  • 80,000 miles


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.

Oil leaking from premature head gasket failure. Oil leaking on a hot engine can cause a fire. This is common for this make, model and year, due to incorrect sizing of the gasket. It is defective from the factory and may result in a fire.

Head gasket prematurely leaking oil. Leak finds itself near exhaust. A little bit of research finds that this problem is very common up until 2010 and the introduction of the newest engine. An improved gasket is available, but replacement is very expensive. This is clearly a defective part and the affected cars should be recalled.

The head gasket is leaking. This will cost over $2000 to fix. This should not be occurring.

According to the dealership the catalytic converter in my 2008 Subaru Impreza has prematurely failed. The vehicles check engine light came on and the car went into "limp" mode while driving, in conjunction with the check engine light my vehicle has been experiencing very poor gas mileage for the last month. The dealership has quoted me over $2000 for the repair of my car. It was brought to my attention that several other same model year Subaru's have recalls due to the catalytic converter not performing to emission standards. Some of these cars have the exact catalytic converter part number as my car, I do not understand why car would not be recalled also.

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.

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.

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.
