The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by General Motors Corporation (GM).On July 2, 2010, ODI received GM's response to an information request, which included GM's assessment of the frequency and safety consequences of the alleged defect. GM stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of Federal Motor Vehicle Safety Standards 105 and 135, Light Vehicle Brake Systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (MIL) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure.ODI's and GM's analysis indicates that 85 percent of the complaints occurred on vehicles used primarily in States that use salt on the roads during Winter months (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin).Overall the complaint rates per 100,000 vehicles for Salt Belt States is 43.0 and Non-Salt Belt is 3.0.In approximately 25 percent of the complaints the brake pipe failure occurred suddenly, with no warning (i.e., no MIL, Brake Fluid Loss Warning), and resulted in extended stopping distances.In 30 of these the increase in stopping distance that resulted was a factor in the crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.This investigation has been upgraded to an Engineering Analysis (EA11-001) for subject vehicles sold or currently registered in Salt Belt States to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. ODI will continue to gather information on subject vehicles outside the Salt Belt as well.

ODI'S REVIEW OF COMPLAINT DATA RECEIVED SINCE THE CLOSE OF EA04-011 REVEALED NO INDICATION THAT THE INVESTIGATION SHOULD BE RE-OPENED.MORE DETAILS CAN BE FOUND IN THE FEDERAL REGISTER NOTICE ENCLOSED IN THE DP05-009 PUBLIC FILE.ODI RESERVES THE RIGHT TO REOPEN THE INVESTIGATION IN THE FUTURE SHOULD CONDITIONS WARRANT.

IN A LETTER DATED AUGUST 29, 2005, GM NOTIFIED ODI THAT IT WAS RECALLING CERTAIN MODEL YEAR 1999 THROUGH 2002 C/K PICKUP TRUCKS AND SPORT UTILITY VEHICLES TO CORRECT A PROBLEM WITH ANTI-LOCK BRAKE SYSTEM (ABS) WHEEL SPEED SENSOR CORROSION THAT MAY RESULT IN UNWANTED ABS ACTIVATION AND EXTENDED STOPPING DISTANCES DURING LOW-SPEED BRAKING (RECALL 05V-379).GM'S RECALL COVERS APPROXIMATELY 804,000 VEHICLES CURRENTLY REGISTERED IN THE FOLLOWING 14 SALT-BELT STATES:CONNECTICUT, ILLINOIS, INDIANA, MASSACHUSETTS, MAINE, MICHIGAN, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, AND WEST VIRGINIA.THE RECALL PROCEDURE WILL INVOLVE REMOVING THE SENSOR, CLEANING THE MOUNTING SURFACE, APPLYING A RUST INHIBITOR (ZINC-X) TO THE SURFACE, AND REINSTALLING THE SENSOR.IF NECESSARY, THE SENSOR WILL BE REPLACED. THE POPULATION AND FAILURE REPORT DATA GIVEN IN THIS RESUME ARE FOR THE FULL REGION THAT HAS BEEN CONSIDERED BY ODI AS THE SALT-BELT.THAT INCLUDES DELAWARE, IOWA, MARYLAND, MINNESOTA, MISSOURI, WISCONSIN AND THE DISTRICT OF COLUMBIA IN ADDITION TO THE 14 STATES INCLUDED IN 05V-379.THE STATES COVERED BY GM'S RECALL HAVE THE HIGHEST INCIDENT RATES FOR THE SUBJECT CONDITION, ACCOUNTING FOR 91% OF THE INCIDENTS, BUT ONLY 24% OF SUBJECT VEHICLE SALES IN THE UNITED STATES.ODI'S ANALYSIS DETERMINED THAT 840 OF THE COMPLAINTS, 244 OF THE CRASHES, AND 16 OF THE INJURIES IDENTIFIED IN THIS INVESTIGATION OCCURRED IN THOSE STATES.THE RESULTING INCIDENT AND CRASH RATES ARE 96.2 AND 28.0 PER 100,000 VEHICLES RESPECTIVELY (NOTE:RATES ARE BASED ON VEHICLE SALES, NOT REGISTERED VEHICLES). THE CORRESPONDING NUMBERS IN THE EXCLUDED PORTIONS OF THE SALT-BELT ARE 399,000 VEHICLES, 81 INCIDENTS (20.3 PER 100,000 VEHICLES), 3 CRASHES, AND NO INJURIES.THE STATISTICS IN THE REMAINING 30 STATES ARE 2,406,000 VEHICLES, 168 INCIDENTS (7.0 PER 100,000 VEHICLES), 31 CRASHES, AND ONE INJURY.GM AND ODI ARE CONTINUING TO MONITOR THE PROBLEM EXPERIENCE IN STATES THAT ARE NOT INCLUDED IN THE RECALL.GM WILL PROVIDE ODI WITH UPDATED COMPLAINT, FIELD REPORT, AND WARRANTY DATA IN NOVEMBER 2005.ODI AND GM WILL REVIEW THAT DATA AND ASSESS THE APPROPRIATENESS OF THE CURRENT SCOPE OF THE RECALL AT THAT TIME.

