NHTSA complaint #10155385, filed 2006-04, 123,000 miles

“The contact owns a 1999 Subaru Legacy. The contact noticed that the check engine light appeared on the warning panel. The vehicle was taken to the dealer where the contact was informed that the gas cap caused the light to appear on the dashboard. The contact then examined the vehicle while it was turned on and noticed that gasoline was leaking underneath the vehicle. The failure mileage was 169,000 and the current mileage was 172,000.”

NHTSA complaint #10320728, filed 2010-03, 169,000 miles

“Fuel warning light has never worked according to manufacturer's specifications, which is with 2.5 gallons remaining in the tank. Typically, mine only comes on with less than 1 gallon remaining, and even then usually only after I've stopped the car and then restarted. The dealer replaced the fuel pump, but the problem remained. I contacted Subaru national customer support and after consulting with their tech support personnel (atlanta?), I got a lot of double talk about not being able to control factors involved in my testing (I.e., repeated documentation). …”
