ELECTRICAL SYSTEM, ENGINE
2006 GMC SIERRA QUIT RUNNING ON A TRIP WE WERE TAKING. IT STARTED MISSING AND EVENTUALLY WOULDN'T RESTART. THE TRUCK HAS 82K ON IT AND IS VERY WELL MAINTAINED. THE ENGINE WOULD TURN OVER BUT NOT START... NO SPARK? IT HAS BEEN TO VARIOUS SERVICE MECHANICS AS WELL AS MY ATTEMPT TO FIGURE OUT WHAT IS WRONG WITH IT. MANY NEW PARTS HAVE BEEN USED: ICM, CRANK SENSOR, CAM SENSOR, COIL... NO DIFFERENCE. THIS VEHICLE QUITTING ON A VERY BUSY HIGHWAY COULD HAVE CAUSED SIGNIFICANT INJURY TO MYSELF AND/OR MY PASSENGER. WHEN THE TRUCK WAS NEW IT HAD AN INTERMITTENT MISS AND WHILE STILL UNDER WARRANTY I RETURNED TO THE DEALER. THERE THEY WERE UNABLE TO FIND ANYTHING THAT WOULD CAUSE THE PROBLEM. THIS SAME MISS WAS PERIODICALLY PRESENT UP UNTIL THE TIME IT QUIT RUNNING ALTOGETHER.

STRUCTURE:BODY
DASHBOARD CRACK ABOVE STEERING COLUMN AND ABOVE PASSENGER SIDE AIRBAG. THIS ISSUE POSES SAFETY CONCERNS REGARDING WHETHER THE AIRBAG WILL BE PUNCTURED OR OTHERWISE INEFFECTIVE DURING DEPLOYMENT DUE TO THE SHARP CRACKED EDGES OF THE DASH AS WELL AS THE POTENTIAL FOR SHARDS OF CRACKED DASH BECOMING PROJECTILES CAUSING INJURY TO OCCUPANTS DURING A COLLISION. NOTHING HAPPENED TO THE VEHICLE. WE WERE DRIVING DOWN THE FREEWAY AND NOTICED THE CRACK. THE CRACKS BECOME LARGER EVERYDAY.

SERVICE BRAKES
PULLING TO A STOP IN MY DRIVEWAY MY BRAKES SLOWED THE TRUCK AND THEN COMPLETELY GAVE WAY WITH THE PEDAL HITTING THE FLOOR. I STOMPED ON THE EMERGENCY BRAKE PEDAL TO KEEP FROM HITTING THE PORCH. I AM SO LUCKY TO HAVE THAT HAPPEN AT LOW SPEED OFF THE ROAD. THAT COULD HAVE BEEN A TRAGEDY ON THE HIGHWAY. TURNS OUT THAT MY BRAKE LINES ARE SEVERELY RUSTED AND ONE OF THE 2 LINES COMING OFF THE MASTER CYLINDER NOW HAS A PINHOLE LEAK IMMEDIATELY ABOVE THE FRAME WHERE IT BENDS 90 DEGREES TO GO BACK TO THE ABS MANIFOLD. APPLYING THE BRAKES JUST SQUIRTS FLUID OUT OF THE LINE. I THOUGHT A SINGLE FAILURE WAS SUPPOSED TO RESULT IN REDUCED BRAKING POWER, NOT COMPLETE LOSS OF BRAKES. NOTE THAT MY TRUCK IS IN OTHERWISE GREAT SHAPE AND I SIMPLY HAD NO IDEA. IT IS CLEAR THAT THE NHTSA HAS BEEN BAMBOOZLED BY GM. BRAKE LINES ARE A CRITICAL LIFE SAFETY SYSTEM, INSTALLED ON AND IN SOME PLACES IN THE CHASSIS BEFORE THE VEHICLE BODY AND BED ARE ATTACHED. IT IS NOT ROUTINE MAINTENANCE TO RINSE THE BRAKE LINES LET ALONE REPLACE THEM. GM PUSHING THIS BACK ON THE CUSTOMER IS COMPLETE BS. YOU CAN BUY NYLON COATED OR STAINLESS STEEL BRAKE LINES FOR LESS THAN 100 $. THE INCREMENTAL COST TO GO FROM STEEL TO SOMETHING THAT WOULD LAST THE OPERATIONAL LIFE OF THE VEHICLE IS LESS THAN 50 $. I'M WAITING ON AN ESTIMATE FROM MY NON-DEALER SHOP, BUT A DEALER CHARGING 3600 $ IS NOT SURPRISING CONSIDERING THE AMOUNT OF LABOR THAT MUST BE INVOLVED. THE NHTSA DECISION ON THE ISSUE IS UNCONSCIONABLE. GUESS IT MIGHT HAVE BEEN DIFFERENT IF THEY HAD RUN OVER A CHILD AT A CROSSWALK OR IF THEIR CHILD WAS MOWED DOWN BY CORPORATE GREED. HOPEFULLY THAT NEVER HAPPENS, BUT WITH SO MANY ROTTING GM TRUCKS ON THE ROAD, WE WILL HAVE TO KEEP OUR FINGERS CROSSED.

