THE PROJECTOR HEAD LIGHTS ARE VERY POOR AT BEST. VERY LOW ILLUMINATION. IT IS VERY DIFFICULT TO SEE THE ROAD AT NIGHT. DRIVING IN SOME CONDITIONS IT IS EXTREMELY DIFFICULT TO SEE THE ROAD AND THE SIDES OF THE ROAD. WHEN MAKING A RIGHT HAND TURN THE DRIVER CANNOT SEE ANYTHING ON THE RIGHT. WHEN RAINING THE DRIVER CANNOT SEAT ALL. IT IS LIKE DRIVING A 1960 VINTAGE VEHICLE. THERE ARE MANY COMPLAINTS ON THE WEB. I NOTIFIED GMC ABOUT THIS ISSUE. THE RESPONSE IS THE LIGHTS WORK AS DESIGNED. THIS IS A TERRIBLE DESIGN.THERE WILL BE ACCIDENTS DUE TO THIS ISSUE. GM SHOULD BE PROACTIVE BEFORE THERE ARE FATALITIES. I HOPE THAT NOTIFYING YOU THAT YOU WILL HELP SOLVE THIS. *TR

2015 GMC SIERRA 6-SPEED AUTOMATIC TRANSMISSION FAILURE @ 1800 MILES. AS I WAS DECELERATING FROM APPROXIMATELY 30 MPH TO MAKE A TURN INTO A ROAD THE TRANSMISSION DOWNSHIFTED AS EXPECTED TO LOW GEAR. AS I ACCELERATED THE TRANSMISSION SHIFTED TO 2ND NORMALLY. AT THIS POINT THE TRANSMISSION SHOULD HAVE SHIFTED INTO 3RD GEAR BUT THE TACHOMETER JUMPED TO 3000RPM BEFORE I REALIZED THAT THE TRANSMISSION HAD SHIFTED INTO WHAT SEEMED LIKE NEUTRAL. THIS LEFT ME BLOCKING TRAFFIC WITH A TRUCK THAT WOULD NOT GO OVER 20 MPH. WHEN I SLOWED SUFFICIENTLY THE TRANSMISSION WOULD PICK UP 2ND GEAR AGAIN. BEING CLOSE TO HOME I WAS ABLE TO LIMP HOME. WHEN I REACHED HOME I PAST MY DRIVEWAY AND WENT TO BACK IN AS I USUALLY DO. THE TRANSMISSION WOULD NOT PICK UP REVERSE! BY THIS TIME A CHECK ENGINE LIGHT CAME ON. I THEN HAD TO DRIVE ABOUT A MILE DOWN THE ROAD TO FIND A PLACE TO MAKE A U TURN SO I COULD PULL IT INTO MY DRIVEWAY. THE TRUCK WAS TOWED TO THE DEALERSHIP WHERE A MECHANIC EXPERIENCED THE SAME PROBLEM ON A TEST DRIVE. (HE HAD TO PUSH THE TRUCK BACKWARDS BY HAND TO BE ABLE TO RETURN TO THE SHOP.) CURRENTLY THE TRANSMISSION HAS BEEN REMOVED FROM MY BRAND NEW TRUCK PENDING INVESTIGATION. IT HAS ONLY TO GEARS 1ST AND 2ND. THIS IS A SERIOUS FAILURE THAT COULD HAVE HAPPENED WHILE MERGING INTO TRAFFIC ON THE INTERSTATE. LUCKILY I WAS ON A BACK ROAD IN THE MIDDLE OF WINTER! *TR

