ENGINE AND ENGINE COOLING:ENGINE
CHECK ENGINE LIGHT COMES ON AND ENGINES GOES INTO REDUCED POWER MODE. DOESN'T HAVE ENOUGH POWER TO GO OVER 40 MPH. WHILE PULLING A TRAILER THE ENGINE DOESN'T HAVE ENOUGH POWER TO CLIMB HILLS OR GO OVER 25 MPH. I HAVE TAKEN TO DEALER TWICE AND THEY SAY GM IS AWARE OF THE PROBLEM BUT THEY DON'T HAVE A FIX FOR IT. IT'S NOT SAFE HAVING A VEHICLE THAT BREAKS DOWN IN -15 DEGREE WEATHER AND HAVING THE DEALER TELL YOU THAT THERE IS NO FIX FOR THE PROBLEM AND TO JUST KEEP DRIVING THE VEHICLE. *TR

ELECTRICAL SYSTEM
I HAVE A 2007 SIERRA,WHICH HAS BEEN GIVING ME PROBLEMS SINCE IT WAS PUR CHASED. IT HAS STOP IN THE MIDDLE OF THE TRAFFIC WHEN I WAS DRIVING. IT HAS DONE THIS 4 TIMES SINCE I PURCHASED THE VEHICLE. I HAVE TAKING THE VEHICLE TO THE DEALER, BUT, THEY NEVER FIND ANYTHING WRONG. ON SATURDAY THE CAR STOP , IN THE MIDDLE OF TRAFFIC, AND THIS TIME IT DID NOT MOVE AT ALL. THE TRUCK WOULD NOT MOVE, AND I WAS TRYING TO MAKE A RIGHT, BUT I WAS STUCK. I WAS WORRIED THAT SOMEONE COULD CRUSH FROM THE BACK, BECAUSE THEY COULD NOT PASS, THERE WAS A MAN THAT CAME AND PUSH MY TRUCK TO GET OUT OF THE STREET .AND NOW I AM CONCERNED FOR THE SAFETY OF MY DAUGHTER AND ME. THIS VEHICLE HAS GIVING ME MANY PROBLEMS, BUT THE DEALER NEVER SEEMS TO FIND ANYTHING WRONG WITH THE VEHICLE. I HAD SOME ITEMS INSTALLED BY THEM. ONE WAS A DVD PLAYER, IT COST 2,300. AND THEY SAID THAT IT WAS MY FAULT SO THEY DID NOT FIX IT. AND THAT WAS 3 MOTHS AFTER THE INSTALLATION OF THE DVD BY THEM. AND THE BATTERY DIE ON THE TRUCK 4 MONTHS AFTER IT WAS PURCHASED. THAT WAS THE ONLY THING THEY CHANGE. I HOPE THAT I CAN BE HELPED, I FEEL VERY INSECURE IN THIS VEHICLE. I'M HAPPY THAT I DID NOT GET INTO A MAJOR ACCIDENT BECAUSE OF ALL THESE PROBLEMS. THANK YOU . *TR

SERVICE BRAKES, ELECTRIC
I WAS PULLED OVER BY MY LOCAL POLICE DEPARTMENT FOR DEFECTIVE BRAKE LAMPS 3 TIMES. I HAVE GONE TO MY LOCAL CHEVY DEALERSHIPS AND THEY REPLACE THE SWITCHES 4 TIMES. I THEN GOT PULLED OVER AGAIN SO I BROUGHT IT TO LEMAY BUICK AND GMC IN KENOSHA WI. THEY REPLACED THE BRAKE LAMP SWITCH 2 TIMES. WHEN YOU PUSH ON THE PEDDLE AND LET UP JUST A HAIR THE BRAKE LIGHT GO INOP. THIS IS A MAJOR CONCERN FOR ME BECAUSE I COULD GET REAR ENDED AT ANYTIME WITH NO BRAKE LIGHTS. I HOOKED UP A LIGHT ON MY DASH TO LET ME KNOW WHEN THEY ARE OR ARE NOT WORKING AT HIGHWAY SPEEDS THE LIGHTS DO NOT WORK 95% OF THE TIME GOING 70MPH AND SLOWING DOWN TO 55MPH THE LIGHTS DON'T EVEN BLINK. I TRIED CALLING GMC AND THEY SAID THERE IS NOT A PROBLEM WITH THE LIGHTS ON THESE VEHICLES. *TR

ELECTRICAL SYSTEM
TL*THE CONTACT OWNS A 2007 GMC SIERRA 1500. WHILE DRIVING 80 MPH IN THE RAIN, THE CIRCUIT BREAKER BOX FELL OFF THE VEHICLE AND LANDED BEHIND THE BRAKE PEDAL. THE CONTACT HAD TO STOP THE VEHICLE WITH THE EMERGENCY BRAKE. HE FEELS THAT THIS IS A SAFETY ISSUE BECAUSE COMPONENTS OF THE DASHBOARD SHOULD BE MORE SECURELY ATTACHED TO THE VEHICLE. HE ALSO FEELS THAT A SERIOUS CRASH COULD HAVE OCCURRED WITH THE CIRCUIT BOX TOP FALLING BEHIND THE BRAKE AND FIREWALL. THE CURRENT AND FAILURE MILEAGES WERE 1,700.

