> I have a 2018 Mazda CX-9 with about 70,000 miles on it. Since 2020 this vehicle started developing cracks in the infotainment center screen. I only had about 23,000 miles on it at that time. the cracks are now starting to obscure my back up camera, communication system and nav system displays causing a safety issue. It is distracting to not be able to see clearly on this screen and I am afraid something will happen to me or my kids. About a year ago I did take this car to the local mazda dealer, for the longest time I thought I did something to it, but I did not. They called mazda customer service and no good will was offered. there is a technical service bulletin out but not a recall. There are several models older than my vehicle that have had this screen repaired free of charge by mazda. Same issue - nothing different then what is going on with my car. There are many many of the very same complaints online. can some please investigate this issue. it is ridiculous.

"Spider Cracks" in both the left and right top corners that continue to spread, creating larger blind spots while in reverse. This is an issue that Mazda is aware of and impacts many models from 2014 until 2019. Even though this may not be considered a "safety feature" in it's traditional form, it has become common practice to rely on this feature while reversing the vehicle. Much like additional airbags may not be required, if they are, they should be fixed when they are proven to be faulty. Both the local dealer(Roger Beasley Austin North) and MazdaUSA refused to cover the cost of fixing the issue even though they are aware it is faulty. There is even a Service Notice that was put out by NHTSA that discusses this issue and my model is included, however I have been repeatedly told my VIN # does not qualify.

the Mazda Connect information screen has small spider cracks on the upper right part of screen that are inside the glass (if you run your finger over the crack it feels smooth). Information websites pertaining to Mazda vehicles say it's caused by temperature change.

The Mazda connect touch screen has started cracking in the corners 3 so far the past 4 months. I cannot feel the cracks. They are spreading and I am concerned eventually I will not be able to use my navigation. System at all as I will not be able to read it. I am concerned the touch ability will be lost. I understand many other Mazdas have this same defect but my model is not covered under the extended warranty like the other Mazda owners were given - the extended warranty covers vehicles older than mine. It is the same defect.

HAPPENED TO ME TWO TIMES IN PAST THREE WEEKS, WHERE I AM COMING TO A STOP, OR HARDLY MOVING, AND CAR SUDDENLY ACCELERATES. HAD MY FOOT ON THE BRAKE AND THE CAR WAS STILL TRYING TO ACCELERATE. YESTERDAY, 4/24/21 IT TOOK ALL MY STRENGTH ON THE BRAKE TO KEEP THE CAR FROM PULLING INTO ONCOMING TRAFFIC. I HAVE BEEN DRIVING FOR 39 YEARS AND HAVE OWNED MANY CARS, AND SOMETHING LIKE THIS NEVER HAPPENED TO ME. I WILL BE BRING THE CAR DEALERSHIP TOMORROW, THE CAR HAS ONLY 10K MILES ON IT AS WE DON'T DO A LOT OF DRIVING WITH IT AS WE OWE TWO CARS. I DID NOT HAVE MY FOOT ON THE WRONG PEDAL, THIS IS VERY DANGEROUS AND IF THE DEALER DOES NOT FIND ANYTHING WITH THE CAR, I INTEND TO SELL IT, AS THIS IS PROBABLY ONE OF THE SCARIEST EXPERIENCE I HAD WITH A CAR. IT IS INTERMITTENT, SO I AM NOT SURE WHEN ITS GOING TO OCCUR, BUT TWICE IN THE LAST FEW WEEKS IS NOT COINCIDENCE ( IT ALSO HAPPENED TO MY WIFE A FEW MONTHS AGO, BUT WE THOUGHT IT COULD HAVE BEEN DUE TO SNOWY ROAD CONDITIONS). IN ONE CASE I WAS COMING UP TO A STOP SIGN, AND WAS BRAKING AND CAR WAS ACCELERATING AS I TRIED TO BREAK. I HAD TO PUT CAR IN NEUTRAL AND THE SHUT OFF CAR TO GET TO STOP. YESTERDAY, I WAS PULLING OUT OF A PARKING LOT, AND WAS WAITING FOR AN ON COMING CAR TO PASS ME BEFORE I COULD TURN ONTO ROAD, WHEN CAR WAS TRYING TO ACCELERATE, WHEN I HAD MY FOOT ON BRAKE, AND TOOK EVERYTHING TO KEEP THE CAR FROM ACCELERATING FORWARD INTO ON COMING CAR. ONCE CAR PASSED, I MADE TURN ONTO ROAD, AND ISSUE DID NOT REPEAT ON THE REMAINING MILE TO MY HOUSE. I WENT ONTO A MAZDA FORUM AND I SAW A FEW OTHERS WHO RAISED THE SAME CONCERN/ISSUE.

