FAILING FUEL INJECTORS CAUSING SMOKE OUT OF EXHAUST ON A DURAMAX DIESEL TRUCK. GM KNEW OF DEFECT WITH INJECTORS AND ONLY ISSUED AN EXTENDED WARRANTY FOR 7 YEARS/200,000 MILES WHICH EVER OCCURRED FIRST. IT WAS ONLY GOOD IF YOU HAD AN ISSUE WITH THE INJECTORS AT THE TIME OF WARRANTY. I JUST FOUND THIS OUT FROM A DEALER AND OTHER OWNERS OF SAME TYPE VEHICLE. IF GM KNOWINGLY KNEW OF THESE ISSUES WHY DID THEY NOT DO A RECALL ON SAID VEHICLES? IT'S REALLY A MATTER OF PRINCIPLE AND MORAL ETHICS TO DO THE RIGHT THING, RATHER THAN HAVE THE CONSUMER TAKE THE FALL FOR THEIR LACK OF PRODUCT DESIGN! *TR

I OWN A 2002 CHEVY SILVERADO 2500 HD 4X4. IN THE PAST COUPLE OF MONTHS MY ABS HAS BEEN ACTIVATING AT LOW SPEEDS FOR NO REASON (CONDITIONS DRY WITH NO WATER AND ICE). IT CAUSES ME TO SLOW EARLIER THAN NORMAL TO PREVENT STOPPING TOO LATE. I HAVE BEEN RESEARCHING THIS AND IT APPEARS THAT IT MAY BE COVERED BY A RECALL (PE05020). I LIVE IN MARYLAND AND AM NOT YET SURE IF MY STATE IS COVERED. I BOUGHT MY VEHICLE SECOND HAND FROM A CHEVY DEALER 6/29/04 AND HAVE NOT RECEIVED A RECALL NOTICE (I HAVE RECEIVED OTHERS IN THE PAST). FILING THIS AND CONTACTING MY DEALER IN CASE NHTSA THINKS MD SHOULD NOT BE COVERED. THE FAILURE OCCURS DAILY AND CAUSES LONGER STOPPING DISTANCE. *TR

I WANT TO ADD ANOTHER CASE TO YOUR INVESTIGATION OF BRAKE LINE FAILURES ON GM TRUCKS. I LIVE IN MARYLAND AND HAVE A 2002 CHEVY SILVERADO 2500HD WITH ONLY 40,000 MILES ON IT. MY BRAKE LINES RUSTED THROUGH IN THREE SEPARATE INCIDENTS THIS YEAR. FIRST, THE FRONT WHEEL SPEED SENSORS/ABS SYSTEM FAILED IN APRIL, 2010. NEXT, IN JULY, THE FRONT PART OF THE LINES GAVE WAY WHEN BEING BACKED OUT OF THE GARAGE AFTER GETTING AN OIL CHANGE. THAT GARAGE REPLACED THE FRONT PART OF THE BRAKE LINES ONLY. FINALLY IN SEPTEMBER, THE REAR BRAKE LINES RUSTED THROUGH RIGHT IN MY DRIVEWAY. LUCKILY, I WAS NOT TRAVELING AT SPEED FOR EITHER OF THESE EVENTS, BUT IT WAS A MAJOR EXPENSE AND INCONVENIENCE, ESPECIALLY HAVING IT HAPPEN TWICE LIKE THAT. I ALSO HAD THE LINE ON THE POWER STEERING FLUID COOLER RUST THROUGH IN THE APRIL REPAIR, AND THERE IS WAY MORE RUST IN GENERAL ON THE UNDERCARRIAGE THAN THERE SHOULD BE. THE BODY AND ENGINE ARE JUST FINE. I HOPE YOUR INVESTIGATION LEADS TO A RECALL. *TR

COMPLAINT REPORTS ALLEGE POOR WELD QUALITY AND/OR BENDING OF THE SUBJECT VEHICLE ORIGINAL EQUIPMENT TRAILER HITCH RECEIVER.THE AGENCY'S INVESTIGATION INCLUDED ANALYSIS OF MANUFACTURER AND AGENCY INCIDENT REPORTS, REVIEW OF POLICE REPORTS, ANALYSIS OF THE AGENCY'S FATAL ANALYSIS REPORTING SYSTEM, A VEHICLE OWNER SURVEY, INSPECTION OF TOW VEHICLES/HITCHES AND ANALYSIS OF FAILED PARTS.INCIDENTS OF WELD FAILURE WERE RARE AND ASSOCIATED WITH VERY LOW-SPEED DRIVING (TURNING, BACKING AND SUDDEN STOPPING).INCIDENTS OF BENDING WERE ASSOCIATED WITH IMPROPER TRAILER HITCH ADJUSTMENT OR OVERLOADING. 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 A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL MONITOR THIS ISSUE AND RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.SEE DOCUMENT SEARCH FILE FOR ADDITION INFORMATION.
