I currently own a 2020 Toyota Rav 4. About two weeks ago I got a notification on my car saying "Engine Maintenance Required" i had taken my car to Toyota wondering what the problem was. They informed me it it the coolant bypass valve without hesitation. This is going to cost me more money than I want to spend. To make the situation better the parts needed are on back order for almost two weeks. The fact this is a common problem right now and there is no Recall is unacceptable. You are causing thousands of customers to spend an unnecessary amount of money and wait weeks just to get the correct parts to fix the situation. There is currently a lawsuit against Toyota because of this issue. There needs to be a recall immediately.

Coolant Flow Valve failure at 89,000 miles. It was replaced at Toyota dealership so the faulty valve is not available. My safety was compromised by an impossible to delete dashboard message which obscured the speedometer. The only way to delete the message was to have Toyota dealership fix part and clear code. Other safety concerns would be further engine damage if this part, which is known to be extremely prone to failure, is not repaired. This Coolant Flow Valve failure was indeed confirmed by the Toyota Dealership who also stated it is a very common issue with these 2020 RAV4 models. After completion of the repair the Toyota Dealership did complete a passing inspection of my RAV4 vehicle. The aforementioned warning on the dash appeared around 89,000 miles, no prior problems or symptoms noted.

A message light is shown stating "Engine Maintenance Required. Visit your dealer." Upon inspection from the dealer, it is a problem with the coolant bypass valve. The service men expressed concern for the heat regulation of the engine and things related to the coolant. This seems to be an extremely common problem with other Toyota RAV4s after looking it up online. Given the extent of the issue, this seems warranted to issue a recall for this part.
