I'M CONSTANTLY HAVE A FRONT WINDSHIELD ERROR : CAUSING MY VEHICLE TO JUST AUTOMATICALLY STOPING WHILE DRIVING ON THE FREEWAY AND STREETS. MY AIR BAGS DIDN'T DEPLOY WHEN I WAS I A ACCIDENT . I'VE TAKEN IT TO THE DEALER 3 TIMES ALREADY AND THEY ALWAYS HAVE A DIFFERENT EXCUSE OR REASON
TAKATA RECALL - WAS IN A HEAD ON COLLISION WITH 3 OTHER CARS INVOLVED, ALL CARS WERE TOTALED AND ALL OF THE OTHER CARS' AIRBAGS DEPLOYED WITH THE EXCEPTION OF MINE AND I WAS INJURED AS A RESULT.
Passenger seat heater either had a grounding issue or shorted out, causing to seat to start smoldering and catching fire, destroying the seat. There has been recalls and lawsuits for this specific issue on this model in other years, but not for this model year.
I was resting my foot on my brake in the middle of sealed traffic and when I eased up to move forward when traffic my brakes did stop causing me to bump the car ahead of me. After that what came next was that my car then accelerated forward with my foot still on the brake. By then 2 other vehicles were involved in this accident. My car is now totaled from this.
EMERGENCY PARKING BRAKE ('EPB') BEGAN TO MALFUNCTION FOLLOWING RECALL TO FIX ELECTRICAL COMPONENTS ON MAZDA CX-9, 2018. EPB WILL NOT RELEASE, OR WILL UNEXPECTEDLY AND SUDDENLY RELEASE WITH CAR ACCELERATING IN GEAR ('DRIVE' OR 'REVERSE'). MOST RECENTLY WHEN ACTIVATING THE EMERGENCY PARKING BRAKE ((CAR WAS ON A A ROADWAY INCLINE) THE BRAKE WOULD NOT RELEASE, AFTER 2 HOURS OF BEING STRANDED AND OF ATTEMPTING TO GET THE BRAKE TO RELEASE, ( INCLUDING ROCKING/SHIFTING/ALTERNATING GEARS/BRAKING/SEAT BELT ON/SEAT BELT OFF/ MANUAL BRAKE ON/OFF AND FOLLOWING ALL MANUAL PROCEDURES REPETITIVELY) A CELL PHONE CALL TO THE MAZDA SERVICE MANAGER WHO SUGGESTED ROCKING THE CAR BACK AND FORTH BETWEEN GEARS ) THE EMERGENCY PARKING BRAKE SUDDENLY AND UNEXPECTEDLY 'RELEASED', SENDING THE CAR LURCHING FORWARD AND REQUIRING DRIVER TO SLAM ON BRAKES TO AVOID DRIVING OVER A CLIFF). VEHICLE EPB INSPECTION REQUESTED, MAZDA SERVICE MANAGER STATED THE EPB IS, 'NO LONGER NECESSARY FOR VEHICLE SAFETY', BLAMED THE MALFUNCTION ON 'BREAD CRUMBS' , OFFERED TO REPLACE A DEFECTIVE CONSOLE SWITCH (PRESUMABLY WITH ANOTHER NEW, BUT ALSO DEFECTIVE, SWITCH) BUT REFUSED TO INSPECT THE MECHANICAL/OPERATIONAL ASPECTS OF THE AUTOMATIC EMERGENCY PARKING BRAKE SYSTEM (FOR ABNORMAL RUST, WATER LEAKS, DEFECTIVE CABLES, DEFECTIVE ELECTRICAL WIRING, ETC.). MAZDA USES THE SAME MANUFACTURER OF EPB FOR ALL MAZDA CX SERIES VEHICLES. FEDERAL NHSA RECALLS FOR EPB MALFUNCTIONS WERE MANDATED FOR ALL MAZDA CX SERIES VEHICLES - EXCEPT THE MAZDA CX 9. THE CX 9 USES THE SAME EPB SYSTEM AS DO THE OTHER MAZDA CX SERIES MODELS. IT STANDS TO REASON THAT THE BRAKING ISSUES FOR OTHER MAZDA RECALLS IS THE SAME REASON WHY THE CX 9 SHOULD HAVE RECALLS TO FIX THE AUTOMATIC EMERGENCY PARKING BRAKE SYSTEM. PLEASE ISSUE A RECALL FOR MAZDA CX 9 VEHICLES TO FIX THE AUTOMATIC EMERGENCY PARKING BRAKE DEFECT(S). THANK YOU.
