Example complaints

Engine: “69,000 mile oil change I was told i needed to spend thousands of dollars on repairing an oil leak b/c my Cam carrier is leaking. Cadillac has a know issue with this repair and refuses to stand behind it's product. Numerous complaints already on forums and yet they charge thousands to fix. A top name brand that can't produce a vehicle past 69000 miles without a major issue. I wanted to make it known about the ongoing issue by Cadillac. So sad.”

NHTSA complaint #11759557, filed 2026-08

Brakes: “The electronic brake control module, break retainer, brake master cylinder and brake valve all failed. I was driving to lunch and coming down a hill when multiple warning lights turned on as I pressed the brakes. I had almost no braking power as I approached a stop sign that lets you enter a highway almost causing me to drive through the stop sign and into cross traffic. I had enough bearings to down shift it and slow it down enough to stop. If I have went through the stop sign, it could have been a fatal accident. …”

NHTSA complaint #11745985, filed 2026-06

Transmission and drivetrain: “I had two incidents with the Cadillac CT-4 in February and then again in April of 2026 of driving on I-75 at a highway speed of about 70 MPH when the vehicle suddenly downshifted and the engine revving at at very high RPM. The vehicle slowed down suddenly and it felt for a moment that I could not control the speed. The check engine light was on and the diagnostic indicated a transmission/engineer problem and to take in to service within a day. Both incidents in February and April felt the same. Both times I pulled over to the shoulder to shut the engine. …”
