I own a Toyota Sienna and got a notification from Carfax that there was a recall on the car. I looked up the recall on Toyota's website and it confirmed there was a recall. I called my dealer--Jim Coleman Bethesda--and asked them if it was safe to drive, explaining that we have a [XXX] and [XXX] old and use both rows of seats. They told me it was "perfectly safe to drive," including in those two rows. Toyota has, however, separately stated that drivers should not use the second row of seats. Our dealer has now informed us that we can have a loaner, so this isn't an issue for us. But I'm alarmed that the dealership gave this inaccurate information despite my repeatedly pressing them that I wa

My name is [XXX]. I am an automotive Technician and I have completed hybrid vehicle system training. I have a certification of completion for the hybrid training.I work for XXX [XXX] maintaining and servicing a fleet of vehicles. I am contacting NHTSA regarding a safety concern with a 2024 Toyota Sienna Hybrid that I inspected. The vehicle has an intermittent braking concern. The driver reported that while braking, the vehicle sometimes seemed to move or jump forward instead of responding normally to the brake pedal. On one occasion, the driver reported that the brakes did not respond as expected and the vehicle nearly proceeded through a red light. I inspected and road tested the vehicle, b

Three (3) separate systems failed. 1. Upon seeing cars ahead of us slowing down, my husband pressed the breaks to slow down to avoid collision. When he pressed on the breaks, instead of slowing down or stopping the vehicle, the brakes failed to engage, and caused a surge that compelled the vehicle to lurch forward. The lurch propelled our vehicle into collision with another vehicle. 2. Also, the forward collision warning system failed to alert or engage the breaks. Our vehicle was stopped by the impact of hitting the other vehicle, not by its own breaks. 3. The automatic breaking system also failed to engage at all prior to impact.

I have never been in an accident in my 31 years of driving. However, I am worried that this van is going to cause me to be hit. Several times I have pulled out to make a left or right turn and my gas pedal does NOTHING. I can push it clear to the floor and NOTHING!!! Cars end up slamming on their brakes and honking at me but there's nothing I can do. This is EXTREMELY scary and a HUGE HUGE HUGE manufacturing flaw. There needs to be a recall for this to be fixed before people are injured.
