On [XXX], I was driving our 2017 Silverado 2500HD LT 6.6, with my family in Ohio when the trailer brake controller error started flashing on the dash and would not shut off, go silent nor correct itself. It almost caused an accident initially because it was distracting me by making me look down to READ the message. Then we were almost in a dozen accidents as we were traveling too slow for conditions, unable to get off the highway safely, and issues with steering and braking. In 10 minutes, the error sounded 50+ times. We were towing a 36’ 5th wheel trailer suddenly STABILITRAC also kicked on, REDUCED POWER (another message to look down and read), the engine started running so rough (another issues to look down at the gauges) that I thought the engine had blown. We were not in a safe place to pull over and power was cut dropping our speed from 70 to 45 in a 70 zone. Just after going up the hill, we had to continue down other side which we discovered that the trailer brakes were NOT operational. As we were burning our truck brakes going down the other side. The only reset is to shut off the key (which would lock the steering wheel, lose power steering and power brakes while driving). When STABILITRAC appears vital drivers data is BLOCKED. We removed the trailer brake fuse and the trailer battery charger fuse, but the TRAILER BRAKE CONTROLLER messages continued. Even with the trailer disconnected the the messages continued. The trailer brake wire under the truck had exposed wires. Did the exposed wire cause other systems to malfunction? 1.Are the defective wiring harness(es) causing other systems to fail too, and/or can cause electrical fires? 2.Defective trailer braking unit needs to give one warning and STOP. This defect poses a serious issue for anyone towing (or not). 3.STABILITRAC is going to KILL someone because I believe it already has killed. If STABILITRAC throughs the right code it WILL shut down the engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

JUST RECEIVED A LETTER FROM GENERAL MOTORS WITH A PAGE THAT IS TO BE INSERTED INTO MY OWNERS MANUAL. THE ISSUE IT PURPORTS TO SOLVE IS THAT THE MANUAL STATES THAT IF THIS TRUCK HAS FORWARD COLLISION ALERT, IT ALSO HAS FORWARD AUTOMATIC BRAKING & INTELLIGENT BRAKE ASSIST. THAT IS INCORRECT & THIS ALERT IS TO CORRECT THAT ERROR. BUT, THE MANUAL INSERT PROVIDED IS NONSENSE. IT HAS NO PAGE NUMBER TO TELL US WHERE TO INSERT THE NEW PAGE; THERE ARE 2 SECTIONS RELATING TO THIS IN THE MANUAL. THE INSERT ALSO SAYS IT ONLY APPLIES TO 1500 SERIES TRUCKS. MINE IS A 2500 SERIES. SO WHY SEND THIS. GM HAS MESSED THIS UP AND IT SEEMS TO ME YOU NEED TO CALL THEM ON IT TO PROVIDE CORRECT INSERTS FOR THE 2 MANUAL AREAS TO WHICH IT APPLIES. THAT SHOULD INCLUDE CORRECT INFORMATION AND PAGE NUMBERS. OTHERWISE THE MATERIAL I RECEIVED IS IRRELEVANT TO CORRECTING THE ORIGINAL ERROR. I AM A RETIRED GOVERNMENT PERFORMANCE AUDITOR, SO SERIOUS MISTAKES IN CORRECTING PROBLEMS CONCERN ME.

MY FAMILY AND I WERE WOKEN AT 3AM EARLY JANUARY TO A VEHICLE ALARM. TURNS OUT THE TRUCK HAD STARTED FIRE. LUCKLY THE ALARM WAS AUDIBLE LONG ENOUGH TO WAKE US. BY THE TIME I HAD REACHED THE KEYS, IT HAD STOPPED. A PEEK OUT THE WINDOW SHOWED A CULPRIT I HADN'T ANTICIPATED. INSPECTORS FOUND THE SOURCE IN THE LOCATION OF THE BLOCK HEATER. NO WIRING CHARED BEYOND THE FRONT OF THE TRUCK. CONTINUED CONTACT WITH GM HAS YET TO REVEAL ANY INFORMATION. I LOVED THE TRUCK AND WOULD LIKE TO KNOW IF THE ISSUE IS SOMETHING THAT MAY KILL US NEXT TIME. WITH THE RECALL OF FORDS BLOCK HEATER ISSUES, I FEEL THAT THIS SOMETHING THAT SHOULD BE ANSWERED.
