Engine bypass valve sensor is faulty. Many users have reported this past 40k miles on RAV4 2019-2021

- Debary, FL, USA

2020 RAV4 hybrid. Vehicle doesn't start; requires a jump, which is inconvenient or unsafe, depending on where it happens. Intermittent occurrence, ~ 3 times/year. Toyota checked 12V battery, pronounced OK, of course the car was driven to the shop for the check, so was operating at the time. I've checked the battery when the car wouldn't start and found it to be a little low (11.5V) but by no means fully discharged. Not associated with leaving components on (we are careful to turn everything off) or weather; the vehicle is garaged in the winter. I turned off the "Bluetooth" system which we never used and haven't had this issue over the past year. Suspect that the "Bluetooth" system was operating even when the vehicle was off?

Got an engine maintenance required alert, took to Toyota and they advised the coolant bypass valve needs to be replaced at just 38,000 miles. Googled this and found out many 2020 RAV4 with the same issue at just under 40,000 miles. Also a common issue is the voltage being low and we already had to get the battery replaced once and still get alerts of it being low after replacement. Have to pay today $765 for the coolant bypass to be replaced, will have the receipt later in the day.

2020 Toyota RAV4 XLE purchased July of 2020. Just hit 35K miles and an "engine maintenance required" message appeared. The error message would not go away while driving and blocked the entire display screen. There is an issue with the Engine Coolant Bypass Valve that costs $700-$1000 to repair. The part and repairs are not covered by the 60,000 power terrain warranty.

I have a 2020 RAV4 Toyota with 60,000 miles.. I have replaced the car battery 3 times now Toyota has no clue why. The 2nd battery only lasted 8 months and it was a name brand battery (Die Hard).. The engine problem started with a warning light that i could not turn off.. I took my car to Toyota and they told me right off (without checking) it was because of a Coolant Bypass Value, the Toyota service lady said it was her 5th Rav4 this week with the same problem. I checked on line and was surprised how many Rav4 customers were complaining about the same issue so i reported it to you.. Toyota is charging me $900 to replace.

On or about 8/21/23, we were driving from Vermont back to our home in New Jersey when the sound system started malfunctioning. First, we lost all sound (safety warnings, as well as radio). The sound returned and then cut out again repeatedly. Then, the speakers emitted loud (full volume) static and popping sounds despite the audio system being "off." At the time, we were driving at approximately 65 mph on a highway with our two young children. The noise was so loud that it was difficult to focus on driving. The static and popping sounds continued until we pulled over and shut the car off. These failures have continued and increased in frequency since that time. Our safety was put at risk in two ways: 1) all of the safety warnings were and are muted and ineffective and 2) a full-volume static/popping sound while driving at highway speeds could have caused an accident. Subsequently, we did the following: -Googled the issue and found a relevant Technical Service Bulletin published by Toyota in September 2020 that applies to our make/model and VIN. It is labeled T-SB-0086-20 and can be found here: [XXX]. This suggests the issue applies to multiple Toyotas. The Bulletin indicates the VIN number where the issued stopped -- suggesting Toyota took steps to fix it. There has been no recall related to this issue and we were never notified of this issue. The issue is apparently related to a defective amplifier. -Brought our vehicle to our local Toyota service center (Paul Miller Toyota of West Caldwell NJ). An employee there was able to reproduce and confirm the issue and recommended replacing the amplifier. -Called Toyota to report the problem and register a complaint given the safety issues, failure to notify us of the problem even though it was known to Toyota, and the cost of repair ($2640). There were no warnings, messages, or other symptoms of the problem prior to the failure on or about 8/21/23.

There is a recall for the roof rails leaking water which can damage the air bags and electrical components. They will not fix the roof with new gaskets unless you actually see the water coming in. My concern is that it is leaking and I'm just not seeing it because the 110 degree weather. I do not want to be in an accident with my wife and kids in the car and have the air bags not work. They should fix the gaskets before it leaks and leads to further potential damage or even life threatening results(air bags being wet and not deploying). They will not fix my roof until it actually starts leaking even tho there is a recall in place. This is ridiculous.

