What stands out
Of the 7 model years of Nissan Xterra we track for electrical problems, this one carries the most owner complaints on file — 26.
Owners have filed 26 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

full bulletin at NHTSA ↗12 VOLT BATTERY TESTING FOR IN-SERVICE VEHICLES SERVICE INFORMATION The following Service Information lists NNA procedural recommendations for establishing good connections while performing 12V battery testing. These recommendations are expected to promote uniformity during the connection process, therefore reducing the number of incorrect âTest with DCAâ and âReplaceâ results. HINT: If 12 volt batteries are allowed to discharge for a prolonged period of time, battery life may be drastically reduced. This condition may lead to premature battery replacement and customer dissatisfaction. IMPORTANT: ï· CPX-900 is now an accepted testing tool to use along with or in place of the DSS-500
full bulletin at NHTSA ↗SILICONE-BASED LUBRICANT OR GREASE CAN DAMAGE ELECTRICAL COMPONENTS SERVICE INFORMATION Do not apply Silicone-based lubricants or grease to, or around, any interior electrical components. To avoid the risk of death or severe personal injury, do not directly spray Silicone-based lubricant or grease, or inadvertently overspray Silicone-based lubricant or grease onto any interior electrical components. These types of lubricants can be detrimental to the proper operation of electrical components.

The failure pattern owners describe
The 2006 Xterra electrical system generates consistent complaints across a tight cluster of failures. Fuel gauge malfunction dominates: owners describe gauges reading empty on full tanks, staying pegged at zero, or going off-chart, often with Check Engine lights lit simultaneously. Diagnostic code P0463 (fuel level sensor) appears in documented cases; owners cite defective fuel pump module assemblies as the culprit. Repairs run $550 to $600 at dealerships, and several owners report failures recurring even after repair or fuel-system recall work (NHTSA campaign 10V075000).
TPMS lights illuminate continuously and resist reset, happening at 75,000+ miles despite correct tire pressures. Owners report wheels feeling loose alongside these warnings.
Beyond gauges, the Xterra displays broader electrical instability: camshaft and crankshaft position sensors fail repeatedly (one owner replaced both twice in a year), causing unpredictable stalling at any speed or while parked. Dashboard lights malfunction—VDC and SLIP lights cycle on and off without stored fault codes, and some vehicles lose all dash illumination. Rear door locks jam solid, trapping occupants. A wiring harness defect (missing N-BUS connector in the dash) was reported unresolved despite Nissan contact. One documented fire involved electrical spark under the hood.
Dealers frequently struggle to diagnose these faults, reporting no hard error codes when customers present repeated symptoms.

Failure modes owners describe
Fuel gauge malfunction
Fuel gauge reads incorrectly or stays stuck at empty despite having fuel in tank. Commonly triggered by fuel level sensor (fuel pump module assembly) failure. Check Engine light illuminates simultaneously.
When: 31,000 to 159,000 miles; occurs throughout vehicle lifespan
Symptoms owners cite: Fuel gauge reads empty when tank is full or has fuel; Gauge goes off-chart when filled; Gauge unreliable and untrustworthy; Low fuel warning light stays on continuously; Check Engine light illuminates with fuel gauge failure
Codes mentioned: P0463 (fuel level sensor malfunction)
Repairs/costs cited: $600 dealer repair typical for fuel pump module assembly; owners report $550 quoted costs; some repairs performed under fuel recall campaign 10V075000
Recalls/TSBs owners mention: NHTSA campaign 10V075000 covers fuel system issues; owners note Pathfinder had recall for identical problem; Nissan dismisses complaints; one vehicle repaired under campaign but failure recurred
TPMS light malfunction
Tire Pressure Monitoring System light illuminates continuously even when all tires are at correct pressure. Reset provides only temporary relief; light recurs shortly after.
When: 75,000 to 91,000 miles
Symptoms owners cite: TPMS light stays on continuously; Light remains on despite correct tire pressure; Reset only works temporarily; Wheels felt loose (related complaint)
Recalls/TSBs owners mention: No TPMS recall campaign listed; owners request it be added to recall list
Engine stalling and loss of motive power
Vehicle stalls unexpectedly while driving, with engine dying as if key was turned off. Can occur at highway speeds or while parked, creating hazard. Related to sensor failures.
When: Occurring repeatedly; one incident at 159,000 miles
Symptoms owners cite: Vehicle stalls without warning while driving or parked; Loss of motive power at 60 mph; Fuel level warning light illuminated during stall event; Dies as if key was turned off
Repairs/costs cited: One vehicle towed after stall; not repaired
Camshaft and crankshaft position sensor failure
Camshaft and crankshaft position sensors fail repeatedly, causing vehicle to stall unpredictably. Owner replaced both sensors twice within one year of ownership.
When: Recurring; replaced twice in one year of ownership
Symptoms owners cite: Vehicle dies at any time as if key turned off; Occurs whether driving or parked; Dangerous when occurs during driving
Repairs/costs cited: Camshaft position sensors replaced twice; crankshaft position sensors replaced twice within one year
Starter and ignition system problems
Multiple dashboard warning lights illuminate when key turned to on position and engine fails to crank normally. Starter replaced but problem recurred; diagnostic revealed coil pack misfire code and IPDM recall reference.
When: Problem recurs one week after starter replacement
Symptoms owners cite: All dashboard lights come on when key turned to on position; Motor does not turn over properly; Problem recurs after starter replacement

Rear passenger doors keep locking and won't open/unlock at all. OEM parts were used for actuator and other issues, however it has happened again. Very unsafe, as if they jam, we can't exit the vehicle and have to climb to the rear hatch or through the front seats. If there were an accident, it would be detrimental. *tr
