I believe I am in a catch-22 with my 2012 Hyundai Elantra. I have filed a Lemon Law complaint and Hyundai has just finished its “final repair.’’ According to the company, my car is operating as designed. Hyundai advertises the Elantra as getting 29 miles per gallon. I complained of getting 16 to 18 miles per gallon with mine. Their analysis, however, indicated that it was getting 15.3 miles per gallon.