UNKNOWN OR OTHER
NO ACCIDENT HAS OCCURRED YET AS A RESULT OF THE FOLLOWING DEFICIENCY. HEADLIGHTS ON MY 2014 GMC SIERRA 1500 SLT ARE TOTALLY INADEQUATE ON HIGH OR LOW BEAM. THE LIGHTING DISTANCE IS INADEQUATE AND IS SO DIRECTIONAL THAT THERE IS NO SIDE FLAIR LIGHTING FOR TURNING LIKE YOU HAVE WITH CONVENTIONAL HEADLIGHTS. THIS IS A SERIOUS SAFETY ISSUE AND NEEDS TO BE ADDRESSED IMMEDIATELY BY THE NHTSA. I HAVE HAD THIS VEHICLE FOR 1 1/2 YEARS AND THE PROBLEM IS ONGOING SINCE I BOUGHT IT. THE DEALER HAS NO SOLUTION.

SERVICE BRAKES
I WAS ON MY WAY HOME RUNNING 45 MPH IN LIGHT TRAFFIC. WHEN I WENT TO MAKE A LEFT HAND TURN AND MY BRAKE PEDAL WENT TO THE FLOOR. SCARED THE HELL OUT OF ME. I WAS ABLE TO PUMP THEM ENOUGH TO MAKE THE TURN AND LUCKILY I WAS ONLY THREE BLOCKS FROM MY HOME. I WAS ABLE TO COAST IT HOME. I RAISED THE HOOD AND ALL THE BRAKE LINES ARE SO RUSTY. I HAD MY WIFE STEP ON THE BRAKE AND YOU CAN SEE ONE LINE BUSTED. I CHECKED WITH DEALER AND THEY DON'T OFFER REPLACEMENT PARTS. YOU HAVE PAY SOMEONE TO MAKE THE LINES FOR YOU.

ELECTRICAL SYSTEM
THE INFOTAINMENT SCREEN IS VERY DISTRACTING WHEN DRIVING AT NIGHT. REGARDLESS OF THE SYSTEM DISPLAYED, (RADIO, PHONE, OR JUST THE CLOCK/OFF SCREEN), THE LIGHTING IS TOO BRIGHT. THIS IS EXTREMELY DISTRACTING TO THE DRIVER. THE DASH LIGHT DIMMER CONTROL SWITCH WORKS THE DASH LIGHTS AND THE INFOTAINMENT SCREEN. IF ONE WERE TO DIM THE DASH LIGHTS SO THAT THE INFOTAINMENT LIGHT IS LOW ENOUGH TO BE ACCEPTABLE, THEN THE DASH LIGHTS ARE TOO LOW TO BE EFFECTIVE AND USED. THE INFOTAINMENT SCREEN SHOULD HAVE A SEPARATE REMOTE SWITCH KNOB TO CONTROL JUST THE INFOTAINMENT SCREEN. I CONTACTED THE GMC CUSTOMER SERVICE #, AND THEY CONFIRMED THAT THIS IS THE WAY IT IS DESIGNED, AND COULD NOT BE ALTERED OR ADJUSTED. CLARIFICATION ON THE DATE OF INCIDENT AND MILEAGE ABOVE, AS THIS HAS OCCUERED SINCE DAY OF PURCHASE.

SERVICE BRAKES
TURNING INTO AN AUTO PARTS STORE, FROM THE HIGHWAY, WHEN I APPLIED THE BRAKES THE PEDAL WENT CLEAR TO THE FLOOR. MY TRUCK SLOWED BUT NOT ENOUGH IF ANYONE WALKING OR A CAR HAD BEEN THERE I WOULD HAVE HIT THEM. I WAS VERY LUCKY. OF THE FOUR BRAKE LINES ONE BURST, TWO WERE SEEPING, BUT NOT DRIPPING AND THE REAR LINE WAS ALMOST AS BAD AS THE OTHER LINES AND ITS A WONDER IT DIDN'T BREAK AT THE SAME TIME. GOING HOME I WOULD HAVE GONE DOWN A VERY STEEP HILL WITH A STOPLIGHT AND A VERY BUSY INTERSECTION. IT COULD HAVE BEEN A DISASTER. THIS IS A LOW MILEAGE TRUCK, SELDOM DRIVEN IN SNOW.

VEHICLE WAS STOPPED. BRAKE PEDDLE WENT TO THE FLOORBOARD. NOT ABLE TO PUMP UP ANY PRESSURE. INVESTIGATION SHOWED BRAKE FLUID COMING FROM PERFORATED BRAKE LINE AT LEFT FRONT WHEEL. NO BRAKING ACTION AVAILABLE! APPEARS TO BE SOME TYPE OF CORROSIVE REACTION BETWEEN THE BRAKE LINE AND THE CLAMPS USED TO FASTEN THE LINE TO THE CHASSIS. NOTE: THIS VEHICLE HAS NEVER BEEN OPERATED IN SNOW OR ROAD SALT TO MY KNOWLEDGE.
