2014 GMC SIERRA 1500 Complaints

FOR THE PAST FEW WEEKS I HAVE HAD A POWER PROBLEM ON MY TRUCK. I HAVE GOT IN THE TRUCK AND NOTHING WAS ON AND ENGINE WOULDN'T CRANK. I WOULD GET OUT OF MY TRUCK AND WIGGLE THE NEGATIVE LINE ON THE BATTERY AND THE TRUCK WOULD REGAIN POWER. I CLEANED OFF ALL CORROSION (NOT ANYTHING SIGNIFICANT)THAT WAS ON THE CONNECTER. YESTERDAY AS I WAS TAKING A TURN INTO MY NEIGHBORHOOD THE TRUCK LOST ALL POWER. I WAS ABLE TO COST INTO A SAFE SPOT ON THE SIDE OF THE ROAD. I THEN POPED THE HOOD AND OPENED THE DOOR. WHEN I OPENED THE DOOR THE POWER CAME BACK ON. I CLOSED THE DOOR STARTED THE TRUCK AND HEADED TO MY HOUSE. I AM HAVING MY TRUCK TOWED TO THE NEAREST DEALER. IF THIS HAD HAPPENED TO ME ON THE HIGHWAY OR A MAIN ROAD IT COULD HAVE BEEN CATASTROPHIC. I HAVE DOON SOME RESEARCH AND FOUND A NUMBER OF VIDEOS AND FORUMS ON THIS SUBJECT AND IT SEEMS TO BE ON GM TRUCKS FROM 2014-2017. I AM NOT A MECHANIC, BUT I WORK IN IT AND AM VERY GOOD AT REASEARCH AND TROUBLESHOOTING ISSUES. MY INSTINCT IS TELLING ME IT IS THE NEGATIVE CONNECTION TO THE BATTERY.

COMPLETE LOSS OF POWER STEERING ALONG WITH SPEED CONTROL BEING DISABLED WHEN A TURN SIGNAL IS ACTIVATED. RECALL 17V414000 HAS ALREADY BEEN COMPLETED AND DID NOT CORRECT THE PROBLEM. BOTH OF THESE ISSUES OCCUR DURING THE SAME DRIVE CYCLE (ISSUES HAVE NOT HAPPENED SIMULTANEOUSLY BUT WILL BOTH OCCUR AT SOME POINT DURING THE SAME DRIVE CYCLE) THEY SEEM TO ONLY HAPPEN ON DRIVE CYCLES THAT LAST LONGER THAN 45 MINUTES.

HARD BRAKE PEDAL AT LOW SPEEDS CAUSING THE TRUCK TO NOT STOP. DEALERSHIP SAYS A FULL BRAKE SYSTEM REPLACEMENT IS NEEDED. I'VE SERACHED ONLINE AND THERE ARE SEVERAL PEOPLE HAVING THIS SAME ISSUE. IT SEEMS TO BE VERY COMMON, BUT NOTHING IS BEING DONE ABOUT IT BY GMC.

WHEN I TURN THE IGNITION TO START THE VEHICLE, IT ACTS AS IF THE BATTERY IS DRAINED. THEN THERE'S A MESSAGE THAT POPS UP BRIEFLY STATING "STABILITRAK". I'M CONCERNED THIS IS ABOUT TO GET MUCH WORSE. THE VEHICLE WAS STATIONARY AT THE TIME OF THE MESSAGE.

POWER STEERING RECALL. I HAVE BEEN IN TOUCH WITH MY NEARBY GMC DEALER FOR THE PAST 2 MONTHS ATTEMPTING TO GET THIS RECALL DEALT WITH AND FIXED. I NEED THIS RECALL TO BE RESOLVED NO LATER THAN 20 OCT 17 IN ORDER FOR MY VEHICLE TO BE SHIPPED TO MY NEW DUTY STATION IN ALASKA AS I WILL BE DOING A PCS (PERMANENT CHANGE OF STATION) FOR THE ARMY. IF IT CAN'T BE RESOLVED BY THEN I NEED SOME TYPE OF DOCUMENTATION SENT TO ME STATING IT CAN'T BE RESOLVED DUE TO GMC LACKING ABILITY TO FIX THE PROBLEM OR REMOVE THE RECALL FROM MY VEHICLE. PLEASE EMAIL THE DOCUMENTATION TO [XXX]. VERY RESPECTFULLY, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).'*JB

