Subaru Issues Temporary Stop Sale on Vehicles Equipped w/ 2.5L Turbo Engine
Subaru of America has issued a stop sale on all models equipped with the company's 2.5L turbocharged four-cylinder engine. The stop sale — which affects Forester, Legacy and Impreza vehicles equipped with the engine built in January and February — is due to a potential engine wear issue.

According to the stop sale order issued to all U.S. Subaru dealers, in markets outside of the U.S., Subaru has received complaints of an engine knock in vehicles equipped with the 2.5L turbo engine. After investigating, Subaru determined that the engine noise was due to engine wear and has since discovered which batches of vehicles are at risk of being equipped with the faulty component.

No U.S. models have been reported to have the problem, but Subaru wants to ensure it's not selling its customers faulty vehicles.

The defect is said not to impact vehicles with the naturally aspirated version of the 2.5L or any other displacement engines.

 

Best to nip it in the bud...

 

Strange, considering the turbo 2.5L engine has always been pretty reliable.

 

Surprising that this has happened, but glad they did! Wise move on their end.

 

They made some revisions to it this year.....I don't remember the details.

 

Well, I'm not an engineer, but, since the knock only seems to affect non-U.S cars, it makes you wonder if it is just crappy gas causing spark knock, and not an engine defect or wear issue. Canada is generally OK, but Mexico is notorious for poor-grade gasoline.

If it IS a faulty engine component like the article says, then my guess would be a knock-sensor.....most turbo engines have them.

 

More low end torque.
