“The X50A underhood fuse block (passenger side, near battery) has melted through at terminal 51 / run crank relay location. Plastic housing is burned through with charred bus bars and melted connector underneath, next to main battery cable. Vehicle first showed "Service Stabilitrak," "Service Traction Control," and "Engine Power Reduced," then went to crank-no-start condition requiring repeated jump starts to move. Codes P1682 and P0689 present. Each jump causes more heating at melted area. This is documented defect in GM TSB 19NA276 and PIT5406C for loose terminals causing arcing and thermal damage in 2013-2017 Buick Enclave, Chevy Traverse, GMC Acadia. Vehicle is primary family vehicle used daily to transport 6 children. Failure caused loss of power and no-start while responsible for 6 children, creating unsafe stranding and fire risk with children in vehicle. Vehicle is now parked with battery disconnected due to fire concern. Request investigation for recall for X50A thermal events.”

“I purchased this used 2016 Buick Enclave in July 2026. Shortly after purchase, the vehicle began repeatedly jerking and hesitating while driving. During occurrences, Traction Control/StabiliTrak warnings appeared and the vehicle experienced loss of power and difficulty accelerating normally. I reported the jerking/drivability problem to the selling dealer. On July 27, 2026, the selling dealer attempted a repair after I reported the jerking/drivability problem. Within approximately five minutes of leaving the dealership, the vehicle began jerking again. I then took the vehicle to an auto-parts store, where an OBD-II scan produced multiple diagnostic trouble codes, including P0300 engine misfire and several MAP-sensor-related codes. I have photographs documenting the scan results. The vehicle became disabled shortly thereafter and required towing. It was subsequently evaluated by an independent repair facility, where the MAP sensor was replaced. The vehicle later again experienced the jerking/loss-of-power condition and StabiliTrak/Traction Control warnings. On August 10, the vehicle became disabled again. These incidents have occurred while driving in traffic.…”
