“Car would not accelerate upon entering the highway after pushing on the gas pedal the car wouldn't do anything . I was able to get off to the side and missed being hit from behind from on coming traffic...I notice check engine light and flashing cruse control light... Second time some weeks later it did the same thing this is very dangerous because you never know when this will happen.”

NHTSA complaint #11024196, filed 2017-09, 136,000 miles

“I was driving with my 6 month pregnant wife. No indication of impending problem. Suddenly the at oil temp indicator lighted up and split second I loss engine power with steering became stiff. Good thing I was not in the freeway yet and was able to safely pull over with residual momentum. …”

NHTSA complaint #10499559, filed 2013-02, 133,000 miles

“While driving the check engine light came on and the cruise control started flashing, with no response from the gas pedal, only a high idle. Had the check engine light cleared and everything was fine. Out of town for the second occurrence same thing happened, now Subaru has the car and I was told the engine harness has to be replaced at a cost of $1883.36. It seems to me that this should be covered under my extended warranty.”

NHTSA complaint #10485855, filed 2012-11, 80,000 miles

“I had run into a few small problems this winter, like my steering wheel not turning when the car was cold, but I experienced my first major problem while my vehicle was stationary, but had been running. I was going through a drive through, had to put my car in park, then when I went to shift it back into drive, nothing would happen. It was stuck in park. I don't think the problem was temp. Related, it was about 40 degrees outside. After turning the car on/off four or five times I was able to get it going, but my headlights went out, which I thought was strange. …”

NHTSA complaint #11075502, filed 2018-02, 168,565 miles

“Was in cruise control around 45 MPH, came to a stop and ce and cc lights illuminated, and gas pedal was dissabled, so a fellow motorist helped me push the car away from the intersection. After turning engine on and off several times throttle control came back and I could drive home (ce and cc lights still on). I replaced the gas pedal and reset the lights. Similar problem reoccurred on way to work, ce and cc lights came on but still had throttle control and cc was inactive. I suspect a disconnect in the drive by wire logic for the gas pedal versus the cc.”
