I recently had my 2018 STI with only 350 miles serviced at Faulkner Subaru due to being misaligned from the factory. Upon return of my vehicle, I noticed my trip meter had registered 15.7 miles, my boost gauge's peak PSI had been reset to zero, and the SI-drive system had been switched from intelligent to sport mode. The mileage is the least of my concern as I can understand the need to thoroughly test the alignment. But the other two indicate to me that the vehicle had been driven hard and/or carelessly by a technician during the recommended 1,000 mile break-in period, with the boost gauge being reset to hide the peak that it hit while driven in sport mode.
I contacted both the service manager and my service advisor to discuss the situation. I was told by the service manager that the technician denied changing these settings and may have 'accidentally bumped a button'. For one, is the technician really going to admit that they did this? Not likely. And also, both of these items require intentional actions to reset (the boost gauge is a press and hold for approximately 3 seconds and the SI-drive mode requires turning a knob by hand). Neither one, let alone both, are likely at all to be set accidentally.
It's extremely disappointing to have custom-ordered my STI, waited two months for it to arrive, and followed the break-in recommendations religiously... just to have someone else treat it carelessly in the first few hundred miles. Now I have to be concerned about issues that could arise in the future from that sort of treatment. I've purchased 2 vehicles and have had 3 of my Subarus serviced at Faulkner Subaru, but needless to say I will likely be taking them elsewhere from now on.
