2017 GMC Acadia

ON 2017 ACADIA WITH IT'S 6TXX TRANSMISSION, THE SHIFTS FROM 2-3 FEEL WEIRD (ESPECIALLY) WHEN DRIVING AT SLOW SPEEDS. YOU GET A FEELING AS IF TRANNY TAKES MORE THAN USUAL TIME TO ENGAGE INTO 3RD GEAR, WHEN ALREADY DISENGAGED FROM 2ND GEAR. THIS IS SIMILAR TO WHAT FEELING ONE MIGHT GET IF YOU MOVED FROM 2ND - NEUTRAL - 3RD GEAR. I STARTED EXPERIENCING THIS ISSUE FROM APPROX. 5K MILES. THIS WOULD BE RISKY WHEN YOU ARE TRYING TO MERGE INTO A YIELD OR CHANGE LANES AND THIS SHIFT OCCURS, YOU MOMENTARILY FEEL LOSS OF CONTROL. A QUICK GOOGLE SEARCH ON THIS ISSUE AND YOU WILL SEE FOLKS ALREADY COMPLAINING ABOUT THIS ON FORUMS. *TR

LOW BEAM HEADLIGHT PERFORMANCE INADEQUATE. VERTICAL AIM IS OK BUT LUMINOUS LUX IS LOW, AND LATERAL COVERAGE DURING LOW SPEED TURNING IS INSUFFICIENT. IF THIS VEHICLE MEETS THE FMVSS STANDARD FOR LIGHTING, CONSIDER RAISING THE MINIMUM STANDARDS. LIGHTING IS A SAFETY ISSUE NHTSA NOW TESTS FOR. UNLESS THE CUSTOMER DOES A TEST DRIVE AT NIGHT (CAN BE IMPOSSIBLE DURING THE SUMMER), THERE IS NO WAY TO LEARN OF A DEFICIENCY BEFORE PURCHASING.

ON A RECENT TRIP. GOING 70 MPH ON THE HIGHWAY, 28 DEGREES OUTSIDE. WE CONSTANTLY HAD TO KEEP TURNING DOWN THE INSIDE TEMP. STARTED AT 72 DEGREES INSIDE AND FINALLY GOT TO A COMFORTABLE INSIDE TEMP AT 66 OR 67 DEGREES. ANYTHING ABOVE THAT WAS WAY TO HOT. WHEN YOU STOPPED OR SLOWED WAY DOWN, THE TEMP HAD TO BE TURNED UP. THIS IS WHILE THE SYSTEM WAS SET TO AUTO. THIS COULD CAUSE THE DRIVER TO TAKE THERE EYES OFF OF THE ROAD TO MESS WITH THE CLIMATE CONTROL.

2017 ACADIA 'DENALI' TRIM IS MISSING AFM INFORMATION FROM ITS DIC DISPLAY. AFM INFORMATION SHOWS WHEN THE ENGINE IS USING 6 V/S 4 CYLINDERS. OTHER TRIMS SEEM TO SHOW AFM INFORMATION WHEN EQUIPPED WITH V6 ENGINE. AFM IS AN IMPORTANT FEATURE AND DENALI BEING THE HIGHEST LEVEL TRIM SHOULD DEFINITELY HAVE THIS INFORMATION AVAILABLE. GM SHOULD PROVIDE UPGRADED DISPLAY TO 2017 DENALI CUSTOMERS.

ADAPTIVE-CRUISE-CONTROL (ACC)/FORWARD COLLISION BRAKING(AVOIDANCE) SYSTEM APPLIED VERY STRONG BRAKES(TWICE) IN CERTAIN SCENARIO WHEN USING ACC, INCREASING THE CHANCES OF VEHICLE BEHIND REAR-ENDING. WHILE ACC IS ENABLED, SAY YOUR VEHICLE COMES TO FULLSTOP AS VEHICLE IN FRONT HAS COME TO A FULL STOP(SAY AT TRAFFIC SIGNAL) AND ACC APPLIES FULL BRAKES. TRAFFIC AHEAD STARTS MOVING AGAIN, BUT SINCE VEHICLE WON'T MOVE ON ITS OWN DRIVER IS REQUIRED TO PRESS ACCELERATOR TO GET IT MOVING AGAIN OR ACC TO RESUME ITS OPERATION (THIS IS BY DESIGN). IN SUCH SCENARIO IF DRIVER ENDS UP PUSHING ACCELERATOR A BIT HARDER(I.E. MORE THAN JUST TAPPING IT), ACC APPLIES VERY STRONG BRAKES STOPPING VEHICLE RIGHT THERE. BY THIS TIME VEHICLE BEHIND YOU HAS STARTED MOVING ALREADY AND MIGHT REAR-END DUE TO ABRUPT STOP. I GUESS ACC THINKS DISTANCE BETWEEN YOU AND VEHICLE AHEAD IS VERY LESS AND THINKS ITS GOING TO COLLIDE AND HENCE APPLIES STRONG BRAKES. BUT THIS IS A BAD DESIGN/PROGRAMMING SINCE IT EXPECTS DRIVER TO PUSH ACC. PEDAL FOR ACC TO RESUME OPERATIONS, BUT IF DRIVER DOES IT BIT MORE THAN WHAT ACC LIKES, THERE IS A CHANCE OF ACCIDENT. GM SHOULD PERFORM MORE TESTS WITH ITS ACC AROUND SUCH SCENARIOS AND FINE-TUNE THEIR ACC SOFTWARE. *TR
