I own a 2001 infiniti i30 which was purchased in november 2000 from lynnes infiniti in new jersey. except for the problem discussed below, i have been quite pleased with the vehicle. recently i noticed an unusual sound coming from the engine compartment. the sound seemed to be more pronounced at high speeds, above 50 mph. cursory investigation revealed excessive rusting at and around the mounting area for the bracket that secures the base of the radiator. additional investigation revealed that the structural member that serves as the mounting area for securing the radiator's base was completely rusted through (see accompany photographs). consequently a fairly large hole developed at and around the mounting area completely negating the support provided by the structural member. the lack of support at the base of the radiator translated into excessive up/down movement of the engine compartment's hood. the hook's movement is noticeable at low speeds but becomes very pronounced at speeds in excess of 50 mph. at speeds in excess of 50 mph, the hood's vibration can be visibly observed. aside from the rust-through of the respective structural member, the remainder of the vehicle is practically rust free. as such, it quite apparent that the rust-through of the respective structural member might be attributable to deficiencies in the rust inhibiting treatment applied or a lack thereof. *tr
