NHTSA Complaint #11713151 — 2025 CADILLAC XT4

The vehicle’s OnStar system, emergency calling features, and built-in navigation/maps do not function properly. The maps do not work, emergency calling is unreliable, and OnStar is unable to accurately locate my vehicle. This is a serious safety concern because these systems are intended to provide immediate emergency assistance and precise location information. I am the primary caregiver for my minor son, who has significant medical conditions like heart failure and requires ongoing cardiac care. In the event of a medical emergency while driving with him, it is critical that emergency services be able to locate us immediately and accurately. Because the vehicle cannot reliably provide location data or emergency communication, emergency responders may not be able to find us if assistance is needed. This creates a dangerous situation and defeats the purpose of the vehicle’s safety systems. The failure of these features makes the vehicle unsafe for transporting my child, and I do not feel safe driving it. The issue appears to involve the vehicle’s communication, software, or electrical systems and remains unresolved despite being reported. The vehicle displayed a dashboard warning stating “Service Emergency Calling,” indicating a failure of the emergency communication system. This warning confirms the emergency calling feature is not operating as designed At this moment the part is on backorder till i don’t know when
