IN (ALWAYS AND ONLY) VERY COLD WEATHER WARNING MESSAGES APPEAR ON THE DASHBOARD WARNING OF TRACTION CONTROL/ABS FAILURE. ON A SNOW COVERED ROAD THE REAR AXEL SENT POWER TO THE WHEEL WITH THE LEAST TRACTION AND THE TRUCK STARTED SLIDING BACKWARDS. ABS BRAKES FAIL TO WORK AS ANTI-LOCK. THIS FAILURE OCCURS WHENEVER THE TEMPERATURE IS BELOW 25 DEGREES. THE FAILURE OCCURS AT ANY SPEED AND IS PRECEDED WITH DIFFICULTY SHIFTING OUT OF PARK. NOTE: I DID A GOOGLE SEARCH ON THIS ISSUE AND FOUND IT HAS BEEN OCCURRING FOR SEVERAL YEARS ACROSS GENERAL MOTORS BRAND VEHICLES. *TR

SINCE ABOUT 16,000 MILES, MY REAR BREAKS HAVE BEEN SQUEAKING. THE CHEVY DEALER HAS CLEANED THE BREAKS TWICE NOW AND IT HAS RESOLED THE PROBLEM FOR A FEW MONTHS, BUT HAS ALWAYS RETURNED. EACH TIME THEY CLEANED THE REAR DRUM BREAKS, THEY STATED THERE WAS EXCESSIVE BREAK DUST. THERE CLEARLY IS AN ISSUE WITH THIS YEAR MODEL AND THE REAR DRUM BREAKS. *JS

DRIVING ABOUT 60 MPH ABOUT 10 MILES INTO THE TRIP WHEN THE TRUCK LOST SPEED, THE ABS BRAKES DID A SLIGHT ON AND OFF PULSATING EVERY COUPLE OF SECONDS, THE ENGINE WAS RUNNING ROUGH AND GIVING IT GAS THE ENGINE REVVED UP BUT WOULDN'T GO ANYWHERE. SPEED DROPPED DOWN TO 35 OR 40 MPH AND WOULDN'T GO ANY FASTER. THE DASH INDICATOR SHOWED MESSAGES STATING STABILITRAK TRACTION CONTROL TURNED OFF AND CHECK ENGINE LIGHT IS ON. IT JOLTED REAL HARD WHEN IT SHIFTS GEARS. WHEN I MASHED THE BRAKE IT DIDN'T WANT TO COME TO A COMPLETE STOP WITHOUT PRESSING THE BRAKES TO HOLD THE TRUCK THERE. I PULLED INTO A STORE POPPED THE HOOD AND FINDING NOTHING I TURNED THE TRUCK OFF FOR A FEW SECONDS AND RESTARTED IT BUT NOTHING CHANGED AND THE ERROR MESSAGES WERE STILL BEING DISPLAYED. THE TRUCKS ENGINE WAS RUNNING ROUGH. I HEADED HOME AND IT DIDN'T HAVE ANY POWER AND JOLTED HARD AS IT SHIFTED GEARS. I COUDLN'T GO BUT 35 OR 40 MPH ON THE LEVEL GROUND. IF I WENT UP A SLIGHT HILL THE TRUCK SLOWED DOWN MORE UNTIL I GOT PAST THE HILL. I GAVE IT GAS AND THE ENGINE WOULD REV UP BUT HAD NO POWER AND WOULDN'T GO 35 OR 40 MPH. I PARKED THE TRUCK IN THE GARAGE AND IN 10 MINUTES I WENT TO START IT TO GET THE ERROR MESSAGES AND IT STARTED UP FINE AND THE ENGINE WASN'T RUNNING ROUGH. I DROVE IT 1/2 MILE DOWN THE ROAD AND BACK AND IT RAN PERFECT. I GOOGLED THE ERROR MESSAGES AND FOUND ALOT OF COMPLAINTS AND COMMENTS ABOUT THIS ISSUE ON THE CHEVROLET FORUM WEBSITE. NO RECALL INFORMATION JUST ALOT OF PEOPLE EXPERIENCING THE SAME ISSUE AND ALOT WORSE CASES THAT ALMOST CAUSED ACCIDENTS. IS THERE A RECALL ON THIS ISSUE? I READ THAT I WILL PROBABLY HAVE THE ISSUE AGAIN BECAUSE AFTER IT SITS FOR 10 MIN IT PROBABLY WON'T HAVE A PROBLEM UNTIL A FEW MINUTES OR DAYS LATER. I CAN ONLY HOPE DOESN'T CAUSE ME TO HAVE A WRECK AND KILL MYSELF OR SOMEONE ELSE. THIS IS A MAJOR ISSUE AND SHOULD BE RECALLED TO FIX THE PROBLEM. *TR

I HAVE A 2011 CHEVY SILVERADO WITH A FUEL GAUGE PROBLEM. WHILE DRIVING DOWNHILL, MY FUEL GAUGE LIGHT JUST COMES ON AND THE FUEL GAUGE GOES DOWN TO EMPTY. THE VEHICLE THEN STALLS LOSING ALL POWER AND CONTROL OF THE VEHICLE (BRAKES, STEERING). AS I REACH THE BOTTOM OF THE HILL, I HAVE TO PLACE THE VEHICLE IN PARK AND IT STARTS RIGHT BACK UP BUT THE FUEL GAUGE STAYS AT EMPTY. I HAD THE VEHICLE SERVICED AT A GM DEALERSHIP AND IT WAS STATED BY THE TECH THAT VEHICLE IS WORKING AS DESIGNED. THIS WAS ALSO CONFIRMED BY GM ENGINEERING DEPARTMENT. IF I RECALL, THE FUEL PUMP IS PLACED MORE TOWARD THE BACK OF TRUCK AND WHILE DRIVING DOWNHILL GAS MOVES TOWARDS FRONT OF TANK GIVING THE FUEL SENSOR A FALSE READING. I'M NO ENGINEER BUT I HAD A 2009 SILVERADO AND NEVER CAME ACROSS THIS PROBLEM. THIS IS A BIG VEHICLE AND I BELIEVE THIS POSES A GREAT SAFETY RISK TO MYSELF AND FAMILY AS WELL AS THE PUBLIC. MANY TIMES WHEN THE TRUCK HAS LOST ALL POWER STEERING AND BRAKING CAPABILITY, MYSELF OR MY FAMILY MEMBERS WHO ARE DRIVING HAVE NARROWLY AVOIDED ACCIDENTS. GM TECH AND GM CORPORATE SAID REMEDY IS TO KEEP MORE GAS IN VEHICLE. THIS IS A CONTINUOUS PROBLEM AS AT TIMES IN TRAVEL I MAY NOT KEEP MY TANK AS FULL AS REQUIRED BY GM.
