Premature coolant bypass valve failure. Vehicle has less than 70k miles, but past warranty, "Engine Maintenance Required-See Dealer" light randomly came on one day and would not go off. Scanner pulled no codes as to what the issue would be. Found out it is a known issue as hundreds, if not thousands of Toyota drivers, have experienced this and that specific warning message indicates that it is due to the coolant bypass valve having failed. Clearly this is a known issue.

Maintenance light is keep showing even after the oil change. After the inspection, mechanic found that it is due to Coolant Bypass pipe/hose. I didn't see a recall but I had to get it done before it get worse. It cost around $500 to change the Coolant Bypass pipe/hose with labor. Hence, I reporting to escalate it and requesting for reimbursement. Thanks.

I noticed an “engine maintenance required” message on my dash when driving home yesterday. I took the car to the dealership today to have it inspected. I was told I need to “replace the engine coolant bypass valve malfunction” for $738.31. Even though I only have 38,984 miles on the car I was told it was outside of the basic warranty and was not covered by powertrain warranty. When I looked online on several Toyota Forums I noticed other 2019/2020 Toyota RAV4 owners were reporting the same exact issue. I believe this warrants an inspection to see if a nationwide recall is needed and Toyota should cover the cost and refund any and all out of pocket expenses. I’ve driven Toyotas my entire adult life and have never had any issues like this before. It’s very disappointing.

Engine Coolant Bypass Valve Failed expecting close to $1000 for repair. This is not a normal failing part. 2019-2023 rav4 and corollas have this faulty valve that fails prematurely. It is well documented throughout the internet and forums of people having the same issue. 3 dealerships I have spoken with list this as a well known issue that is common with the car. It throws engine maintenance required sign non stop.

“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.

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.

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.

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.

Engine Maintenance Required indicator turned on at around 42K miles. My oil change was not due until 45K miles. I had my oil changed at around 43K miles and the indicator still remained on. Issue was the coolant bypass valve need to be replaced. Many other Rav4 owners have had the same issue. The faulty coolant bypass valve if failed while driving could of caused my car to overheat and possibly catch on fire depending on how sever the overheating is while I'm driving.

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.