My 2018 Mazda Cx-9 equipped with the skyactiv-g 2.5T developed a serious cylinder-head/cooling-system failure. The vehicle began to lose coolant with no apparent external leak and subsequently displayed and engine -overheating warning. It continued to lose coolant after a flush. The Mazda dealership inspected the vehicle and diagnosed a warped cylinder head; I was also advised that the engine oil was milky, indicating coolant contamination. The affected component is the engine cylinder head/cooling system. This condition created a safety concern because loss of coolant and overheating can lead to severe engine damage or engine failure and potentially leave the vehicle disabled while driven. Mazda has formally documented a cylinder head coolant leak condition in certain 2016-2020 CX-9 2.5T, including cracks around the cylinder head, exhaust manifold area, and states that the cylinder hear/exhaust manifold gasket design was modified to address the condition. Mazda then established customer service program CSP11, extending coverage for the specific cylinder head coolant leak condition to 10 years/120,000 miles, whichever comes first. The dealer has confirmed and inspected my vehicles condition, and Mazda customer experience has also review the matter after I provided the TSB and CSP11 information. Mazda has declined financial assistance because my vehicle falls outside the applicable coverage period and has stated that its decision is final. I am submitting this complaint because I believe this documented cylinder head failure may represent a significant safety/reliability concern for other CX-9 owners, particularly if the condition develops shortly after the 10 year /120, 000 mile coverage limit. I believe and should be made aware of the potential for coolant loss, overheating, and engine damage and that NHTSA should review the scope and safety implications of this condition.
I was driving home from work and may car started overheating out of nowhere. I was stuck in traffic and white smoke was exiting my exhaust. I pulled over and all of my coolant leaked out of my car. Took it the shop and they said I had a cracked head and need a whole new engine. I seen that there was a warranty sent out for a problem with an exhaust manifold issue leaking coolant and that is exactly what caused my problem. I contacted Mazda and they said there is nothing they can do. I will have to hire a lawyer and file a class action lawsuit. I never recieved anything from Mazda regarding the issue. They should be paying for my car. I had zero issues until the day it faulted out. I am outraged that I had a great car then something that Mazda knew about cause me an issue.
The cylinder head on this 2018 Mazda CX-9 (Skyactiv-G 2.5T engine) cracked, allowing engine coolant to leak and intermix with engine oil, causing loss of coolant and catastrophic engine failure. The vehicle became undriveable in the first week of November 2025 at approximately 125,019 miles and has remained inoperable since; it was not in a crash and had to be towed. This matches a known, documented defect on Mazda's Skyactiv-G 2.5T engine: coolant leakage at the cylinder head near the exhaust manifold, leading to overheating and engine failure. Mazda issued technical service bulletin(s) addressing cylinder-head cracking and coolant intrusion, revised the cylinder-head casting (a superseding part number), and extended warranty coverage (program CSP11) for this specific concern. This vehicle fell just past the mileage cap of that extension. Safety risk: a cracked cylinder head causing coolant loss and engine overheating can produce sudden loss of engine power and overheating if it occurs while driving. No crash, fire, or injury resulted in this case. A formal dealer diagnosis is pending; the failed engine/cylinder head is being preserved and is available for inspection on request.
