EXTERIOR LIGHTING
I WISH TO COMPLAIN ABOUT THE HEADLIGHTS ON THIS VEHICLE. THEY ARE REALLY TERRIBLE. LOW BEAM DOES NOT PROJECT FAR ENOUGH, AND HIGH BEAM SEEMS TO ILLUMINATE ROAD SIGNS AT A DISTANCE, BUT NOT ADEQUATE FOR THEIR PURPOSE. SEEMS AS THEY ARE MORE OF A SPOTLIGHT THAN A HEADLIGHT. THESE ARE THE MOST UNSAFE HEADLIGHTS I HAVE EVER HAD IN 43 YEARS OF DRIVING. AGAIN, THERE WAS NO ACCIDENT THANKFULLY, AND I JUST WISH TO FILE MY COMPLAINT AND CONCERN. THANK YOU. *TR

STRUCTURE:FRAME AND MEMBERS:UNDERBODY SHIELDS, SUSPENSION
SEVERE FRAME CORROSION (ALL SECTIONS OF FRAME). THE UNDERCOATING IS FLAKING OFF IN ALL SECTIONS EXPOSING BARE METAL WHICH IS RAPIDLY CORRODING THROUGHOUT THE FRAME. THE TRUCK IS IN MINT CONDITION INSIDE AND OUT OTHER THAN THIS ISSUE. GM STATED THAT "RUST" IS NOT COVERED UNDER MY ACTIVE WARRANTY. THIS IS A FAULTY COATING APPLICATION OR A FAULTY METAL ISSUE. THIS VEHICLE WILL BE UNSAFE SOON AND IT JUST HIT 12,000 MILES. I PURCHASED THIS "GM CERTIFIED PRE-OWNED" TRUCK TWO WEEKS AGO FROM THE GM DEALERSHIP AND JUST REALIZED THAT MANY, MANY COMPLAINTS HAVE BEEN FILED FOR THIS VERY ISSUE. *TR

POWER TRAIN
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

EXTERIOR LIGHTING
THE PROJECTION STYLE HEADLIGHTS DO NOT ILLUMINATE THE ROADWAY SUFFICIENTLY ENOUGH AT NIGHT TO TRAVEL MORE THAN 30 MPH. WHILE TRAVELING ON RURAL AND MOUNTAIN ROADS YOU CANNOT SEE FAR ENOUGH TO SEE OBSTRUCTIONS, WILDLIFE OR PEDESTRIANS AT NIGHT. THE HORIZONTAL CUTOFF LINE OF THE LIGHTS ON LOW BEAM DOES NOT ALLOW YOU TO SEE THE TOPS OF SMALL RISES IN THE ROADWAY AS CLOSE AS 30 FEET AWAY. WITH THIS STYLE OF PROJECTION LIGHTING THERE IS NO SPILLAGE OF LIGHT ABOVE ESTABLISHED LIGHT SHADE COVER SETTING ON LOW BEAMS. IT IS COMPLETELY DARK ABOVE THIS LINE WITH LOW BEAMS SELECTED. THIS DOES NOT GIVE THE DRIVER A CHANCE TO SEE OBJECTS IN THE ROADWAY AT A SAFE DISTANCE TO ALLOW FOR SAFE BRAKING OR AVOIDANCE. THE HIGH BEAM SETTING IS PITIFULLY WEAK IN INTENSITY. I MUST STRAIN TO SEE OUT AT THE DISTANCE NECESSARY TO STOP AT HIGHWAY SPEEDS. THIS MEANS I MUST TRAVEL WITH HIGH BEAMS ON WHEN FACING ONCOMING TRAFFIC ON THE INTERSTATES. I HAD TWO PREVIOUS TRUCKS OF THIS SAME BRAND THAT HAD WONDERFUL LIGHTING AND I SURE WISH I HAD THAT LIGHTING ON THIS TRUCK. GM IS DOING THE MOTORING PUBLIC A MAJOR DISSERVICE WITH THIS LIGHTING PACKAGE AND ENDANGERING ANYONE AND ANYTHING THAT MAY BE ON THE ROAD AHEAD OF THEIR TRUCKS! *TR

