I have experienced a message saying 'Engine Maintenance Required' and after experiencing the same instances as many people have online, it seems the engine coolant bypass valve is faulty and needs to be replaced. No code can be read using a code reader either.

My airbag sensory notifications keeps coming on. When I start my car normally it isn’t on but once I start driving the notification will come on along with the ding noise it makes when you don’t have on a seat belt. I notice there was a recall on this issue for the later model Corolla and wanted to see if possibly this could be considered for the 2020 Corolla’s.

On June 19, 2025, I was driving and out of nowhere, there was a warning notification that said "A warning light was turned on. Would you like to call an operator?" On the digital cluster, there was a message that said "Engine Maintenance Required - Visit Your Dealer. Mileage noted down was 79,632. I asked around for some insight and people are telling me it's the water/coolant bypass valve that's leaking and the Op code is 24TE04R1. Will this be a covered service?

The engine maintenance required message appeared on the dash. I was travel from work to home (about 40 miles). I pulled over immediately at a store, left my car and walked over a mile to the mechanic shop down the road (in 95° weather with a knee that has been through 3 surgeries in less than 5 years). The gentleman took me back to my car. Followed me as i took my car back to the repair shop since it was close and did not have any lights on the dash and I was not overheating. He plugged a reader in it and the error was a coolant bypass valve issue (i can't remember the exact verbage). I purchased a replacement valve 6-17-25, along with toyota coolant. I am having to wait and save up the money to have the valve replaced at the shop got the message code from. I can not afford the dealerships cost to replace the valve. The valve and coolant was expensive in itself. I have read many forums and blogs. Toyota knew there was an issue and I am requesting my reimbursement for the cost of replacing a part you knew was faulty.

The windshield wipers stop in the middle of the windshield at times when set to intermittent. Sometimes they will not shut off when they are turned off. This can be a hazard while you are driving and you never know when it will happen.

I have an error that appeared displaying “Engine Maintenance Required” after some investigation snd research, I have noticed that this is a common issue associated with the OEM Engine Coolant Bypass Valve. This occurred as I was driving home from work when I was driving down the freeway, I did not run into any obstacles or have an accident, it appeared out of thin air.
