2022 Toyota Sienna Hybrid Problems

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.

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.

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.

While braking, when the vehicle switches from regenerative braking to conventional, the vehical lurches or momentarily speeds up before stopping. All while brake petal is depressed.

The contact owns a 2022 Toyota Sienna Hybrid. The contact stated that while driving 25 MPH, the vehicle crashed into the rear of a stationary vehicle; however, the air bags failed to deploy. Additionally, the ABS failed to activate as designed. The contact sustained a back injury upon impact; however, medical attention was not sought. The vehicle was towed to the residence. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 84,751.

When purchased "As Is", an airbag deployment was disclosed but not that the front passenger side airbag had not been replaced. In December of 2025, an SRS Airbag warning appeared. Upon inspection, the mechanic discovered a "resistor" had been inserted in the SRS cirucuity to avoid disclosure of the absence of a replacement airbag. The replacement airbag was installed at my cost of $1,578.09 +8% Ohio Sales Tax. I contacted the selling dealer, Toyota of Bedford (OH), in early January 2026 but have not received a response. The other dealer disclosed in the Carfax (likely responsible for the omission of the airbag when the vehicle was repaired in July of 2022) is Suburban Toyota of Troy, MI.

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 cruise-control buttons stopped functioning, and the radio volume could no longer be changed from the steering wheel. This appears to be an intermittent but recurring defect affecting driver-assistance functions and vehicle controls while driving. The vehicle has now had two repair attempts for the same general condition, and the problem has not been resolved. Repairing dealer: Parkway Toyota, [XXX] .

I was pulling out onto a main road, pressed the accelerator and "not much" happened. The car accelerated to maybe 5 mph and no faster. Took my foot off the accelerator and pushed it to the floor. No response. It was like the vehicle only ran on EV mode and did not turn the engine on. In a second or more returned to normal and could not reproduce what happened. On coming traffic had to break. There was enough room to pull out under normal situations.
