| Description of the problem | I write to highlight some unusual behavior exhibited by my 2009 hybrid highlanders braking system which i purchased in may 2009. In short, in certain driving conditions, there is a slight delay/pause between depressing the brake pedal and any braking force applied by the braking system. The delay is momentary and i've experienced this to last no more than half second (. 5 sec.) at most i've noticed that this occurs mostly in a situation where i have forcefully applied the brake. It has seemed to recur mostly when driving down a decline. It does not occur during situations where i smoothly and evenly apply pressure to the brake pedal. During my 5,000 mile service at the glendora toyota dealerships, i mentioned the behavior (as well as a soft grinding sound during low speed travel) but they could not find anything wrong in their tests. My wife and i have both independently experienced behavior this several times and the problem is still recurrent. I have decided to report this behavior after reading todays ap article by ken thomas and yuri kageyama (us government investigating brakes in 2010 prius) which described similar problems with 2009 toyota prius vehicles. Although the problems my particular vehicle has exhibited have thusfar been slight when compared to those reported in the article, i feel compelled to report the issue and i certainly hope that the problem does not surface during a time the extra braking time is needed. Aside from the above-described behaviors, the vehicle has operated without problems and my family and i are otherwise very satisfied with our purchase and hope we can rely upon this vehicle for many more years. If i can be of any assistance to either the nhtsa or toyota corporation, please feel free to contact me. |
