What 14 owners told NHTSA about the 2018 Chevrolet Express Passenger 3500 15 Pass

WHILE PULLING A VARIETY OF 3 DIFFERENT TRAILERS, THE INTEGRATED TRAILER BRAKE CONTROL DOES NOT PROPERLY SEND OUTPUT TO THE TRAILER BRAKES. THIS CAUSES THE TRUCK (TOW VEHICLE) TO DO ALMOST ALL OF THE BRAKING WORK ON ITS OWN. ON MULTIPLE OCCASIONS I'VE HAD THE ANTI LOCK BRAKES ACTIVATE ON THE TRUCK WHILE TRYING TO STOP AT A TRAFFIC LIGHT BECAUSE I WASN'T GETTING ADEQUATE BRAKING FROM THE TRAILER DUE TO THE INTEGRATED TRAILER BRAKE CONTROL FAILING TO SEND ADEQUATE POWER TO THE TRAILER BRAKES. THE GAIN ON THE TRAILER BRAKE CONTROL WAS SET PROPERLY FOR THE LOAD BEING PULLED ON THE TRAILER AND THE GROSS COMBINATION WEIGHT OF THE TRUCK/TRAILER/LOAD DID NOT EXCEED THE RATED CAPACITIES OF THE TRUCK OR TRAILER. THE TRUCK HAS BEEN TO 2 DIFFERENT CHEVROLET DEALERS AND BOTH OF THEM HAVE TRIED BLAMING THE TRAILER OR THE OPERATOR. I HAVE SHOWN BOTH DEALERS THAT THE TRUCK DOES IT WITH A VARIETY OF DIFFERENT TRAILERS AND PROVEN THAT IT'S NOT THE TRAILER. I HAVE MY CLASS A CDL AND HAVE BEEN PULLING TRAILERS WITH BRAKE CONTROLLERS FOR 20 YEARS. THIS INSTANCE HAPPENS AT ALL DIFFERENT SPEEDS OF TRAVEL WHILE DRIVING, WHETHER IT BE 5 MPH OR 65 MPH OR ANYWHERE IN BETWEEN. ALSO, WHILE SITTING STILL AT A TRAFFIC SIGNAL, THE TRUCK PUTS NO BRAKING POWER TO THE TRAILER WHICH IS HORRIBLE WHEN YOU ARE SITTING ON ANY KIND OF SLOPED GRADE. FROM A COMMERCIAL DRIVER STANDPOINT, THIS TRUCK DOES NOT IN ANY WAY SHAPE OR FORM PASS A DOT SAFETY INSPECTION DUE TO THIS ISSUE. THE TRUCK HAS ROUGHLY 37,000 MILES, IS WELL TAKEN CARE OF, AND IS FLEET MAINTAINED. THE ATTACHED PHOTO IS WHILE SITTING STILL WITH A LOADED GOOSENECK TRAILER HOOKED TO THE TRUCK.