EXTERIOR LIGHTING
I PURCHASED 2014 GMC SIERRA 1500 ON OCTOBER 20TH 2014 AT THIS TIME IT HAS 1700 MILES ON IT. THE FIRST TIME OF MAYBE 3 TIMES THAT I DROVE THE VEHICLE AT NIGHT I WAS DISCOURAGED WITH THE HEADLIGHTS. I COULD BARELY SEE THE ROADWAY AND I COMMENTED TO MY FIANCE THAT THEY WERE TERRIBLE AND THAT I WAS AFRAID I WOULD HIT SOMETHING. I HAPPENED TO LOOK FOR RECALLS ON THE INTERNET AND NOTICED THAT THERE ARE MANY COMPLAINTS REGARDING THIS ISSUE. I AM SHOCKED THAT THERE HAS NOT BEEN ANYTHING TO CORRECT THE PROBLEM. I AM HESITANT TO DRIVE IT AT NIGHT. SOMETHING NEEDS TO BE DONE BEFORE SOMEONE GETS SERIOUSLY INJURED. *TR

FUEL/PROPULSION SYSTEM
WE WERE DRIVING ON A 2 LANE HIGHWAY GOING 60MPH WHEN ALL OF A SUDDEN THE TRUCK WENT TO 20MPH. THE VEHICLE BEHIND ME ALMOST REAR ENDED ME. I PULLED OVER TO THE SHOULDER AND SAW THE CHECK ENGINE LIGHT WAS ON, AND ALSO THERE WERE OTHER MESSAGES SAYING THAT TRACTION CONTROL WAS OUT, VEHICLE STABILITY WAS OUT, ETC. I WAS A COUPLE OF MILES AWAY FROM THE DEALERSHIP SO I CALLED THEM. LUCKILY THEY WERE OPEN ON SATURDAY. I TOOK IT THERE AND HAD THE THROTTLE BODY REPLACED. THE TRUCK HAS ONLY 18,500 MILES ON IT. THE SERVICE MAN SAID THERE WERE NO RECALLS OR SERVICE BULLETINS FOR THIS PROBLEM. THE LITTLE RESEARCH I HAVE DONE SHOWS THAT MANY OTHER OWNERS HAVE HAD THIS SAME PROBLEM. *TR

POWER TRAIN, ENGINE
GENERAL MOTORS GMC SIERRA DURAMAX EQUIPPED PICK UP TRUCKS (LMM SERIES) HAVE AN ISSUE WITH LEAKING TRANSMISSION COOLING LINES WHERE THE RUBBER HOSES ARE CRIMPED TO THE STEEL CONNECTORS. THE PROBLEM IS A FIRE HAZARD DUE TO LEAKING TRANSMISSION FLUID. GM HAS ALREADY ISSUED REPLACEMENT OF THESE HOSES FOR THE 2008 MODEL YEAR. IN 2007 GM HAD A SPLIT YEAR OFFERING FOR THE DURAMAX. THE 2007 VERSION WAS A SERIES LBZ. IN THE SECOND HALF OF 2007 (DUE TO EMISSIONS REQUIREMENTS) GMC INTRODUCED THE MODEL YEAR DESIGNATION 2007.5. THE 2007.5 WERE THE FIRST OF THE LMM SERIES. THE 2007.5 ARE IDENTICAL TO MODEL YEAR 2008. THE 2007.5 LMM SERIES HAVE THE SAME LEAKING TRANSMISSION COOLER LINES AND SHOULD BE INCLUDED IN THE SAME DECISION AS THE 2008 MODELS. SINCE THE 2007.5 SHOW UP AS "2007" MODEL YEAR THEY HAVE NOT BEEN INCLUDED. GM HAS MISSED THIS SMALL GROUP OF 1/2 YEAR VEHICLES (I BELIEVE AN OVERSIGHT) IN THE HOSE REPLACE RECALL. SINCE THIS ISSUE HAS ALREADY BEEN IDENTIFIED FOR 2008 VEHICLES THE SAME ISSUE APPLIES FOR 2007.5 MODELS. THEY SHOULD ALSO BE INCLUDED BUT CURRENTLY ARE NOT. I'M HOPING THAT THE AWARENESS OF THE UNUSUAL SPLIT YEAR MODELS (SERIES LMM) IS REALIZED AND THEIR VIN NUMBERS ADDED TO THE RECALL. *TR

