The 2004 Nissan Titan is a full-size pickup truck and the first model year of Nissan’s original Titan generation, introduced to compete directly with domestic half-ton trucks. It’s ideal for drivers who want strong V8 power, a roomy cabin, and real towing capability without stepping up to a heavy-duty platform. As a debut-year redesign, it brought bold styling and a big interior, but it also arrived with some early-production quirks that show up in 2004 Nissan Titan reliability and owner reports. Shoppers comparing 2004 Nissan Titan problems and 2004 Nissan Titan common issues should focus on drivetrain behavior, rear axle history, and overall maintenance records.

1) 5.6L Endurance V8: The 2004 Titan launched with a 5.6-liter V8 (305 hp, 379 lb-ft) paired to a 5-speed automatic transmission, delivering strong acceleration and confident passing power for a full-size truck. 2) Rear-wheel drive or 4WD: Available RWD and shift-on-the-fly 4WD configurations (trim-dependent) make it a practical choice for both daily driving and light off-road or winter use. 3) Full-size towing and hauling capability: When properly equipped, the Titan is known for solid towing numbers for its era, plus a useful bed and payload capacity for work and recreation. 4) Spacious cabin design: Crew Cab models in particular are valued for generous rear-seat space, making the Titan a family-friendly pickup for road trips and daily commuting. 5) Strong value in the used market: Many buyers cross-shop it against early-2000s F-150, Silverado, and Ram trucks, often finding the Titan offers a lot of V8 performance per dollar.

When researching 2004 Nissan Titan reliability, it’s important to remember this is the first production year, so complaints tend to cluster around a few repeated themes. Here are several 2004 Nissan Titan common issues that show up in owner reports and service histories: 1) Rear differential and axle seal leaks: One of the more discussed 2004 Nissan Titan problems involves the rear axle/differential area, including leaks at axle seals and noise or vibration from the rear end. Symptoms can include gear oil seepage on the inside of rear wheels, humming/whining that rises with speed, and vibration under load. These issues can appear anywhere from roughly 40,000–100,000 miles depending on use and maintenance. 2) Exhaust manifold cracking/leaks: Some owners report ticking noises on cold start that can indicate an exhaust manifold leak or cracked manifold. This tends to become noticeable as mileage climbs (often 80,000+ miles), and it can lead to exhaust odor, noise, and potential emissions concerns if left unaddressed. 3) Brake wear and rotor warping: Premature brake wear and pulsation under braking are common complaints on early Titans. Warped rotors can cause steering wheel shake during stops, especially after repeated heavy braking or towing. Many trucks experience this by 30,000–60,000 miles depending on driving style and brake component quality. 4) Fuel economy and sensor-related drivability issues: While not always a “failure,” the Titan’s V8 can be thirsty, and some owners encounter check-engine lights tied to oxygen sensors, EVAP components, or related emissions hardware as the truck ages (often 100,000+ miles). These issues can affect MPG and idle quality but are typically manageable with proper diagnosis.
