My truck is a older model Chevrolet Silverado pickup HD the problem is it say engine power reduced. I have had it worked on a few times and keeps reducing if engine power. Can you tell me if there is a recall on this issue or at one point there was a recall? I have had the truck almost 2 years any info would be appreciated. I bought the truck from an individual.
My engine has been giving me lean condition codes p0171, p0174 and truck is lacking performance really bad and coolant problems too please message me back
TAKATA RECALL. WHILE DRIVING ON A CITY STREET, TRUCK SUDDENLY LOST POWER AND SHUT OFF IN THE MIDDLE OF AN INTERSECTION, WHILE I WAS TURNING.I TRIED SEVERAL TIMES TO START IT BUT NOTHING. I BELIEVED IT TO BE THE CATALYTIC CONVERTER, AND HAD IT TOWED TO A MUFFLER SHOP. AFTER FIXING THE PROBLEM TRUCK STILL WOULD NOT CRANK. I HAD TO HAVE IT TOWED ONCE AGAIN TO MY RESIDENCE. BEFORE THIS I WOULD HAVE TO MAKE 2-3 ATTEMPTS TO CRANK THE TRUCK BEFORE IT WOULD START. ALSO PRIOR TO THIS I NOTICED I HAVE NOT BEEN GETTING AS GOOD OF GAS MILEAGE AS I SHOULD AND THE TRUCK WOULD NOT ACCELERATE AS IT SHOULD. I HAVE DONE RESEARCH AND SEEN A NUMBER OF PEOPLE WITH MY SAME MODEL TRUCK HAVE SEVERAL ISSUES WITH THEIR FUEL PUMP.
THE REAR FUEL TANK STRAP HOLDING THE FUEL TANK TO THE FRAME OF THE VEHICLE HAS RUSTED/CORRODED AND FAILED. THE RESULT WAS THE TANK STRAP SEPARATING FROM THE PORTION NEAR WHERE THE STRAP BOLTS TO THE FRAME. THE VEHICLE WAS IN MOTION ON PRIMARY CITY ROADS DURING THIS ISSUE. THE SEPARATED FUEL TANK STRAP THEN RUBBED AGAINST THE REAR PORTION OF THE DRIVE SHAFT NEAR THE REAR AXLE HOUSING. THIS CAUSED IT TO SEPARATE FROM THE VEHICLE AND ENTER THE ROADWAY. AFTER THE RETAINING STRAP FAILED, THE REAR PORTION OF THE FUEL TANK WAS THEN HANGING DANGEROUSLY LOW TOWARDS THE ROADWAY.
FUEL PUMP WENT OUT WHILE DRIVING ON THE HIGHWAY (VERY DANGEROUS). TRUCK JUST DIE WHILE DRIVING. HAVE IT CHECK TO LEARN THE FUEL PUMP IS NEEDS TO REPLACE. I DID A LITTLE RESEARCH AND FIND OUT THIS IS A COMMON PROBLEM TO THIS TRUCK ... RECALL?
MY BRAKE LINE RUSTED OUT CAUSING BRAKE FAILURE AND MY FUEL LINE RUSTED OUT CAUSEING FUEL LEAK. THE BRAKES WENT OUT IN MOTION FUEL LINE ALSO.
BRAKE LINES COMPLETELY RUSTED THRU, HAD TO REPLACE ALL LINES, FUEL LINES RECENTLY LEAKED AND UPON INSPECTION ARE FOUND TO BE COMPLETELY RUST AS WELL, BAD MATERIAL USED IN THESE LINES, BIG SAFETY ISSUE WITH LEAKING FUEL AND INABILITY TO STOP WHEN BRAKES GO OUT
VEHICLE WILL SUDDENLY DECREASE POWER AND THE MESSAGE "ENGINE POWER REDUCED" SHOWS ON MESSAGE DISPLAY. FIRST TIME WAS 9/8/2012. LAST TIME WAS FEB 24, 2015. HAS DONE THIS AT 25 MPH ON A CITY STREET, 35 MPH CITY STREET TWICE, AND 55 MPH ON HIGHWAY. SUPPOSEDLY REPAIRED THREE TIMES. AM AFRAID TO USE VEHICLE AS USUALLY TOW 5TH WHEEL AND DO NOT WANT IT TO DO THIS WHILE TOWING.
