I WAS TRAVELING IN RULE AREA OF MICH. AFTER DARK,A DEER JUMP OUT IN FRONT OF ME! I HIT THE BRAKES,A BRIEF BRAKE SURGE, THEN THE PEDAL WENT TO THE FLOOR! NO BRAKES! THE BRAKE LINES UNDER THE DRIVERS SEAT AREA WERE RUSTED THROUGH! I STOP AT A GAS STATION. I FOUND BRAKE FLUID ALL OVER AND A MAN ASKED ME WHAT HAD HAPPENED,I TOLD HIM WHAT I FOUND , HE AND I COULDN'T BELIEVE THEY WERE SO RUSTED OUT ! MY TRUCK IS IN VERY GOOD SHAPE! EXCEPT FOR THE BRAKE LINES! IT'S GOT A STAINLESS STEEL EXHAUST SYSTEM BUT THEY SCRIMP ON ONE OF THE MOST CRITICAL SYSTEMS FOR SAFETY ! UNBELIEVABLE! BY THE GRACE OF GOD I DIDN'T HIT THE DEER! BUT WHAT IF IT HAD HAPPENED IN TOWN OR IF THE DEER WAS A CHILD! THANK GOD IT HAPPENED THE WAY IT DID AND NO ONE GOT HURT! *TR

THE DASH IS MY TRUCK HAS STARTED TO CRACK. FROM RESEARCH ON THE INTERNET I SEE THIS IS A FAIRLY COMMON OCCURRENCE. THE DEALER SAID IT IS NOT COVERED ALTHOUGH I HAVE AN EXTENDED WARRANTY. I AM UNSATISFIED WITH GM AND FEEL THIS CRACK DASH COULD BE A HAZARD IF AN ACCIDENT WERE TO OCCUR. I WOULD LOVE A COMPROMISE FROM GM TO AT LEAST OFFER TO PAY SOME OF THE COST OF REPLACEMENT, IF NOT ALL OF IT. *TR

ELECTRICAL SYSTEM
I' M WRITING IN TOO COMPLAIN ABOUT THE DASHBOARD CLUSTER ON MY 2009 GMC SIERRA. I SEE THAT A RECALL ALONG WITH A LAWSUIT WITH THIS SAME ISSUE WAS SUBMITTED. I HAVE BEEN GOING BACK AND FORTH WITH GMC ON THIS ISSUE SINCE 2011. THEY STATED IT WAS A FUSE AND REPLACED THE FUSE , BUT MY DASHBOARD ALONG WITH ALL THE GAUGES GO OUT EVERY COUPLE OF MONTHS. I WAS TOLD THEY DIDN'T KNOW WHAT THE PROBLEM WAS BUT OBVIOUSLY THEY DID. THIS ISSUE WAS NOTED AFTER A CLASS ACTION LAWSUIT WAS FILED. THIS IS A VERY EXPENSIVE FIX THAT SHOULD HAVE BEEN TAKEN CARE OF WHEN IT FIRST HAPPENED IN 2011. THE LAST TIME MY DASHBOARD WENT OUT (WHILE DRIVING) WAS 10/14/2014. *TR

EXTERIOR LIGHTING
POOR LIGHTING WITH HEADLIGHTS. CAN BARELY SEE WHAT IS AHEAD AT NIGHT. SEEMS LIKE THIS COULD BE VERY DANGEROUS, AND I FEEL UNSAFE DRIVING AT NIGHT, ESPECIALLY IN THE RAIN. TURNING ON FOG LIGHTS HELPS A LITTLE, BUT YOU SHOULDN'T HAVE TO CONSTANTLY RUN THEM. BRIGHT LIGHTS DON'T HELP MUCH EITHER. *TR

EXTERIOR LIGHTING
BOUGHT VEHICLE NEW IN MARCH '14, HEADLIGHTS ARE HID UNITS, AND ARE WORSE THAN POOR. VERY EASY TO OVERDRIVE THESE LIGHTS HERE ON DARK, TWISTY MOUNTAIN ROADS IN WV. WE HAVE THE HIGHEST RATE OF VEHICLE- DEER COLLISIONS IN THE US AND SEEING DEER WITH THESE LIGHTS IN TIME TO AVOID A COLLISION IS CHANCY. TRADED A 10 YEAR OLD SAME MAKE AND MODEL AND NEVER HAD THESE PROBLEMS. THESE LIGHTS NEED TO BE CORRECTED BEFORE FOLKS ARE KILLED AS A RESULT. *TR

