NHTSA Complaint #11103457 — 2009 TOYOTA TACOMA

DRIVESHAFT AND UNIVERSAL JOINT PROBLEM. TOYOTA HAS ISSUED A "WARRANTY ENHANCEMENT - ZH2" FOR THIS PROBLEM, BUT IT SHOULD BE A FULL RECALL, AS THE CONDITION CAN LEAD TO SUDDEN DRIVESHAFT FAILURE, LOSS OF VEHICLE CONTROL, AND DEATH. THE PROBLEM APPEARS TO ALSO EXTEND TO THE CENTER BEARING AND POSSIBLY THE DRIVESHAFT ITSELF, AS I TOOK MY TRUCK IN FOR SERVICE UNDER WARRANTY, AND STILL HAVE VIBRATION ISSUES EVEN AFTER THE WARRANTIED PARTS (AND CENTER SUPPORT BEARING AT SIGNIFICANT EXTRA COST) WERE REPLACED. THIS VIBRATION BEGINS AROUND 40 MPH AND INCREASES THROUGH 60 MPH. I AM CONCERNED THAT THE VEHICLE IS UNSAFE TO DRIVE AND MAY SUSTAIN A SUDDEN DRIVESHAFT FAILURE FROM IMPROPER REMEDIATION OF THIS ISSUE UNDER THE ZH2 CAMPAIGN.
