2020 rav4 coolant bypass valve problem. This is an issue that is been happening in the 2019 and 2020 models even with less than 55,000 miles on it. My vehicle milage is 52,000 and now I'm having this problem and the dealer is charging $700.00 to fix the issue. I thought that Toyota vehicles were reliable but this is ridiculous.

Engine complaints
180 reportsI just bought my 2020 RAV4 in November with the lifetime powertrain warranty. By April, I had a “Engine Maintenance Required” light that would not go away. I took it to the dealership and it was my coolant bypass valve. $800 later, it’s fixed. Not covered under any warranty. Very common issue that Toyota charges a lot to fix.
My 2020 Toyota Rav4 was just diagnosed with an engine coolant bypass valve failure. The leak from this valve could cause engine overheating. This seems to be a well known defective engine component that Toyota appears unwilling to address.

1. The coolant bypass valve failed. I had to pay about $950 to get it fixed because it is a safety issue and was not covered under any warranties. 2. Yes they were. The coolant bypass valve is responsible for maintaining optimal engine temperature. With this part broken it, the engine can overheat as the coolant will not circulate through the radiator. 3. Yes. The toyota dealership informed us they see an unreal amount of people with faulty coolant bypass valves. It is an issue with the part. 4. It was inspected by the Toyota dealership in Round Rock. 5. No there was nothing to indicate an issue. I only discovered the problem because I got a "engine maintenance required" warning on my dash.
