Went in for a battery replacement, and they gouged my sister over $900 just for replacing the battery and doing a supposed, computer update...now the start/stop engine function when idle at stoplights, doesn't work and some other features like eyesight function disabled etc....they all worked fine before the service. She took the 2019 Subaru Forester back to them...they supposedly did a factory reset(without even pulling it back into the shop)...this fixed nothing...they didn't even take it for a drive to test the problem features. What are my sisters options, to getting these problems fixed, without being screwed over again! I can honestly say that I will be not stop without justice for this disgusting treatment of human being! I've since talked to multiple women who were gouged badly and ended up selling their Subaru's and will never buy one ever again! Someone has to stop this untrustworthy dealer.
