What 627 owners told NHTSA about the 2020 Toyota RAV4 Hv

I bought the 2020 Rav4 XLE back in 2019 and had driven for four and half years now. I went to the dealership to get my routine oil change just this Monday July 29th 2024. As usual, the dealership did multi-inspection on my Rav4 and didn't find any problem that requires immediate attention. Two days later, a warning message popped up on the MID screen right after I started the car and read "Engine Maintenance Required". After searching online, calling both local mechanic and Toyota dealership, it happens to be a well-known issue for many 2019-2023 Toyota models including Rav4, Camry, Corolla that the faulty coolant bypass valve has to be replaced. I'm not a car person and I don't know much about cars but I have had the radiator broken while I was driving on my old car due to coolant related issue and almost got me into an accident so I know I shouldn't overlook any issues related to coolant. That being said, Toyota dealership knew about the issue, my local mechanic heard about the issue, an overwhelming number of users had reported the issue on online forums, and with no surprise, a class action lawsuit was filed regarding this issue on June 2024. For a solid car brand that advertises reliability and accountability for its vehicles, not informing or recalling for affected customers is extremely disappointing and unacceptable. After all, I had to pay $785 out of pocket for a repair that should never be done in less 5 years/45000 miles.

52,000 miles, and was just informed the coolant bypass valve has failed. This is apparently an issue with ALL 2019~2022 Toyota Rav4 vehicles. It was a known issue to Toyota, using substandard parts. It results in an error message that cant be turned off, masking all other messages, and can only be fixed by a dealer for over $1,000 in costs.

A code for the coolant bypass valve appeared through an independent service center. Warning message shows "Engine Maintenance Required", when air conditioning is turned on and does not go away. Warning message does not show when air conditioning is turned off. I had a independent service center check any damages to the coolant bypass valve, show that the part was faulty. Through various testimonials Toyota Rav4 owners, they also had the same issue. Warning message started at approximately 55,000 miles and has not gone away even after service. Quote for repair goes above $700, although part has been claimed to be faulty and not disclosed.

Recurring engine maintenance required alert due to a Heater coolant bypass valve fail issue at 58,100.

I got a message popup saying "Engine Maintenance Required" which is different from the oil change reminder. I cleared it thinking it was about an oil change (that isn't due yet), and it came right back. I took it to a mechanic who ran diagnostics and wasn't able to find the issue. After a few internet searches, I found that the coolant bypass valve is a known issue on certain years of this vehicle. I followed the suggested steps for resetting it (to turn on the vehicle with the heater on, then lower the AC temp without hitting the lowest temperature setting). It's currently working as a fix, but I'm concerned about any long-term situations that could arise.

We replaced the original battery on May 27, 2024. A few weeks later, on June 15, 2024, an "Engine Maintenance Required" message appeared on the display screen. A local mechanic diagnosed the code and stated that the oil level was low so we added one quarter of motor oil. We also called the dealership, which stated that this code generally indicates a coolant bypass valve malfunction. We topped off the coolant fluid but the "Engine Maintenance Required" message still appeared (we were not able to clear it). A few days later, we took the vehicle to another mechanic, who informed us that the coolant bypass valve was broken and needed to be replaced. Given the 95-degree temperatures, we felt that we had no choice but to replace the broken valve because we did not want the engine to overheat. So we paid $570.28 for the mechanic to replace the coolant bypass hose and valve. The mechanic stated that this issue should not occur in any vehicle with only 38,000 miles, which means the valve was likely defective to begin with. It is suspicious that this issue occurred about two weeks after we replaced the battery and about 2,000 miles after we surpassed the factory warranty. Please investigate!

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.

Engine maintenance required warning on dash that prevents me from seeing any dashboard information. It is not possible to turn off the warning. Dealership say it is due to faulty coolant bypass valve. There is a class action lawsuit regarding this part failing.

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.

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.
