- My 2018 Mazda CX 9 started stalling and jittering at idle and then eventually during slow driving. - Next day I got a check engine light, took to Mazda service center at the dealership I have been going to for last 6 years since I bought the car. - Service center diagnosed that there was a coolant leak through the cylinder head which seems to have cracked. - Further investigation indicated that this has been identified on many other similar Mazda engines and a Technical Service Bulletin had been issued by Mazda to Dealers. - On probing initially, dealership declined they were aware of any such problem. - The amount of repair for the engine replacement (cylinder head and other parts) is exuberant and is almost half of the value of my car, and is not expected for a low 44,000 miles car. - This had posed safety issue for my family since the stressed engine with leak in cylinder head could lead to fire and fatality. - I am awaiting response from Dealership and Mazda corporation case#[XXX] for a response especially when this issue has been filed under a class action lawsuit: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When this vehicle is low on fuel (but not empty) and under heavy acceleration, the fuel pump temporarily fails causing the engine to stall. This creates a serious safety hazard. Other 2019 Mazda models were covered for a similar defect under NHTSA Campaign Number 21V-875, however this specific VIN is questionably not included under that recall.

I WAS WAITING IN A STATIONARY POSITION, AT A RED LIGHT, BEHIND SOME OTHER VEHICLES, WITH MY FOOT ON THE BRAKE PEDAL. ALL OF A SUDDEN, THE VEHICLE STARTED TO LURCH FORWARD AS IF SOMEONE HAD STEPPED HARD ON THE GAS PEDAL! I WAS STRUGGLING TO KEEP THE CAR STILL BY DEPRESSING THE BRAKE PEDAL HARDER, BUT IT WOULDN'T STOP THE CAR. I HAD TO PUT IT IN PARK AND TURN OFF THE ENGINE TO STOP THE FORWARD THRUST OF THE VEHICLE.

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.