SOUND COMING FROM TRANSMISSION WHEN PUSH ON GAS,NO POWER ON RIGHT SIDE GEAR LIGHT DOESN'T WORK I SERVICE 4 WD IT'S TELL ME TO SERVICE I START UP IT'S PICKS WHICH GEAR (STATIONARY) DOOR ON RIGHT STOP WORKING LOST ALL POWER.
ON MULTIPLE OCCASIONS THE VEHICLE HAS LOST POWER AT HIGHWAY SPEED AND THE ENGINE DIES. AFTER A FEW ATTEMPTS THE ENGINE RESTARTS AND OPERATES NORMALLY FOR AN UNPREDICTABLE INTERVAL. THIS HAS HAPPENED AT LEAST 10 TIMES. THE AUTHORIZED DEALER AND OTHER MECHANIC SHOPS HAVE NOT BEEN ABLE TO DIAGNOSE THE REASON FOR THE POWER FAILURE AS THEY HAVE NOT BEEN ABLE TO CAUSE IT TO DUPLICATE FAILURE WHEN THEY HAVE IT. THIS SUDDEN UNEXPECTED CONDITION IS VERY DANGEROUS WHEN IT OCCURS AND RENDERS THE VEHICLE UNUSABLE FOR ANYTHING OTHER THAN SHORT USAGE. *JS
WHILE LOOKING AT MY TRUCK AFTER GETTING IT BACK FROM THE SHOP GETTING ALL 4 OF THE BRAKE LINES REPLACED, I NOTICED THE FUEL LINES ARE LEAKING AND EXTREMELY CORRODED. I HAVE ALWAYS BEEN A CHEVY LOVER, AND THIS IS MY FIRST NICE VEHICLE I HAVE EVER OWNED. BOUGHT USED IN SEPTEMBER OF 2014. SO FAR WE HAVE NOTICED THAT JUST ABOUT EVERY RECALL FROM THE PAST WAS NEVER FIXED ON OUR TRUCK, SO WE HAD TO SHELL OUT ALMOST $900 TO REPLACE THE BRAKE LINES FRONT TO BACK. NOW THE FUEL LINES, THE WINDSHIELD SEEMS LOOSE, THESE ARE ALL RECALLS FROM THE PAST. IT DOESN'T MAKE SENSE TO PUT A TIME FRAME ON RECALLS CONSIDERING SOME PEOPLE MAY NEVER FIND OUT TIL IT'S TOO LATE, AND OTHERS MAY NOT FIND OUT TIL SOMEONE GETS HURT. *TR
DURING COMMUTE TO WORK ON 22 APRIL 2014, AS I WAS APPROACHING A STOPLIGHT AND PRESSED THE BRAKES TO SLOW DOWN, THE MAIN CONSOLE CHIMED, SHOWED A MESSAGE TO CHECK BRAKES, AND I WAS ABLE TO PRESS THE BRAKE LEVER TO THE FLOOR. I WAS STILL ABLE TO STOP PRIOR TO REACHING THE STOPLIGHT. I SLOWLY RETURNED HOME (ABOUT A MILE) AND WAS ABLE TO STOP THE TRUCK NEARBY, THOUGH THE BRAKES WERE NO LONGER ABLE TO STOP THE VEHICLE WHILE IN DRIVE. WHEN PLACED ON THE FLATBED TOW TRUCK, THE DRIVER NOTICED THAT THE BRAKE FLUID WAS LEAKING ONTO THE BED. AT THE DEALERSHIP, THE MECHANICS STATED THE BRAKE LINES WERE CORRODED AND THE ENTIRE SYSTEM NEEDED TO BE REPLACED BEHIND THE MASTER CYLINDER. ADDITIONALLY, I HAD ASKED THEM TO INSPECT WHY I SOMETIMES HAD DIFFICULTY STARTING THE VEHICLE WHICH WAS DIAGNOSED AS A FAULTY FUEL PUMP. THIS COULD NOT BE REMOVED FROM THE FUEL TANK (DUE TO CORROSION), AND I WAS FORCED TO REPLACE THE ENTIRE TANK SYSTEM TO REPLACE THE PUMP. *TR
