RepairPal has identified the most common problems for 34 Nissan models based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The exhaust manifold on the 3.0 liter engine often warps and cracks, breaking off the studs between the cylinder head and the exhaust manifold. The noise may be most noticeable when the engine is cold.
A creaking or clicking heard while the vehicle is accelerating can be caused by dirt and corrosion build up between the splines of the front hubs and CV axle shafts. Removing, cleaning, and applying a light coat of grease on the axle shaft splines will commonly correct this concern.
This engine may burn engine oil faster than similar models. Frequent oil checks are important.
There was a service bulletin addressing a problem with front tire wear and tire noise. The tires would "growl" or "roar" at speeds under 30 mph or under moderate braking on smooth roads. The repair first involved resetting the front alignment and then either replacing or rotating (side-to-side) the front tires. This fixed the concern for some, though others still reported a recurring issue.
The AC system may blow warm air due to refrigerant loss caused by a leaking low pressure AC hose. These hoses commonly develop a leak at the hose crimp connection.
The coolant outlet on the front of the lower intake manifold may develop a coolant leak.
The Check Engine Light may illuminate due to a defective canister vent control valve in the emissions control system.
A coolant leak can develop from the front of the cylinder head that can appear to be a head gasket leak. There is a threaded plug just below the camshaft that may leak if there is corrosion present on the threads. Cleaning any residue, re-installing the plug with pipe thread (Teflon) tape, and torquing the plug to the specification typically repairs the leak.
If the vehicle fails the “State Smog Test” due to high emission readings, components in the pollution control system (air injection components) may have failed due to moisture and may need to be replaced.
