Recalls and investigations

One recall on the engine covers the 2020 model year. A recall on the same system isn't always the same failure, so read the defect text.

Engine And Engine Cooling

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020 Toyota Avalon Hybrid, Camry, Camry Hybrid and Lexus ES300h and 2019-2020 RAV4 and RAV4 Hybrid 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.

Risk and remedy
Risk: 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.
Remedy: 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. Owners may contact Toyota customer service at 1-888-270-9371 or Lexus at 1-800-255-3987. Toyota's number for this recall is 20TA04. Lexus' number for this recall is 20LA02.

What owners wrote

“I was driving and out of nowhere this warning came on engine maintenance required, and this now a normal maintenance required that means an oil change. The problem with this warning is the coolant bypass valve, and I’m not the only one with this issue, my car has only 32100 miles only, this a ridiculous for a new car. Plus it seem that this issue only comes on with tha A/C on”

“Coolant Bypass Valve failure at 41K miles. Confirmed by dealership. "Engine Maintenance" warning light came on before taking to dealership.”

“The coolant bypass valve is defective on a 3 year old single owner, well maintained under 50,000 miles vehicle. This is a wide spread and known issue for Toyota which can result in engine overheating, causing potentially unsafe situations to occur for the driver. This can also severely damage the engine.”

“The Coolant flow control valve is malfunctioning. This was diagnosed by a Toyota dealer. My car is 3 years old and has 56k miles. Upon doing more research, a lot of people have complained that the same things are happening to their vehicles as well. To my understanding, this is not something typical for a car as young as mine.”

Should you keep driving it?

This page can't tell you that. 0 of 153 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
