Certain Toyota models in recent years. I brought the 2020 Camry to the dealer this am, and it was indeed the coolant engine valve issue #24TE04 – this link goes to the PDF file hosted at the National Highway Traffic Safety Administration (NHTSA) website. The PDF file has the complete list of impacted model and year.
My local Toyota dealer fixed it at no cost for me – share here for awareness as I think both Camry and RAV4 were top selling sedans 🚘 or small SUVs 🚙 , respectively, during those years.
一般情况下，engine 的灯亮，如果发动机温度正常，不冒烟，其它都正常，应该也还好。但是我也很理解女性司机对这些灯亮感到紧张。这也是我把它给修好的一个原因因为这车主要是我太太和孩子开；另外一个原因是manufacturer warranty cover 了这一项。
Earlier: 好像这个问题是wide spread 的。困扰了我大概一个星期，因为这个warning 一下子有，一下子没。一开始我以为是oil change 的提示：她家的车一般有每五千英里换机油的提示。结果换了机油还是有这个warning.油管上有巨多的相关视频 here are couple YT videos – DIY: Replace Toyota RAV4 Coolant Shut-off Valve • Easy Repair Step-by-Step Codes P268111 & p268115 and Free Toyota Coolant Leak Fix | Dealer Extends Warranty For Coolant Bypass Valve . 一个原因是Camry 和RAV 4在这里销量是排在前的。我想很有可能是丰田在设计和制造上的缺陷。
I also made two YT Shorts video, here is one and two.
PS: some good YT videos on Toyota maintenance: These JAPANESE SECRETS Will Make Your Toyota And Lexus Last Over 700k Miles (Japanese Motors) and Toyota Owners Stop Making These Critical Mistakes! (The Car Care Nut)
PS 2: The Car Care Nut has a video How To Get Over 300k Miles Out of Your Modern Toyota on Toyota maintenance to keep the car last longer.
Btw, he has a car shop TCCN Automotive Inc. in Chicago, and I just realized St. Louis has a similar mind car repair shop too – Jamco – (Japanese Auto Maintenance Co) – here is their Google review and I came across one comment:
