What owners wrote

“The low beam headlights are dangerously low. Even after you replace the bulbs, the lights remain dim. The reflective coating in the assembly has degraded to the point where almost no light is visible while driving. I read where a recall was made for RDXs made during a specific timeframe in 2014, but mine was not one of them. I have ~97k miles on the 2015 RDX.”

“Purchased car with ~96k miles. Drove at night and had extremely low road visibility due to lighting. Replaced the bulbs to a high lumen LED, did not increase lighting/visibility. My research finds this to be a known issue with a refractor found behind the headlight lens within the headlamp housing.”

“Vehicle has 80k miles. Low beam headlights are VERY dim, making it dangerous to drive at night. I haven't taken it anywhere to be inspected. Based on some searches on the Internet this is a very common issue for RDX Base models from years 2013 - 2015.”

“Ballast/Reflector in headlightz started dimming at 80,000 miles, now unable to produce light at all. This is a known factory defect that acura has been too cheap to recall. I can only see with my highbeams at night and even they barely produce light.”
