Headlights failing or too dim by model year
What owners say
Moisture accumulating within the driver side headlight is limiting illumination and safe night driving. Photos compare driver side to passenger side.
Blind spot warning, forward collision warning, lane departure warning, lane keep assistance, and high beam lights keep flashing on dash giving a code of: U3000-49. The dealership quoted me $2000 to fix a faulty front facing camera. Research shows this is happening to thousands of people.
There are warning lights for all safety modules, The LKAS, Headlight warning system accident prevention system, collision avoidance system etc..
Dashboard lights are flickering and the headlights are intermittently turning on when the engine is off. This is a commonly reported failure and defect in the the Keyless Access Control Unit with Honda Ridgeline, Odyssey, and Pilot and Acura MDX and RDX models with keyless start. However, Honda would not recall the defect.
