"FMCA was notified November 1 that GM engineers have developed a revised flat towing procedure for 2010 through 2017 Chevy Equinox and GMC Terrain vehicles equipped with 4-cylinder engines. GM developed the new procedure to eliminate the wobble that sometimes occurs when flat towing these vehicles behind a motorhome.\n \n\n\n\tGM officials said a service bulletin has been distributed to GM dealerships advising them of the revised towing procedure. The service bulletin says this about the wobble, or instability: “This condition may be caused by fuse 32 being removed from the instrument panel fuse block as outlined in the owners manual.”\n \n\n\n\tIn the revised procedure, it is no longer necessary to remove fuse 32. However, fuse 16 must be removed. Engineers determined that these changes should keep the vehicle’s electric power steering activated during flat towing. Another important aspect of the revised procedure: An auxiliary battery charger must be installed to prevent the battery in the Equinox/Terrain from losing its charge while the vehicle is being towed.\n \n\n\n\tPlease read closely the attached service bulletin, which details the complete revised flat towing procedure for 2010 to 2017 Equinox/Terrain.\n \n\n\n\tAs for the 2018 Equinox: GM officials say that because its electrical architecture is different, it is not necessary to pull any fuses. However, just as with 2010-2017 models, a charger will be necessary to keep the towed vehicle’s battery charged. The current owners manual for the 2018 Equinox will be revised to reflect the need for a charger, GM officials said.\n \n\n\n\tThe 2018 GMC Terrain is not flat towable.\n \n\n\n\tIn July, Larry Milhalko, GM’s crossover vehicle performance manager, told FMCA that the first step in developing a fix was to replicate the wobble during testing. He said this week that although testing encompassed a variety of conditions and scenarios, engineers were unable to replicate the wobble. Nevertheless, he said, “we’re pretty confident” that the revised towing procedure will solve the wobble problem. “We think we have a good solution.” \n \n\n\n\tFMCA will continue to follow this issue. If Equinox/Terrain owners experience the wobble when using the revised flat towing procedure, contact John Johnston at jjohnston@fmca.com.\n \n\nEquinox Terrain revised flat towing.docx \n"
