NHTSA Complaint #11718747 — 2026 GMC ACADIA

My wife and child drove the car to the grocery store and parked the car l. When she returned to leave , the car would not start and flashed a warning with key fob not detected and some kind of security light warning. The instrument cluster told her to place the key in left console cup holder to crank the vehicle . This did not work either .I drove the second key fob to her to determine if it was a key fob issue and the 2 nd key did not work as well. Called dealership and service requested the car being towed. Tow truck didn’t feel comfortable with the removing the vehicle as it was sitting due to space in the parking lot. They dispatched a small tow truck , but in the meantime I disconnected the battery cable and waited about 15 min. The car cranked and I immediately drove it to dealership. There was no code shown at the dealership and this was the first time they have had dealt with this issue. The mechanic drove the car the next day and the same situation happened again , except this time the key fob worked after several failed attempts . I feel that this is a safety issue because the car failed to operate and had no manual ability to operate without the electronic system functioning properly and this could have happened anyway and stranded my wife and child . A few months before in an unrelated incident , the power trunk malfunctioned and had to be reprogrammed . It would not operate except manually . Car is currently at dealership still being evaluated .
