P0300 on a 2023 Nissan Rogue

P0300 is a generic OBD2 powertrain code for random or multiple cylinder misfire. Unlike P0301 through P0308, it does not point to one specific cylinder, so the cause can be ignition, fuel, air, sensor, or mechanical.

Most common causes on the 2023 Nissan Rogue

Ranked from 660 NHTSA owner complaints filed for this vehicle.

Sort by:

1
Engine main-bearing wear/failure (NHTSA recall 26V080, VC-Turbo lubrication defect)
High severity
A dominant, recall-documented pattern on this engine: bearing degradation causes rough idle, violent shaking/vibration, and stalling before full engine failure — mechanical symptoms that read as (and can trigger) random misfire counts.
Reported in 8 NHTSA complaints
2
Head gasket failure / coolant intrusion into a cylinder
High severity
Owners report a bad head gasket diagnosis, a coolant leak smelled from the exhaust requiring constant refills, and white/gray exhaust smoke — coolant entering a cylinder fouls combustion and causes misfire.
Reported in 3 NHTSA complaints
3
EGR valve or EGR sensor failure
Medium severity
Dealer diagnostics on this fleet directly identified EGR valve/sensor faults during stalling/power-loss events, and one dealer blamed a failing EGR valve for engine shaking.
Reported in 2 NHTSA complaints
Parts:EGR valve
4
Failed MAF sensor / idle air control fault
Medium severity
One owner's scan pulled P0101 (MAF circuit) and P0507 (idle control RPM higher than expected) — a MAF that misreports incoming air directly causes cylinder-to-cylinder fueling errors and misfire.
Reported in 1 NHTSA complaint
Parts:MAF sensor idle air control valve
5
Variable valve timing (VVT) actuator/solenoid fault
Medium severity
A certified mechanic pulled DTC P0012 (intake camshaft timing over-retarded) on this vehicle; incorrect valve timing disrupts cylinder filling and combustion, producing misfire-like symptoms.
Reported in 1 NHTSA complaint
Parts:VVT solenoid
6
Worn or fouled spark plugs
Low severity
Standard misfire cause; inspect gap/condition on any cylinder(s) flagged.
Common cause
Parts:spark plugs
7
Failing ignition coil(s)
Medium severity
A weak coil-on-plug unit drops spark energy on that cylinder, producing a recurring misfire.
Common cause
Parts:ignition coil
8
Vacuum/intake leaks
Medium severity
Unmetered air entering past a cracked hose or gasket leans out one or more cylinders enough to misfire.
Common cause
9
Carbon-fouled intake valves
Medium severity
This direct-injection turbo 3-cylinder doesn't wash intake valves with fuel, so carbon buildup is common and disrupts airflow/combustion.

These causes are aggregated from NHTSA owner complaints and general repair knowledge — this is not a diagnosis. P0300 on your car still needs shop confirmation before any repair.

Common symptoms

Flashing or steady check engine light
Rough idle
Shaking under acceleration
Loss of power
Fuel smell from exhaust

What to check before replacing parts

Scan for cylinder-specific misfire codes

Look for: A companion P0301–P0308 pins the misfire to one cylinder — start there. P0300 with no cylinder code points at something hitting several at once: fuel pressure, a large vacuum leak, or timing.

Inspect the spark plugs and coils

Look for: Pull the plugs: black/sooty = rich, oily = oil intrusion, white/blistered = lean or overheating, cracked porcelain or an out-of-spec gap = replace. Then swap a coil to another cylinder — if a cylinder-specific code follows the coil, the coil is bad.

Check fuel trims for a vacuum leak

Look for: High positive short- and long-term trims (worst at idle, improving as RPM rises) mean unmetered air is getting in. Smoke-test the intake and listen for hissing.

Verify fuel pressure

Look for: Compare running/cranking pressure to the vehicle spec. Low or dropping pressure starves multiple cylinders and reads as a random misfire — suspect the pump, filter, or regulator.

Compression / leak-down test if ignition and fuel check out

Look for: A cylinder 15%+ below the others, or leak-down hissing from the intake (intake valve), exhaust (exhaust valve), or oil filler (rings), means the misfire is mechanical — not a swap-in part.
