ENGINE

In June of 2022 I started having a strong antifreeze/engine coolant smell inside the cab of my vehicle and also outside the vehicle. I had the car checked for a radiator leak, but there wasn’t one. I took my car into my local Mazda where they found that the engine coolant was leaking into the heads of the engine. Mazda kept my car for 5 months and repaired the problem, it cost me $4000 and they had added a 12 month 12,000 mile warranty for the parts. My car is a 2016 Mazda cx-9 at the time of the repair it had 70,430 miles on it. Now a few years later I am having the same issue with the coolant smell inside the cab and outside my vehicle, it goes into the shop for diagnosis on Monday November 10,2025. The car now has 118,000 miles on it. I had purchased an extended warranty for the car at the time of purchase but it had timed out a month before I took my car in for the first repair….please Mazda stand behind your vehicles I am a senior woman with very little income and I will not be able to pay out of pocket for this repair and I CANNOT afford a new car… I would like to get reimbursed for my out of pocket on the first repair and get my car repaired this time as well under a warranty.

Head gasket leaking and caused major engine issue at 89,000 miles. Mazda has known of this issue, but refuses to recall it.

While my wife was driving her 2016 Mazda Cx-9 Grand Touring on the freeway, many of the dashboard indicator lights came on warning her the engine was over heating and to pull over immediately. While she was attempting to move over to the shoulder, smoke appeared from underneath the engine hood which made it difficult to safely move over to the shoulder. She believed the car was on fire so immediately exited the vehicle along with her sister whom was pregnant. I arrived within minutes and noticed the engine compartment was smoking and coolant/engine oil leaking underneath the car. The car was towed to my local Mazda dealership where I was advised days later the engine needed to be replaced due to blown head gaskets. They advised the vehicle over heated causing oil and coolant leaking from cylinder head that is warped. This repair would cost $11, 179.29. Mazda service advisor also mentioned the radiator and lower/upper radiator hoses needed to be replaced. This repair would cost $2691.28. This incident could've resulted in serious injuries or death from a known issue with these engines by Mazda. It's only a matter of time before this failed engine turns into a fatality. Do the right thing Mazda and fix these engines. Your reputation is on the line.

Sudden and dramatic loss of engine coolant. Received a warning that engine was overheating, and to shut off engine. Quickly obeyed the prompt and found that most of the engine coolant had been lost due to a catastrophic failure of either the head gasket or head itself.

MY WIFE AND DAUGHTERS TOOK A TRIP, AND ON THE WAY HOME, THE ENGINE LIGHT CAME ON. WHEN TURNING ON THE ENGINE TO CHECK THE ENGINE LIGHT, I NOTICED THAT THE BRAKE PEDAL WAS HARD. I WAS THINKING THE ENGINE LIGHT HAD TO DO WITH THE GAS CAP NOT BEING ON TIGHT SINCE FAMILY PURCHASED GAS ON THE TRIP BACK HOME. I DROVE THE CX-9 TO AUTOZONE TO DETERMINE THE CODE FOR THE ENGINE LIGHT. THE ATTENDANT AT AUTOZONE WAS UNABLE TO REGISTER A CODE. HOWEVER, I NOTICED THE BRAKES FELT DIFFERENT ON THE DRIVE TO AUTOZONE. ALTHOUGH I HAD TO APPLY MORE PRESSURE TO STOP, IT TOOK LONGER TO STOP. IT ROLLED TO A STOP. WHEN I GOT BACK HOME, I HEARD A HISSING SOUND COMING FROM UNDER THE DASHBOARD. MAZDA'S OWNER'S MANUAL REGARDING THE ENGINE LIGHT INDICATES 1.) THE FUEL TANK LEVEL BEING VERY LOW, 2.) POSSIBLE ELECTRICAL SYSTEM PROBLEM, 3.) EMISSION CONTROL PROBLEM, OR 4.) FUEL FILLER CAP IS MISSING OR LOSE. THE NEXT MORNING I DROVE THE CX-9 TO SEE IF TIGHTENING THE GAS CAP WOULD CORRECT THE ENGINE LIGHT. DURING THE DRIVE, THE BRAKING SEEMED DIFFERENT. I WOULD PRESS THE BRAKE, BUT THE VEHICLE WOULD ROLL TO A STOP INSTEAD OF STOPPING. WHEN I WAS APPROACHING A CAR STOPPED AT A RED LIGHT, I HAD TO PRESS THE BRAKE VERY HARD TO AVOID THE VEHICLE. I PARKED IT AND CALLED THE LOCAL MAZDA DEALER. AFTER THEY PERFORMED A DIAGNOSTIC TEST, THE BRAKE BOOSTER WAS DETERMINED TO BE FAULTY. I WAS CONFUSED ABOUT HOW A BRAKE BOOSTER AND AN ENGINE LIGHT CORRELATES. I'M ALSO TRYING TO UNDERSTAND WHY THE BRAKE SYSTEM WARNING LIGHT WAS NOT ACTIVATED SINCE THIS RELATES TO THE BRAKING SYSTEM. AFTER ADDITIONAL RESEARCH, I'M IN COMPLETE DISBELIEF THAT MAZDA IS AWARE, AND IT HAS NOT DECIDED TO ADDRESS THIS SAFETY ISSUE. PLEASE TAKE ACTION TO HAVE MAZDA RECALL THE BRAKE BOOSTERS TO ADDRESS THIS ISSUE SINCE IT'S AWARE THE PROBLEM IS AN EQUIPMENT/MATERIALS ISSUE.

