I WAS USING MY CHEVY SILVERADO TO TOW MY HORSE TRAILER (HORSE ON BOARD) TO A WEEKEND EVENT.

I WAS USING MY CHEVY SILVERADO TO TOW MY HORSE TRAILER (HORSE ON BOARD) TO A WEEKEND EVENT. BY THE TIME I ARRIVED AT THE CAMP GROUND I REALIZED THAT MY TRUCK'S BRAKES WERE NOT AS FIRM AS THEY SHOULD BE AND THE BRAKE PEDAL WAS GETTING LOWER AND LOWER. I LEFT MY TRAILER AT THE CAMP AND DROVE MY TRUCK TO A NEARBY GARAGE. A MECHANIC LOCATED A LEAKING BRAKE LINE DIRECTLY BENEATH THE DRIVER'S SIDE DOOR AND NOTED THAT ALL THE VISIBLE BRAKE LINES LOOKED CORRODED. I TOPPED OFF THE BRAKE FLUID AT THE GARAGE AND AFTER MY CAMPING WEEKEND I WAS ABLE TO CAREFULLY DRIVE THE TRUCK AND TRAILER HOME BUT I HAD TO USE THE TRAILER'S BRAKE CONTROLLER TO INCREASE THE TRAILER BRAKING TO ASSIST THE TRUCK BRAKING. DURING THE FOLLOWING WEEK THE TRUCK WAS TAKEN TO A GM DEALERSHIP AND THEY DID A SO CALLED REPAIR BY SPLICING NEW PIECES OF ALUMINUM BRAKE LINE INTO THE CORRODED ORIGINAL LINES. *TR

DEAR NHTSA, I WAS READING THIS ARTICLE (I.E. LINK HTTP://TRUCKS.ABOUT.COM/B/2010/04/08/BRAKE-LINE-CORROSION-SUSPECTED-IN-GM-TRUCKS.HTM) AND THIS PROMPTED ME TO CONTACT YOU. I HAVE A 2002 CHEVY SILVERADO 2500 PICKUP TRUCK. DUE TO CORRODED AND EXCESSIVE RUSTED-OUT BRAKE LINES, I EXPERIENCED TOTAL BRAKE LINE FAILURE CAUSING ME TO GET INTO AN ACCIDENT. THIS HAPPENED IN NOVEMBER OF 2008 AND; I ONLY HAD 50,825 MILES ON MY VEHICLE AT THE TIME. LUCKILY FOR ME, I WAS (FOR THE MOST PART) IN STOP AND GO TRAFFIC. IF I WASN'T, I TRULY BELIEVE THINGS COULD HAVE BEEN MUCH WORSE RESULTING IN SEVERE INJURY OR DEATH. THIS HAPPENED ON ROUTE 495 NORTH, A THREE-LANE HIGHWAY NEAR LOWELL MASSACHUSETTS. AS IT WAS, I REAR-ENDED A PICKUP TRUCK IN FRONT OF ME THAT SUBSEQUENTLY HIT THE VEHICLE IN FRONT OF HER. FORTUNATELY... NO ONE WAS SERIOUSLY HURT. I DON'T EVEN WANT TO THINK WHAT MIGHT OF HAPPENED IF I WAS DOING 65 - 70 MPH AND HAD TO AVOID ANOTHER VEHICLE OR BRAKE QUICKLY. I CONTACTED GM ABOUT THIS BUT NEVER RECEIVED A REPLY BACK. MY TOTAL FAILURE OF BRAKES WAS VERIFIED AT THE SCENE BY THE TOW TRUCK DRIVER (CERTIFIED MA MECHANIC), THE STATE POLICE PERSON, MY INSURANCE COMPANY, AND LANNAN CHEVROLET OF LOWELL WHO HAD TO REPLACE EVERY BIT OF BRAKE LINE(S). *TR

MY 2002 CHEVY SILVERADO WITH DURAMAX DIESEL ENGINE BROKE DOWN WHILE ON A TRIP FROM MICHIGAN TO FLORIDA. THE DIESEL INJECTOR CASING FAILED CAUSING THE CRANKCASE TO OVERFILL WITH DIESEL FUEL THEN CAUSED OIL AND DIESEL FUEL MIX TO COME OUT OF THE ENGINE WHILE TRAVELING DOWN THE ROAD COVERING THE UNDERSIDE OF THE VEHICLE AND ROADWAY AS WELL AS VEHICLES DIRECTLY BEHIND ME. THE GM DEALER IN GEORGIA STATED WE WERE IN BY MILEAGE BUT OUT OF THE EXTENDED 7 YEAR 200000 MILE INJECTOR WARRANTY BY 1YEAR AND 4 DAYS AND THE COST WOULD BE $6250 TO REPLACE 8 INJECTORS. THEY OFFERED A 10% DISCOUNT OFF THAT REPAIR. SUBSEQUENT CALLS TO GM CUSTOMER ASSISTANCE WERE MADE TO NO END (THEY STATED THE 10% DISCOUNT WAS THEIR BEST OFFER). I PLEADED THAT THE TIME LIMIT SHOULD NOT BE A FACTOR AS THIS SHOULD NOT AFFECT WEAR (INJECTORS DO NOT FAIL WHEN THEY ARE NOT OPERATING) MY VEHICLE HAS 120000 MILES ON IT (WELL UNDER 200000 WARRANTY AS STATED BY THE CUSTOMER ASSISTANCE REP). I PAID EXTRA FOR THE DIESEL FOR LONGEVITY AND FUEL ECONOMY AS I AM ON A FIXED INCOME BUT WOUND UP BEING TREATED UNFAIRLY ESPECIALLY FOR A KNOWN PROBLEM AND THE FACT THAT OIL/FUEL BLOWING OUT ON THE HIGHWAY AND VEHICLES IS A SAFETY AND EMISSIONS DEFECT. I WOULD LIKE SOMEONE FROM THE NHTSA TO CONSIDER INVESTIGATING THIS ASPECT (TIME LIMIT) AND SAFETY OF DRIVERS AND FIGHTING FOR ME TO GET ASSISTANCE. THANKS FOR LISTENING
