Coolant bypass valve. Code is P2681, part will fail and vehicle will consistently display a Engine Maintenance Required Visit Your Dealer on the MID. Dealerships will try and charge 500+ to repair it when the part is under 100+. Problem started to appear since end of March. It's May 15th as of this report. Upon using an OBD tool this is the following message: "STATUS CONFIRMED / PENDING - ENGINE COOLANT BYPASS VALUVE 'A' CONTROL CIRCUIT/OPEN : CIRCUIT SHORT TO BATTERY OR OPEN". Part has NOT been inspected by Toyota, nearby service centers are scumbags and will charge a fortunate to fix it.

Odometer Fraud. The contact purchased a 2020 Toyota Corolla Hybrid. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 87,950 and at the time of registration, it was discovered that the mileage was 297,000.

ENGINE
I received a "voluntary Customer Support Program" letter from Toyota saying that a small engine coolant leak can occur that "can allow coolant to drip on other parts of the vehicle. This can cause 'Engine Maintenance Required' to be displayed or cause the A/C not to function normally." Then it concludes that repair with a new "flow shut-off valve" will fix the problem, "under the terms of this Customer Support Program." I thought this was a recall and took my car in only to find that they wanted nearly $700 for the repair, because I did not have an extended warranty. When asked whether this could cause a safety problem if unfixed the reply from the Service Advisor was yes -- the coolant leak could potentially cause the engine to seize up on the highway. I was shocked that a defective part in the car I purchased new for $20,000 plus would not be replaced free of charge. I have put less than 16,000 miles on the car and now I find the resale value is essentially zero. And I now may be driving a potentially risky vehicle that could crash or leave me stranded somewhere. I feel there should be a repair at no charge.

ELECTRICAL SYSTEM, STEERING, FUEL/PROPULSION SYSTEM
after shortly pumping gas, I received a alert on my car that I needed to check my fuel cap, after checking fuel cap I proceeded to drive on the highway during this time a multitude of sensors started to go off on my car, and it started to drive weird there were light such as my interlock, being deactivated, parking, brake, deactivated, malfunction of VSC, collision deactivated. Then suddenly while driving at an accelerated speed, and trying to slow down, my engine turned itself off, and I was not able to re-crank my car. There is an active recall with Toyota for the fuel pump, which I was told by Toyota was the issue, but due to my VIN not being associated they would not repair as a recall

POWER TRAIN, ENGINE
Drive start control malfunction occurred when turning the car on. Second time this has happened. First time was a charcoal canister and engine coolant valve. It was replaced under warranty at 50k miles but now at 96k miles the dealer says it is not covered under the extended warranty. Not sure how this problem happened.

UNKNOWN OR OTHER, ENGINE
Once I parked my car and turned on the A/C a couple mins later I received a warning message on my car screen saying “ Engine Maintenance Required Visit Your Dealer”. After having my car for 4 years I’ve never received this message till now (04/22/25). I thought it was because I needed an oil change but I was wrong because my oil is good. I checked my car and saw that the issue is the “coolant bypass valve”. I don’t even use my car that much for this to happen. I saw this is a common issue with a Toyota Corolla 2020 but the dealership does not want to fix this issue for free.

The "Engine Maintenance Required" message on a 2020 Toyota Corolla SE keep coming on after I have reset numerous time. The "Engine Maintenance Required" message on a 2020 Toyota Corolla SE typically indicates a problem with the coolant bypass valve, not the regular maintenance schedule. This message is distinct from the "Maintenance Required" light that usually prompts oil changes. The coolant bypass valve issue often results in a DTC code and may require replacement.

ENGINE
I own a 2020 Toyota Corolla, and without any prior warning, the “Engine Maintenance Required” message appeared on my dashboard at approximately 79,575 miles. There were no unusual symptoms—no overheating, strange noises, or performance issues—before the light turned on. I had my vehicle inspected by Golling Toyota of Warren, where they diagnosed the issue as a faulty Engine Coolant Bypass Valve. I was informed that the valve needed to be replaced and flushed. The total cost of the repair was $932.21, which I had to pay out of pocket. Because the message specifically said “Engine Maintenance Required,” I was concerned that it could be a serious engine issue. Out of caution, I avoided driving the vehicle until it was inspected, as I didn’t know whether it could result in engine damage, performance failure, or a sudden breakdown while on the road. The fear of an unknown engine-related malfunction created a genuine safety concern for me and others —especially since the warning came without any prior symptoms. I later learned that the problem was tied to the Engine Coolant Bypass Valve, which is known to fail prematurely in Toyota vehicles. This failure can affect engine performance and temperature regulation, increasing the risk of engine damage or failure while driving. There is already a class-action lawsuit concerning this issue, yet Toyota has not issued a recall. Owners like myself are being left to pay out of pocket for a known defect that poses real safety risks. I’m submitting this complaint in hopes that Toyota will be held accountable and that the NHTSA will take appropriate action to protect consumers from this recurring and potentially dangerous defect.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The anti-lock brake system (ABS) malfunctioned when the vehicle was still very new, with only 25,000 miles. Diagnostics from two independent service centers confirmed that the ABS electronic control unit is failing due to an external failure. Both specialists stated that such a failure is highly uncommon and is a clear quality issue related to the electronic components. A critical system like ABS should not fail this early, raising serious concerns about the durability and reliability of the vehicle’s braking system.

Approximately one month ago the clutch pedal on my manual 2020 Corolla went all the way to the floor and stuck in place. Had it towed to my mechanics shop and it took them nearly 2 weeks just to get a slave cylinder to replace the defective part with. Fast-forward a week later and exactly the same thing happened. According to several different threads I have read online, this seems to be a problematic situation with the manual Corollas. Hopefully I will not experience any further problems however it appears that the defective slave cylinder part is to blame.