BOTH REAR BRAKES LOCKED UP ON SEPARATE OCCASION WHILE DRIVING ON THE FREEWAY AT ABOUT 70 MPH. EACH TIME THE BRAKE ENGAGED THEMSELVES AND LOCKED ONTO THE DISK/ROTOR. THIS CAUSED THE PADS TO BURN UP AND PRODUCE A LARGER QUANTITY OF SMOKE. ON ONE OCCASION THE ROTOR BECAME RED HOT, FLAME WAS VISIBLE, LOTS OF SMOKE WAS BEING PRODUCED, AND IT WARPED ROTOR. EVERY TIME IT OCCURRED I STOPPED THE VEHICLE AND TURNED IT OFF. AFTER THE RESTART OF THE VEHICLE THE BRAKES WERE NOT LOCKED BUT THE VEHICLE WOULD SHAKE AS NOW THE ROTORS WERE WARPED AN THE PADS WERE DESTROYED. I TOOK MY VEHICLE TO THE MAZDA DEALERSHIP AND THEY INFORMED ME THAT I NEEDED NEW PADS, I DID BUT IT WAS DUE TO THE REAR BRAKES LOCKING UP ON THEIR OWN. I GOT THE PADS REPLACED AND 6 MONTHS LATER IT HAPPENED AGAIN. THIS TIME I RECORDED A VIDEO ON MY PHONE AND SHOWED THE DEALER SHIP WHAT I EXPERIENCED AGAIN. THIS TIME THEY INFORMED THAT I NEEDED, NEW BRAKE PADS(AGAIN), ROTORS, AND PISTON BUT THEY DID NOT ADDRESS WHAT IS CAUSING THE REAR BRAKES ONLY TO LOCK UP ON THEIR OWN CREATING EXCESSIVE WEAR AND DAMAGE TO THE BRAKE COMPONENTS. SOMETHING IS AND CONTINUES TO ENGAGE MY REAR BRAKES. IT LAST OCCURRED ON 10-04-19 AND IT HAS ONLY BEEN 3 DAYS SINCE THE MAZDA DEALER REPLACED THE DAMAGED PARTS AND UNDER HARD BRAKING THE VEHICLE CONTINUES TO SHAKE WHICH ARE EARLY SIGNS OF WHAT HAPPENED BEFORE, SO ITS ONLY A MATTER OF TIME BEFORE IT OCCURS AGAIN.

I WAS DRIVING ON THE INTERSTATE AND THE TPMS WARNING CAME ON. I PULL OFF THE INTERSTATE AND PARK. THERE IS SMOKE COMING FROM THE RIGHT REAR WHEEL AND THE CENTER OF THE WHEEL IS EXTREMELY HOT, TOO HOT TO TOUCH. I CAN FEEL THE HEAT FROM ABOUT A FOOT AWAY. THERE IS METAL PINING AND GROANING AS IT COOLS DOWN, THE TIRE IS WARM, BUT NOT AS HOT AS THE CENTER A THE WHEEL. THE LEFT REAR WHEEL IS COOL TO THE TOUCH, AS ARE THE FRONT WHEELS. I TOGGLE THE ELECTRONIC PARKING BRAKE A FEW TIMES AND AFTER THE WHEEL HAS COOLED DOWN I DRIVE ON. THE PROBLEM DID NOT OCCUR AGAIN IN THE LAST 60 MILES, HOWEVER, THE RIGHT REAR WHEEL NOW MAKES A NOISE WHEN BRAKES ARE BEING APPLIED CONSISTENT WITH THE ROTATION OF THE WHEEL.

ONE MILE FROM HOME THE SMART BRAKE SYSTEM MALFUNCTION & FRONT RADAR SYSTEM MALFUNCTION WAS DISPLAYED. CAR WAS SHAKING AND ACTING AS IF THE EMERGENCY BRAKE WAS ACTIVE WHILE THE CAR WAS IN MOTION.

August 2nd I noticed a smell of Coolant coming from my car. I looked under my car and noticed it leaking green coolant. I took it to Mazda where they had it for 7 days to then give me a $6,300 estimate with possible added expenses. They diagnosed it as a cracked cylinder head and needs a gasket as well. I am a single mother and have work but I cannot afford that repair especially since Mazda is not going to honor there vehicle and what they stand by. With this issue with the coolant leak and the cracked cylinder the vehicle could have overheated and go into limp mode and come to a sudden stop with my children in the car while driving on the road. I could be hit as this puts my family at risk of injury while we go to school or work. Mazda has done nothing but tell me to submit a claim with customer service which I have. I had my case manager call me once and left a voicemail and I have called multiple times and have not heard back. There was no warning of this until I found forums and other stories that this unfortunately has happened to hundreds of Mazda owners.

