2019 Toyota RAV4: adaptive cruise control problems

Filed Oct 10, 2025 · Driver assistance · FL

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.

While driving at interstate speed and cruise control set, the cruise control stopped working and Cruise Control Malfunction errors, as well as Hybrid System Malfunction errors appeared. With other cars driving so closely behind me, the quick deceleration caught me off-guard and could have easily been hit from behind. I took the car to Toyota Dealership and appears there's already a known issue for a corroded traction cable and since not under warranty (due to mileage >120,000 miles) will cost $4668 to fix. Why is this not a recall if the problem is known?

I was stopped at a red light. When the light turned green and I pressed the gas, the engine sputtered and almost shut off. Just before I came to a stop, the engine revved up and the vehicle accelerated. The uneven acceleration is concerning. I recently replaced the gas cap and serviced the fuel system, which leads me to believe there is a defect with the engine. Later in the day, the check engine light went on and AWD system, cruise control, and lane assist were disabled.

SUV showed on the display that there was a Hybrid System Malfunction. SUV is in a Toyota dealership shop in Aberdeen, WA. I called the shop immediately when the notification came up. Was advised that it was OK to drive until check engine light came on, which it didn't. I only drove to work amd back after the notification and call to shop. The cruise control would turn off and I'd be notified on the screen. Again was told ok to drive until check engine light came on. Approx a week after calling shop, SUV would not start before going to work. Had to be towed to shop. Potential safety issue if this happened while driving on highway or while in a rural/wooded/off main road area with no cell phone service. I was told my the shop that another SUV had recently had the same issue. Shop says that the wiring harness is exposed to the elements as built by Toyota. Has not been inspected by anyone but the Toyota dealership service dept. No warning ahead of time, just a notification while driving that there was a Hybrid System Malfunction amd then a Cruise Control Malfunction.

This vehicle has continued to have issues. The most recent and dangerous issue is the electrical problems due to water leakage. Water getting into the vehicle's interior can be hazardous with all the solenoids, modules, and wires. The roof rack leaking is a common issue for these vehicles. It does not become an issue until they have been exposed to rainy environments or washed. The water in our vehicle leaked down the driver-side A-pillar, behind the steering wheel, and into the floorboard. This caused a shortage in wiring for the mud/sand terrain modes and the safety systems for the vehicle. This would happen at random times, including down the freeway at 70mph. The adaptive cruise control would shut off and emergency braking would be defective if needed. The water does flow across the airbag in the A-pillar which could cause a more serious issue. Now, there is a possibility of the airbag not deploying in the case of a collision. The racks leaking is something Toyota should be recalling or publishing a TSB.

Engine stalled on a highway going 65 mph in cruise control. I had 1/4 full fuel tank. just before the engine stopped working I read information on my dashboard I have to stop the car in .5 miles, than .3 miles and engine stalled within seconds. I was able to pull over with dead engine. I shut down the car using key (I have a mechanical key for ignition) and car started with a message 'hybrid system malfunction. output power reduced . visit your dealer." I visited local mechanic who read the codes and instructed its a faulty fuel pump. I filled the car with more gas and drove couple of miles with reduced power. I left the car for 36 hours and it started to run ok by itself. dealer replaced fuel pump and now it works fine. The day of incident I was able to smell gas around engine bay before incident. I was able to smell strong gas smell after incident after I filled more gas in the vehicle most likely from engine bay fresh air intake. My assumption is this is due to bad fuel/air ratio and the result was unburned fuel. The week before the incident engine felt it kicked in roughly on its start up (my car is a hybrid). I had a fuel pump recall performed 4 months before but the fuel pump failed based on codes p319300 p008700 p107a2a . dealer replaced fuel pump (2nd time) and car works well and much smoother than before.

Cruise control and other safety issues randomly go off line. When driving cruise control turn off, as do the electronics. Further, the automatic bright lights are random to the point I have to disable the system. I have pics and video, cannot change format, don't know how.

Driving the vehicle at 65 miles on a freeway I drive daily. While having the cruise control active the vehicle suddenly and drastically reduced the speed to almost 0 when the vehicle got closed to another vehicle on the right side lane making a right turn. The vehicle turning was not on my lane in front of me it was already in a separate lane making the turn. The vehicle has done this 5 times in the year I have owned it.

Vehicle does not function as advertised, ECM appears to change shifting, hybrid, and gasoline usage at lower temps. Pre-collision system malfunctions with any visibility reduction, causing the vehicle to suddenly brake at highway speeds or to not brake at all with radar cruise active. Also have same issue as others with not being able to fill tank more than 10 gallons of 14. Mileage is as low as 24 mpg for a whole tank, driving very conservatively.

The 2 inch multifunction display on the 2019 toyota ravv4 is creating a dangerous condition. The gee-whiz fuel economy data is predominantly displayed in the center of the screen while the important and often used cruise control speed setting is in a barely readable sized font. Other more useful data is also displayed in very small font. Toyota should be required to reprogram and update the display.
