NHTSA recall 20V064000

What's wrong: Affects vehicles equipped with 2.5L 4-cylinder engines. Porosity in the engine castings may result in cracks than can allow coolant to leak internally and/or externally.

Why it matters: A coolant leak can cause the engine to overheat and cause a vehicle stall in conventional gasoline vehicles, increasing the risk of a crash. Additionally, for all involved vehicles, the engine may get damaged mechanically, possibly resulting in an engine oil leak, increasing the risk of a fire.

The fix: Toyota will notify owners, and dealers will inspect and replace the engine including the engine block, as necessary, free of charge. The recall began April 3, 2020.
