Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Driving a 2010 Subaru Legacy on a narrow street with a 90 degree turn. Entering the turn the clutch pedal was pressed disengaging the clutch, the brakes were applied slightly - the car stalled as the engine died. Since it was a turn and the car has power steering the nose was in the opposite lane before it stopped. There was no accident.”
NHTSA complaint #10343183, filed 2010-07, 800 miles“Start car , engine cold, or at least not fully warmed up. While driving, push clutch in , take foot off gas to shift. Engine revs drop to near zero. Engine stalls. Its intermittent. But some anecdotal evidence that hot weather exaggerates the issue. Seems to happen less when engine is fully warmed up. Dealer has recreated the problem, but said they can do nothing about fixing it. This car has died in intersections twice and also on open road in traffic.”
NHTSA complaint #10343751, filed 2010-07, 1,200 miles“Engine has stalled (completely shut down) 5 times at low RPM, leaving all systems off, including power steering. Conditions of each stall: low RPM, vehicle decelerating, clutch engaged, shifter in neutral, hot ambient air temperature, air conditioner on. More prevalent (4 out of 5 occurrences) when engine is cold (within minutes of starting). Engine restarts normally. This is a safety concern, as the stalls have occurred twice while performing a turn across oncoming traffic.”
