148-horsepower 1.8L I4 6-speed shiftable automatic FWD

26000 mi   Though the battery was weak and replaced a few days ago, the car did not start. In fact, it was fully powered, just would not react to the key being turned. I was able to get it started after about 15 tries. The dealer found nothing wrong! 
38250   Added Exhaust Heat Shield Brackets while noticing rattle while driving when cold. 
27900   Noise during acceleration. Replaced exhaust valve under TSB. 
42000   Muffler hanger was corroded

16120   engine making valve noise at start up. 
1000   Having problems starting the car, but only when left sitting for about 2 hrs. Never had a problem with a cold start or a hot start the dealer was stumped but ultimatly replaced the fuel pump hoping that would solve the problem. 
14000   Heat shield was loose and therefore making a loud rattle. Mechanic clamped it down. 
14000   The fuel consumption is TERRIBLE.. less than 20.2 in mixed motoring. I got an Altima whilst the Elantra was in for a bodywork repair and achieved 27.8 doing the same route in the same conditions! The claimed mileage figures are a farce.. too many fellow o 
20000   Car was in for normal maintenance, but I had requested that the rough idle be examined. The ended up replacing the head gasket. This improved mpg but did not solve the rough idle. Car had a rough idle. A week after the prior visit (oil change, with them also replacing the head gasket), I took it back in but they could not reproduce the problem.
