1999–2004 Nissan Frontier common problems and fixes
Check that the fuel sending unit recall (stalling, fuel leaks) and the steering shaft corrosion recall were done, and look for cracked exhaust manifolds and rear oil leaks on the V6.
What owners should know
Covers 1999–2004 · 2.4L four, 3.3L V6 (supercharged option) · Updated 2026-10-05
The first Frontier came with a 2.4L four or a 3.3L V6. For 1999 the V6 was offered only on 4x4 King Cab trucks (SE-V6 and XE-V6), with a 5-speed manual or 4-speed automatic, and it spread to more models in later years. A supercharged version of the V6 was added later in the run. It was sold until the redesign for 2005.
We counted 657 owner complaints filed with NHTSA for 1999–2004 Frontiers (retrieved October 5, 2026; each complaint counted once): 318 from V6s and 200 from four-cylinders, identified by VIN; the rest couldn't be matched to an engine. We left out 11 whose VIN belongs to another vehicle (such as an Xterra or Pathfinder). No single problem stands out. Complaint counts show what owners report most often, not how many trucks have a problem.
At a glance
- The fuel system is the most reported area, mostly the recalled fuel sending unit.
- Brakes and steering come next, with a recall for steering shafts that can corrode and crack.
- On forums, owners mention cracked exhaust manifolds and rear engine oil leaks on the V6.
Fuel system
123 complaints are filed under NHTSA's fuel system categories, and about 75 mention stalling, fuel leaks or smells, the fuel gauge or the sending unit. Nissan recalled certain 1999–2003 V6 trucks because the fuel pump terminal on the sending unit could crack and corrode (04V230000).
Steering
Nissan recalled certain 2002–2004 trucks because the lower steering column joint can corrode, and the shaft can then crack during tight low-speed turns (10V554000).
Engine
The 3.3L V6 has a timing belt. Nissan's 2004 schedule says to replace it every 105,000 miles or 84 months, whichever comes first. On Club Frontier and Expedition Portal, owners also report cracked exhaust manifolds and oil leaks at the back of the engine on the V6.
Recalls to check
- Rear axle that can let water in through the ABS sensor on 2001–2003 trucks (02V299000)
- Engine computer on some 2002 supercharged trucks (02V298000)
Before you buy
- Check open recalls at nhtsa.gov/recalls with the VIN.
- Ask when the timing belt was last replaced on a V6.
- Listen for an exhaust tick on a cold start and look for oil at the back of the engine.
- Bring our used truck inspection checklist.

Common failures & how to fix them
Parts and video buttons search for your 1999-2004 Nissan Frontier. Always confirm a part fits using your VIN. Brakes, steering, fuel and airbag work affects your safety, so if you're not sure, have a qualified mechanic do it.
Fuel sending unit terminal cracks (1999–2003 V6)
Dealer jobSigns: Stalling, a fuel gauge that reads wrong, or a fuel smell from the tank.
Fix: Covered by a Nissan recall that replaces the fuel sending unit on 1999–2003 V6 trucks. Recalls cover only specific trucks, so check this VIN at nhtsa.gov/recalls to see if it's included and whether the repair was done.
May be covered free by recall 04V230000. Check the VIN at nhtsa.gov/recalls.
Lower steering shaft can corrode and crack (2002–2004)
Dealer jobSigns: Stiff or notchy steering, especially when turning the wheel a lot at low speed.
Fix: Covered by a Nissan recall for certain 2002–2004 trucks built July 9, 2001 to October 20, 2004, which inspects and replaces the lower steering column shaft. Recalls cover only specific trucks, so check this VIN at nhtsa.gov/recalls to see if it's included and whether the repair was done.
May be covered free by recall 10V554000. Check the VIN at nhtsa.gov/recalls.
Cracked exhaust manifold (3.3L V6)
Hard DIYSigns: A ticking noise that's loudest when the engine is cold, or an exhaust smell under the hood.
Fix: Have a shop confirm the leak first; a ticking noise can also be a leaking gasket, a loose heat shield or a valvetrain noise. If the manifold is cracked, it's replaced with a new gasket, and owners report the studs often break and need to be drilled out.
Timing belt is due (3.3L V6)
Hard DIYSigns: No warning: the V6 uses a timing belt, and an old belt can snap and stop the engine.
Fix: Nissan's maintenance schedule for the 2004 3.3L V6 says to replace the timing belt every 105,000 miles or 84 months (7 years), whichever comes first; check the owner's manual for earlier years. Owners usually replace the water pump at the same time. With these trucks now well past 7 years, ask for receipts showing when it was last done; if there aren't any, budget for it.