While driving on the freeway in stop and go traffic the engine warning light came on. A few minutes later the data screen stated that I needed to pull over immediately as my engine was overheating. I was on a stretch of the 5 freeway north of Oceanside with no exits for several miles. I pulled over and when the light went off I got back on the freeway to try to make it to an exit. I repeated this process until I was able to exit and pulled in at the first mechanic I came to. The vehicle was losing power at that point. Pulling in and out of the traffic was hazardous to both me and the other drivers. When they inspected my car, they determined that the coolant had been leaking for a significant period of time as demonstrated by the worn spot on the pipe it had landed on. Further inspection revealed a blown head gasket. When a new head gasket was ordered from the local Mazda dealership, the mechanic was surprised to learn that Mazda had four of these parts in stock as most dealerships would have to order the part. The Mazda service department told him that they had four head gaskets in stock because this happens pretty often. My research on this site and on the Mazda forum indicates that this is a known defect to Mazda. This vehicle has just over 56,000 miles on it. It is regularly serviced. There was no warning light prior to this incident, in fact, the blue light indicating the engine was cool had regularly appeared whenever I started the vehicle. I have the replaced head gasket in my possession, should inspection of the part be necessary. I have reported this issue to Mazda but have been advised it is unlikely they will reimburse me.

At an intersection the engine stalled and car was extremely hard to restart (took several minutes). I later noticed oil and coolant dripping from the engine and coolant mist/vapor from the exhaust. Later I learned it was possibly related to Mazda's own TSB Bulletin No: 01-013/21 where a manufacturing defect caused coolant to enter the combustion chamber and hydro lock the engine (where I stalled and had hard time restarting). I had to have the car towed home. At home I noticed the passenger underside of the vehicle coated with oily/watery residue of possible oil or oil/coolant mix. Vehicle had 66K miles on and Mazda dealer refused to fix.

Dec 26, 2022

Due to Mazda's known problem in the design of their engine at just over 80,000 miles the head and turbo of my engine have cracked. They have issued a service bulletin to their dealerships, which acknowledges this as a common problem. (Technical Service Bulletins (TSBs) are official communications between Mazda & its dealerships that describe processes for troubleshooting or fixing certain common problems.) Unfortunately, for most Mazda CX-9 owners this bulletin was issued after most have just passed their 60,000-mile warranty, thus allowing them to get away with designing an engine for a fairly expensive car that is only good for 80,000 miles. Mazda further acknowledges this as a problem as newer engines are no longer designed the same way to avoid the problem and any parts put on the engines that are failing are of the new design because the OEM parts will just fail again. Dealing with Mazda customer service is a joke, they are rude, refuse to answer questions and will not call you back with answers when they say they will.

MY MAZDA CX-9 RAN OUT OF GAS ON A MAJOR HIGHWAY (ROUTE 90 IN BOSTON) AND THE GAS GAUGE READ HALF FULL. NO 'OUT OF GAS' LIGHT WENT ON AND RANGE (UNDER INFORMATION) SAID 191 MILES REMAINING. MY MAZDA DEALER TOLD ME THE SOFTWARE NEEDED TO BE RESET (NOT DONE YET AS OF THIS WRITING). IT IS A MAJOR ISSUE IF THE GAS GAUGE IS NOT READING PROPERLY AND THIS IS A SOFTWARE ISSUE (A BUG?). MAZDA NEEDS TO FIX THIS FOR ALL MAZDA'S AND ISSUE A RECALL SO IT DOES NOT HAPPEN AGAIN.

Feb 25, 2020

WHILE DRIVING THE CAR IN THE 287 INTERSTATE HIGHWAY IN NEW JERSEY, I GOT THE CHECK ENGINE LIGHT OUT OF THE BLUE AND THE CAR STARTED DECELERATING IN THE HIGH SPEED LANE. LUCKILY I WAS ABLE TO MANAGE AND GET THE CAR TO THE ROAD SIDE SHOULDER. I WAS NOT ABLE TO START THE CAR AFTER THIS INCIDENT. WE HAD TO TOW THE CAR TO THE MAZDA SERVICE CENTER IN GREENBROOK, NEW JERSEY. AFTER RUNNING THE CAR DIAGNOSTICS (ERROR CODE - P0192), THEY INFORMED ME THAT THEY HAD TO UPDATE THE PCM (POWER CONTROL MODULE) SOFTWARE. THATS THE ONLY EXPLANATION WHICH THEY GAVE WHICH MADE NO REAL SENSE. THEY DID NOT PROVIDE ANY INFORMATION WHY THIS ISSUE OCCURRED AND WHAT WAS DONE TO MAKE SURE THIS ISSUE DOES NOT OCCUR IN THE FUTURE.

