2015 Mazda CX-9 Problems

My Mazda has been serviced regularly, in fact my next oil change isn't for 2,000 more miles. I was driving when I heard this weird noise. I looked at the dash and the oil light was flashing and the temperature was over heating. I could also feel the vehicle getting sluggish. I pulled over on the interstate. All the lights were on by this time. I popped the hood and there wasn't any coolant in the resivour anymore. I let the car cool down and I added some water as I was 1 mile from the exit where there was a gas station. I had to baby the car to the exit and shut it off whenever it got hot. The oil was full and seemed overfull even..... Mechanic is guessing the coolant leaked if the engine.... I was stranded for hours with 4 children...

We have a 2015 Mazda CX-9 Touring with All-Wheel Drive (AWD). The issue that has been happening is a flashing check engine light (CEL) indicator showing up in the gauge cluster. This issue originally started in October of 2023. I was on the highway doing at least 55 miles per hour (mph). Before the light actually came on, I had already felt the vehicle shaking, and also noticed the acceleration was sluggish. In the blink of an eye, the CEL came on and started flashing. After that point, the CEL stayed on. I was able to get to my destination safely. We took the vehicle to a shop, and told the mechanics the issue, but they could not re-create what happened. We stopped driving the vehicle as much after this first encounter. A couple of months later, the issue still persisted, and we took it to another shop. They changed the spark plugs, and the vehicle had been driving CEL-free for several months. Recently, we were going to take the vehicle out for a drive, and noticed the vehicle shaking (before the CEL officially came on) again. The CEL flashed and came on. As of this moment, the CEL pops up and stays on when starting the vehicle. I put in a code reader, and the code that came up was “PO304 Cylinder 4 Misfire Detected.” We are figuring out what our next plan(s) is/are with the vehicle. I looked at some forums for the 2007-2015 Mazda CX-9 Generation, and I noticed that someone mentioned that there was an issue with the injector pigtail wire (one of the fuel injectors). They also mentioned spark plugs and coil plugs. But they still had an issue and it seemed to be not resolved. I'm wondering if this issue could have a direct or indirect connection with the Takata Airbag recall that was issued on August 13th, 2024 with a "Do Not Drive" alert.

MY BRAKE PEDDLE BEGAN HISSING AND MY VEHICLE DOES NOT WANT TO STOP WHEN IN MOTION, I TOOK MY VEHICLE TO A MAZDA DEALERSHIP AND THEY STATED IT WAS THE BRAKE BOOSTER WHICH IS A PROBLEM MAZDA HAS BEEN HAVING, BUT MY VEHICLE IS NOT IN THE YEARS SPECIFIED IN THE WARRANTY EXTENTION. THE DEALERSHIP STATED MAZDA IS NOT WILLING TO HELP OR FIX THE ISSUE, AND THAT WE WOULD HAVE TO PAY OUT OF POCKET. IT IS THE EXACT SAME PROBLEM THE EARLIER MODELS HAVE BEEN EXPERIENCING AND ARE BEING FIXED AND MINE IS NOT. MAXDA IS AWARE OF THIS DEFECT AND WILL NOT HELP ME. MY VEHICLE ONLY HAS 58K MILES AND SHOULD HAVE THESES ISSUES. THE HARD BRAKE PEDDLE AND HARD BRAKING OCCURS ON ROADWAYS, IN DRIVEWAYS ANYTIME THE VEHICLE IS MOVING. IT IS UNSAFE AND I HAVE AVOIDED SEVERAL COLLISIONS.

THE FRONT BRAKES MAKE A GRINDING NOISE WHEN REPEATEDLY APPLYING THE BRAKES WHEN GOING DOWNHILL OR SLOWING REPEATEDLY FROM SPEEDS OF 65 OR SO. I BELIEVE THE BRAKE PARTS BECOME HOT AND CREATE SOMETHING GOOGLE SEARCHES CALL "JUDDER". I HAVE HAD THE STEERING WILL START SHAKING AS WELL. AFTER REPEATED REQUESTS TO MAZDA CORPORATE AND VISITS TO TWO DEALERS, MAZDA CLAIMS THE BRAKES WORK AS DESIGNED. ONE SERVICE MANAGER AT BROWNING MAZDA STATED THE FRONT ROTORS ARE TOO SMALL TO STOP A CAR OF THIS WEIGHT, BUT THIS STATEMENT IS NOT WRITTEN. REGARDING THE VEHICLE STABILITY CONTROL, WHEN I TURN LEFT AND GO DOWNHILL FROM MY DRIVEWAY AT A SLOW SPEED OF APPROX 10MPH, I USUALLY HAVE NO THROTTLE CONTROL. I NEED TO APPLY THE BRAKES TO REGAIN ANY CONTROL OF THE THROTTLE. ONCE AGAIN TWO DEALERS TELL ME THIS IS WITHIN DESIGN SPECS. MAYBE THIS IS TRUE, HOWEVER, I HAVE NO WAY TO IMMEDIATELY GET OUT OF THE WAY OF OTHER CARS AS I HAVE TO BRAKE FIRST FOR THE THROTTLE TO RETURN. DOESN'T SEEM RIGHT TO ME. ALSO, MY COMBINED MPG IS ABOUT 13.7 WHEN MAZDA STATES IT SHOULD BE ABOUT 18. HOW CAN THEY MAKE SUCH A CLAIM LIKE THIS AND GET AWAY WITH IT. IT IS NOT JUST MY CX-9, MANY PEOPLE COMPLAIN ON THE INTERNET. AGAIN, MAZDA STATES THE CAR IS WITHIN SPECS.

