I have a 2014 Renault Fluence 1.5 tdi. The brake pedal is gone very hard off and on. Also sometimes a sign comes on to start the car by pressing the brake. I always use the clutch. Thanks. Jim
Hi Jim,
A known issue with that car is the brake pedal position switch. It causes all kinds of error messages and could well be what's causing your problems. Bring the car to a good mechanic and mention that so that can check it.
