Reports have circulated that the BRZ/FRS has had some reported idle issues due to, what Subaru and Toyota says, are cam timing issues within the programming of the ecu. Seems Toyota and Subaru are dealing with it differently, with Subaru offering a reflash and Toyota/Scion only suggesting it can be brought to the dealer for a reflash if at 100 miles or less, but if over that, a new ecu will be installed. Can’t say the mileage thing makes sense on the surface, but I’m sure they’ve got their reasons.
Found a video of it online.
Hopefully just the typical new car teething pains that lots of manufacturers have with brand new models. It does stink for the owners, but looks like each company has relatively quick and easy solution already.