MY SON [XXX] WANTED A 4X4 TRUCK SO THIS GUY [XXX] SAID HIS WAS FOR SALE HE COULD TEST DRIVE IT,WELL THE 4X4 DID NOT WORK ON THE TRUCK THE MINUTE MY SON SHIFTED IT IN TO 4 WHEEL DRIVE THE TIRE ROD AND SOMETHING ELSE,SO MY DAUGHTERS FATHER [XXX] WORKS ON VEHICLES AND SALES THEM TOO. WELL I ASKED [XXX] TO HELP GET MY SONS TRUCK BACK FROM [XXX] AND FIX NICKS TRUCK SO WE COULD HAVE A VEHICLE BECAUSE WE WERE SHARING ONE VEHICLE. NICK WANTED AND [XXX] WANTED FINALLY [XXX] FIXED [XXX] TRUCK AND WHEN WE GOT MY SON TRUCK BACK IT WAS MAKING A NOISE,SO [XXX] SAID HE THINKS ITS THE FUEL PUMP NO BIG DEAL,I SAID OK. HE GAVE ME AND ESTIMATE TO FIX NICKS TRUCK OF 2000.00, WELL SOMEONE AT [XXX]"S WAS RIPPING ME OFF IT WAS ONLY 600.00 R AROUND THAT AMOUNT. WELL ME AND MY HUSBAND WERE GOING THROUGH A BAD DIVORCE HE HAD JUST SIGN OVER THE TITLE AND REGISTRATION TO ME,AND IT WAS LEFT IN GLOVE BOX MY FAULT,BUT HE FORGED THE DOCUMENTS PLUS CASH A 500.00 CHECK THAT I STOPPED PAYMENT ON. I MADE TO POLICE REPORTS PLUS THERE'S 2 911 CALLS WHERE WE R CHASING HIM BUT THE SPEED WAS GETTING OUT OF HAND I TOLD MY SON TO BACK OFF,WE PAID 1500.00 FOR THE TRUCK OUR LIFE IS WORTH MORE. I GOT THE COMPLAINT NUMBERS COPS DID NOTHING. WENT TO DMV HE TRIED TWICE THERE TO SWITCH IT THEY TURNED HIM DOWN,SO HE WENT TO A TITLE COMPANY IN LAFAYETTE,LA ON JOHNSTON STREET AND GOT IT DONE. PLUS I PAID MY INSURANCE FOR SIX MONTHS AHEAD, I REPORTED IT TO PROGRESSIVE THEY WERE MAILING MY REFUND CHECK,HE STOLE THAT AND APPLIED IT BACK I THINK HE R SOMEONE GOT IN A WRECK AND TRIED TO CLAIM A INSURANCE CLAIM. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
I APPROACHED AN INTERSECTION WHERE MY TRAFFIC LIGHT SIGNAL WAS RED AND I HAD SUDDEN LOSS OF BRAKING IN MY 2003 SILVERADO C1500, WITH NO PRIOR INDICATION OR WARNING LIGHTS. THE BRAKE PEDAL WENT VERY LOW AND I COULD NOT STOP MY VEHICLE BEFORE ENTERING THE INTERSECTION. I STEERED TO THE RIGHT OF TWO WAITING CARS IN FRONT OF ME AND CAME TO A STOP IN THE INTERSECTION BEYOND THE LIGHT. FORTUNATELY THERE WERE NO VEHICLES COMING AT THAT MOMENT ON THE 4 LANE HIGHWAY CROSSROAD SO A CRASH WAS AVOIDED. ALL OF THE BRAKE AND FUEL LINES WERE INSPECTED AFTER THE INCIDENT AND FOUND TO BE HEAVILY CORRODED (RUSTED), WITH THE REAR BRAKE LINE LEAKING ABOUT 2 INCHES FROM WHERE IT EXITS THE ABS UNIT UNDER THE CAB. THE MASTER CYLINDER FLUID LEVEL WAS NORMAL AND THERE WERE NEVER ANY PREVIOUS LEAKS, WARNING LIGHTS, OR PROBLEMS LIKE THIS AND I AM THE ORIGINAL VEHICLE OWNER. THE VISIBLE LEVEL OF CORROSION SEEMS EXTREME ON THE BRAKE AND FUEL LINES ON THIS VEHICLE. HAD I BEEN IN AN ACCIDENT, I WOULD BE CONCERNED THAT FUEL LINES COULD ALSO LEAK AND INCREASE THE LIKELIHOOD OF A FIRE DUE TO THEIR LIKEWISE POOR CONDITION DUE TO EXTREME RUST. *TR
