This vehicle has an electrical issue from time to time seemingly out of nowhere. There is no power steering it just shuts off sometimes it'll stay off for an hour sometimes it'll stay off for weeks and I can't figure out how to fix it. It randomly fixes itself same can be said for the air conditioning And the driver side, headlight all of these electrical functions, seemingly turn themselves up or down for no apparent reason.

2005 Saturn Ion. Front and back blinkers will not blink. I have replaced all bulbs and entire light assemblies. The vehicle is not inspectable because it has to have all lights working. This has been an intermittent problem and the cause of the light failure is unknown. The vehicle has been with an auto mechanic/electrician for over 2 weeks now and is very frustrating and unacceptable. Saturn has to find a way to repair the problem at their cost. It should not be the responsibility of the customer to have the problem repaired, because it is obviously an internal malfunction. Not only have I heard several complaints regarding the Saturn and the difficulty in finding repair parts, but to find someone willing to work on them is not easy either. This has been an ongoing expense that appears to be never ending . …

A few years ago my left turn signal went out for the first time but I just replaced it which took a few trys before it actually worked, over the last couple of years I have had more problems with that turn signal working. Everytime I have to replace it, it is a hassle trying to get it to work for it to only go out again within a week or two. I am out there again today replacing this thing. I have read about recalls on 2004 ions, have there not been any for this problem for the 2005?
