2017 Mazda CX-5

TWO WEEKS AFTER I GOT THE VEHICLE, I WAS DRIVING ON A HIGHWAY DOING SPEEDS OF 45 TO 74. THE DRIVERS LAND CHANGE ASSIST WAS NOT WORKING AS A CAR WAS RIGHT BESIDE ME SEVERAL TIMES I NOTICED AND THE LIGHT WAS OFF. MY SON MENTIONED IT. DEC 22, 2017 2) I WAS DRIVING AT DUSK ON CRUISE CONTROL 74 MPH AND THE CAR SUDDENLY BRAKED AND A WARNING BRAKE! WAS ON THE DASH. I WAS IN THE FAST LANE WITH NO OBJECTS OR CAR IN FRONT.

WHILE DRIVING MY 2017 MAZDA CX-5, THE SMART CITY BRAKE SUPPORT (SCBS) INDICATOR ILLUMINATES ON THE DASH. THIS HAS HAPPENED MULTIPLE TIMES OVER THE PAST SEVERAL MONTHS, ON CLEAR, SUNNY DAYS AND IN RAIN AND/OR SNOW; ON CITY STREETS AND HIGHWAYS. THE RATE OF DRIVING SPEED VARIES FROM APPROX 10 TO 65 MPH. THE INDICATOR STAYS ON FOR ANYWHERE FROM 20 SECONDS OR UNTIL THE VEHICLE IS STOPPED (UPWARDS OF 20 MINUTES). SERVICE TECHS AT LOCAL DEALER WERE ABLE TO PULL THE FAULT CODE FROM THE COMPUTER, BUT IT WAS GENERIC AND GAVE NO GUIDANCE. MAZDA INITIALLY ACKNOWLEDGED THIS WAS A PROBLEM AND REPLACED THE CAMERA THAT CONTROLS THE SYSTEM (MOUNTED INTERIOR OF CAR AT WINDSHIELD), BUT WHEN PROBLEM PERSISTED WITH THE NEW CAMERA, MAZDA SAID IT'S "NORMAL" FOR THE LAMP ILLUMINATION TO DISPLAY ON THE DASH UNDER VARIOUS DRIVING CONDITIONS AND REFERENCED SERVICE ALERT SA-052/17, WHICH DISCUSSES FOG, RAIN, EXHAUST GAS FROM VEHICLE IN FRONT, ETC. TRIGGERING THE SCBS. ACCORDING TO THIS SERVICE ALERT, A DIRTY WINDSHIELD WILL ALSO TRIGGER THE WARNING LIGHT TO ILLUMINATE. THIS IS A SAFETY CONCERN BECAUSE NOT ONLY IS THE SCBS NOT FUNCTIONING PROPERLY, WHEN THE LIGHT ILLUMINATES IT DISTRACTS FROM THE ACT OF DRIVING.

TL* THE CONTACT OWNS A 2017 MAZDA CX-5. THE CONTACT STATED THAT THE SMART CITY BRAKE SYSTEM FAILED TO FUNCTION PROPERLY WHEN ACTIVATED AND MODIFIED TO A SPECIFIC DISTANCE OR SPEED. THE DEALER (MAZDA OF MESQUITE, 15900 LYNDON B JOHNSON FWY, MESQUITE, TX 75150, (972) 686-6200) WAS NOTIFIED, BUT WAS UNABLE TO REPLICATE AND DIAGNOSE THE FAILURE. THE MANUFACTURER PROVIDED A TSB THAT INDICATED THAT, WITHOUT A WARNING INDICATOR OR WARNING CHIME, THE FUNCTION WAS NOT ABLE TO BE REPLICATED AND THE SYSTEM WAS PERFORMING NORMALLY. THE MANUFACTURER DID NOT SEND A TECHNICIAN TO TEST DRIVE THE VEHICLE AND DETERMINE IF THE FUNCTION WAS PROPERLY WORKING. THE FAILURE MILEAGE WAS 0.

ACCORDING TO CONSUMER REPORTS (AUG. 2017, PAGE 58, LAST PARAGRAPH) THE MAZDA'S NEW CX-5'S FORWARD COLLISION WARNING WITH LOW-SPEED AUTOMATIC EMERGENCY BRAKING STANDARD SHOULD BE APPLAUDED. THESE FEATURES MALFUNCTIONS IN LAS VEGAS DURING HOT WEATHER. MAZDA KNOWS ABOUT THE PROBLEM AND HAS NO FIX. WE BOUGHT A MAZDA CX-5 ON JUNE 9, 2017. WHILE DRIVING ON THE FREEWAY ON JULY 21, 2017 THE CAR QUIT WORKING PROPERLY AND WE HAD THREE WARNING MESSAGES COME UP ON THE DASHBOARD: 1.SMART CITY BRAKE SUPPORT MALFUNCTION 2.SMART BRAKE SYSTEM MALFUNCTION 3. FORWARD CAMERA MALFUNCTION. HAD I NOT BEEN PAYING CLOSE ATTENTION WHILE USING THE CRUISE CONTROL THE CAR MIGHT HAVE REAR-ENDED THE CAR IN FRONT AT 60 MPH. THE DEALER SERVICE STAFF I TALKED TO ON THE PHONE WHEN I GOT HOME SAID THAT MAZDA KNEW ABOUT THE FAILURES. MAZDA SAID THESE ERRORS ARE CAUSED BY EXCESSIVE HEAT AND MAZDA HAS HAD MANY COMPLAINTS IN MANY LOCATIONS. THERE IS PRESENTLY NO FIX. IT SEEMS TO WORK OK WHEN THE WEATHER IS COOLER. THESE ARE SAFETY FEATURES WE PURCHASED AND THEY FAILED WHILE WE WERE DRIVING IN LAS VEGAS. THE TEMPERATURE WAS 104 AT THE TIME. NOT EXCESSIVE FOR LAS VEGAS NOR OTHER PARTS OF THE SOUTHWEST DESERT. I CURRENTLY HAVE PICTURES OF TWO OF THE WARNING MESSAGES THAT FLASHED ON THE DASHBOARD AND CAN BE SEEN AT HTTPS://PHOTOS.APP.GOO.GL/0MFDPF5WZVOUX2SP2. THIS SEEMS LIKE A MAJOR FLAW OF THE MAZDA CX-5 IF THEIR PREMIER PACKAGE SAFETY FEATURES FAILS TO WORK WHEN THE OUTSIDE TEMPERATURE IS AROUND 104. THE CAR SHOULD NOT BE RECOMMENDED, OR EVEN SOLD, WITH THESE FEATURES UNTIL MAZDA GETS THIS FIXED. MAYBE OTHER MAZDA MODELS HAVE THIS FLAW.