THE BOLTS ARE BROKEN OFF IN THE MANIFOLD, AFTER CHECKING YOU-TUBE I FOUND THIS IS A PROBLEM THE GM HAS CHOSEN TO IGNORE. *TR
MY WIFE WAS DRIVING OUR 2003 CHEVROLET SILVERADO 4X4 PICKUP ON SECONDARY STATE ROUTE. WHILE DESCENDING AN APPROXIMATE 6% GRADE INTO A RIGHT HAND TURN AT BOTTOM SHE DEPRESSED THE BRAKE PEDAL TO SLOW FOR THE GRADE AND TURN AND IT WENT TO THE FLOOR, THE SERVICE BRAKE MESSAGE CAME UP IN THE DIC AND THE DOOR CHIME SOUNDED. SHE PULLED OVER AS SOON AS POSSIBLE AS SHE WAS SHAKEN FROM RIDING OUT THAT HILL AND TURN WITH MINIMAL BRAKES AND CALLED ME. I WENT OUT AND DROVE THE TRUCK BACK TO OUR HOME AND PUT IN THE GARAGE TO INSPECT THE PROBLEM. ONCE UNDER THE TRUCK I FOUND BRAKE FLUID DRIPPING FROM THE SIDE OF THE FUEL TANK AND FRAME AREA UNDER THE CAB AND BED OF THE TRUCK. THE SERVICE BRAKE LINE FROM THE ABS BLOCK TO THE REAR FRAME POINT WHERE THE BRAKE HOSE TO THE REAR AXLE MOUNTS WAS CORRODED THROUGH AND LEAKING. FURTHER INSPECTION SHOWED ALL BRAKE HARD LINE PLUMBING TO BE IN POOR CONDITION AND ALSO THE FUEL LINES SHOWING HIGH CORROSION. A CALL TO A LOCAL GM PARTS COUNTER REVEALED THAT GM DOES NOT MAKE A REPLACEMENT SET FOR THESE LINES AND THAT A TECHNICIAN WOULD NEED TO FIELD BEND AND MAKE UP EACH LINE. LATER RESEARCH PROVED THIS TO BE WRONG AS GM OFFERS A DEEPLY DISCOUNTED UNADVERTISED LINE SET FROM AC DELCO. IN RESEARCHING FINDING PARTS TO REPAIR, I HAVE FOUND THIS TO BE A COMMON PROBLEM WITH CHEVROLET/GMC TRUCKS FROM ABOUT 1999 UP ACCORDING TO THE VARIOUS TRUCK OWNER FORUMS ONLINE. DRIVING THE VEHICLE HOME AT SLOW SPEED, BRAKING WAS VERY MINIMAL WITH THE REAR BRAKE CIRCUIT OUT,AND THE KNOWLEDGE OF POOR BRAKE OPERATION, SO THEREFORE IT IS MY OPINION THAT THIS IS A SAFETY ISSUE WITH THESE VEHICLES WITH THE POTENTIAL OF INJURY OR EVEN DEATH WHEN ALL THE FACTORS COMBINE POORLY, AND AT THE LEAST, GM SHOULD BE REQUIRED TO NOTIFY OWNERS OF THIS POTENTIAL PROBLEM WITH THEIR VEHICLE, IF NOT RECALL AND REPAIR THOSE EFFECTED VEHICLES. *TR
