2018 Mazda Mazda3 Problems

The center dashboard information screen developed "spider cracks" and got opaque in the corners of the screen. The screen would change functions / jump around commands without being touched while driving ( from NAV to radio, change radio stations etc) - apparently called 'Ghost Touch". Mazda has been aware of the defect for some time and issued a TSB ( and settled a class action lawsuit) but we never received any notification. The dealer offered no assistance as the car was out of warranty . We paid several hundred dollars to replace the screen as the car was becoming undriveable.

My 2018 Mazda 3 has an intermittent electrical failure on the high-speed CAN network that causes multiple safety-critical systems to fail while driving. When the fault occurs, the dash lights up with warnings for powertrain, ABS/traction, lane departure, collision-avoidance, TPMS, immobilizer, and the check-engine light. The car also hesitates or “lurches” between 15–30 mph during these events. At one point in 2024, the vehicle went into limp mode on the freeway, creating a safety hazard. These failures are intermittent but repeatable. Diagnostic scans from 2023–2025 show multiple U-codes for lost communication between control modules; two later became permanent. The issue appears unrelated to any one component and affects many systems at once. The vehicle has been to every Mazda dealership in the North Texas region (Mesquite, Freeman, Hiley, Norm Reeves, Town North). All performed only basic scans; none completed a full CAN-bus or wiring-harness diagnostic. Town North kept the vehicle for six weeks (Sept–Oct 2025), replaced a coil and spark plugs, performed a camera calibration and a TCM update, but the network failures returned within 38 miles. We sought independent inspection only after dealerships repeatedly refused diagnosis whenever the warning lights were not on at the moment of arrival. In November 2025, a technician found significant internal corrosion inside the negative battery cable; touching the cable reproduced the full failure immediately. The corrosion extends deep into the wire sheathing. This appears to be an electrical defect affecting CAN communication and power/ground integrity. When the fault occurs, multiple safety systems disable at once and the vehicle behaves unpredictably. Mazda Corporate has declined further assistance, and the defect remains unresolved. I am filing this report because this is a recurring safety issue that may affect other vehicles of the same model and year.

I got into my car and the infotainment screen was cracked. It had been parked in moderate weather (no extreme heat or cold) and just randomly had multiple small cracks across the screen. This makes the back up camera difficult to see which is a safety concern.

The Infotainment system is cracking uncontrollably and will make the rear view camera unusable and a safety issue. Mazda corporation wont pay for the repair that they are charging close to 2k to do.

The contact called on behalf of a customer who owns a 2018 Mazda Mazda3. The contact stated that the windshield wipers had become inoperable. The vehicle was taken to the contact's auto repair shop, Tire-Rama, where the windshield wiper switch was replaced; however, the failure persisted. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 19V272000 (VISIBILITY); and referred the customer to the dealer for assistance. The vehicle was taken to the dealer, who informed the owner that the vehicle was not covered under the recall because the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 200,000.

While I was driving on the highway, I went to use my front wipers and there was no response when trying to active them. The rear wiper, front and rear washer fluid sprayers all worked. No warning lights or other signs of failure were present. I took the car to a local repair shop and they diagnosed it as a bad Body Control Module. Once the module was replaced and reprogrammed, the wipers worked as intended. Safety Recall 3219D describes the issue I had perfecly. My VIN is out of the range of this recall but if I had the same issue as this recall, there might be other bad parts out there and that range might need to be increased.

What component or system failed or malfunctioned, and is it available for inspection upon request? The high-pressure fuel pump failed. This component failure prevents the car from starting or staying running. The check engine code confirmed the high-pressure fuel pump failure. The failed component is currently at the Mazda dealership and is available for inspection upon request. How was your safety or the safety of others put at risk The car suddenly stalled while driving on the roadway, creating a dangerous situation. If this had happened on the freeway or in fast-moving traffic, it could have led to a serious accident. Losing power and control of the vehicle at higher speeds poses a major safety risk to both the driver and surrounding vehicles. I was fortunate that the failure occurred on a city street rather than on the freeway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The Mazda dealership inspected the vehicle and confirmed that the high-pressure fuel pump had failed, which was also verified by the check engine code. This failure caused the stalling and starting issues. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by an authorized Mazda dealership, which diagnosed and confirmed the high-pressure fuel pump failure. It has not been inspected by police or insurance representatives. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Before the final failure, the car was hesitant to start, and after it stalled, the check engine light appeared. There were no prior warning messages or signs before the car suddenly stalled while driving. Additional details: The car is only seven years old with approximately 52,000 miles, and it is concerning that such a critical component would fail this early.

