NHTSA — Power Train: Manual Transmission: Floor Shift Assembly 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.

2004 Saturn Ion Owner Comments

problem #1

Aug 292005

Ion 4-cyl

  • Manual transmission
  • 17,160 miles


I have a 2004 Saturn Ion red line with a manual transmission (only transmission offered). I was shifting from first to second gear, in traffic, and the entire shift knob assembly came off in my hand. The knob fell to the driver's side floor, causing me to look down. I was able to stop the vehicle in time to avoid the car in front of me. The vehicle is then difficult to shift, and the pull up for reverse feature was very difficult. There are a number of complaints on www.saturnfans.com. the "fix" is to epoxy the knob back onto the shifter bar as it is a press fit design (no mechanical lock or fasteners).
