Engine & cooling

AT 26,469 miles the harmonic balancer separated into two pieces while driving causing sudden loss of power steering. I contacted Subaru for assistance with this know problem.

I have been a Master ASE mechanic for over 25 years at a dealership and know repairs of this type are usually done in house under a goodwill policy, otherwise swept under the rug so there is no recall. I went to the local dealer here and the tech there said he use to do the repair almost everyday. the same thing...

happened to my housemates at some time and he doesn't remember the details. This is a serious problem and there should be a recall as it could result in death given the circumstances the driver is driving in.

My mechanic stated it would cost around $1200.00 To fix. The car has 161k miles and is still in good condition. Can you advise if subaru ever recalled this car due to faulty header gaskets ?

When braking for a stop light or stop sign the engine continues to race and stopping forward movement requires applying hand brake and sometimes turning off engine. First reported in 2006 there have been two incidents in the past several weeks (june 20 to july 2, 2014) each involving a different driver. Floor mats had been removed following the earlier incidents in 2006. In each of the prior incidents rearing ending of the auto in front was narrowly avoided. Mileage on the vehicle is currently is 82,800. Updated 2/18/15*js

There is a fuel smell under the hood. A repairman said that the fuel clamps were loose, however, to get to them he had to take the fuel rail off the motor to e to the clamps. They could not be serviced without dis assembly. We were quoted $500 to make the repair. This problem is prevalent on web chat rooms for these cars. *Tr

etc without drive belts. It was further found and noted that the pulley mounted on the end of the crankshaft had in fact separated from its mounting hub and was easily removed by hand without effort. The slipping loose and wandering pulley resulted in throwing and damaging the power drive belts and could have come off completely and be propelled into the radiator and other components. Being able to pull off the road immediately and shutting off the engine prevented further danger and damage. *Tr
