The embedded navigation system in my 2018 GMC Sierra is no longer supported. Paid map updates were available until 2023, when General Motors discontinued them without notice. This system was marketed as a core feature and provided offline GPS guidance independent of cell reception. I discovered the change while attempting to purchase an update and was told there are no remaining copies and that no further updates will ever be made. I was never notified. When I contacted support, I was transferred through six departments. One representative admitted that customers were supposed to be informed but were not. She stated they are trained to say “there’s nothing we can do” and acknowledged receiving hundreds of similar complaints. She also confirmed the final map update existed but was allowed to sell out. This puts safety at risk, particularly for drivers in rural areas, areas with poor cell service, or while towing. The system is not CarPlay-based and does not rely on mobile data. It was the only in-vehicle routing system many drivers depended on during travel, including emergencies. Its quiet discontinuation means drivers no longer have access to accurate, integrated navigation—reducing their ability to safely plan or adjust routes while on the road. The failure to maintain this system or provide reasonable access to the final update undermines long-term vehicle safety and owner trust. General Motors has not offered an inspection, recovery, or remedy.

The amber light for being to close to another vehicle in front of you does not come on in the dash in my case less than half a truck length ahead. It does not have any sensors on front or rear because Dealer said it was because of lack of chips. There must be someway to adjust this for further notification then a half a truck length.

Informant system and instrument clust/panel starts to change with nothing be clicked. Starts to phantom change everything which is deters from paying attention to actual driving becoming a safety hazard. Dealership has tried to update the software and still does not work.

CLOCK AND OUTSIDE AIR TEMP READINGS ARE SO SMALL, YOU CAN'T SEE THEM, WITHOUT TAKING YOUR EYES OFF THE ROAD, LONG ENOUGH TO BEND OVER CLOSE TO THE RADIO. THIS IS AS BAD AS SOMEONE USING A CELL PHONE TO SEND AND RECEIVE TEXT. I HAVE DRIVEN OFF THE ROAD TWICE, BUT HAVE NOT CRASHED YET. MY GM DEALER SAYS, THE READINGS CAN NOT BE MADE LARGER, AND TO BE VERY CAREFUL.

THE BACKSEAT HEADRESTS DO NOT REMAIN IN THE UPRIGHT POSITION. THEY SLIDE DOWN WITH THE SLIGHTEST CONTACT FROM THE PERSON'S HEAD. THE MAINTENANCE/SERVICE PERSON AT THE DEALERSHIP INDICATED THAT THERE HAS BEEN NUMEROUS COMPLAINTS FROM OWNERS. HE INDICATED THAT AT THIS TIME IT IS A "NO FIX" PROBLEM. THIS IS UNACCEPTABLE AND DOES NOT MEET THE NATIONAL HIGHWAY TRAFFIC BOARDS REGULATIONS ON HEADREST EQUIPMENT. THIS IS A REAL SAFETY CONCERN. THE SERVICE DEPARTMENT INDICATED THAT A LATCH NEEDS TO BE INSTALLED TO HOLD THE HEADREST IN PLACE. IF THIS IS NOT CORRECTED, PEOPLE WILL AT SOME POINT IN TIME SUSTAIN SERIOUS INJURY. I FEEL LIKE CONTACTING 60 MINUTES WITH THE PROBLEM AND YOUR RESPONSE.

I PURCHASED 2 RUGGED RIDGE FRONT FLOOR MATS FOR MY 2009 GMC EXTENDED CAB 1500 SIERRA ON 11/15/13. LAST WEEK ON 1/9/14, I WAS ACCELERATING TO GET ON THE INTERSTATE AT FULL THROTTLE. THE ACCELERATOR STUCK DOWN AT FULL THROTTLE AFTER I LIGHTENED PEDDLE PRESSURE TO SLOW DOWN. AT FIRST I HIT THE BRAKES BUT COULDN'T SLOW THE VEHICLE. I THEN TURNED THE IGNITION KEY TO DISENGAGE THE IGNITION. THE TRUCK BEGAN TO SLOW. I TURNED THE IGNITION BACK ON AND THE TRUCK WAS STILL AT FULL THROTTLE AND I NEARLY REAR ENDED THE VEHICLE IN FRONT OF ME. I THEN PULLED THE FLOOR MAT BACK WITH MY HEEL AND THE ACCELERATOR RELEASED.
