2022 Toyota Sienna Hybrid problems

“Concern 1: My 2022 Toyota Sienna intermittently experiences an unexpected forward surge while braking. When I press the brake pedal to slow or stop the vehicle, I sometimes feel a sudden forward pushing or acceleration sensation before the vehicle slows down. The behavior is unexpected and concerning, particularly when approaching another vehicle, intersection, or obstacle. I am concerned that this condition could increase the risk of a collision Concern 2 – Clicking/clunking from driver's side There is also a repetitive clicking or clunking noise from the driver's side of the vehicle during stop-and-go operation. The noise can be heard when the vehicle stops and then begins moving again. I reported this condition to Nalley Toyota in Roswell and requested that it be inspected as a potential warranty issue. I was advised that I would need to pay a diagnostic fee.”

“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…”

“I am reporting a recurring safety-related defect involving driver-assistance and steering-wheel controls on my 2022 Toyota Sienna Limited, VIN [XXX] ry 8, 2026, I brought the vehicle to Parkway Toyota in [XXX] bec [XXX] tion” warning appeared and cruise control stopped working. The dealer diagnosed the issue as related to the 12V battery, replaced the battery, and advised that the condition was resolved. The same malfunction later recurred. I returned to Parkway Toyota on March 18-19, 2026 for the same problem. I reported that the issue had reappeared after driving in cold conditions in Canada and that when the vehicle was warm there were no warning lights. The dealer diagnosed DTC U042381 (“invalid data received from instrument panel cluster”) and replaced the hybrid vehicle control ECU. I was told the repair was complete. Within about two days, the identical “LTA Malfunction” warning returned again and cruise control was again disabled. In addition, a broader failure then developed involving the steering-wheel-mounted controls: the steering-wheel buttons stopped responding, the instrument display became stuck on one screen and could not be changed, the…”

“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. Vehicle: 2022 Toyota Sienna VIN: [XXX] Incident date: XXX Incident location: [XXX] Affected component: Passenger-side power sliding door”
