NHTSA Complaint #11441890 — 2017 SUBARU OUTBACK

I purchased a used 2017 Subaru Outback Premium in January 2020 from Johnson Subaru in Raleigh, NC. It was a Certified car and had a brand new Subaru brand battery as part of the prep before the sale. That battery failed on Aug 23, 2021...less than 18 months old. A Subaru dealer agreed to replace it under the 2 year battery warranty. The free replacement Subaru brand battery that was installed in my Subaru Outback in August 2021 failed on November 28. 2021...less than 4 months old. The tests at O'Reilly Auto Parts on Nov 28th show the battery was delivering 0 volts. The alternator was tested, too, and it was providing 14 volts to the replacement battery. When Subaru installed this battery last August the Subaru Service Adviser told me that there was no warranty on a replacement battery because Subaru would only replace it once. Why aren't replacement parts guaranteed? They are brand new. Subaru batteries are defective and cannot supply sufficient voltage to the car's electrical system. They don't last as long as their 2 year warranty. I have pictures of the battery test and the alternator test below. Poor quality Subaru brand batteries are a known issue and Subaru should take action to provide better replacement parts and the replacement parts should also be warranted. I can't depend on Subaru brand batteries. I bought a battery from O'Reilly while I was there at a cost of $159.95 plus tax and core. I would like for Subaru to reimburse me for at least part of that expense.
