What 625 owners told NHTSA about the 2020 Toyota RAV4 Plug-in Hybrid

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 wiring harness to the lithium battery is corroded, and it is unregulated. My repair shop said the car is unsafe to drive because of the amount of unregulated electricity in the battery. Also, the cruise control doesn't work. My repair shop says this is happening to other vehicles. Parts and labor total almost $7,000.

at only 55k miles my 2020 toyota rav4 has shown an “engine maintenance required” sign. not to be mistaken with general maintenance. apparently this is a widely common issue where brand new toyotas are having cooling bypass valve issue. however concerningly so, because there are no recalls for this problem yet seemingly every rav4 has this problem? how is there no recall, everyone is paying out of pocket for essentially poor manufacturing, its outrageous, also considering the part itself is under $100 but some dealers are charging anywhere to $600-$1300. it’s predatory and outright wrong.

It's been a year that this situation is still under a recall and there is no remedy. Keep receiving constant notices and every time I call its something new and yet they still don't have a remedy. I was told last year not to have anyone sit in my passenger seat until a remedy is found. I feel unsafe and have been financing my Toyota RAV4 since August 2020. My recent call they wont have a remedy June 2025 which I told believe being when I called last year I was told that the remedy would be September 2024. So basically they are telling me that if I were in an accident that the airbags will not go off is someone is sitting in my passengers seat being that what needs to be fixed is the airbag sensor. To be told that I shouldnt have anyone in my passenger seat until this is fixed is insane.

Wire harness failure according to the Toyota dealership representative I spoke with after inspection on 12/18/24. Rep said this is a known issue with certain years and they will cover cost of replacement. Previously, I had received a message stating, "Hybrid System Malfunction, Visit your Dealer" but could not get an appointment until 12/18. The dealer rep said they needed to order parts to fix the wire harness issue and that I would be okay taking the car and bringing it back when parts were in. The day after the inspection (12/19) I was in a Walmart parking lot and my car started but I could not get it to drive or reverse. A message stated "Vehicle not ready to drive" and "No power to rear brakes". If I put the car into drive or reverse and stepped on the gas, the car interior lit up and the dinging sound (usually associated with unbuckled safety belt) was heard. I had my safety belt fastened. My car could be put into neutral and had to be towed to the dealership. After looking into the issue, I found out that the car could had died while I was driving it resulting in loss of power brakes, etc. I live in a more rural area and could have been stuck with out cell reception, etc. This should be a RECALL and they never should have let me leave the dealership in my car. Note: As of today (12/20) the dealer rep stated they will cover all towing costs and cover a loaner vehicle for me. My dealership is very helpful BUT this could be a serious issue for someone else. Google "Rav 4 Cablegate" for more information.

The Rear Hatch started to get stuck. It is automatic so you would normally press a button to open and close and it would slowly move up or down and close shut on its own. When the issue started, it would "pop open" but stay stuck to a point where I would need to manually lift it open. (hitting my head on it often) Right before I took it to the dealership service, it would not close properly. While it seemed close, the notification showed it open therefore, not allowing me to lock my car and the lights on the car would need to stay on while car was parked and off. Driving home, the "open door" notification was beeping non-stop. Once again I had to open and close manually until it was considered "closed" Brought the car into the Toyota Dealership to assess. They found that the power lift gate hinges on the door were coming off and it needs to go to an Auto Body for realignment. I performed research online and found this to be a very common issue with the Toyota RAV4's. I have had leased 2 RAV4's prior to this one and never had a problem (those were manual hatches) [XXX] [XXX] My car has 33k miles on it although this issue (not as severe) started a while ago.

I replaced my battery a little over a year ago and have come back to my battery completely dead and unable to turn the engine over. The first time it happened my vehicle had sat for 4 days. It has done it sporadically and sometimes within 2 days of incidents. I have checked to make sure no components were left on to cause this issue. It has left me stranded multiple times.

I have had a Service Engine message on my dash that would return within seconds of my hitting the button to signal I received the message. When I took the vehicle to the dealership I was told it was a leaking coolant bypass valve and would need to be replaced. I was told the cost would be $215 plus three hours of labor. The final cost was $240 for the parts and $709 for the labor. The vehicle only has 31,209 miles on it. As I have researched the part, I have found numerous people have had the same issue within a similar range of mileage.

52,000 miles, and was just informed the coolant bypass valve has failed. This is apparently an issue with ALL 2019~2022 Toyota Rav4 vehicles. It was a known issue to Toyota, using substandard parts. It results in an error message that cant be turned off, masking all other messages, and can only be fixed by a dealer for over $1,000 in costs.

PARASITIC BATTERY DRAIN DEFECT complaint: prior to 07/16/2024, I received a "low voltage" error on my Toyota RAV4 screen a few times. On 07/16/2024, I took it to the dealership. My battery tested "good" and the Toyota dealership charged me 39.95 to tell me that everything was working well on my vehicle. The very next day (24 hours later), 07/17/2024, my vehicle would not start and had to be towed to the dealership. The tow truck driver told me the battery was "dead" (based on his measurement) and leaking acid (based on a smell). Toyota charged me 272.52 to replace the battery on 07/18, that was supposedly "good" two days prior. This is a known issue to Toyota, part of a class action lawsuit referred to as "Parasitic Battery Drain Defect." This is dangerous since I was stranded with a car that would not start in a summer day of high heat, but could have been much worse in other circumstances. The tow truck driver told me that the battery acid could be dangerous. Toyota should be providing a fix and a recall, but they had no solution for me other than a new battery which is a "quick fix" (but not a real solution) as described in the Class Action lawsuit documents.
