This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Car lunges forward 10ft or so intermittently when braking is applied. This is very dangerous given situations. Toyota dealer is given new car models under 36k miles a free fix, but they would charge high mileage cars a lot of money. I wish NHTSA demand Toyota provide free fix for this issue.
When the vehicle hits a bump or you are turning while using the brakes, it feels like the brakes cut out for a moment and the vehicle surges further forward faster than you expect it to.
During braking, when almost stopped, the vehicle lunges forward so I have to press harder on the brake so I don-??t hit the car in front of me. No potholes or irregularities in the pavement. It-??s just a loss of brakes. It-??s happened several times now.
When braking vehicle feels like it is being bumped from behind. Dealership says it is the vehicle switching from regenerative braking to normal breaking but it causes the car to lunge forward. It feels like the vehicle is going to lunge into oncoming traffic. I have to slam on the brakes to stop it. It-??s very unsettling.
when approaching a red light (or any attempt to slow down) and I press on the brakes, some times the car starts to de-accelerate normally, and then a second or two later, de-acceleration stops for a brief moment. Eventually, the breaking system makes the car stop, but the distance it runs until total stop has definitely been compromised.... plus, the scare factor is concerning. This happens randomly.

While braking car will lunge forward regardless of speed. It happens several times a week since purchase of vehicle. I had a few near miss accidents where I almost collided with a vehicle in front of me. There is no warning lamp indicator for this event. Investigating on the internet gave me insight that this is a common problem not being addressed by Toyota.
When braking vehicle will accelerate for a brief 1-2 seconds then go back to braking, causing sudden jolts forward and increase distances needed to stop the vehicle, this was only noticed recently in the last 6 months and are at 20K miles as of July 2024, but is becoming more and more frequent, this happened twice on 7/8/2024
While slowing down to about 10mph to turn, brakes suddenly disengage and the car lurches forward. This happens every day, sometimes multiple times a day.
Problem with regenerative braking while braking. When coming to a stop the regenerative braking is engaged and sometimes the regenerative braking disengages before a complete stop causing a change in required braking force to stop the vehicle. This can cause a sudden jerk of the vehicle when having to press the brakes harder which can cause a whiplash movement.
I turned right to park behind another car on the driveway and my car suddenly accelerated hitting the car in front. The collision was strong enough that the car that was hit then hit a barrier at the home.
When going down hill and needing to brake at a stop sign the brakes feel like they release for a second causing me to move further forward than expected. When I press further on the brake peddle they seem to engage again. Concerning since I'm going into a stop sign at the bottom of hill. The sensation is as if I'm slipping on ice and loosing the ability to brake before they engage again. I have to drive this everyday and has happened several times but not able to replicate it and the dealer has not been able to reproduce it, therefore nothing is wrong according to them. No warning lights appear. The brakes have not been inspected since the dealer feels there is nothing wrong. If I'm ever not able to get the brakes to re-engage then I will run the stop sign and off the embankment on the other side.
Approximately 4-5 times it has felt like the brakes have slipped or let go for a very brief moment. I have either been braking over bumps, or braking going downhill. It is a slipping feeling, like is felt when briefly sliding on a patch of ice, or hydroplaning. It occurs for only a second or two. It has happened when conditions were dry.
UNKNOWN. Randomly, while lightly braking, the vehicle will lunge forward. Does not always happen and unable to recreate it but has almost caused a few accidents. Van lunges forward for a second or so and then the brakes will re-catch or work again and the vehicle slows again. Scary. Have gone to toyota dealership but they insist nothing is wrong and they haven't heard of this issue. Forums with other Sienna hybrid owners state the same issue. Unsafe. Has happened multiple times, happened twice this last week.
While driving slowly into a parking slot, the brakes released and the vehicle surged over a parking block and into a sign. On a couple of time previously, I have encountered similar situations but never when parking at slow speed.
