I just picked up a 2017 WRX 6-speed. My 2005 WRX is still in the garage, to be up for sale soon. I drove the 2005 off the lot brand new, so I've had quite a few years behind the wheel of a WRX.
The dealership where I purchased the car has a policy that they don't allow test drives on the WRX models, you have purchase the vehicle first. I have to admit, now in my 40's, this seemed like a mighty strange policy. Fortunately, I had already test driven a 2017 at another dealership. On to the issue.
On the way home with the new 2017 WRX, I'm feeling brake pedal vibration/chatter on very light braking, when the brakes are *barely* engaged, at slow speed - it almost feels like there is gravel in the rotor (something I experienced once with my 2005). When I hit a bump at the same time, and maybe even turning a bit, it feels like the brake AND clutch pedal are loose, and I can hear a light noise of what reminds me of loose brake pad clicking. When I pulled into work the other morning, I put the front right wheel up onto the sloped driveway entrance, and when it tweaked the car, a loud "bong" came from the front right of the vehicle, like the spring just seated itself. Over some bumps, the front end has that feel like a link or tie rod is starting to wear, that ever so slight clunk and extra feedback in the steering wheel.
With the car running, and stopped, not in gear, I can abruptly press the brake pedal and hear some obvious noise of something engaging incorrectly for just a second - I can repeat that over and over.
My primary concern is heading to the dealership only to find folks who don't feel this is a serious issue, or just can't find anything wrong. I had this same thing happen with a rear end clunking noise in my 2005 that I identified just 30k miles in - the dealership wrote it off to standard noise (not before incorrectly diagnosing it as a loose spare tire, that I had already removed) - I drove it like that for over 100k miles when a small town mechanic found that the rear trunk latch was just loose (!!!).
Anyways - any advise here on how to best way to approach dealerships when a guy's brand new Subaru has a problem, would be much appreciated. I'll post back after Saturday - hopefully with good news. I'm a long time WRX owner, and this new vehicle is fantastic in so many ways, just so disappointed with the brake issue.
