2002 Nissan Altima 2.5 from North America
The Altima is great for comfort and ride, but inferior in dependability because of engine issues
This car was great until the 80000 mile mark, and then it started running rough at start-up. I noticed that the coolant levels were going down slowly.
I took it to the dealership and complained about the rough start issue, but they pronounced the car to be in great shape. I took it to 3 other mechanics and all said the car was running OK. One mechanic did replace the plugs, and it helped, but soon it started running rough again.
Would you buy another car from this manufacturer? No

Hmmm... you are losing coolant and running rough? If you can't see the leak then you are probably going to have head or head gasket problems.

Altima 2002. 115,000 miles. I also have the same problem. Losing coolant but no visible external leaks from radiator, hoses and water pump. Brought it for pressure test and did not find any leak. I replace coolant about 1/4 gallon every week. Noted that when it temperature goes up radiator fluid level is low. Mechanic's diagnosis is head gasket needs to be replaced. Estimated cost $1500.00 2 weeks in the shop. Mechanic showed me why he thinks that is the cause. He got the device that is meant for emission test that is inserted in the tailpipe. Took the radiator cap and place the device above the filler cap and somebody rev-ed the engine and reading went up. He said HC from the engine is going to the radiator. I did not believe him, because if there is gas coming from the engine and through the coolant there should be bubbles, but there was none. Radiator fluid is clean. I bought a new radiator cap from the Nissan dealer for $26.00 and now I am not losing coolant from the radiator.
$1500.00 problem fixed by a new $26.00 radiator cap.
