When does it fail?
Of the 21 engine complaints filed for the 2007 Honda Fit, here's the actual mileage breakdown — failures cluster heaviest at 25,000-50,000 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.
Among the 13 model years of Honda Fit in our records for engine problems, this one ranks #2 by owner-complaint volume.
No new NHTSA engine complaint has been filed on this vehicle in over 14 years — the issue may be aging out of the active population.
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.
HONDA: THE MIL IS ON WITH A STORED TROUBLE CODE. THE AIR/FUEL SENSOR IS DAMAGED.

The failure pattern owners describe
Owners describe two primary engine issues starting around 30,000–45,000 miles. First, the vehicle stalls reliably on cold starts, particularly during the first stop after firing up in temperatures below 50–75°F or when shifting to neutral (on manuals). The engine runs rough when cold but operates fine once warm. No diagnostic codes are generated, so Honda dealers claim there's nothing wrong and will not perform warranty work.
Second, owners report unpredictable misfires across all cylinders that cause the engine to die while driving—occasionally in traffic, creating a safety hazard. Swapping coil packs and spark plugs provides only temporary relief measured in days to a week. One owner replaced all four coil packs and spark plugs only to have misfires return within a week.
A third failure mode involves spark plugs loosening or ejecting from the cylinder head. One owner had a spark plug blow out at 55 mph, rupturing the cylinder head threads, melting the coil pack, and filling the cabin with fumes. Another had a loose spark plug that required a heli-coil repair, which then failed again two months later, necessitating a full cylinder head replacement.
Owners report that Honda dealers are unable or unwilling to diagnose or repair these issues, and no recall has been issued despite multiple complaints posted on online forums.

Failure modes owners describe
Cold-start stalling and rough idle
Engine stalls or runs roughly when cold, particularly during the first stop after a cold start or in ambient temperatures below 50–75°F. Stalling occurs at traffic lights, stop signs, or when shifting to neutral on a manual transmission. Problem resolves once engine reaches operating temperature. No diagnostic trouble codes are generated.
When: 30,000–45,000 miles onward; occurs on cold mornings or when ambient temperature is low
Symptoms owners cite: Engine stalls at first stop after cold start; Rough or low idle when cold; Stalling when shifting to neutral (manual transmission); Vehicle dangerously stranded in traffic; Problem disappears after engine warms up
Repairs/costs cited: No successful repairs reported. Honda dealers have been unable to diagnose due to absence of trouble codes. Owners have attempted idle adjustment without success.
Recalls/TSBs owners mention: Honda dealers have stated there is no problem and cited the absence of diagnostic codes as evidence. One dealer claimed 'Fits have no driveability problems.' No recall issued.
Repeated misfires across multiple cylinders
All four cylinders register misfires on various occasions, causing the engine to run erratically and the vehicle to die unexpectedly. Misfires occur both at startup and during driving. Check engine light may or may not illuminate. Problem is unpredictable and persists despite coil swaps, spark plug replacement, and idle adjustment.
When: 75,000–112,000 miles; one case began at 45,000 miles
Symptoms owners cite: Engine dies unexpectedly while driving or pulling into traffic; All cylinders register misfires intermittently; Check engine light may or may not illuminate; Engine sputters, hesitates, and loses power; Vehicle must be slowed when RPMs exceed 3,000
Codes mentioned: Misfire codes on specific coils, Random misfire codes on all coils
Repairs/costs cited: Coil pack swaps provide temporary relief (days to weeks). All four coil packs and spark plugs replaced in one case with only one week of relief. Fuel injector cleaner provided temporary improvement. Spark plugs with shorter diode distance partially resolved highway stalling.
Recalls/TSBs owners mention: No recalls or TSBs mentioned. Owners report that Honda dealerships cannot remedy the issue despite multiple attempts.
Loose or failed spark plugs and cylinder head damage
Spark plugs become loose in the cylinder head or fall out completely while driving. In at least one case, a spark plug was ejected at 55 mph, rupturing cylinder head threads, damaging the coil pack, and causing smoke and fumes to enter the cabin. Temporary repairs (tightening, heli-coil installation) fail within months.
When: 20,000–84,000 miles
Symptoms owners cite: Check engine light illuminates after loose spark plug; Loud bang and smoke while driving; Spark plug completely falls out of cylinder head; Fumes enter passenger cabin; Coil pack melts from overheating
Repairs/costs cited: One case required heli-coil installation ($cost not specified). Eventual repair required complete cylinder head replacement due to thread damage. Another case resulted in unrepaired vehicle.
Recalls/TSBs owners mention: Manufacturer was notified in at least one case. No recall or warranty coverage mentioned.
Unintended acceleration and loss of throttle control
Engine unexpectedly revs and vehicle accelerates without driver input, particularly after cold starts or during low-speed maneuvers. Brake and neutral shift are required to regain control. Two separate incidents reported at low speeds and highway speeds.
When: 33,000 miles
Symptoms owners cite: Engine revs without foot on accelerator; Vehicle accelerates while backing slowly; Engine continues to rev even when shifted to neutral; Brake pressure insufficient to slow vehicle
Repairs/costs cited: No repairs documented. Owner has not contacted manufacturer or dealer.
Check engine light and catalytic converter failure
Check engine light illuminates shortly after routine maintenance (spark plug and air filter replacement). Dealership diagnosis indicates catalytic converter failure despite vehicle being only moderately aged, with no reported root cause of the converter degradation.
When: Approximately one month after spark plug and air filter replacement
Symptoms owners cite: Check engine light illuminates; No other symptoms described
Repairs/costs cited: Dealership quoted $1,300+ for catalytic converter replacement; owner refused due to cost and warranty exclusion.
Recalls/TSBs owners mention: Warranty does not cover catalytic converter replacement.

Common questions
How serious is the engine problem on the 2007 Honda Fit?
It's a meaningful issue. 21 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $3,100.
At what mileage does the engine typically fail?
Across the 19 complaints that reported odometer mileage, most engine failures cluster between 40,000 and 89,000 miles, with the median around 72,000. A quarter of owners report trouble before 40,000; a quarter make it past 89,000. 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.