WELL ABOUT MID 2012 THE BRAKE LINES JUST RUST OUT IN THE MIDDLE OF THE TRUCK AND THE REAR. MY GIRL FRIEND WAS DRIVING IT TO WORK AND LOST ALL THE PEDAL PRESSURE. THANK GOD SHE WAS GOING UP IN THE PARKING GARAGE. RIGHT NOW I'M TRYING TO REPLACE LINE FUEL LINES. IT JUST STARTED POURING GAS OUT AFTER I JUST GOT TO WORK. I NURSED IT HOME AND MADE IT. THE RETURN LINE IS JUST ALL RUSTED OUT. THEN I NOTICED ALL THREE LINES WHERE ALL RUSTED OUT. IT'S TO BAD NOTHING HAS BEEN DONE YET I CAN'T AFFORD THIS! IT IS WELL KNOWN AND UNDERSTOOD BY MANY THAT THIS IS A BIG PROBLEM. ALSO TO TOP THAT THE FRAME LOOKS MORE RUSTED THAN THE 1989 DODGE I JUST GOT RIDE OF. I WASH UNDER THE TRUCK THROUGH OUT WINTER AND DON'T UNDERSTAND WHY IT'S SO BAD ALREADY. *TR
FUEL LEAKING FROM FUEL LINE NEAR FRONT OF GAS TANK. UPON INSPECTION, FUEL LINE WAS ROTTED THROUGH. FURTHER INSPECTION BY MECHANIC FOUND FUEL AND VAPOR RETURN LINES WERE ALL CORRODED AND NEEDED TO BE REPLACED. A LEAKING FUEL LINE COULD CAUSE A FIRE. ALL BRAKE LINES WERE REPLACED TWO YEARS AGO DUE TO CORROSION AND FAILURE OF A BRAKE LINE WHILE DRIVING DUE TO THE CORROSION. CHEVY DEALER REFUSED TO REPAIR THE BROKEN LINE, INSISTING THAT ALL BRAKE LINES MUST BE REPLACED DUE TO THE CORROSION. REAR BRAKE SHIELDS HAVE ALSO ROTTED AWAY, AND THE DIFFERENTIAL COVER IS ALSO ROTTING. THESE WILL ALSO REQUIRE REPLACEMENT. NONE OF THE CORRODED PARTS DESCRIBED HERE HAVE ANY KIND OF COATINGS TO PREVENT CORROSION. BRAKE AND FUEL LINE CORROSION ARE COMMON PROBLEMS ON THIS MODEL AND YEAR, AND CHEVROLET OR NHTSA DO NOT APPEAR TO BE ABLE OR WILLING TO DO ANYTHING ABOUT IT. *TR
ON 09/10/13, 1:45 PM, I WAS DRIVING EAST ON S.R. 73 NEAR I-75 INTERSECTION. AS I APPROACHED THE INTERSECTION TRAVELING APPROXIMATELY 35 MPH, THE LIGHT CHANGED TO YELLOW. I BRAKED SOMEWHAT HARD AND THE BRAKE PEDAL WENT TO THE FLOOR BOARD. THERE WAS NO BRAKING CONTROL AT ALL AND I PROCEEDED THROUGH THE RED SIGNAL. APPROXIMATELY 500 FEET AFTER GOING THROUGH THE INTERSECTION I MANAGED TO STOP IN THE MEDIAN. FORTUNATELY, ALTHOUGH TRAFFIC WAS HEAVY, NO CONTACT OCCURRED. IMMEDIATE INSPECTION REVEALED A BRAKE LINE RUSTED THROUGH. I TRAILERED THE TRUCK TO A CHEVROLET DEALER WHO FOUND NOT ONLY "ALL" THE BRAKE LINES WERE DANGEROUSLY RUSTED, BUT THE GAS LINES ALSO WERE DANGEROUSLY RUSTED. THE DEALER STATED THIS WAS A COMMON OCCURRENCE WITH CHEVROLET SILVERADO. REPLACEMENT OF THESE ITEMS REQUIRED REMOVING THE TRUCK BED WHICH REVEALED THE BRAKE ROTOR BACKING PLATES RUSTED "AWAY." SEVERE FRAME AND COMPONENT RUST WAS ALSO FOUND. ONLY REPAIRED BRAKE AND GAS LINES. COST, $1,765.11 OH, BY THE WAY, THE "SERVICE BRAKE SYSTEM" WARNING LIGHT CAME ON AFTER BRAKE FAILURE.
