Just received a notice from Honda that problems have occured with the Auto Stop engine shut down on 2021 Ridgelines. They are extending the starter and relay warranty to 10 years with unlimited mileage. This is good news. For those owners who would like to change the default setting for the Auto Stop to off, instead of the factory's on, there is a plug and play available from Idlestopper. It is an easy and quick solution.
