2017 Cadillac XT5 Brakes Problems

The thermostat has malfunctioned twice in 2 years. Driving vehicle and dash warning" STEERING ASSIST IS REDUCED DRIVE WITH CARE", also the temperature gauge was showing COLD and this was after driving for over 30 minutes. Contacted local dealer and was informed this is a KNOWN problem with the thermostat sticking open. My brakes are sticking often and my car often jumps hard when i put it in reverse.

The contact owns a 2017 Cadillac XT5. The contact stated that the rear passenger's side brake line was fractured. The vehicle was taken to the dealer where it was diagnosed that the rear passenger's side brake line needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 66,000.

ON MARCH 23 WE TOOK OUR 2017 CADILLAC XT5 TO THE DEALERSHIP FOR A SERVICE BECAUSE 2 DAYS PRIOR, THE PARKING BRAKE WOULD NOT RELEASE WHILE IN A STATIONARY POSITION. WE WERE ABLE TO RELEASE THE PARKING BRAKE AFTER TURNING THE VEHICLE ON AND OFF MULTIPLE TIMES. ALL OF THE WARNING LIGHTS ON THE DASH CAME ON, BUT THE BRAKE RELEASED AND WAS ABLE TO BE DRIVEN HOME. THE VEHICLE WAS READY TO BE PICKED UP THE FOLLOWING DAY. THEY HAD REPLACED THE PARKING BRAKE ACTUATOR AND STATED THAT IT WAS THE CAUSE OF THE ISSUE. THE VEHICLE SEEMED TO BE RUNNING NORMALLY FOR US AND CONTINUED TO DO SO UNTIL THE MORNING OF APRIL 9TH. MY WIFE WAS JUST LEAVING WORK THAT MORNING AND STARTED DRIVING THE CAR HOME WHEN SHE APPROACHED A STOP LIGHT AND THE BRAKE PEDAL WENT TO THE FLOOR, THE VEHICLE WAS NOT ABLE TO BE SLOWED OR STOPPED. SHE WAS ABLE TO SAFELY GO THROUGH THE RED LIGHT AND TURN INTO A PARKING LOT WHERE THE VEHICLE ROLLED INTO A PARKING STALL. IF SHE HAD MADE IT THROUGH THE LIGHT ON GREEN, SHE WOULD HAVE BEEN ON THE FREEWAY. THERE WAS A GRAND TOTAL OF 108 ADDITIONAL MILES SINCE THE LAST SERVICE ON MARCH 23. THE VEHICLE WAS TOWED BACK TO THE DEALERSHIP WHERE THEY HAD IT FOR ALMOST A WEEK. THEY FOUND THAT THE MASTER CYLINDER HAD BEEN LEAKING INTO THE BOOSTER WHICH CAUSED THE FAIL. THE BRAKE BOOSTER AND MASTER CYLINDER WERE BOTH REPLACED. AFTER ADDITIONAL RESEARCH, I HAVE FOUND MULTIPLE PEOPLE HAVE HAD THE SAME/SIMILAR ISSUES WITH THEIR VEHICLE. IT APPEARS THAT ALL OF THE WARNING LIGHTS COMING ON AT THE SAME TIME MAY HAVE BEEN A SIGN THAT THE MASTER CYLINDER WAS FAILING. *TR

SQUEAKY BRAKES. DEALER SAYS IT'S CONSIDERED AN ANNOYANCE. OCCURS EACH TIME THE VEHICLE IS IN USE.

AFTER SITTING FOR MORE THAN 1 HOUR, THE BRAKES SQUEAL UNTIL I HAVE APPLIED THE BRAKES FOR 5-8 TIMES.

BRAKE MASTER CYLINDER FAILURE - BRAKE FLUID ERROR MESSAGE APPEARED ON SCREEN AND OVER THE COURSE OF 24 HOURS THE BRAKES STOPPED WORKING. WHILE PUSHING THE PEDDLE COMPLETELY FLUSH TO THE FLOOR, THE VEHICLE HARDLY STOPPED. HAD THE CAR TOWED TO THE DEALERSHIP FOR REPAIR.

BRAKES FAILED. COMING TO A STOP SIGN ON CR 13, BRAKE PEDAL WENT TO THE FLOOR. BRAKES DID NOT SLOW OR STOP THE CAR AT ALL. PUMPED THE BRAKES 3 OR 4 TIMES, NO BRAKING. WENT THRU STOP SIGN HITTING ANOTHER VEHICLE. AIR BAGS DID NOT DEPLOY. AUTOMATIC BRAKING SYSTEM DID NOT ACTIVATE. ESTIMATES I WAS 50 YARDS FROM THE STOP SIGN WHEN I FIRST APPLIED THE BRAKES, SPEED BETWEEN 20-30 MPH.

LOSS OF BRAKES. BRAKE PEDAL WENT TO FLOOR AND CAR WOULD NOT STOP. BRAKE FLUID LIGHT WENT ON. TOWED TO DEALER, FOUND MASTER CYLINDER LEAKING INTO POWER BRAKE BOOSTER. BOTH PARTS REPLACED AND PROBLEM SOLVED THUS FAR. DEALER STATED MUST BE COMMON PROBLEM BECAUSE PARTS WERE BACKORDERED. MILAGE ON CAR IS 8,585 AT TIME OF BRAKE FAILURE. VEHICLE WAS MOVING AT TIME OF BRAKE FAILURE, MY WIFE WAS GETTING READY TO GET ON EXPRESSWAY. NO SIGN OF BRAKE FLUID LOSS WAS VISIBLE.

AFTER BACKING OUT OF MY GARAGE, MY XT5 AFTER 3 PREVIOUS BRAKE STOPS TWO WITH STOP SIGNS, THE NEXT STOP THE BRAKES LOCKED UP WITH A SUDDEN STOP. I DID NOTHING DIFFERENT WITH THE 4TH STOP WHEN THE BRAKES LOCKED. I NOTICED THAT THE BRAKE LIGHT WAS DISPLAYED AND NEEDED TO BE PRESSED TO IN ORDER TO DRIVE THE CAR TO REACH A CITY ROAD.

THIS CAR WAS SOLD TO ME WITH A DRIVER AWARENESS PACKAGE THAT INCLUDES LOW SPEED FRONT BRAKING AND I AM UNABLE TO GET IT TO WORK, A SALESPERSON DROVE THE CAR AND COULD NOT GET IT TO WORK AND A CADILLAC MECHANIC AT LINUS CADILLAC IN VERO BEACH, FL. DROVE THE CAR AND COULD NOT MAKE IT WORK.. THE CAR HAS BEEN TO TWO DEALERSHIPS FOR THIS ISSUE AND THE LAST DEALER MECHANIC AT LINUS ADVISED ME THAT THE SYSTEM IS NOT WORKING. CADILLAC DENIES THIS AND CLAIMS THE SYSTEM CANNOT BE TESTED BUT THAT IT IS IN THE CAR AND WILL WORK. I HAVE NEVER HEARD OF ANY SUCH THING. I HAVE TO MUCH DOCUMENTATION ON THIS ISSUE TO ATTACH BELOW. VIDEOS, E MAILS TO AND FROM THE DEALER SERVICE DEPT, ETC.
