So my buddy had a 2003 Nissan Altima 2.5 S, right? It was decent for a few years but then started acting up. The check engine light came on a bunch, but he ignored it. That was a mistake. Turns out, the O2 sensors were fried, needed replacing. Another thing, the AC stopped blowing cold air. Pretty annoying in summer, I tell ya.
He also had issues with the water pump. It started leaking and caused some overheating troubles. He had to swap it out. But maybe you’ll be luckier. Engine mounts can go bad too, makes the car feel shaky and noisy when you drive. Anyone else had problems with the spark plugs? His wife complained about the spark plugs because it felt like the car hesitated a lot.
The brakes also needed attention. He had to replace pads and rotors. Also, the fuel pump was acting weird, ran out of gas on him a couple times. Driving those old engines, sometimes you think they’re falling apart, hah. How’s your ride, had anything like this happen?
I’ve got a 2003 Nissan Altima 2.5 S up here in Canada, and it’s a solid ride, but man, those seats can be a pain—started squeaking after a year. Fuel pump issues are a common headache, mine went on me around 80k miles. You gotta stay on top of the timing belt, it’s a nightmare if it fails. Apart from that, it drives okay, but yeah, peeps do mention slow acceleration. Always a trade-off!
In Toronto, I’ve had tons of drama with the AC—keeps freezing up. Also, the engine’s timing belt screams as if something’s always gritty. Some part of a 2003 Altima 's charm, right? Always dealing with some whining from under the hood.
I’ve got a '03 Nissan Altima 2.5 S up here in Canada. The brakes and AC were a nightmare—had to replace both within 5 years. Oil leak under the valve cover too; constant trouble with that. But otherwise, drivin’to bad for daily commute. Anyone else? 
I’ve had my '03 Altima out in Texas, lots of stuff pops up. Fuel pump gives out weird after 100k miles; had to replace the A/C compressor too. My buddy up in Canada felt the same with his 
But otherwise, rides smooth if you maintain it.

Gotta bit of luck, and it’s a steady ride; just watch those fluid levels!
