Years

The Nissan Frontier is a mid-size pickup truck that has served as Nissan's primary truck offering since the full-size Titan was discontinued after 2024. It debuted in 1997 as a replacement for the Hardbody, with a second generation arriving in 2005 and a substantially revised third generation launching for 2022. Built on a body-on-frame platform, the Frontier is typically noted for its available four-wheel drive, Pro-4X off-road trim, and towing capacity of roughly 6,700 pounds.

• 
  2001

  The 2001 Nissan Frontier continued on the D22 platform with minor updates, including a revised grille, and offered 2.4-liter four-cylinder and 3.3-liter V6 engines in King Cab and Crew Cab configurations, with a supercharged V6 available on select trims. Common service considerations include timing belt replacement on both engines, inspection for frame and body rust, and monitoring of rear axle bearings and suspension components such as ball joints. The automatic transmission in some examples has been known to develop wear, so fluid condition and shifting behavior are worth checking.

• 
  2003_Frontier

  The 2003 Nissan Frontier was largely a carryover year for the second-generation D22 platform, with only minor trim and equipment updates. Engine choices included a 2.4-liter four-cylinder and a 3.3-liter V6, with a supercharged V6 offered on SC trims. Common service considerations include timing belt replacement on the V6, inspection for frame and body rust, and attention to the automatic transmission and rear axle components on higher-mileage examples.

• 
  2005_Frontier

  The 2005 Frontier was fully redesigned on a new body-on-frame platform, offering a 4.0-liter V6 or a 2.5-liter four-cylinder engine paired with a 5-speed automatic or 6-speed manual transmission. King Cab and Crew Cab configurations were available, along with an off-road-oriented PRO-4X trim. Common service items include cooling system and radiator checks, transmission fluid maintenance, and timing chain system inspection. Frame and undercarriage rust prevention is worth attention in regions that use road salt.

• 
  2008_Frontier

  The 2008 Nissan Frontier continued the D40 generation with the 4.0-liter V6 (261 hp) and an available 2.5-liter four-cylinder, with minor trim and equipment revisions for the model year. Common service considerations include monitoring the radiator for plastic end-tank cracks, which can cause coolant leaks and overheating. The V6's timing chain system should be inspected for tensioner wear, and regular transmission and rear differential fluid changes are recommended. Periodic transfer case fluid service is also advised for four-wheel-drive models.

• 
  2004

  The 2004 Nissan Frontier was the final year of the second-generation D22 platform, with few changes from the prior model year. It was offered with a 2.4-liter four-cylinder or a 3.3-liter V6, the latter available in a supercharged version on select trims. Common service considerations include timing belt replacement on the V6 at the manufacturer's recommended interval, frame rust inspection in regions that use road salt, and routine maintenance of the transfer case and front hubs on four-wheel-drive models.

• 
  2007_Frontier

  The 2007 Frontier was largely a carryover from the 2005 redesign, with only minor trim and equipment updates. The available 4.0L V6 is generally durable, but radiator failures from cracked plastic end tanks are a common issue that can lead to overheating if not addressed. Some V6 engines also exhibit timing chain rattle on cold starts, and the automatic transmission benefits from regular fluid service. Inspecting the rear differential pinion seal for leaks is another commonly recommended check.

• 
  2009_Frontier

  The 2009 Nissan Frontier was largely a carryover model, retaining the 261-horsepower 4.0-liter V6 and the 2.5-liter four-cylinder on select two-wheel-drive King Cab trims, with only minor equipment and trim updates. Common service considerations include checking the automatic transmission fluid for coolant contamination, a problem linked to radiator failures in earlier D40 models, as well as inspecting the rear leaf springs, wheel bearings, and timing chain system. Frame and underbody rust inspection is also worthwhile in regions that use road salt.

