LIMITED SLIP DIFFERENTIAL CAUSING LOSS OF CONTROL ON ICY ROADS. I RECENTLY LOST CONTROL OF MY TRUCK WHILE DRIVING ABOUT 45MPH ON AN ICY HIGHWAY IN BOULDER, CO. BECAUSE THE LOSS WAS SO INSTANTANEOUS RESULTING IN THE TRUCK SPINNING 90 DEGREES TO THE DIRECTION OF TRAVEL, I QUESTION IF THE LIMITED SLIP FUNCTION WOULD CAUSE POWER TO TRANSFER TO A WHEEL IF IT SUDDENLY HIT DRY PAVEMENT, WHILE THE OTHER WHEEL WAS SPINNING ON ICE, RESULTING IN A SPIN OUT. THIS IS ONLY MY THEORY BUT WITH 57 YEARS OF DRIVING EXPERIENCE AND THE FACT THAT I HAVE HAD WEIRD EXPERIENCES WITH LIMITED SLIP DIFFERENTIALS IN THE PAST I THOUGHT MY THEORY MAY HAVE SOME VALIDITY. MY CONCERN IS THAT THERE ARE MILLIONS VEHICLES WITH LIMITED SLIP DIFFERENTIALS ON THE ROAD AND IF MY THEORY IS VALID, PERHAPS MANY ACCIDENTS ARE BEING CAUSED BY THIS OPTION (WHICH CAME AS PART OF A PACKAGE WHEN I PURCHASED MY TRUCK). *TR

COMPLAINT REPORTS ALLEGE POOR WELD QUALITY AND/OR BENDING OF THE SUBJECT VEHICLE ORIGINAL EQUIPMENT TRAILER HITCH RECEIVER.THE AGENCY'S INVESTIGATION INCLUDED ANALYSIS OF MANUFACTURER AND AGENCY INCIDENT REPORTS, REVIEW OF POLICE REPORTS, ANALYSIS OF THE AGENCY'S FATAL ANALYSIS REPORTING SYSTEM, A VEHICLE OWNER SURVEY, INSPECTION OF TOW VEHICLES/HITCHES AND ANALYSIS OF FAILED PARTS.INCIDENTS OF WELD FAILURE WERE RARE AND ASSOCIATED WITH VERY LOW-SPEED DRIVING (TURNING, BACKING AND SUDDEN STOPPING).INCIDENTS OF BENDING WERE ASSOCIATED WITH IMPROPER TRAILER HITCH ADJUSTMENT OR OVERLOADING. A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL MONITOR THIS ISSUE AND RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.SEE DOCUMENT SEARCH FILE FOR ADDITION INFORMATION.
