2018 Cadillac XT5 Brakes Problems

Brakes failure. Approaching a busy intersection and facing a red light, I slowed and prepared to stop the vehicle. Nothing happened with regard to braking; instead, the engine seemed to rev up as it continued through the red-lighted intersection with 2 lanes of busy cross traffic from both directions. That there was not a collision is a miracle. I also noticed some flashing displays on the display screen, though hard to take time to read them while avoiding a crash and still trying to stop the car, but I believe they referenced "parking assist." My husband came and drove the car to the dealership (about 3 mi.), and during that drive, there was no braking issue but a Parking Assist readout suddenly appeared, and he was able to return the screen to the map; then a few minutes later, while driving under 20 mph near the dealership there was a notice about "maximum speed" being reached and "parking assist" being somehow reactivated. Vehicle currently at dealership for analysis. Side note: this is our second Cadillac to exhibit this problem -- there should be an NHTSA report on the first (April 2025) -- a 2013 SRX, in which there was a parking lot collision that totaled the vehicle.

I was having some routine maintenance done on my car and a popping sound was heard around and under the front of my car. The the car displays a break light in the display and the fault code C056E is now constantly present in the computer. My vehicle is not showing a recall but I know this problem. Is a recall on other similar year and models.

The contact owns a 2018 Cadillac XT5. The contact stated that while driving at an undisclosed speed, the driver's and passenger's rear wheels locked up, causing the driver's and passenger's rear tires to roll backwards. The contact stated that the ABS failed to operate as intended. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was unknown.

TWO ISSUES INVOLVING THE BRAKES. FRONT BRAKE PADS SQUEAK WHEN MOVING SLOWLY, ESPECIALLY IN THE MORNING OR WHEN MOVING IN A DRIVE THROUGH LINE. THE SECOND IS THE BRAKE PEDAL LOSES PRESSURE OVER NIGHT OR EXTENDED PERIODS OF NON-USE. IT DOES NOT OCCUR EVERY NIGHT. BRAKE PEDAL IS DIFFICULT TO PUSH TO START THE CAR.

PARKED IN PUBLIC PARKING LOT. AFTER STARTING CAR AND ATTEMPTING TO BACKUP, CAR WOULD NOT MOVE. PARKING BRAKES WERE LOCKED. TRIED NUMEROUS TIMES TO RELEASE BRAKES. PARKING BRAKE WOULD NOT RELEASE. CAR WOULD NOT MOVE FORWARD OR BACKWARDS. HAD SAME ISSUE WITH 2013/XTS AND 2014/XTS BUT TURNING CAR ON/OFF WOULD RELEASE BRAKES ON THOSE CARS. THIS TIME, HAD TO CALL TOW TRUCK. WEATHER SUNNY, TEMPERATURE 33F. CAR JUST RECENTLY RECEIVED MILEAGE MAINTENANCE. WARRANTY SERVICE FOR BRAKES TWICE SINCE PURCHASING THE CAR.

I TOOK MY CADILLAC XT5 2018 IN FOR SERVICE TODAY 07/23/2019 FOR AN OIL CHANGE AND BRAKE CHECK AS THE BRAKES ARE SQUEALING. I WAS TOLD THEY WEREN'T GOING TO HAVE TIME TO WORK ON THE BRAKES BUT THAT "THE SOUND IS NORMAL DUE TO THE MATERIALS THAT GM USES. THAT THEY WOULD'VE ONLY LUBRICATED THE DISKS BUT THE NOISE WOULD'VE CAME BACK IN A WEEK OR 2". I TOOK IT IN BEFORE FOR THE SAME PROBLEM AND WHEN I RECEIVED A CALL LETTING ME KNOW THE SERVICES HAD BEEN COMPLETED, THE SERVICE AGENT INFORMED ME THAT IT WAS A PROBLEM THAT WAS HAPPENING A LOT WITH THE 2018 XT5 MODELS. AT THAT TIME, HE THEN TOLD ME THE NOISE SHOULD BE GONE FOR GOOD. THE NOISE WAS ONLY GONE FOR A COUPLE MONTHS AND IT CAME BACK. I HAVE NOT OWNED THE VEHICLE FOR EVEN 1 YEAR. I AM BEGINNING TO FEAR FOR MY SAFETY AS I DON'T REALLY KNOW WHAT TO BELIEVE ANYMORE AS I HAVE GOTTEN 2 DIFFERENT STORIES AND I DRIVE MY DAUGHTER WITH ME ALL THE TIME.
