My 2020 Toyota?Rav4 was just diagnosed with an engine coolant bypass valve failure. The leak from this valve could cause engine overheating. This seems to be a well known defective?engine component that Toyota appears unwilling to address.??

Coolant bypass valve is faulty, coolant leaks into sensor. Coolant regulation is important for maintaining proper engine temperature and failure with this system can lead to larger engine issues, possibly leading to catastrophic engine failure. Problem verified by independent mechanic and dealer. Issue was inspected by dealer. The message -??Engine Maintenance Required // Visit Your Dealer-?? displays on dash.

1. The coolant bypass valve failed. I had to pay about $950 to get it fixed because it is a safety issue and was not covered under any warranties. 2. Yes they were. The coolant bypass valve is responsible for maintaining optimal engine temperature. With this part broken it, the engine can overheat as the coolant will not circulate through the radiator. 3. Yes. The toyota dealership informed us they see an unreal amount of people with faulty coolant bypass valves. It is an issue with the part. 4. It was inspected by the Toyota dealership in Round Rock. 5. No there was nothing to indicate an issue. I only discovered the problem because I got a "engine maintenance required" warning on my dash.

A week prior to this incident, the 2020 RAV4 was taken to Toyota for its maintenance check where everything was checked, replaced and changed. However, the last two days an incessant message keeps popping up on the dash stating -??engine maintenance required-?? Visit your dealer-?? taking up the entirety of the middle screen inhibiting my ability from seeing my speed, mileage, distance to empty, time, lane assist and other car information that I normally rely on. I have pressed the -??arrow back-?? or -??back-?? button numerous times but three seconds later the message pops again inhibiting me from being able to use necessary car controls to stay safe. The engine on the 2020 RAV4 needs to be recalled as my car only has 55,000 miles on it. I have talked to numerous professionals within the motor industry in which they state these engines have lower stability and life expectancy than PREVIOUS engines used in older RAV4 models. Not only the engine, but the messaging system within the RAV4 needs to be fixed immediately as the communication of maintenance WHILE driving is a hazard. If I cannot look at texts to even just simply read it, why is there is message bright and in the middle of my dashboard popping every 3 seconds with a bright red triangle stating that I need -??engine maintenance required, visit a dealer-??. This is a safety issue and one in which almost nearly cost me my life.

Code P268115... Every time you start the vehicle a message will display a "Engine Maintenance Required" and it will never go away, I was driving off road and the message would get in the way of seeing how my AWD is performing.

Check engine warning came on, dealer immediately knew it was coolant bypass valve since this is a very common incident with Rav4s recently. My valve was defective and leaking coolant so I had to get it replaced.

The engine coolant bypass valve has shorted and needs to be replaced. The dealer has confirmed the issue. First noticed when a message on the dash that said to see the dealer for an engine issue

p/a engine coolant bypass valve and coolant, and connector with pigtail, pins are full of corrosion inside connector. Items need to be replaced

Coolant bypass valve on all newer 2019 and up Rav4 models are known to cause issues or break at early mileage usually before 50k miles. It-??s a known problem with Rav4 owners and is backed by many claims on social media websites and internet forums. The cost for diagnostic of -??engine maintenance required-?? message on cars dash can range up to $150 and up for diagnostic fees only at Toyota Dealerships. Other independent mechanics cannot diagnose the problem message. Repair and replacement of $800 for parts and labor is ridiculous.

There seems to be a lot of folks online wanting a resolution from Toyota regarding a Coolant Bypass Valve that fails around 30k-60k miles on their 2020 Toyota Rav4's and other models. My Rav 4 just recently had the Engine Maintenance Required pop up on mine & I'm between 30k-40k. Some people had their issue a couple years ago and still nothing has been done about it. Toyota is charging close to $1000 for total repairs with labor for most of these instances. The community wants & needs a recall.

My vehicle that's only 4 years old stopped moving forward or backwards when putting the car in gear. The car turns on perfectly fine never gave us a warning or driving issues until the day it stopped moving on a highway. I got the vehicle towed to Avondale Toyota in Arizona and they told me not a single professional technician was able to find anything wrong with the transmission. I think to myself "not one of these professionals can find an issue with a car that's 4 years old? That's odd to me. But they advised me they could fix the vehicle with a brand new transmission for $8,000 but that's my only option at this point. I live paycheck to paycheck and this isn't something that could have happened to me at a worst time expecting a child in the summer. Im hoping it could be just a solinod or something like a misfire. Please help. Sincerely a father in need.
