“Gas lid would not release after pulling the lever. This has happened mulitiple times prior without me realizing it was a problem because the second time I pulled the lever it would release - this last time it would not release even after multiple pulls - I had to push the gas door forward with the palm of my hand and then pry open”
NHTSA complaint #10734111, filed 2015-07, 1,200 miles“My 2015 Subaru Legacy has at different times (at idle in gear, coming up to a red light while moving, pulling into a parking lot or driving at 45 miles an hour) accereated on its own and would not slow down untill I put it in nuetral. I have to drive with my hand on the shifter at all times to put into nuetral. I bought the car new in 2015 and have 13900 miles on it now in july 2016.”
NHTSA complaint #10881699, filed 2016-06, 13,500 miles“Almost every time I fill up with gas, when the gas pump shuts off there is a back splash of gas out of the tank. I would say anywhere from 1 to 3 ounces of gas splashes out. Depends on the pressure it's being filled at. I talked to my dealer about it and was told that is common for Subaru Legacy's.”
NHTSA complaint #10693000, filed 2015-03, 1,000 miles“At 300 miles, coming off highway, slowed down to 5 MPH and went thru toll booth. I then stepped on gas, had hesitation, no response then acceleration. Happened again on 5/11/15 when I had 900 miles. Came off highway on to local streets. This time had 5-7 big hesitations over 10 minute period. Very dangerous because I was making a u-turn and car hesitated then accelerated as I was making u-turn !! Returned car to dealer. Do not want to drive it until fixed.”
NHTSA complaint #10716292, filed 2015-05, 300 miles“From a slow roll making a right hand turn. Put my foot on the gas peddle and got no reply for about 3-4 second then the card pulled out very fast this often. Most of the time from a stop at a stop sign. No movement for about 3-5 seconds. Also, then jumps out fast. Took back to dealer. They could not find the problem. June 18, 2015 called main office of Subaru.. They sent me to a local dealer. June 24, 2015. Car with them for 2 days. No response. Very scarey.”