SERVICE BRAKES, HYDRAULIC, EXTERIOR LIGHTING
THE BRAKE LIGHTS TURN OFF IF YOU PRESS THE BRAKE AND THEN SLIGHTLY DEPRESS THE PEDAL, ALTHOUGH THE BRAKES ARE STILL APPLIED THE BRAKE LIGHTS ARE NOT ON. I FIRST NOTICED IT WHILE BACKING OUT OF A DRIVEWAY AT NIGHT, AND I DID NOT THINK IT WAS A SAFETY CONCERN UNTIL I SAW MY WIFE STOP FROM 45 MPH AND THE BRAKE LIGHTS FLASHED AND THEN TURNED OFF UNTIL SHE CAME TO A COMPLETE STOP. I TOOK THE TRUCK TO THE DEALERSHIP THEY THOUGHT THERE WAS A PROBLEM WITH THE TRUCK, AND REPLACED THE BRAKE LIGHT SWITCH. THE PROBLEM DID NOT GO AWAY. THE SAME DEFECT IS ON EVERY TRUCK ON THE CAR LOT. THE DEALERSHIP WROTE ON MY INVOICE THAT THE OWNER PRESUMES THAT WHEN THE BRAKE PEDAL IS PRESSED THE BRAKE LIGHTS SHOULD BE ON. DUH!! *TR

TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS
TIRE PRESSURE RECOMMENDED TOO HIGH. I BOUGHT A NEW 2007 GMC SIERRA 2500HD DIESEL CREW CAB LONG BED. AND THE REQUIRED TIRE PRESSURE FRONT IS 60PSI. THE REQUIRED REAR IS 80 PSI. COLD. THE DIAGNOSTICS ON DASH WARN YOU WHEN THE PRESSURE IS HIGH OR LOW BY 2LBS. THE PART THAT BOTHERS ME IS I PRIMARILY DRIVE THE TRUCK EMPTY AND IT IS VERY SQUIRRELLY AND HARD RIDING WHEN EMPTY AND TIRES AT 80 PSI. ESPECIALLY IN WET WEATHER. THE OTHER THING THAT BOTHERS ME IS THE TIRES ARE SIZE 245 75 R 16 E DESIGNED FOR NO MORE THAN 80 PSI COLD. THERE IS NO ROOM TO ALLOW LOWERING TIRE TO A SAFE PRESSURE WHEN TRUCK IS EMPTY. THE ONLY OTHER SOLUTION IS TO ADD WEIGHT TO THE BED OF THE TRUCK TO PUT TRACTION TO REAR TIRES AND I DON'T THINK THAT IS REALISTIC. BEFORE SOMEONE HAS AN ACCIDENT TRYING TO OBEY THE LABEL MAYBE THIS LABEL AND DIAGNOSTICS SHOULD BE CHANGED. *TR

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP
2007 GMC SIERRA CREW (NEW BODY STYLE) WHILE STOPPED AT A STOP SIGN I NEARLY HAD A VEHICLE REAR END ME. I HAD MY BRAKES DEPRESSED AND NOTICED MY BRAKE LIGHTS WERE NOT LIGHT UP. I THEN PRESSED A LITTLE HARDER ON THE PEDAL AND THEN MY LIGHTS CAME ON. THIS NEW BRAKE LIGHT WHERE IF YOU STEP AS HARD AS YOU WANT ON THE BRAKE AND THEN LET OFF A MICRO INCH AND IT GOES OFF. SO I GOT HOME AND DID SOME SEARCHING AND FOUND THAT THIS TYPE OF PROBLEM IS OCCURRING QUITE A LOT WITH THIS TRUCK MY THOUGHT ON THIS IS THAT ANY TIME THE T BRAKE PEDAL IS EVEN DEPRESSED JUST A LITTLE BIT THE LIGHTS SHOULD GO ON. I DID ALSO FIND IT STRANGE THAT THE BRAKE LIGHTS DO NOT WORK WITH THE IGNITION OFF. FIRST VEHICLE I CAN RECOLLECT EVER SET UP THAT WAY. *TR
