My 2007 Fit is making these irritating popping noises when I'm accelerating slowly in 1st gear usually around 2-5 mph and also when I'm braking close to a stop (around 5 mph). It sounds like it's coming from underneath the car (either the suspension or brakes?). It pops only once upon acceleration and once upon deceleration. Sounds like 'tok'. I went over some bumps pretty hard a few weeks ago. I also have 17" wheels. Does anyone else have this problem? I wonder what is causing it and whether or not it's covered under warranty.
