Subaru Halts Sales Of WRX, Legacy And Forester Due To Engine Issues
If you were planning on buying a new Subaru WRX, or any other Subaru using the EJ25 for that matter, you might want to hold off on your purchase for a while...
The automaker has received a low number of complaints regarding big-end bearing failure on a small number of brand-new WRX's and has directed dealers to halt all sales until the cause is pinpointed and a remedy, if necessary, is found. The problem only affects turbocharged models using the EJ25, which means that all brand-new Forester XTs, Impreza WRXs and WRX STIs, and Liberty/Legacy GTs built since early January will be affected by the hold up.
Given the low number of actual bearing failures (less than 10), some might see the sales stoppage as an extreme reaction by Subaru. We're glad they're playing it safe and doing the right thing by the customer, and although they're shooting themselves in the foot sales-wise it's a move that should hopefully increase buyer confidence in the brand for the long-term.
