Consumer Description
I discovered that my 2020 Toyota Corolla SE has a Coolant Valve Bypass malfunction coded "p2688115". I have also discovered this a prevalent issue after you hit 70,000 miles. There are forums all over the internet with complaints about the same issue as mine. I did some research and found no recalls. With this being such a common issue for no reason, faulty equipment. The car has been inspected by a Toyota dealer in Bradenton, FL because we had thought the service vehicle message was for a tire rotation. They scanned the vehicle and discovered the fault code "p2688115" after trying to reset it numerous times. The senior tech was the one who scanned it. He knew the exact reason why it was not clearing before scanning the vehicle. He only scanned it to solidify his hypothesis. I then spoke to the service team, they wanted me to bring it in for a diagnosis that would cost $85.00 if my warranty did not cover it. The cost of the part was estimated at around $150.00 plus labor and taxes. It was over a $400.00 repair. For a repair as such, this needs to be recalled. The warning message never went away, if you tried to clear it to view the screen you had about three seconds before it came back on. It is a major safety risk for those who wear glasses and drive at night. I use the screen to keep myself safe and maintain my driving speed. This warning message came on around 70,000. Some so many other individuals have experienced and complained about the same problem. This needs to be escalated. I am not allowed to utilize the safety features my car has to offer. Please take action and commence an investigation.
