2022 Toyota Sienna Hybrid

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

I own a 2022 Toyota Sienna with approximately 67,680 miles. The vehicle began displaying warnings for **Blind Spot Monitor Malfunction, Rear Cross Traffic Alert Malfunction, and Parking Support Brake Unavailable**. A Toyota dealer diagnosed the problem and found significant corrosion at **both rear blind spot monitor connections**. The wiring harness connector pins had corroded/broken off inside the blind spot monitor sensors. The dealer recommends replacing both blind spot monitors and the rear bumper wiring harness and recalibrating the system. The estimated repair cost is **$3,945.84**. I am concerned that both sides of this safety-related system experienced severe corrosion on a vehicle that is less than five years old. These components are not scheduled maintenance or wear items. I have also found reports of other 2021–2022 Toyota Sienna owners experiencing blind spot monitoring failures involving corrosion of the rear sensor/connectors, including another 2022 Sienna at approximately 65,000 miles. Toyota's Brand Engagement Center has documented my complaint but declined to review the repair for goodwill assistance because the vehicle is outside the basic warranty and has not been serviced exclusively at Toyota dealerships. I am filing this complaint because the corrosion simultaneously disables multiple driver-assistance/safety functions and appears unusually premature. I believe NHTSA should investigate whether corrosion or inadequate protection of the rear blind spot monitor connections is affecting other 2021–2024 Toyota Siennas.

I am reporting a potential safety issue involving the passenger-side power sliding door on a 2022 Toyota Sienna. On XXX, my [XXX] child was outside the vehicle in a wagon while the passenger-side sliding door was closing. He reached toward the vehicle, and his fingers became trapped near the front edge of the sliding door, closest to the front passenger door. The power door did not stop or reverse after contacting his fingers. It continued closing, clicked shut, and fully latched with his fingers caught in the door. We immediately opened the door and removed his hand. Thankfully, he was not seriously injured, but the incident had the potential to cause a severe hand or finger injury. I am concerned that the obstruction-detection or pinch-protection system did not detect an infant’s fingers in this location. I am submitting this complaint so the incident is documented and can be compared with any similar reports involving Toyota Sienna power sliding doors.

Stitching on the driver seat is tearing. Under normal wear. The vehicle is just out of the 3 year/36,000 warranty period. If the seat continues to degrade it will not be safe for future use as it worsens.

The car will occassionally lurch forward while braking. It's somewhat random but most often happens when going down a slight hill. My best guess is that there is an issue with the transition from regenerative braking to mechanical braking. It feels like the vehicle momentarily looses contact with the brakes and that the brake pedal has to be pushed down another inch or two to reengage. My concern is that if this happens at the wrong time that I will get in an accident. This has happened ever since I bought it. It's not very often, maybe once a week. Speeds have been variable from under 25 to highway speeds.

We brought our 2022 Toyota Sienna in for service January 2024 for the driver's seat. The seat would make really loud popping noises that sounded like something was loose when the seat moved forward and backward. We brought the vehicle in, and the service technician discovered that the driver's seat assembly was loose and cracking. The technician removed and replaced faulty components of the seat assembly under warranty. The seat starting having the same issues recently, and we are concerned of an on going safety issue given the instability of the driver's seat. The dealership informed us they will not repair the seat under warranty.
