Open the full vehicle complaint log (all categories)I AM 27 YEARS OLD FEMALE THAT WAS IN A CAR ACCIDENT WITH MY BOYFRIEND AND HIS MOM. MY BOYFRIENDS MOM WAS THE DRIVER, I WAS THE FRONT SEAT PASSENGER AND MY BOYFRIEND WAS IN THE BACK SEAT. BOTH MY BOYFRIENDS MOM AND I WERE WEARING OUR SEATBELTS. AFTER HANGING OUT FOR THE DAY MY BOYFRIENDS MOM WAS DROPPING US OFF AT HOME AND THAT WAS WHEN IT HAPPENED. AS SHE WAS BACKING UP OUT OF THE DRIVEWAY, THE ACCELERATOR MUST HAVE GOTTEN STUCK BECAUSE THE CAR FLEW ACROSS THE DRIVEWAY DOWN A HILL OVER A BASKETBALL COURT AND DIRECTLY INTO A TREE! THINKS THE VEHICLE WAS GOING 30-40 MPH AND BOTH FRONT AIRBAGS DEPLOYED. AFTER THE ACCIDENT I HAD BEEN INJURED AND AFTER GOING TO THE HOSPITAL AND HAVING X-RAYS DONE, THE DOCTORS HAVE SAID I HAVE A FRACTURE (L2) TO MY SPINE. THANK GOD NO SURGERY WAS NEEDED ALTHOUGH IT REALLY SUCKS TO HAVE A COMPRESSED VERTEBRA NOW! THE ACCIDENT HAPPENED ON JUNE 28, 2017 AND SINCE THE ACCIDENT I HAVE BEEN WEARING A LUMBAR BRACE IN ORDER TO HELP SUPPORT MY SPINE/BACK.
NOT LONG AFTER PURCHASING VEHICLE USED IT STARTED THIS LURCHING AND HESITATIONS IN MOVEMENT, THIS CAN ALSO BE OBSERVED (THE JUMPS AND HESITATIONS) IN RPMS ON THE TAC. THIS IS OCCURRING CONSISTENTLY PRIMARILY WHEN DRIVING BETWEEN 30-40 MPH; THIS DOES NOT STOP UNLESS YOU ACCELERATE QUICKLY OR ALLOW YOUR SPEED TO DROP BELOW 20 MPH
VEHICLE HESITATES WITH ACCELERATION AND DOES NOT MAINTAIN CONSTANT SPEED. WITH ACCELERATION, THE VEHICLE HESITATES AND THEN LURCHES SUDDENLY. THE VEHICLE FAILS TO MAINTAIN A CONSTANT VELOCITY, ESPECIALLY GOING UP A SLIGHT GRADE, MOST NOTICEABLY AT 35MPH AND 45MPH.
TL* THE CONTACT OWNS A 2014 ACURA MDX. WHILE DRIVING APPROXIMATELY 5 MPH, THE VEHICLE ACCELERATED INDEPENDENTLY AND CRASHED INTO A ROD IRON FENCE. THE AIR BAGS DID NOT DEPLOY. A POLICE REPORT WAS NOT FILED AND THERE WERE NO INJURIES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 44,323. THE VIN WAS NOT PROVIDED.
AS THE VEHICLE BEING DRIVEN, IT OCCASIONALLY LURCHES. AS THE VEHICLE PRODUCES THESE SUDDEN STOPS AND ACCELERATIONS DURING THE NORMAL DRIVING (LOCAL STREETS AND HIGHWAYS), I, AS A DRIVER, TEMPORARILY LOSE THE CONTROL OF THE CAR. CONSEQUENTLY, THIS CAR LURCHING SITUATION MAY LEAD TO THE DRIVER LOSING A TEMPORARY OR COMPLETE CONTROL OF THE VEHICLE WHICH COULD ULTIMATELY CAUSE A COLLISION.
