1999 GMC Sierra 1500 Problems

ABS Brakes cut out leaving you with little to no brakes. No warning light appears. This continues on and off over time. Then that ABS warning light came on. When the warning light was on, brakes worked just not ABS. Light would go out and back to the original issue. Took it in to dealership when the light remained on. They reset the light and told me every thing was fine. And charged me $$$. ABS Brake warning light can right back on. Had the manager drive it. Told me it was fine, brakes worked well. The ABS warning would go in and out. Removed the ABS fuse, so I could depend on being able to stop, without having to worry about the ABS cutting in and out for a few years. Watched for recalls, nothing appeared. Noticed on blogs, others were having the same issue. Took it to a great mechanic! Who verified there were no leaks in the brake lines, replaced one line that had been known to have issues on this type of truck and verified there were no air bubbles on the lines. Still same issue, then replaced the computer system for the ABS. No codes ever came up on the computer system that I can recall. Had more issues with the ABS. Would go to stop, (generally on a hill) then when it came to the final stopping, I had NO BRAKES, had to slam on the brakes to stop. ABS Brake warning lights never came on. My mechanic looked and looked and relooked into this. Found from others that blogged that they had similar issues, that one or both of the ABS Brake sensors were not responding evenly causing an issue. Changed out the sensor. All is good now. This issues could have put and my family in danger a number of times. I was blessed to avoid a few accidents by driving far enough behind people and or had an emergency line to pull into when unable to stop. Hope a recall comes soon for these issues to prevent someone from being killed. These took place from about 2015-fixed 2020. Email me with a report number and where I can upload info at a later date, I will do so.

I WAS DRIVING HOME FROM WORK ON 421 IN EMINENCE, KY. I PUSHED THE BRAKE PEDAL & I HAD NO BRAKES RIGHT IN FRONT OF HARRY HILL PARK. GM & I ARE VERY LUCKY THAT NO ONE WAS KILLED YESTERDAY. THE BRAKE LINE CORRODED & LEAKED THE BRAKE FLUID, SO WHEN I PUSHED THE PEDAL, IT WENT RIGHT TO THE FLOOR. THE VEHICLE IS PRETTY CLEAN & AFTER CHECKING MANY BLOGS & YOUTUBE VIDEOS THIS IS A VERY COMMON PROBLEM ON GM TRUCKS. I CHECKED THE RECALLS ON THIS TRUCK & THE TAILGATE CABLE IS RECALLED FOR BREAKING UNDER LOAD DUE TO CORROSION; THIS COULD INJURE SOMEBODY, BUT NOT AS VITAL COMPARED TO THE BRAKING SYSTEM AS SOMEONE COULD DIE IN A HORRIBLE INCIDENT. I WOULD GREATLY APPRECIATE YOUR ATTENTION TO THIS SERIOUS MATTER. THANK YOU

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE COMING TO A STOP, THE LATCH THAT HELD THE DRIVER SEAT IN PLACE FAILED. THE CONTACT STATED THAT THE SEAT WOULD SLIDE FORWARD AND BACK. THE VEHICLE WAS NOT DIAGNOSED OR REPLACED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 81,316.

AFTER LETTING MY SON EXIT ON THE DRIVERS SIDE, TRIED TO RETURN SEAT TO NORMAL POSITION AND COULD NOT. AFTER STRUGGLING WITH IT, A PLASTIC PART IN THE SEAT TRACK BROKE AND THEN SEAT WOULD NOT STAY IN PLACE AT ALL. CAREFULLY DROVE TO NEAREST GM DEALERSHIP AND WAS TOLD PART WAS NOT IN STOCK, WOULD TAKE UP TO A WEEK AND WAS VERY EXPENSIVE. I WAS ON VACATION, SO COULD NOT WAIT, TRIED SALVAGE YARDS, NO LUCK. HAD UPHOLSTERY SHOP DRIVE LARGE SCREW INTO TRACK TO LOCK IT IN PLACE AND HAVE NOT BEEN ABLE TO LOCATE A PART. *TR

