I just came back from the Svc Center Federal highway. My car is 15k Mileage, 1yr 7 months.
Was told the same thing, need to pay for the batt as warranty only 1 yr or 20k.

Firstly i have been using istop for only 20% of my total time as i usually off it.
My car only 15k mileage, hardly use istop, and now battery weak/low.

Svc center asking me to change for 500+ after the discount.

i said NO. why should i change... totally waste of money and no savings benefit from it.

but arent the istop and car batt two seperate batteries that work independently?
im still able to start my car without issues although the istop light is orange blinking and warning sign logo is out.

WHat if i permanently want istop disabled without a batt?

I dont see a point of needing to change the istop battery to only manually disable the feature everytime i start my car.
