Open the full vehicle complaint log (all categories)The brake servo control unit feel simulator which reduces the simulation force provided to the brake pedal during emergency or failed conditions and is a key component of realizing a Regenerative Braking System. It provides a good pedal feeling to a driver, improves energy recovery and ensures braking security. My safety has been put at risk as that part is integral to my brake system (including the hybrid function) e.g. my car was in reverse and the brakes were not responding and had to leave my car. I towed my car to a local independent service provider and they confirmed via the OBD-II scanner that confirmed my break servo control feel simulator is bad and would need to be replaced. After doing research, the brake servo part is made in Japan by a company called Nissin. The part has been recalled in Japan and UK due to failures in similar hybrid models. The brake servo serves many functions including ensures consistency, mimics traditional braking, and provide the driver with a natural-feeling brake pedal, especially because the system relies on both regenerative braking and hydraulic friction brakes. For about 3 days I received a cluster of warning signs from my car such as traction control, brake system, brake, steering malfunction, and ACC. Given that this part directly affects braking capability and overall vehicle safety, I am deeply concerned that my safety has been compromised as the life of the part is supposed to last the life of the car (about 150,000 miles) . I respectfully request an immediate investigation, and would like to know whether this issue is covered under an existing or pending recall campaign. If not, I'd like to submit this to the recall campaign in the U.S. Please advise on the next steps for inspection, replacement, and ensuring my vehicle is safe to drive. Thank you.
ON TWO OCCASIONS I'VE HAD A BRAKE SYSTEM PROBLEM EROR MESSAGE POP UP ON MY HOME SCREEN INSIDE OF THE CAR AND ON THE HONDALINK APP 12/09/2020 AND ON 12/18/2020. I WAS LEAVING WORK ON BOTH INCIDENTS. THE MESSAGE READS: THE BRAKE SYSTEM HAS A PROBLEM OR THE BRAKE FLUID MAY BE LOW. I THERE IS NO RESISTANCE FROM THE BARK PEDAL, DOWNSHIFT TO LOWER GEARS TO SLOW THE VEHICLE. IMMEDIATELY STOP IN A SAFE PLACE AND CONTACT ROADSIDE ASSISTANCE. PART TWO: THE BRAKE SYSTEM HAS A PROBLEM. AVOID HIGH SPEEDS AND SUDDEN BRAKING. HAVE YOUR VEHICLES CHECKED BY A DEALER IMMEDIATELY. THE MESSAGE DISAPPEARS AFTER A FEW MINUTES OF BEING ON THE DISPLAY SCREEN. ALSO THE BRAKES ARE SQUEAKING MOSTLY WHEN I'M ABOUT TO TAKE OFF IN MOTION DURNING STARTUP. I TOOK THE CAR TO THE HONDA DEALERSHIP ON 01/15/2021. THEY COULD NOT GET THE CAR TO DUPLICATE THE BRAKE ERROR CODE THAT'S SHOWED UP BEFORE. THE TECH TEST DROVE MY CAR FOR 20 MILES AND NOTHING WAS FOUND. TODAY 01/16/2021 WHEN I RETURNED HOME FROM THE STORE THE BRAKES SQUEAKED AGAIN, BUT THIS TIME WHEN I WAS BACKING THE CAR IN TO MY PARKING SPACE.