Jan 14, 2020

I BOUGHT THE CAR SATURDAY. FOUR DAYS LATER, I FILLED THE TANK AT 2:00 PM FOR THE FIRST TIME. I THEN DROVE ABOUT 30 MILES. WHEN I ARRIVED HOME AT 5:00PM, I PARKED IN THE GARAGE. I NOTICED THE ODOR OF FUEL AS SOON AS I EXITED THE CAR AND CHECKED TO MAKE SURE I HAD SECURED THE GAS CAP, WHICH I HAD. THIRTY MINUTES LATER, THE ENTIRE DOWNSTAIRS OF OUR HOUSE SMELLED LIKE GASOLINE. THE GARAGE WAS CONSUMED WITH FUEL ODOR, AND THE FIRE POTENTIAL CAUSED US TO RETURN THE CAR TO THE DEALERSHIP IMMEDIATELY AFTER THAT. THE FUEL ODOR WAS PRESENT WITHIN THE CAR AS WELL.

Vehicle “surges” at idle. 300-500 RPMS at a time. Sometimes the brakes hold and sometimes not. Have nearly been in 3 collisions the last 2 days because of this issue. The ECM codes indicate throttle body or TPS issue, both of which have been unfounded. Vehicle has 63,000 miles. Researching this topic online found that many others have had this issue with no associated safety recalls noted. I am hoping to bring light to this so someone doesn’t have to be injured or killed to have this rectified.

Traveling on the highway going on a road trip. Had vehicle inspected prior and no fuel system problems were noted. I was going 75mph with my family when there was a coasting feeling in the car. I looked and my check engine light popped on and my car immediately would not accelerate and we quickly lost speed. By the grace of God were we able to pull over safely! Code P0132 was the engine code and after an hour, the engine light went back off and we were able to keep a safe speed traveling home. After speaking with a mechanic and dealership, I learned that this was a common problem with the Denso fuel system. My vehicle was not included in a recent recall that included a different year of my vehicle. If manufacturers are aware that a major defect is out there, how many people have to have an accident or potentially cause a huge accident because a car made 2 years prior with the same part from the same manufacturer has the same dangerous problem? It’s ridiculous and I hope you look at this near fatal issue that has effected thousands of people, whose vehicles’ were made in 2017, 2016, 2015 and are not included in the recall.

I took my car into the dealership and was told that I had a cracked cylinder head and the car is leaking coolant near the rear of the engine. This could cause the engine to cease should coolant get into the engine. The dealer (North Park Mazda, San Antonio) has confirmed this as the issue. I have received a video of the inspection from the dealership explaining the issue. The vehicle displayed a warning that it was overheating which is what prompted me to bring the vehicle in for service.

Our head gasket is needing to be replaced and sounds like this is an apparent Mazda problem how wide spread it is. The cost is over $5,000 for this single repair, possibly over $6,000 if head is cracked. I only have a parts list showing $1,700 in parts. Service manager said about 18 hours at $189hr totalling $3,402.

WHEELS

Rear wheel trim partially detached from car while driving, safety risk of large plastic part being caught in rear wheel. Did not hit any debris but heard a loud noise as the part detached. Part is supposed to be held in place by 12 clips but multiple owners of Mazda CX-5 and CX-9 models report this problem. Mazda dealers deny there is a problem even when some new cars have only 3 clips installed. When I called Mazda USA to report, and asked them specifically for a federal government contact to report safety issues, they said calling them was the ONLY way to report an issue, which was not correct. Was told I would have to pay for the repair of this safety issue. See this website for the experience of other owners and a description of the problem: https://mazdas247.com/forum/t/2016-cx-9-wheel-well-trim-became-detached.123861160/ I also personally know another Mazda owner who had the same issue with the part falling off while driving.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The entire electrical system is malfunctioning. All dashboard service lights (check engine, ABS, etc.) illuminate simultaneously, causing the vehicle to stutter and shut off while driving. The vehicle is available for inspection. 2. How was your safety or the safety of others put at risk? This issue has resulted in a dangerous situation, particularly when the vehicle lost power on the highway with my young children aboard. This sudden loss of control could have led to a severe accident. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Mazda’s service department has not been able to reproduce the problem despite multiple visits. I have provided video evidence, but no conclusive diagnosis or resolution has been achieved. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? Mazda’s authorized technicians have inspected the vehicle several times, but no substantial action has been taken. The vehicle has not been inspected by police or insurance representatives. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? All dashboard lights come on simultaneously without prior warning. The symptoms have been random and intermittent over the past few months. Given the ongoing risk, I request an immediate replacement of my vehicle. Please confirm receipt of this complaint and provide a plan for replacement. Thank you for your prompt attention.

I started smelling coolant after exiting the vehicle from a drive. Coolant level was very low. Adding coolant did not last long. I could not see where the leak was. The dealership evaluated and determined I had a cracked cylinder head and the car is leaking coolant near the rear of the engine. This could cause the engine to seize should coolant get into the engine. The dealer (New Rochelle Mazda) explains the cylinder head needs replacing. The dealer also observed bad rear sway bar links. One was detached. The car is serviced at the same dealership every 5k miles. The car has approximately 85k miles. The cylinder head has been repaired by the dealer under the extended warranty. Safety risk was moderate as the car could have stalled on the highway. The component was inspected by the warranty company and dealer only. The only warning lamps that showed up once were both brake indicator lights came on and the climate control would not warm the car.

