Pivot bolt inside steering wheel came loose, was warned it had dropped to where it could interfere with brake linkages. Filed complaint with toyota and never heard back so filing this complaint. (1) a large bolt inside a sealed area should not be able to come loose if installed correctly (manufacturing error - single instance or systematic?) and (2) a loose bolt should not be a risk for a possible catastrophic…

I was driving on i-45 at 55 or 60 mph and the brake pedal went to the floor. It is still that way, brake fluid level is ok. Toyotacare plan is expired. Is there a recall for these vehicles? Thanks *tr

I own a 2012 prius with the technology package, including radar adaptive cruise control. I believe these same radar sensors are also used to detect imminent collisions in front of the vehicle, even when cruise control mode is not engaged. About a month ago, while driving north on interstate 5 in downtown seattle at approximately 60 miles per hour, and without cruise control engaged, my prius went into "imminent…

When i took it to the dealer for repair, the dealer determined that rodents had eaten through a number of the electrical systems because of the soy based wiring. (i understand now that it's "biogradable soy based…

I tried pressing the brake pedal harder and making sure that i had proper foot placement and it felt like the car accelerated at that point. Since the car was not slowing down i was unable to make the turn and ended up crossing the road diagonally and going up onto the curb. Once the car was over the curb and in the grass the brakes finally engaged…

The vehicle emits a repetitive 'woo......woo.....' that varies with speed/wheel revolution (something rubbing during each revolution). To the best of my ability to tell, it sounds like the groan is coming from the rear-passenger side. The sound is usually present after the car has sat overnight or after prolonged parking and last for 100-300 feet of driving. I've even heard it after four hours of being parked at…

It seems that the vehicles brake system releases and you have to reapply the brakes. I have had the vehicle inspected by the dealer 2 times and they have been unable…
