Service Bulletin - MIL flashes and vehicle will not accelerate, low power. After cycling the ignition, the symptom does not return with no stored DTCs. This issue is more common in regions with cold weather (specifically near or below freezing temperatures). Usually after a long drive (around 2 hours) and accelerating while cornering.

When does it fail?
Of the 11 engine complaints filed for the 2023 Honda Ridgeline, here's the actual mileage breakdown — failures cluster heaviest at 75,000-100,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
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.
Service Bulletin - The MIL flashes and vehicle will not accelerate, low power. After cycling the ignition, the symptom does not return with no stored DTCs. This issue is more common in regions with cold weather (specifically near or below freezing temperatures). Usually after a long drive (around 2 hours) and accelerating while cornering. Moisture accumulation in the intake manifold during long drives gets drawn into the combustion chamber while cornering, causing misfires.
full bulletin at NHTSA ↗Service Bulletin - Under certain circumstances, after coming to a stop and the idle stop feature engages, the vehicle may not automatically restart. Typically, the customer can immediately restart the vehicle by selecting Park and pushing the ENGINE START/STOP button.
full bulletin at NHTSA ↗Service Bulletin - The engine will not crank on initial startup after precipitation and sub-freezing temperatures. Water can enter the starter motor, and when temperatures drop below freezing, the water will freeze inside the starter motor. This will prevent the starter from cranking the engine.

The failure pattern owners describe
Eleven 2023 Ridgeline owners describe fuel-system and engine reliability problems emerging early in ownership. The most consistent complaint is gasoline infiltrating the engine oil—confirmed by third-party lab analysis—causing strong fuel fumes in the cabin that make passengers nauseous. One owner identified the PCV vent hose as the source. Honda dealerships have told owners this smell is normal and refused to accept independent lab results.
Engine knock is reported at 34,000 and 82,000 miles, with dealer diagnostics pointing to bearing wear and crankshaft damage. One vehicle required complete engine replacement at 20,117 miles after unexpected stall.
Cold-weather power loss appears in multiple complaints. Owners report the engine enters safety mode during or after highway driving in freezing temperatures, causing severe power loss when exiting or accelerating. One dealer explicitly stated Honda has been unable to solve this condensation-in-intake-manifold issue. A separate complaint describes condensation causing check engine light flashing and power loss at 35°F.
Minor complaints include auto start/stop delay timing in traffic, unexpected forward lurching on steep grades, and general loss of power requiring shutdown and computer reset.
Most failures occurred within the first 20,000 miles or shortly after purchase.

Failure modes owners describe
Gasoline in Oil / Fuel Odor in Cabin
Gasoline contamination of engine oil causing strong gasoline smell in cabin and passenger nausea. Oil analysis confirmed gasoline presence. Manufacturer classified the issue as normal despite third-party lab results and health complaints.
When: Approximately 6 months after purchase
Symptoms owners cite: Noxious gasoline smell in cabin; Passenger and driver nausea; Strong gasoline odor in used oil
Repairs/costs cited: Oil change performed; issue persisted. PCV vent hose identified as source in separate complaint (allowing fumes into cabin via fresh air intake).
Recalls/TSBs owners mention: American Honda stated the gasoline smell was normal and refused to accept third-party oil analysis results. Suggested seeking second opinion.
Abnormal Engine Knock / Bearing Damage
Abnormal clicking sound from engine with potential bearing damage. Dealership inspection revealed crankshaft and short block damage at 82,000 miles. Owner linked failure to NHTSA Campaign 23V751000 for older Ridgeline models.
When: Approximately 82,000 miles
Symptoms owners cite: Abnormal clicking sound at various speeds; No warning light illuminated
Codes mentioned: NHTSA Campaign 23V751000 (Engine and Engine Cooling)
Repairs/costs cited: Dealership determined crankshaft and short block required replacement. Vehicle not repaired.
Recalls/TSBs owners mention: No manufacturer contact recorded.
Loss of Power / Check Engine Light (Cold Weather)
Engine enters safety mode causing severe power loss when accelerating after highway driving in cold weather. Check engine light illuminates. Owner cannot determine loss of power until on roadway with traffic, creating safety hazard. Recurred 4-5 times despite multiple repair attempts.
When: First occurrence February 2023, after a few weeks of ownership; recurred multiple times over service history
Symptoms owners cite: Loss of power during acceleration; Check engine light illumination; Engine enters safety mode; Requires shutdown and computer reset to restore normal operation

What owners are reporting 5 most recent
The auto start/stop feature has a delay before restarting the engine after full stop in traffic. This delay is dangerous. If you don't anticipate the slight delay before pressing gas pedal to move through traffic your timing is slightly impaired by this delay. All Honda vehicles seem to be experiencing this delay and are reporting and complaining about it.
Three times we have been driving the vehicle on a steep grade when the vehicle lurches forward in a short accelerated sortie.
