Body problem #1

Welds on bracket that holds clutch and brake pedal to firewall failing. Causing clutch pedal inconsistency along with brake pedal movement upon clutch pedal depression.

Body problem #2

There is a loud squeak noise when the clutch is being pressed, and at times when the structure flexes,it interferes with changing gears. Not only does it interfere with changing gears but,it also causes the break pedal assembly moves when pressing the clutch. I have verified that some weld spot have broken off and have become loose. This is a big problem seeing as how it is a safety issue. When it completely separates, due to shotty welding, not only could the clutch go out while driving but it could cause the breaks to go out as well. This is not wear and tear, I've only had the car for about a 1. 5 years. Welds should not bust that quickly. I have verified in the Subaru community that this is a common problem manual transmission imprezas.

Body problem #3

Firewall spot welds broke, resulting in movement of the brake pedal assembly and clutch assembly. This is causing the clutch to not disengage fully and also making it very difficult to shift due to the flex. As this has the potential to be dangerous and is most definitely a manufacturing defect, it should be subject to a recall.

Body problem #4

My clutch pedal began clicking and creaking this summer. I finally found out that the welds that held the clutch to the firewall were broken. The clutch bracket has only a couple of spot welds that attach it to the firewall, and the firewall is very flimsy. The welds tore away and allowed the firewall, clutch assembly,. Brake assembly, and dash to move and shift whenever I clutched in, causing premature clutch failure and a very dangerous driving condition. This has happened to many gr/gv chassis. This is a known issue and Subaru needs to institute a recall about this dangerous issue.

Body problem #5

Broken firewall welds/clutch squeak im having loud creaking noise with depression of clutch pedal over last few years which did not respond to lithiumgrease lubrication at pivot bolt whereclutch pedal hinges on bracket attached to firewall. According to my mechanic (Subaru certified) there is a failure of a weld on the firewall next to clutch bracket causing a bowing outward of a portion of the firewall and consequentially a loud creaking noise.

Body problem #6

Broken spot welds on rear hatch opening.
