I own a Nissan Sentra 2004 1.8. car currently has 48,7000 miles, on Feb 2010 check engine light came on, I checked ang gave me a code that said random misfire, then I replaced spark plugs and I notice #2 was a little bit different from the others, so I replaced the coil too on #2.car was kind a shaking when starting the car for about 5 to 8 seconds and then would run fine.I clear the code and stayed off for a few days and come back on for another few days, after 3 or 5 months when off for almost 6 months and then came back again, I replaced spark plug #2 and found some antifreeze smell on the bad spark plug I pulled out, car still does the same but now I noticed I loosing antifreeze, but there is no external leaks, talking to the dealer they said is common on this cars with this mileage to have this problem and have the head gasket replaced to fix the problem, but I don, T agreed, it has to be some kind a the problem because many people having problems with the same car. If I want to buy another car I am very sure it won, T be a Nissan because they do not accept responsibility for what the built. 06/29/2011 kirkland wa.

My 2004 Nissan Sentra engine would cut off while driving at various speeds. This would cause me to almost get into a crash on the highway. Mine is a 1.8 liter engine, and the recall was for the 2.5 liter engine, and just as many 1.8's have been having this problem. Had to pay $200 out of pocket to fix this. Then after I get the car fixed, the check engine light will not come off, and the mechanic says, no code is coming up for anything. I am scared to death to drive my car.

My 2004 Nissan Sentra 1.8 has been towed 3 times in the past 6 months. It has a blown head gasket. This is apparently a manufacturer's defect as I have seen 30 complaints with the same problem.