• 
  2006_Frontier

  The 2006 Frontier was largely a carryover from the redesigned 2005 model year, with minor trim and feature adjustments rather than mechanical changes. It was offered in King Cab and Crew Cab configurations with a 2.5-liter four-cylinder or a 4.0-liter V6 paired with a five-speed manual or five-speed automatic transmission. Common service considerations include regular transmission fluid changes, as the automatic's cooler is integrated into the radiator, making radiator failures a known concern that can contaminate the transmission. Owners also commonly address timing chain wear on the V6, suspension component wear, and frame corrosion in regions that use road salt.

• 
  1999-KA

  The 1999 Nissan Frontier was part of the first-generation D22 lineup, offered in XE and SE trims with the 2.4-liter KA24DE four-cylinder engine, while a 3.3-liter VG33E V6 was available on four-wheel-drive models. Changes for 1999 were minor, consisting mainly of revised option packages and new exterior colors. Common service considerations include timing chain tensioner wear, valve cover gasket and rear main seal oil leaks, and rear axle bearing wear. Rust on the frame and body, particularly in northern climates, is a frequent concern on these trucks.

• 
  2000.5_Frontier

  The 2000.5 Nissan Frontier was a mid-year update that introduced the Desert Runner trim and revised exterior styling. It was offered with a 2.4L four-cylinder or a 3.3L V6, with a supercharged V6 available on the Desert Runner. Common service items include timing belt replacement on V6 models, frame and body rust inspection, and regular transmission fluid changes. Supercharged variants also require periodic supercharger oil service.

• 
  2000.0_Frontier-VG

  The 2000 Nissan Frontier was offered with a 3.3L VG33E V6 or a 2.4L four-cylinder, and the Crew Cab body style joined the lineup for this model year. The VG33E uses a timing belt that requires periodic replacement, and valve cover gasket oil leaks are a common issue on higher-mileage examples. The available four-speed automatic transmission has been known to develop shifting problems with age, and frame and body rust is worth inspecting. Other typical service items include oxygen sensors, ignition coils, and wheel bearings, particularly on four-wheel-drive models.

• 
  1999-VG

  The 1999 Frontier was the first year of the redesigned second-generation D22 model, introducing the 3.3L VG33E V6 engine in place of the previous 3.0L V6, along with a new Crew Cab body style. The VG33E uses a timing belt with a recommended replacement interval of roughly 105,000 miles, and the water pump is commonly replaced at the same time. Common service items include valve cover gasket and rear main seal leaks, oxygen sensor replacement, and inspection of the frame and bed for rust. Four-wheel-drive models may also need attention to the front axle actuator and wheel bearings over time.

• 
  2002_Frontier

  The 2002 Nissan Frontier continued the second-generation D22 platform with minor trim and equipment changes, offering a 2.4-liter four-cylinder or a naturally aspirated 3.3-liter V6, with the supercharged V6 still available in the Desert Runner trim. Both engines use timing belts, and the 2.4-liter is an interference engine, so belt failure can cause major internal damage. Common service considerations include frame and body corrosion, particularly in regions that use road salt, as well as rear axle bearing wear and water pump replacement on higher-mileage trucks. Suspension components and brake hardware also tend to require attention as these trucks age.

• 
  1998

  The 1998 Frontier introduced Nissan's D22 generation, replacing the long-running Hardbody pickup with a redesigned body, updated suspension, and an extended cab option. Engine choices included a 2.4-liter four-cylinder and a 3.3-liter V6, paired with either a five-speed manual or four-speed automatic transmission. Common service considerations include timing belt replacement on both engines, inspection of the frame and body for rust, and attention to the vacuum-operated front axle engagement system on four-wheel-drive models.

• 
  2000.0_Frontier-KA

  The 2000 Nissan Frontier was largely a carryover within the D22 generation, with only minor equipment and option revisions for that model year. It was offered with a 2.4-liter KA24DE four-cylinder or a 3.3-liter VG33E V6, in rear-wheel or four-wheel drive configurations. The KA24DE uses solid lifters that require periodic valve lash adjustment, and higher-mileage examples may develop oil consumption or timing chain tensioner wear. Routine attention to the cooling system, water pump, distributor, and transmission fluid is commonly recommended as these trucks age.
