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.

What owners are reporting 5 most recent
After replacing fuel injectors recently I have no warning lights on but the car has been stalling and pulling. Today on the freeway as I attempted to accelerate from 30 mph my car jerked and pulled 3 times harshly almost causing an accident. Still no warning lights and this has happened multiple times. I have submitted a prior concern and it has not been addressed and the problem only continues…
The car will stall while on the freeway. Had fuel injectors replaced and still does not drive well. I am now being told I may have to look at the fuel pump which should be working automatically. I have now invested almost 3,000 on a car with less than 90,000 miles on it that is maintained religiously so that nothing happens to it.
Rattling noise coming from engine when starting engine cold
At cold start up, the engine rattles loudly for about 2 seconds. This is intermittent and occurs on cold starts when the car has not been started for 6-8 hours.
Like 4 others on NHTSA, I am reporting intermittent cold start rattle coming from the VTC actuator. I have tried the following: cleaning the intake valves, changing the oil every 3k miles, using a high quality oil filter with a silicone drain back valve, and using Top Tier fuel on every fuel up. 2015-2016 Honda Fits have a TSB regarding this issue, and my 2017 Honda Fit also has this issue.…

Common questions
How serious is the engine problem on the 2017 Honda Fit?
It's a documented issue but not catastrophic. 6 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?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
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.
