2019 Toyota RAV4

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.

Driver was in the process of parking. While driver had foot on brake and about to put vehicle in park, vehicle suddenly lurched forward uncontrollably, jumped the curb, ran over thick bushes, and ran into the front window of a store. as soon as vehicle stopped, driver placed the vehicle in park. None of the safety features prevented this.

Received multiple malfunction alerts. BSM & RCTW. Other safety features also inop. Dealership told me it was due to non-factory installed Cross Bars, faulty gasket allowed water into vehicle and flowed down onto the Engine Control Module. There was no way the amount of water said to have been in vehicle could have come from that 1 gasket, over 1" above roof. After $825+ and removal of cross bars water still leaking into car. Concerned issue will re-occur making safety features worthless, as well as damage side air-bags. These issues would all need to be corrected via out-of-pocket expense. Believe the issue is design flaw from Toyota.

Driving on 35MPH limit road. Vehicle began to stutter. Vehicle began to communicate warning lights - "PKSB Malfunction" and "Hybrid System Malfunction" and "Check Engine" and alerted to visit dealer. After stopping at red-light, received warning to pull over and stop driving. Vehicle could not exceed ~10mph no matter how much accelerator was depressed and received warning that vehicle had ~2.5 miles until it would cease being able to be driven. For rest of trip to home (approximately 2 miles), vehicle would alternate between 10mph limited state and returning to full acceleration which led to very unsafe driving conditions and abrupt changes in speed. Reached home and parked in drive way. After a few hours, returned to vehicle to take to dealer for service. All 3 error messages remained but no further limitation to 10mph or abrupt speed changes. Dropped off for service at dealership. Dealer notes: "Hybrid system malfunction, check engine light - SCAN FOR CODES, FOUND U010087 LOSS OF COMMUNICATION BETWEEN PCW AND ECM / CLEAR CODES, UPDATE SYSTEM, OPERATING AS DESIGNED." Upon receipt from dealer, no further issues and drove home safely. Vehicle is a 2019 Toyota RAV4 Hybrid Limited, bought new in Jan. 2020. Approximately 23000 miles, no previous issues. Has been maintained regularly (oil changes, etc. via Toyota Care).
