What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact stated that while driving alone at 70 MPH and attempting not to hit tire tread in the road, she crashed into the median, her vehicle drove into a ditch, the vehicle spun twice, and then crashed head-on into a tree where it came to a stop.
There were no warning lights or messages prior to the incident. The airbag system has not yet been inspected or confirmed defective by a service center, but I am willing to make the vehicle available for inspection if needed.
Had there been a fire I wouldn't be making this report! Doors need to be operable regardless of situation when none of them are jammed from an accident!
The impact of the crash caused the vehicle and the shelf to extensively damage the dry wall of that area of the garage, as well as to damage the pedestal supporting the house water heater, which resulted in the water heater detaching away from the wall and being destroyed.
The air bags did not deploy despite the front end collision. At the body shop, upon tear down the passenger side rail was damaged as well as the air bag sensors were crushed. One would think if the sensors were crushed the air bags would have deployed prior.
While driving approximately 40 mph and attempting to stop the vehicle, the brakes failed. As a result, the vehicle rear ended the preceding vehicle. There was no warning indicator illuminated. The air bag did not deploy. A police report was filed. There were no injuries.
Front row seatbelts did not engage, nor did front airbags deploy. Our sienna hit the stopped vehicle in front of us upon impact as well. Only right side curtain airbags deployed and middle row seatbelts restrain. This resulted in multiple injuries to the front row passengers, including a severe concussion.
Lost steering ability from some cause after a lane change, on a highway, vehicle continued into the shoulder and would not allow correction into the lane. Possible cause in my opinion may have been a l. Front tire blow out or a steering linkage issue or possibly the stability control system. The vehicle was new.
