2020 TOYOTA COROLLA Complaints

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

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!

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.

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.

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.

Dashboard stated engine maintenance required- visit your dealer and it turned out to be a bypass coolant valve malfunction per Toyota mechanic specialists.

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.

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
