What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The airbags did not deploy. The car and the building received extensive damage.
Both headlights going out at the same time. This has happened about ten times over the last four years and now I have no headlights. I have tried three different headlights in the last month, the first two worked briefly and the last one from subaru did not work at all.
What is the issue? Basically the firewall is so thin that it flexes terribly every time the clutch or brake pedal is pressed. The big problem is the way the clutch/brake assembly is secured to the thin firewall. It only has 6 small spot welds that rip off the firewall after time.
We have not heard from the dealer about replacing the air bag we had an email in july 2016 called to make an appointment and they said they did not have the part in thats what they were waiting for this is october 2016 and we have not heard anything yet.
Broken firewall welds/clutch squeak im having loud creaking noise with depression of clutchpedalover last few years which did not respond tolithiumgreaselubricationat pivot bolt whereclutch pedalhingeson bracket attached to firewall.
The clutch bracket on the firewall has only 4 small tack welds from the factory. This bracket takes all the force of your leg pushing in the clutch every time you change a gear.
