“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)…”

“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 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.”
