Consumer Description
2018 Impreza, beginning around 2020, has had three dead or damaged batteries (2x OEM and 1x aftermarket) and the car is now on its fourth battery (aftermarket). Vehicle couldn't sit for more than a few days without needing jump started. Dealership performed parasitic draw test and concluded the Data Communications Module (DCM) was the source of the parasitic draw and pulled the DCM fuse while I await back ordered parts (the DCM and DCM battery). From my research, older DCM units rely on 3G cell service that's no longer available and the DCM keeps attempting to phone home telemetry data, but can't, and drains the battery. Thankfully I have an extended warranty to cover this replacement but feel like Subaru needs to be more proactive in solving this issue for its customers by declaring a recall.
