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.


definitely annoying

problem #1

Ion 4-cyl

  • 25,106 miles
Failure of a wiring harness in a front door that controls windows, mirrors and door lock. A 2004 Saturn Ion with 25, 106 miles had 5 broken wires in the drivers door. The left rear door has no power at the window switch. This failure is due to an inherent design flaw that forces tiny wires to bend 2 times at 90 degrees and be slammed by a door!! think of the safety of unlocking a door in a panic situation or driving with a window down in rain, sleet, cold, etc., and a fuse is not the problem.
