NHTSA Complaint #10138670 — 2004 NISSAN QUEST

I HAVE A HARMONIC VIBRATION FELT THROUGH THE STEERING WHEEL ON MY 04 QUEST S. OVER LONG DISTANCES, THE SHAKING CAUSES NUMBNESS OF THE HANDS. THE DEALER HAS ATTEMPTED TO RESOLVE THE PROBLEM THREE TIMES BEFORE ULTIMATELY DECLARING THAT THIS IS THE NORMAL OPERATING CONDITION OF THE VEHICLE. I BELIEVE THAT THIS IS COMPLETELY UNACCEPTABLE. THIS IS A LOG OF WHAT WAS DONE TO RESOLVE THE ISSUE: MONTH 22 IN SERVICE: 28-JUN-05 @ 29,972 MILES - REPLACED ALL FOUR GOODYEAR EAGLE LS 225/65R16 TIRES AS PER DEALER RECOMMENDATION. REASON: WORN. (PART# OETIR-06482). THIS IS WHEN THE SHIMMY EFFECT BECAME OBVIOUS. THE PROBLEM WAS REPORTED TO THE DEALER. MONTH 23 IN SERVICE: 15-AUG-05 @ 32,305 MILES - RE BALANCED ALL 4 TIRES. NO EFFECT. MONTH 23 IN SERVICE: 22-AUG-05 @ 32,727 MILES - REPLACED FRONT TWO TIRES. TIRES ROAD FORCE BALANCED. NO EFFECT. MONTH 24 IN SERVICE: 7-SEP-05 @ 33,101 MILES - RE BALANCED ALL WHEELS AND CHECKED ROAD FORCE. CHECKED FRONT HUB RUNOUT. ADJUSTED STEERING RACK FORCE. CLEANED ALL MATING SURFACES BETWEEN HUB AND ROTOR AND ROTOR AND WHEEL. DEALER CLAIMS ROAD TESTED OK. NO EFFECT. MONTH 25 IN SERVICE: 28-SEP-05 @ 33,985 MILES - ROAD TEST. DEALER STATES NORMAL OPERATING CONDITION FOR VEHICLE. I HAVE REPORTED THE ISSUE TO NISSAN CONSUMER AFFAIRS (CASE # 5066744) BUT THEY REFUSE TO ACCEPT RESPONSIBILITY FOR THE ISSUE BY STATING THAT IT IS A NORMAL OPERATING CONDITION. *NM
