DETROIT (Reuters) - Ford Motor Co. (NYSE:F) said Monday it would recall about 434,700 vehicles, mainly in North America, due to two separate and unrelated problems.

The company is recalling about 385,750 Escape compact SUVs as rust could cause their subframes and lower control arms to separate, potentially diminishing steering control, it said in an e-mail.

The recall affects model years 2001-2004 sold or currently registered in the United States and Canada.

Ford said the rusting could occur in vehicles used in high-corrosion environments, particularly those areas where salt was used on the roads to melt ice.

The company also said it was calling back about 48,950 model-year 2013-2014 Fusion, Lincoln MKZ, Escape and C-MAX vehicles to replace seat-back frames that did not comply with National Highway Traffic Safety Administration standards.

Some of the frames may have been produced with substandard welds, increasing the risk of injury during collisions, Ford said.
