2020 TOYOTA RAV4 Engine Problems

The contact owns a 2020 Toyota Rav4. The contact stated while operating the vehicle, the message "Engine Maintenance Required - See Dealer" was display on the instrument panel. No warning light was illuminated. The local dealer was contacted, but the vehicle was not diagnosed or repaired due to the cost. In addition, the contact received notification of NHTSA Campaign Number: 23V865000 (Air Bags) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 47,000. VIN tool confirms parts not available.

A warning message saying "Warning Notification A warning light was turned on. Would you like to call an operator?". Diagnostic performed by Yark Toyota confirmed coolant bypass valve malfunction which can cause overheating. Warning comes on when I turn on the A/C. I now have no air conditioning in the hottest summer I can remember. Repair costs just under $1,000 total.

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...

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 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.

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.

I got the "Engine maintenance required. Visit your dealer" warning. (conveniently after my scheduled oil change 1 week later) My vehicle is a 2020 Rav4. I purchased it 2022. It has UNDER 30k miles.

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.

Coolant bypass valve error

Coolant bypass valve

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.

Coolant bypass sensor is faulty

Bypass coolant valve failure

Engine maintenance required see dealer

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...

I kept getting an engine maintenance message. The coolant bypass assembly failed.

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.

I having the engine maintenance like tons of other people and it seems is a 800$ fix..... to many people having the same issue and it seems is the return valve hose for everyone

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...

The coolant bypass valve failed on my RAV4 at 67,757 miles. There are multiple similar complaints online and I would like to bring it to the attention to the NHTSA. The engine service light cut on and the dealership replaced the valve to make it go away.

2020 Rav4 engine bypass coolant valve is faulty. It could lead to overheating and possible engine damage. This is a known issue and just google to see how many people have been screwed over by this faulty equipment.
