Toyota says in rare cases the vehicles might fail to enter a "failsafe" driving mode, lose power and stall. Power steering and braking would continue to work but a stall at a fast speed could increase risks of a crash.
"This recall provides a remedy to address a new condition in the vehicles involved in the previous recalls announced in February 2014 and July 2015. The previous recalls did not anticipate this new condition remedied with this recall," said Toyota.

To address this issue, Toyota dealers will update the software for all involved vehicles, at no charge. Toyota says it will notify the involved customers once the software update is available.
To check a car's recall status, visit Toyota's website or the NHTSA site and enter your Vehicle Identification Number (VIN).
