What stands out
Owners have filed 42 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA electrical complaint has been filed on this vehicle in over 16 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 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
The 2006 Ridgeline electrical system carries significant fire risk. The HVAC blower motor connector and wiring harness routinely melt, producing burning smells, smoke, and rapid flames that spread through the dashboard—sometimes destroying the vehicle entirely. These failures occur at varying mileages and with little warning; some owners smelled burning plastic for minutes before flames appeared. Multiple fires started at highway speeds, and recall repairs (Campaign 10V001000 and 10-012) reportedly failed to prevent recurrence in at least one case.
Instrument cluster displays freeze or go blank intermittently, disabling the odometer, door indicators, and maintenance reminders; dealers quote $575–$1000 for replacement. Odometer readings consistently exceed actual GPS distance by 10–25 miles per tank, affecting warranty calculations, yet dealerships claim many VINs fall outside the recall scope.
HVAC control knobs become unresponsive or operate at only one speed, requiring physical manipulation (banging or twisting) to function. Blower motors cycle on and off erratically or stop entirely. Blower motor resistors fail repeatedly—one owner replaced it four times in two years before discovering the underlying melted harness.
Battery discharge cycles began at first week of ownership for one owner; 15+ jump-starts were needed over months before dealer reluctantly accepted self-replacement. One vehicle suffered blown main fuse and all secondary fuses for undetermined reasons after sitting parked six hours. Door locks remain engaged in Park, preventing passenger egress in emergencies. Keyless entry systems fail; radio backlights cycle on and off with headlight operation.

On 5 nov 09, I attended a business meeting in deerfield beach. When I was ready to return to west palm beach, I turned on the truck ignition to start it and it made a couple of clicks and nothing happened. I automatically assumed it was the battery since it was over four years old and the hot weather in florida takes its toll on batteries. I also noticed that the instrument cluster did not…
I own a 2006 Honda ridgeline which I purchased new from the Honda dealership in hempstead, new york. On december 15, 2010, I was driving on utopia parkway in queens, new york when I noticed a burning smell. I had the heat on and turned it off. I pulled over to check where the smell was coming from. I saw smoke coming from the glove compartment area, I immediately called 911. When I opened the…
The maintenance minder display started blinking and then went blank at times. Dealer says to repair it requires replacing the entire instrument display at a cost of $575. Without the display you have no odometer and no door open or other indicators. *tr
The air conditioner stopped blowing air. While researching the issue I found a recall for the HVAC blower fan. This VIN number model is displaying the same symptoms as the recall for the HVAC blower. I called the dealer and they said that my VIN model number doesn't have a recall or a recall for this issue. I think is a valid recall because it is pretty much doing the same thing.
