Toyota is recalling 2.4 million Prius and Prius v vehicles worldwide to fix a problem with the hybrid system’s “limp home” mode.
The Prius and Prius v are designed to enter limp mode, also called fail-safe mode, when the hybrid systems have faults. Toyota says the recall is necessary because the cars can fail to enter limp mode as intended when the hybrid systems have problems.
Instead of limping home the cars will suddenly lose power and stall out. Toyota insists that power steering and braking will still work, but even with those systems on a stall at high speeds can be very dangerous.
If “limp home” problems sound familiar, you may be thinking of recalls made in 2014 and 2015 for similar problems. Toyota says previous recalls did not anticipate this new condition remedied with this recall. Geez.
The fix is a simple software update. Let’s hope it’s the last one needed.
