The Ford recall affects certain 2014 model year F-150 trucks. Downshifting can cause rear tires to slide or lock up until the truck slows down, which could cause drivers to lose control of their vehicles and increase the risk of a crash.

The F-150 has been the top-selling truck in the United States for decades.

In documents posted Tuesday by the National Highway Traffic Safety Administration, Ford said a signal loss between the transmission sensor and powertrain control module was responsible for the problem.

NHTSA regulators relayed two injury complaints related to the transmission issue to Ford, company spokesperson Maria Buczkowski said.

Ford expects a fix to be available in the third quarter of this year, Buczkowski said. Owners can expect notification letters in the mail after July 1, NHTSA documents said.

F-150 owners who experience the downshifting problem before the wider fix is available can take their vehicles to dealers for service, Buczkowski said. They also can use mobile service or pickup and delivery for repair, Buczkowski said.

An excessive electrical current could cause the front windshield wiper to fail on more than 11,000 Cybertrucks, Tesla said in NHTSA documents.

The other recall of Cybertrucks involves a piece of the trunk bed trim that could loosen and fly off, becoming a road hazard for others. The adhesive that holds the trim piece may have been installed improperly, Tesla said in NHTSA documents.

The company plans to replace wiper motors and rework the trim pieces to stay on. Cybertruck owners will receive notification letters related to both recalls starting Aug. 18.

Tesla is not aware of any crashes or injuries related to the wiper and trim issues, it said in NHTSA documents.

Tesla has issued four Cybertruck recalls since the vehicle went on sale in November, including a recall of about 3,800 vehicles in April over risk of a jammed accelerator pedal.

Although the number of Cybertrucks on the road remains relatively low compared with more established truck brands, the Tesla vehicle has drawn an outsize amount of attention for its design.
