I have a 2003 Nissan Altima 2.5 SL. Car drives like a beauty most of the times but when i'm driving on the highway at 60-70 mph, I get occasional vibrations in the steering wheel. It's not due to road surface. I have checked. I was told by a mechanic that my rear alignment is off b...

I know this isn't an "important" thing. It just bugs me. It worked then stopped. The remote still locks and unlocks so I know it isn't that. I just have no idea what it could be and I liked the noise to make sure I know the car was locked. The lights still flash and everything, ...

We took it back and they said we needed to replace some valves for another 300 plus dollars. We then took it to Nissan and they told us the ...

The engine coolant temperature can vary at the coolant sensor due to its unique location. If these variations are large enough, a brief interruption in the signal output from the sensor may occur. If the signal interruption is so brief that the electronic control module (ECM) logic does not have time to diagnose the condition, the engine may stop running without warning. This condition will commonly occur only at low speeds. If the engine stalls without warning, a crash may result. Dealers will reprogram the ECM to correct this concern. The Nissan recall number is R0606.

Nissan is recalling 2002-2003 Altimas in cold-weather states because in extremely cold temperatures, moisture in the fuel tank could freeze and form ice crystals, which may obstruct the suction opening of the fuel pump. This can prevent the supply of fuel to the engine and cause the engine to stop, which could result in a crash. Dealers will install a screen at the suction opening of the fuel pump.

Nissan is a lousy company when it comes to treatment of its customers and build of their product.

2003 Altima 3.5L SE V6 - catalytic converter went out at about 100K and got sucked up into engine resulting in later engine failure. Cost $7K to replace engine. This is common with the 2.5 4-banger so what happened to me? Also, before engine began to fail I had a rattling noise in the engine which turned out to be the timing belt tensioner. I wasted $2K getting this repaired on what later becam...

This car has worked amazingly well with minimal maintenance and I just love my car. The only thing is that the car gets between 20-24 miles to the gallon.
