The front drivers side exterior turn signal light stop functioning about 2 months or so after the bulb was replaced, now it doesn't work at all. The panel inside the car had shown me that same turn signal light had been malfunctioning for some time blinking extremely fast back to normal until it finally needed to be replaced. I can't get my safety check done because the turn signal lamp is inoperative. I wonder if a drl jumper kit needs to be added, can you please direct me? The car was in motion making a left turn on the highway.
While driving in pre-dawn hours (headlights & defrosters on), started smelling something melting or burning. Then instrument panel lights went out for a few seconds. Instrument panel lights then came back on & started flashing on & off really fast. At that same time, door locks started locking & unlocking repeatedly on their own. Burning & melting smell was getting stronger. As I was pulling over, I entered a more well-lit area and saw smoke accumulating inside car near roof & top of windshield. Shut car off immediately.
I was driving at night on a country road when a deer ran out in front of me and the car struck it. The car sustained some front end damage and the cabin filled with smoke. The seat-belts locked up but the airbags never deployed. Now the airbag light is on and the seat-belts are locked up. It concerns me that with everything that happened that the airbag should have when off.
Strong gas smell & started noticing poor gas mileage and it got worse. Then notice it is leaking gas by the rear driver side tire. Also the running lights automatically come on during the day but not at night.
I purchased my 2004 Saturn Ion in April, 2004. In June, 2004 my right turn signal stopped working, causing my running light on that side not to work either. In July, 2004 when opening up the hood to refill windshield wiper fluid, the hood latch inside the car came off in my hand. On dec 22, 2004, the brakes on my 2004 Saturn Ion failed to work cause me to go through a stop sign, which resulted in a accident with another car. Both cars were only moving about 15 - 20 MPH, but on impact the whole right (passenger side) side bumper broke up and was on the ground. Leaving a big gapping hole on the right passenger side of the car. No recalls have been placed on defective brakes, as of this date. …
After 5 years my 2004 Saturn Ion will not start when the temperature is below +10f. There is power ( new battery ) and no fuel issue ( clean fuel system and filter ), but after 10 to 15 minutes and a couple of hesitant engine turns, it starts. No one needs an unreliable vehicle where winter temps last several months. After replacing the anti-sway bar, both headlight assemblies as well as other annoying problems ( instrument lights out, cabin fan noisy ) I will never ever buy another Saturn . I took the problem ( out of warranty of course ) to Saturn of rochester and was told it was a faulty ignition switch, a common problem for this make and model year. Since it is not a safety issue, no recall was issued and I would have to pay at least $275 unless "something else" came up. Being late for work ( public safety and volunteer fireman ) or my wife and children is not an option for me. …
Dt: the turn signals worked intermittently. Also, thee car would not start. The vehicle started after multiple attempts of turning the key in the ignition. The vehicle was taken to a dealer, who repaired the problem. They were aware of an ongoing issue with the ignition. The turn signals were repaired under a recall. Since then there was one incident where they did not work properly. The consumer felt they did not complete the repair. There was a TSB on the issue that the dealer used to correct it. These problems began in December 2004, and were thought to be corrected by the dealer. Last week after filling the gas tank up the vehicle would not start. The contact made several attempts to start the vehicle and was unsuccessful. The contact's husband came and turned the key in the ignition and the vehicle started. The vehicle was not returned to the dealer at that time. …
When I turn my car on the parking lights and front turn signals starting blinking really quick like strobing. I can turn my left turn signal on and it will blink inside hearing the normal ticking. If I turn my right turn signal on it the arrow on the inside blinks slower and makes no ticking sound.if I push on my brake the light work probably and the ticking sound on the right turn signal inside starts. If I put my emergency brake on it works properly. The strobing of the front outside parking lights stop. If I turn my parking light on and drive with them on everything works properly. I know this has something to do with the recall. It is effecting my car so bad that my radio display light blinks also. So it is getting feedback from this problem before I have a wreck. I am a single mother with 2 children.
I have a 2004 Saturn Ion and there was recall (04V547000) in this vehicle in regards to defective turn signals. Approximately 3 weeks ago I contacted Saturn and was told that there was never a recall on this item. I researched this further and called Saturn again and now was told that there was a recall and the work has been done to the vehicle before I bought it. I have also read articles and people were stating that they had to have the work done a few times because what was done to the vehicle didn't fix the problem. Saturn is now telling me that they cant do anything about the defect and that I would have to pay for the work.
In 2005 a recall was issued for the 2004 Saturn Ion front headlamps. I had the recalled parts replaced. For the past few months my left blinker has gone out about five times. I have replaced bulbs, had the dealer replace the sockets, and am now about to have the wiring harness replaced. The dealer said that no one else has had this problem. However, I have been researching the problem and have found hundreds of the same occurrences online and have seen other Saturn ions around town with the same blinker out. I believe this problem is not normal wear and tear. I believe it is directly related to the 2005 recall.

Remedy: Dealers will replace the drl/turn signal bulb on both the left and right front side and inspect for and add a drl jumper kit if not present. The recall began November 17, 2004.
