While applying the brake at the stop light. (25 to30 mile speed limit zone) The Toyota hybrid sienna start to accelerate for split 5 or more seconds. I have to apply the brake harder even though I was already applying the brake to slow down because the light was red and the are several cars in front of me. For the first time I was scared thinking about rear ending some one in front of me or the Toyota Lexus incident where it accelerated and everyone died flashing through my mind. It was not a good feeling.

Stepping on brakes - Car slows then accelerates a few seconds and lunges forward a couple of feet. Extreme safety issue. This occurred yesterday with my sister in the car and we almost rear ended the vehicle stopped in front of us. I have complained to the Cumberland Toyota dealership in the past and was told if they cant recreate the issue and it doesn't happen all the time there is no way to fix the issue. Yesterday I was almost in an accident because of this faulty design/anomaly associated with my car. This lunging forward is not suppose to happen and I want it fixed Toyota needs to come up with a resolution before it kills me. I have purchased this vehicle new 2024 and it has been happening since purchase - NOW its really bad

While driving on highway, on 3/11/26, car powered down. I had to coast to side of highway. I was able to turn vehicle on after several minutes, but SEVERAL system malfunction error messages (hybrid, accelerator, pre-collision, tpms, airbag, engine…) appeared. The vehicle would not accelerate beyond 10mph. Once I moved it to a safe location, I had the vehicle towed to the dealership. The dealership technician was able to replicate the issue during test drive. The technician apparently had the vehicle towed back to the dealership last night. The car has had other related issues since June 2024 when I bought it. The TPMS system, the accelerator system, and the airbag system have all malfunctioned independently. The accelerator system malfunctioned in Jan. I had to pay for a replacement fuse despite the warranty. The vehicle is modified with Braunability equipment for wheelchair access. These modifications are approved by Toyota and were completed by MobilityWorks. Aside from the vehicle itself being unsafe to drive, the passenger sliding door has had numerous problems. On 3/07/26, the door mysteriously slammed shut after opening and would not open again. These are all dangerous situations that could have resulted in fatal accidents.

Dear Sir/Madam, I am writing to formally raise a complaint regarding a serious and ongoing issue with my 2024 Toyota Sienna XLE AWD, purchased in April 2024 in Illinois. From the very first day, the trunk door has not functioned properly — often failing to close, randomly opening, or requiring manual force to shut. Despite repeated service visits across multiple states (IL, SC, NC) and investing considerable time, fuel, and lost income as a contractor, this issue persisted for over 18 months, creating safety concerns and inconvenience for me and my family. Key Issues: Trunk door opens on its own – even while reversing, creating serious safety risks. Malfunctioning power close mechanism, requiring manual closure frequently. Unreliable performance: door would close, then immediately re-open. Visited Toyota service centers at least 6 times across 3 states. Each visit took 2–3 hours, costing me work hours as a contractor. Customer service experience has been poor, especially with manager Patte, who: Failed to schedule proper service appointments. Directed me without coordination. Refused to escalate my request or connect me to her manager. Dismissed my request for compensation by saying, “It’s your issue.” Please help me on this issue. Thanks in advance.

The interior dash lights, when turned up to max brightness, take several seconds to read when making adjustments to the climate controls. These dim controls pause a hazard as it takes your attention away from driving. The dealer told me that they could not make them brighter. The issue is at night and day times.
