Valve matic is messed up. According to my research this is a known issue with 2020 Toyota corollas.
Engine, Jan 26, 2025
Vehicle maintenance light won’t turn off, stays off if car started with AC off but comes on and stays on while AC is running. Coolant overflow valve malfunction
Engine, Jan 12, 2025
"Engine maintenance required. Visit dealer" message appeared about 2 years ago. The message appears when I turn on the A/C or heater and will not go away, which affects multiple functions such as speedometer and text function.
Engine, Jan 10, 2025
Engine coolant leak from an issue with a valve that allows coolant to drip on other parts of the vehicle. “Engine Maintenance Required” is displayed on the instrument cluster and causes the A/C to not function normally.
Engine, Jan 6, 2025
I keep getting a warning sign on my dashboard stating that "Engine maintenance required. Call your dealership". After scanning for codes, I get the code P2681, or that the Engine coolant bypass valve is faulty. After looking online it appears that this is a common issue with this car model. There is a class action lawsuit for this right now since the part is known to be faulty and can crack and leak engine coolant. Toyota has refused to issue a recall for this and will charge you to replace this faulty hardware. I also am not able to clear the message while driving and it will constantly pop back up distracting me while driving and making me unable to see any important warning on my dashboard. This is endangering my ability to safely drive my vehicle.
Electrical system, Dec 23, 2024
The vehicle flashes ‘connected device is not compatible’ with the ‘SOS button flashing continuously red then green.’ This message causes the microphone to remove 1 to 3 seconds of sound every 5 to 15 seconds making a clicking noise when speaking on vehicles Bluetooth. This is typically corrected by a DCM reset and firmware update. Not only is this incredibly inconvenient during normal conversation but having to repeat random portions of the conversation is irritating at best. Recently I had to make a 911 call and had to repeat myself several times to request emergency services. This glitch caused the emergency 30 second call to be extended roughly 1 1/2 to 3 minutes delaying response time. If the clicking occurs while the other person is speaking this is not noticeable. This is an identified issue only covered under basic warranty with specific TSB correction. This defect causes portions of vehicle occupants conversation to be removed and replaced with a clicking noise.

There was a maintenance required notice on my dashboard and I searched up that it was my coolant bypass valve having an issue. Apparently it’s a defective part in Toyota Corolla and rav4 models from 2019-2023 I believe. The notice would come on and off each time I would start the vehicle. The dealership has confirmed this issue is common and after having it inspected and diagnosed, it was indeed the coolant bypass valve. My safety and the safety of others were fine, my engine would’ve been the unfortunate casualty if I did not take care of this.
Electrical system, Nov 26, 2024
I am experiencing a recurring issue with the Data Communication Module (DCM) in my 2020 Toyota Corolla. This component was previously subject to a recall, which I addressed at a dealership. However, the problem persists, and many other Toyota owners, including those with RAV4 models, are reporting similar issues. Discussions on forums such as Toyota Nation and Toyota Owners Club highlight these ongoing concerns. My vehicle is out of warranty, and replacing the DCM is estimated to cost over $800. I have confirmed that the issue lies with the DCM system, as removing the corresponding fuse eliminates the error message on the multimedia system. However, this circuit also powers the right speaker and microphone, making it impractical to simply disconnect the module. The local dealership has quoted $205 for diagnostics, despite my prior identification of the problem. Revisiting the original dealership where the recall work was performed is not feasible, as it is located across the country. Toyota has not offered a remedy, leaving me without an affordable or practical solution to address what appears to be a manufacturer fault. I am seeking assistance and accountability for this persistent and widespread issue.

Car would not start/turn over - Not battery related. Toyota determined the ECU went bad and stated the cause was improperly jumping the battery. The issue happened randomly one day (car was driving fine previous days)

"Engine maintenance required" - Coolant bypass valve is the cause
Other or unspecified, Nov 19, 2024
Engine maintenance required notification came on. Car is only 3 years old. Dealership stated that the coolant bypass valve needs to be replaced and it could potentially cause a fire. Service professional at the dealership stated that this is a common issue and most of the time Toyota warranty doesn’t want to repair it, also said that it should be recalled. I have also seen hundreds of people complain about this on Rav4 forums.

There is a problem with the bypass control heater valve of my car Corolla Toyota 2020 It says i have to replace it but it's still running good. I research what this part is about and it says that this is a malfunction in all the Toyota Corollas and RAV4 2019-2021. The message "engine maintenance required" doesn't go away and it doesn't let me see the mile percentage when driving. This problem has been confirmed by a mechanic who installed the tablet and run a test to see what's wrong with it. The car has not been checked by insurance because of this manufacturer malfunction. This all started happening 6 months ago and haven't found a way to replace it and dealership charges over 800 dollars for a mistake Toyota made on all Corollas line. Please help me find a solution. Thank you!

