Went out Friday to record 3 CD's to the HDD. During the recording of the 3rd CD, the radio blanked out. Turned key off from accessory, turned back on and it came back so I finished recording. Ejected the CD and it blanked out again. Tried turning ignition on/off a couple times, nothing. When I tried to start it, all it did was click. Got the charger out and it showed the battery at 20% capacity. Charged it to 67% because we had to leave, started ok the rest of the day. But, since I was out, I just bought another battery and replaced it the next morning. Even after quite a bit of driving, when I put the old battery on slow charge the next morning, it was at 82%. It finally came up to 100%, so I'll let it sit a couple days and see what I've got. We got the Terrain Jan. 10, so 19 months for the battery.
Normally get at least 2 or 3 years. :
