While driving my 2005 Nissan Altima in active traffic with my [XXX] child, the vehicle suddenly stalled without any warning. The engine completely shut off while in motion, creating an immediately safety hazard in live traffic conditions. Immediately after the stall, I observed oil leakage and smoke entering the cabin. The vehicle became inoperable and we were stranded roadside. This failure is consistent with a known defect involving the crankshaft position sensor and engine control system addressed in NHTSA Campaign 07V-527, which describes sudden engine stall without warning due to sensor signal interruption. Although my vehicle previously received recall-related service, this incident suggests the prior remedy did not prevent recurrence of the defect. Sudden engine shutdown while driving in traffic Loss of vehicle power without warning Smoke entering passenger cabin Risk of crash involving child passenger Request: I am requesting that NHTSA: Review this incident for potential recall remedy failure Investigate whether this represents recurrence of a known defect Determine whether additional corrective action is needed for this vehicle population INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
