What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
None of our seatbelts locked. Only the two seats that no one was in locked. Also, my headrest completely broke off. Our car was later determined by the insurance to be totaled.
I wasn’t close enough to stop it and it rolled down a neighbor of my clients driveway and eventually rolled over landing against a tree. When I arrived at my car it was still running. I have awd and I noticed the tires in the air were not turning as they should have if it was in drive. My car was obviously totaled.
I had almost no time to react, and neither the Automatic Emergency Braking system nor the Forward Collision Warning system engaged. Both of these systems should have activated to prevent the collision and/or minimize injuries and damage. I subsequently collided (harshly) with the aforementioned sedan.
I was driving my 2021 Subaru Crosstrek slowly in a parking lot when it unexpectedly accelerated on its own without me pressing the gas pedal. I believe the Crosstrek was now going 40mph. I tried to shut off the engine and brake at the same time but neither one had any effect. I thought maybe I had two options.
The car lurched forward again, then stopped, and I was able to open the door. My leg was broken with a compound fracture and my foot was nearly ripped off. I called for help, 911 was dispatched, and I was rushed to the hospital in an ambulance.
I immediately turn that setting off every time I get into my car because if I pause for too long at a light/stop sign etc.the engine will stall and turn off (without being in park). I have reported this to Subaru on many occasions and they’ve told me to replace the battery, so I did, and nothing changed.
We were lucky that we found it and were able to have it addressed before the brakes failed.
- There were no warning signals prior to either engine failures. The first one being a year ago for head gasket failure that allowed oil to mix with coolant. With the most recent failure the engine ticked briefly after braking to merge for construction, the oil pressure light followed by engine light turned on 5…
