If I don't drive the car for 1 to 2 weeks, the car's 12v is completely drained of power and the care needs to be jumped, otherwise, it will not start. This is consistent. I've taken this to several Toyota dealerships and they all have reported my 12v battery is healthy. However, Toyota is aware and is charging for the fix, labelled as T-SB-0089-21. The known issue is a piece of electronics in the car that continually drains power because it does not properly shut off. This should not be a paid fix. This should be a recall. When the car is jumped and the car finally starts, it reports a message saying something about some safety features not available. The car needs to be moved every 2 weeks due to mandatory city street cleaning so at least once every month the car needs to be jumped if not used the week prior.

Toyota made a defective coolant valve in their 2019-2021 cars that leaked spontaneously in these vehicles. Over 950,000 cars have been affected to date, including my 2020 Rav4. They are aware of the issue and made a customer support program for this issue which led to engines overheating/electrical code problems, which can cause a severe safety issue if left unrepaired. The program however has a limitation until November 2025 or 100,000 miles whichever comes first. When I was alerted of this, I brought my car to the dealer for service, but they wouldn't replace the part because it wasn't leaking too much at the time to need repair. However, just 4 months after the primary coverage expired, my engine code went off and when I brought my car, the coolant valve turned out to be defective and leaked into the electrical wire harness which then also had to be replaced in addition to the coolant valve. The repair cost was $1200 and both were required to keep the car driving safely and reliably on the road. Because my car had 120,000 miles and the known issue presented after Nov2025, Toyota refuses to cover the service, although it is a known manufacturing defect. Toyota is committing fraud to avoid covering this safety issue. The repair is expensive and if left unrepaired, the cars can spontaneously catch on fire on highways and in parks leading to wild fires and endanger others on the road. The toyota technician specifically informed me the issue was similar to other cars and known and the defect led to the destruction of the wire harness. To avoid a safety recall, Toyota reached a private settlement against class action lawsuit and created a limited CSP to avoid covering the defect in cars like mine to maintain their reliability status in consumer reports so cars like mine with little higher mileage won't be reported. It is fraud. I believe they are skipping on consumer repair bills that consumers on entitled to for their manufacturing defect.

When trying to start my vehicle this morning, the car was having a noticeable issue the minute I turned on the vehicle. It was making some weird noises under the hood, and it was starting to lose power. Then the engine would cut out and a warning would appear on my dash that read, "Engine Stopped, Steering Power Low" Thank God this happened while I was at home. What if this had happened while I was driving down the road, at a red light. I would have been a sitting duck in the middle of the road and would not want to put my kids or I in jeopardy of being hit.

Shorted Coolant Bypass Valve, only 14500 miles on my 2020 Rav4, Class action Suit and dealerships want you to pay $800-$1000 to fix problem with a leaky defective plastic poorly designed valve that eventually leaks into the electrical connectors and shorts circuits the valve. There is no recall for this fix and Toyota won't honor the repair. This is a common issue and Toyota Turns a Blind Eye. Error Message: Engine Maintenace Required Call Toyota Dealership. I Did and they give me a song and Dance stating there is no recall for this issue. If i run the heater in the car the message for a few a minutes, then shut off vehicle maintenance warning will reset, once I turn on the AC it will come back on. So, I guess I have to keep the heater on all summer.

The CarPlay disconnects constantly during every drive. It’s is extremely dangerous because when my directions are being displayed the navigation cuts out, and you have to fiddle with your phone to attempt to reestablish the connection.