I was driving into the highway and my vehicle just shut off. I was in the car with my children and I was scared that we were going to be rear ended. I had my mechanic look at the car and he advised me that the water pump leaked and the coolant leaked into the oil. I’m having another mechanic provide me with an estimate of how much the repair is going to cost. After the car shut off and I tried to turn it in again the batter, engine and oils light went off and I had the car towed to the local mechanic.

TL* THE CONTACT OWNS A 2015 MAZDA CX-9. THE CONTACT STATED THAT THE AIR BAG WARNING LIGHT WOULD ILLUMINATE INDICATING THAT THE AIR BAG WAS NOT ACTIVATED DESPITE AN OPERATING IN THE SEAT. THE CONTACT INFORMED THE DEALER WHERE IT WAS VERIFIED THAT THE AIR BAGS WEIGHT REQUIREMENTS WERE IN FACT BEING MET HOWEVER, THE AIR BAG SENSOR FAILED TO DETECT THE OCCUPANT IN THE SEAT. THE FAILURE COULD NOT BE DETECTED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE MILEAGE WAS 6,500.

WHILE STOPPED IN TRAFFIC I WAS HIT FROM BEHIND BY A CAR AT MINIMUM GOING 40MPH WHILE PROPELLED MY CAR INTO THE VEHICLE IN FRONT OF ME. THE ENTIRE FRONT AND BACK ENDS OF MY CAR ARE SMASHED IN/HANGING ON AND MY AIR BAGS DID NOT DEPLOY. AUTOBODY SHOP INDICATED THE AIR BAGS SHOULD HAVE GONE OFF WITH THAT MUCH DAMAGE. *TR

The wiring harness on the headlight for my Mazda CX-9 has and continues to melt, causing the bulb to be useless. The only issue that will seem to correct this issue is installing new headlights. According to my research this is a problem that is common to Mazda CX-9 vehicles.

I'VE ONLY HAD MY MAZDA FOR 10 MONTHS AND HAVE HAD THE SAME PROBLEM TWICE. THE RIGHT HEADLIGHT SOCKET HAS MELTED AND RENDERING THE BULB USELESS. I NOTICED THE SOCKET HAD BEEN SPLICED INTO THE OLD HARNESS SO I TOOK IT TO THE LOCAL MAZDA DEALER SERVICE. THEY GAVE ME AN ESTIMATE TO INSTALL A COMPLETE NEW HARNESS. TO REMOVE THE LIGHT FIXTURE, THE BUMPER WILL NEED TO BE REMOVED. THE ESTIMATE FOR THIS WAS $643.25! I PURCHASED THE WIRING HARNESS AND WITH HELP INSTALLED IT THROUGH THE PORTS IN THE REAR OF THE FIXTURE IN JANUARY 2019. RECENTLY, THE LIGHT STOPPED ILLUMINATING AGAIN ONLY TO FIND THIS SAME SOCKET HAS MELTED AS THE PREVIOUS ONE DID. IF THIS PATTERN PERSISTS, IT COULD COST $1300 PER YEAR TO HAVE MAZDA FIX IT. THE SPLICED HARNESS TELLS ME THAT THIS HAS BEEN A PROBLEM WITH THIS VEHICLE AT LEAST ONCE BEFORE! BEFORE BUYING THIS MAZDA I FOUND A REVIEW ON KELLY BLUE BOOK'S WEBSITE WITH ONE FRUSTRATED OWNER THAT HAD A SIMILAR REOCCURRING PROBLEM EVERY 3 MONTHS. AT THE TIME I THOUGHT IT MAY BE AN ANOMALY. I BELIEVE UPON INVESTIGATION YOU WILL FIND IT'S MORE OF A PERPETUAL SAFETY HAZARD, INCONVENIENCE AND EXPENSE. I WILL SEND DOCUMENTS AND PHOTOS WITH THIS REQUEST FOR A RECALL INVESTIGATION.

DRIVER SIDE EXTERIOR MIRROR VIBRATES AT HIGHER SPEEDS AND HAS NOTICEABLE SHAKING. SAFETY DISTRACTION WHILE DRIVING.

TL* THE CONTACT OWNS A 2015 MAZDA CX-9. WHILE DRIVING APPROXIMATELY 55 MPH, THE DRIVER SIDE MIRROR VIBRATED CAUSING THE CONTACT'S VISION TO BECOME DISTORTED THROUGH THE MIRROR. AS A RESULT, THE CONTACT WAS UNABLE TO IDENTIFY THE OBJECTS. THE VEHICLE WAS TAKEN TO THE DEALER, BUT THE TECHNICIAN WAS UNABLE TO RESOLVE THE ISSUE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 5,000.

