2020 Toyota RAV4 electrical system problems

“Vehicle electrical failure when Driving with the automatic start/stop option turned on Vehicle shows a low voltage abnormality that kills all my electrical components including battery, sometimes it happens while driving on the Highway at 70 speed”

“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.”

“Odometer Fraud. The contact purchased a 2020 Toyota Rav4. The contact stated that it was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 59,475. The contact stated that while his father was driving the vehicle, the vehicle stalled several times. The contact's father was a mechanic and was able to repair the vehicle. It was later discovered that Carfax reported the vehicle mileage as 176,009.”

“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.…”

“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.”

“Bought the car with 114k on it now with 115k and I brought it in to Toyota because I have a “engine maintenance required” on the dash now they are trying to charge me almost $1000 because my car has over 100k miles on it and they said they won’t cover it.”
