The electronic driver's seat motor and track assembly failed completely on my 2021 Toyota Sienna (VIN: [XXX]) at less than 18,000 miles. The seat is permanently seized in a fixed position. This creates an immediate safety and crash-protection hazard, as drivers of different heights cannot safely adjust their distance from the steering wheel airbag or properly reach the pedals. Toyota corporate is refusing to repair this premature manufacturing defect on a known problematic seating system, leaving a severe safety risk unresolved.

My liftgate has been making loud noises upon closing. The dealership checked it and diagnosed that the trunk door is mis-aligned, leaving a gap so that the door WOULD NOT SECURELY CLOSE. I was referred to the body shop to have the shocks and hinges changed. Further discussions mentioned this was a common problem with the Toyota RAV-4 where the hydraulics fail causing a bad alignment therefore affecting the hinges. Although my vehicle is a Toyota SIENNA, I had asked if this was caused by mishandling on my part (ie, slamming/ forcing the door or stuffing the cargo) but the technician mentioned that there was nothing I could have done to prevent it nor done to have caused the hydraulics to fail or go bad. There were no lamps or alerts that warned me of the problem other than the "scraping noise" upon closing that was getting louder ever since. The problem had been assessed and confirmed by the body shop.

FAILURE: Blind spot monitor module failed due to a corroded internal electrical connector. The failure disabled both the Blind Spot Monitor (BSM) and Rear Cross-Traffic Alert (RCTA). Both remain inoperative. The failed component has not been replaced and is available for inspection. SAFETY RISK: Two active safety systems are disabled. The vehicle no longer warns of vehicles in the blind spot during lane changes, and no longer warns of cross traffic when backing out of parking spaces or driveways. WARNING LAMPS: Yes. Multiple warning lamps illuminated simultaneously in February 2026, including BSM and RCTA malfunction messages. No prior symptoms or gradual degradation. CONFIRMED BY DEALER: Yes. A Toyota dealer diagnosed the corroded connector as the cause. Repair quoted at approximately $2,500-$3,000. Repair not performed. INSPECTED BY MANUFACTURER: Diagnosed by a Toyota dealer. Goodwill assistance was requested from Toyota and declined, on the stated grounds that the vehicle had not been regularly serviced at a Toyota dealer. NOT A WEAR ITEM: A sealed electrical connector that corrodes to failure is a component defect. No step in the manufacturer's published maintenance schedule inspects, services, or protects this connector — no owner action could have prevented it, and service history has no bearing on a connector that no service procedure touches. Vehicle purchased new September 2021; failure occurred at approximately [XXX] of age. REQUEST: Request that ODI evaluate whether the BSM sensor and connector design used on this vehicle is inadequately sealed against moisture intrusion, resulting in premature failure of two active safety systems.

- 07/13/2026· SERVICE BRAKES
FAILURE: Brake control system. Vehicle intermittently surges forward while braking at low speed, most often through a curve — the brakes momentarily release and the vehicle lurches before braking resumes. Appears to occur during the transition between regenerative and friction braking. Vehicle available for inspection. SAFETY RISK: Unpredictable momentary loss of braking at low speed, in parking lots, residential streets and curves where pedestrians and other vehicles are close. Driver cannot anticipate it. WARNING LAMPS: None. No lamp, no message, no stored trouble code. Present since early in ownership; purchased new September 2021. CONFIRMED BY DEALER: No. Reported to a Toyota dealer in 2022 under warranty. Dealer test drove, could not reproduce the intermittent condition, took no action. Also reported in writing to Toyota in August 2022; no substantive response. MANUFACTURER REMEDY: In May 2024 Toyota issued TSB T-SB-0047-24, a brake control module software update for this exact low-speed braking condition on 2021-2022 Sienna Hybrids. Warranty had lapsed, so it was applied at owner expense in late June 2026 at ~156,000 miles. The defect persists after Toyota's own remedy. The surge still occurs, including within the past week at ~157,000 miles. REQUEST: A TSB is not a recall — owners are not notified, and the software remedy did not eliminate the defect on this vehicle. Request that ODI evaluate whether this condition warrants a defect investigation and recall.

