Consumer Description

When using the a/c while the Auto Idle Stop is engaged, the engine will shut off and not restart. This issue does not happen immediately, at the first cycle of being activated, it's after 3 or more cycles of the AIS being in use, like driving in stop and go traffic for instance. The issue reminds me of a low/dying battery when it happens. Now when I turn off the A/C, the car starts right up like normal. Also if I don't use the A/C, the AIS cycles like normal, like in traffic, l'll have no problems with its performance.
