After a few days the \"Engine Maintenance Required - See Dealer\" notification appeared. See as it was purchased very recently, I assumed this was the oil maintenance light, and reset it. Later that day, it came back, and I reset it a different method under the assumption I did it wrong. The next day it was back, and that is when I realized it must be something else. So I started doing some research and found lots of other people have had this same issue: 2020-21 Corolla, greater than 30k miles, usually less than 60k, and while the Check Engine Light *DOES NOT TURN ON* the car is throwing an error code: P268115 - Engine Coolant Bypass Valve. Sure enough, I have the codes pulled and I have that code showing up. So I took it to the local Toyota Dealership. They stated that the issue was not a warrantable, so I would likely have to pay out of pocket. After a slight fuss, they agreed to fix it as a \"one-time goodwill gesture, performed in the interest of customer satisfaction...\" So in the end, they did fix it; I did still have to pay for a diagnostic of the issue which is frustrating, especially since I was dead on in my analysis of the issue.   To answer the guideline questions:  Engine Coolant Bypass Valve Leaking engine coolant could cause the engine to overheat, which can lead to fires, not exactly ideal. It can also cause electrical shorts, leading to more issues. Yes. Lancaster Toyota confirmed the issue. Yes, Lancaster Toyota confirmed that the part was faulty. They appeared shortly after buying the car. There were no error lights like I'd expect, but there was the constantly appearing \"Engine Maintenance Required - See Dealer\" message which the Owner's Manual states is simply the 5000 mile Oil Change warning. Hidden behind this message is the error code P268115.","products":[{"type":"Vehicle","productYear":"2021","productMake":"TOYOTA","productModel":"COROLLA","manufacturer":"Toyota Motor Corporation"}]}]}
