2024 TOYOTA SIENNA Unknown Or Other Problems

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.

On various occasions while braking there is a sudden acceleration that occurs. Generally lasting less than 5 seconds. More noticeable going down hills but has occurred on standard driving. Date provided is most recent occurrence after service from Marietta Toyota for recall and 25k service.

On June 5 th the vehicle was going approximately 50 miles per hour in the middle lane. I placed on the brakes suddenly and car lost power and stalled out. Unable to restart vehicle for 5-10 minutes on the freeway. Significant safety concern due to vehicles sudden stall out in mid the highway traffic and unable to restart car. Almost hit from behind as well as others that followed from behind. On Jun 7th vehicle was taken to the Toyota dealership and car checked by special mechanic and reported that they were unable to reproduce the stalling or issues with restarting the vehicle.Dealership feels there is nothing wrong with vehicle. There was 2 warning messages on vehicle when stalled suddenly 1-Charge 2- Fluid

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.

Drove the car in rain and undercover guard broken down, Toyota is using a flimsy material to cover the undercover and not reliable, long run can cause engine damage and other broken components

2024 - Toyota Sienna Woodland Edition - Purchased Oct 3, 2024. When you park the vehicle and put the vehicle in Park, the vehicle thinks that it is park. However, when you come back and start the vehicle, the vehicle again things it is in park, HOWEVER, you are not able to open the power side doors or the rear tailgate using the overhead open button, or using the remote. The vehicle thinks that it is in gear.

When I open the Entertainment in my seinna car it's completely blocking the rearview mirror and this is family car and I have a kids they are using the screen all the time.

I was driving the speed limit on a sunny day and heard a loud pop and glass breaking which was my sunroof exploding. There is no damage to my roof to indicate anything hit my vehicle.

Sunroof exploded out of nowhere. Extremely loud. Sounded like a gunshot.

I was at a complete stop. There were no obstacles around me or oncoming. When I pressed the accelerator nothing happened for a full 3 seconds, until my vehicle jolted forward at an excessive speed. Brakes were not working.

Excessive heat coming from all vents and under steering wheel after long time driving. I am very concerned that the vehicle may be caught on fire and then cause injuries or casualties.

Sunroof glass just exploded