ON FRIDAY (JUNE 29TH, 2018) AROUND 9:29 PM, MY CAR BROKE DOWN WHILE MY FAMILY AND I WERE TRAVELING FROM ROCHESTER NY TO BOSTON MASSACHUSETTS. I WAS DRIVING DOWN THE MASSACHUSETTS TURNPIKE WHEN ALL OF A SUDDEN MY CHECK ENGINE LIGHT TURNED ON AND MY CAR JUST STARTED TO SLOW DOWN IN THE MIDDLE OF THE HIGHWAY. I WAS ABLE TO PULL OVER IN TIME AND CALLED MAZDA ROADSIDE ASSISTANCE BECAUSE AFTER THE CAR STOPPED, IT WOULDN'T TURN BACK ON. SINCE WE WERE ON A RESTRICTED HIGHWAY, MY CAR HAD TO BE TOWED AND WE WERE TAKEN TO A SAFER LOCATION. WHEN THE CAR WAS PUT DOWN, IT TURNED ON AND THE CHECK ENGINE LIGHT WAS STILL ON AND THE FUEL GAUGE SAID THAT THE CAR STILL HAD 40 MILES LEFT. THE GUY THAT TOWED OUR CAR SAID THAT IT MIGHT HAVE BEEN A FUEL ISSUE, SO WE WENT TO GET GAS. ONCE WE FILLED UP OUR TANK THE CHECK ENGINE LIGHT WAS STILL ON BUT WE WERE ABLE TO REACH OUR DESTINATION. THE NEXT MORNING, I TOOK THE CAR TO THE NEAREST MAZDA DEALERSHIP AND THEY RESTARTED THE CAR AND ACCORDING TO THEIR REPORT NOTHING WAS WRONG WITH THE CAR. THEY SAID THAT IT WAS SAFE TO DRIVE BUT THEY HAD NO CLEAR REASON AS TO WHY THE FUEL GAUGE WASN'T STATING THE CORRECT INFORMATION. AFTER THE TRIP I, REPORTED THIS ISSUE TO MAZDA AND THEY DIDN'T ANSWER ME UNTIL TWO WEEKS LATER. THEIR RESPONSE WAS THAT THERE WAS PROBABLY NOTHING WRONG WITH THE VEHICLE AND THAT THIS WAS A ONE TIME ISSUE. I DID RESEARCH ON MY OWN AND DISCOVERIES THAT SOMEONE FROM SAUDI ARABIA HAD A SIMILAR ISSUE. SINCE MAZDA HASN'T BEEN WILLING TO HELP RESOLVE THE SITUATION I AM FILING THIS COMPLAINT BECAUSE I AM NOT WILLING TO PUT MY FAMILIES LIFE IN THE SAME RISK AGAIN.

I PURCHASED A NEW MAZDA CX-9 IN SEPT 2017 BECAUSE IT HAD THE HIGHLY TOUTED SMART CITY BRAKING SYSTEM FOR WHICH I PAID THOUSANDS EXTRA. I HAD HAD A PREVIOUS REAR END COLLISION AND WANTED TO BE SURE THIS SYSTEM WOULD AT LEAST WARN ME. I SET UP SOME CARDBOARD BOXES WRAPPED IN ALUMINUM FOIL. I SLOWLY (10 MPH) DROVE THE CAR INTO THEM WITHOUT TOUCHING THE BRAKE OR ACCELERATOR. THE CAR DID NOT SLOW DOWN OR WARN ME.(I TRIED SENDING A VIDEO TO YOU FROM MY IPHONE WHICH MAY NOT GO THROUGH) I MADE AN APPOINT TO REPAIR THIS OBVIOUS FACTORY DEFECT AND SIGNIFICANT SAFETY ISSUE. THE SERVICE MANAGER AT OLYMPIA LINCOLN /MAZDA(AND PUYALLUP MILAM MAZDA) REFUSED TO REPAIR IT THEY STATED AND SHOWED ME A PRINT OUT FROM MAZDA FACTORY THAT FORBIDS REAL TIME TESTING AND STATED THAT IF THE TROUBLE LIGHT IS NOT ON THEY AREN'T ALLOWED TO REPAIR OR REAL TIME TEST IT. I THINK THAT THE FACTORY IS AFRAID OF DEALING WITH A MASSIVE SAFETY RECALL. TO COMPOUND THINGS THE ACTIVE LIVE TRAFFIC DISPLAY DOESN'T WORK EITHER WHICH MAKES MATTERS WORSE SINCE I CAN'T SEE WHERE AN ACCIDENT HAS OCCURS IN REAL TIME. I UNDERSTAND ITS DEFECTIVE IN MOST MAZDAS WITH NAVIGATION IN 2016 AND BEYOND. THE IS A CLASS ACTION LAW SUIT STARTING TO BE FILED ABOUT THIS. *BF CONSUMER STATED REGARDING DEFECTIVE AUTOMATIC BRAKING SYSTEM ON 2018 MAZDA CX-9. I HAVE NOT HEARD BACK AFTER FILING THIS COMPLAINT 2 MONTHS AGO. UPDATED 8/24/18*JB