A WEEK LATER AFTER BUYING A NEW 2015 GMC SIERRA DELANI FROM ED MORSE GMC 'SAWGRASS I TOOK IT TO A TRUCK ACCESSORY COMPANY TO ORDER A NEW BED (TONNEAU) COVER. THEY TOOK THE ORDER AND TOOK A PICTURE OF THE SERVICE PARTS IDENTIFICATION LABEL, LOCATED IN THE TRUCK GLOVE BOX FOR THE PURPOSE OF ORDERING THE PART AND COLOR. THIS IS THE ONLY PLACE IN THE TRUCK THAT IDENTIFIES THE PARTS AND COLOR FOR THIS PARTICULAR VEHICLE. I AM ENCLOSING A PICTURE FOR YOUR REVIEW. TEN DAYS LATER THE COVER ARRIVED AND WHEN I WENT TO THE COMPANY TO HAVE IT INSTALLED, THEY REMOVED THE WRAPPING TO SHOW ME THE COVER AND WE FOUND OUT THAT IT WAS NOT THE RIGHT COLOR. THE COVER WAS WHITE INSTEAD OF BLACK. THE COMPANY MANAGER CHECKED THE ORDER TWICE TO VERIFY THAT THEY HAD ORDERED IT CORRECTLY AND THAT HAD THE CORRECT DECAL INFORMATION. THIS IS WHEN WE FOUND OUT THE CODE INFORMATION IN THE SERVICE PARTS IDENTIFICATION LABEL IN MY TRUCK WAS INCORRECT, THE CODE FOR THE PAINT SAID WHITE NOT ONYX BLACK AS THE COLOR OF MY VEHICLE. THEY SAID WE CAN RE-ORDER THE TOP IN THE RIGHT COLOR, BUT WILL NOT BE ABLE TO REFUND YOUR DEPOSIT BECAUSE IT WAS NOT THEIR FAULT BUT GMC. WE CONTACTED GMC ON 2/11 TALKED TO SHELLY AND SHE SAID THEY COULD NOT HELP US; THEY WOULD NOT EVEN PUT A MANAGER ON THE PHONE. THEN WE CONTACTED THE DEALER WHO HAD SOLD US THE TRUCK, ED MORSE GMC-SAWGRASS, FL. THE DEALER TOLD US THAT HAD CONTACTED GMC BUT THEY WOULD NOT DO ANYTHING ABOUT THE WRONG SERVICE PART DECAL WE WANT GMC TO FIX THIS PROBLEM REPLACING THE DECAL BECAUSE THE INFORMATION IN THIS DECAL IS VITAL TO ORDER CORRECT PARTS FOR THIS VEHICLE AND WE KNOW THAT SOONER OR LATER WE ARE GOING TO NEED THE CORRECT INFORMATION. IF THEY CAN'T FIX THIS PROBLEM THEY SHOULD REPLACE THE TRUCK.

I HAVE BEEN HAVING A PROBLEM WITH THE TRAILER BRAKE CONTROLLER ON MY K3500 TRUCK. RECENTLY THE MESSAGE "CHECK TRAILER WIRING" HAS BEEN COMING ON FREQUENTLY. AT THE SAME TIME, THE BRAKING CONTROLLER SHUTS OFF POWER TO THE TRAILER BRAKES. THIS HAS RESULTED IN A VERY UNSAFE CONDITION, ESPECIALLY WITH A TRAILER THAT WEIGHS OVER 14,000 POUNDS. THIS HAS BEEN GOING ON FOR 6 MONTHS NOW. REPEATED ATTEMPTS BY BOTH THE GMC DEALER AND THE TRAILER DEALER HAVE FAILED TO RESOLVE THE PROBLEM. I HAVE BEEN TOLD, BY THE DEALER, THAT THE PROBLEM STARTED APPROXIMATELY WITH THE 2014 MODELS. THE BRAKE CONTROLLER HAS BEEN UPGRADED, AND MADE MUCH MORE SENSITIVE TO SLIGHT DEVIATIONS IN THE TRAILER SYSTEM, CAUSING THE CONTROLLER TO "SHUT OFF" SO TO SPEAK. WHILE THIS WOULDN'T BE A BIG ISSUE NORMALLY, WHEN IT SHUTS OFF, YOU LOSE ALL BRAKING ABILITY TO THE TRAILER RESULTING IN AN UNSAFE CONDITION. THERE IS NO WAY TO OVERRIDE THIS AND ACTIVATE THE BRAKES. WHAT SEEMS TO BE HAPPENING IS A VERY SLIGHT DEVIATION IN THE RESISTANCE IN THE TRAILER BRAKE SYSTEM (BY 1 OHM OR LESS) AND THAT CAUSES THE "SHUTDOWN" IN THE CONTROLLER. TRAILER BRAKES WOULD WORK, IF THEY COULD GET POWER. BUT, THE CONTROLLER HAS SHUT DOWN, SO NO POWER. MYSELF (AND THE TRAILER SHOP) HAVE BEEN CHECKING THE INTERNET AND FINDING THAT THIS IS NOT AN ISOLATED INCIDENT. IT APPEARS TO BE HAPPENING WITH ALL THE BIG THREE MANUFACTURER TRUCKS, SINCE ABOUT 2014. PEOPLE HAVE BEEN COMING UP WITH SOME RATHER "CREATIVE" WAYS AROUND THIS, IN SOME CASES ELIMINATING THE ORIGINAL SYSTEM ENTIRELY. THIS IS JUST NOT ACCEPTABLE. AGAIN, THIS "NEW SYSTEM THE BIG THREE ARE PUTTING IN IS FAR WORSE THAT THE OLD, SIMPLY BECAUSE IT HAS NO ROOM FOR FORGIVENESS IN A TRAILER SYSTEM THAT MIGHT WORK OTHERWISE, BUT HAS A SLIGHT DEVIATION IN WHAT IS CONSIDERED "ACCEPTABLE" TO THE CONTROLLER. AT THE VERY LEAST, THERE SHOULD BE A FAIL SAFE METHOD.
