Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

NHTSA — Engine And Engine Cooling: Engine: Gasoline: Belts And Associated Pulleys Problems Seal Of This Might Hurt Notes: The Saturn Ion was a compact bundle of hurt wrapped up in a cheap, plastic shell. With so many defective components and a safety rating that a bicycle would be ashamed of, it’s a blessing this car only lasted five model years.

The 2003 (and 2004) Ion was cursed with GM’s flawed attempt at a continuously variable transmission, known as the VTi. It had such a high failure rate that a class-action lawsuit was filed against GM, eventually prompting a settlement and a warranty extension. GM discontinued the VTi for the 2005 model year – surprise, surprise.

The 2003 Ion was also part of one of the largest and most controversial recalls of all-time. A defective ignition switch in millions of GM vehicles could accidentally turn the car off and disable important safety components like the power steering and airbags. The problem resulted in at least 13 deaths, but what made it worse was that GM knew about the issue for 10 years before doing anything about it.

So was the transmission warranty extended? Yeah. Was the ignition switch recalled? Eventually. Is this car safe to drive? Not really. Honestly, you’re better off looking elsewhere.

problem #2

Nov 242007

Ion 4-cyl

  • Automatic transmission
  • 73,000 miles


The timing chain broke on the vehicle. All I did was go to start it up and it wouldn't start. I had to have it towed to a Goodyear but they couldn't fix it. So right now it is being looked at by a mechanic. He said that the timing chain is broken and because of the breakage I now have to have the valves replaced as well as the thermostat, the fuel pump and the head gasket. All of these were damaged by the chain. This is now costing me approximately $3000. All of which is caused by a faulty belt that Saturn installed on their vehicles.
