1999 GMC Sierra 1500 Owner Complaints

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

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.

WHILE OPERATING THE VEHICLE AT APPROXIMATELY 45 MPH, I WAS APPROACHING AN INTERSECTION WHEN I APPLIED THE BRAKES TO SLOW THE VEHICLE. ONE OF THE REAR BRAKE LINES BURSTED CAUSING ME TO HAVE TO ABRUPTLY PUMP THE BRAKE PEDAL TO STOP THE VEHICLE. VERY DANGEROUS SITUATION AS A MARKED SHERIFF'S VEHICLE WITH ITS EMERGENCY LIGHTS AND SIREN ACTIVATED WAS TRAVELING AT A HIGH RATE OF SPEED ON THE INTERSECTING HIGHWAY THAT I WAS APPROACHING. THIS IS A KNOWN AND PREVALENT PROBLEM THAT EXISTS WITH GM TRUCKS AND GM IS WELL AWARE OF THE ISSUE BUT DENIES FAULTY PARTS.

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.

WHEN COMING TO A STOPLIGHT, I APPLY THE BRAKES AND THE PEDAL GOES DOWN MORE THAN IT SHOULD, BUT I GET STOPPED. WHILE HOLDING THE BRAKE AND WAITING FOR THE LIGHT TO CHANGE THE BRAKE PEDAL GOES SLOWLY TO THE FLOOR. NEXT, I PULL INTO A PARKING LOT AND GET STOPPED. I PUT THE TRUCK IN PARK AN LOOK UNDER THE HOOD AT THE BRAKE MASTER CYLINDER, NO FLUID LEAKS, THEN I C LOOK AT EACH WHEEL, NO FLUID LEAKS. I GET TURNED AROUND AND HEAD HOME BECAUSE I KNOW SOMETHING IS WRONG. DRIVING HOME THE BRAKE PEDAL IS SOFT. I'M SOON HOME AND I PARK THE TRUCK BUT WITH THE MOTOR STILL RUNNING, I SLOWLY DEPRESS THE BRAKE PEDAL, IT GOES SLOWLY TO THE FLOOR, NEXT TIME I DEPRESS THE BRAKE PEDAL IT GOES TO THE FLOOR IN A SPLIT SECOND. I GET OUT AND INSPECT UNDER THE TRUCK. I SEE BRAKE FLUID LEAKING FROM THE LINES RUNNING DOWN THE FRAME RIGHT UNDER THE DRIVERS DOOR.

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
