“My 2010 Subaru Legacy automatic...while accelerating on an incline lost all acceleration, car acted as if it was in neutral, no response from the throttle. Lights were still on, no warning light indicators. Pulled over, turned off the engine and restarted. Problem has not occurred since. Dealer says he can't recreate the problem and the diagnostics reveal no error codes. Afraid to drive my new Subaru.”
NHTSA complaint #10356951, filed 2010-09, 15,000 miles“While crossing a busy street I was forced to brake hard and quickly because the car ahead of me suddenly stopped. My Subaru's engine then stalled. I was almost hit from both the rear end and from the side because I couldn't start my car fast enough. The dealership indicates that this is due to a bad torque converter on the CVT transmission. This is a known issue with the 2010 Legacy, but they will not and the NHTSA won't force them to do a recall. However, my car is 16,000 miles outside the extended warranty they established when they found out about the problem. …”
NHTSA complaint #11221402, filed 2019-06, 116,000 miles“Vehicle stutters and frequently stalls when coming to a stop. The more aggressive the braking, the likeliness of stalling becomes higher. The vehicle needs to be put into neutral to be restarted. This also occurs more frequently in colder temperatures. The older the vehicle the more obvious the issue becomes. Currently 99500 on a 2010 Legacy. The dealership has confirmed that the converter needs to be replaced, but Subaru USA is unwilling to offer support due to the vehicle being outside the 'extended warranty'. …”
NHTSA complaint #11394710, filed 2021-02, 99,500 miles“My Subaru is equipped with CVT, when fuel is appealed engine revs, pause, then drop in rev and acceleration. This is a safety concern when passing, cornering, or any other point when in a rolling start.”
NHTSA complaint #10515376, filed 2013-06, 63,500 miles“I had a episode of sudden unintended acceleration while I was driving in the highway. If I would let the brake pedal go, my car would probably escalate its speed to maximum until it crashes. The RPM was almost 5 even though I was applying the brake. I could not make it stop by applying the brakes at all . I only could make it finally stop when I changed the gears to neutral and them to park and finally turn the engine off. I was lucky I was in the highway and when I got in the first light it was green, other wise an accident would've happened.”
