I bought my 2004 Prius two months ago. A few weeks ago it after I had it turned off for just a few minutes, I started it up, and the whole bottom row of maintenance lights came on (on the dash). The engine didn't seem to turn on. I powered off, tried again, and it started. The clock had been reset, however, and the GPS DVD had to reload. There were a few similar occurences in the few days after that, with the same oddities repeating themselves, but not all in the same occurrence. One day the smart key wouldn't unlock the car anymore, and the car wouldn't start at all. (Red light on the smart key would still come on when I depressed the unlock or lock button.) Thirty minutes later both worked again, although clock and GPS were reset again. I basically ignored the problem and even thought it might have gone away, but then my car just flat-out wouldn't start a few nights ago. I called roadside service for a jump, drove the car on the highway for 30 minutes to recharge the battery and got JUST to the fully recharged point (literally by seconds) before I had to get home to my child. I've been watching the trip info screen the past few days, and the battery never gets up to fully charged. Mostly I drive in town with frequent stopping--no more than 5 or 10 minutes of a stretch of driving these past few days (after the 30-minute highway recharge). There have been no more strange occurrences in these past few days, and I also read that I may have caused my battery problem (pre-jumpstart) by not turning off my headlights before powering off the car. Since the jumpstart I haven't done that; I intentionally turn them off before powering off the car or opening the door. Today, however, the car wouldn't start again. It's currently dead until a friend can jumpstart it tomorrow. I'll give it another 20-30 minutes on the highway or until the trip info screen shows me the battery is fully charged. But...what's going on? The battery was supposedly brand new when I bought the car two months ago. Did I destroy it by leaving my headlights on so many times? Any bets on whether or not I'm going to have to invest in a new battery? What's my best course of action here? Take it to a dealer? Or could a non-dealer service shop help me out? I'd appreciate knowing what the most economical steps to take would be here. Money is a concern right now. Thank you!
