POWER TRAIN
TOWING A 5900# RV TRAILER WITHIN THE SPECIFIED 7600# TOW WEIGHT CAPACITY, CAUSED THE TRANSMISSION TO OVERHEAT AND FREE SPIN WITHIN 10 MILES OF TRAVEL. TRANSMISSION OVERHEATING OCCURRED WHEN TOWING (285+), WHEN NOT TOWING BUT IN TOW MODE (264), & WHEN DRIVING (241). DEALER AND GMC TECH'S DO NOT HAVE A CORRECTION FOR THE TRANSMISSION OPERATING ABOVE RANGE. V6 ENGINE W 6 SPEED AUTOMATIC TRANSMISSION. TRAVELING AT 60MPH. WEATHER TEMPERATURE LOW 80'S. LEAVING THE OWNER IN THE ROAD WITH THEIR RV WAITING FOR 20 MINUTES FOR THE TRANSMISSION TO COOL DOWN SO IT CAN BE MOVED OFF THE ROAD, IS NOT SAFE.

ELECTRICAL SYSTEM
WHEN REVERSE IS ACTIVATED AT NIGHT, THE BACKUP CAMERA COMES ON AT FULL BRIGHTNESS AND IS NOT DIMMABLE. THE BRIGHT SCREEN PREVENTS VIEW OF THE PASSENGER SIDE MIRROR AND SIGNIFICANTLY REDUCES VISIBILITY IN THE DRIVER SIDE MIRROR WHILE REVERSING. THE SCREEN CANNOT BE DEACTIVATED AND BLINDS THE DRIVER. THIS IS AN ONGOING ISSUE.

SERVICE BRAKES, WHEELS, UNKNOWN OR OTHER
WHILE DRIVING DOWN A MOUNTAIN ROAD WITH A 5TH WHEEL ATTACHED IT APPEARED THAT THE REAR BRAKES ON THE DRIVERS SIDE WERE SMOKING, I PULLED OVER TO ALLOW IT TO COOL. WE FOUND A GMC DEALERSHIP AND PROCEEDED THERE VERY SLOWLY STOPPING A NUMBER OF TIMES TO ALLOW THE BRAKES TO COOL DOWN. 2 MILES SHORT OF GMC, THERE WAS A LOUD POP AND A TIRE HAD BLOWN. WE PULLED OVER AND WHILE CALLING ROADSIDE ASSISTANCE NOTICED FIRE UNDER THE TRUCK. WE PUT IT OUT WITH A FIRE EXTINGUISHER BEFORE THE FIRE DEPARTMENT ARRIVED. WE WERE TOWED TO THE DEALERSHIP. THE BRAKE CALIPER CAME APART, THE REAR AXLE BROKE (POSSIBLY MELTED FROM HEAT AND FIRE?). GM INITIALLY STATED 4 DAYS TO REPAIR, NOW THEY THEY ARE SAYING 3 WEEKS AS THEY HAVE TO BUILD A NEW AXLE. IF WE HAD NOT HAD THE EXTINGUISHER THE TRUCK, RV AND MEADOW WOULD HAVE ALL GONE UP IN FLAMES AND WHO KNOWS THE DISASTER THAT COULD HAVE OCCURRED IF THIS HAPPENED ON THE MOUNTAIN ROAD. THIS VEHICLE ONLY HAS 17,000 MILES, 11 MONTHS OLD AND HAS HAD ALL ROUTINE MAINTENANCE PERFORMED AT GMC DEALERS. I HAVE MORE PICTURES BUT AM UNABLE TO UPLOAD THEM.

