NHTSA Complaint #10916273 — 2014 CHEVROLET EQUINOX

MOTORHOME MONACO EXECUTIVE 45' TAG AXLE COACH 525HP CUMMINS TOAD CHEVROLET EQUINOX 2014 SUBJECT VEHICLE PURCHASED NEW 2014 NSA TOW BAR, 6000# LIMIT IN EXCELLENT CONDITION SURGE BRAKES BLUEOX BASEPLATE, PROFESSIONALLY INSTALLED IN EXCELLENT SHAPE. WHILE TOWING FOUR DOWN BEHIND MY MOTORHOME, I ENCOUNTERED ROAD CONSTRUCTION. TURNING SLOWLY ON A VERY BUMPY SITE, THE FRONT WHEELS OF THE CAR REFUSED TO FOLLOW THE TRACK OF THE MOHO AND BEGAN A VIOLENT SHAKING MOTION. I HAD TO STOP IN A TRAFFIC LANE ON THE INTERSTATE THEN PROCEED FORWARD AGAIN SLOWLY IN ORDER TO CORRECT THE WOBBLE. IT APPEARS THE ISSUE IS INSUFFICIENT CASTER ON THE FRONT END WHILE BEING TOWED. IT ALSO APPEARS TO ONLY OCCUR WITH THE 4CYL MODEL WITH ELECTRIC STEERING. THE 6CYL MODEL HAS HYDRAULIC STEERING. I HAVE BEEN ABLE TO RECREATE THE WOBBLE IN A SAFE LOCATION. IF IT OCCURS ON THE HIGHWAY IT'S VERY DANGEROUS AS THE VEHICLE COULD SEPARATE FROM THE TOWING VEHICLE. TWO POSSIBLE SOLUTIONS ARE NOT REMOVING THE FUSE RECOMMENDED IN MY MANUAL WHICH WOULD ALLOW THE ELECTRIC STEERING TO BE ENERGIZED. I'M NOT SURE OF ANY OTHER ISSUES THAT MIGHT RESULT FROM THIS PRACTICE. THE OTHER SOLUTION WOULD BE TO BUNGEE CORD THE STEERING WHEEL TO INCREASE PRESSURE ON THE FRONT END. AGAIN, NOT SURE OF CONSEQUENCES. I'M LOOKING FOR A PERMANENT SOLUTION SUCH AS A WIRING HARNESS/JUMPER WHICH WOULD STILL ALLOW THE FUSE TO BE PULLED YET KEEP THE STEERING ENERGIZED. CHRYSLER HAD A SIMILAR ISSUE WITH THE JEEP CHEROKEE. I AM HOPING THE EQUINOX IS SIMILAR IN CONSTRUCTION AND THIS IS A SOLUTION. I'VE BEEN TOWING FOR OVER 40 YEARS WITH 85,000 MILES ON THIS COACH. I LOOK FORWARD TO HEARING FROM YOU. TOGETHER PERHAPS WE CAN SOLVE THIS DANGEROUS CONDITION. I'M NOT ALONE WITH THIS ISSUE AS I HAVE DOCUMENTATION FROM OTHERS WHO'VE EXPERIENCED THE SAME ISSUE.
