A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single

TIRES
The contact owns a 2025 Cadillac XT4 equipped with Continental Tires, Tire Line: Pro Contact TX, Tire Size: 235/60/R18, DOT Number: (N/A). The contact stated that while driving at an undisclosed speed, the passenger’s side rear tires experienced a blowout. The vehicle was taken to the local dealer, where the tire was replaced, but six months later the driver’s side tire experienced a blowout, which caused significant damages to the driver’s side fender wheel well. The manufacturer was contacted but denied any financial assistance due to the purchase of the aftermarket tires. The contact replaced all four tires due to the concerns of another blowout. The approximate failure mileage was 9,114.

POWER TRAIN:AUTOMATIC TRANSMISSION
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.

SERVICE BRAKES
On July 28, 2025, while driving the vehicle on public street, a warning flashed that the brakes have failed. In fact the brakes were totally inoperative. Driver was able to clear traffic and exit the roadway without incident. The Cadillac dealership found no issue with the brakes, but did "update the brake control module." In March, 2026 a crack in the windshield appeared. Safelite Company was unable to replace the windshield, as their computer showed several modular errors, preventing them from recalibrating a new windshield. The car was taken to the local Cadillac Dealer, who was presented with a printout showing the following: Code U1961-92, "fail since clear. Code U164E-00, "fail since clear. Code U1605-00, "fail since clear", Code U1974-00, "fail since clear", U197A-00, "fail since clear", Code U1961-92 "fail since clear". The dealer reported that these error codes are no problem, and declined to take any action. They further advised that if a warning of any issue appears to bring the car in.

ELECTRICAL SYSTEM
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

VISIBILITY/WIPER
Since we purchased the vehicle, the Heads-Up display is too low, even in its highest adjusted setting. My wife is [XXX] and can only see part of the heads-up display. I am [XXX] ' tall and have to adjust the seat so far up that my head almost touches the roof to see the heads-up display on the highest setting. Dealership reports that no one else has reported the issue and will require taking the entire dash apart to diagnose. It is a safety hazard only being able to see part of the Heads-up display while driving and being so low in the windshield.
