2024 Toyota Sienna Hybrid

While driving at very low speed on a residential street, my wife was braking when our Sienna struck an unoccupied parked Toyota Tacoma with the right front corner. She believes she was braking and the van did not slow as expected. The pre-collision system did not brake or warn. We have repeatedly noticed the van surge or lurch forward while braking at low speed, such as when pulling out of our driveway. We are aware of Toyota service bulletin T-SB-0047-24 on brake surge in 2021-2024 Sienna hybrids. Damage includes the right front structure, hood, fender and headlamp, with repairs estimated at about $19,900. The vehicle is currently at a body shop (Haws Auto Body, Lafayette, CA).

I have been having issues with my 2024 Sienna XSE since about 6 months after getting it. The break surge, jump, lurch, slip, etc. so many different names people call it, is the issue and it needs a permanent fix! I had the ‘software update’ done from the bulletin that is out for this issue about a year ago and it finally went away…but only for about 3 months. Ever since then, it has gotten so much worse with time now. I wish I never got the update. It is happening much more frequently, like twice a week! It doesn’t matter about road type, turns, hills, etc. anymore as long as I’m breaking it happens. The slip is getting longer and not catching as quickly and I nearly hit a car that was stopped at a light yesterday because of the re-acceleration, and I was breaking with plenty of time.

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 was concerned that I had seen different things online. The dealership is who customers will call if they have safety questions and they should not be telling owners that it is safe to drive where Toyota has issued different guidance.

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, but I was not able to duplicate the problem at that time. I also performed a full system scan and found DTC P162B87 in the Hybrid Control system. I contacted a Toyota dealership regarding the concern and also asked about Toyota T-SB-0047-24, which appears to relate to a transition between regenerative and hydraulic braking on certain Sienna Hybrids. The dealership told me that the bulletin does not apply to this vehicle’s VIN. Because this is an intermittent braking concern that could potentially affect vehicle safety, I would like to report it to NHTSA and find out whether there are other similar complaints or any additional information available regarding this issue.

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.

Flash reprogramming allows the Electronic Control Unit (ECU) software to be updated without replacing the ECU. Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Global Techstream+ (GTS+) ECU flash reprogramming procedures and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard+ (CUW+). To ensure the correct ECU software is installed, ECUs will require a Security Signature before the ECU will initialize the flash reprogramming sequence. This bulletin also details the process for acquiring a Security Signature from TIS during the GTS+ ECU flash reprogramming process.