The contact owns a 2018 Mazda Mazda3. The contact stated that while the vehicle was parked, the contact became aware of a strong fuel odor around the exterior of the vehicle and inside the vehicle. The contact stated that the failure had occurred after refueling. No warning lights were illuminated. The dealer was made aware of the failure, and an appointment was scheduled for a diagnostic test. The dealer had to reschedule the appointment due to a scheduling issue. The vehicle was taken to an independent mechanic, where it was diagnosed with a crack in the top of the fuel pump. The contact was informed that the fuel pump needed to be replaced, and the vehicle was being repaired. The contact referenced an unknown recall with a similar failure; however, the VIN was not associated. The manufacturer was made aware of the failure and a case was filed. The contact was informed that the vehicle needed to be taken to a dealer for a diagnostic test. The repair coverage was denied because the vehicle was not repaired by a dealer. The failure mileage was 179,550.

I was parked in a downtown garage, and the vehicle would not start after many attempts, after about 45 minutes of trying (waiting 5 minutes between tries). The engine would turn normally and sounded like it was trying to start, but didn't fully engage. It finally did after 45 mins, and I drove it to the local Mazda dealer in Honolulu. I noticed the check-engine light was on at that time (but not before the incident). They ran a diagnosis, and couldn't replicate the issue, and said it may be a battery problem with low voltage, due to the engine's error codes. But I questioned that since the engine was able to turn normally and adequately at all starting attempts. And the battery was only 2 years old. So I replaced the battery at their recommendation. About 2 hours after picking up the car from the dealer, the same issue happened again. I recorded the issue on my phone this time, and gave it to the dealer. And this time I didn't want to chance it, so had the car towed back to the same dealer. They couldn't replicate the issue immediately, but after several attempts (over a day), they finally experienced it. They said the issue is the fuel pump. I am the original owner, and had purchased the car new from a Mazda dealership, and it has less than 26K miles on it. I researched previous recalls with this same issue on Mazdas, even the same year and model, and it appears to related: [XXX] [XXX] No one was physically harmed due to this issue, but it was certainly a safety risk. If the fuel pump fails while driving, the driver could lose control of the vehicle while in motion. I have attached the invoices for the repairs. I have contacted Mazda Customer Experience and they assigned a case number # [XXX]. However, I was informed that the repairs are unlikely to be covered as there is no open recall on the VIN regarding this issue. Thank you.

The rear brake pads on my 2018 Mazda 3 have worn out prematurely, thinning to as little as 2MM in just 40,000 miles, while my front brakes are still 6MM. Brand new brakes are 10MM. I have heard the exact same complaint from the owner of a 2016 Mazda 3, which is the same generation. In the majority of cars, front brakes are supposed to wear our faster than the rear, so this is definitely a problem. Further evidence of the problem is shown in the fact that my car tends to steer a bit left when pointed in a straight direction, even after getting alignment perfectly done, consistent with the fact that the driver's side rear brake pad has worn out the fastest. In short, the rear brakes seem to be clamping excessively or sticking to the pad when the brake pedal is disengaged, most intensely on the rear driver's side but also on the rear passenger's, thus wearing out brake pads prematurely, reducing fuel efficiency and creating excess environmental waste. This can also be a major safety hazard if the brake pads thin out well before a driver is expecting or if the brakes engage unexpectedly.

