2018 Subaru Impreza Electrical System

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.

Failure of the starter motor, should be able to get the faulty part from mechanic. This rendered me unable to start my car and required a tow, thankfully not from the side of the highway. Confirmed faulty with tow driver and mechanic. The part has only been inspected by mechanic who mentioned this was the third starter motor failure he has seen on Subaru Imprezas. No warnings, though the car struggled to turn over earlier in the day.

I LEASE A 2018 SUBARU IMPREZA, WHICH CURRENTLY HAS ABOUT 14,000 MILES. SINCE JANUARY 2021, IT'S BATTERY HAS FAILED MULTIPLE TIMES. I HAVE TAKEN THE CAR TO THE DEALER (DUNNING SUBARU IN ANN ARBOR, MI) AND THE SERVICE DEPARTMENT HAS INSTALLED 4 NEW BATTERIES. THEIR DIAGNOSIS HAS BEEN THAT AS LONG AS I DON'T DRIVE MORE OFTEN AND FARTHER (IN THESE VAGUE TERMS) MY CAR'S BATTERY WILL CONTINUE TO FAIL. THE LAST TIME I TOOK MY CAR TO GET IT FIXED AFTER IT STRANDED ME, ON APRIL 16, THE DEALERSHIP AND SUBARU OF AMERICA'S CONSUMER ADVOCATE OFFICE BOTH SUGGESTED THAT I PURCHASE AN OFF-MARKET BATTERY TENDER TO RECHARGE THE BATTERY. THIS MEANS THAT THEY ANTICIPATE THEIR CAR BATTERY WILL FAIL WITH MY CURRENT DRIVING NEEDS. IN OTHER WORDS, THE VEHICLE IS UNRELIABLE. BUT FROM THEIR PERSPECTIVE, I AM AT FAULT FOR NOT DRIVING MORE.

OEM BATTERY FAILED AND LEFT DRIVER STRANDED IN NOV 2020. DEALER REPLACED BATTERY AT THAT TIME. DEALER HAD TO REPLACE BATTERY AGAIN TODAY, 04/02/2021 BECAUSE IT WAS ALSO FAILING. DEALER WOULD NOT ACKNOWLEDGE THAT ISSUE WAS WITH CAR. SIMPLY STATED THAT THEY WOULD CONTINUE TO REPLACE FAILED BATTERIES IF WITHIN WARRANTY PERIOD. EXTREMELY DANGEROUS. WHEN BATTERY FAILS, CAR IS UNRESPONSIVE TO ANY/ALL COMMANDS.

PROBLEM WITH THE IGNITION SWITCH NOT WANTING TO ENGAGE, WOULDN'T TURN THE KEY AT ALL. HAS BEEN A PROBLEM FOR THE LAST FEW MONTHS WHERE I HAD TO PLAY WITH IGNITION TO GET IT TO TURN OVER
