According to the San Antonio Express, Toyota is facing another probe by the National Highway Traffic Safety Administration - on the heels of its unprecedented recall of potentially accident-causing floor mats. This time, the NHTSA is looking into rust and corrosion defects on almost 220,000 Toyota Tundras. The agency has received 20 complaints that “related to spare tire separation and brake system failures as a result of severe frame corrosion.”

The investigation revolves around the model years 2000 and 2001, and may be related to a similar probe relating to 1995-2000 Tacomas. Apparently, the supplier of the 1.4 million defective Tacoma frames also supplied the Tundra frames, which allegedly can’t stand up to severe northeastern winters and road salt. Stay tuned as the investigation progresses.