STEERING
ON AUGUST 24TH 2018 WHILE DRIVING MY NEW 2017 GMC SIERRA THRU WEST BRANCH MICHIGAN THE POWER STEERING FAILED AND COMPLETELY WENT OUT. I COULD BARELY GET THE VEHICLE OFF OF THE ROAD SAFELY. STEERING THE TRUCK WAS ALMOST IMPOSSIBLE. I CALLED THE GMC DEALER AND THE SERVICE DEPARTMENT PERSON SAID TO TURN OFF THE VEHICLE, WAIT A BIT AND RESTART THE TRUCK. I DID THIS AND EVERYTHING REENGAGED. A WHILE LATER DOWN THE ROAD IT HAPPENED AGAIN. POWER STEERING SHUT DOWN. THIS VEHICLE IS A REPLACEMENT VEHICLE WE CHOSE AFTER OUR NEW 2016 GMC SIERRA CONTINUED TO SHUT DOWN OVER 30 TIMES WITH ECM PROBLEMS WHILE DRIVING AT ALL SPEEDS. MY WIFE WAS TERRIFIED AND RELUCTANT TO EVER DRIVE THAT VEHICLE AFTER THAT. AFTER MANY HURDLES, GMC DECIDED TO EXCHANGE THE TRUCK WITH OUR CURRENT 2017 GMC SIERRA THAT WE HAVE NOW. THIS 2017 GMC SIERRA HAS LOST ITS POWER STEERING OVER15 TIMES WHILE UNDERWAY DRIVING. THANK GOD IT WASN'T EVER MY WIFE DRIVING. ITS BAD ENOUGH FOR HER TO BE A PASSENGER NOW WHEN THE STEERING GOES OUT AS WELL. SHE IS TERRIFIED, AND I AM VERY LEARY AND CONCERNED ABOUT THIS HAPPENING AT ANY TIME AT ANY SPEED WITHOUT WARNING. IT HAS ALSO HAPPENED AT HIGHER SPEEDS. ON SEPTEMBER 1, 2018 WHILE MAKING A RIGHT HAND TURN FROM M-65 ON TO MAPLE RIDGE RD WHITTEMORE, MICHIGAN, THE POWER STEERING WENT OUT AGAIN AND THE STEERING WHEEL WHIPPED BACK TO THE LEFT SO HARD AND FAST I COULD BARELY CONTROL THE VEHICLE TO MANEUVER. I ALSO SUFFERED A SERIOUS LEFT SHOULDER INJURY THAT I CONTINUE TO SUFFER WITH. MY WIFE IS LITERALLY DEATHLY AFRAID TO DRIVE THIS TRUCK. I AM AFRAID THAT I MAY KILL SOMEONE OR MYSELF AND WIFE WITH THIS DANGEROUS TRUCK. WHILE DRIVING THE VEHICLE TO THE DEALER AFTER THE POWER STEERING RESET AFTER I TURN IT OFF, FROM THE DAY BEFORE. IT LOST POWER STEERING AGAIN AT 65 MPH. REPAIRS HAVE BEEN MADE TO THE ECM AND POWER STEERING MODULE FROM DEALER PATSY LOU WILLIAMSON BUICK GMC

POWER TRAIN
THE "CHEVY SAKE". AT SPEEDS OVER 70MPH EXCESSIVE VIBRATION INSIDE THE VEHICLE. THIS IS WELL DOCUMENTED ON-LINE, PARTICULARLY VARIOUS GM FORUMS AND YOU TUBE VIDEOS. IT IS MY UNDERSTANDING THAT GM DENIES IT IS A PROBLEM, BUT THEY HAVE BEEN DOING SOME BUY BACKS AND IF YOU READ SOME OF THE DEALER BLOGS IT IS EVIDENT THAT GM KNOWS IT IS A PROBLEM.

POWER TRAIN
THIS TRUCK IS A 3500 HD. I WAS PULLING A CAMPER ON A 1100 MILE TRIP. WITH 50 MILES LEFT I NOTICED THAT THE TRUCK WAS LEAKING TRANSMISSION FLUID FROM UNDER THE TRANSMISSION COOLER. UPON FURTHER INVESTIGATION I FOUND THAT THE RETURN HOSE FROM THE TRANS COOLER WAS POSITIONED SO THE IT RUBBED ON A FRAME COMPONENT WHICH CAUSED A HOLE TO RUB IN THE ALUMINUM TRANS COOLANT RETURN LINE. I NOTICED THIS WHEN THE TRUCK WAS PARKED RUNNING AT A REST AREA FOR AN HOUR BUT IT WAS OBVIOUSLY AN ONGOING ISSUE. HAD I NOT NOTICED IT WHEN I DID THIS CONDITION COULD HAVE CAUSED CATASTROPHIC FAILURE OF THE TRANSMISSION. THE DEALER SAYS THERE IS NO RECALL AND IT IS NOT UNDER WARRANTY. I CONSIDER THIS TO BE A SERIOUS DESIGN FLAW AND A MAJOR SAFETY ISSUE. I WAS ABLE TO GET TO MY DELIVERY STOP AND GET THE LINE PATCHED. IT IS AT THE DEALER FOR REPAIRS RIGHT NOW.

