“Engine Maintenance Required” appeared on the screen and immediately took the vehicle to my local dealership. Dealer claims “Engine coolant bypass valve” Has malfunctioned and needs to be replaced. They are charging $697.54 for the repair. After a little research online including nhtsa.gov this seems to be an extremely common issue and needs to be recalled.

2020 rav4 coolant bypass valve problem. This is an issue that is been happening in the 2019 and 2020 models even with less than 55,000 miles on it. My vehicle milage is 52,000 and now I'm having this problem and the dealer is charging $700.00 to fix the issue. I thought that Toyota vehicles were reliable but this is ridiculous.

I just bought my 2020 RAV4 in November with the lifetime powertrain warranty. By April, I had a “Engine Maintenance Required” light that would not go away. I took it to the dealership and it was my coolant bypass valve. $800 later, it’s fixed. Not covered under any warranty. Very common issue that Toyota charges a lot to fix.

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.

Engine maintenance required. Found that coolant bypass valve has malfunctioned. Warranty will not cover due to being over 30k miles.

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Toyota RAV4 Hv verdict →
