This vehicle has had an intermittent (for a few years) issue with all of the warning lights (ABS,Stabilitrak,Parking Brake,Steering) coming on when starting. If you tried to drive it, you would have no power steering causing the vehicle difficult to handle. This would not happen every time it was started. We took the car to the local Cadillac dealership and were told nothing was wrong and it was just the system going through the electronic check system and to just not put it in gear until after the lights cleared. That actually did work sometimes. Recently, it came off and would never go off. We took it to a shop that does other work on other vehicles for me. He found that the Electronic Brake Control Module was bad. He tried to source a replacement one but found that it was discontinued with no alternate part. …
2015 Cadillac SRX with 87,397 has a failed Electronic Brake Control Module (EBCM) or ABS module. It can be made available for inspection upon request. Alexander Cadillac of Oxnard refuses to repair it stating a replacement part is no longer available (it can be repaired by a specialty repair company). They cite liability by using after market or repaired parts. Without a functioning EBCM - ABS,power steering and traction control do not work which puts me and others at risk. Worse, the failed EBCM is now causing the car to go into "limp mode", which cuts power to the engine and prevent acceleration. When making a turn onto a street, it suddenly went into limp mode and I was almost hit by an approaching semi-truck. The problem was identified by Alexander of Oxnard service center - but they refuse to make any effort to remedy the problem. …

My Cadillac has had and currently has a cracked spider web screen where you control the vehicles settings, GPS, Temperature for the car and so forth. Due to this I have lost any control to these settings since the cracked screen has caused the touchscreen to not even work and there is no response when you tap the screen. Have reached out to Cadillac and they say it's not their problem but the screen was not cracked in any kind of accident it was cracked due to the way Cadillac built the screen and the type of materials used to build the screen. Multiple people have had the same issue and Cadillac refuses to recall the touchscreen on these vehicles.
I am filing a formal complaint with Cadillac and the NTSB about the design of the 2015 Cadillac SRX sunroof drains and rear hatch. The issue is that the rear sunroof drains get clogged and water fills the rear compartment and destroys the rear hatch electronics. Further, there is no manual release on the rear hatch which creates a safety hazard as there is no access to the spare tire. The repairs are estimated at $3,091.09 as shown on the attached quote and diagnostic receipt.
The CUE touchscreen display has cracked for the second time in seven years without any physical impact. This appears to be a widespread defect in Cadillac SRX models. The screen becomes unresponsive and is a major distraction while driving, impacting safety, navigation, climate control, and backup camera visibility. Cadillac previously replaced it under warranty, but it has failed again. GM has not issued a recall despite hundreds of similar reports."