POWER TRAIN
I BOUGHT THIS TRUCK USED WITH 12,918 MILES ON IT, APRIL 2018. WHEN DRIVING(ESPECIALLY ON HIGHWAY), AND CHANGING SPEEDS, TRANSMISSION CLUNKS AND LURCHES-AUTOMATIC TRANSMISSION. IT SOUNDS AND FEELS AS IF DRIVE TRAIN WILL FALL OUT. I HAVE TAKEN IT TO DEALER TWICE. THE FIRST TIME, THEY KEPT IT FOR 3 DAYS, THE SECOND TIME, FOR ONE. THE MECHANIC IS ABLE TO REPLICATE THE NOISE/LURCHING, BUT THEY ARE UNABLE TO FIND A CAUSE OR CORRECTION. THEY TELL ME IT IS NOT DANGEROUS, BUT I AM CONCERNED THAT THE NOISE/MOVEMENT, COULD CAUSE MYSELF OR ANOTHER FAMILY MEMBER TO SWERVE OR BRAKE HARD AND CAUSE AN ACCIDENT. THE MECHANIC HAS TRIED "UPDATING THE SOFTWARE" BUT THAT DID NOT FIX IT. SEVERAL OTHER GMC SIERRA OWNERS TELL ME THEY HAVE HAD SAME PROBLEM.

WHEN DRIVING AT SLOW PARKING LOT SPEEDS OR WHEN COMING TO A COMPLETE STOP THE VEHICLE INTERMITTENTLY LUNGES, SURGES OR JOLTS, CAUSING THE VEHICLE TO MOVE FORWARD OR BACKWARDS UNANTICIPATED. SOMETIMES THE JOLT FEELS LIKE ANOTHER VEHICLE HAS HIT THIS VEHICLE FROM THE REAR, AGAIN CAUSING IT TO LUNGE FORWARD.

SERVICE BRAKES, VEHICLE SPEED CONTROL, STEERING
VEHICLE HAS HARD SHIFT AT 5-6 MPH. DEALER STATED COULD NOT FIND ISSUE, AND REFLASHED TCM.APPROX MONTH LATER, AT 10K MILES, TRUCK HARD SHIFTED FROM RED LIGHT ON HIGHWAY, ONCE UP TO 45 MPH, SHUTDOWN. STEERING WHEEL LOCKED UP, NO BRAKES, NO CONTROL OF VEHICLE AT 45-50 MPH.DEALER KEPT FOR ONE WEEK, STATED LOOSE CABLE ON STARTER FROM BATTERY. EXACTLY 1K MILES LATER (5 WEEKS), NOW AT 11K MILES, TRUCK HARD SHIFTED AT 5-6MPH, AND AT 45-50 MPH TRUCK TRIED TO SHIFT IN 4WD. ALL LIGHTS ON DASH CAME ON AS A RESULT. DEALER HAS CURRENTLY HAD THE TRUCK FOR TWO WEEKS AND CAN NOT FIND ISSUE. THEY SUPPOSEDLY CONSULTED GM, AND INSTEAD OF SENDING AN EXPERT TECH TO HELP DEALER FIND ISSUE, ADVISED DEALER TO REPLACE ECM. REPLACING ECM IS THE GENERAL ANSWER TO NOT SURE WHAT IS WRONG. THIS TRUCK IS A SAFETY ISSUE, AS WHEN IT SHUTS OFF GOING 45-50 MPH THERE IS NO CONTROL OR BRAKES OPERATIONAL ON THE VEHICLE. GM WILL REPLACE THE ECM, AND JUST LIKE RIGHT NOW, WILL NOT BE ABLE TO REPLICATE THE PROBLEM, AND EXPECT ME AS THE CONSUMER TO TAKE DELIVERY BACK OF THE VEHICLE. CURRENTLY ALL OF MY DOCUMENTATION IS IN THE DASH OF THIS TRUCK, AT THE DEALERSHIP. TRYING TO DETERMINE HOW MYSELF AS THE CONSUMER CAN HELP ENSURE THIS SAFETY ISSUE IS CORRECTED, AND NOT PASSED ON.

