After only 35k miles the car start showing a failure in the coolant by pass valve that could cause major failure of the engine. It has been reported that it is an ongoing situation with most 2020 rav4. The repair is not covered by warranty and it cost over $700.
2020 RAV 4 little under 34,000 miles. Coolant bypass valve needs to be replaced. “Engine maintenance required visit your dealer” takes place on dash and cannot be cleared.
Air coolant bypass valve malfunction. Engine maintenance error message pops up, does not cool properly. Leaking ac fluid. Confirmed by dealership. Costs around 800 to 900 dollars to repair. Parts must be ordered ahead of time. No warning, just message showed up and will not go away. Doesn't let me see the speed I am going on the display since error message keeps popping up every minute.
I took my car to the dealer this week and was told I need to replace both front lower control arms. I noticed other cars for that year have a recall for this specific problem so I called Toyota but I was told that I had 0 recalls on my vehicle.

The problem starts with a service notice for the engine. when they check it at the dealer they say it is the coolant bypass valve and they charge 1000 dollars to fix the problem. a new car is not supposed to have these types of problems. they are making a lot of money by changing this part because there are many cars of the same year and with few miles that come to the Toyota dealer for the same problem.
I have had a Service Engine message on my dash that would return within seconds of my hitting the button to signal I received the message. When I took the vehicle to the dealership I was told it was a leaking coolant bypass valve and would need to be replaced. I was told the cost would be $215 plus three hours of labor. The final cost was $240 for the parts and $709 for the labor. The vehicle only has 31,209 miles on it. As I have researched the part, I have found numerous people have had the same issue within a similar range of mileage.
I searched online after the Toyota dealership told me that my coolant flow control valve is failing. I became aware that it is a common issue for my 2020 Toyota Rav4. The warranty does not cover it even though it should be part of the powertrain warranty.
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.
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.
Engine coolant bypass valve

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.
Recall for passenger air bag may not deploy. Remedy is not yet avaliable, I purchased a safe vehicle for my family and now I shouldn’t have passengers in the front. Vehicle was in an accident 7/29/2024 and air bags did not deploy. I feel very unsafe driving this vehicle. Vehicle is still waiting for parts to be repaired from accident.
My engine maintenance screen kept coming up. Bought it to the dealership & was told that my coolant bypass value needed to be replaced. Not covered by warranty & $700 to replace. This is a known issue with Toyota rav4.
While I was driving the power steering light came on and lost power. A message came on the vehicle history alert. After driving slowly for 2 miles it when away and got power back on the steering
What component or system failed or malfunctioned, and is it available for inspection upon request? The flow shut-off valve (coolant leak) failed. This exact component was later included in Toyota’s official recall. The defective part was diagnosed by a mobile mechanic and replaced at a licensed independent auto repair shop. The failed component itself is no longer available, but all receipts and repair documentation are available upon request. How was your safety or the safety of others put at risk? The failure of the flow shut-off valve caused a coolant leak that created a significant safety hazard, as it affected the vehicle’s performance and drivability. This posed a risk to both my safety and the safety of others on the road, which is why I had the repair completed immediately before the recall was issued. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue was first diagnosed by a mobile mechanic and then confirmed by a reputable independent auto repair shop, who identified the flow shut-off valve coolant leak as the root cause. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No inspection was conducted by Toyota, police, or insurance representatives. However, Toyota later issued a recall for this same component, confirming it as a known safety defect. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The vehicle experienced noticeable performance issues prior to the failure, which prompted me to call a mechanic. I did have multiple warning message and coolant leaking in addition to the performance issues of the vehicle. These symptoms appeared several months before Toyota’s recall notice for the flow shut-off valve coolant leak arrived.
Engine coolant valve Malfunction
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.
I had a message on my dash for "engine maintenance required" but my check engine light was not on. Coolant bypass Valve failed, it is definitely a known issue and the dealership knew the likely issue before the car was seen by any technician.
Premature Coolant bypass hose failure at 120k Very common according to online forums $1000 cost of repair
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.
PARASITIC BATTERY DRAIN DEFECT complaint: prior to 07/16/2024, I received a "low voltage" error on my Toyota RAV4 screen a few times. On 07/16/2024, I took it to the dealership. My battery tested "good" and the Toyota dealership charged me 39.95 to tell me that everything was working well on my vehicle. The very next day (24 hours later), 07/17/2024, my vehicle would not start and had to be towed to the dealership. The tow truck driver told me the battery was "dead" (based on his measurement) and leaking acid (based on a smell). Toyota charged me 272.52 to replace the battery on 07/18, that was supposedly "good" two days prior. This is a known issue to Toyota, part of a class action lawsuit referred to as "Parasitic Battery Drain Defect." This is dangerous since I was stranded with a car that would not start in a summer day of high heat, but could have been much worse in other circumstances. The tow truck driver told me that the battery acid could be dangerous. Toyota should be providing a fix and a recall, but they had no solution for me other than a new battery which is a "quick fix" (but not a real solution) as described in the Class Action lawsuit documents.
I received a notice in the mail from Toyota with Toyota Recall # 23TA15 or NHTSA Recall # 23V-865. The notice clearly states that they will notify consumers when the remedy is available. However, it also states that if your vehicle's supplemental restraint (SRS) warning light is illuminated, then your vehicle may be experiencing symptoms related to this safety call. Earlier this morning, 7/16/24, my car did show the SRS warning and told me to contact my dealership. I have tried discussing this issue with my local Toyota dealership located in North Austin TX. They have stated that the car is in fact not safe to keep driving, and the parts to fix the vehicle may take as long as 3 months to 6 months to come in. They are refusing to put me in a rental car until the vehicle can be fixed unless I agree to pay out of pocket up to $12 per day over the course of 3-6 months. I am already paying $450.00 a month for a vehicle that is unsafe to drive, but am being forced to pay additional out of pocket expenses that I am unable to afford in order to keep myself and my family safe. This is unreasonable considering that the recall is not the consumers fault. I hope photos of the SRS warning displaying on my car and proof of the Toyota dealership informing me that the vehicle is not safe to continue driving until the car is fixed.
Bypass coolant valve needed to be replaced after engine maintenance required warning came on
my 2020 RAV4 (48,000 miles), when I start the engine and turn on the A/C, the warning light comes on:Engine maintenance required.
Engine maintenance required message. Need to replace coolang bypass valve known to be common issue with rav4 2019 up models
Coolant bypass valve replacement has been happening to many new Toyotas and needs to be recalled
Coolant bypass failed at 55,000 miles. This car has barely been used. This car is almost in mint condition and the coolant bypass has failed resulting the car not being able to be driven at all until fixed. The dealer is charging over $600 to repair. This is an ongoing issue with hundreds of Toyota RAV4 owners.
Recurring engine maintenance required alert due to a Heater coolant bypass valve fail issue at 58,100.

