"This is an update regarding the revised flat-towing procedure for 2010-2017 Chevy Equinox and GMC Terrain vehicles with 4-cylinder engines. The revised procedure, outlined in GM service bulletin 17-NA-348, was developed to eliminate the wobble that sometimes occurs when the vehicle is flat towed. The owner of a 2016 Chevy Equinox has reported that after following the procedure in service bulletin 17-NA-348, he has noticed the smell of burning brake pads.  This has happened a number of times. The owner checked his supplemental braking system, which is actuated by the hydraulics on the hitch, and it was loose and not operating the brakes. He said the smell does not occur when he follows the original flat-towing procedure, as outlined in the owners manual.\n \n\n\n\tI notified GM about this, and today (January 29) I received this response:  \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\tI will of course pass along information as it becomes available.\n \n"