THE REAR WIPER STOPPED WORKING DURING A DRIVE IN HEAVY RAIN CONDITIONS, SIMILARLY LIKE IT HAPPEN TO THE SAME VEHICLE FOR THE FRONT WIPERS 6 MONTHS AFTER I GOT THE VEHICLE. I TRIED TO SCHEDULE AN APPOINTMENT WITH THE DEALER BUT WITH THE PANDEMIC IT WAS NOT POSSIBLE. WHEN I WENT FOR THE ACTUAL APPOINTMENT ON MARCH 2021, THEY TOLD ME THE VEHICLE WAS OUT OF WARRANTY EVEN THOUGH IT IS BARELY 3 YEARS OLD, AND JUST FOR A DIAGNOSTIC THEY WILL CHARGE $160 PLUS TAX. THE POTENTIAL REPAIR WOULD BE EXTRA, RANGING FROM A NEW BCM TO A NEW MOTOR, OR BOTH, SCALING UP TO $450 REPAIR BILL. THE ISSUE IS EXTREMELY SIMILAR TO A SAFETY RECALL THAT THE VEHICLE HAD FOR THE FRONT WIPER WERE THEY HAD TO CHANGE THE RELAYS FREE OF CHARGE. I CONSIDER THIS ALSO A SAFETY ISSUE AS IF YOU'RE DRIVING IN THE HIGHWAY AT 55MPH DURING THE HEAVY RAIN AND YOU ARE NOT ABLE TO SEE AND VEHICLE THAT COMES AT HIGH SPEED, SUCH TRUCK THAT LOOSE THE BRAKES IN A ROUNDABOUT EXIT, THAT POSES A SAFETY RISK TO DRIVERS AND OWNERS OF THIS VEHICLE. A RECALL SHOULD BE MADE FOR THIS REAR WIPER ISSUE LIKE FOR THE FRONT ONE.

I WAS DRIVING ON A VERY QUIET BOULEVARD IN NIAGARA FALLS, NY. I WAS THERE ON A FAMILY TRIP WHEN ALL OF THE SUDDEN WE HEARD MULTIPLE VERY LOUD NOISES COMING FROM THE TOP OF OUR CAR, ESPECIALLY THE LAST ONE WHICH SOUNDED LIKE AN EXPLOSION. THE SUNROOF OR OUR 6-MONTH OLD 2018 MAZDA 3 HAD JUST EXPLODED! WE PARKED TO CHECK WHETHER AN OBJECT HAD FALLEN INTO THE CAR BUT COULD NOT FIND ANYTHING, THANKFULLY THE INSIDE SUNROOF BLIND WAS SHUT BECAUSE MANY OF US COULD HAVE GOTTEN INJURED FROM GLASS PIECES FLYING EVERYWHERE INSIDE THE CAR OTHERWISE. NOW, TWO DAYS AFTER THE INCIDENT, OUR MAZDA DEALERSHIP IS CLAIMING THAT AN OBJECT MUST HAVE HIT THE CAR AND SAY THAT WE NEED TO SPEAK TO OUR INSURANCE. THEY DO NOT WANT TO DO ANYTHING ABOUT IT WHEN IT IS VERY CLEAR THAT IT IS A MANUFACTURING PROBLEM THAT COULD GET OTHER PEOPLE INJURED IN THE FUTURE. ONE OF THE REASONS I AM ABSOLUTELY POSITIVE THAT THIS IS A MANUFACTURING ISSUE IS BECAUSE WE HEARD ANOTHER VERY LOUD NOISE AND THE HOLE GOT SUBSTANTIALLY BIGGER WHILE PASSING BY THE SAME BOULEVARD LATER THAT NIGHT, MY WIFE LOST CONTROL OF THE CAR FOR A MOMENT AS IT HAPPENED. THIS IS A VERY SERIOUS AND SCARY SITUATION, WE HAVE SPOKEN WITH MAZDA CUSTOMER EXPERIENCE AS WELL AS WITH THE DEALERSHIP AND NOBODY WANTS TO TAKE RESPONSIBILITY EVEN WHEN THERE IS A CONSUMER REPORTS ARTICLE ON THIS AND 9 DIFFERENT REPORTS ON THIS ISSUE FOR MAZDA3 VEHICLES.

The TPMS light goes off when traveling over 50 MPH, indicating low air pressure on one or more tires. I pulled over, assuming I had a flat; upon visual inspection, everything looked normal. I drove to the nearest air station, checked all four tires, had the proper psi, and reset the TPMS; the light turned off. Then, 10 minutes into the drive, the TPMS light turned on again. I verified again that all tires had the recommended air pressure.

