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.

The wipers keep stopping during use. I have to switch speeds to get it running again. Very dangerous when raining.
Power train, May 8, 2024
Engine coolant valve is broken. Part of power train as it cools circuits for the power train.
Engine, May 7, 2024
The Engine Coolant Bypass Valve Short in the vehicle has malfunctioned. This appears to be widespread issue not only in the Corolla, but in the Camry and RAV4, and appears to affect model years 2019-2024. This issue caused coolant leakage, has the potential to cause issues with the engine, and affects the A/C/Heating systems as well. There were no warning signs prior to the failure, and the car had just passed a multi point inspection 4 days prior to the failure. The problem has been reproduced by my local Toyota dealership.

At 4 years and 1/2 old car 2020 Corolla XSE an Engine Maintenance Required SEE DEALER light turned on. Did diagnostic with OBD 2 scanner at two locations auto body shop and Uto zone. Nothing appears. It is in fact a NEEDED future recall since thousands if not more people have encountered the same. It is a Coolant By Pass Valve. Cost is only $99.53 + tax at dealer. Problem is that should be under warranty or extended warranty or recall. Dealer likes to charge $800 (180-200 for diagnostic, $110 part, $400 labor. Part only takes 30 minutes to install. I should be able to buy at dealer for $110 and have them install for free or pay 30 minutes of work time = $85. 1 hour is about $175. So instead of trying to be billed $800 I should only be billed for $85 labor (30 minutes) + $110 part = Brand total of $105 USD. My daughter [XXX] and I, [XXX] (dad) bought the car at Longo Toyota El Monte, CA 91731. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine maintenance repair On display vehicle not in motion on radio screen
Engine, Apr 29, 2024
Known issue in certain Toyota models and years that the coolant bypass valve fails causing a "Engine Maintence is Required. See Dealer." Toyota is well aware of the issue but has yet to fix the problem as driving with a failed coolant part for too long could cause overheating.
Engine, Apr 27, 2024
My engine maintenance required screen came on in my car. When I ran the diagnostic, they stated that the coolant bypass valve needs to be replaced in order to prevent the engine from overheating. This seems to happen on all of the 2020 and 2021 Toyota Corollas.
Other or unspecified, Apr 24, 2024
Maintenance required please see dealer message pops up and cannot be dismissed. Coolant sensor bypass valve is damaged.
Electrical system, Engine, Apr 24, 2024
An engine maintenance required popped up in the vehicle and was unable to be removed Took the vehicle to get checked at a Toyota dealership and they advised it was the coolant valve bypass was faulty
Engine, Apr 22, 2024
Warning display message “Engine Maintenance Required Visit Your Dealer”. After diagnostic at the dealer, coolant bypass valve failed and needed replacement with hefty, almost $900.00 for parts and labor cost. Did research online, and it seems that more vehicles from the year 2020-2021 have experienced the same issue at 30-55k miles, my car is on 106k miles. Please do a recall for this issue and extend warranty to $200k miles. This car should not have this sort of issue!

engine coolant bypass valve issues under 70k miles
Engine, Apr 18, 2024
The engine coolant bypass valve needed replacement at around 70,000 miles. Similar replacement have been needed in other corollas models of the same year.
Other or unspecified, Apr 16, 2024
The "Engine Maintenance Required, Visit Your Dealership" is displayed. The oil has been changed and tried to reset the warning as it states in the owners manual but it wont reset.

Engine maintenance required light comes on and it wont go away. Happened around 65000 miles. It is cracked engine coolant bypass valve. It is happening to all toyota corolla 2020s. Dealer is asking $1200 to fix it.
Visibility/wiper, Apr 16, 2024
The windshield wipers seize up. On the intermittent setting, instead of wiping every few seconds they sometimes wipe 3 times in a row and then stop in the middle of the windshield sometimes obstructing my view. They sometimes start back up on their own and sometimes are stuck there until I switch to a higher speed and lower speed for the windshield wipers. It becomes a game of trying to restart them while driving while it's raining. It's dangerous.
Engine, Apr 15, 2024
Engine coolant bypass valve failed at 36,981 miles.
Electrical system, Engine, Apr 13, 2024
Dashboard stated engine maintenance required- visit your dealer and it turned out to be a bypass coolant valve malfunction per Toyota mechanic specialists.
Engine, Apr 10, 2024
Experience with a faulty Coolant Bypass Valve. Read enough information of this being a problem with newer toyotas (RAVs, Camrys, Corollas, etc.). Cannot get rid of Engine Maintence Required notification on dash which pops up every 10 seconds when I’m driving after I dismiss it. This specific notificaiton is also NOT in the Toyota Manual whatsoever, and no it is not the Maintenance Service Required notification that comes up every 5,000 miles for basic check up.
Air bags, Apr 10, 2024, crash
I was in a car accident where someone hit us at a high speed from behind. Unfortunately the air bags malfunctioned resulting in my face being busted on the front dash. The car gave me a malfunction warning when they didn’t deploy

Engine maintenance required People on internet saying that i need to change the coolant bypass valve
Other or unspecified, Mar 29, 2024
“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.

Engine coolant bypass valve becomes faulty at low mileage
Engine, Mar 21, 2024
My 2020 Toyota Corolla had a warning light turn on, on 3/20/2024. The warning read "Engine Maintenance Required". I looked up this issue and read that many people were having similar issues with the coolant bypass valve. I took my car to my local Toyota dealership and they confirmed it was the coolant bypass valve. The risks included in this failure can be overheating and engine damage.