As I am accelerating to merge onto the highway from an on-ramp, while the gas pedal is depressed, I will get a series of sensor alerts simultaneously (city brake malfunction, park assist malfunction, lane assist malfunction, etc.) and my gas pedal becomes non-functional at 60-70mph. It is terrifying especially when there is other traffic around my vehicle. This exact issue has happened 6 times within the past 12-18 months at seemingly random intervals but always when I am accelerating onto the highway at 50-70mph. I typically pull off to the side of the highway and turn off the vehicle. After letting it sit off for ~30 seconds, I turn the vehicle back on and all of the sensor alerts have cleared and the vehicle functions properly including the gas pedal and I am able to rejoin the highway. I took the car to the Mazda dealership in my state of Vermont a few months ago to have them diagnose and address the problem. They had never heard of this issue and were unable to find the root cause or fix it. Please help, this is dangerous!

Intermittent Airbag Warning Light (Code 18), Passenger Airbag Deactivation light not operating and no warning chime indicating unbuckled passenger side seat belt. The safety issue appears to be related to the airbag and related safety equipment. In the dash, within the speed and rpm display, the red airbag warning light is blinking, reporting from what I gather is a CODE18, as it blinks once, followed by a pause, followed by eight blinks. It appears to be linked an inoperable PAD warning light, which should be on while no one is sitting in the passenger seat and off while someone is sitting on the passenger seat. While the car is running and a passenger sits unbuckled on the passenger seat there is no warning chime indicating that this passenger is unbuckled. Thank you

On 04/21/22, I took my car to the dealer after noticing antifreeze on our garage floor and a burning smell. NO check engine lights had illuminated. They proceeded to tell me that there was a coolant leak from head/block and cavity leak (something about channel pressure). They also stated this was a casting flaw during manufacturing of the engine. They told me I needed a whole new engine for $8,479.97! Mazda corporate refused to replace the engine at their cost because I had 64,575 miles on it and it was out of powertrain warranty. I called them and asked to speak to a supervisor and never heard from them. I called on 4/26, 4/27, 4/28, 5/4, 5/5 (5 times), 6/9, & 6/20. I finally gave up agreed to pay $7,479.97 (the dealer gave me $1,000 off). I received the car back on 05/20 and it would not start later that day. They towed it back to Mazda and they replaced the crankshaft sensor that was damaged upon install of the new engine. I received it back again on 05/31 and later in the day, the check engine light came on and the automatic braking system engaged while I was driving (thankfully only 40 mph). I managed to pull over in a turn lane before the engine died. I was so thankful I did not make it onto the interstate I was about to enter! Mazda came and picked me up and later got my car. They could not figure out why it was dying and finally got it to recreate it. They replaced another engine sensor and then drove it a lot to make sure it was truly fixed. I finally received my vehicle back on 07/07. I am afraid to take my car out of town and it makes me nervous it will die and automatically start braking again. They KNOW this is a manufacturer issue and they refuse to take responsibility. I am so disappointed in them. This is a huge safety issue. I am also lucky I didn't blow a head gasket before I took it into the shop the first time.

However no intimation about the failure was mentioned or no further action taken about safety of other tires previously on the vehicle The incident took place suddenly with a huge noise due to the broken tire hitting the wheel well and ripping off the fender.

I JUST PURCHASED MY VEHICLE ABOUT 3 MONTHS AGO. I WAS RUNNING ERRANDS ABOUT A WEEK AFTER PURCHASE AND WAS HEADING HOME ON THE HIGHWAY WHEN THE GAS NOTIFICATION CAME ON DISPLAYING 27 MILES LEFT AND ADVISED ME TO GET GAS. I WAS ABOUT HALF MILE FROM THE EXIT AND THE VEHICLE CHECK ENGINE LIGHT CAME ON AND IT STARTED STALLING. THANK FULLY I WAS ABLE TO GET OVER TO THE MEDIAN JUST IN TIME WHEN IT SHUT DOWN COMPLETELY. I CALLED ROADSIDE AND THE DEALER AND EXPLAINED WHAT HAPPENED. I HAD IT TOWED BACK TO THE DEALER AND THEY ADVISED ME IT WAS BECAUSE I RAN OUT OF GAS. I EXPLAINED IT HAD A QUARTER OF A TANK AND DISPLAYED 27 MILES LEFT AND IT DIDN'T EVEN GIVE ME 1 MILE TO GET OFF THE EXIT. IT HAPPENED TO MY HUSBAND AS WELL RECENTLY AND I SPOKE TO A CERTIFIED MAZDA DEALER AND THEY EXPLAINED IT COULD BE THAT THE GAS TANK HAS A DENT CAUSING THE READING TO BE OFF OR ONE OF TWO FLOATS COULD BE DAMAGED AND NOT READING CORRECTLY. I WAS ADVISED THIS WAS A COMMON ISSUE WITH MY YEAR BUT IT'S NOT ON A RECALL. I USUALLY GET GAS WHEN IT HITS A QUARTER OF A TANK BUT NOW I'M AFRAID THAT I DO IT AT A HALF A TANK. THIS SHOULD BE A RECALL PROBLEM AS IT CAUSES THE CAR TO STALL IMMEDIATELY WHICH IS DANGEROUS. I HAD KIDS IN MY VEHICLE IN AN ICE STORM...I NEED TO HAVE THIS FIXED BUT IT'S WELL OVER $800.

