2020 Toyota RAV4

I have a 2020 Toyota RAV4, two weeks ago the following display appear "Engine Maintenance Require, Visit Your Dealer". I attempted to clear it but it cannot be done. I check online for similar issues. I found that the 2019 Toyota RAV4, Camry, Avalon, and Lexus ES300H vehicles have similar issue with the 'coolant bypass valve'. Mine is also a 2.5L 4-Cylinder Engine. I purchase my Rav4 on Feb 24, 2020. My car only has 15,429 miles and a possible fire issue makes me nervous. I also notice than some preselected 2020 RAV4 were added to the recall, but not my RAV. Should I wait till my engine cracks or the cooling system fail?

Got an engine maintenance required alert, took to Toyota and they advised the coolant bypass valve needs to be replaced at just 38,000 miles. Googled this and found out many 2020 RAV4 with the same issue at just under 40,000 miles. Also a common issue is the voltage being low and we already had to get the battery replaced once and still get alerts of it being low after replacement. Have to pay today $765 for the coolant bypass to be replaced, will have the receipt later in the day.

On or about 8/21/23, we were driving from Vermont back to our home in New Jersey when the sound system started malfunctioning. First, we lost all sound (safety warnings, as well as radio). The sound returned and then cut out again repeatedly. Then, the speakers emitted loud (full volume) static and popping sounds despite the audio system being "off." At the time, we were driving at approximately 65 mph on a highway with our two young children. The noise was so loud that it was difficult to focus on driving. The static and popping sounds continued until we pulled over and shut the car off. These failures have continued and increased in frequency since that time. Our safety was put at risk in two ways: 1) all of the safety warnings were and are muted and ineffective and 2) a full-volume static/popping sound while driving at highway speeds could have caused an accident. Subsequently, we did the following: -Googled the issue and found a relevant Technical Service Bulletin published by Toyota in September 2020 that applies to our make/model and VIN. It is labeled T-SB-0086-20 and can be found here: [XXX] . This suggests the issue applies to multiple Toyotas. The Bulletin indicates the VIN number where the issued stopped -- suggesting Toyota took steps to fix it. There has been no recall related to this issue and we were never notified of this issue. The issue is apparently related to a defective amplifier. -Brought our vehicle to our local Toyota service center (Paul Miller Toyota of West Caldwell NJ). An employee there was able to reproduce and confirm the issue and recommended replacing the amplifier. -Called Toyota to report the problem and register a complaint given the safety issues, failure to notify us of the problem even though it was known to Toyota, and the cost of repair ($2640). There were no warnings, messages, or other symptoms of the problem prior to the failure on or about 8/21/23.

Toyota engine coolant bypass trouble code. Seems to be wide spread reports amongst customers with newer generation 5 Toyota vehicles. Dealer quotes the 20 minute repair will cost $700-900 USD & the part itself is on back order due to the increasing failure rate of the part. The faulty part seems to affect the cooling system of the car but due to the increasing amount of reports & failures of the same part, the dealer should be recalling & replacing the part for free rather than billing customers $700+ dollars. For reference, my vehicle is a model year 2020 & has 19,000 miles & the part has already failed.
