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.

The contact owns a 2003 Saturn Ion. While the vehicle was being inspected at the dealer, the mechanic discovered that the turn signals failed. The dealer stated that the vehicle was previously repaired according to NHTSA campaign number: 04V547000 (exterior lighting), but the failure recurred. The manufacturer was not notified. The failure mileage was 167,000.

Failure of GM to notify me of 3 recalls on 2003 Saturn Ion. It is possible that this work has already been done, but I cannot tell at this time and would like this problem investigated. Recalls are: NHTSA campaign id number: 04V547000 NHTSA campaign id number: 04V003000

When it rains or snows, my driver seat and floor gets wet. There are no water stains around the sun roof nor is there any water damage on the drivers' door. In new england, the car is non-functional in the winter and spring because of this problem. I have taken it to the local Saturn dealership and they have refused to fix it. 2) I have had to replace my front turn signals 3 times in 1.5 years. I am almost convinced it is a socket problem and not a lightbulb problem. 3) I have had to replace the brakes and rotors twice within a 12 month period. In that time. I have only driven 17,000 miles. Once is understandable. Twice is expensive and ridiculous.

Front right turn signal bulb 'bright' / 'high' elment burned out. Bulb was oem wagner 5702ka. Bulb base was blacked, had signs of overheating. Both left and front headlight assembly outer lenses have changed from clear to translucent imediately above turn signal bulbs, perhaps due to overheateing. Dealer said a problem was discovered and fixed in the later 2003 Ions. Dealer offered to diagnose and install a 'resistor and harness' kit at my expence. This is obviously a design error and should be fixed at Saturn's expence. May be a potential fire hazard.

Ion 4-cyl

  • Manual transmission
  • 1,000 miles
My 2003 Saturn Ion 2 sedan has had at least eight front turn signal or daytime running light bulbs fail since the car was delivered in February 2003. The bulbs in question are manufactured by wagner, and are type 5702. Failure of front turn signal lamps creates the potential for an accident, since oncoming traffic has no indication of my intent to turn. The local dealership has examined the car on three or four occasions, and has found no objective reason for the failure. Replacing the bulb corrects the problem, typically for several months but in several instances for less than a week. The bulbs in question are not available from national parts chains such as Napa, advance auto parts, autozone, and pep boys; the only source is a Saturn dealership, which charges approximately $8 for a replacement lamp. I have since experimented with using a sylvania 3157nall, which is apparently identical and is rated for use in daytime running light applications. It functions identically to the oem part, except that it appears to last much longer (it has yet to fail after several months), and is readily available from any automotive parts store for about a quarter of the cost.

I have had repeated problems with the exterior front lighting on my new 2003 Saturn Ion which is a safety hazard. On 5/15/03 I took the vehicle to the albuquerque Saturn dealership to fix the front driver side running light and left turn signal. They replaced the bulbs, but I had to take it to the dealership again on 7/18/03 after having driven it less than 100 miles for the same problem. This time they replaced the entire headlamp assembly. Then again on 9/29/03 I took it back to the dealership to have the passenger side front running light and turn signal replaced. I talked with the sales manager ben vigil and the service manager justin greenberg. I complained that I've spent more time at the dealership for unscheduled maintenance than routine maintenance, and I was concerned I had bought a lemon. I told them that if my turn signals aren't working properly, that is a safety issue. Mr. Greenberg told me that he probably gets two customers a day with the same problem (which shocked me). He said Saturn has sent out new bulbs to the dealerships which they claim will solve the problem. We'll see.