2014 GMC SIERRA 1500 DENALI PICK-UP TRUCK WITH 67,900 MILES: EXPERIENCED COMPLETE LOSS OF POWER BRAKES IN STOP-N-GO TRAFFIC SITUATION ON HIGHWAY. PROBLEM STARTED AS AN RARE ISSUE THAT WOULD CORRECT ITSELF AND PROGRESSIVELY GOT WORSE OVER A WEEK'S TIME. ISSUE OCCURRED WHEN IN TRAFFIC REQUIRING FREQUENT STOP-N-GO BRAKING. BRAKE PEDAL WENT COMPLETELY TO THE FLOOR AND STOPPING DISTANCES DRAMATICALLY INCREASED. HAD NO WAY TO MANUALLY APPLY THE BRAKES TO GET THEM FULLY ENGAGED. ULTIMATELY FORCED TO SHIFT INTO NEUTRAL AND APPLY PARKING BRAKE TO STOP. SUBSEQUENTLY FOUND GM BULLETIN #PIT5361B REFERRING TO OTHER CUSTOMER PROBLEMS WITH WEAK VACUUM AT BRAKE BOOSTER. THAT PROBLEM WAS CONFIRMED AND DIAGNOSED BY MY AUTOMOTIVE PROFESSIONAL. ENDED UP HAVING TO REPLACE BRAKE MASTER CYLINDER, VACUUM BOOSTER, VACUUM PUMP, VACUUM TUBE/PIPE AND 2 SERPENTINE BELTS FOR A GRAND TOTAL OF $1626.00 IN REPAIR WORK (SIMILAR AMOUNT TO THE OTHERS I FOUND WHO EXPERIENCED THIS ISSUE). TALKED TO MY GMC DEALER WHO CONFIRMED THAT THIS IS A RECOGNIZED ISSUE THAT HASN'T YET RISEN TO THE LEVEL OF A "SAFETY RECALL". HOWEVER, I WAS TOLD "STAY TUNED" BECAUSE THEY WOULDN'T BE SURPRISED IF A RECALL ON THE POWER BRAKE SYSTEM WAS RIGHT AROUND THE CORNER.

A/C CONDENSER FAILURE ON A 3-YEAR OLD TRUCK. $1,200 DEALER REPAIR AND GOOGLE SEARCH ONLINE SHOWS THIS IS A MASSIVE SYSTEMIC PROBLEM AMONGST OWNERS. NEED A RECALL

IN THE PAST 4 MONTHS, BEGINNING AT ABOUT 52K MILES, I STARTED RECEIVING MESSAGES ON MY TRUCK THAT SAID "STABILITY CONTROL" WAS OUT AND IT LOCKS THE FRONT LEFT WHEEL, LOSING ALL STEERING, THE RADIO AND THEN THE TRUCK GOES COMPLETELY DEAD. THE AC GOES ON/OFF AND THE HEADLIGHTS FLICKER. THIS IS ALWAYS AT LOW SPEEDS BETWEEN 5-10 MPH AND MOST COMMONLY WHEN MAKING A TURN. I HAD THE BATTERY REPLACED AT THE DEALERSHIP AND NOW THEY'RE TELLING ME I NEED A NEGATIVE BATTERY CABLE REPLACEMENT?

A/C CONDENSER HAS CRACK IN WELD ON RIGHT UPPER WELD AS DESCRIBED BY MANY OTHERS ON FORUMS FOR GMC AND CHEVY 2014-2017 TRUCKS. DATE BELOW IS JUST AN ESTIMATE AS WHEN THE ACTUAL DATE IS UNKNOWN. THE DATE IS WHEN AIR STARTED BLOWING WARM

AIR CONDITIONING SYSTEM WENT OUT. DEALERSHIP FOUND THAT THE LINE SET BETWEEN THE CONDENSER AND COMPRESSOR FAILED. DEALERSHIP STATED IT NEEDS A BRACKET TO FIX OR THIS WILL KEEP HAPPENING. APPROX. $700 TO FIX AND NOT COVERED UNDER VEHICLE WARRANTY.
