1998 Infiniti QX4 RecallsRust May Form on the Strut Tower Housing
In areas where winter road salt is used, a mixture of snow/water and salt may enter an assembly location hole in the upper strut housing. This corrosive mixture can collect on the mating surface of the strut housing panel and the inner hood ledge assembly; over time, this can cause rusting of the strut tower housing. The rust can weaken the housing, causing it to crack and pull away from the inner hood ledge assembly. This can lead to grinding noises and increased steering effort, which, if severe enough, can cause the steering column to break. This would result in a loss of steering control, increasing the risk of a crash. Dealers will inspect the strut housing and repair the vehicles as necessary. An interim notification letter should be mailed to owners prior to May 16, 2011.
