Transmission: CVT features and all-wheel drive
The most talked about part Nissan Murano 2003 is a continuously variable transmission CVT (Continuously Variable Transmission). It was one of the first mainstream attempts to introduce such technology into crossovers, which brought both benefits and challenges. The variator provides a smooth ride, eliminating jerks when changing gears, but requires special attention to maintenance.
The design of the variator includes a belt and two conical pulleys, which makes it sensitive to the quality of the working fluid and operating conditions. Torque converter and the torque transmission belt may fail if routine maintenance is ignored. CVT fluid replacement must be carried out strictly according to schedule, otherwise the service life of the box is sharply reduced.
All-wheel drive in Nissan Murano The 2003 is a plug-in model with predominantly front-wheel drive under normal conditions. The system automatically redistributes torque between the axles when slipping, which makes the car feel confident on wet roads or light off-road conditions. Center coupling works reliably, but requires checking the condition of bearings and seals.
⚠️ Attention: Towing is strictly prohibited Nissan Murano 2003 with the engine running for short distances without disconnecting the drive. This can lead to immediate failure of the variator due to lack of lubrication.
☑️ Checking the variator before purchasing
Suspension and road handling
Suspension Nissan Murano The 2003 is designed with an emphasis on comfort, making it great for urban environments and country trails. The MacPherson type front suspension and multi-link rear suspension provide excellent ride smoothness and smooth out bumps. Anti-roll bars help maintain directional stability when cornering.
The steering is power-assisted, providing light steering at low speeds and precision at high speeds. However, over time, play may appear in the steering rack, requiring repair or replacement. Steering rack - this is a weak point that often requires attention after 150 thousand kilometers.
Wheels and tires play an important role in comfort, since the suspension is sensitive to the hardness of the rubber. Using low profile tires can make the ride too harsh. It is recommended to choose high profile tires to maintain performance pendants and passenger comfort.
- 🔧 Regularly check the condition of the silent blocks of the levers and stabilizer struts.
- 🚗 Check wheel alignment angles (wheel alignment) every 15-20 thousand kilometers.
- ⚙️ Change shock absorbers in pairs to avoid body distortion.
What to do if there is a knock in the suspension?
Often the knocking noise is caused by wear on the stabilizer bushings or shock absorber support bearings. It is recommended to carry out diagnostics on a lift, since some defects are not visible in the pit.
Typical faults and repair issues
Despite the overall reliability, Nissan Murano 2003 has a number of specific problems characteristic of this age. One of the most common problems is with the ignition system, where the ignition coils can fail, causing misfires. Ignition coils are consumables and require replacement when engine errors occur.
It is also worth paying attention to the air conditioning system, which in 2003 models often loses refrigerant due to wear of the seals. The air conditioning compressor may be noisy or stop working altogether. Air conditioner condenser often damaged by stones, which leads to freon leakage.
The electrical system is generally reliable, but problems may occur with the throttle position sensors or idle air control. Errors at work electronics often lead to unstable engine operation at idle. Diagnostics must be carried out using specialized equipment.
| Component | Typical problem | Symptoms | Recommended Solution |
|---|---|---|---|
| Ignition coil | Failure | Misfires, engine tripping | Replacing a set of coils |
