I just did a search on this problem on the NHTSA website and there is total of 15 complaints between model years 2004 & 2005. It only took 14 to open an investigation on the alternator on the Murano and now the Murano has another one open due to punctures in the fuel tank from road debris. That one only took 4 complaints.
I don't see why NHTSA wouldn't open one soon on this problem with the Titan.

Call the DOT Vehicle Safety Hotline at 1-888-DASH-2-DOT (1-888-327-4236) and a NHTSA representative will record your complaint information.
Your complaint information will be entered into NHTSA's vehicle owner's complaint database and used with other complaints to determine if a safety-related defect trend exists.
* If a safety-related defect exists in a motor vehicle or item of motor vehicle equipment, the manufacturer must fix it at no cost to the owner. Your complaint is the first step in the process.
* Government engineers analyze the problem. If warranted, the manufacturer is asked to conduct a recall. If the manufacturer does not initiate a recall, the government can order the manufacturer to initiate a recall.
* We do not have to receive a specific number of complaints before we look into a problem. We gather all available information on a problem. Your complaint is important to us.