My passenger heated seats malfunction while I was driving. As I was driving on the highway I smelled something burning. I didn't know where the smell was coming from it was strong . Then while I'm driving on the highway my seat started to smoke a lot I got scared and pulled on side of the road. I realized my seat was the issue turned off the heated seats on the control. Step out the vehicle on side the highway I was nervous and scared standing outside my vehicle. The smoke eventually died down and cleared out. I never turned it back on and put a small piece of tape over the hole it burned through my seat.
My wife was driving the vehicle when the emergency lights started going off. She had to pull over because the car wouldn't run and said it was overheated. All the maintenance has been done to the car. We took it to the dealership and they said it is a cracked head and it is a known issue. They even issued a extended warranty for it. It is TSB 01-002/23. There should be a recall on this not just a partial credit.
My 2018 Mazda CX-9 with the SKYACTIV-G 2.5T engine has been diagnosed with a cracked cylinder head, cracked exhaust manifold, and cracked turbocharger at approximately 88,000 miles. This is a known design defect documented in Mazda TSB 01-002/23 and addressed by Customer Service Program CSP11, which extended the powertrain warranty to 10 years/120,000 miles for coolant leaks at the cylinder head. The TSB identifies exhaust manifold deformation and residual production stress as root causes of the cylinder head cracking. In my vehicle, the failure has extended to the exhaust manifold and turbocharger, both directly mounted to the cylinder head in the same high-stress zone. The turbocharger on this engine is a coolant-cooled unit. As coolant leaks from the cracked cylinder head, the turbocharger is deprived of its cooling supply, leading to excessive heat buildup and eventual cracking of the turbo housing. The turbo damage is a direct consequence of the cylinder head defect Mazda has already acknowledged. CSP11 covers the cylinder head but does not address consequential damage to the exhaust manifold and turbocharger caused by the same defect. I am requesting the NHTSA investigate whether Mazda's remedy is sufficient and whether a formal recall is warranted given the risk of sudden engine failure at highway speeds.
The liftgate (trunk) opens sporadically. The system keeps trying to open the truck and it's causing a parasitic drain on my battery. I was stranded 2 hours from my home due to this. My trunk would sporadically beep three times, that is the only warning I received. There are safety recalls for other year of Mazda cx-9 but not my specific even though I am having the same issue.
My 2018 Mazda CX-9 experienced catastrophic engine damage after a radiator failure allowed coolant to enter the engine. The vehicle provided no dashboard warning, overheating alert, or coolant warning before the failure occurred. Modern vehicles are designed to alert drivers to overheating or cooling system failures. The lack of warning prevented me from addressing the issue and resulted in catastrophic engine damage. I believe this represents a potential safety defect in the vehicle’s cooling system monitoring and warning system.
The adjustable rails holding the rear left seat in place no longer latch. It is available for inspection. This is the most common place for a car seat in this car. In the event of a crash the seat would slide forward. The seat belt attaches to the seat so there would be little restraint on the rear passenger. The mechanic who attempted a repair stated Mazda does not sell this part, only sells a replacement for the entire seat, about $5000. There were no symptoms, when adjusting the seat the rail just stopped holding the seat firmly in place when the adjusting bar was released.
Here the facts, bought a car out of state (Illinois) from Iowa with 130,131 miles on Sept 12th 2025, Mazda CX9, the dealer did not disclose any problems with the car, after 3 months of ownership, the car overheats on highway whit family including a [XXX] infant, white smoke under the hood and exhaust pipe, towed home, radiator was replaced, few days after that a coolant leak, vehicle was sent to an authorized Mazda dealership for diagnose, the technician told us, according to Mazda procedures, a cod P111A, the vehicle's engine reached unsafe level of temperature and the whole engine needs to be replaced because a cracked head cylinder. This problem is well known by Mazda because they addressed on a TSB01-002/23 and CSP11 extended warranty, there is a flaw in the design of the engine near the cylinders manifold area, that cracks the engine and requires a full replacement of the engine. its just a flaw in the design of the engine. This issue can appear at any point threatening the life of the occupants of the vehicle INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
