Credov's researched list of the 3 faults the Subaru Impreza WRX GR is known for (2007–2014), 2 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: On a gentle full-throttle pull from 2,500-3,500 rpm, feel for a stumble or misfire.
Why it matters: A cracked ringland is a known weak point of this engine and usually ends in a short block or forged-piston rebuild, a bill that can run into the thousands; it is far cheaper to find cylinder 4 running weak before buying than after.
What to look for: Shift quickly through every gear and reverse, cold and warm, listening for a grind or whine.
Why it matters: This 5-speed is the known weak link in an otherwise strong drivetrain; grinding or a broken gear usually means a gearbox rebuild or replacement, so a quiet, clean shift pattern is worth confirming before you commit.
What to look for: Crouch and check the lower doors, sills and door and arch edges for chips, touch-up paint or rust spots.
Why it matters: A chip left untreated on a steel panel turns into a rust bubble, which is a far more expensive repair than a stone chip caught early.
