2011 Toyota Prius Owner Comments

problem #5

I am 5'4" tall and like the seat in an upright position. There is no way I can adjust the headrest so that it allows me to sit upright and not have my head forced forward and down by the headrest. I understand this is a new "safety" regulation. This regulation needs to be changed so people of my height can drive the car without their heads being forced down. I use a foam cushion between my back and the seat to compensate for this terrible design flaw. I would like to be able to buy a car that is both safe and fits me. It is not safe to drive with my head forced down. By the way, your next box indicates bad website design. I want to put in N/a or always since there is no one time for this issue, but the stupid web designer doesn't think that should be an option.

Prius 4-cyl

I am an excellent driver. I purchased this Prius in the summer of 2011. We (my wife and young daughter) were proceeding on juanita drive N.E. in kirkland, wa. My wife and I agree that our speed was approximately 30-33 mph and that there were approximately 3+ car lengths between us and the vehicle in front of us. The weather was dry and sunny. Suddenly, a vehicle three vehicles ahead of us stopped to make a left turn, and the two vehicles behind it were able to stop. I immediately applied my brakes to the floor as soon as I observed the stopped vehicle ahead. I felt no response - no gripping of the brakes or gripping of the wheels to the road, no squealing, no skidding, no sense of the brakes slowing the vehicle in the three seconds I applied them. Due to vehicles in the opposing lane, a narrow road and no shoulder (a ditch with telephone poles on the right), I was forced to design the least harmful impact - my front right corner to the rear left corner of the vehicle in front. The impact tore open the right front of the vehicle, shattering the windshield next to my wife and causing her legs to fly up and strike the dashboard, injuring her legs in several places. Her airbag did not deploy. My 7-year-old was in her car seat in the back seat. The larger split back was behind her. The back became unhinged at impact and flipped forward, forcing my daughter's upper body forward. She sustained minor facial injuries. While it is possible that the airbag non-deployment was appropriate (I am not certain of this), there is no question that the braking was soft, squishy, non-existent, and the back seat should not have become unhinged.

The driver's head seat, of the Prius 2011, pops up when driving on a high way especially if the road is a bit rough.
