When decelerating, particularly on hills or into corners, there is an intermittent surge that occurs after the brake pedal has been depressed. It feels as though there is a release of the braking action, this is unsettling as if you are starting to approach a vehicle or pedestrian, this sudden "delay" of braking could result in contact with other objects. We have changed our driving behavior as a result of this. We reported this behavior at 5000 miles and there was not a solution until last year. We were not notified of this, and our vehicle is now out of warranty. Toyota has released as of last year a TSB related to programming and we are going to pay out of pocket $300 this week to get that TSB applied. This doesn't seem fair to consumers. You can see this is not an isolated problem here: [XXX] , a 2025 and 2024. In both of those vehicles, this behavior is not present.

I am writing to formally raise a serious and unresolved safety issue with my 2022 Toyota Sienna. The braking system on the vehicle behaves abnormally: when the brake pedal is pressed, the van does not stop immediately. In fact, it momentarily accelerates before decelerating, an extremely dangerous malfunction that has nearly led to multiple accidents. I have brought this issue to your attention several times: • In 2022, I contacted O'Regan's Toyota, the Halifax dealership, which has been unable to diagnose or repair the issue to date after several visits. • In 2023, I contacted Toyota Canada directly. I was referred to the dealership in Halifax. • The Halifax dealership has been unable to diagnose or repair the issue to date. • Despite the unresolved nature of this problem, the dealership has recently asked to charge me diagnostic fees for the same issue, one that remains unsolved and is clearly a manufacturer-level safety defect. This is not a minor inconvenience; it is a fundamental failure of the braking system and presents a critical safety hazard. The fact that this issue persists without a resolution, and that I am being asked to pay diagnostic fees for a problem that Toyota has not addressed, is unacceptable.

When braking there is a lunge forward sensation that causes the van to propel forward a little. The happens intermittently and can cause scares especially when driving with children. A T-SB-0047-24 was applied and still experiencing the same issue as it did not solve the issue.

During braking, I occasionally get the unexpected feeling that the car isn't stopping. It presents a risk to safety. The problem remained even after I paid for the TSB. There is no pattern to it.

When braking, the vehicle "releases" and lurches forward at a faster rate, but then catches again and continues to brake as it was before.

When braking, the vehicle "releases" and lurches forward at a faster rate, but then catches again and continues to brake as it was before. It does not flash or light up on the dash with any issues when this happens. We have tried to find how to specifically recreate this issue to show to the dealership, but it just happens randomly anywhere from 2-12 times a day. This is especially terrifying coming down steep hills or taking quick offramp with stopped traffic in front of you. It began about a year and a half ago and used to take place once every few weeks, it is now happening daily, with increased "release" strength and time. It is still only about 1-2 seconds of released brake pressure, but again is terrifying when behind the wheel and expecting your vehicle to continue to brake as normal while foot is on the pedal. The brake pedal does not depress further or move from its position when braking. The car is acting and performing just as it should be 'normally', except that the brakes give way for 1-2 seconds.

Unexpected sudden acceleration (when braking) as I was slowing down from exiting a highway, just as I was approaching full stop, it felt like the regenerative braking stopped grabbing momentarily and I violently lurched forward for what seemed like a feet or two. I thought it was a fluke back then and thought nothing of it. It just happened again today as I approached a stop sign - again as I neared complete stop with brake depressed it felt like the brake stopped working for a second and the car again lurched forward violently as if I had lost control for what seemed like a foot. Would have hit the car in front of me if there was one.

Brakes randomly feel like they are slipping when I go to stop, could be a flat surface, but almost always if I am coming to a stop on a bumpy surface.

seat retractor failure- white plastic part off and visible , seat is making popping noise when seat is being adjusted. Noticed this when i picked up from dealer after oil change. I feel this is a driving safety concern. Larry H Miller American Toyota (Albuquerque, NM) service manager states it's safe to drive, however I feel this is a huge safety concern. The seat was in working order did not have this issue during drop off of service. However I believe this is a failure on Toyota engineering. I would like some guidance on how to get this repaired as they want me to pay $2,000.
