What 447 owners told NHTSA about the 2014 GMC Acadia Denali

I have many problems with this vehicle, numerous times. Inaccurate Fuel Gauge Reading- It has resulted in my vehicle running out of fuel and stalling, while on road. I have 4 children who are at risk of danger while in vehicle.The fuel warning light has illuminated when the gauge needle says I still have more than plenty of amount (a quarter of a tank or more at times. It differs). It was diagnosed with an electrical and fuel system failure. Electrical shorts and problems- Having electrical shorts on and off. Check engine light comes on/off Vehicle randomly failed to start. My vehicle was difficult to start and would require several attempts before starting. Power lock/unlock key fob doesn't work, replaced battery multiple times.windows and sunroof power windows do no work. Radio and dash turn off and restart. Check airbag light has been coming on and off. Power Train intermittently, the transmission shifts with a loud thump, at various speeds. Vehicle starts shaking and jerking while shifting gears and going different speeds. My vehicle slows down, power reduce engine and steering difficult at times. Other/ water leak- Found water in all of my tail light assemblies, headlight assemblies, sunroof and windows leaking. There is no proper seal or has worn off, causing leaks in and repairs for many replacements, which are expensive temp fixes with no permanent solution. Causes accidents by not having necessary working equipment for driving conditions. Other:Hood doesn't latch and stay open so difficult to even check fluids properly alone. Multiple dealers have inspected problems, and needs to be fixed. There are recalls out for many of these problems and my vehicle needs to be on the list for serious safety issues.

Low beams randomly stopped working. All other lights work.

I have 2 concerns and issues with my vehicle. 1st is the rear turn signal bulb and housing, I have read forums and researched the issue and many others have had the same issues and concerns, water is getting into the housing and is causing the bulb to blow and can possibly be causing fire/electrical with the wiring. 2nd is the front headlights the plastic round covering that's in surrounding the the glass that the light sits behind is melting and is causing visibility issues as well as potential fire. I can imagine why the plastic would be installed so close to a glass covering that holds heat. I really think that GMC needs to evaluate these concerns not only for safety but also the expense of the turn signal bulb that has been designed and cost over $100 because it couldn't be a simple bulb like most others. Also I have been informed of a recall of the airbag and can't get it fixed because the dealerships haven't been sent the part! I would like to be notified that someone has aknowledged my concern. Thanks

I noticed headlights not working low or high beam. LED lights around head lights worked and fog lights but no headlights. I normally keep it on auto, but I tried all positions and none of them worked.

Head lights quit working. I had two children in the car with me and it was night time, and I could’ve collided with another car. This just happened tonight, so I have not taken it to the dealer yet or a certified mechanic. There were no warnings of any kind before this happened.

My left rear turn signal is not working. It is GM part number 13582912. I have checked with several GM dealers who have. Confirmed there are none available. Just for the sake of it, 3 dealers have it on order but have no confirmed delivery date. Some parts stores say it’s is discontinued. There are no other aftermarket parts to substitute. This is a significant safety issue the GM needs to correct.

Tail lights/brakes light/blinkers The light kit cover seals break allowing water into the light kit. Water collects and shorts out the bulbs causing a dangerous hazard when rear lights fail to work in the proper manner. I have called to several places and am being told, yes, GMC has a defect on their rear tail lights. Seals were not done very well and supply cannot keep up with demand. The lights are over 300 each which is absolutely ridiculous. A part that is necessary to keep one safe and be able to signal to other drivers should not be this expensive when the manufacturer did not build a good product.

SERVICE SIDE BLIND DETECTION STARTED GOING OFF THEN THE SIDE BLIND DETECTION STOPPED WORKING COMPLETELY. NOW THE ENTIRE ELECTRICAL SYSTEM IS NOT WORKING CORRECTLY AND WAS TOLD THE SIDE BLIND DETECTION MONITORS CAN CAUSE THE ENTIRE ELECTRICAL SYSTEM TO MALFUNCTION.

CAR SHUT OFF WHILE DRIVING. ALL ELECTRICAL WENT OUT. DOORS ALL LOCKED WHILE INSIDE, KEY STUCK IN IGNITION. STARTED WITH SIDE DETECTION WARNING AND WITHIN A FEW DAYS CAR COMPLETELY SHUT OFF WHILE DRIVING! HUGE SAFETY ISSUE! WILL NOT RESTART AND STILL CAN'T GET KEY OUT OF THE IGNITION. BATTERY IS FULLY CHARGED BUT NO POWER. COMPLETELY DEAD. THERE IS A KNOWN RECALL ON 2014 GMC ACADIAS FOR ELECTRONIC MODULE FAILURE BUT NOT OUR SPECIFIC VEHICLE THOUGH THIS SEEMS TO BE THE EXACT CAUSE OF OUR PROBLEMS. GMC SAID THEY COULD NOT HELP?!

MY HEADLIGHTS STOPPED WORKING WHILE I WAS DRIVING ON A HIGHWAY. I PULLED OFF THE ROAD & THE DRL LED LIGHTS AROUND THE HEADLIGHTS WERE STILL ON, BUT THE HEADLIGHTS WERE NOT. I TRIED TURNING THE LIGHTS OFF/ON, TRIED TURNING THE VEHICLE OFF/ON. MY HUSBAND CHECKED THE FUSES, RELAY, & SENSORS, AS WELL AS CHANGED BOTH BULBS AND THEY STILL WILL NOT WORK. IT WAS DARK WHILE I WAS DRIVING, WHICH POSED A DANGEROUS SITUATION. UPON RESEARCHING ONLINE, THERE SEEMS TO BE OTHER PEOPLE WHO HAVE HAD THE SAME PROBLEM.

