The Nissan Titan has been around since 2004 and currently has two generations. Like many cars and trucks, the Titan has common issues in some of its models. Here we discuss common Nissan Titan problems with their 1st generation, years 2004 to 2015.
Top 5 Issues 1st Gen Nissan Titan (2004 to 2015)
1. Transmission Problems: Coolant Mixing with the Transmission Fluid
Symptoms of Transmission Problems
- Lack of engine power
- Poor shifting
- Coolant level is often low
- Sudsy transmission fluid
- Dark pudding-like coolant
Another indicator of the coolant mixing with the transmission fluid is the coolant disappearing from the radiator after topping it off.
Causes of Transmission Problems on the 1st Gen Nissan Titan
The transmission lines that run through the radiator can crack, allowing coolant to flow into the transmission.
How to Fix Coolant Mixed with the Transmission Fluid
Check the Transmission Fluid’s Condition
If you need to keep refilling the coolant, it may not be the head gaskets. Check the transmission fluid first.
How to Check the Transmission Fluid on the 2004 to 2015 Nissan Titan
- Warm the Engine Up to Operating Temperature
Warm the engine up to operating temperature to get an accurate reading of the transmission fluid
- Park on Level Ground
Park on level ground away from bystanders or traffic
- Remove the Bolt from the Transmission Dipstick Bracket
Loosen and remove the bolt from the transmission dipstick bracket with a 10mm socket and ratchet
- Remove the Transmission Fluid Dipstick
Remove the dipstick and clean it with a cloth
- Reinsert and Remove the Transmission Fluid Dipstick
Check the condition of the transmission fluid. If there is coolant in the transmission fluid, it will separate in the form of bubbles.
Check the Coolant Overflow Tank for Mud-Like Residue
With the truck cool, remove the coolant overflow tank cap. If the coolant is mixing with the transmission fluid, a mud-like fluid will accumulate around the cap.
Flush or Repair the Transmission and Replace the Radiator
- If this problem is caught before there is damage to the transmission, replacing the radiator and flushing the transmission fluid will fix this issue.
- If the transmission is damaged, the transmission will need to be rebuilt or replaced along with the radiator.
2. Broken Clock Spring Wiring
Symptoms of a Broken Clock Spring
- Air bag light is on
- Check engine light for code P1654 or U1000
Causes of a Broken Clock Spring
The wiring to the clock spring can fray and break off in the 2004 to 2015 Nissan Titan.
How to Fix a Broken Clock Spring
- Clear the code
- Start the truck
- Turn the steering wheel from stop-to-stop, i.e. a full 360 degrees turn or 180 degrees each way.
- If the check engine light and air bag light return, there is likely a problem with the clock spring.
3. Catalytic Converter Failure
Symptoms of Bad Catalytic Convertors or Fuel Pump Problems on the 2004 to 2015 Nissan Titan
- Lack of power when accelerating
Causes of Bad Catalytic Convertors
Low fuel pressure can damage the catalytic convertors.
How to Fix Bad Catalytic Convertors
Check the fuel pressure. If the fuel pressure is below 51 psi, there is a lean condition, meaning the truck is starved for fuel and the fuel pump needs to be replaced. Not replacing the fuel pump as soon as possible can damage the catalytic convertors.
4. Leaky Axle Seals
Symptoms of Leaking Axle Seals
- Differential fluid leaking from the axle seals near the wheel
Causes of Leaky Axle Seals
There is no vent tube on the rear differential of the 1st gen Nissan Titan. The differential builds up pressure and eventually differential fluid leaks from the axle seals.

5. Worn Interior Trim and Parts
Symptoms of Worn Interior Trim
- Chipped or worn door handles
- Faded buttons and switches
- Worn or faded trim pieces
Causes of Worn Interior Trim
Interior trim and paint can chip, wear out, and fade over time.
