2004 Chevrolet Silverado 2500

HYDRO BOOST HAS FAILED. IT WAS DISCOVERED BY GARDNERVILLE AUTO IN GARDNERVILLE, NEVADA . ON WEDNESDAY 1/15/2020. I CONTACTED GENERAL MOTORS AND THEY SAID THERE NO RECALLS ON THIS VEHICLE. THEY SHOWED OLD RECALLS ON LIGHTING AND POWER STEERING BUT NOTHING ON THE HYDRO BOOST. THE GARAGE SHOWS THREE DIFFERENT RECALLS ON THE HYDRO BOOST, TWO OF WHICH WERE REPORTED BY NTSB.

ON THE 17TH OF AUG., 2017, I WAS ON MY WAY CAMPING PULLING A 28 FT RV WITH MY 3/4 TON CHEV PU, WHEN MY LEFT REAR TIRE WENT FLAT. I PUT ON THE SPARE TIRE AND DROVE 12 MILES AND THE LEFT FRONT TIRE WENT FLAT, THE NEXT DAY I WENT INTO A TIRE SHOP FOR NEW TIRES AND MY OTHER TWO GOOD TIRES WERE BOTH LEAKING AT THE VALUE STEM. THE ONLY DAMAGE WAS THE TIRES.

DRIVING A 2004 CHEVROLET 2500HD 4X4 6 LITER CREW CAB WITH 143005 MILES. TRAVELING AT 55 MPH AS I APPROACHED MY TURN ONTO A SIDE STREET AT APPROXIMATELY 100 YARDS OUT I APPLIED BRAKES TO REDUCE SPEED TO 15/20 MPH TO MAKE 90 DEGREE DOWNHILL RIGHT TURN. I EXPERIENCED A VERY SPONGY BRAKE FOR A COUPLE OF SECONDS FOLLOWED BY THE BRAKE PEDAL GOING COMPLETELY TO FLOOR. I PUMPED BRAKES SEVERAL MORE TIMES WITH THE SAME BRAKE PEDAL RESPONSE AND ZERO BRAKING. MY SPEED HAD ONLY DROPPED TO ABOUT 40 MPH, TOO FAST TO NEGOTIATE MY TURN. I CONTINUED ON THE HWY TO THE NEXT STREET USING MY PARKING BRAKE AND DOWN SHIFTING. SAFELY PARKED, I GOT OUT OF TRUCK AND NOTICED A LARGE AMOUNT OF FLUID WAS RUNNING ON THE GROUND, DRIVERS SIDE FORWARD PART OF CAB, RESULTING IN A COMPLETE LOSS OF BRAKES. MY LEFT FRONT STEEL BRAKE LINE LOCATED ON TOP OF FRAME UNDER DRIVER SIDE AT FIREWALL HAD BURST. ALL 4 BRAKE LINES IN THAT 4" LONG AREA WERE BADLY RUSTED. REMOVED ALL THE BRAKE LINES AND THAT APPEARS TO BE THE HEAVIEST AREA OF HEAVY RUST.

GM PICK UP TRUCKS HAVE WHAT IN MY OPINION IS A SAFETY ISSUE WITH INSTRUMENT CLUSTERS FAILING. ONE CAN BE CRUISING ALONG AND ALL OF A SUDDEN THE SPEEDOMETER GOES CRAZY. MINE REGISTERS 120 MPH AT ALL TIMES. IT PUTS ONE IN UNKNOWN TERRITORY WHEN IN HEAVY TRAFFIC NOT TO MENTION NOT KNOWING WHEN ONE IS SPEEDING. FURTHER ONE DOES NOT HOW MUCH FUEL THEY HAVE OR IF THEIR VEHICLE IS OVERHEATING. GM SENT LETTERS TO OWNERS OF THESE VEHICLES INDICATING THAT THEY WOULD REPLACE THE CLUSTER IF IT WENT BAD BEFORE 72000 MILES.THEY KNOW THAT ANY OR ALL OF THE CLUSTERS ARE PRONE TO FAILURE AND GM SHOULD BE REQUIRED TO ISSUE A RECALL AND CORRECT THIS PROBLEM AT NO COST TO THE OWNER.THE LOCAL GM DEALER TELLS ME THAT IT IS ABOUT A $300. FIX.GM SHOULD NOT BE ALLOWED TO GET AWAY WITH SELLING VEHICLES WITH SUCH POTENTIAL SAFETY ISSUES. *TR