ELECTRONIC STABILITY CONTROL (ESC)
I WAS SITTING IN A PARKING LOT WITH MY TRUCK RUNNING, I NOTICED MY RPM'S WERE STARTING TO FLUTTER AND MY OIL PRESSURE WAS DOING THE SAME. AFTER A FEW MINUTES OR SO MY TRUCK STARTED SHAKING AND THE RPM'S WERE STILL FLUTTERING. WHILE THIS HAPPENED MY CHECK ENGINE LIGHT CAME ON AND IT FLASHED "ENGINE POWER REDUCED" "SERVICE TRACTION" AND THEN "SERVICE STABILITRAK." I THEN SHUT MY TRUCK OFF AND WAITED APPROX. 25 MINUTES. WHEN I TURNED MY TRUCK BACK ON THE RPM'S WERE STILL FLUTTERING BUT THE TRUCK WAS NO LONGER SHAKING. I TOOK MY TRUCK TO AUTO-ZONE THE FOLLOWING MORNING AND HAD A DIAGNOSTIC DONE, THE TROUBLE CODE HAD TO DO WITH THE THROTTLE POSITION SENSOR. AFTER THAT MY COMPUTER MUST HAVE RESET ITSELF AND EVERYTHING WENT BACK TO RUNNING NORMALLY UNTIL ABOUT TWO WEEKS LATER THE SAME THING HAPPENED AGAIN. *TR

EXTERIOR LIGHTING
THERE TRULY IS NO ACCIDENT AT THIS TIME. HOWEVER ... IF THIS CONDITION ISN'T CORRECTED, THERE WILL BE ACCIDENTS. THESE MAY RESULT IN NOT ONLY LOSS OF LIFE OR PROPERTY, BUT POSSIBLE CRIMINAL PROSECUTION. THE ISSUE: THE PROJECTOR HEADLAMP DESIGN OF THE 2014 GMC SIERRA IS EXTREMELY SUBPAR FOR LIGHTING THE ROADWAY AHEAD OF YOU. INDIVIDUALS, IN ORDER TO NOT "OUTDRIVE" THEIR LIGHTS, WOULD PROBABLY HAVE TO GO BELOW POSTED MINIMUM SPEED LIMITS ON HIGHWAYS, PRESENTING YET ANOTHER ISSUE FOR THE DRIVER AS WELL AS THOSE WHO WOULD APPROACH FROM THE REAR IN NIGHTTIME DRIVING CONDITIONS. I CONTACTED GMC ... AWARE OF THE ISSUE. NO HELP AT THIS TIME. I GOT THE IMPRESSION FROM THE OPERATOR THAT "NOT ENOUGH PEOPLE HAVE FILED COMPLAINTS." I'M GUESSING THAT WHEN THE CATASTROPHIC AND TRAGIC HAPPENS, IT WILL NOT MATTER THAT NOT ENOUGH PEOPLE FILED COMPLAINTS ... OFFICIALLY. SLIGHT RESEARCH ON THE INTERNET WILL SHOW MANY INDIVIDUALS COMPLAINING ABOUT THE ISSUE. BUT GMC'S ADMISSION THAT THEY ARE "AWARE" BUT ARE TAKING NO ACTION AT THIS POINT IS VERY DISTURBING. I WOULD HAVE THOUGHT THAT DESIGN ISSUES WOULD HAVE HAD TO BE CLEARED BY AN OVERSIGHT AGENCY OF SOME SORT? I JUST DISCOVERED THE EXTREMELY SCARY FEELING OF "DRIVING IN THE DARK" ... BASICALLY ... AFTER HAVING MY TRUCK SINCE THANKSGIVING. BUT I DRIVE MOSTLY IN THE DAYLIGHT, AND HAVE BEEN ON INTERSTATE 20 IN ONE OF THE BUSIEST SECTIONS WITH TRAFFIC AT NIGHT ... NOT REALIZING HOW MUCH OTHERS' LIGHTS WERE HELPING. WHEN DRIVING ALONE ON A RURAL ROAD, HOWEVER, IT IS TANTAMOUNT TO DRIVING WITH A FLASHLIGHT WHEN IT COMES TO SAFETY. I AM WANTING TO TRUST THAT THE AGENCY TASKED WITH SAFETY WILL PLEASE LOOK INTO THIS ISSUE? BEFORE SOMEONE OR MULTIPLES LOSE THEIR LIVES AND LAWSUITS ENSUE? *TR