THE AUTOMATIC LOCKING RETRACTOR (ALR) IS A FEATURE INCORPORATED IN THE SUBJECT VEHICLE FOR LOCKING THE WEBBING TO PROPERLY SECURE A CHILD SAFETY SEAT INTO A VEHICLE.THIS PE WAS OPENED BASED ON A GM TECHNICAL SERVICE BULLETIN STATING THAT WITH CERTAIN CHILD SAFETY SEATS THE WEBBING MAY NOT REMAIN LOCKED.THERE ARE NO COMPLAINTS IN THE ODI DATABASE AND ONLY TWO COMPLAINTS TO GM.GM'S INSTRUCTIONS STATE FOR THE FINAL STEP IN USING THE WEBBING LOCK FEATURE TO PUSH AND PULL THE CHILD RESTRAINT TO BE SURE IT IS SECURE. IF THE ALR IS NOT LOCKED, THE USER WOULD BE FULLY AWARE OF THIS CONDITION PRIOR TO COMPLETING PROPER INSTALLATION OF THE CHILD SAFETY SEAT IN THIS VEHICLE.THIS INVESTIGATION DID NOT UNCOVER ANY COMPLAINTS OF THE ALR INADVERTENTLY UNLOCKING WHILE THE VEHICLE IS IN MOTION.THE EMERGENCY LOCKING RETRACTOR (ELR) FEATURE REMAINS AVAILABLE TO LOCK THE RETRACTOR IN A CRASH.A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.SEE ATTACHED SUMMARY FOR ADDITIONAL INFORMATION.

NO MATTER HOW MANY TIMES I GET MY BRAKES FIXED THERE IS ALWAYS THE BREAK AND THE AIR BRAKE LIGHTS THAT APPEAR. I HAVE CHANGED TO SENSORS, FUSES AND STILL IT REMAINS. EVERY MECHANIC TELLS ME THAT NO MATTER WHAT THE BRAKE AND AIR BRAKE LIGHTS WILL APPEAR. THAT NEEDS TO BE A RECALL. SEEING ANY TYPE OF WARNING LIGHTS DRIVES ME CRAZY IF THERE IS NOTHING WRONG WITH MY BRAKES THEN THERE SHOULD BE NO WARNINGS. *TR

ON 01/23/2018 I GOT INTO AN ACCIDENT. THE BRAKES WHEN APPLIED HESITATED FOR A FEW THEN FINALLY TOOK HOLD BUT BY THAT TIME IT WAS TO LATE AND I ENDED UP ON SOMEONES LAWN AFTER CRASHING THROUGH THEIR WHITE PICKET FENCE, THEN ROLLING COMPLETELY OVER ON ITS TOP, TOTALLY THE YUKON. MY CONCERN IS THE NO AIRBAGS DEPLOYED AT ALL. THANKFULLY, I ONLY RECEIVED MINOR SCRAPES AND BRUISES. PLUS, I AM VERY SORE STILL. I AM CONCERNED THAT THIS COULD OF BEEN A WORSE CASE, WHERE I GOT SERIOUSLY INJURED OR EVEN DEATH BECAUSE THE AIRBAGS DID NOT DEPLOY UPON IMPACT. I HAVE NOTIFIED MY INSURANCE COMPANY TO MAKE SURE THERE IS A WRITTEN PAPER TRAIL PERTAINING TO THESE ISSUES WITH THE YUKON. SPECIFICALLY, THE BRAKES NOT CATCHING IN TIME AND THE AIRBAGS NOT DEPLOYING. I WOULD APPRECIATE A RESPONSE BACK TO THIS MATTER AS SOON AS YOU CAN. I ALSO BELIEVE THAT THE ACCIDENT MIGHT NOT OF RESULTED IN TOTALING MY VEHICLE IF THE BRAKES WERE WORKING PROPERLY. WHEN I APPLIED BRAKES IT FELT LIKE THEY WERE CATCHING BUT SEEMED TO TAKE FOREVER TO STOP SOON ENOUGH, ALMOST A HESITATION ON THE BRAKES PART. PLUS, THE AIRBAGS DID NOT WORK EITHER. SO I NEED TO KNOW WHERE I CAN FILE A CLAIM PERTAINING TO TOTALING MY VEHICLE BECAUSE OF FAULTY BRAKES AND AIRBAGS NOT DEPLOYING. THIS COULD OF BEEN A WORSE CASE! THANK YOU

This PI communicates the requirement to provide a pico file to receive diagnostic assistance from TAC.

This Preliminary Information communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester  and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.

This Preliminary Information communication provides information to the technician about vehicles that the Heater-Vent-Air Conditioning blows warm air. Before calling General Motors Technical Assistance Center technician will need to have high and low pressures, outside temperature, humidity, and vent temperature.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.
