Purchased vehicle in south carolina and drove it back to northern kentucky. It produced approximately 380 miles on one tank of fuel. Note: it was well into the 50-60 f range outside while driving during that time. Subsequent fill-ups in northern kentucky (with outside temperatures ranging from 10-30 f) produced 160-225 miles in-town. I experienced a very strong, raw fuel odor in the passenger cabin. It was taken to a mechanic and they found "nothing wrong. " this of course, does not mean there is nothing wrong. The fuel lines were checked and tightened even though they were neither loose nor worn. After reading the numerous complaints about this problem from other owners, it seems that Subaru owes me and many others a recall. Today is about 14 f outside and I drove the Subaru 16 miles. The fumes were so unbearable I had to pull over and wait for them to subside. This seems like not only an emissions violation, but also a fire and health hazard.
