Hello, My 2018 Acura MDX has moisture and water inside the inner tailgate (trunk) tail light assembly, which caused the light to stop working. I understand there is a recall affecting some 2014–2020 Acura MDX vehicles related to moisture entering the tailgate light assembly, and my vehicle appears to have the same issue. Recall link: [XXX] Last week I visited the Acura dealership(Acura Columbus) in Dublin, OH for a fuel pump recall service. During that visit, the technician also noticed the water inside the inner tail light but quoted about $750 for the repair. Although my VIN does not show this recall, my vehicle is experiencing the same problem described. Could you please review and advise if this may qualify for recall coverage or goodwill assistance? Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

MERGING ONTO A 6 LANE HIGHWAY, SPECIFICALLY THE 3 NORTHBOUND LANES, THE COLLISION MITIGATION BRAKING SYSTEM ACTIVATED SUDDENLY. I WAS MOVING FROM THE RIGHT LANE TO THE MIDDLE LANE ACCELERATING AS NEEDED TO MAINTAIN THE APPROPRIATE SPEED WITH THE MIDDLE LANE. AS I BEGAN TO EASE OFF THE ACCELERATOR, THE CMBS SLAMMED ON THE BRAKES. SPEED WENT FROM 60 TO 25MPH ON A CONGESTED HIGHWAY AT RUSH HOUR. THE CAR BEHIND ME SWERVED TO AVOID. I FRANTICALLY STOMPED ON THE GAS PEDAL TO TRY TO KEEP GOING, EVENTUALLY THE CAR STOPPED BRAKING AND I CONTINUED. THE CAR IN FRONT OF ME WAS A FEW HUNDRED FEET AWAY AND NOT BRAKING AT THE TIME THIS HAPPENED. TIME OF DAY WAS JUST BEFORE SUNRISE.

I WAS TRAVELING ABOUT 35-40 MPH APPROACHING A SIDE STREET TO THE RIGHT. THE CAR IN FRONT OF ME SLOWED TO TURN RIGHT. THE 'BRAKE' LIGHT FLASHED AS IT TYPICALLY DOES. I SLOWED BUT DID NOT STOP SINCE THE CAR IN FRONT OF ME WAS CONTINUING IT'S TURN AND MOVING AWAY FROM ME. THERE WAS A CAR AT THE STOP SIGN ON THE SIDE STREET WAITING TO TURN ONTO THE ROAD I WAS TRAVELING. AS THE CAR IN FRONT OF ME WAS COMPLETING ITS TURN MY CARS BRAKING SYSTEM ENGAGED AND BROUGHT THE VEHICLE TO A COMPLETE STOP IN FRONT OF THE CAR ON THE SIDE STREET WITH NO VEHICLES IN FRONT OF ME. THE DEALER SAYS THERE ARE NO ERRORS RECORDED ON THE COMPUTER SYSTEM AND THEY COULD NOT DUPLICATE WHAT HAPPENED.

WHILE DRIVING DOWNHILL A CAR APPROX 1000 FEET AHEAD OF ME WAS SLOWING DOWN TO TURN RIGHT WHILE THE CAR WAS STILL TURNING BUT COMPLETELY OUT OF THE INTERSECTION THE AUTOMATIC BRAKES CAME ON AND CAME TO A COMPLETE STOP. THE CAR THAT TURNED RIGHT WAS DOWN THE STREET IT HAD TURNED ON COMPLETELY OUT OF SENSOR RANGE AND THE AUTOMATIC BRAKES WOULD NOT LET OFF, WHEN TRYING TO ACCELERATE IT GOT STUCK IN GEAR BUT WOULD NOT BUDGE. LIKE WHEN YOU DONT SHIFT A GEAR FOR TOO LONG IN A STICK SHIFT CAR. FINALLY THE BRAKES LET OFF AND I WAS ABLE TO DRIVE BUT FURTHER DOWN THE SAME HILL THE AUTOMATIC BRAKES DID THE SAME THING AGAIN WHILE TRYING TO ACCELERATE TO CHANGE LANES, THERE WAS NOT A SINGLE CAR INFRONT OF ME AT THIS POINT AND NO REASON FOR THE AUTOMATIC BRAKES TO DO THIS. BOTH INCIDENTS ALMOST CAUSED ME TO BE REAR ENDED.

PURCHASED ACURA MDX IN JANUARY OF 2018 SO IT IS NOW 3 MONTHS. I BELIEVE THERE IS SOMETHING SIGNIFICANTLY WRONG WITH ITS AUTOMATIC BRAKING SYSTEM. I WAS DRIVING DOWN A HILL ON A RESIDENTAL, FAST PACED ROAD, WITH A GUARDRAIL TO MY RIGHT SIDE AND ANOTHER CAR PASSING ME ON THE LEFT SIDE. WE BOTH WE TRAVELING AT THE SPEED LIMIT OF 40 MILES PER HOUR WHEN ALL OF A SUDDEN MY CAR'S BRAKES WENT ON, CAUSING ME TO SWERVE INTO THE GUARDRAIL. FROM THERE, I WAS THROWN INTO ONCOMING TRAFFIC CAUSING A COLLISON. I BELIEVE THE SYSTEM BECAME CONFUSED AND STEPPED ON THE BRAKES WHEN IT DETECTED THE OTHER VEHICLE ACCELERATING TOWARDS ME.
