I have a 2020 Toyota Corolla. "Engine Maintenance Required; Visit Your Dealer" came on the display after I brought my car to the dealership. I returned to the dealership and was told it was $250 to diagnose the problem. I waited a month later and brought my car back for an 80,000 inspection at the Longo Toyota in Prosper Texas. They diagnosed the problem this time and said they would have to replace the Coolant Bypass Valve and Hose for ~$800 plus labor costs. The risk of not repairing these parts is possible engine failure or fire. I've seen many other discussion forums where people are experiencing the same problem with Rav4, Corolla, and Camry models 2020-2023. These parts are not covered under warranty and would have to pay out of pocket for the repairs. Toyota should issue a recall since many people are reporting these same issues, creating out-of-pocket costs for the repairs for >$800.

Engine maintenance light came on after turning on air conditioner. Vehicle information: warning light came on at 56,800 miles on 2020 Toyota Corolla, no after market modifications to vehicle. I took vehicle to Toyota dealership for diagnostic testing. Conclusion: coolant bypass valve faulty causing leaks (this can cause overheating, stalling, increased emissions, and total engine failure and also allows coolant to leak into and damage surrounding engine components, including a vehicle's electrical system, the complaint relays). Fortunately, I PURCHASED AN EXTENDED WARRANTY when I bought the vehicle new, which covered the repairs. The faulty coolant bypass valve was replaced at the Toyota dealership. Had I not purchased the extended warranty, I would of been out of pocket for said repairs.

The car is at 58,125 miles and I’ve had a “engine maintenance required, please take to dealership” message for the past 3 months which will not go away and is just stuck on my dash. An OB2 port scanner shows nothing wrong, but after a diagnosis at toyota it appears I need a new engine coolant bypass valve. As it turns out, many other corolla, rav 4, and camry owners of the same generation (2020 and up) also receive the message and need to get the coolant bypass valves replaced around 30k-60k miles.

Front passenger side brake caliper was rusted and seized. At the time of this issue the car is two years old and had 40k miles. The car has lived its entire life in western North Carolina with me being its only owner. It has never been driven in salty conditions other than twice to the beach. The dealership refused to fix this safety issue under the platinum warranty I purchased because it is "Enviromental". This is a major safety concern. I have a 1997 suburban which gets drove in salty conditions every winter and has never one had an issue with its calipers or any operational part rusting.
