What 2018 Subaru WRX owners say
Engine & cooling
I have been experiencing a strong fuel odor both inside and outside the cabin when starting the engine. After several months of experiencing this issue, I recently had my vehicle fully inspected by an authorized Subaru dealership, and they confirmed a critical fuel leak issue. The dealership discovered that the high-pressure fuel pipe is leaking, as confirmed by a camera inspection of the engine bay. They have deemed the vehicle unsafe to drive and have strongly advised against further use due to the potential fire hazard. It is important to note that my vehicle has never been involved in an accident, and no prior mechanical work has been performed in the affected area, which suggests this may be a manufacturing defect.
I bought a 2018 Subaru WRX with 61,000 miles, After driving it 6,000 miles with engine spun a rod bearing, requiring a complete engine replacement. This is a vehicle that in the previous 4th generation of the car, it was recalled for this exact issue. the total repair bill for this fix is $11,720.43. This is on a car with 67,000 miles. 7,000 miles over Subaru's manufacture warranty. After speaking with a few service advisors at Subaru. it is my belief, that this is a known issue with this model.

Steering
Unknown. I am unsure of the issue. However, there is an issue. & it is very dangerous... This has happend about 5, or 6 times now. Sometimes when I am making a turn (I believe it is related to the braking), My steering wheel locks up (as if the key isn't in the ignition). It only lasts for a second, or two. But again, it is very dangerous. & I am at my wits end trying to figure out what the issue is. I am unsure of the issue. But, there is an issue. & it is dangerous for myself, & others. I am trying to limit my driving, but I still have bills to pay, & jobs to do. So please get back to me at your earliest convenience. Thank You, & God Bless.