I PURCHASED THIS TRUCK A FEW MONTHS AGO. WITHIN A WEEK I HAD A CO WORKER POINT OUT THE BED WAS LEANING TOWARD THE CAB. A FEW WEEKS LATER WE GOT UNDER THE TRUCK TO FIND OUT WHAT WAS GOING ON. WE NOTICED ALOT OF RUST. I LOOKED ON LINE TO SEE HOW TO FIX IT AND FOUND ALOT OF PEOPLE WERE DEALING WITH THE SAME ISSUE. I DECIDED TO GET SOME SHEET METAL AND WELD IT TO THE FRAME. I THEN ASKED MY BOSS WHO OWNS A WELDER IF HE COULD HELP ME WITH IT. HE SAID THERE WASN'T ANYTHING LEFT TO WELD TO. THEN THE TRUCK STARTED NOT GOING INTO PARK. AND TO START IT YOU'D HAVE TO START IT IN NEUTRAL AND IT WOULD NOT STAY IN PARK, IT WOULD ROLL AND THE EMERGENCY BRAKE NO LONGER WORKED. I THEN HAD MY PARENTS TO TAKE THE TRUCK TO A BODY SHOP TO SEE IF THEY COULD REPAIR IT. BOTH BODY SHOPS SAID IT WAS NOT REPAIRABLE THAT THE FRAME WAS RUSTED OUT AND NEEDED REPLACED. ONE SHOP SAID THAT THE PARKING ISSUE COULD BE FROM THE FRAME BENDING, BUT DID NOT KNOW WITHOUT GETTING INTO THAT. THEY ALSO TOLD THEM THAT THE TRUCK WAS UNSAFE TO BE ON THE ROAD. I FINANCED THIS TRUCK FOR $5500 AND NOW I'M PAYING PAYMENTS ON A TRUCK I CAN'T EVEN USE.

BRAKE LINES RUSTED , ABS FAILURE ,GAS LINES RUSTED, TRANS COOLING LINES RUSTED. THESE WERE ALL FAILURES THAT NEEDED REPLACEMENT THROUGH THE YEARS I HAVE OWNED IT. NOW FRAME RUSTED AND CRACKED . TRUCK BASICALLY SHOT .

WHILE DRIVING ON A STREET IN MY NEIGHBORHOOD, WE FOUND THAT THE IGNITION SWITCH COULD BE MOVED TO THE "OFF" OR "ACCESSORY" POSITION WHILE DRIVING. NOTICED THAT STEERING, BRAKES, AND OTHER COMPONENTS BECAME DISABLED. LUCKILY WE WERE ABLE TO SAFELY MOVE THE VEHICLE TO THE ROADSIDE AND ASSESS THE SITUATION. A PROBLEM LIKE THIS COULD RESULT IN CATASTROPHIC SYSTEM FAILURE IN THE VEHICLE WHILE DRIVING AT HIGH SPEEDS, AND COULD CAUSE POSSIBLE DEATH IF WE WEREN'T AWARE OF THIS PROBLEM. PLEASE INFORM OTHER VEHICLE OWNERS OF THIS POSSIBLE DANGEROUS ISSUE.

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. WHILE THE VEHICLE WAS IN NEUTRAL, THE INSTRUMENT PANEL GAUGES FAILED AND FLICKERED WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. THE CONTACT STATED THAT THE VEHICLE MADE AN ABNORMAL GRINDING SOUND FROM THE REAR END AFTER HITTING A POTHOLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE REAR DIFFERENTIAL WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE REAR DIFFERENTIAL WAS REPLACED FOUR TIMES. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 186,000.

COMING TO A STOP SIGN I APPLIED THE BRAKES AND THEY COMPLETELY FAILED WITHOUT WARNING; NO LIGHTS OR INDICATION FAILURE WAS IMMINENT. THE PEDAL WENT TO THE FLOOR WITH NO RESISTANCE. MANAGED TO TURN ONTO A DIRT SHOULDER AND DOWNSHIFT TO STOP. INSPECTION REVEALED RUSTED THROUGH REAR BRAKE LINE. ALTHOUGH THE DASH BRAKE WARNING LIGHT COMES ON WHILE STARTING THE TRUCK, IT GOES OFF AND GIVES NO INDICATION THE BRAKE FLUID IS LOW. WHILE REPAIRING THE BRAKE LINES IT WAS NOTICED THE FRAME OF THE TRUCK IS EXTREMELY RUSTY AND FLAKING. AFTER WIRE-BRUSHING BY HAND,THE FRAME IS SHOWING CRACKS ON BOTH SIDES, UNDER THE CAB, NEAR THE REAR, RIGHT ABOUT WHERE A CROSSMEMBER IS ATTACHED. THIS VEHICLE IS NO LONGER SAFE TO DRIVE. I AM NOT IMPRESSED WITH GM'S CLAIM THAT THIS WAS A LIGHTER, STRONGER FRAME ON THIS TRUCK. WE HAVE 2 OLDER TRUCKS WITH NOWHERE NEAR THIS MUCH RUST AND NEITHER HAVE CRACKED. THE DESIGN ALLOWS TOO MUCH CRUD TO ACCUMULATE INSIDE THE LIP OF THE FRAME WHERE IT IS ALMOST IMPOSSIBLE TO WASH OUT. *TR

