2019 Toyota Rav 4 Hesitation On Acceleration From a Slow Roll or Rolling Stop


Some 2019 model year RAV4 vehicles may exhibit a hesitation on acceleration from a slow roll or rolling stop under the following conditions.
* 6 mph or below
* Immediately following a 3 – 1 downshift
* Less than 40% accelerator pedal application

The Engine Control Module/ECM (SAE Term: Powertrain Control Module/PCM) logic has been modified to reduce the potential for hesitation. Follow the Repair Procedure in bulletin T-SB-0107-19 Revision 1 to update the ECM calibration.

See T-SB-0107-19 Rev1

This Service Bulletin requires a drive pattern to be performed after the calibration update is completed. The proper execution of these drive patterns is necessary for the drivability updates to take effect. Refer to the Repair Procedure for drive pattern details.

This repair is covered under the Toyota Federal Emission Warranty. This warranty is in effect for 96 months or 80,000 miles, whichever occurs first, from the vehicle’s in-service date
