Tesla Inc is recalling 15,000 Model X SUVs in North America because of a potential issue that can lead to a loss of power steering assist which will make steering harder and increase the risk of a crash.
In a statement, the National Highway Traffic Safety Administration (NHTSA) and Transport Canada stated, the aluminum bolts that attach the electric power steering gear assist motor to the gear housing may corrode and break causing a reduction or complete loss of power steering assist.
The recall applies to the 2016 model year of Model X vehicles.
Tesla said the issue does not affect vehicles built after 2016.
In March 2018, Tesla had issued a similar recall for 123,000 Model S vehicles worldwide built before April 2016, and had called for replacing steering assist motor bolts.
There are no known crashes or injuries associated with the Model X recall, said the NHTSA.
The recall covers 14,193 U.S. vehicles and 843 in Canada.
“Tesla will arrange for the replacement of the mounting bolts and will also replace the steering gear if needed,” said Transport Canada.
Tesla said it has “observed excessive corrosion on the bolts that attach this component to the steering gear in affected Model X vehicles” and in the most part, in areas with very cold climates that use road salts. If the bolts fail it would require “more force to turn the steering wheel, especially during low speed parking maneuvers,” said Tesla.
Tesla went on to add, drivers can continue to operate their Model X SUVs before the issue is addressed. It will contact owners to schedule appointments when parts are available.
Tesla will also apply a corrosion-preventative sealer in all affected Model X vehicles to account for the possibility that vehicles may later be used in cold climates.
Tesla did not respond to a request for comment.
