"This is an update for owners of 2010-2017 4-cylinder Chevy Equinox and GMC Terrain who flat tow the vehicles behind a motorhome..\n \n\n\n\tBACKGROUND: In November 2017, GM issued a revised flat towing procedure, which was outlined in GM service bulletin 17-NA-348 (which is attached). The revised procedure was developed to eliminate the wobble that sometimes occurs when the vehicle is flat towed behind a motorhome. In late January 2018, after an owner reported the smell of burning brake pads when using the revised procedure, GM issued the following statement:\n \n\n\n\t“Unless owners have experienced a wobble with the original procedure – they do not need to switch to the revised bulletin. If they have already switched to the revised bulletin, they can either continue to follow that bulletin, or switch back to the original procedure if experiencing any brake pad smell issues.  The revised bulletin is absolutely safe to follow, however if owners experience the brake pad smell, they should return to the original procedure. GM engineering is currently exploring reasons for why that may be happening.”\n \n\n\n\tUPDATE: According to GM’s engineering team, when the revised flat towing procedure is followed, the brake control modulator (the ABS modulator) is powered off. Therefore it is not possible for the brakes to be applied unless the service brake pedal is being pushed down. Bottom line: the revised towing procedure is not the cause of the brake pad smell.     \n \n\n\n\tCURRENT TOWING RECOMMENDATION FROM GM:  \n \n\n\n\tIf you have never experienced the wobble, continue to follow the original flat towing procedure in the owners manual. If the wobble occurs, switch to the revised procedure in GM service bulletin 17-NA-348 (which requires the Equinox/Terrain battery to be charged during flat towing). Do not \"mix\" procedures; follow either one or the other. Whichever procedure you use, be sure to follow the proper sequence outlined in the instructions.\n \n"
