Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“On routine oil visit change, dealership informed me the head gaskets were leaking slightly but didn't need immediate repair. I had noticed no symptoms. On next visit for an unrelated problem, was told they needed immediate repair at a cost of more than $2,000. A quick online search confirmed that this is a common complaint among Forester owners. I let the dealer make the repair but complained to Subaru corporate, which wrote off some of the cost but still cost me hundreds to fix.”
NHTSA complaint #11196457, filed 2019-04, 107,000 miles“While in my driveway, I started the engine, stepped on the brake, put the vehicle in drive and it accelerated. I swerved to miss a trailer parked in front of me, pushed harder on the brake, the vehicle stopped, the engine raced for a few seconds and then idled normally. I got out, looked at the floor mat and it wasn't touching the accelerator. It hasn't happened since, but the car doesn't get driven much.”
NHTSA complaint #10609402, filed 2014-07, 68,800 miles“I was heading to work on rt 80 w in nj when my car's engine began to make a knocking sound. It would not accelerate, and the steering wheel became extremely difficult to turn. As soon as possible I got into the right-hand lane and exited rt 80 via exit 34b, rt 15n towards sparta nj. I knew there was a gas station at the exit and was just barely able to pull in when the car died. At that point the steering wheel wouldn't turn at all and the car died. …”
NHTSA complaint #10897232, filed 2016-08, 152,000 miles“Hello- I am experiencing continued issues after recall: 16v-738. I began attempting to resolve this issue in september of 2016. The issue impacts the secondary air system and my vehicle would not pass ca smog. I have to have a passing smog to renew my ca registration. I failed smog and sent the vehicle to my mechanic. My mechanic performed diagnosis and determined stored p2441 and p2443 codes (secondary air valves open). Around the same time, october 2016, Subaru released recall: 16v-738. This addresses a single relay in the secondary air series. …”
NHTSA complaint #10939754, filed 2017-01, 17,000 miles“Problem of sudden acceleration while stopped in traffic with vehicle in gear. This happened twice. Both on city roads. Once at a traffic light. And again while waiting for traffic ahead of me. Feared I would collide with cars ahead of me, but extremely firm pressure on brake pedal avoided this. Also have cel on. Code indicates misfire on cylinder 4. That was determined at the service center of burdick's drivers village in cicero, where I purchased the car used almost 2 years ago. The service advisor at drivers village told me there was nothing further they could do. …”
