2022 Toyota Redundant Sienna

While driving at about 40mph on a city street I complete lost steering, brakes and vehicle control. I suddenly started severely swerving/ spinning. I suddenly had no control over the vehicle. The vehicle threw a bunch of codes at once including: anti-lock brakes malfunction, pre-collision system malfunction, secondary collision brake system malfunction, braking power low, parking brake malfunction. I tried to turn off and restart the car and it did not reset any codes. I have brand new tires on the vehicle and just had an oil change and check up two weeks ago. There was no reason for this to happen other than a complete and sudden safety failure of apparently multiple systems. Vehicle is currently being inspected by local Toyota dealer.

For over a year now, I have been experiencing a random issue in my van with the brake system. It feels like a slippage when I hit the brakes to slow down and it will randomly feels like something slips and just give gives out and gets loose and like you are free falling until the brakes grab and actually stop. I have had it in the dealership twice to fix this issue. Last year they reprogrammed the brake actuator assembly control module, and it worked for a while, but then once again after several months, it started again and the second time I took it in they drove it around to try to get it to mimic the problem, but was not able to so Couldn’t do anything about it and just said to watch it and see if it became more frequent. They also said that once you have the actuator reset the computer shows updated and can’t redo it.The problem with this issue is that it is random and sometimes it’s less and sometimes more and I can’t give specific dates because of the randomness of the problem. I have never not had it to stop, but I am including my two invoices from Toyota of Richardson where I’ve had it seen as well as the research that I have looked up in different forums where other people are describing the very exact same problem with their vehicles. [XXX] . It is scary because you don’t know if it’s going to stop or not but so far it has. [XXX] . There is an issue, but don’t know how to permanently solve it or know for sure what it is. The forum does explain some different things because of the vehicle being hybrid, but who knows whether that’s it. Please look into this and advise because I do not wanna wait until this is a problem and I have a wreck because I am not able to have my brakes work Correctly. P.s. The dates entered for the incident below is not accurate due to obviously the issue being random and ongoing not just one time.Thanks. [XXX] .

Brakes release briefly when slowing to a stop. While slowing to a stop with steady pressure on the brake pedal, the braking action will momentarily give out, resulting in the vehicle lurching forward beyond the anticipated stopping/slowing distance before the braking action re-engages. This has resulted in near collisions with cars, bikes, and pedestrians as the vehicle suddenly stops slowing without warning and unexpectedly increases stopping distance. The problem is intermittent and difficult to reproduce, but has occurred repeatedly over at least 6 months of ownership. No warning lamps, error messages, or other related symptoms from the vehicle either before or after occurrences of the problem. Has been taken to the dealership for an update to the vehicle but it didn’t fix it. There are multiple reports online and multiple lawyers talking about this.

When braking and coming to almost a complete stop, the vehicle will randomly lurch forward. This situation has caused me to run stop signs and almost hit pedestrians on crosswalks. This failure has been independently observed by myself, wife and mother. The vehicle did not display and warnings prior to the failure. The vehicle has not yet been inspected or reproduced by a third party.

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? CONSISTENT DECELERATION DURING BRAKING How was your safety or the safety of others put at risk? CONSISTENT DECELERATION CEASES FOR PERIOD OF 1-2 SECONDS Has the problem been reproduced or confirmed by a dealer or independent service center? NOT YET Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO, ALTHOUGH OTHER OWNERS HAVE EXPERIENCED THE SAME
