general problems of the 2020 Toyota RAV4 - part 1

The contact owns a 2020 Toyota Rav4. The contact stated that while the vehicle was parked, coolant was observed leaking from the engine compartment with no warning lights illuminated. The vehicle was taken to the dealer where it was diagnosed that the engine casing had failed, and the contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but denied the engine replacement request because the vehicle had previously been serviced by an independent mechanic for engine maintenance. The contact stated that the failure was related to NHTSA campaign number: 20v064000 (engine and engine cooling). The approximate failure mileage was 34,678.

Sudden and complete failure of the water pump causing an explosion of the part. While traveling down the interstate, put lives in danger due to sudden jolt and rapid deceleration. Recently brought the vehicle in to correct recall on the engine coolant bypass valve. Issue with the bypass valve hastened the deterioration of the water pump to the point of failure. Told by mechanic that this is a known issue that just happens with Toyota’s. If this is a known issue, then it seems to me there should be another recall on the water pump. Plastic parts with highly corrosive liquids at high temps do not mix. Toyota needs to fix this costly issue.

Engine light shows on in dash. Stopped to fuel up car stalled, would not restart diagnosed fuel pump no prior history of engine issue.

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.

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 contact owns a 2020 Toyota Rav4. The contact stated that while driving at various speeds, the vehicle would hesitate to maintain automotive power.

Engine maintenance message appeared on my dash. I took it to big o's tires and service a car repair service provider. Upon connecting to the car and inspecting they told me it was a faulty possibly leaking engine coolant valve. The cost to repair is $916. This may cause the engine to overheat and possibly fail due to overheating. This can be very dangerous because it will happen if it does happen while driving which could cause an accident. I have not fixed the issue yet due to a lack of funds but will have to fix it as soon as a get paid because I drive my family in this car and cannot risk catastrophic engine failure. Please have Toyota recall this part as it is a very common failure amongst 2019-2023 Rav4s. A class action lawsuit is underway due to how often this issue arises. Thank you for your time.

I was driving the car with no issues on July 13th- made two 30-minute trips with no issues the same day. During a 15-minute drive, the car was fine until I was at an intersection 12 minutes into the drive (frederick rd and centennial ln in ellicott city, MD). I was stopped at the intersection for maybe a minute, and when the traffic light turned green, I released my brake and went to accelerate when I got the following display message: "engine stopped steering power low. " the engine turned off, and I couldn't get the car to budge in drive or reverse. When I tried pressing on the gas pedal, it wouldn't budge and felt very stiff. I'm thankful this happened at a smaller intersection on a Sunday evening because my car wouldn't start back up and was stuck in the dead center of this intersection. Cars going east and south all had to drive around me. This put my safety at risk because I had to hop out of my car and redirect people around it until a kind passerby pulled over to help push my car to the right-side turning lane. I was standing in the middle of an intersection on a road with a 35-40 mph speed limit. After pushing the car to the curb and calling a few towing places (maybe 20 minutes later), I tried starting the car again, and it started with no issues whatsoever. I drove it the rest of the way back (for 3 minutes) with no problems, and I made another three 20-25 minute drives on it today. Nothing sounds wrong with the car; it's running with no issues. I would take my car to the dealership for a diagnostic, but I can't afford to right now. I will put my battery on a tender and use a multimeter to check the voltage within the next few days. Regular maintenance has been kept, and the car has never had this happen prior. I've never received the "engine stopped steering power low" message prior to this incident. The car is available for inspection upon request.

I have a 20202 Rav4 hybrid and the engine short block has malfunctioned due to no error on my part, in my research there was a recall for this exactly this issues in other cars of this year/make/model - although my vehicle initially did not qualify for this I believe that this in fact related and that Toyota should be responsible for the repair or replacement of the engine. The car is currently with a Toyota dealership service center, lake city Toyota in seattle, wa but they have not been helpful. They have given me vague answers and have sent the engine offsite to a machine shop and keep requesting that I pour additional money into fixing an engine that clearly had a manufacturer defect. My car has always been serviced at Toyota dealerships, as suggested by Toyota. My car has never had previous issues until the engine light came on one day, I checked the coolant and it was empty - first replaced the fluid, let it sit overnight, then drove it around the block to circulate the coolant - when the reservoir emptied again I immediately made an appointment to take it in. The dealership has not given me any paper invoices or written confirmation/notice of what is happening aside form continuing to ask me to pay more money to fix an engine that is clearly related to the national recall issued.

Shortly after having vehicle serviced at Toyota the engine maintenance light came on. Imagine my surprise at learning that many other Rav4 owners have the same exact issue right around the 65,000 mile mark.
