Toyota has built a reputation for quality and problem-free vehicles, but has come under criticism recently for the number of recalls and other problems it has suffered. This is the second time in two years that the company has recalled trucks for faulty ball joints. The first recall in 2005 involved more than 750,000 Tacomas, 4Runners, Tundras and Sequoias from the 2001-2004 model years because of a similar problem. Last year, Toyota recalled more than 1 million vehicles spanning most of its range for a variety of problems, tarnishing the company’s reputation for reliability.
