My 2009 Honda Ridgeline RT occasionally displays the yellow Check engine, VTM-4, VSA and traction control warning diamond lights a few seconds after starting. All the lights turn on at once but there is no noticeable issues with the vehicle. No feeling of a misfire or steering issues. The lights will only turn on within a few seconds of starting the Ridgeline. When I turn the ignition off and back on again all the lights clear except for the check engine light. When I read the codes on the OBD the only code says Misfire in Cylinder (#). The cylinder doesn't matter because it changes each time. I have had two Honda dealerships and one local repair shop look at it and they all agree there is no evidence of a misfire even when replacing plugs and coils. I would not expect a misfire to be linked with the stability control system. After starting the Ridgeline 6-10 times the check engine light turns off until the next time all of the lights light up. Sometimes I go weeks without seeing the lights other times its a daily occurrence. I have driven 30K miles and almost 12 months with this issue and haven't noticed any mechanical issues with the Ridgeline. The truck handles and runs perfectly. Anyone else have a similar issue. See the attached picture. Disregard the TPMS light that is a separate issue.
