Vehicle Safety Complaint I am submitting this complaint regarding my 2025 Cadillac XT4 because of a serious transmission failure that created a significant safety hazard. While driving on the interstate at approximately 60 mph, the transmission suddenly malfunctioned and the vehicle lost its ability to operate normally. The transmission appeared to disengage unexpectedly, causing a sudden loss of
... power and creating a dangerous situation in fast-moving traffic. I was concerned that my vehicle could have been struck by other vehicles because it was no longer responding as expected. The vehicle had to be towed to an authorized Cadillac dealership for inspection and repair. After diagnosing the problem, the dealership informed me that the entire transmission required replacement. This is a major component failure on a nearly new vehicle with relatively low mileage. A complete transmission replacement on a new vehicle, combined with a sudden failure at highway speed, raises serious concerns about the safety and reliability of this model. A transmission should not fail unexpectedly under normal driving conditions, especially in a new vehicle. (They changed gearbox in 14 days) I am reporting this incident because I believe it represents a potential safety defect that could place other drivers and passengers at risk. I respectfully request that NHTSA investigate whether similar transmission failures have been reported in the 2025 Cadillac XT4 and determine whether this issue warrants further investigation or a safety recall. In addition to the highway transmission failure, I have experienced another serious safety concern. When shifting the vehicle from Park into Drive or Reverse, the transmission sometimes does not engage immediately. Instead, there is a delay of several seconds, followed by a sudden and unexpected engagement that causes the vehicle to lunge forward or backward. This sudden movement is completely outside of my control and creates a significant safety risk.Read more
