“The DCM (Data Communication Module), also referred to as the Starlink telematics module, has failed. This failure is causing a continuous parasitic battery drain, which rapidly depletes the vehicle’s battery even after charging or replacement”
“Chronic issue with the vehicle draining batteries. I’ve gone through 4 new batteries in the time I’ve owned the vehicle and find that they die in what’s sometimes only a few months after purchase”
“This is the 4th battery in my 2016 Outback limited. Three battery replacements in 6 years. See mechanic's report that the charging system tested good but the battery was bad”
