Failure Date: 02/01/2017

Manual transmission 2008 Subaru Impreza wrx, have trouble switching gears, and specifically putting vehicle in reverse from a cold start. For a while heard a popping noise when pushing the clutch down. But switching gears is very difficult/clunky and placing the vehicle in reverse from a cold start is extremely difficult. After doing research this appears to be related to Subaru bulletin 12-184-15 (an issue with welds on the firewall). The brackets/welds on the firewall seem to be breaking/are broken.

Failure Date: 08/05/2016

On three separate occasions (April 10, 2016, June 13, 2016 and August 5, 2016),suddenly and without warning, the car stopped responding to gas pedal input, stopped running, and coasted to a stop. The engine would continue to run, but the car would not move. Fortunately the incidents occurred while on city streets, and not on the freeway. Had I been on the freeway, I would have been rear ended. That would have had tragic, perhaps fatal consequences. The car is currently at the dealer's for repair after the third and latest incident. I had taken it to the dealer's after each of the other incidents as well.

Failure Date: 07/05/2016

I had just turned and pushed on the gas to get up to speed-about 45mph. The car would not stop accelerating/revving. I was heading to a light turning red. I pushed on the brake as hard as I could and also but on the emergency break. Between the two, I overcame the acceleration. Once stopped, I put the car into neutral and then into park. At that point the acceleration finally stopped and the car seemed to reset itself. I took it in to be looked at-it had never done that before-very scary. I have heard of this problem with Toyota's, but never Subarus.

Failure Date: 04/17/2016

I was driving on the highway and I was accelerating to pass someone when all of a sudden my car revved up very high and accelerated very fast to an unintended speed. I braked with no effect. I put all my weight on the brake, almost standing up, for about 10 seconds, then I heard a loud snap under the car, like I just unstuck something, then it revved back down to a controllable speed. If it wasnt for the fact it was early morning and there weren't as many cars around me on this highway I would have surely been hit or hit somebody else. Very scary. Luckily, I didn't, and my car's been driving okay for past few days ; it is at the dealership as I write this (4/21/16) getting checked out.

Failure Date: 11/05/2015

About 6-8 months ago as I was making a turn I pressed the brake pedal and instead of slowing down the engine throttled up. And after a few moments went back to normal. Two weeks ago as I pressed the brake pedal while coming to a stop sign the engine throttled up and I had difficulty coming to a stop. I put the car in park and turned it off. When I started it again the engine immediately went to high throttle to the point that the front of the car started vibrating. I turned it off again and restarted it and this time it was ok. I took the car into the Subaru dealership. Their mechanic ran the diagnostics and was unable to pin point the problem. They decided to call the Subaru technical department and were told to not let me drive the car until their engineer took a look at the problem. This was a week ago and I have not been able to find out what they have found.

While on the brake pedal, the vehicle accelerated. This happened on two separate occasions; both while my foot was on the brake pedal. The first time this happened, I was on my brake at a red light (stationary) and the second time, after I went over a small "lip" on the asphalt, I was braking to park in front of a house when it accelerated substantially, causing extensive damage to the house and car, while almost killing me.

Subaru eyesight will lock up brakes when actively being engaged and the car in front of you makes 90 degree right turn as if the car was still in front of you and you were about to crash into it. But it isn't there instead you will be crashed into from the rear. It will do this every time guaranteed. Just set following distance to 1. 1 sec get behind a car doing over 25 mph and enjoy. Dealership insists that how it suppose to work. If this was Subaru's intend in any way it needs to be corrected. Hitting gas pedal won't help it will only rev up the engine but car keeps braking.

Failure Date: 12/22/2014

The fire wall is cracked and the welds are broken which is causing my clutch to not disengage properly and the clutch pedal to not function correctly.

Failure Date: 04/20/2014

My car started making this really loud popping noise everytime I would engage the clutch. What has happened in the past when I press on the brake pedal my foot has shifted off the pedal due to a fast sudden move from the clutch and brake assembly. I drove the car to texas to visit family and decided to take the car for oil change before returning to California. There the service manager at Subaru in texas, which drove my car to the service area, asked me if I had noticed the clicking noise and I told him yes. He then informed me that many 2008-2009 Impreza wrx have problems with weld spots which hold the brake and clutch assembly to the fire wall that then fail and brake off. He gave advice on how to look for broken welds, so as soon as I arrived to California I further inspected for the broken welds and sure enough he was right. So I contacted Subaru of America and described the defect on my car to have them repair it since it's a safety defect, specially with critical components of the car which are the clutch and brake pedal. As of today 11/5/2014 they have yet to decide if they are covering the repairs because my car is currently 85k and its no longer under warranty. Also, they are blaming the clutch because it has been replaced prior to me purchasing the car with an oem replacement clutch. I have never experinced such a nightmare with any vehicle that I have ever owned. I really hope NHTSA does something before any fatalities or accidents accur. I am currently going threw this right now, so I have yet to find out what they are going to do with my car. I really need help from NHTSA, even if they fix my car, Subaru needs to notify owners of this year and models of this problem. All over the internet there are people with the same issue and others that are yet to go threw. Owners need to be aware and cautious about this important fabrication defect.

