This problem first started in November 2013 when the car had 93,000 miles. The check engine light goes on and the cruise control stops working and the code is for a vacuum leak. I've had 4 different mechanics address this issue. One put in an ignition coil, which was replaced by another one who said the first one must have been defective because no other cause could be detected after a lot of time spent trying to diagnose the problem. I've replaced the gas cap 3 times (twice with official Subaru gas caps) and finally, the catalytic converter replaced. I was able to travel from New Mexico to Missouri the last time before the check engine light went on again, a record number of miles! It's SO annoying to travel across the country without cruise control!

Check engine light and "flashing" cruise light still on after several diagnostics checks and new gas cap (from dealer). Discern NO leaks yet light comes back on w/o warning while driving after every one to date that has been "cleared" by dealer/local shop. This is the same complaint as two others on your site and I wonder why Subaru is not addressing.

Update from Aug 25, 2013: After visiting your site and seeing this is a common problem, I contacted the dealer and at their suggestion called Subaru directly. Subaru agreed to cover half the repair cost, so I have resolved the problem at present. Thanks for your site.