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.

Coolant bypass valve needs to be replaced. Car under 60k miles and should be covered on the powertrain warranty but is being required to be repaired out of pocket otherwise will ruin engine
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.
my car has barely 40,000 miles on it when I received an "engine maintenance required" sign. When I went to the dealership, they said its the coolant bypass. I went on reddit and many 2020 rav4 Toyotas are having the same issue. This should be recalled as the repair is too expensive - above $800.
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!
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.
The contact owns a 2020 Toyota Rav4. The contact stated while driving 60-65 MPH, the vehicle started shuddering and the engine was overheating. The message "See Dealer for Maintenance" was displayed. The vehicle was taken to the dealer, where it was diagnosed, and the dealer determined that an unknown cooling system valve needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 35,000.
I replaced my battery a little over a year ago and have come back to my battery completely dead and unable to turn the engine over. The first time it happened my vehicle had sat for 4 days. It has done it sporadically and sometimes within 2 days of incidents. I have checked to make sure no components were left on to cause this issue. It has left me stranded multiple times.
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.
Engine coolant valve failed. Known Toyota issue for this model and no recall has been issued.
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 have researched this warning and found it to be very common. And the price to fix it upwards of $900 ??!! I was even quoted this when I called my dealer. I have found threads going back 1 to 2 years stating this repair. No warranty, no recall. as I said I have UNDER 30k miles too.
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.
Vehicle popped up Engine Maintenance Required. Not an oil change reminder as I’d just had that done a week ago. RAV4 XLE is at 60,820 and this is a common issue from the looks of it. Dealer wants $800 to fix but no physical codes came up
Coolant Bypass Hose had to be replaced on a vehicle that only had 80,000 miles and only 4 years old. “Engine maintenance required” displayed. Took to dealer and code popped up with an issue with the coolant bypass hose. Nothing occurred to trigger replacement…it was a faulty part to begin with.
on 5/28/24 the vehicle air bag lights and front passenger seat light was flashing and an alarm continuously went off with a message to visit a dealer for service. On 5/29/24 the vehicle was brought in for inspection to a Toyota dealer. I was told an electrical wiring needed to be replaced. Dealership did that but it did not correct the issue. Codes were not resetting. They are now saying it is a wiring/electrical issue under passenger seat and saying they have been communicating with Toyota. We do not have a Toyota extended warranty but vehicle has 32K miles and are told by dealership Toyota should be covering. I am submitting this to have this on record as we have warning lights, messages, etc. occurring which is a safety issue under NHTSA. Dealership keeps increasing charges for parts and labor and states our 3rd party warranty may or may not cover charges. They are trying to determine the issue and if Toyota will cover and resolve.
The contact owns a 2020 Toyota Rav4. The contact stated that on several occasions while driving at various speeds, the "Engine Maintenance Required" message was displayed. The vehicle was taken to a dealer where it was diagnosed and determined that the coolant bypass control value needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 60,000.
