My 2020 Corolla XSE has been displaying an "Emergency Maintenance Alert" for over a month covering the middle portion of my dash. When running the code it indicates "Coolant Valve" defect. Upon further research while trying to obtain a replacement part it looks as though multiple people are having an issue with the same part.

The car will need a new coolant by-pass valve ($663 installed). This is a problem that seems to be affecting more cars than usual as it is in many websites and social media portals, but it's not recognized to be recalled!! A $70.00usd part for $663.00 installed??

The coolant valve in the engine began malfunctioning and leaking next the the battery. I took it to the dealership and they said that this was a common maintenance issue, but it is do to the part being faulty overall. This is a widespread issue with this make and model of the vehicle and the part has not been recalled. Leakage could possibly cause the engine to overheat and the result could be catastrophic.

At 55K miles for my 2020 Toyota Corolla, the Engine Maintenance Required notification popped up on my screen and is not removable. Upon further verification numerous 2020-2021 corollas have been having this issue at similar amounts of mileage. It is a faulty Engine Coolant Bypass Valve that needs to be replaced. If I were to take it in to a dealership, they would charge $500+ just as they have for many others when it should really be a recall. As of now I have not taken it to be inspected due to fear of steep labor costs. My safety is at risk because if this does not get replaced my engine will overheat causing total failure of the car, and as a 2020 model with such low mileage, this is ridiculous.

My son and daughter in law moved from California to Georgia due to military duties in Hinesville Georgia. They drove their 2020 Toyota Corolla from California to Georgia. They paid the fee to obtain their 2024 registration sticker but got denied by the DMV in California due to a recall on this vehicle. My son took the vehicle to Chatham Parkway Toyota in Savannah Georgia to fix the recall. He received documentation that the recall has been fixed. My daughter in law took this documentation to the DMV and they said it was not sufficient, we needed to provide the original pink copy of the recall. Chatman Parkway Toyota never gave my son the original copy. Where can we obtain this so we can receive our registration sticker? Can you please help us out and contact Chatham Parkway Toyota to see if they even fixed the recall problem or not and why they did not give my son an original copy of the fixed recall situation. It has been a struggle to obtain the registration sticker when the recall was a problem. This situation has been very stressful due to an expired registration and not being able to drive u til we receive the correct sticker. Please help if you can. Thank you, [XXX] . [XXX] .

Check engine light is giving a false positive. There is something wrong with the coolant bypass valve. I checked online and this is not an isolated event.

I own 2020 corolla le. It has 50k miles. There is a message that keeps coming up in the infotainment screen and hinders the navigation information especially when i am looking for directions and evey second counts and not being able to act when the exit appearscan cause an accident. The message is caused by a dcm failure. Toyota should never allow a message like that pop up every time on the navigation screen. It keeps saying “ device connected not supported “ every few seconds.

“Engine Maintenance Required Visit Dealer” keeps popping up despite engine being fine. Another scan by my mechanic determined that the cooling bypass valve is having an issue/keeps getting stuck and triggering the maintenance alert to keep going off.

There is a thing that’s happening to a lot of Corollas and I think RAV4 and some cram it’s called engine maintenance required and a lot of mechanics don’t know what that means so you have to take it to the dealership to get it fixed and it’s like a $900 fix and it’s been happening to a lot of vehicles around 35,000 miles. It’s called the coolant bypass valve. There is hundreds of YouTube videos about it and people complaining about it on forums.

Around 40k miles I received an Engine Maintenance Required warning. After some research Engine Maintenance and Engine Service Required are two very different indicators. I received and P2681 code meaning the electrical coolant bypass valve had failed unfortunately one can’t tell if it’s stuck shut or open this could lead to one’s care over heating and or damaging one’s engine. After some research I’ve come to find out most 2020-2024 corollas have been having this issue tends to happen about 30-50k miles

Precollision System Malfunctioning and Hybrid System Malfunctioning warning signs on dashboard won’t allow the car to move or driven at all. I read reviews where people with the same warning signs on dashboard got their car stalled in the middle of the road. My vehicle only has 81,000 miles on it and Toyota dealership warranty states it’ll cover the vehicle up to 150,000 miles EV hybrid but now they are stating the car is not under warranty
