2020 Toyota Rav4 Engine Problems

Your water pump suddenly failed completely while driving on the interstate, causing a sudden jolt and rapid deceleration that put you and your passengers at risk. The mechanic indicated this failure may have been hastened by issues with the engine coolant bypass valve that was recently serviced under recall. The mechanic noted this is a known issue with Toyota vehicles, suggesting that plastic water pump components may not hold up well to the corrosive coolant at high temperatures. The repair will likely involve replacing the water pump and potentially addressing the bypass valve system.

Your check engine light came on. When you stopped to refuel, your car stalled and wouldn't restart. A mechanic diagnosed the problem as a faulty fuel pump. This is a critical issue since your car won't start and needs immediate repair to get it running again.

Your RAV4's flow shut-off valve failed, causing a coolant leak that affected engine performance and created a safety hazard. You may have noticed warning messages, coolant leaking under the vehicle, and drivability problems before the failure. The repair involves replacing the defective flow shut-off valve, which Toyota later recalled for this exact issue.

Engine coolant bypass valve

Engine maintenance message appeared on my dash. I took it to Big O's Tires and Service a car repair service provider. Upon connecting to the car and inspecting they told me it was a faulty possibly leaking engine coolant valve. The cost to repair is $916. This may cause the engine to overheat and possibly fail due to overheating. This can be very dangerous because it will happen if it does happen while driving which could cause an accident. I have not fixed the issue yet due to a lack of funds but will have to fix it as soon as a get paid because I drive my family in this car and cannot risk catastrophic engine failure. Please have Toyota recall this part as it is a very common failure amongst 2019-2023 Rav4s. A class action lawsuit is underway due to how often this issue arises. Thank you for your time.

Coolant Bypass Valve failure at 40k miles - 2020 rav4. Replacement at dealership is costing over 800$.

The coolant bypass valuve has failed. There looks to be a class action lawsuit currently underway.

I have a 20202 Rav4 Hybrid and the engine short block has malfunctioned due to no error on my part, in my research there was a recall for this EXACTLY this issues in other cars of this year/make/model - although my vehicle initially did not qualify for this I believe that this in fact related and that Toyota should be responsible for the repair or replacement of the engine. The car is currently with a Toyota Dealership Service Center, Lake City Toyota in Seattle, WA but they have not been helpful. They have given me vague answers and have sent the engine offsite to a machine shop and keep requesting that I pour additional money into fixing an engine that clearly had a manufacturer defect. My car has always been serviced at Toyota dealerships, as suggested by Toyota. My car has never had previous issues until the engine light came on one day, i checked the coolant and it was empty - first replaced the fluid, let it sit overnight, then drove it around the block to circulate the coolant - when the reservoir emptied again I immediately made an appointment to take it in. The Dealership has not given me any paper invoices or written confirmation/notice of what is happening aside form continuing to ask me to pay more money to fix an engine that is clearly related to the national recall issued.

See attached document for complaint.

Coolant relief valve failure

My Rav4 xle 2020. Starting the engine up it shakes and blows white smokes for 5 seconds and smooths out. This symptoms happens every time when engine is turn on I have to fill coolant once a week.

Shortly after having vehicle serviced at Toyota the engine maintenance light came on. Imagine my surprise at learning that many other Rav4 owners have the same exact issue right around the 65,000 mile mark. But regardless I toke it to the Toyota dealer to have them diagnose the issue and under the advisement of the technician opt in for the repair so that my car “wouldn’t have more serious problems as a result [of not fixing the coolant bypass valve].” So now I have to pay $1000 for repair when I have had the car just the tiniest bit over 4 years (which is how long the warranty lasted).

Engine Maintenance Light on. After inspection at dealership, the cause was determined as Coolant By-pass valve stuck closed

I have had an "Engine Maintenance Required" warning light on since I purchased the vehicle (used) and have had it checked out by my local mechanic and the Toyota dealer. It is due to the coolant bypass valve malfunctioning. Apparently this is an extremely common issue according to the class action lawsuit and should NOT be put on the customer to pay for this when my odometer has not even hit 60k. A recall needs to be issued for this once and for all.

Coolant Bypass Issue. Engine Maintenance and contact dealer on the dash board.

While driving with the air conditioner on a message appears on the instrument panel ENGINE MAINTENANCE REQUIRED. From researching this message on the internet it appears this is due to an engine coolant bypass valve problem. From this internet search it appears to be happening to many other peoples Rav4. The cost of having this valve replaced appears to be close to $1000. It appears that this problem is a common thing. Toyota needs to have a recall on this problem. Most people report this happening at various mileage.

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.

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.

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 or something like a misfire. Please help. Sincerely a father in need.

engine coolant bypass valve short to battery

At 68,000 miles my Toyota Rav4 needs to have coolant bypass valve replaced. My understanding is this is getting to be a common problem and would like to see it placed on a RECALL. Thank You.