BRAKE CHECK ENGINE OIL CHANGE INDICATOR WILL NOT GO OFF

MY GMC SIERRA HAS THE 5.3 V8 ENGINE AND THREE OF THE EXHAUST MANIFOLD BOLTS ARE BROKEN OFF AND IT IS LEAKING EXHAUST FUMES .THESE BOLTS SHOULD NOT BREAK OFF SO EASILY.I FEEL THIS IS A SAFETY ISSUE AND A RECALL SHOULD BE ISSUED TO REPAIR THIS PROBLEM. I KNOW OTHER OWNERS WHO HAVE THE SAME PROBLEM. *TR

I AM THE ORIGINAL OWNER OF A 1999 GMC SIERRA THAT JUST HAD BRAKE LINE FAILURE ON 7/14/16 ON THE INTERSTATE THAT CAUSED AN ACCCIDENT. I HAD COMPLETE LOSS OF BRAKES, PEDAL TO THE FLOOR. I USED LOW GEAR AND PARK BRAKE TO MINIMIZE DAMAGE BUT STILL MADE CONTACT. IT IS CURRENTLY AT PATRIOT BUICK GMC IN WILLIAMSBURG VA FOR REPAIR WHERE I BOUGHT IT NEW. I FEEL ME HAVING TO PAY $1000+ FOR THE BRAKE LINE REPAIR AND NOW A COURT DATE AND INSURANCE ISSUES THAT ARE NOT MY FAULT. WE NEED TO DISCUSS GMC MAKING SOME RESTITUTION AS THERE IS NO RUST ANYWHERE ELSE AND THIS TRUCK HAS ONLY BEEN IN VA. I HAVE OTHER GM CARS FROM THE 60'S, 70S AND 2000S THAT HAVE NO RUST ISSUE. FUEL LINE WAS LEAKING AS WELL AND SOME NEEDED REPLACMENT.GM SERVICE REQUEST 8-2250924255 I ALSO HAD THE PS REAR BRAKE ROTOR SHIELD COME OFF AND SCRAPE MOVING PARTS LAST YEAR. TURNED ITNTO DEALERSHIP AS A PROBLEM. THIS TRUCK WAS TSB'D YEARS AGO FOR LINE INSPECTION

BRAKES COMPLETELY FAILED,FOOTPEDAL WENT DOWN FLOOR. WHILE DRIVING IN RESIDENTIAL AREA.. BRAKE FLUID FOUND LEAKING.HAD TOWED TRUCK ,BRAKE LINES RUSTED THRU AND HAD 4 COMPLETE LINES REPLACED FOR THE SECOND TIME ..I HAVE OWNED TRUCK SINCE 1999. LAST BRAKE LINE REPLACED IN 2015. THE OTHER ITEM WAS FUEL PUMP FAILED ON THE WAY TO WORK AND TRUCK WOULD NOT START.HAD TO HAVE VEHICLE TOWED AT MIDNIGHT AND FUEL PUMP REPLACED.

WHEN DRIVING DOWN THE ROAD WHEN GOING AROUND LEFT CURVE THE STEERING WHEEL JUMPS TO THE LEFT AND COMES BACK. IT DOES NOT HAPPEN ALL THE TIME IT HAS BEEN GOING ON FOR TWO YEARS AND KNOW ONE CAN FIND THE PROBLEM. THIS TRUCK WAS BUILT IN 11/OF 1998.