TL* THE CONTACT OWNS A 2015 MAZDA CX-9. WHILE DRIVING VARIOUS SPEEDS, THE DRIVER'S SEAT MOVED BACK AND FORTH WITHOUT WARNING. THE DEALER (HALL MAZDA VIRGINIA BEACH, 4372 HOLLAND ROAD, VIRGINIA BEACH, VA 23452, (877) 438-1954) REPAIRED THE SEAT AND SEAT FRAME TWICE, BUT THE FAILURE RECURRED. THE VEHICLE WAS NOT REPAIRED A THIRD TIME. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 69,000.

WE BOUGHT THIS VEHICLE IN JUNE OF 2015 AND ABOUT 2 OR 3 MOTHS AFTER I NOTICED THAT THE REAR DRIVER SIDE ROTOR HAD A DEEP SCRATCH ON IT. THEY FIXED IT BY SANDING THE ROTOR INSTED OF REPLACING THE ROTOR. NEXT TIME I BROUGHT WAS AN OIL LEAK ON THE FRONT SIDE OF THE MOTOR ABOUT 4000MILES. THEY SAID THAT THE OIL FILTER IS LOOSED. SO ME AND MY WIFE WENT HOME HAVING SOME PIECEOF MIND THAT I BROUGHT THE CAR TO A DEALERSHIP AND THEY WILL DO THE RIGHT THING. BUT AT 7000 MILES I BROUGHT OUR VEHICLE FOR FIRST OIL CHANGE AND TOLD THEM THERES A SCREECHING SOUND ON ONE OF THE PULLEYS IN THE MOTOR. ALSO THE STEERING WHEEL IS SHAKING DRIVING AT 55 MPH OR HIGHER ESPECIALLY WHEN YOU'RE LIGHTLY BREAKING AT THAT SPEED. WE LEFT THE CAR FOR A DAY AT THEIR SERVICE THINKING THAT THEY WI ADDRESS TO THOSE PROBLEM. BUT WHEN WE PICK UP THE CAR NONE OF MY CONCERNS. HAD BEEN RESOLVE. SO WE BROUGHT THE CAR HOME BECAUSE IT WAS LATE AT NIGHT AND THEIR SERVICE TECHNICIANS ARE ALL GONE FOR THE DAY. BUT UPON ARRIVING AT THE HOUSE TO CHECK THE OIL LEVEL I NOTICE A BIG SCRATCH ON THE HOOD I WAS AGGRAVATED AT THAT MOMENT BECAUSE THEY DIDN'T DO A THING TO MY CONCERNS AND NOW THIS IS WHAT YOU WILL SEE. BY THE WAY WE HAVE A BLACK CX-9 AND YOU CAN EASILY SPOT A SCRACT IF THERE IS ONE. BUT THAT'S NOT THE MOST FRUSTRATING PART OF IT. BECAUSE WHEN I WENT UNDERNEATH THE CAR TO CHECK THE OIL FILTER. I NOTICED THAT THE FILTER WAS LOCATED IN THE MIDDLE OF THE MOTOR AND THERES NO WAY THAT IF LEAKS HAPPEN ON THAT SPOT THAT IT WILL GO ALL THE WAY TO THE FRONT SIDE OF THE MOTOR NEAR THE PULLEYS WHERE MY PREVIOUS OIL LEAKED COMPLAINT WAS. I THINK THEY WERE TRYING TO HIDE TO AVOID WARRANTY REPAIR ON IT. SO I CALLED THE DEALERSHIP SERVICE AND MY WIFE BROUGHT IT OVER THERE. WHEN THEY GOT CORNERED ABOUT THE PROBLEM I GUESS THEY DON'T HAVE A CHOICE BUT TO WORK ON IT. IT WAS A BAD POWER STEERING PUMP AND THEY WILL REPLACE IT

I PURCHASED THE CAR NEW ON SEPTEMBER 18,2015. HAVING THE CAR FOR 3 MONTHS I HAVE BEEN AT THE SERVICE DEPARTMENT 3 TIMES. I GOT HOME THE FIRST DAY AND THE BELT WAS NOT REGISTERING AND WAS MAKING NOISE WHEN I HAD IT ON. THE LAST 2 TIMES I CONTINUE TO HEAR NOISE COMING FROM THE CAR. THE NOISE IS HEARD FROM UNDERNEATH AND IT HAS TO BE DRIVEN FOR SIGNIFICANT AMOUNT OF MINUTES BEFORE THE NOISE GOES AWAY. I RECORDED THE NOISE ON NOVEMBER 28,2015 AND CALLED THE DEALER VERY UPSET BECAUSE ITS A PROBLEM THAT'S NOT BEING ADDRESSED AND FIXED. I DROPPED THE CAR OFF ON MONDAY NOVEMBER 30,2015 AND WAS TOLD YESTERDAY DECEMBER 1,2015 THAT THEY DONT SEE THE PROBLEM.THIS IS A NEW CAR AND I NEVER TEST DRIVEN BEFORE BUYING. I NEED HELP. I HAVE THE RECORDING BUT I CANT ATTACH IT ON HERE.
