Blew 3 valve gaskets within two weeks after buying car. Blew 2 tires within 2 months of having the car. They �fixed� an oil control valve and then it needed another. Sway bar links needed replaced, cv joints need replaced, brake pads are extremely low. Ac doesn't work. Had to buy all new tires.
The fire wall broke and the pistons had nothing but problems then it blew the crank.
Vehicle was not stationary, it was being tuned and the fire wall got to hot and started to smoke. In addition the third cylinder in the motor went bad as well and the motor was replaced due to a rod knock and the 3rd cylinder going bad. The vehicle has 80000 miles on the vehicle.
My clutch bracket broke on the welds. This is an oem product that has a defect and it is well known on the internet and forums. Subaru of newton NJ refuses to fix the problem and was well aware. This was very dangerous for me since it happened on a highway at speeds of 65 mph. The bracket is broken and the clutch will not engage. I have noticed the firewall is cracking also. The brake pedal moves inches to the side when the clutch is pressed. This is a very dangerous problem. I am very disappointed with Subaru and the car only has 73k miles on it. I also filled with Subaru and I am awaiting answers.
A loud squeak is occurring when I press and release my clutch. I had my clutch replaced about 10k miles ago due to a seized throwout bearing. I brought it to the dealer, they lubed it all up but squeak is still there. The tech said the noise is actually coming from the bracket that is mounted to the firewall under the dash. After a few hours of research, I have found numerous posts about this issue and it lies with the welds holding the bracket being faulty and breaking. This causes the firewall to flex and your whole pedal assembly, clutch and brake, to move around while in operation.
Car began 'stumbling' at 3k rpm under very light load/throttle. Had substantially less power at highway speeds. Small trace of white smoke during startup, only happened once. Compression/leakdown results; cyl1 = 115 / 10%, cyl2 = 125 / 10%, cyl3 = 117 / 18%, cyl4 = 100 / 23%. Driving habits are mild, I-mode 90% of the time, shifting at 2800-3200 rpm. . . Car is currently at dealer, they have confirmed an issue and we're awaiting response from Subaru of America on whether or not this will be warrantied.
For at least 20,000 miles now (I'm at 55,000) I have had a very stiff clutch pedal and terrible squeak with every depression of the clutch. My clutch is slipping in 3rd, 4th and 5th. This was reported and diagnosed under warranty around 30,000 miles by the pembroke pines Subaru dealership. Subaru of America requested that the pressure plate and possibly the clutch be replaced (ignoring my statement that the tack welds holding the clutch assembly in place were snapped -- which they are, effecting engagement and likely damaging the clutch/pp/flywheel). After moving to asheville, nc right at the time of soa making this request, the Subaru dealership (prestige) refused to honor soa's request stating they were a franchise dealership and did not have to listen. I expect the pressure plate & clutch, along with the firewall welds, to be repaired under soa warranty.
I own a 2008 Subaru Impreza sti which I purchased in Feb. Of 08'. 2 months ago the car went into limp mode when I was driving home. I took it to the dealership to have it checked and they said it only had 1 1/2 quarts of oil in it. I had checked the oil the previous week and it had shown full. They requested that I give them record of my previous oil change so I did. Unfortunately, it did not have mileage documented because it was a small shop that did it for me. They refused my claim on the grounds that I did not maintain the car. They then sent me a re-call form in which it stated that the ecu was causing the car to run dangerously lean and was causing ring failures. I told my lawyer about this and sent him a copy of the letter. When he called the dealership, they told him that they were unable to make any repairs necessary and that it was my issue.
The contact owns a 2008 Subaru Impreza. While driving between 5-10 mph and depressing the brake pedal, the engine revved up to 2,500 rpm's. The failure occurred soon after the vehicle was purchased. The vehicle has been taken to the dealer three times for this failure. It has since improved, but the engine still revs from 1,500 to 2,000 rpm's. The contact is concerned that the failure will worsen in the winter. She filed case number 1121875 with Subaru. The current mileage was 1,107 and failure mileage was 400. Updated 07/17/08.
