Drove about 15 miles on a quiet highway tonight at about 55 MPH. The big BREAK now light came on about three times -- but none of those times was there a car anywhere close to in front of me. My car is about a month old, and they already had it for a few days to replace both front control arms, and I went back yesterday after I decided to require them to realign it when they didn't after they replaced the control arms, so not excited to bring it back in ... but, not sure what to do about this. Haven't noticed it driving on city streets.

Was there anything stuck on your acura logo, thats where radar is. Other than that, take it in, have them recalibrate it
