Symptoms
Delayed or missing throttle response, or a clunk into first, when accelerating from a rolling stop. Owners say it's worse in Sport and Sport+ modes.
The fix, step by step
- As an interim fix until Lexus updates the software, owners set the pre-collision system (PCS) to its minimum distance using the screen in front of the driver; turning PCS off also works but loses a safety system.
- Some use Carista to keep the PCS setting across restarts (and to quiet the ventilated-seat fans).
- Make sure any software recall is done first.
Tools & part numbers
- None, or an OBD-II dongle with Carista.
