NHTSA lists 2 safety recalls and 100 owner complaints for the 2003 Cadillac Escalade Ext. Most complaints involve electrical system (27) and service brakes, hydraulic (15). The EPA rates it 13 mpg combined.
ON CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE GALVANIZED STEEL TAILGATE SUPPORT CABLES THAT RETAIN THE TAILGATE IN THE FULL OPEN (HORIZONTAL) POSITION MAY CORRODE, WEAKEN, AND EVENTUALLY FRACTURE. IF BOTH CABLES FRACTURED, THE TAILGATE WOULD SUDDENLY DROP AND STRIKE THE TOP SURFACE OF THE REAR BUMPER.
CERTAIN SPORT UTILITY VEHICLES, PICKUP TRUCKS, AND PASSENGER VANS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 135, ?PASSENGER CAR BRAKE SYSTEMS.? SOME OF THESE VEHICLES WERE PRODUCED WITH AN OUT-OF-SPECIFICATION BRAKE HYDRO-BOOST HOUSING RELIEF VALVE BORE.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“WHILE DRIVING I LOST ALL USE OF BRAKES IMMEDIATELY AFTER THE BRAKE SYSTEM LIGHT CAME ON DRIVING 45MPH ON A CITY STREET. WHILE DRIVING THE STABILITY CONTROL LIGHT CAME ON AND CAR SHUT OFF 60MPH ON THE HIGHWAY. ON ANOTHER OCCASION STABILITY CONTROL LIGHT CAME ON AND STEERING COLUMN LOCKED UP WHILE TURNING. T/C LIGHT AND ENGINE LIGHT CAME ON WHILE DRIVING 35 MPH ON A CITY STREET AND IMMEDIATELY LOST RESPONSE FROM THE GAS PEDAL. DASH LIGHTING SYSTEM FLASHES DIFFERENT INDICATOR LIGHTS, DISPLAY RANDOMLY GOES OUT WHILE DRIVING.”
“TL* THE CONTACT OWNS A 2003 CADILLAC ESCALADE. THE CONTACT STATED THAT, ON DIFFERENT OCCASIONS, THE ACCELERATOR AND BRAKE PEDALS SEIZED AND FAILED TO RELEASE WHEN NEEDED. THE FAILURE PRESENTED THE RISK OF A POTENTIAL CRASH. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBERS: 04V045000 (SERVICE BRAKES, HYDRAULIC) AND 02V224000 (ELECTRICAL SYSTEM); ALTHOUGH, THE FAILURES WERE SIMILAR TO THE RECALL CAMPAIGNS. THE VEHICLE WAS ALSO NOT INCLUDED IN NHTSA ACTION NUMBER: EA11001 (SERVICE BRAKES, HYDRAULIC). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS NOT AVAILABLE.”
“I WAS ON I 75 PASSING UNDER MILLER RD IN FLINT, MI WHEN TRAFFIC STARTED TO BACK UP AND SLOW DOWN. I APPLIED THE BRAKES AND THE CAR STATED TO SLOW DOWN, THE BRAKE PEDDLE THEN WENT TO THE FLOOR AND I HAD NO BRAKES. I WAS ABLE TO DOWN SHIFT TO 1ST GEAR AND GET TO THE SIDE OF THE ROAD. THE CAR SLOWED DOWN TO WHERE I COULD GET IT INTO REVERSE TO STOP IT. WE WHERE SO LUCKY! I GOT IT TO A CADILLAC DEALER IN DEARBORN, MI AND FOUND OUT THAT THE MAIN BRAKE LINE HAD RUSTED THROUGH. I HAD ALL THE BRAKE LINE REPLACE. I HAVE MAJOR CONCERNS THAT THERE ARE THOUSANDS OF GM VEHICLES WITH THIS PROBLEM STILL ON THE ROAD. I HAVE SINCE BEEN TOLD THAT GM HAD A BRAKE LINE MATERIAL PROBLEM DURING THE EARLY 2000 THAT LEAD TO RUSTING OUT OF THE LINES. PLEASE LOOK INTO THIS FOR THE SAFETY OF OTHERS. THE DEALER WAS LES STANFORD CADILLAC UPDATED 10/9/15 *LN”
