My wife's Santa Fe, 2002, 6 Cyl 4wd has strted to show starting problems.\nThe other day we went to the drive-in movies. The vehicle was not\nrunning, and she had to use electrical accessories at times for our baby,\nincluding a bottle warmer.\n\nWhen leaving, the vehicle would not start. It demonstrated all the\nclassic low battery signs, slow crank, clicking and such. After a bit of\nswearing and "now what do we do's" It slowly cranked and started.\n\nNow, today, my wife got in, started just fine. Drove to the mall. Left\nthe mall , again started fine. Drove to post office.... with AC cranked,\nand a bit of traffic delays, a lot of stop and go, gets to the post\noffice, goes in and comes out. Tries to start truck..... dead... real\nslow crank, click..... she swears, calls me, and while talking to me it\nstarts.\n\nI suspect the battery. the electrical loads should not hurt a healthy\nbattery. I figure it was borderline. Whith the loads both at the\nmovies, and the stop and go driving with AC cranked would pull more juice\nthan the alternator could provide during these conditions. As such I\nplan on replacing the battery.\n\nNo my actual questions:\n\nThis is 2 year old vehicle with the factory battery. Can the battery be\nbad already?\n\nAnd... this vehicle is "hyundai certified".. did the people going over it\nmiss the possible weak battery... we've had the truck only 2 months.\n\nAny input folks?\n\nThanks!