EXTERIOR LIGHTING
HEADLIGHTS ON 2014 SIERRA 1500 ARE HORRIBLE. DO NOT PROJECT VERY FAR DOWN THE ROAD AND THE BRIGHTS DO NOT DO ANYTHING BUT LIGHT UP THE TOPS OF TREES. AT DUSK, DAWN, OR WHEN RAINING IS PARTICULARLY BAD. ON MORE THAN ONE OCCASION DRIVING IN SMALL TOWNS OR IN TRAFFIC I THOUGHT THE LIGHTS WERE ACTUALLY OFF THEY ARE SO DIM. I TOOK IT TO THE DEALER SHORTLY AFTER I GOT THE TRUCK IN SEPTEMBER OF 2013 AND THEY SAID THEY ADJUSTED THEM BUT IT DIDN'T DO ANYTHING. I HAVE CONTINUED TO HAVE PROBLEMS AND IT SEEMS LIKE THEY ARE GETTING EVEN DIMMER NOW. VERY DISAPPOINTED...SOMEONE IS GOING TO HAVE A WRECK ONE OF THESE DAYS BECAUSE OF THESE AS YOU CANNOT SEE WHAT IS IN THE ROAD 100 FEET AHEAD. AT 55 MPH THAT COULD BE A DEATH SENTENCE. *TR

ELECTRICAL SYSTEM, AIR BAGS, EXTERIOR LIGHTING
I HAVE HAD TO REPLACE THE TAIL LIGHT LENSES SEVERAL TIMES BECAUSE THE TAB THAT SECURES THE LENSES TO THE VEHICLE BREAKS AND THE RESULT IS LIGHTS JUST HANGING ON THE TRUCK BY THE ELECTRICAL CORDS. I HAVE THE SAME PROBLEM INVOLVING MY OTHER VEHICLES IN THE PAST MADE BY GMC NAMELY A SECOND FAMILY GMC SIERRA THAT WAS MADE IN THE YEAR 2004, AND A CHEVROLET SILVERADO. THE ELECTRICAL LIGHTING ON THE DASHBOARD HAS BEEN MALFUNCTIONING FOR A LONG TIME. I NOTICED THE MALFUNCTION DURING THE FIRST YEAR I BOUGHT THE TRUCK. I HAVE HAD TO REPLACE ELECTRICAL SWITCH IN THE AIR CONDITIONING/HEATING THE MECHANIC TOLD ME THAT THE WIRING IS HEATING UP AND CAUSING THE SHORT TO THE SWITCH. THE NEW SWITCH HAS SHORTED OUT JUST LIKE HE SAID IT WOULD. I HAVE A NOTIFICATION THAT MY AIRBAG NEEDS SERVICING. THERE HAS BEEN NO ACCIDENT INVOLVED TO CAUSE THIS ISSUE. I BOUGHT THIS VEHICLE NEW AND HAVE BEEN THE PRIMARY DRIVER SINCE 2006 WHEN I BOUGHT THE VEHICLE. *TR

