2017 Acura MDX Sport Hybrid SUV AWD

VEHICLE INTERMITTENTLY BREAKS DOWN WITH "POWER SYSTEM" AND "AWD" WARNING LIGHTS TRIGGERING SAFE MODE OPERATION. SAFE MODE LIMITS POWER AND POTENTIALLY CREATES UNSAFE CONDITION AS CAR CANNOT BE OPERATED AT FULL POWER. ACURA REFUSES TO REPAIR. PROBLEM OCCURS BOTH WITH IN MOTION AND WHEN AT IDLE.

UNINTENDED ACCELERATION - WHILE COASTING, THE VEHICLE ACCELERATES ON ITS OWN UP TO 30MPH. THIS HAS OCCURRED WHILE APPROACHING TRAFFIC LIGHTS, STOP SIGNS, PARKING LOTS, CROSSWALKS AND PARKING IN THE GARAGE. THIS HAS HAPPENED ON SEVERAL OCCASIONS WITH TWO DIFFERENT DRIVERS AND EVEN THE DEALER HAS EXPERIENCED THE SAME SYMPTOMS. THE VEHICLE ALSO STALLS WHILE STOPPED IN THE ROADWAY TO TURN. ACURA SENT A REGIONAL SERVICE DIRECTOR TO TEST THE VEHICLE AND MY DRIVING SKILLS AND STATES THAT SINCE THERE ARE NO TROUBLE CODES FROM THE COMPUTER, ALL SYSTEMS ARE OPERATING AS DESIGNED. BRAKING - THE ADAPTIVE CRUISE CONTROL WILL SENSE LARGE VEHICLES IN ADJACENT LANES AND SMALL VEHICLES ON CURVES AND ABRUPTLY APPLY BRAKES. THE VEHICLE BELIEVES THESE VEHICLES ARE IN OUR LANE WHEN THEY ARE IN FACT IN THE ADJACENT LANE. WE HAVE HAD SEVERAL NEAR MISSES WHERE THE VEHICLE BEHIND US ALMOST REAR ENDED US DUE TO THE IMMEDIATE AND UNNECESSARY APPLICATION OF THE BRAKES. WE HAVE NO CONFIDENCE IN THIS VEHICLES TECHNOLOGY TO PERFORM AS INTENDED AND FEAR EVENTUALLY SOMEONE WILL BE HURT OR KILLED AS IT DOES NOT RECOGNIZE PEDESTRIANS EITHER.

THIS CAR HAS SERIOUS ISSUES. THE PREVIOUS BRAKING COMPLAINT IS ABSOLUTELY VALID! THE FIRST TWO ISSUES OUTLINED BELOW ARE MOST PROBLEMATIC AT HIGHWAY SPEED WITH THE ADAPTIVE CRUISE CONTROL SET. THAT BEING SAID, PROBLEM NUMBER ONE IN PARTICULAR OCCURS ON A REGULAR BASIS WHENEVER THE CRUISE CONTROL IS SET. 1. BRAKING - THE ADAPTIVE CRUISE CONTROL WILL SENSE LARGE VEHICLES IN ADJACENT LANES AND ABRUPTLY APPLY BRAKES. IT SEEMS THE MDX 'THINKS' THESE VEHICLES ARE IN YOUR LANE WHEN THEY ARE IN FACT IN THE LANE NEXT TO YOU. THE SAME WILL OCCUR WHEN A CAR IN AN ADJACENT LANE DRIFTS NEAR, BUT NOT INTO THE LANE OCCUPIED BY THE MDX. WE HAVE HAD NO LESS THAN THREE NEAR MISSES WHERE THE VEHICLE BEHIND US NEARLY REAR ENDED US DUE TO THE IMMEDIATE AND UNNECESSARY APPLICATION OF BRAKES BY THE MDX. 2. LANE KEEP ASSIST - ON A MULTIPLE OCCASIONS WE HAVE ATTEMPTED TO MANEUVER THE VEHICLE WHILE REMAINING IN OUR LANE TO AVOID A ROAD HAZARD. THE CAR FIGHTS AGAINST YOU WITH SUCH FORCE AS TO NEARLY MAKE THE VEHICLE NON-MANEUVERABLE. BOTH OF THE ITEMS ABOVE HAVE BEEN REPORTED TO THE DEALER TWICE. IN BOTH CASES WE WERE TOLD THIS IS NORMAL AND THAT WE SHOULD ADJUST THE SENSOR SENSITIVITY. WE'VE TRIED ALL LEVELS OF THE SENSOR SENSITIVITY AND NOTHING HAS WORKED. 3. UNINTENDED ACCELERATION - THIS IS EASILY THE MOST SCARY THING THAT HAS OCCURRED. WHILE SLOWLY DRIVING THROUGH A GROCERY STORE PARKING LOT, MY FOOT WAS HOVERING OVER THE BRAKE. OUR MDX ALL OF A SUDDEN WITH NO DRIVER INPUT AUTOMATICALLY ACCELERATED ABRUPTLY. I IMMEDIATELY HIT THE BRAKES AND THE VEHICLE RESPONDED. THANKFULLY, NO PEDESTRIAN WAS CROSSING IN FRONT OF ME. I'VE YET TO SEE THIS PROBLEM AGAIN HOWEVER THIS CAUSES SERIOUS CONCERN.
