Selected complaints filed with NHTSA by 2008 Subaru WRX owners, lightly cleaned up (personal details are redacted by NHTSA).
I own a 2008 Subaru impreza WRX with a stock clutch. For approximately 2 years I have been hearing creaking and/or clicking noises when engaging the clutch pedal. Began to look online for a solution and found that there are spot welds that break between the firewall and the mounting bracket the clutch pedal assembly is attached to (https://www.google.com/?gws_rd=ssl#q=WRX+spot+welds). I removed the necessary items to inspect the welds and they did unfortunately fail.

The welds supporting the clutch pedal and brake pedal assembly have broken. The result is a prominent squeaking sound and a noticeable lateral movement of the pedal assembly to the left. This is a reoccurring issue as it had previously been addressed and repaired back in June of 2014. At the time Subaru of America agreed to pay for half of the repairs as the vehicle was outside of warranty coverage. The new issue are from broken welds in another area that was not inspected or did not appear to need repair at the time. Mileage at time of repair was 74,839, current mileage is 84,420 (3/16/2015). However, further research on this issue indicate that it is a widespread issue that has affected many other Subaru impreza owners with model years 2008 through 20012. This is not the result of owner neglect, misuse, or improper maintenance. …
The welds that attach the brake and clutch peddle to the vehicle brake and allow the whole peddle assembly to move. Because of this, braking efficiency and drive gear engagement become compromised. In the event that a hard stop is needed, the whole assembly could brake and keep the driver from being able to stop. This issue is a huge hazard! This is not a convenience issue, this is a life and safety issue to not only the occupants of the Subaru but everyone on the road! I have contacted soa, and they informed me that I would have to take care of the repair myself. This repair is not just some nuts and bolts coming loose or something like that. This is a huge repair that is structural to the vehicle. At costs of well into the thousands! Soa knows of the issue and refuses to do anything about it! …
The part of the steel body under the dash that supports the clutch pedal shaft assembly fractures into two pieces due to flex forces over time. This results in the clutch master cylinder flexing at its mounting point on the firewall when clutch pedal is depressed. Severed squeaking and noise is heard every time the clutch is depressed as a result. Welding is not feasible as it is located un the dash (above the accelerator pedal) and would cause fire around flammable materials. This can be seen on youtube videos submitted by Subaru WRX owners and affects 2008-2014 WRX impreza vehicles. Should firewall fracture due to this flex over time, ability to disengage the clutch by pressing the pedal would result and present a very high probability of crash or accident as a lack of vehicle control and ability to stop vehicle. For one video of this, see: https://www.youtube.com/watch?v=zr6umgz5utc.
Firewall spot welds have failed, causing significant lateral play in the clutch pedal. I have had some significant trouble trying to get it into gear. So I have had trouble shifting gears while at highway speeds and have had trouble getting it in reverse in order to pull out of a parking spot. The brake pedal is next in-line to be affected by the sheet metal tear. I keep hearing that this problem is not covered under any recall. Nor is it a warranty item at this year and mileage (105,000). This is a very significant issue and will cost a great deal (over $1000) to fix. This being a weld issue and not a wear issue makes me think that the factory ought to cover this safety issue. This has been happening for the last year and a half. But I have only recently discovered the true extent of the problem.
I bought this vehicle used from a dealership in January of 2015 with over 100,000 miles on the odometer. After a few months of driving it I began to hear a click every time I depressed the clutch pedal. I looked into the issue to see if it was a common problem and if there was an easy fix to it. Turns out six of the seven spot welds that hold my clutch and brake assembly to the firewall were cracked. There is a recall for this issue already but they wont service vehicles past 40,000 miles.this does not help me seeing as the car is far past 40,000. Not only is this a safety issue but it is also causing other parts of the car to prematurely wear out such as the clutch and the release bearing. I need help.
I purchased a 2008 Subaru impreza WRX. Every time the clutch is engaged or disengaged a creak/pop noise can be heard. You can also see the clutch and brake pedal move significantly. The spot welds on the firewall/bulkhead have separated making it very difficult to get into gear and making the clutch very firm. This needs to be a recall. People can not afford this very expensive while making payments on their vehicle. This problem is also causing premature wear on transmission parts as well. I have 4 subarus and if they don't make this right I will not buy another. Very sad to say considering I work for them building engines.
The clutch pedal was making a lot of noise, progressively getting worse over the years that I've owned this car. I took it to the dealership and they adjusted the pedal assembly. The noise came back shortly after so I took it to the dealership again and they replaced the pedal assembly. Once again, the noise came back, but this time it was worse than ever. The dealership is saying the clutch pedal mount has had all welds fail that attach it to the firewall. Subaru needs to address this as it seems many owners have this same issue.
Clutch started making a creaking noise when pressing in and out. Shifting gears has also become more difficult like the clutch isn't fully engaging and disengaging. I also noticed the whole assembly shifts (clutch and brake pedals) when pressing down on the clutch. Turns out the spot welds on the bracket that hold the assembly are completely broken, causing flex to the clutch and brake assembly. If that bracket rips off, could lose braking power. This is unsafe and needs to be recalled.
A couple years ago my clutch started to creak. I asked the local Subaru dealer to check it when I took it in for a scheduled oil change. I got told they couldn't find a problem. So I thought nothing of it. I just took it back to the dealer and got told the spot welds on the firewall. Subaru offered to fix the welds but I have to pay for a new clutch assembly. If the welds totally fail this could become a serious safety issue as it will affect the brake motion also.
