Last week I received a recall notice from Toyota canada for our 2020 Rav4h. It includes 2020 Camry, Camry h and 2019 -2020 Rav4 and Rav4 hybrid. Recall says they want to check the engine block casting number to see if it was manufactured incorrectly causing coolant to leak internally and or externally.
If the engine numbers are determined to be involved the dealer is to replace the engine
Edit: I just read on Car and Driver that Toyota is recalling 44,000 vehicles and suspects 250 vehicles to have the manufacturing defect.
Interesting to note they mention the regular gas engine could stall at higher driving speeds without warning. But the hybrids will enter a fail safe driving mode allowing the driver to maneuver the vehicle to a safe location.