I was driving and out of nowhere this warning came on engine maintenance required, and this now a normal maintenance required that means an oil change. The problem with this warning is the coolant bypass valve, and I-??m not the only one with this issue, my car has only 32100 miles only, this a ridiculous for a new car. Plus it seem that this issue only comes on with tha A/C

2020 Toyota Rav4, just around 25K miles, took to dealership to get regular maintenance service, (oil change, tire rotation). After a couple days, "engine maintenance required" message pops up. Plugged in code reader and brings up code "P268115" for "Engine Coolant Bypass Valve Circuit Short to Battery or Open". This issue is popping up for many recent year Toyota models (Rav4, Camry, Corolla) and is not being repaired by Toyota for free. They are charging $600 - $1000 to repair faulty part that is not the owner's fault and issue needs to be recalled.

Car has 26K miles on it (3 year 2 months old). A light appears saying Emergency Engine Maintenance is required. After research as this error is not in manual, found out it was a failed coolant bypass valve and this was a common failure/faulty equipment but we are being asked to pay full price to repair. A simple internet search shows 100's of consumers with same issue in same model and low miles.

I bought my car brand new in August 2020. In September 2021, my car died, I couldn-??t get it on at all, even to turn off the automatic emergency brake. No lights were left on, no doors ajar. Toyota came and jumped it so I could drop it off at the dealership. They ran tests and found no issues. Fast forward to March 2023, my car died again in the driveway. No lights left on, no doors ajar. It seems unreasonable that a brand new car would die twice in less than 3 years. Replaced the battery after the second time it died. How long until it happens again" I-??ve read that there seems to be a battery issue with the 2020 Rav 4. Will there be a fix" I no longer feel confident in my car.

error code P1C80-49 because of Toyota terrible manufacturing defect

- Gasport, NY, USA

The original battery completely drains when the car is off and no electrical equipment is kept on. This has happened on at least four occasions and car is unable to be turned on or even jumped with another car. The dealer (Toyota Umansky - Charlottesville, VA) has been unable to fix the problem and it it reoccurs. Based on my reading of this issue in similar models of the 2020 Rav 4 Hybrid, the "parasitic battery" can cause other electric malfunctions that would affect safety. Also, the description of this defect is substantially similar to the problems I face with my vehicle. I would like to add my model/ vin to the known batch of defective models with this problem.

The battery in my hybrid Rav 4 repeatedly goes dead if I don't drive the vehicle for 2 days. I reported the issue to my dealership and they charged the battery but it didn't fix the problem. The next time I brought it in for the same issue they did a software update they said would fix it. However, I have had the same problem once more and they again claim it's just a software update to fix, even though there have been no technology changes to my vehicle since they last "fixed it". In consequence, my vehicle will not start reliably which has left my husband stranded after work on a cold January day, and left me stranded at home from getting to work two additional times. Every time I bring it to the dealership they dismiss the problem but none of their attempts have resolved the issue.

when car is subject to rain or car washed, the headliner gets saturated at the "A" pillar and the "C" pillar. This water seems to be coming from under the roof rails. I have tested sunroof drain and they are open leaving the only other area to leak at the insertion of the roof rails. I have never had anything attached to them to add excess weight but have also hearing and finding many other reports of this happening. My concern is having the headliner ruined AND malfunction of the airbags. This has been reported to my Toyota dealer twice and I have been told that they are unaware of any issues with the seals on the roof rails.

On September 16, 2022, I discovered the vehicle battery died. I charged the battery through a jump start. The car worked normally, except the radio and infotainment system failed to work, constantly rebooting in an endless cycle while the car was powered on. On September 29, 2022, I brought the car for service at Star Toyota of Bayside, New York, to diagnose the issue. On September 30, 2022, the service advisor told me that the entire infotainment system had to be replaced at a cost of about $1,400. The car is out of warranty apparently due to its mileage even though it is from 2020. The fact that a simple, common issue such as a dead batter caused this catastrophic damage to the infotainment system is totally, absolutely unacceptable. I now question the electrical integrity of these cars and I hope that NHTSA will undertake an investigation. I also seek full reimbursement from Toyota for all costs associated with this repair. I have video of the system rebooting. The file is too large to upload to this website with its 10MB file size limit. I'd be happy to provide it by other means. Thank you for your consideration.
