Scion FR-S TSB Issued for Abnormal Engine Chirp
First generation cars tend to have some teething issues, and Scion‘s latest baby, the FR-S is not without it’s quirks. Owners of the FR-S can breathe a little easier thanks to a new technical service bulletin (TSB) that resolves an annoying noise emitted by the car.
The bulletin states, “some vehicles may exhibit a high pitch chirp or squeak noise from the high pressure fuel pump assembly when the engine is fully warmed up and idling.” The issue apparently affects any FR-S with a VIN# ending in 09026 or lower. Newer vehicles are not affected.
The bulletin explains that technicians should warm up the car for ten minutes and see if the car exhibits the chirping or squeaking noises. If it does, then the vehicles high pressure fuel pump assembly will be removed and replaced.
However, the replacement high pressure fuel assembly has the same parts number as the old one. It’s not quite clear what is wrong with the original installation of the high pressure fuel pump, but apparently this should fix the noise that owners are reporting.
There’s no news yet on Subaru releasing a similar TSB for the BRZ, or if the issue is affecting international Toyota GT 86s.

Barely bought my FRS, have a little over 1k miles on it and it's fkn embarrassing driving a brand new car with squeeking noise from the engine!! What a mistake, last time I'm ever buying a Scion but we need to get a resolution for this!!
I just bought a '14 frs monogram edition with 16k miles on it. Never a chirp until about 100 miles ago at roughly 17k miles. The most annoying thing ever and dealership said I have most up to date fuel pump. So I'm basically screwed on my new car that looks amazing but sounds like shit?