Unexpected failure of the acceleration pedal to accelerate from a complete stop to a go at an intersection. The electric vehicle (EV) motor began accelerating up to about 3 mph than instantly had a failure to accelerate, even with the gas pedal continuously pushed to the floor. After about 4 to 5 seconds the engine kicked on and began accelerating. The failure seemed to occur during the EV motor swapping over to the gas powered engine. This has been the fourth occurrence and can be extremely dangerous at intersections with oncoming traffic. No fault codes or check engine lights came on.

1. The rear underbody air conditioning (AC) lines and their supporting structural mounting brackets have failed due to severe corrosion. Specifically, a heavy steel mounting bracket has rusted excessively, causing localized galvanic corrosion at the point of contact with the adjacent aluminum AC lines. This structural and material failure caused the aluminum line to erode, crack, and leak high-pressure chemical refrigerant into the environment. The vehicle, failed components, and detailed photographic evidence of the galvanic corrosion and rusted bracket are fully available for inspection upon request. 2. The failure presents multiple safety and health hazards: •Environmental and Inhalation Hazard: The high-pressure leak of mobile air conditioning refrigerant (R-1234yf or R-134a) releases a hazardous chemical compound directly beneath the cabin. •Defrost and Visibility Failure: The rapid loss of system pressure completely disables the vehicle’s climate control and window defrosting/demisting capabilities, severely compromising driver visibility during inclement or humid weather. •Structural Degradation: The severe rust and erosion of the underbody mounting bracket mean structural components are failing prematurely on a 2021 model, creating a risk of loose or dragging underbody debris at highway speeds. 3. The physical failure (loss of refrigerant and severe physical corrosion) has been visually confirmed. However, the Toyota dealership service center actively refused to document the cause. However, photographic evidence clearly reveals the distinct, localized galvanic corrosion occurring exactly where the rusted steel bracket contacts the aluminum line. Further, Toyota’s highlander model had this same problem which was addressed through T-SB-0021-26. 4. The vehicle was inspected by an authorized Toyota dealership which acknowledged the leak but refused to provide a written technical breakdown. 5. Rust, corrosion, and loss of cooling ability.

The contact owns a 2021 Toyota Sienna Hybrid. The contact stated that while driving at an undisclosed speed, the contact heard an abnormal splashing sound inside the vehicle. The contact stated that while the vehicle was parked, there was water coming from underneath the doors. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact related the failure to Technical Service Bulletin: 0121-20 (Sloshing or Splashing Noise Caused by Water Inside Doors); however, the vehicle was not covered under the TSB. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 22,500.
- 06/03/2026· SERVICE BRAKES
My 2021 Toyota Sienna Hybrid has an intermittent and dangerous brake failure where the brakes suddenly release pressure during normal braking. When slowing down—especially at lower speeds or approaching a stop—the brake pedal briefly loses resistance and the vehicle surges forward as if the brakes let go. I must immediately re‑apply hard pedal pressure to avoid rolling into traffic or another vehicle. The vehicle as a result can stop up to six feet past the intended stopping point in some instances. This issue is unpredictable and has occurred multiple times. It creates a serious safety risk. Toyota performed T‑SB‑0047‑24 (Brake ECU Reprogramming) on my vehicle, whereafter the brakes seemed to function normally for several months, but the problem resurfaced and occurred threee time in one week in May of 2026, which prompted me to bring it backk to Toyota for another look. The dealer has been unable to reproduce the issue and therefore has not repaired it. The veicle has been returned to me, and continues to have the problem intermittently at a random frequency. Toyota corporate Brand Engagement Center has been notified, and a case was opened (Ref # 260528002416). This case was closed however after telling me that the dealership connot reproduce the problem, therefore they cannot repair it. This appears to be a brake control defect involving the hybrid brake‑by‑wire system. Because the failure is intermittent and leaves no diagnostic codes, it is extremely difficult for the dealer to diagnose, but the safety risk is severe. I'd like to advise that I have owned and driven earlier hybrid models (2012-14) that never exhibited this type of brake failure. I'd also like to point out... an internet search of this problem reveals that this problem seems to be prevelant in newer Toyota hybrid models. This was confirmed by the service manager at my local dealership. I have not been informed of any continuing engineering efforts given the failure of the TSB.
