NHTSA — Power Train: Automatic Transmission: Control Module (Tcm, Pcm) 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.

Ion 4-cyl

  • Automatic transmission

While driving approximately 65-70 mph on an interstate, my vehicle just died - no warning. This was the second time it had happened. There is no power & must be pulled off the road & restarted. This is a very dangerous condition - rapid deceleration on a congested highway could be fatal. When I took it to the dealer, they told me nothing showed up on the computer, therefore nothing was wrong with the car. Talking to the Saturn customer service rep returned the same response. I am very afraid to drive this vehicle, it is a very hazardous condition and the car is only one year old. It is a 2004 Saturn Ion. The dealer refuses to replace anything because "nothing is wrong.