IN 2017, MY CAR SHUT OFF TWO TIMES, WITHOUT WARNING, ONE TIME AT A STOP LIGHT AND AGAIN ON THE HIGHWAY GOING 70MPH. WE WERE ACCELERATING AT THE STOP LIGHT WHEN IT SHUT OFF AND THEN DRIVING ON THE HIGHWAY. TOOK THE CAR TO THE DEALERSHIP AND 72 CODES CAME UP. THEY SAID IT WAS THE DVD PLAYERS (THAT THEY SOLD AND INSTALLED!!!) THAT WERE CAUSING THE ISSUE. THEY SUPPOSEDLY 'FIXED' THE ISSUE. NOW IN JULY 2019, THE CAR SHUT OFF AN ADDITIONAL FIVE TIMES. THREE TIMES WHILE DRIVING AND TWICE IN A PARKING LOT. WE WERE ON A HIGHWAY AGAIN WHEN THE CAR JUST SHUT OFF WITH NO WARNING, LIGHTS ON THE DASH STARTED FLASHING, AND THE POWER STEERING WENT OUT ONE OF THE TIMES. MY HUSBAND HAD TO PUT IT IN NEUTRAL, COAST TO THE SHOULDER, COME TO A COMPLETE STOP AND THEN ATTEMPT TO START IT EACH TIME. CARS WERE DODGING US EVERY TIME AND LUCKILY WE WEREN'T HURT. MY CHILDREN WERE IN THE VEHICLE EVERY SINGLE TIME. WE HAD THE CAR TOWED TO THE DEALERSHIP WHERE 68 CODES CAME UP. THIS TIME THEY'RE SAYING IT'S THE FUEL PUMP AND THAT THEY CAN 'FIX' IT, BUT CAN'T 100% GUARANTEE IT WON'T HAPPEN AGAIN. WE WERE PUT IN A LIFE THREATENING SITUATION EVERY TIME, WITHOUT WARNING, AFTER GIVING THE DEALERSHIP A CHANCE TO FIX IT. THE CAR IS UNDER THREE YEARS OLD AND ONLY HAS 30,400 MILES ON IT.

DRIVING TO WORK IN THE MORNING AT 5:45AM ON 06/05/2018 GOING 65 MPH AND MY CAR CUTS ENGINE POWER AND STARTS LOWLY DECLINING PRESSING GAS DID NOTHING AND MULTIPLE NOTIFICATIONS FLASHING SUCH AS VEHICLE SYSTEM MALFUNCTION, FORWARD SMART CITY BRAKE SUPPORT MALFUNCTION, SMART BRAKE SYSTEM MALFUNCTION. I HAD TO PULL OFF TO THE SIDE OF THE HIGHWAY I CAN'T EVEN SAY I CAN PULL OFF SAFELY BECAUSE ALL POWER WAS CUT. SO LET THE CAR SIT FOR 5 MINUTES WHILE OFF AND THEN RESTARTED AND WAS ABLE TO MAKE IT WORK. I TOOK PICTURES AS EVERYTHING WAS HAPPENING BECAUSE I KNOW THE DEALER SHIP WILL SAY SOMETHING LIKE "WELP IT AIN'T HAPPENING HERE SO YOUR CAR IS FINE." I AM VERY FORTUNATE WHEN I BOUGHT THE CAR I DECIDED TO LEASE THE VEHICLE SO I CAN JUST TAKE THE CAR BACK. THESE MALFUNCTIONS SEEM LIKE A VERY SEVERE PROBLEM AND I DO NOT WANT TO HANG ON TO THE VEHICLE. ONCE 30K PASSES I WILL BE SUPER SCREWED! I CALLED DEALER SHIP AND THEY ARE BOOKED OUT 2 WEEKS SO I CANT EVEN TAKE THE CAR IN RIGHT AWAY, PLUS THEY AREN'T EVEN SURE IF THEY'LL HAVE A RENTAL FOR ME WHEN I DROP IT OFF. ALSO TO MENTION, AC UNIT ALREADY HAD TO BE REPLACED, AND A SUSPENSION RECALL. WORSE CAR I'VE HAD SO FAR ITS SUCKS BECAUSE MAZDA USED TO BE SO GREAT. THEIR SERVICE DEPARTMENT SUCKS BIG TIME! I NEVER HAD THIS TYPE OF SERVICE OR ISSUES THIS SEVERE WITH MY CHEVY. 08/07/2018 I TOOK CARE IN AGAIN FOR SAME SITUATION ALONG WITH AC AND ALL MAZDA TELLS ME IS THEY ARE LOOKING INTO AND ASSURE ME IT WILL BE TAKEN CARE OF THIS TIME. (ALSO SAID LAST TIME) I THINK THAT THEY DO NOT KNOW HOW TO FIX THE ISSUE! I CALLED CORPORATE TO ASK FOR A REFUND AND GIVE THE CAR BACK AND ALL THE TOLD ME WAS TO GIVE DEALERSHIP ANOTHER CHANCE TO FIX THE ISSUE. IT IS SO UNSAFE TO DRIVE AND HAVE KIDS IN THE CAR, I AM VERY FORTUNATE TO NOT HAVE MY BABY NEPHEW AND NIECES WITH ME WHEN THESE THINGS WERE HAPPENING.

