Verbatim excerpts from NHTSA complaints, by component

Power train

5 reports
“The valve body in the ten speed transmission failed while driving. The transmission did a rough shift and a message popped up on the display saying that power has been reduced along with the check engine light illuminating. The transmission reduced usable gears to prevent damage. I was a hazard on the road way due to not being able to get up to the posted speed limit. The car is at Harvey Cadillac (the dealership I purchased the car from) and I have been told GM is going to replace the transmission under warranty.”

Tires

2 reports1 crash
“Incident Overview: A Continental Control Contact Sport SRS+ tire (DOT 5323) experienced a catastrophic internal structural failure during normal driving on a wet roadway. The tire had approximately 50% tread remaining and was 1–1.5 years old. Failure Description: Inspection indicates internal belt/carcass separation originating within the tire structure, leading to rapid pressure loss and rupture. No road hazard or external impact was present. Crash Sequence: The failure caused immediate loss of control, vehicle yaw, roadway departure, and multiple impacts (frontal and lateral). The driver airbag deployed, confirming measurable crash force. Injuries: - Aggravation of pre-existing back condition (surgery required) - Hip labral tear and bone spur (surgery required) - Neck and shoulder pain Conclusion: The initiating event was a premature internal structural tire failure, not driver negligence or external hazard.”

Fuel/propulsion system

1 report
“While driving my 2023 Cadillac CT5-V Blackwing in an active traffic lane, the vehicle experienced a sudden and complete loss of propulsion. I was unable to maintain movement with traffic, and the vehicle became disabled in the roadway. The failure occurred without sufficient warning for me to safely remove the vehicle from active traffic. This created a serious safety hazard because the sudden loss of propulsion exposed me and other motorists to the risk of a rear-end or other collision. This incident is particularly concerning because the vehicle has experienced multiple catastrophic engine failures. The vehicle has experienced four engine failures and is currently at an authorized Cadillac dealership undergoing installation of a fifth engine. The vehicle previously spent approximately 157 days at an authorized Cadillac dealership during an extended repair period. Despite extensive repairs and engine replacement, the vehicle subsequently experienced additional engine failure. As of September 3, 2026, the vehicle remains at Suburban Cadillac of Plymouth and has not been returned to me. The current repair involves installation of another replacement engine. My…”
