Prius 4-cyl

The Prius failed to stop when brakes were applied; instead the car did a lurch when the brakes were applied and then accelerated forward causing a 4 car collision; luckily no one was injured. Made Toyota aware of the problem, when they investigated they of course found nothing wrong with the vehicle's brake system.

Prius 4-cyl

  • 29,100 miles


While pulling into a parking slot in a parking lot, which was on a slope, I applied the foot brake without any response whatsoever. The vehicle gained enough speed to jump the small stop-curb and hit a concrete wall next to it. The damage to the front of the car was just over $4000. I thought I had missed the pedal. On June 12th and 15th, I had two more incidents of the brake pedal going all the way to the floor while either at slow speed or stopped. My dealer says it was a problem on the 2010, but he has not seen it on a 2011. My wife now refuses to drive the car.

Unnecessary minor injury producing design my Prius, which I like, has several times given me a minor bruise that lasts for a couple of weeks. The front passenger doors, at the bottom corners, end in a sharp right angle. In contrast, many other car doors have a slightly rounded bottom corner which have never injured me. As I am walking around the Prius, loading and unloading for example, that sharp corner seems to catch my shin and bruise it. I am in my 70's and guess that these minor injuries are more likely to happen with children and seniors. If this was a needed element of design, then I would not call this to your attention. However it seems to be primarily poor ergonomics on the part of the designer. If the injury potential of sharp corners was brought to the attention of car manufacturers, perhaps, when designs are changed, the safer corner could be incorporated at essentially no cost and numbers of future minor injuries could be avoided.

Prius 4-cyl

  • 7,400 miles
We purchased a 10 month old Toyota Prius on March 16nd 2012 with only 1367 miles. The prior owner who was leasing this car returned the car due to mileage inconsistency..... on Oct 5th 2012, I was driving on sunny dry day at 22mph the vehicle in front of me slowed down. I stepped on the brake to slowdown but the car did not stop. When I stepped on the brake it did not respond immediately, I applied complete pressure to the brake however the car still did not slow down enough and I hit the car in front of me. Per the report from Toyota the speed went down from 22mph to 5mph at the time of the impact. I do not agree with the Toyota report that I only stepped on the brake for 2 seconds as it was much more... before the accident the brake was much harder and less forceful pressure made the car stop after the accident the brake feels softer and more pressure is needed to make the brake work. This is an almost brand new car with 7K miles on it however I do feel safe in this car anymore after this accident and I fear for my life and public safety. What will happen I drive on a highway at 60mph and the brake will not work?? Toyota denies any technical error with the car and blames the accident on me. There are plenty of reports of similar accidents reported by consumers on this same issue here: townhall-talk.edmunds.com/direct/view/.F0db60B.