THIS INCIDENT HAPPENED ON 31ST JULY, WHEN MY WIFE WAS DRIVING THIS CAR ON HIGHWAY 4 MARTINEZ, CA AT AROUND 5.00 PM WITH OUR DAUGHTER (2 YEARS OLD) RETURNING FROM DAYCARE. SHE WAS DRIVING AT APPROX 60 MILE/HR, WHEN THE CAR STARTED GIVING AUDIO VISUAL WARNINGS ON MULTIPLE FAILURES AND THE CAR STARTED SLOWING DOWN WITHOUT RESPONDING TO THE GAS PEDAL AND ENGINE PROPULSION REDUCED TO 'ZERO'. MY WIFE PANICKED AND WAS LUCKILY ABLE TO PULL OVER ON THE CURB SIDE SAFELY, EVEN THOUGH TRAFFIC WAS VERY HIGH. SHE STOPPED THE CAR AND TURNED OFF THE ENGINE AND WAITED FOR 10 MINS AND RESTARTED THE CAR MULTIPLE TIMES AND MADE SURE THAT NO MORE WARNINGS ARE DISPLAYED, BEFORE DRIVING AGAIN, HOWEVER THE 'ENGINE WARNING LIGHT' STAYED ON. AFTER A WHILE SHE DROVE HOME ALMOST 40 MILES AWAY VERY CAREFULLY WITHOUT USING ANY CRUISE CONTROL. HERE ARE THE WARNINGS, THAT CAME ON DURING THIS FAILURE, PICTURES ATTACHED. ENGINE MALFUNCTION LIGHT. TIRE PRESSURE INDICATOR. STABILITY CONTROL INDICATOR. TEMPERATURE INDICTOR CRUISE CONTROL FAILURE WARNING MESSAGE 'FRONT RADAR SENSOR SYSTEM MALFUNCTION' WARNING MESSAGE 'FORWARD SMART CITY BREAK MALFUNCTION' AFTER A DAY WE DROPPED THE CAR TO MAZDA DEALERSHIP FOR INSPECTION AND THEY FOUND MULTIPLE FAILURE CODES AND THEY DID NECESSARY REPAIR (INSPECTION AND REPAIR INVOICE ATTACHED). EVEN BEFORE THIS INCIDENT , WE REPORTED MULTIPLE TIMES TO DEALERSHIP THAT THE CAR CENTRAL INFORMATION SYSTEM ABRUPTLY SHUTS DOWN DURING DRIVE. BUT THEY ALWAYS SAID THAT THERE WAS NO PROBLEM. THIS INCIDENT ON A FREEWAY WAS VERY SERIOUS, MY FAMILY OR OTHER DRIVERS COULD HAVE BEEN IN A INJURY ACCIDENT BECAUSE OF THIS ISSUE WITH MAZDA.

WHEN DRIVING AT 35-50 MPH, MY 2016 MAZDA CX-9 PERIODICALLY BRAKES SUDDENLY WHILE DRIVING TO A SCRUBBING FORCEFUL STOP TOSSING THINGS OFF THE BACK SEAT, PLACING ME IN DANGER OF A REAR-END COLLISION. SOMETIMES A VERY QUICK BEEPING SOUND IS MADE, "B-R-A-K-E" APPEARS ON THE PANEL IN LARGE LETTERS --- THEN THE CAR AUTOMATICALLY COMES TO A SUDDEN STOP OR IT OCCURS WITH NO NOTICE. I HAVE TAKEN IT TO THE DEALER 3 OR 4 TIMES ONLY TO BE TOLD THAT THEY COULD FIND NOTHING WRONG. NO OBJECTS OF VEHICLES WERE IMMEDIATELY IN FRONT OF ME AND THE SENSOR WAS CLEAN WHEN THIS HAS OCCURRED.THIS SUDDEN STOPPING HAS OCCURRED ON THE FREEWAY, IN RUSH HOUR TRAFFIC AND ON CITY STREETS. THIS HAS OCCURRED AT LEAST 6 TIMES SINCE PURCHASED 03/17/17. I AM FEARFUL THAT THIS PROBLEM WILL RESULT IN INJURY OR DEATH TO ME AND OTHERS.