Failure Date: 02/02/2014

The clutch pedal on my 2011 sti makes a loud creaking noise every time it's depressed. When I investigated the noise, I noticed that the entire clutch pedal bracket assembly (attached to the forward firewall) shifts approx 1/4 inch every time the clutch pedal is depressed. I found that the three spot welds securing the clutch pedal bracket to the forward firewall were broken. From the outside of the firewall, just under the windshield wipers, I saw the spot welds pulling away from the firewall every time the clutch pedal was depressed. This allows the entire clutch pedal bracket assembly to move, causing the creaking noise. If the bracket completely separates from the firewall, the clutch may become completely inoperative - especially dangerous while driving. This has also directly caused the failure of three clutch master cylinders in the last 6 months. 2 of which failed at freeway speeds leaving me with no clutch, and a hardly any braking capability. (the clutch and brake pedal are both attached to the same assembly, thus when the clutch does not work, neither do the brakes.

Failure Date: 01/05/2014

While driving in normal circumstances, engine power cut out, and complete loss of throttle control occurred. The car could only accelerate extremely slowly, and not past 20-25 mph. Thankfully not on a high-speed road. Managed to get home (barely), car worked fine the next day. Dealer found obd code p0128, reprogrammed ecm to remove the code. The same problem had occurred ~1 year previously due to a faulty accelerator position sensor (NHTSA complaint recently filed). Dealer claims causes are unrelated. This can be a serious safety concern if it occurs on a highway, we no longer feel safe driving this car.

Failure Date: 08/02/2013

Driving about 30 - 35mph when all of a sudden the car lost power. The car did not stall, but engine went down to idle speed and my accelerator pedal had no throttle control. The "check engine " light came on as well as the "traction control" light. I drifted to the right shoulder of the road and turned engine off. After opening the hood to check engine - observed nothing unusual - I re-started the car. The car seemed back to normal, but the engine code lights stayed on. The warning lights eventually turned themselves off - 3 or 4 re-starts later. Subaru dealer reported a p2138 obd code, but he did not replace/repair anything. The same exact thing happened 9 months later (July 2, 2014), and Subaru dealer reported a p2138 code once again. No repairs or replacements done!.

We were pulling into a parking place, turning the wheel and the car unexpected leaped forward. This has occurred now 5 times--all times moving slowly forward, turning the wheel as we tried to park. This has occurred with both my partner driving, and with myself driving. So far we have managed to slam on the brakes in time--and they stopped the car. But we fear crashing or accidentally hurting someone.

Failure Date: 09/24/2012

The bracket that attaches the clutch and brake pedals to the inside firewall has separated from its spot welds and is causing a loud creaking noise, as well as difficulty with shifting gears, and decreased braking ability. Very dangerous situation as it affects your ability to control the vehicle properly.

Failure Date: 09/12/2012

While driving in normal circumstances, engine power was lost, and complete loss of throttle control occurred. Car would accelerate extremely slowly, and not past 20-25 mph (presumably 'engine fail-safe mode'?). Thankfully not on a high-speed road. Obd code was p2138, indicating a faulty accelerator position sensor, which was replaced by dealer under warranty.

Failure Date: 03/12/2012

The spot welds holding the clutch, brake and gas pedal assembly to the firewall failed entirely, allowing the pedal assembly to become detached from the vehicle and move toward the firewall with any pedal action. I was no longer able to disengage the clutch and the brakes delivered inconsistent performance.

Failure Date: 01/08/2012

The contact owns a 2008 Subaru Impreza. The contact stated that while exiting a drive-thru, the vehicles exhibited a loud bang and the vehicle immediately accelerated abnormally. The contact attempted to apply the brakes, but there was no response causing the contact to crash into a tree. The contact was severely injured and was taken to the hospital. The vehicle was destroyed. The contact was told that the throttle had erroneously opened fully and would not close, causing the vehicle to accelerate abnormally. The failure and the current mileages were 20,000.

Failure Date: 12/01/2011

Vehicle started with a noise in the clutch pedal. Went away with lubricant. Then began to make a clicking sound and the clutch and brake both started to move as I depressed the clutch . The shifting of gears became difficult from the start of reverse or first gear. Then it be came real loose I had a mechanic look into it and mentioned that a weld has broken and did not recommend him fix but to have the dealer take a look at it because its a safety issue and if it breaks completely that it may cause the car to be unable to stop . So I took it to the dealer and mentioned it was out of warranty. But they will look at it. Currently they mentioned they cannot fix it under warranty so currently I cannot afford to get it resolved so im unable to drive the car.
