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.
Heat shield was loose and therefore making a loud rattle. Mechanic clamped it down.
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!
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.
strange whirring noise right after cold start up.
ENGINE CONTINUES TO MAKE VALVE NOISE ON START UP FOR ABOUT 5 SECONDS IT USED TO ONLY DO IT WHEN THE ENGINE WAS COLD AND HAD SAT FOR SEVERAL HOURS IT NOW DOES IT AFTER A FEW MINUTES EVEN WHEN WARM
engine making valve noise at start up.
Muffler hanger was corroded
Noise during acceleration. Replaced exhaust valve under TSB.
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