BOUGHT CAR BRAND NEW 8-14. SINCE I HAVE TAKEN INTO DEALERSHIP OVER 5 TIMES REGARDING IT STALLING, AND COMPLETE SHUT DOWN WHILE DRIVING. FIRST CAR WOULD SHUT OFF WHEN IN REVERSE. CAR TURNED OFF COMPLETELY MULTIPLE TIMES SITTING AT RED LIGHTS. THEN WHILE I WAS DRIVING 35 MILES ON RESIDENTIAL STREET I HAD COMPLETE FAILURE, CAR TURNED OFF. WAS ABLE TO RESTART AND DRIVE. CAR TAKES A COUPLE SECONDS TO TURN OVER WHEN FIRST PUTTING KEY IN. NOTICED RECALL IN 10-14 FOR EXACT ISSUE BUT GMC DEALER IN CONCORD CA SAYS MY CAR IS NOT INCLUDED IN IT. INTERIOR LIGHTS GO ON AT RANDOM ALONG WITH HEADLIGHTS. GAS GAUGE IN "MILES" READING ON DASH LOWERS BY 20+ MILES EACH TIME I DROP KIDS OFF AT SCHOOL 5 MILES AWAY. EACH TIME I HAVE TAKEN IT TO DEALER, DEALER STATED THEY ARE UNABLE TO DUPLICATE THE EVENTS, NO WARNING CODES ARE SHOWING AND THEY CAN NOT FIND WHAT'S WRONG WITH THE CAR. SHOCKER. BRAND NEW CARS DO NOT OPERATE THIS WAY AND THESE ISSUES ARE VERY SERIOUS AS DEATHS COULD OCCUR WHEN CAR SHUTS DOWN WHILE DRIVING. TAKING IT TO DEALER AGAIN.

2014 GMC ACADIA HEADLIGHTS DO NOT SHINE OUT FAR ENOUGH TO SEE THE ROAD AHEAD OR TO EACH SIDE WHEN TURNING. I FEEL LIKE I HAVE A DARK HOOD OVER THE TOP PART OF MY EYES AND THIS HOOD "BOUNCES" AS YOU TRAVEL--VERY DISTRACTING, IRRITATING, AND UNSAFE. WHEN DRIVING AT NIGHT, I ALWAYS HAVE MY FOG LIGHTS ON, BUT EVEN THAT DOES NOT HELP MUCH. WHEN DRIVING ON A HILLY, CURVY ROAD, IT IS IMPOSSIBLE TO SEE THE ROAD AHEAD & SIDES--SCARES THE HECK OUT OF ME! I LOVE THIS ACADIA, BUT REFUSE TO DRIVE IT ON A TRIP WHEN I KNOW I WILL BE DRIVING AT NIGHT AND WOULD BE SCARED TO DEATH IF IT WOULD RAIN AT NIGHT--SO WE TAKE OUR OTHER VEHICLE ON MOST TRIPS. I HAVE FOUND OTHER COMPLAINTS ABOUT THE ACADIA HEADLIGHTS FOR THE 2013 AND 2015 MODELS. ALSO FOUND MANY COMPLAINTS ABOUT THE 2014 GMC SIERRA 1500 PICKUPS THAT SOUND JUST LIKE MY CONCERNS. I HAVE COMPLAINED TO OUR LOCAL DEALERSHIP A COUPLE TIMES AND WILL CONTINUE TO DO SO. SURELY GMC WILL WAKE UP AND REALIZE THAT THESE HEADLIGHTS CREATE DANGEROUS NIGHTTIME DRIVING CONDITIONS. THIS IS A SAFETY ISSUE THAT NEEDS TO BE ADDRESSED!

TWO SEPARATE WARRANTY CLAIMS. DEALER DID REPLACE ALL TAIL LIGHT ASSEMBLIES- ONCE ON NORMAL WARRANTY CLAIM, THE SECOND INCIDENT (LHS ONLY) ON CUSTOMER SATISFACTION BASIS. ISSUE> REAR TAIL LIGHT LENS CLOUDS UP WITH CONDENSATION / WATER TO THE POINT THAT STOP LIGHT VISIBILITY IS AFFECTED. APPROX 50% OF THE LENS IS COVERED INTERNALLY WITH WATER DROPLETS AND CONDENSATION POTENTIALLY VIOLATING FMVSS SAFETY STANDARD FOR VISIBILITY. APPARENTLY THE LAMP ASSEMBLY IS NOT SEALED AND PERMITS WATER INTRUSION. CONDENSATION DOES NOT CLEAR UP ADEQUATELY- IN MY CASE AFTER 16 MILES OF DRIVING OR LEAVING THE SUV OUTSIDE OVERNIGHT. RESPONSE FROM DEALER: GM ISSUED A LETTER STATING WARRANTY CLAIMS WILL NOT BE HONORED FOR WATER CONDENSATION ON TAIL LIGHT LENS. *TR