STEERING
I WAS TURNING AROUND A CURB AT A FAST FOOD WHEN SUDDENLY THE STEERING WHEEL JERKED OUT OF MY HANDS THE OPPOSITE WAY I WAS TURNING THE SLIGHTLY BACK AGAIN. WHEN I TRIED TO REGAIN CONTROL IT DID IT AGAIN. I PAUSED AND WAS THEN PERMITTED TO COMPLETE MY TURN. I THEN EXPERIENCED IT AGAIN ABOUT A WEEK LATER WHILE BACKING INTO A PARKING SPOT. UPON COMPLETION OF MY APPOINTMENT I IMMEDIATELY DROVE STRAIGHT TO THE DEALERSHIP WHERE I HAD PURCHASED THE TRUCK NEW A YEAR AGO AND INQUIRED OF ANY RECALLS OR PROBLEMS OF THE STEERING DOING THIS AND THE SERVICE GENTLEMAN LOOKED ON THE COMPUTER AND SAID NO. I HAVE MADE AN APPOINTMENT FOR THE FOLLOWING WEEK TO TAKE IT IN TO DIAGNOSIS THE PROBLEM. I WILL NOT KNOW THE OUT COME TILL THEN, BUT SINCE IT HAS HAPPENED TWO MORE TIMES. THE SITUATION SEEMS TO HAPPEN AT SLOW SPEED( THANK GOD) AND WHILE TURNING SHARPLY. IT IS DANGEROUS AT ANYTIME WHEN THE VEHICLE IS NOT UNDER CONTROL.

SEAT BELTS
I HAVE HAD MY VEHICLE IN FOR REPAIR SEVERAL TIME ON THE PASSENGER SEAT BELT DOES NOT PROVIDE A WARNING WHEN DISCONNECTED WHILE OPERATING. THE DEALER IS TELLING ME THAT IS WAS NOT INSTALLED IN THAT MODEL AND YEAR. I DO NOT FEEL SAFE HAVE A PASSENGER IN THE SEAT WITH OUT THE WARNING LETTING ME KNOW THAT ARE UNBUCKLED. MY WIFE RODE FOR OVER 200 MILES WITH IT DISCONNECTED BY NO FAULT OF HER OWN. I FEEL THIS IS A SAFETY ISSUES AND NEED ADDRESSED WITH GMC THE CHEVY SAME YEAR IT WORKS.

SERVICE BRAKES
I ALMOST KILLED A KID TODAY PARKING FOR A BASEBALL GAME. I WAS TRAVELING SLOWLY AND PARKING WHEN MY BRAKES BECAME HARD TO PUSH AND FAILED. TRUCK WENT OVER CURB AND TOWARD KID PUTTING ON HIS CLEATS AND NOT FACING ME. I WAS ABLE TO PUSH AS HARD AS I COULD AND IT STOPPED. I BACKED UP AND BRAKES WORKED AGAIN. I HAVE 46,000 MILES ON THE TRUCK. I AM NOW AFRAID TO DRIVE IT, BUT IT SEEMS THEY ARE WORKING AGAIN. IF THIS IS COMMON, GMC NEEDS TO TAKE CARE OF THIS. SOMEONE WILL SOON BE HURT SERIOUSLY!

EXTERIOR LIGHTING
DURING NIGHT OPERATION WITH THE INSTRUMENT CLUSTER ADJUSTED TO PROPER BRIGHTNESS THE INTELLILINK SCREEN IS DANGEROUSLY BRIGHT. THE INTELLILINK SCREEN DOES NOT HAVE AN INDEPENDENT BRIGHTNESS CONTROL FROM THE DIMMER. WHEN SET TO OFF IN AN ATTEMPT TO MITIGATE THE PROBLEM, THE INTELLILINK SCREEN REACTIVATES WITH SUBSYSTEM ADJUSTMENT, E.G. TEMPERATURE ADJUSTMENT, ABSOLUTELY DESTROYING NIGHT VISION OF THE DRIVER. IF ADJUSTING THE BRIGHTNESS LEVEL TO ACCEPTABLE FOR THE CENTER CONSOLE LIGHTING AND INTELLILINK THE INSTRUMENT CLUSTER IS SO DIM THAT IT REQUIRES UNSAFE LEVELS OF DRIVER ATTENTION TO PROCESS THE DIMLY LIT INFORMATION. IN ADDITION THE BACKUP CAMERA IS ALSO TOO BRIGHT AS WELL IN REVERSE CAUSING A DISTRACTION. GM CUSTOMER SUPPORT WAS NOTIFIED AND CONFIRMED THIS WAS AS DESIGNED WITHOUT A DIMMER AND THEY WILL FILE A COMPLAINT AS PER MY REQUEST.
