NHTSA — Vehicle Speed Control: Accelerator Pedal Problems

CarComplaints.com Seal Of This Might Hurt

CarComplaints.com Notes: Ahh, the 2004 Saturn Ion: defective transmission, deadly ignition switch, temperamental power steering and a cheap plastic exterior that won’t protect you in a crash. What more could you want?

The 2004 Ion was part of GM’s massive ignition switch recall where it was revealed they waited 10 years – and let 13 people die – before doing anything about it. It also features GM’s now infamous VTi continuously variable transmission. Let me tell you, the only thing the VTi did continuously was fail on its owners. GM scrapped it after only two model years.

problem #2

Sep 142004


  • Manual transmission
  • 150 miles
While driving accelerator pedal, which was not bolted down, came off, causing the driver to lose shoe and it was wedged between the floorboard and the pedal. There was nothing there to secure the pedal. There were no end caps to keep the pedal in place. Consumer asked for another vehicle equal in value to the one that was purchased. Dealer offered consumer a vehicle of lesser value because they could not locate one of the same value.