IMMEDIATELY UPON MAKING A SHARP RIGHT TURN INTO A PARKING SPOT, THE CAR SUDDENLY ACCELERATED AT A VERY FAST PACE WITHOUT ME PUSHING THE GAS PEDAL. MY IMMEDIATE REACTION WAS TO PRESS ON THE BRAKE, BUT IT DID NOT STOP. THE CAR SLAMMED INTO A PLANTER IN FRONT OF ME. THE CAR MOVED SO QUICKLY THAT IT WAS LODGED INTO THE BUSHES AND HAD TO BE PULLED OUT BY A TOW TRUCK. I IMMEDIATELY CALLED THE DEALER SERVICE DEPARTMENT AND TOLD THEM WHAT HAPPENED. THE SERVICE MANAGER'S IMMEDIATE REACTION WAS TO SCOFF AT THE IDEA THAT THE CAR ACCELERATED ON IT'S OWN. MY HUSBAND MET ME AT THE DEALER AND HAD SUBSEQUENTLY FOUND INFORMATION ABOUT A RECALL OF CX-9 MODELS FROM 2012 FOR A SIMILAR MALFUNCTION. HE SHOWED IT TO THE SAME MANAGER WHO IMMEDIATELY KNEW THE ISSUE OF THE RECALL BUT WAS QUICK TO MENTION IT WAS THE 2012 MODEL, NOT THE 2016. THE DEALER KEPT THE CAR FOR A FEW DAYS AND TOLD ME IT WAS DRIVEN TWICE AND ALSO SOME INFO FROM THE COMPUTER WAS REVIEWED WITH MAZDA TECH SUPPORT PERSON. NO DATA INDICATING ANY KIND OF MALFUNCTION IN THE CAR AND THE SERVICE GUY DID NOT HAVE A PROBLEM WITH IT IN TWO SHORT TEST DRIVES, SO THEY SAID COME PICK IT UP IT'S SAFE TO DRIVE. HOWEVER, I WILL NEVER DRIVE THIS CAR AGAIN. THIS IS THE FULLY-LOADED SIGNATURE CX-9 THAT THEY FEATURE IN ALL THEIR ADS. I LOVED THIS CAR AT FIRST SIGHT AND DROVE IT OVER 24000 MILES IN LESS THAN 2 YEARS. THIS EXPERIENCE SCARED ME TO THE POINT THAT I WILL NEVER DRIVE THIS OR ANOTHER MAZDA AGAIN. I HAVE HAD OVER A WEEK TO PROCESS THIS EXPERIENCE AND AM JUST HAPPY MY KIDS WEREN'T IN THE CAR OR THAT I DIDN'T HIT SOMEONE. I HAVE FOUND SEVERAL OTHER INSTANCES OF SUDDEN UNINTENDED ACCELERATION ONLINE AND CANNOT BELIEVE THAT THIS HAPPENS IN 2017. I HOPE THAT THIS DOCUMENTATION HELPS SOMEONE ELSE IN MY SHOES FEEL THAT THEY ARE NOT CRAZY AND THIS DOES HAPPEN. SHAME ON MAZDA FOR NOT FULLY ADDRESSING THIS ISSUE.

THE PUSH BUTTON ON/OFF SWITCH DOES NOT PROTECT AGAINST TURNING THE VEHICLE OFF IF TRANSMISSION IS ACCIDENTALLY LEFT IN ANY POSITION OTHER THAN 'P'. FOR EXAMPLE ITS POSSIBLE TO PUT THE TRANSMISSION IN 'R' AND TURN THE VEHICLE OFF. FOR A BUSY PARENT (TARGET DEMOGRAPHIC OF THIS VEHICLE), THIS IS VERY DANGEROUS. IF ON AN INCLINE, THE VEHICLE WILL START ROLLING FORWARD OR BACKWARD (DEPENDING ON INCLINE/SLOPE AND R/D TRANSMISSION POSITION). THERE SHOULD BE A SAFEGUARD OR A BEEP/WARN SYSTEM TO PROTECT THE DRIVER/OCCUPANTS THIS HAPPENED TO ME ON AN INCLINED DRIVEWAY WHEN I ACCIDENTALLY LEFT TRANSMISSION IN 'R' AND TURNED VEHICLE OFF. I TOOK FOOT OFF THE BREAK AND GOT OUT AND REALIZED VEHICLE WAS ROLLING BACKWARDS.

AFTER A MINOR REAR END ACCIDENT, THE DRIVER FRONT SEAT NOW ROCKS SIDE TO SIDE AND IS DISTRACTING AND UNSAFE. IT WAS TAKEN TO THE LOCAL MAZDA DEALERSHIP THAT PROVIDED AN INSPECTION AND SAID THAT THERE IS NO PROBLEM WITH THE SEAT. THEY STATE THAT IT IS NORMAL FOR THEIR SEATS TO ROCK SIDE TO SIDE. HOW UNSAFE AND FRIGHTENING. PLEASE SEE ATTACHED DOCUMENTATION FROM THE DEALERSHIP.
