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. 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.

Horn is very difficult to actuate, requiring hard pressing one of two specific small horn logos on the steering wheel air bag cover. These are hard to find in an emergency, and impossible to quickly find when driving at night. This has resulted in a few near misses, because the horn could not be activated quickly enough to alert another driver that they were leaving their lane. I had to swerve evasively to prevent the accident. Saturn dealer in past has said that horn works normally. This is the only vehicle that my wife or I have driven in thirty years that has this problem. It appears to be a poor design, and something should be done to rectify it. The horn is useless in a suddenly developing emergency situation. Date is not specific; as form would not allow submission without a date. I have not had an accident yet, but this should be rectified before someone has a serious accident.
