL VIBRATING, THE ENTIRE SEAT JUST SHAKES, I AM PRESENTLY WAITING ON ANOTHER APPOINTMENT WITH DEALER. THE SERVICE MANAGER TOLD ME HIMSELF AFTER REPLACING ALL 4 TIRE'S THAT IT FELT LIKE A BALANCE ISSUE INSIDE THE MOTOR WHICH THERE IS NO FIX, NOW THAT IS CRAZY...I FELL THAT THIS TRUCK SHOULD BE REPLACED OR MY MONEY BACK ENTIRELY.THE TRUCK ONLY HAS A LITTLE OVER 2000 MILES CAUSE IT MAKES ME SICK TO DRIVE IT....

WHEN DRIVING 68MPH OR ABOVE THE WHOLE INSIDE OF THE VEHICLE VIBRATES LIKE A WHEEL IS OUT OF BALANCE. I WAS TOLD BY A CHEVY DEALER THAT THE DRIVE SHAFT IS WOBBLING & THAT'S CAUSING THE VIBRATION. AND GM SAYS IT'S NORMAL.

MY NAME IS [XXX] AND I AM THE OWNER OF THE 2015 CHEVROLET SILVERADO LT THAT I LEASED ON JANUARY 31, 2015 FROM HUNTINGTON CHEVROLET LOCATED AT 370 OAKWOOD RD, HUNTINGTON STATION, NY 11746 (877) 415-8697. I NOTICED IN MARCH WHEN THE WEATHER STARTED GETTING WARMER THAT THE AIR CONDITIONING WAS NOT WORKING PROPERLY. I BROUGHT THE VEHICLE INTO NEW ROCHELLE CHEVROLET LOCATED AT 291 MAIN ST, NEW ROCHELLE, NY 10801 (914) 730-9960 TO HAVE THE A/C SERVICED, AND IT WAS DISCOVERED THERE WAS NO FREON. AFTER HAVING THE FREON PUT INTO THE A/C SYSTEM I NOTICED VERY STRONG FUMES COMING INTO THE CABIN. THE VEHICLE WAS BROUGHT BACK INTO NEW ROCHELLE CHEVROLET TWICE TO HAVE THE PROBLEM SOLVED. I HAVE THE APPROPRIATE PAPERWORK TO VALIDATE THE SERVICE. THE 2 SERVICES AT NEW ROCHELLE DID NOT FIX THE PROBLEM. THE SMELL IS UNBEARABLE AND POSSIBLY TOXIC, AND STILL COMING INTO THE CABIN AS OF TODAY. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
