In other big-truck new, a pension fund reportedly is suing International-maker Navistar over what it calls misleading statements made about diesel engine emissions-control technology later abandoned by the company.
The Norfolk Country Retirement System says former CEO Dan Ustian and current Chief Financial Officer Andrew Cederoth concealed troubles Navistar was having meeting clean-air requirements with an exhaust-gas recirculation system on its diesel engines, Bloomberg reports.
Navistar was banking on the technology to meet U.S. Environmental Protection Agency emissions standards but it failed to do so, causing the manufacturer to pay non-compliance fines before switching to selective catalytic reduction technology, a urea-based after-treatment system used by competitors.
The pension plan is requesting unspecified compensation for investors holding Navistar stock between June 9, 2010, and August 1, 2012.
Separately, Navistar has ceased production at its Garland, TX, plant. The facility will close for good May 31, displacing 900 workers, says the website of Dallas TV station NBCDFW.
The Garland closure was announced by Navistar last fall as part of a move to consolidate production in Ohio and Mexico.