HAD HOOKED TRUCK TO A CAR TRAILER AND STEPPED ON BRAKES TO PUT TRUCK IN DRIVE AND BRAKE PEDAL WENT TO FLOOR, THERE WAS NO BRAKES AT ALL. UPON EXAMINING I FOUND THAT THREE BRAKE LINES HAD FAILED. THE TRUCK WAS TOWED TO A LOCAL GARAGE AND THEY FOUND THAT ALL BRAKE LINES AND ALSO THE FUEL LINES WERE BADLY RUSTED AND HAD TO BE REPLACED.
WAS ATTEMPTING TO BACK VEHICLE AND CAMPER TRAILER DOWN INCLINED DRIVEWAY WHEN SUDDENLY THE BRAKE PEDAL WENT COMPLETELY TO THE FLOOR AND I HAD ABSOLUTE MINIMUM BRAKING FORCE. WAS ABLE TO STOP VEHICLE BEFORE IT AND TRAILER WENT OVER THE HILL, (AN APPROXIMATE 15 - 20 FOOT DROP IF IT HAD OCCURRED). UPON INSPECTION I FOUND BRAKE FLUID ON THE DRIVEWAY. UPON FURTHER INSPECTION I DISCOVERED THAT A BRAKE LINE LEADING FROM THE MASTER CYLINDER TO THE ABS CONTROLLER WAS LEAKING. UPON FURTHER INSPECTION I FOUND THAT ALL THE BRAKE LINES WERE SEVERELY CORRODED AND READY TO FAIL. I CANNOT BELIEVE HOW MUCH RUST IS PRESENT ON THE BRAKE LINES AND THE FUEL LINES. THIS APPEARS TO BE A MAJOR ACCIDENT WAITING TO HAPPEN. *TR
THE UNDER SIDE OF TRUCK IS RUSTING OUT. ALL THE CALIPERS, BRAKE LINES, AND FUEL LINES ARE RUSTED BADLY. I HAVE HAD TO REPLACE TWO BRAKE LINES ALREADY. ALSO THE FRAME IS RUSTED. *TR
UPON STARTING THE VEHICLE AND DEPRESSING THE BRAKES, THE BRAKES WENT TO THE FLOOR. UPON INSPECTION FROM A MECHANIC, IT WAS NOTED THAT BOTH BRAKE LINES WERE ROTTED (ONE WAS ROTTED ALL THE WAY THROUGH CAUSING THE FLUID TO LEAK FROM THE LINE). WE WERE ALSO TOLD THAT THE GAS LINE AND CALIPER HAD SEVERE ROTTING. UPON MY RESEARCH, THIS SEEMS TO BE A VERY COMMON PROBLEM WITH CHEVROLET TRUCKS. I HOPE THIS WILL BE RESOLVED SO ADDITIONAL CHEVROLET OWNERS DO NOT HAVE SEVERE ACCIDENTS DUE TO THESE ISSUES. MY HUSBAND AND 4 YEAR OLD SON HAD TO WALK QUITE A FEW MILES IN 95 DEGREE WEATHER! THIS IS A SAFETY ISSUE AND I HOPE MY COMPLAINT WILL HELP FURTHER THE INVESTIGATION. *JS *TR
AN ODOR OF GASOLINE WAS EMANATING FROM THE VEHICLE. THE SERVICING DEALER DIAGNOSED RUSTED THROUGH FUEL LINES, ALL OF WHICH HAD TO BE REPLACED. *TR
BRAKE LINE RUSTED OUT. STARTED THE TRUCK AND WHEN I PUSHED ON THE PEDAL IT WENT TO THE FLOOR. I LIVED IN INDIANA FOR 8 YEARS OF OWNING THE TRUCK. I HAVE LIVED IN FLORIDA FOR THE LAST TWO YEARS. ALL LINES FROM THE FRONT OF THE TRUCK TO THE ABS MODULATOR ARE RUSTED. THE REAR LINE IS OK. THE PROBLEM IS EXACERBATED BY RUNNING THE LINES WHERE THEY ARE. THE FUEL LINES APPEAR TO HAVE A SIMILAR PROBLEM BUT HAVE NOT YET FAILED. *TR
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
