Owners have filed 33 engine 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.
Among the 10 model years of Nissan Murano in our records for engine problems, this one ranks #2 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine 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.
OBD II EVAP Tube Warranty Enhancement The update below was sent out to Regions and Dealers in August of this year. We are re-circulating this update to make regional and dealer personnel aware that we are re-notifying customers at this time.
full bulletin at NHTSA ↗SERVICE INFORMATION After ECM reprogramming, the Calibration Verification Number (CVN) needs to be automatically calculated prior to State emissions testing (also known as Inspection Maintainence, I/M, or SMOG testing depending upon location). Allowing the vehicle to idle for 22 minutes will allow for faster CVN calculation. It is recommended that customers utilize this method if the vehicle needs to be tested for emissions soon after ECM reprogramming. See this bulletin for further detail.

The failure pattern owners describe
Owners describe a 2005 Murano with chronic engine reliability problems starting early in ownership. Stalling occurs without warning at traffic lights, during acceleration, and on highways at speeds from 5 mph to 55 mph. Check engine lights are common, with diagnostics pointing to failed camshaft position sensors (both banks), crankshaft position sensors, and throttle bodies. One owner reported a cam sensor failure at 52,000 miles ($247 repair); another needed replacement at 128,000 miles. Sensors are reportedly made of plastic and wear out prematurely.
Intake air ducts come loose repeatedly, causing stalling in traffic; one owner reported the issue recurring after a dealer fix. Throttle body failures have forced vehicles into limp mode at speeds under 20 mph. Alternator tensioner brackets snap at 56,000–66,000 miles, sometimes requiring engine removal.
Fuel-system odor complaints describe strong gasoline smell persisting despite fuel system replacement, recall service, and evaporator canister work. One owner reported health effects from fumes.
Engine knock (pinging) occurs even with premium fuel. Isolated reports cite oil leaking into the throttle body, misfiring with black smoke from the muffler, and transfer case breakage. Several owners note Nissan either refused warranty coverage or could not diagnose the problem via computer, leaving them to cover repairs out-of-pocket.

Common questions
How serious is the engine problem on the 2005 Nissan Murano?
It's a documented issue but not catastrophic. 33 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.
At what mileage does the engine typically fail?
Across the 29 complaints that reported odometer mileage, most engine failures cluster between 15,000 and 86,000 miles, with the median around 52,244. A quarter of owners report trouble before 15,000; a quarter make it past 86,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
