2018 Toyota RAV4: lane keeping assist jerks the wheel

Filed Dec 18, 2020 · Driver assistance · 75 miles · CA

The lane departure warning buzzer's warning cannot be heard on the road with the radio on low volume or with a radio off but driving above 75mph due to the road noise. Multiple complaints to different dealers resulted in comments that the buzzer works as designed. Calls to toyota's "brand engagement advocate" resulted in advice to go to a dealer. They have no authority to instruct the dealer to replace the buzzer. I understand that ldw is mandatory for 5 stars safety rating, but I cannot find the specification for this safety feature.

Lane departure warning, seat belt warning, pedestrian warning and other auditory safety feature warnings are not adjustable and therefore may be inadequate in providing the intended safety function. The manufacturer should retrofit a control that makes it possible to adjust the safety function to the individual needs of the driver.

The lane departure warning system works intermittently at night on a wet roadway. The vehicle was on a four lane road with two lanes in each direction. Speed was around 45mph. Lane departure warning works above approximately 32mph. The system would not recognize the white shoulder line on the right hand side of the vehicle or the dotted white line on the left hand side of the lane. This was the second time this had happened to me. The other time was approximately a month ago.

If you drift away from another vehicle or obstacle (pedestrian, bicycle, etc) that is also drifting into your lane, the lda system (lane departure assist, which is touted as a safety feature) will pull you back towards the obstacle you are trying to avoid. Clearly this is a safety hazard and should be removed as a "feature" from the vehicle. Toyota should also stop calling this a safety feature. Secondly, the radar assisted cruise control will start braking if it sees the vehicle in front is slowing down. However, if the system then thinks an accident is imminent, the crash warning shows up and the cruise controlled braking is then disabled causing the vehicle to stop the braking process, and thereby causing a safety hazard since the car will now coast into the obstacle. Again, this is a surprising and terrible implementation of this system that should be removed or fixed.

Vehicle's lda (lane departure alert) could not be heard and no volume adjust. Dealer won't do anything about it claiming there is no standard loudness required. Yet, the lda is part of toyota safety sense and marketed as alert for safe driving assist. My vehicle is 2 weeks old and missed the warning twice already. False advertising by toyota as safety alert when it could not be heard. Dangerous to depend on it.01/29
