WASHINGTON, D.C. -

The National Highway Traffic Safety Administration shared details about Toyota and Chrysler recalling more than 42,000 U.S. vehicles combined in separate cases.

Starting with Toyota’s recall, NHTSA indicated that the automaker is recalling five different vehicles from the 2008 through 2011 models years to address the tire pressure monitoring and regulating systems. The specific models include FJ Cruiser, Land Cruiser, Sequoia, Tacoma and Tundra.

The 22,000 units affected by this Toyota recall stem from federal officials saying the units failed to comply with safety standard No. 138. Officials believe the tire pressure monitoring systems were not re-calibrated correctly and therefore do not start illuminating the low-tire pressure warning lamp at the required minimum activation pressure.

NHTSA contends that failure to warn of tire deflations is non-compliant with safety standard No. 138, leading to tire failure and increasing the risk of a crash.

The administration noted franchise dealers have been instructed to re-initialize the tire-pressure monitoring system on these Toyota models.

NHTSA said Toyota had not yet approved an owner notification schedule connected to this recall, according to a posting Friday to the NHTSA website.

Details of Jeep Wrangler Recall

Moving on to Chrysler, NHTSA explained that the automaker is recalling a total of 20,459 Jeep Wranglers from the 2010 and 2011 model years. The recall is to correct a degradation of the fastener torque for various front and rear axle attachments to the chassis module.

Officials fear if the issue is not corrected, it could result in noise or ultimately in deterioration in steering and handling characteristics. Should steering and handling be reduced, NHTSA said the loss of directional control could increase the risk of a crash.

Chrysler is instructing its franchise dealers to re-torque all 19 fasteners to the maximum residual torque values.

The automaker expected to begin the recall this month. Owners of potentially effected vehicles can contact the company at (800) 853-1403.
