What owners report
Total brake system failure. Lost almost all brake function nearly causing an accident. June 17, 2026 car was taken to dealership. Electronic Brake Control Module (EBCM), Brake Master Cylinder, Brake Pedal Retainer replacement required. August 7, 2026 received a call from dealer stating that EBCM replacement was faulty or failed. August 26, 2026 Contacted GM to ask for inclusion in recall 20V588000. Was refused inclusion. 70 days out of service and was forced to sell vehicle due to safety concern, extended repair schedule and cost of a vehicle I could not use. Two EBCM replacements and vehicle is still out of service as of August 26, 2026.
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.
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. I waited and in February it restarted without the engineer revving high. In April, it still revved high. When I took it to Ed Morse
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. The vehicle is at a GM dealership currently with all active codes and faulty equipment. I contacted GM and tried to get some help with this issue and they refuse to help since it
The vehicle shudders and loses power when accelerating fast. My wife almost got hit when she pulled out in traffic the car stalled out. It is due to the cylinder deactivation (afm).
