2020 Toyota Corolla

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.

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.

The automatic emergency breaking and forward collision warning failed to alert and turn on and I wrecked into an object. My life was put at risk and I wrecked my car. The problem has not been reproduced or confirmed by the independent service center. The vehicle is currently being inspected by insurance estimator. There was no other alerts or messages to alert prior to collision.

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.

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