SERVICE BRAKES, WHEELS
I WAKE UP EARLY ON SUNDAY, ON 11/16/15 AND TOOK A COMPANY TRUCK A 2006 GMC SIERRA 1500, TO BRING SOME CARGO. ON MY WAY BACK HOME ON 836 WEST EXPRESSWAY, I TOOK MY EXIT AND WHEN PRESS THE BRAKE PEDAL TO REDUCE SPEED, THE PEDAL WENT TO THE FLOOR OF THE CAR AND THE BRAKE ACTION WAS MINIMUM TO NOTHING. ANOTHER VEHICLE WAS STOP AT THE TRAFFIC LIGHT, AND TO AVOID THE OBVIOUS IMPACT TO THE STOPPED CAR, I PUMPED THE BRAKES SEVERAL TIMES AND APPLIED THE PARKING BRAKES AT APPROX. 30 MPH. SEEING NO WAY TO AVOID THE COLLISION, I PULL THE CAR TO THE SIDE OF THE ROAD AND HIT A CONCRETE WATER DRAIN, RESULTING IN ABRUPTLY SOPPING OF MY CAR AND MY KNEE HIT THE LOWER DASHBOARD. THE GUY OF THE OTHER CAR WENT OUT AND ASK ME, ARE YOU "DRUNK" "ARE YOU OK" I CALLED A FLATBED AND BRING MY TRUCK TO MY WORK PLACE AND THEN NOTICE THAT A BRAKE LINE WAS BROKE AND MOST OF THE BRAKE FLUID SPILLED ALL OVER THE FRONT OF THE CHASSIS, UNDER THE RADIATOR. THE BRAKE LINE WAS INCREDIBLE RUSTED, REASON FOR THE BRAKE DOWN, I HAD CARS WITH A LOT MORE YEARS WITH NO PROBLEM WITH BRAKE LINES. WHEN I INSPECT THE OTHER BRAKE LINES DEEPLY, NOTICED THAT AN EXCESSIVE CORROSION WAS IN ALL OF THEM. GMC SHOULD DO SOMETHING ABOUT THIS, SAFETY ISSUE, IS NO REASON FOR A 2006, ONLY 8 YEARS VEHICLE, PRESENT THAT LEVEL OF CORROSION ON BRAKE LINES. "COKE CAN THICKNESS APPARENTLY" . SOMEBODY WILL DIE OR SERIOUSLY INJURE, OR WILL KILL SOMEBODY, PEDESTRIAN OR DRIVER BECAUSE THE SUDDEN BRAKE FAILURE IN A CASE LIKE THIS. I WILL BRING THE VEHICLE TO A GARAGE TO REPLACE THE BROKEN LINE AND PROBABLY ALL OF THEM.. ITS RIDICULOUS, AND VERY DANGEROUS THAT THIS THINGS HAPPENS IN A VEHICLE THAT AGE. I REALLY APPRECIATE TO BRING THIS CASE TO THE PROPER ATTENTION OF THE MANUFACTURER IN ORDER TO AVOID MORE INCIDENTS LIKE MINE.I CONSIDER MYSELF VERY LUCKY,.COULD NOT BE WRITING THIS IF THIS HAPPENS TO ME AT A HIGH SPEED.

NOV. 15, 2014: TURN KEY BUT, ELECTRICAL SYSTEM IS COMPLETELY DEAD. THEN, TAKE KEY OUT FOR FIVE MINUTES, PUT BACK IN, AND STARTS RIGHT UP LIKE NOTHING WRONG. *TR

3 OF MY 4 DOOR LOCK ACTUATORS HAVE FAILED. BOTH REAR DOORS COULD NOT BE LOCKED OR UNLOCKED EXCEPT MANUALLY FROM WITHIN THE VEHICLE. REACHING OVER THE SEAT TO UNLOCK A CHILD'S DOOR IN AN EMERGENCY CONSTITUTES A SAFETY HAZARD. IN MY OPINION, GMC SHOULD STEP UP AN ACKNOWLEDGE AND ADDRESS THIS ISSUE. *TR

ENGINE AND ENGINE COOLING
NEAR 69,150 MILES THE OIL PRESSURE GAUGE FOR MY GMC SIERRA 1500 2011, ALL AT ONCE, WENT TO ZERO GIVING ME A WARNING MESSAGE TO IMMEDIATELY STOP THE ENGINE. IT TURNED OUT TO BE A FAULTY OIL PRESSURE SENSOR. IN ADDITION OIL WAS LEAKING BADLY OUT AROUND THE SENSOR AND COMPLETELY COATED EVERYTHING IN THE ENGINE COMPARTMENT AND UNDERNEATH. A YEAR LATER THE SENSOR WENT BAD AGAIN. GMC SAYS ITS NOT COVERED UNDER THE POWER TRAIN WARRANTY AND ITS COSTING ME $400 EACH TIME IT GOES BAD. *TR