My 2020 Toyota RAV4, "Engine Maintenance Required: See Dealer" message came on my dashboard and would not go away when I cleared it. I took it into the dealership, and they stated that they had 1000s of RAV4's come in with this same message. They said it was the engine's coolant bypass valve. After diagnosing the problem, the dealership confirmed it was the coolant bypass valve. This was very expensive to fix, $926.67, to be exact. For a car that is just over 3 years old, less than 40,000 miles, Toyota knew of these defective parts and still put them in to get the car out of their factory and onto a dealer’s lot. They do not care if it kills anybody, just get the car sold. Toyota needs to have this bypass valve as a ‘recall’ and issue refunds to THEIR loyal customers, so they call us, loyal customers, not sure how much longer I will be a 'loyal' Toyota customer. I addressed this matter with Toyota Motor Sales U.S.A. Inc. and the dealership I purchased my 2020 RAV4, Milton Martin Toyota of Gainesville, GA. They just blew it off. So, I went to another Toyota dealership to have the repair done.

Engine coolant bypass valve needs to be replaced. Seems to be a very common issue in 2019-2023 RAV4s but Toyota has not issued a recall and is making customers pay $600-900 to fix. I ask that Toyota take responsibility and issue the recall now so this can be fixed!

Unknown engine maintenance light alert check light Recommend engine coolant bypass valve with gallon of coolant

Part # 16260-f0010 - engine coolant bypass valve failed due to open or internal short and caused a Engine maintenance required warning which blocked other safety items on the display. This is a wide spread and known issue for Toyota which can result in engine overheating due to leaking coolant and result in engine failure (severely damage the engine) leading to engine stall and/or fire risk, causing potentially unsafe situations to occur for the driver and others in the vehicle. The error code is "P268115" for "Engine Coolant Bypass Valve Circuit Short to Battery or Open". Yes. the problem has been reported with NHTSA by others and from some dealers. When I took the vehicle into the dealership, and they stated that they had many RAV4's come in with this same message. They immediately said it is some engine component failure. There is a related NHTSA Campaign Number: 20V064000 (Engine and Engine Cooling) and also a recall related to it (but not for my vehicle's VIN): [XXX] Yes, the component has been inspected by the dealer. No, there was no warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear Engine maintenance required warning sign did not go off which is good to have warning but blocking other safety items on the display dash board is a safety hazard. This could only be removed if we spend $185 for diagnostics (which is charged knowingly that this has been a reported/unreported problem around the 2.5-4yr/30-60k miles for the vehicles with this part) and fixing the part at the dealer and resetting the code. The cost of the part is affordable but the labor charge of $700 is exorbitant. The part replacement isn't covered under manufacturer's warranty. This part warrants recall as this is accidental poor manufacturing issue that is outside the scope of normal wear and tear and especially when the owner is not at fault. I'm expecting more repairs in future. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I believe, it is coolant bypass valve which needs to be replaced. I read my forums in [XXX] and [XXX] and many others have complaint about the same. Toyota has to have a recall on this poorly manufactured bypass value. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In my 2020 Toyota RAV4, a "Engine Maintenance Required: See Dealer" message came onto my dashboard and would not go away when I cleared it. I took it into the dealership, and they stated that they had many RAV4's come in with this same message. They said it was most likely the engine's coolant bypass valve. After diagnosing the problem, the dealership confirmed it was the coolant bypass valve. This was very expensive to fix, and for a car that is just over 3 years old it seems unusual for this to occur so soon and to so many other card within the same year and time period. This part needs to be recalled and reimbursement should be provided to those who had to pay hundreds of dollars to get this fixed when it is very likely a faulty part.

This is a common issue for the 5th Generation Rav4. It doesnt read fault codes on the OBD2 scanner, but the ENGINE MAINTENANCE alert continuously comes up because of a faulty coolant bypass hose/valve. Toyota OEM Part # 16260-f0010. This should be a recall. Instead, we are paying out of pocket to get this fixed.

Coolant Bypass Valve on my 2020 RAV4. There needs to be a recall; even Toyota dealerships in the Dallas/Fort Worth metroplex say that there needs to be a recall. Service advisors say this is a big problem they see daily and with all cars and at all mileage. The cost to replace the Coolant Bypass Valve in my car = $855- RIDICULOUS!! In addition, due to the constant “Engine Maintenance Required” message on the screen triggered by the Coolant Bypass Valve needing to be replaced, that can’t be removed, all other car related information and/or service issues, is unable to be seen…which is dangerous!! Toyota used to be one of the best car manufacturers for quality and reliability, but now, their quality has tanked…

I was advised that the vehicle was to not be driven long distances as it could result in more damage to the car. This is my 4th expensive repair on this 3 year old car in 1 year. This is my very first Toyota, & I am extremely disappointed. I bought a Toyota anticipating a low maintenance, high quality vehicle and have had nothing but issues.

