Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical 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.

The failure pattern owners describe
Owners of 2017 Honda Fits report recurring electrical faults centered on the instrument cluster LCD. The fuel gauge, odometer, and MPG display frequently go blank or display corrupted data, particularly when temperatures drop. The problem typically clears after 10–15 minutes of driving, then returns on the next cold start. Owners find this hazardous because they cannot monitor fuel level or service intervals. Some owners report the speedometer also fluctuates at various speeds.
A smaller number of owners describe a more serious issue: the Bluetooth system appears to trigger a no-start condition. When pairing a phone or during active calls, the console dies and the ignition will not turn the engine over, despite a normal battery. The problem resolves only after the battery is disconnected or tested by roadside assistance.
One owner also reports all dashboard warning lights illuminating simultaneously; the dealer attributed this to rat damage to the engine wiring harness, with a $1,000 repair bill excluded from warranty. Honda supplies capsaicin tape to address rodent damage to soy-based wire coatings, but application is the owner's responsibility.
A single report documents a loud grinding noise from the push-button start mechanism during engine start and stop.

Failure modes owners describe
Instrument cluster LCD display failure — fuel/odometer/gauge blanking
The digital instrument cluster display (containing odometer, fuel gauge, temperature gauge, MPG, and trip data) goes blank, displays jumbled/corrupted data, or flickers intermittently. Owners report the display may disappear entirely or show no readable information. The problem typically resolves after 10–15 minutes of driving as the vehicle warms up, but recurs on subsequent cold starts, especially in cool, humid weather. One owner at 102,000 miles reported the speedometer, fuel gauge, and other gauges fluctuating regularly at various speeds.
When: Most frequent in cool, humid temperatures, particularly during cold morning starts; occurs at various speeds including 60 MPH; one case documented at 102,000 miles
Symptoms owners cite: LCD display goes blank or becomes jumbled/corrupted; Fuel gauge, odometer, temperature gauge, and MPG display unreadable; Speedometer fluctuates; Display flickers; Problem resolves after vehicle warms up (10–15 minutes of driving); Problem recurs on subsequent cold starts; Frequency increases as vehicle ages
Repairs/costs cited: One owner was quoted $800 for gauge replacement; another dealer diagnosed a clutch gauge requiring replacement but repair was not completed
Bluetooth system causing ignition kill/no-start condition
When the vehicle owner attempts to pair a phone with the Bluetooth system or engages in a phone call, the console suddenly goes dead and the engine will not start. The battery tests normal, but starting the vehicle becomes impossible until the battery is disconnected and reconnected (or external jump-start/battery pack testing occurs). The owner believes an electronic signal generated during Bluetooth pairing cancels the vehicle's ability to start via the ignition switch. Two incidents occurred: once while reprogramming phone numbers, and once after pairing a new phone. Contact names from Google contacts do not display on the radio console even though they appear on the phone.
When: Occurs during Bluetooth pairing or active phone calls while programming contact information
Symptoms owners cite: Console suddenly goes dead during Bluetooth pairing or phone calls; Vehicle will not start via ignition switch; Lights on console blink rapidly during attempted start; Vehicle cranks but does not ignite; Contact names from Google contacts fail to display on radio despite showing on phone; Starting capability restored after battery disconnect/reconnect or external power test
Repairs/costs cited: Roadside assistance tested battery (found no fault) and connected external battery pack; vehicle then started normally
All warning lights illuminated on dashboard
All warning lights on the dashboard illuminate simultaneously. One owner reported this occurred at 4 months of ownership (December, after August purchase). The dealer attributed the failure to rodent damage — specifically, rats had chewed through engine wiring harness. Repair cost was $1,000 and not covered under warranty. The owner notes that Honda has developed capsaicin tape to combat rodent damage to soy-based wire coatings, but this must be applied by the owner to wiring they cannot access.
When: 4 months into ownership (August purchase, December failure)
Symptoms owners cite: All dashboard warning lights illuminate simultaneously
Repairs/costs cited: Dealer determined rats chewed through engine wiring; repair cost $1,000, not covered by warranty
Recalls/TSBs owners mention: Honda has developed capsaicin tape to address rodent damage to soy-based wire coatings; tape application is consumer responsibility
Push-button start mechanism grinding noise
A loud grinding noise occurs when starting or stopping the engine using the push-button start. No additional details provided regarding frequency, severity, or impact on vehicle operation.
Symptoms owners cite: Loud grinding noise during engine start via push button; Loud grinding noise during engine stop via push button

Fuel gauage/odometer display glitches out and does not show the information. It is just a blank reading.
I bought a 2017 Honda fit ex on august 9. On december 9, all of the warning lights went on and when I took it to the dealer they informed me that rats had chewed through the engine wiring and that the repair, which is not covered by warranty, would be $1000. Honda is clearly aware of the issue of rodents affinity for their soy based wire coating, as they've developed capsaicin tape specifically…
The problem involves the Blue Tooth application in the radio console. On one occasion I was attempting to add a phone number to the list that I may use to effect hands-free calling by paring my blue-tooth phone with the car radio. On the second instance I was involved in a phone call with this system. In each case the console suddenly went dead, and it became impossible to start the vehicle. I…
The contact owns a 2017 Honda Fit. The contact stated while driving approximately 60 MPH, the instrument cluster started to flicker. The contact stated that the speedometer, fuel gauge, and other gauges were fluctuating. The contact stated that the failure became a regular failure and occurred at various speeds. The contact had taken the vehicle to a local dealer, where it was diagnosed and…
The odometer is completely useless, unable to tell mileage, fuel level and such. Several reports online of the same issue with honda fits. I could run out of gas unexpectedly, I don't know when its time to change oil.
When starting or stopping the engine with the push button, a mechanism makes a loud grinding noise.
