I was on my way to work when the vehicle in front of me came to a complete stop. I was approx. Three car lengths behind her (which is plenty of distance at 25mph) when I applied my brakes though nothing happened. They made a grinding noise (like the pads were gone, but they are new ceramic pads). I ended up hitting the vehicle in front of me. I got a citation for following to close, which is $260, my insurance was increased by over $100 a month, I had to pay for her car plus $3750 of damage on mine. She didn't have insurance and was driving on a suspended license.when I told the officer what had happened with my car he just looked at me as if I was stupid. This is a major problem that is and has cost people a lot of money, not to mention being without a vehicle.

The throttle body stuck open causing it to rev to excessive rpms and then would finally die. This happened while driving at highway speed in 7/08. The throttle body was replaced and then once again it failed, this time sticking closed causing the car to die in an intersection. This was in 3/11 (this year) with only 73K on it total miles ( only 30K on this throttle body). When we received the new part this time, it had been obviously redesigned with a vent allowing corrosion not to occur. This is a real hazard when you have no control over engine speed while driving. With the redesigned part ( a Toyota/Scion part) it is obvious this was a "known" problem, yet no recall was ever issued or received.

My 2005 Scion Tc surges/lurches forward when resuming from a stop. The amount of pressure you apply to the gas pedal has no effect on how the car is going to move forward. The problem was very intermittent and hard to notice but started happening more and more often as of Aug./Sept. 2008. In mid Sept. I almost rear ended the car in front of me taking off from a stop light. I took the car to the selling dealership and the service mgr. Went on a test drive and said he noticed the problem at least 5 times in a few mile drive. When I picked my car up 2 days later the service invoice stated "unable to duplicate" and it was recommended I have a 30,000 mile maint. Done I had just had those services done 1 month earlier and they were aware of that. It was then recommended that I switch gas stations and use high octane fuel and use a fuel injection cleaner purchased from any gas station, then if no improvement further diagnostics would be needed but no codes in the ECU. I followed the recommendations for over 2 months and no change. Went back to the same dealership and was told nothing could be done and even with an extended warranty the regional service mgr sent to "inspect" my car did not inspect it and refused to authorize the repair and submit the claim under the extended warranty. I also at this time reminded them that the speedometer does not work all the time. And when it doesn't work and the car is idling the speedometer shows a speed of 5-10 miles per hour, yet while driving shows a speed of 0. I also pointed out that the drivers side pillar airbag cover they fixed weeks ago is hanging loose. It comes off every time you shut the door. This has been repaired at least twice before. They refused to acknowledge this problem as well. My car has or is having about 95% of the items displayed in your service bulletins, seatbelts, airbags, fuel injectors, window controls, sun roof, air condition and tire pressure monitor system. And the dealership aware of all of them.
