Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

THEY COULD BE POSSIBLY DESIGNED FOR STATIONARY USE IN A PERFECT ENVIORMENT BUT NOT FOR MOVING VEHICLES, I CANNOT SAFELY DRIVE THIS VEHICLE AT NIGHT, I FEAR NOT ONLY FOR MYSELF BUT FOR OTHER PEOPLE ON AND NEAR THE PATH OF THIS VEHICLE. MY MIND IS CLEAR, THERE ARE MANY BLOWING THE WHISTLE.

NHTSA ID 11500249 · filed Jan 5, 2023

I HAVE BEEN HAVING A PROBLEM WITH THE TRAILER BRAKE CONTROLLER ON MY K3500 TRUCK. RECENTLY THE MESSAGE "CHECK TRAILER WIRING" HAS BEEN COMING ON FREQUENTLY. AT THE SAME TIME, THE BRAKING CONTROLLER SHUTS OFF POWER TO THE TRAILER BRAKES. THIS HAS RESULTED IN A VERY UNSAFE CONDITION, ESPECIALLY WITH A TRAILER THAT WEIGHS OVER 14,000 POUNDS. THIS HAS BEEN GOING ON FOR 6 MONTHS NOW. REPEATED ATTEMPTS BY BOTH THE GMC DEALER AND THE TRAILER DEALER HAVE FAILED TO RESOLVE THE PROBLEM. I HAVE BEEN TOLD, BY THE DEALER, THAT THE PROBLEM STARTED APPROXIMATELY WITH THE 2014 MODELS. THE BRAKE CONTROLLER HAS BEEN UPGRADED, AND MADE MUCH MORE SENSITIVE TO SLIGHT DEVIATIONS IN THE TRAILER SYSTEM, CAUSING THE CONTROLLER TO "SHUT OFF" SO TO SPEAK. WHILE THIS WOULDN'T BE A BIG ISSUE NORMALLY, WHEN IT SHUTS OFF, YOU LOSE ALL BRAKING ABILITY TO THE TRAILER RESULTING IN AN UNSAFE CONDITION. THERE IS NO WAY TO OVERRIDE THIS AND ACTIVATE THE BRAKES. WHAT SEEMS TO BE HAPPENING IS A VERY SLIGHT DEVIATION IN THE RESISTANCE IN THE TRAILER BRAKE SYSTEM (BY 1 OHM OR LESS) AND THAT CAUSES THE "SHUTDOWN" IN THE CONTROLLER. TRAILER BRAKES WOULD WORK, IF THEY COULD GET POWER. BUT, THE CONTROLLER HAS SHUT DOWN, SO NO POWER. MYSELF (AND THE TRAILER SHOP) HAVE BEEN CHECKING THE INTERNET AND FINDING THAT THIS IS NOT AN ISOLATED INCIDENT. IT APPEARS TO BE HAPPENING WITH ALL THE BIG THREE MANUFACTURER TRUCKS, SINCE ABOUT 2014. PEOPLE HAVE BEEN COMING UP WITH SOME RATHER "CREATIVE" WAYS AROUND THIS, IN SOME CASES ELIMINATING THE ORIGINAL SYSTEM ENTIRELY. THIS IS JUST NOT ACCEPTABLE. AGAIN, THIS "NEW SYSTEM THE BIG THREE ARE PUTTING IN IS FAR WORSE THAT THE OLD, SIMPLY BECAUSE IT HAS NO ROOM FOR FORGIVENESS IN A TRAILER SYSTEM THAT MIGHT WORK OTHERWISE, BUT HAS A SLIGHT DEVIATION IN WHAT IS CONSIDERED "ACCEPTABLE" TO THE CONTROLLER. AT THE VERY LEAST, THERE SHOULD BE A FAIL SAFE METHOD.
