Just received Engine maintenance required message that can not be cleared. I pulled in to my local firestone who looked up the error code p268115.

Hybrid Harness Malfunction. As reported on FaceBook by my wife to [XXX] of LIA Toyota: "Well my husband's RAV 4 wasn't safe and you knew it. And corporate knew it. You are in the business of saving lives by informing your customers when you find a defect in your cars. This faulty harness is dangerous. And the repair is costly and there aren't many of these parts available to make the repair. You put my husband and countless others in danger. Shame on you." Not only has the problem been confirmed: On May 11th, I received a letter from TOYOTA Motor Sales, USA, Inc. entitled, Certain 2019-2022 Model Year Rav4 Hybrid Vehicle (AWD Only) Coverage for High Voltage Floor Under Wire Harness and Rear Traction Motor Cable Corrosion CUSTOMER SUPPORT PROGRAM 22TE09 NOTIFICATION... There was a YouTube Video made by [XXX] about this problem A YEAR AGO entitled, "CableGate," AND an article at TorqueNews. (I have links if needed) The vehicle has been inspected and repaired by LIA Toyota in Rockland County. OVER $5,500 that I'm looking to get a FULL refund. LIA gave me back $1,000 for over-charging me. I want the FULL refund from Toyota Motor Sales, USA, Inc. A warning lamp/message appeared on May 6. I have emails, reports to corporate & screenshots of conversations with LIA service...all lasting almost 2 months. Toyota Motor Sales, USA, Inc. and LIA Toyota BOTH new of this problem a year ago BEFORE they sent out the letter. The letter states they would repair it for free if under 100,000 miles. I had 114,000, BUT...if I knew a year ago, I would have brought it in...UNDER the 100,000 miles, and got a FREE repair. Thank you for helping me get a full refund and for helping others with this same problem. USA Toyota owners NEED TO KNOW THIS!

I was driving my 2019 rav 4 and a warning came on my screen that stated “ engine maintenance required. Visit dealer.” No check engine light came on just this warning that would not go away. I went to orileys to see is they could tell me what was wrong and they were unable to read it since it was not a check engine light. The orileys employee told me I had to take it to a Toyota dealership to find out exactly what was wrong with it. I contacted my local dealership and they confirmed that it was a coolant bypass valve that failed and that he has seen this warning pop up on at least 10 Rav 4’s and that every time it is the coolant bypass valve that has failed.

Vehicle had been in for routine maintenance 6 weeks prior. Around 46k miles, the check engine light came on requiring me to bring it back to the Toyota dealer. I wasn't able to bring it to the dealer for about 6 days after it came on due to appointment availabilitly. Once I brought it in, they told me the coolant bypass valve had a circuit short and needed to be replaced. This part was replaced and is unable to be inspected.