RECENTLY FACED A SITUATION WHERE I WAS TRAVELING ON A FREEWAY @ 65-70 MPH AND SUDDENLY SUV FLASHED A FCW( FORWARD COLLISION WARNING SYSTEM) . I HAD TO APPLY THE BRAKES IN THE MIDDLE OF THE FREEWAY FEARING AN ACCIDENT. IT MAY HAVE CAUSED US TO TO GO INTO A CRASH WITH A CARS COMING FROM BEHIND . NHTSA HAS TO LOOK INTO THIS FEATURE. THERE IS SOME PROBLEM WITH THE SENSORS OF FCW

TL* THE CONTACT OWNS A 2014 ACURA MDX. UPON USING THE CRUISE CONTROL FEATURE, THE VEHICLE WOULD DECELERATE TO 20 MPH WHEN A LARGE VEHICLE PASSED BY. THE FAILURE OCCURRED MORE THAN THREE TIMES. THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 15V301000 (VEHICLE SPEED CONTROL). THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 18,000.
TRAVELING 65 MPH ON A FREEWAY WITH ADAPTIVE CRUISE CONTROL (ACC) ENGAGED, VEHICLE SUDDENLY BRAKES HARD ON ITS OWN FOR NO APPARENT REASON; DROPPING 10 MPH IN A HEARTBEAT. THE VEHICLE DID NOT PRODUCE A COLLISION WARNING MESSAGE ON THE DASH. THE CARS IN FRONT ON ME WERE WELL BEYOND THE LONGEST 4 BAR RANGE OF THE ACC SO IT WAS NOT DETECTING AND LOCKED ONTO A CAR IN FRONT OF ME. THERE WERE NO CARS ON EITHER SIDE, NO CAR CROSSING IN FRONT OF ME AND THE ROAD WAS FLAT WITH NO OBSTACLES. FORTUNATELY, THE CAR BEHIND ME WAS NOT TAILGATING AS THE SUDDEN DECELERATION COULD HAVE CAUSED A REAR END COLLISION. SUDDEN DECELERATION HAS HAPPENED TWICE DURING THE SIX WEEKS I'VE OWNED THIS VEHICLE. I'VE ALSO NOTICED THAT THE ACC IS INCONSISTENT, OFTEN SLUGGISH, IN RESPONDING TO THE SPEED OF TRAFFIC WHEN IT IS DETECTING A CAR IN FRONT OF ME; CREATING ADDITIONAL HAZARD CONCERNS FOR THE DRIVER. *TR..UPDATED 05-27-15 *BF UPDATED 8/28/2017*CN
OUR VEHICLE IS AN ACURA MDX 2014 WITH THE ADVANCE PACKAGE. ONE FEATURE OF THE PACKAGE IS ADAPTIVE CRUISE CONTROL WHICH AIMS TO KEEP THE VEHICLE MOVING AT A STEADY RATE AND AT A SET DISTANCE FROM ANY VEHICLE IN FRONT OF IT. ON SEVERAL OCCASIONS, WHEN VEHICLES IN FRONT OF OURS SLOWS DOWN OR A VEHICLE MERGES FROM ANOTHER LANE IN FRONT OF US (EVEN TRANSIENTLY), INSTEAD OF GRADUALLY BRAKING AND SPEEDING UP, THE ACURA PERFORMS SUDDEN DECELERATION WITH HARD BRAKING EVEN IF THE VEHICLE IN FRONT IS DOING THE SAME SPEED OR GOING ONLY SLIGHTLY SLOWER. AFTER THE HARD BRAKING STARTS, IF THE VEHICLE IN FRONT SPEEDS UP, OUR VEHICLE DOES NOT RECOVER AND START TO ACCELERATE AGAIN. I HAVE A PREGNANT WIFE WHO IS THE MAIN DRIVER OF THE CAR AND I AM CONCERNED THAT THIS PROBLEM WILL CAUSE HER TO BE REAR-ENDED. *TR
