Of the 17 electrical complaints filed for the 2007 Honda Ridgeline, here's the actual mileage breakdown — failures cluster heaviest at 50,000-75,000 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.
No new NHTSA electrical complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
Should the wiring insulation melt and the exposed wires make contact with each other (short circuit), a fire may occur.
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 TYPE 4 SYSTEM IS DIFFERENT THAN PREVIOUS SYSTEMS IN THAT THE TRANSPONDER ID CODE IN THE KEY IS A ROLLING-TYPE CODE INSTEAD OF A FIXED CODE. IN THIS SERVICE BULLETIN, A PROGRAMMED IGNITION KEY REFERS TO A TRANSPONDER-TYPE KEY THAT HAS BEEN CUT TO FIT THE IGNITION SWITCH AND WHOSE TRANSPONDER ID CODE IS RECOGNIZED BY THE IMMOBILIZER SYSTEM. IF YOU TRY TO START THE ENGINE WITHOUT A PROGRAMMED IGNITION KEY, THE ENGINE CRANKS, BUT IT DOES NOT START.

Multiple owners report their 2007 Ridgeline's air conditioning and heater blower motor wiring harness melting, and in several cases this melting has led to fires while the truck was parked or being driven. One owner smelled acrid odor and saw flames at 29,400 miles; the dealer acknowledged a known problem with the fan control switch but hadn't warned the owner. Another reported 4 feet of melted harness at 52,000 miles that required a nationwide back-order part costing $730 out of pocket. A third owner experienced smoke and flames from the rear tail light area an hour after leaving the dealer for routine maintenance; the fire department had to extinguish it. Honda issued recall 10V001000 for the electrical system/instrument panel to address the wiring harness, but some owners report parts were unavailable for weeks or the recall repair was incomplete (blower motor protective cover not installed).
Owners also describe sudden engine power loss with multiple warning lights (Check Engine, VTM4, VSA) illuminating together, requiring them to pull over and restart the truck. Other electrical complaints include door locks opening while driving, random alarm activation, ignition failure at 100,000 miles, brake interlock switch melting internally, low beam headlight failure, and in one case, air bags failing to deploy during a collision due to a faulty ground wire short circuit.

A/C and heater blower motor circuit overheats, causing wiring harness to melt. Owners report the A/C fan running continuously even when off, then melted harnesses are found during repair. In multiple cases, melting has progressed to fire with flames and smoke from the dash or under the hood.
When: Occurs across a wide mileage range: 29,400 miles up to 118,166 miles. Multiple fires occurred within hours of diagnosis or without warning while vehicle was parked or during normal driving.
Symptoms owners cite: A/C fan runs continuously with A/C switched off; A/C stops blowing cold air; Smoke or burning smell from dashboard or passenger hood area; Flames visible from dashboard or under hood; Blower motor and A/C control head/wiring harness melted; Heater motor stops blowing
Repairs/costs cited: Dealerships have replaced transistor, blower motor, and wiring harness. One owner paid $730.83 out of pocket; wiring harness parts have been on nationwide back order. Recall 10V001000 addressed this with wiring harness replacement, but some vehicles were repaired without installing the blower motor protective cover specified in the recall remedy.
Recalls/TSBs owners mention: NHTSA Recall 10V001000 (Electrical System: Instrument Panel) issued to address wiring harness concerns. Some owners reported the recall repair was delayed due to parts unavailability. Recall 16V344000 (Air Bags) also referenced but parts were unavailable at time of notification.

Tl* the contact owns a 2007 Honda ridgeline. The contact stated that the ignition became inoperable and failed to turn. The failure recurred on several occasions. The vehicle was taken to a dealer. The technician diagnosed that the vehicle needed a new ignition and key. The vehicle was repaired. The manufacturer was not notified of the issue. The failure mileage was 100,000.
Started vehicle and noticed that both low beam headlights were not working. All other running lights were working (tail lights, parking lights, fog lights, turn signals, etc). High beam headlights were both working. Had replaced the headlight bulbs about a month ago. Have had no problems prior to the failure. In researching the problem I found a prior recall for the headlight wiring on earlier…
It's a meaningful issue. 17 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $850.
Across the 16 complaints that reported odometer mileage, most electrical failures cluster between 52,478 and 118,166 miles, with the median around 76,000. A quarter of owners report trouble before 52,478; a quarter make it past 118,166. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
