While driving in the mountains on a hot day, the car suddenly reported numerous faults, including check engine, parking brake malfunction, pre-collision system malfunction, AWD system malfunction, and secondary collision brake system malfunction. The car lost power and forced us to pull over on the side of a dangerous mountain highway. We powered-off the car for a few minutes and started it again and were able to proceed to our nearby remote mountain destination without another loss of power, but the faults remained. The next day we were able to get the car to a nearby NAPA store to read the check engine codes, which there were only 2 of the "P0087" code. I had them clear the fault codes in order to be able to safely drive the car (~120 miles) back home. Some quick research shows a known issue and TSB for that in our exact high-altitude and high-temperature situation - Toyota T-SB-0058-22, related to a known design flaw with the ECM and fuel suction tube. Luckily, it did not throw the errors again during our drive home. I made an appointment at our local AutoNation Toyota Arapahoe for the following week. I detailed the issue and provided pictures of the errors - including the code reader display. The dealer claimed to not find any issues and refused to address/execute the TSB, stating that the code must be active and present in order for them to fix it and that my pictures were not sufficient proof. I explained that it was an unacceptable safety risk to have left the car in that state and that the issue is known to only occur in certain conditions (e.g. high-altitude, high-temperature mountain driving). Issue remains un-addressed, which is highly unacceptable and poses a serious on-going safety risk.

Rav4 2019 - We lost engine power while driving on the highway at 75 mph. We were in the #2 lane and were fortunate to be able to coast to the side of the road. Quite scary as there were semi trucks behind us.We had been driving for approximately 3.5 hours on the highway at 70-75 MPH. The outside temperature registering on our vehicle began at 110 and continued to increase on up to 118 degrees at the time of the incident. When we lost engine power, the following errors began flashing on the dashboard: PKSB Malfunction, Pre Collision System Malfunction, Secondary Collision Brake System Malfunction. We cleaned the sensors, turned the car off for 5 minutes and then turned it back on. Same warnings appeared. Got towed to the Toyota dealership. Next day all malfunction warnings gone. Car was behaving normally. Toyota service team was unable to reproduce the problem. They inspected the electrical, battery, sensors, etc. but could not find anything. Ultimately the service lead stated that the intense heat could have caused sensor malfunction. Scary!! We fortunate!

Infotainment Center turns on and off, and will not work. Because the screen turns on and off, the camera for back up intermittently works. May 2025 i took it to Karl Malone Toyota in Sandy Utah. They said to buy a 3rd party, after investigation I confirmed that no display has the options to reset maintenance, change clock on the dashboard, and communicate with the car. Yes radio, navigation, carplay, etc work with a 3rd party system, but the functions that talk with the car do not work on any 3rd party system.

My check engine light is on due to O2 sensor being dirty. While this light is on some features in the car are disabled like cruise control. It might also be that the ABS braking system is turned off! I am not sure but once when the car in front of me abruptly stopped I was surprised my emergency braking did not kick in.

A Hybrid System Malfunction warning appeared about 1 week ago. The car was taken to the Toyota dealer who said that the car was safe to drive and that they would need to order a part and it will probably be weeks before they get it because so many other cars have the same problem. Three days later the car will not start with several errors including Brake Power low, PKSB Malfunction, and Precolllision System Malfunction. Toyota is not providing any coverage for any of our repair, car rental or now the need to tow the car.

My 2019 TOYOTA RAV4 ADVENTURE is groaning, especially when accelerating or decelerating, particularly with the AWD system engaged. Plus, there no or slow forward collision warning. Toyota seems to ignore these issues related to the Adventure RAv4 of 2019 and 2020. Thanks

Initially thought a seal on the windshield was faulty, so contacted the business who replaced the windshield. Business owner came to owner’s house Mon, Nov 4, 2024. He did a thorough inspection of all areas where water was identified by owner (dash, under the dash, on the driver side floor) and confirmed it was not the windshield. He then inspected the roof rack and determined the roof rack was defective and leaking water from the ceiling of the vehicle, down into the dash, and ultimately onto the floor. He recommended contacting Toyota because this was a known issue. By 12pm on Mon, Nov 4, 2024 owner contacted Toyota alerting them to the issue. An appointment was made to bring the vehicle in for inspection on Mon, Nov 11, 2024. Owners do not have a garage or carport, so a canopy was pitched over the car in an effort to prevent any further water damage and moisture absorbing canisters were placed in the car. The vehicle was not driven in the rain during the period after first noticing the leak and bringing it in to the dealership. Evidence of Electrical Damage: On Friday, November 1, 2024 the driver side seat became extremely hot, to the point of needing to pull over and turn the car off. The seat heater was not turned on at any point during this time. On Saturday, Nov 9, 2024 and Nov 11, 2024 while driving on the highway, the car (normally driven in Eco Mode) unexpectedly switched into Mud&Sand mode and all safety features switched off. Owner was unable to manually override this occurrence. The “Normal” button did not work. After a few minutes, the vehicle switched into the default setting and owner was able to put it back into Eco Mode. On Nov 11, 2024 owner brought vehicle into Toyota for diagnostics. Owner requested that the electrical components also be inspected and was told it was not covered under the Customer Support Program.