EXTERIOR LIGHTING
THE HEAD LIGHTS ON THIS TRUCK ARE OF POOR DESIGN AND ARE VERY WEAK. THE LIGHTS DO NOT ADEQUATELY LIGHT THE ROAD AHEAD OR THE SHOULDERS. THEY WILL BECOME A CONTRIBUTING FACTOR IN CRASHES AND DEATHS UNLESS THEY ARE IMPROVED! I CAN'T BELIEVE THESE HEADLIGHTS WOULD PASS THE MINIMUM STANDARDS FOR ILLUMINATION IF FOLLOW UP TESTING IS DONE IN POOR WEATHER CONDITIONS. *TR

FUEL/PROPULSION SYSTEM, ENGINE
PULLING OUT OF A SNOW COVERED PARKING LOT THE ENGINE LIGHT CAME ON DIC THEN THE MESSAGE, REDUCED ENGINE POWER, THE ENGINE BEGAN TO RUN VERY ROUGH AT A LOWER IDLE SPEED, AS BEGAN TO HAPPEN THE TRUCK LURCHED FORWARD AND I HAD TO PRESS HARD ON THE BRAKES VERY HARD LIKE I WAS FIGHTING THE ENGINE SPEED TO SLOW, THEN THE MESSAGE CHANGED TO SERVICE TRACTION CONTROL, I HAD NO CONTROL OVER THE GAS PEDAL AND COULD ONLY MOVE AT ABOUT 5MPH, THEN THE MESSAGE CHANGED TO SERVICE STABILITRAK, I GOT TO ANOTHER AREA OF THE PARKING LOT, PARKED AND SHUT OFF THE ENGINE FOR A FEW MINUTES AND THE ISSUE WOULD NOT GO AWAY. I WAS MORE THAN TWO HOURS FROM MY HOME. I REMOVED THE RED BATTERY CABLE THEN REPLACED IT AND WAS ABLE TO START THE ENGINE AND IT OPERATED NORMALLY FOR A WHILE. ONE AND A HALF HOURS LATER WHILE DRIVING 60MPH IT HAPPENED AGAIN AND I COST OFF THE INTERSTATE AND COULD NOT GET IT RUNNING AGAIN. HAD TO BE TOWED TO A DEALERSHIP. THEY SAID THERE WAS A SERVICE BULLETIN TO REPLACE THE THROTTLE BODY BUT WANT TO CHARGE ME $215 TO CLEAN THE OTHER FUEL RELATED PARTS. THIS NEEDS TO BE A RECALL. IF IT WAS A RECALL I WOULD NOT HAVE TO PAY $215 TO COMPLETE THE WORK PROPERLY. *TR
