Subaru Australia use those scores as a gauge stick as to what promotions and discounts they provide each dealership.
You'd think that would be incentive enough to provide decent customer service, but incidences like this are fairly normal.
It's easy enough to use the customer service scores as a carrot to dangle as they dealerships are desperate to receive high scores.
FWIW, I don't work at Subaru or a dealership, but have had a family member work at one. That in itself didn't stop that dealership trying to pull the wool over my eyes.
I think it's all just window dressing though. The guy who called me was so rude and arrogant that I ended up getting the service manager to call me (who actually said he considered it acceptable for the other guy to abuse me down the phone if I wasn't giving him the answer he wanted...). He also said that they only have about 1 in 10 customers who rate them poorly and "that's good enough so we won't change anything" and that all the negative complaints about them online is "fake news".
Ended up complaining to Subaru directly as it's the second issue I've had with Tynan. Previously I'd taken the new Liberty - 5000ks old at this point - to them after it refused to start. They just charged the battery (not questioning why the battery had died) and sent me on my way apparently without testing it (where of course it refused to start again at 6 on a Friday afternoon). Was a real battle to deal with them. Subaru never even got back to me (after I lodged the complaint with a guy who said he didn't even know how to take a complaint). So the surveys do seem somewhat pointless.
Anyway... off topic
