Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Would go to start car and it wouldn't start. Multiple days thought I was doing something wrong g leaving something on, got battery checked they said it was ok just low. It kept doing it, went on for like 2-3 months . Finally I had enough and bought a new battery. Since it happened and replaced battery vehicle idles high like 1-2 in park.”
NHTSA complaint #11416745, filed 2021-05, 35,000 miles“Forester was parked in under ground parking garage for between one and two weeks. The battery was completely dead, no sound at all when I tried to start it. The only door that was locked was the rear hatch door. Neighbor brought a battery charger and got the Forester started. Following that, I drove it to the local Subaru dealer and ask them to check and see if anything was draining the battery. They check everything and did not find any problem. …”
NHTSA complaint #11322297, filed 2020-04, 11,735 miles“The eyesight had been manipulated to a warning even when there's no obstruction while driving forward, while backing up it gives a warning that someone or a vehicle is adjacent to my car. These are just a few of the problems I encounter. I have an idea who's behind this. But I cannot prove it. Someone very knowledgeable in computer security within my vicinity. It compromises the safety feature of the car while driving and even backing up in my garage.”
NHTSA complaint #11176202, filed 2019-02, 7,100 miles“Went to start my car and battery was dead. Got a jump from aaa but since none of the eyesight safety features worked, I had the car towed to Subaru and they replaced the battery. I was told I'd need to drive it every day to keep the battery charged. That's absurd. To make things worse, remote start will only work for 2 starts. On the 3rd start, it won't start unless you start the car manually. What's the point of having a remote start if you have to start the car manually every 3 days?”
NHTSA complaint #11416714, filed 2021-05, 2,909 miles“While getting a 2 hr dental procedure, there was an unexplained battery drain, leaving the car dead. I paid aaa to give me a roadside emergency jump. I had had no previous issues.”