The coolant bypass valve is defective on a 3 year old single owner, well maintained under 50,000 miles vehicle.

Coolant Bypass Value Replacement required on my 2020 Rav 4. I have 33,000 miles & purchased in 2019, so it is not covered under warranty. The dealer is charging me over $850 to replace. I have been told by the Dealer that this is a "KNOWN" problem with this and other Toyota models. Why is there not a recall or extended warranty on this repair if so many owners are paying hundreds of dollars on relatively newer cars with the same FAULTY PRODUCT? I would like Toyota to reimburse me. I am having the car repaired tomorrow because I have been told it is dangerous to use the vehicle in this condition. Please assist me with ways to get reimbursed from Toyota and for others to receive repairs at no cost, especially on vehicles under 5 or 6 yrs old. thank you.

At approximately 60K on my 2020 Toyota Rav4 XLE The Engine Maintenance Required Visit Your Dealer message came on my dash. It's been a known issue for many Rav4's not to mention other Toyota models for the engine coolant bypass switch to have gone bad. The vehicle is available for inspection upon request. My safety and whom I may be transporting can be put at risk if the engine refuses to start or operate as normal and can leave us stranded. The problem is known by Toyota and many of these valves have been replaced at the dealer for a very high cost.

Coolant Bypass Valve breaks easily and in many RAV4s and Corollas. When this happens an "Engine Maintenance Required" see your dealer message comes up in the heads up display and won't go away. Makes seeing the important details of speed, miles to empty, etc on the screen impossible read. It is a known issue by Toyota and they refuse to do a recall.

The coolant bypass valve failed. If this was not repaired it could have resulted in leaking coolant which would eventually cause engine failure. The issue started with a message on the dash stating there was "engine maintenance required" on 6/28/2023. I took my vehicle to my service provider the next day, 06/29/2023. The dealer service tech knew exactly what the issue was before diagnostics because they had 4 RAV4's come in that week with this same issue. The bypass valve was replaced on this visit and I paid for the job. I have since seen many posts online with this same failure on 2019 and 2020 RAV4 models. It appears Toyota had a recall for this in 2020 for Hybrid RAV4's and some non hybrid RAV4's but apparently my vehicle and many others were not included in this recall. https://www.greencarreports.com/news/1127163_some-2019-2020-toyota-and-lexus-hybrids-recalled-for-coolant-leak-concern This recall needs to be extended for the other vehicles like mine that are currently being affected by this faulty part.

Over a month ago, I had an engine maintenance required error light come up on my dashboard. I had done some research and found that this has been an ongoing issue with multiple RAV4s. I discussed this recently with the dealership as well as contacting Toyota’s customer service and they did not address the issue as a concern and replied I would have to have the dealership run a diagnostic to see what the issue was. I already knew the answer from multiple threads I had read prior to my appointment. I ended up paying $190+ for the diagnostic of what I already knew was going to be the issue. And now I have an appointment to have the part changed next week for another $600+

The vehicle fails to start if it has been sitting for only 2-3 days, once it failed to start just after an extra long day at work. I have it serviced faithfully every 5,ooo miles and have brought it in an additional 4 times for this problem. I filed a report with Toyota Corporate on January 5, 2023 and they had someone call the next day while I was at work. I called back 6 times but have never been able to actually speak to a case manager. I keep getting promised a call back multiple times but never received one. I even called tonight when I was promised a call, the case manager was available, but told the agent on the phone with me that he would call me by the end of the day. He never did. I called back again and was promised a call tomorrow. I keep getting the same run around. I have literally spent hours on the phone with them, many many hours at the service shop, and many hours inconvenienced by having my car battery jumped.

I was driving down the hwy doing 75mph, herd a loud bang and vehical lost all power, was passing an exit right at the moment this happened and immediately pulled out and was able to coast to a stop. The exhaust smoked for a while and it left a huge puddle of what looked like motor oil where it stoped and never started back up again. Ended up having to have it towed to a dealership where im told it threw a rod and being as how there is already a recall on this engine for possible cracks im thinking this model probably need to be added to the recall list. The car has been sitting at the dealership where the tow truck left it. There is a recall involving the possibility that cracks could form in the engine, leading to coolant or oil leaks and stalling, overheating, or engine fires. If I hadnt had both my hands on the wheel I could have lost control and killed myself or worst off if there had been cars around me I could have caused a fatal accident. In this case the problem cant be reproduced as the engine is ruined but would be happy to offer to have it inspected. I have kept up with all the manufacturers maintenance request and there were no signs of a problem prior.