Vehicle was brought to Toyota because of "Engine Maintenance Required" message. We initially thought it was "Maintenance Required" so husband said we may need to change the oil, but it was only a few thousand miles since last oil change. I tried to remove the message but the Toyota Manual did not have any instructions on the "Engine Maintenance Required" message removal. When he left Toyota after changing oil, same message was on dashboard. Husband went back to Toyota and asked them to remove the "Engine Maintenance Required" and was told that there is a coolant bypass valve that must be changed in order for the message to go away. The cost should be around $1,000 and then proceeded to tell him he needed to buy new tires as well. All would total about $2,800. Vehicle has 58K miles and we are afraid to drive the vehicle now until we know what is actually wrong with it. It's suspicious to read all the complaints describing the same situation we have with Toyota. By the way, after we were told about the needed repair, I started getting emails from Toyota about purchasing a Toyota warranty, advertisements in the mail from car warranty companies and phone calls from Toyota salespeople to come and buy/lease a new Corolla and I would get a "great deal"! Is this some scam to generate business? Are Toyota owners being subjected to a "bait and switch" scam? I would like an investigation initiated by your agency. My vehicle is available upon request and our safety is at risk because we truly don't know what is wrong with it and afraid to drive it any longer. If your agency wants to read complaints from other owners, I direct you to read the complaints on [XXX] or Google "Toyota Engine Maintenance Repair" message. It's very much an eye-opener about fraud being perpetrated by Toyota. I can provide any documentation needed when I am personally contacted and requested to furnish them.

I have a 2020 Toyota Corolla. "Engine Maintenance Required; Visit Your Dealer" came on the display after I brought my car to the dealership. I returned to the dealership and was told it was $250 to diagnose the problem. I waited a month later and brought my car back for an 80,000 inspection at the Longo Toyota in Prosper Texas. They diagnosed the problem this time and said they would have to replace the Coolant Bypass Valve and Hose for ~$800 plus labor costs. The risk of not repairing these parts is possible engine failure or fire. I've seen many other discussion forums where people are experiencing the same problem with Rav4, Corolla, and Camry models 2020-2023. These parts are not covered under warranty and would have to pay out of pocket for the repairs. Toyota should issue a recall since many people are reporting these same issues, creating out-of-pocket costs for the repairs for >$800.

Toyota Corolla 2020 Engine Coolant Flow Control Valve
Engine, Oct 21, 2024
My 2020 toyota corolla's warning light which stated "engine maintenance required visit your dealer" came on. When I called the dealership they stated I would need to come in and hook it up to diagnose the problem which would cose me $185 + taxes and fees. Then once diagnosed they would be able to fix the problem. I checked with O'Reilly's autopart store and Autozone which both of their scanners found nothing wrong. So I informed Toyota and they stated they I need to bring it to them because their scanner/tool is the one which will tell us what the problem is specific to my car. But they stated they think it could be a hose related to my coolant system to prevent my car from overheating. They stated to watch the temperature gauge while driving as it may overheat and become dangerous to drive. If this happens or I see any smoke pull over and get out if the car. However they haven't seen anyone have to do this so they think I should be fine but I should fix this problem soon. I asked if that is the problem would it fall under my mechanical breakdown insurance coverage and the dealership stated that if that's the problem yes but if I go through the insurance it will take a really long time to fix because they'd have to file a claim and get paid before doing any repairs. Then they said I'd have to pay the copay and any difference. I was confused as my insurance states I only have to pay my copay. However, I had someone else with a scanner/tool hook theirs up and to see if we could check the actual problem and it did say the error code P268115 engine bypass coolant valve. So, this was the issue. I viewed online that there is a class action lawsuit going on right now for this same problem with 2019-2023 Toyota Rav 4 and Corolla's. Toyota failed to disclose this information to it's consumers and it is not being covered under the power train warranty either. This safety issue with cars overheating is dangerous and costly.
Tires, Oct 12, 2024
All FOUR Goodyear Exhilarate tires cracked and separated from the sidewall on the interior side of the tire. i have one of the four tired saved and available for inspection. With the tire separating at the bead and sidewall on the interior side completely away from the butyl liner inside of the tire, it was a mere miracle that the car actually made it to the repair shop without blowing out, causing an accident which could have been a fatality or at least a very bad accident. The tires were taken to a Goodyear service center and after talking with corporate said it was nothing they could do and sent me on my way. By chance the car was going on a trip and wanted to get the tires rotated and the oil changed beforehand , had he not chosen to do such the outcome could've been terrible. There wasn't any warning of tire failure or loss of air due to the separation. Again, it was only by chance that this was caught and ALL FOUR tires replaced . The tire dealer stated that he hasn't ever seen ALL FOUR completely separate at the exact same location all the way around the tire. It is without a doubt a manufacturing error , old /burnt rubber used in the tire making process.

the check engine light came so i took it to toyota dealership. i paid 300$ to get a diagnostic and they said it was my coolant bypass valve and it was 900$ to fix. warranty doesn’t cover this even tho my car qualifies for the coverages. it’s super frustrating since i bought this car brand new and im having multiple expensive problems. i need to replace the transmission, BRAKE ACTUATOR, oil replacement pan and i had to replace a brand new battery because it exploded after only using for less than a year.

The engine Coolant Valve is leaking coolant, in ordering a new part to replace so yes it’ll be available for inspection. My car Could overheat leaving me or my riders stranded wherever it is that the car stops. I went to Tires plus and they said I had to swap it out but I refuse to go to Toyota so they can rob my money The part has not been inspected by manufacturer, police, or insurance, The only symptom is my coolant runs low sometimes and my engine maintenance screen won’t go away

Engine Coolant Bypass Valve has gone bad and presents a 'Engine Maintenance Required, see Dealer' error message.
Other or unspecified, Engine, Sep 7, 2024
Coolant bypass valve. Becoming persistent in several models of Toyota 2019-2021. Dealerships claim it’s not covered under powertrain warranty because it’s part of the coolant system. Should be covered and customer should be compensated or reimbursed.