POWER STEERING SUDDENLY GOES INTO MAX ASSIST WHEN MAKING GRADUAL TURNS CAUSING THE STEERING WHEEL TO JERK OUT OF YOUR HANDS AND ALMOST CAUSING AN ACCIDENT. VEHICLE SWERVED ALL OVER THE FREEWAY UNTIL IT COULD BE STOPPED. APPARENTLY GM IS AWARE OF THE PROBLEM SINCE THEY MAKE A BYPASS KIT (P/N 19168825) TO ELIMINATE THE FAULTY ACTUATOR MOUNTED ON THE POWER STEERING PUMP BUT THEY WILL NOT ISSUE A RECALL EVEN THOUGH THIS IS AN EXTREME SAFETY HAZARD. GM EXPECTS YOU TO BUY A $70 KIT TO REMEDY THE PROBLEM. THIS HAS BEEN AN ONGOING RANDOM INTERMITTENT PROBLEM WITH MY SUBURBAN FOR THE LAST 8-9 YRS. *TR *JS

I NOTICED THE SIDEWALL SEPARATING WHILE MY TRUCK WAS IN THE DRIVEWAY. I HAVEN'T DRIVEN THE VEHICLE SINCE. *TR

ON JAN.15,2003, I PURCHASED FIVE ( 5 ) DUNLOP ROVER A/T BSL TIRES FOR MY 1999 CHEV SUBURBAN FROM JUST TIRES 408 HADDONFIELD RD. CHERRY HILL, NJ 08034 AND PAID CASH FOR SAME. AT THE END OF OCTOBER 2004, MY WIFE HAD A FLAT TO THE RIGHT REAR OF HER VEHICLE, AAA RESPONDED AND CHANGED THE TIRE FOR HER, WHEN SHE TOOK THE TIRE TO A GARAGE FOR REPAIRS, SHE WAS ADVISED THAT SAID TIRE COULD NOT BE REPAIRED DUE TO SEVER CRACKING OF THE INSIDE TIRE WALL NEAR THE RIM, THE MECHANIC PLACED A PLUG IN SAME AND TOLD HER TO GET THE VEHICLE BACK TO JUST TIRES AND ADVISE THEM THAT HE FOUND ALL THE TIRES TO BE IN THE SAME CONDITION, CAUSING AN UNSAFE VEHICLE. WHEN I TOOK THE VEHICLE AND TIRE TO JUST TIRES, I WAS TOLD THAT DUE TO A PLUG BEING INSERTED INTO THE TIRE, WHICH WAS NOT PLACED BACK ON THE VEHICLE, THE WARRANTIES WERE VOIDED AND THEY WOULD NOT DO ANY THING ABOUT IT. MR. CHRIS PENTZ THE MANAGER FURTHER INFORMED ME THAT SINCE I PURCHASED THESE UNDER A CORPORATE NAME AND PAID CASH IT WAS MY PROBLEM. I AM CONCERNED THAT THESE CRACKS IN THESE TIRES COULD RESULT IN A EQUIPMENT FAILURE AND REQUEST THAT DUNLOP REPLACE SAME. MY ODOMETER READING AT THE TIME OF PURCHASE OF THE TIRES WAS 54078 AND READING AT TIME OF FAILURE WAS 79398. *JB

AFTER THE WARRANTY RAN OUT AND AT ABOUT 60,000 MILES THE TRANSMISSION STARTED SHIFTING HARD FROM FIRST TO SECOND GEAR. THE CHECK ENGINE LIGHT STARTED COMING ON INTERMITTENTLY. WHEN THE ENGINE CODE WAS CHECKED IT WAS THE 1870 TRANSMISSION SLIPPAGE CODE. AFTER CHECKING ONLINE THERE WERE HUNDREDS OF OTHER CUSTOMERS WITH THE SAME PROBLEM. I TOOK IT TO THE DEALER AFTER THE CONDITION WORSENED AND THE DEALER RECOMMENDED REPLACING THE TRANSMISSION WITHOUT EVEN SEEING THE PROBLEM DUPLICATED. THIS SHOULD HAVE BEEN A RECALL ITEM YEARS AGO. I HAVE HAD TO REPLACE THE ELECTRONIC FUEL PUMP TWICE. ONLINE THERE WERE NUMBERS OF CUSTOMERS WITH THIS SAVE REPLACEMENT PROBLEM. I HAVE AN OLDER VEHICLE THAT HAVE NEVER HAD THE FUEL PUMP REPLACED. *NM
