Battery Light on but Batt/Alt tested fine Code P0622
2000 Dodge Intrepid 2.7L 112,000 miles
Ok, so my fiance mainly drives this car and she was on her way to work today and the battery light came on. She drove about another 10-15 highway miles with it on to work. Got to work, turned the car off then back on and battery light was gone. I went to her job and switched cars with her, at first the battery light was not on, after about 5-10 minutes it came on again.
The car does not act sluggish or anything with the light on and it hasnt died at all. I stopped somewhere, got back in started it up and light was gone. I went to Advance Autoparts and had the battery and alternator tested, everything tested fine. The guy said the light means the battery is close to being dead and I should probably replace it soon, however, I just did a couple weeks ago, this is a brand new battery, furthermore the car isnt dying.
Last night I just so happened to pull codes because my CEL has been on for about two months. I only had P1684 (battery disconnect within last 50 starts, which my car ALWAYS has this code, and code P0455, which is an evap leak (my fiance likes to forget to put the gas cap on tight enough sometimes.)
So when i got home from everything today, I get an additional code P0455, which I looked up on here in some other posts, and people seem to point it out to having to do with the alternator.
So my obvious question is......What the heck is wrong with the car.
Addtl Info: When I was on the highway, once or twice the car seemed to have a slight stutter to it, but it was barely noticeable and only happened once or twice in succession.
Also, I had a problem about two months ago, with the car cutting off while driving, then sometimes not wanting to start at all. Ended up replacing the battery and everything has been A-Ok for the last 2 months.
