2021 Toyota RAV4

I have had several intermittent occasions over the past 3-4 years where the brakes do not stop the vehicle when depressed. I can feel something through the brakes pedal, but cannot explain what it is. So far, I have been able to avoid any accidents, but the infrequency makes it impossible to determine if it is going to happen.

The contact owns a 2021 Toyota Rav4. The contact stated that while driving approximately 50 MPH, the transmission failed to function properly. The contact stated that there was an abnormal sound coming from the transmission while shifting from fourth to fifth gear. The transmission was whining while accelerating and decelerating. The contact was concerned about metal flakes inside the engine. The contact called a service center to report the failure. The failure mileage was approximately 89,000.

While changing lanes in my 2021 Toyota RAV4 with my turn signal activated, the Lane Departure Alert / Lane Tracing Assist system applied an unexpected steering input that pulled my vehicle directly into a Jersey barrier, resulting in physical contact with the barrier. I was intentionally and safely moving into the adjacent lane when the system intervened abruptly and steered my vehicle toward the barrier. My speed was approximately 55 - 60 mph. The weather was rainy off and on but not raining at the time. The road surface was damp. The lane markings were clear and no dashboard warnings appeared prior to the steering event. I had my blinker on and was actively changing lanes. The lane‑assist system should not have intervened during a deliberate lane change, yet it applied a strong steering correction that overpowered my input. I attempted to counter‑steer, but the system’s force caused my vehicle to strike the barrier. My vehicle made contact with the Jersey barrier, causing damage to the driver’s side of my vehicle. The unexpected steering input created a sudden loss of control and a dangerous situation that could have resulted in a more severe crash. I am aware of other 2021 RAV4 owners reporting similar unintended steering behavior with lane‑assist systems, including steering toward barriers or roadside objects. This appears to be a recurring safety defect involving the vehicle’s lane‑keeping functionality. A lane‑assist system overriding a driver‑initiated lane change, especially with the turn signal activated, and steering the vehicle into a fixed object presents a serious risk of injury or death.

I am reporting a serious safety concern involving the sunroof glass on my 2021 Toyota RAV4 Hybrid Limited AWD. On July 3, 2026, at approximately 37,350 miles, I was driving the vehicle when the entire sunroof glass suddenly and catastrophically shattered. There was no traffic around me, there was no debris in the roadway, I was not traveling under an overpass, and I am not aware of any impact or other event that could have caused the glass to break. The failure was completely unexpected. I heard a very, very loud sound, similar to a gunshot. Immediately afterward, the entire sunroof glass had shattered into small granules. A very small piece of shattered glass also flew off the vehicle. I was able to quickly close the interior sunroof visor, which fortunately prevented the majority of the shattered glass from falling into the passenger compartment and prevented injury. There was nevertheless some glass that fell into the roof liner. I immediately contacted my insurance company and the car was towed to my Toyota dealership. The sunroof was replaced with a Toyota original part and the replacement was paid by my insurance company. This incident created a significant safety hazard because the sunroof glass failed suddenly and violently while the vehicle was being driven. The extremely loud explosion-like sound and the sudden loss of the sunroof glass could cause a driver to lose control of the vehicle or could result in glass striking occupants. In this instance, I was fortunate that the visor was closed quickly and that there was no surrounding traffic. I believe NHTSA should investigate whether there is a defect or other safety-related problem with the sunroof glass or its installation in this vehicle, particularly if similar spontaneous breakage incidents have occurred in other Toyota RAV4 vehicles. I am reporting this incident because the glass appeared to fail spontaneously, without an apparent collision, road debris, overpass, or other external impact.
