    Question Adaptive cruise control issues--post-dead-battery

    So, I'm not quite sure why my two-year-old battery died while my 2007 was in storage this winter (and, yes, I had it connected to a tender, and it apparently died six weeks beyond the warranty) but I did manage to get it home. On the way back, my adaptive cruise would occasionally (but not always) flash the red warning in the HUD as I approached the car ahead, even on relatively slow approaches. Other times, it would work fine, slowing down in line with the car ahead. Is some sort of recalibration required?

    If youíre still using the same battery itís most likely causing your problems. Also your battery may just need a really good charge! Last year when I pulled Roxy out after winter season storage, I ran it to the garage for Pa State inspection and they tested the battery and it was good but very low, and it was on the tender too!

    Thanks! I got home and discovered I could not start the car again; the battery appeared to be still dead. I had a friend come over with a high-powered charger; it got to 83%, at which point it started flashing BAD BAT. Ironically/unfortunately, I was six weeks past my two-year warranty, so I went to get a different brand with a three-year warranty, and it appears to be good to go.
