Tl* the contact owns a 2003 Saturn Ion. While the vehicle was being inspected at the dealer, the mechanic discovered that the turn signals failed.

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. …
At the time my Saturn was involved in an accident it was under 30,000 miles and still under warrenty. I was driving on a busy highway and my accelerator got stuck. At the time I could not see what was holding down my accelerator. It was a piece of panel that came off partially that was holding the accelerator really hard and it was stuck making my pedal stuck almost all the way to the floor. I tried to slow the car down with both feet on the breaks and the emergency break to no avail. I didn't turn the ignition off because I had cars on all sides of me going 50-70 MPH. It was when I came to a red light that I realized my car wasn't going to stop and I had no other choice but to hit an SUV and my car kept trying to accelerate and push the SUV out of the way. That is when I turned off the ignition. I had to turn off the ignition before another accident occurred. The SUV was damaged. …
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. …
The front left light of my 2003 Saturn Ion has gone out repeatedly. Upon careful inspection, the bulb itself is not burnt out. When signaling left, the blinker in the vehicle and the left tail light blink very rapidly. As the front left turn signal light is also the daytime running lght, I have a burnt out left daytime runnung light which is a possible saftey hazard. The vehicle was brought in to the dealer three times. The first two times I was told that the bulb was defective and that they had just replaced it. I know this is not true as I tried to troubleshoot the vehicle before bringing it to the dealer by taking the right "good" buld and seeing if it would turn on in the left light assembly. It did not. The third time I brought it in the service manager told me they would just replace thw whole assembly as they have been having problems with them. …
Headlights do not project a beam as far as when vehicle was new. Nightime driving on rural roads during deer season is hazardous. Saturn dealer has installed updated wiring harness to correct repeated premature daytime running light failures and coincidently or not, the headlights have performed poorly since then. Discussed this with Saturn dealer and service manager said he has lots of complaints about poor headlight performance from the Ion. I know my Saturn Ion headlights performed satisfactorily at first, but have degraded. The electrical system and my vision are both fine. The supension has not been altered and the vehicle has not been involved in an accident. I replaced factory halogen bulbs with sylvania silverstar 9007 bulbs and illuminated field is brighter, but still does not extend down the road much farther. …
Saturn Ion 2 model year 2003 was serviced for 2004 turn signal recall back in 2005; in the past 16 months I have had the driver side turn signal bulb changed 4 times because it stops working, and have changed it 2 more times before the most recent series of incidents. As of today I changed it a 5th time and it still does not work. This is a hazardous condition particularly since it fails repeatedly. Now I have been told that the body control module might have a problem May need to be replaced. This is an issue for hundreds of Saturn owners; the recall should have fixed the re-occurence of the original problem but has not.
Headligh movement, distracting to dirver as light beams hit object the beam appears to be gittering. Distracting also to vehicles in front of you as drivers continue to look in mirror. Saturn dealership stated they do not have a fix, that is is this way by design. Headlight mounts to mounting panel with (2) pins going through upper ear in mounting panel and then upper and lower ears on headlight assy. And into lower ear of mounting panel. Appears to much play in the pin to mount area, this will worsen over time as metal pin in plastic ears will become larger from the shaking. This occurs even of smooth road beds.
