I got my 2001 Kia Sportage new, in 2001 and never had any major issues other than reg maintance stuff. I can drive the car locally around town durning the day with no issues. However long distances say over 30 miles in a straight shot my car starts to lose power til it dies, like it was running on just battery power. At times I also noticed that if I go over 50 mph, it dies faster. Now, at night, with lights, I can barely drive 5-10 miles before it dies. It's even done it when I charged the battery to full. Yet, When Autozone hooked it up to there thng they use, they say the battery is fine, starter and alternator is fine. I am at a loss. I know when its about to start dying cuz the internal clock starts to dim then goes out and bomb, car dies. But durning the day then the clock starts to din a bit, it then get bright again and I have no issues. Anyone have any ideas, suggestions??? Has anyone had this happen???