I PURCHASED A CAR OVER A YEAR AGO FOR MY SON FROM CRYSTAL AUTO MALL IN GREENBROOK, NJ, A MAZDA 3,2018. THE DAY AFTER I GOT THE CAR THE TIRE PRESSURE LIGHT CAME ON. I TOOK IT IN FOR SERVICE AND THEY ADVISED THAT NOTHING WAS WRONG WITH THE TIRE OR RIM. ON THE WAY HOME FROM THAT SERVICE VISIT THE TIRE LIGHT CAME ON AGAIN. MY SON COMMUTES SO THE CAR IS NOT USED ON A DAILY BASIS, IF IT SITS MORE THAN 2 DAYS THE TIRE IS COMPLETELY FLAT. THIS HAS BEEN A CONSISTENT ISSUE FROM THAT TIME UNTIL NOW. I HAVE TAKEN THE CAR IN FOR SERVICE SEVERAL TIMES FOR THIS SAME ISSUE AND THIS DEALERSHIP HAS BEEN COMPLETELY UNRESPONSIVE AND CARELESS ABOUT MY SITUATION. THEY HAVE NOT FIXED THE PROBLEM AND HAVE NOT ATTEMPTED TO REMEDY THE SITUATION. I AM DEEPLY CONCERNED ABOUT THE SAFETY OF MY SON AND OTHER DRIVERS WHO COULD BE POTENTIALLY HARMED BECAUSE OF NEGLECT BY THIS DEALERSHIP AND THE DEFECT AND OR ISSUE WITH THIS TIRE. YOUR ASSISTANCE IS APPRECIATED.

COMING OFF THE BQE IN NYC, ON A SHARP TURN EXIT RAMP LOST STEERING CONTROL. THE CAR VEERED SHARPLY TO THE LEFT INTO THE BARRIER CAUSING ALL THE SIDE AIRBAGS TO DEPLOY. LUCKY IT WAS AT A LOW SPEED SO NOBODY WAS HURT AND VERY MINOR BODY DAMAGE CAUSED. I HAD MY SON IN THE CAR, THE AIRBAG SAVED HIM FROM HITTING HIS HEAD INTO THE WINDOW. THE TOWTRUCK DRIVER SAID IT LOOKED AS IF THE STEERING FAILED BECAUSE THE STEERING COLOM DETACHED.

THE CAR WAS BEING DRIVEN BY MY WIFE IN THE RIGHT LANE ON 3 LANE WIDE I-95 SOUTH IN CONNECTICUT AT NORMAL HIGHWAY SPEEDS, APPX 55-60 MPH. ACCORDING TO HER, THE CAR LURCHED LEFT AT ALMOST 90 DEGREES AND IT WAS AS IF SHE HAD NO CONTROL OVER THE STEERING AND THE WHEEL WAS NOT TURNING LIKE NORMAL POWER STEERING TURNS THE WHEEL. SHE CROSSED OVER ALL THREE LANES, AND IT CRASHED INTO THE CENTER DIVIDER SO THAT THE LEFT DRIVER'S SIDE WAS DAMAGED FROM FRONT TO BACK. SHE SAID IT WAS AS IF SHE HAD NO STEERING CONTROL AT ALL. FORTUNATELY SHE WAS NOT INJURED. BUT THE UNEXPLAINED LOSS OF STEERING CONTROL SOUNDED LIKE THE PROBLEM EARLIER WITH THE TOYOTA. IF YOU HAVE RECEIVED ANY OTHER COMPLAINTS LIKE THIS, THEN THERE COULD BE A REAL PROBLEM. .

HEADRESTS TIP TOO FAR FORWARD. THEY CAUSE GREAT PAIN TO THE NECK, SHOULDERS AND BACK. PEOPLE HAVE RESULTED IN REMOVING THE HEADRESTS ALTOGETHER. IF THE VEHICLE CAUSES A PERSON PAIN, THEN THE VEHICLE IS NOT SAFE.

TL* THE CONTACT OWNS A 2018 MAZDA 3. THE CONTACT STATED THAT SHE WAS EXPERIENCING DIFFERENT ELECTRICAL FAILURES WITH THE VEHICLE. THE CONTACT STATED THAT THE PASSENGER SIDE SEAT BELT WARNING CHIME SOUNDED WHEN THE SEAT WAS UNOCCUPIED. THE CONTACT HAD TO BUCKLE THE SEAT BEAT TO STOP THE WARNING SOUND. IN ADDITION, BOTH PASSENGER SIDE WINDOWS FAILED TO ROLL UP AFTER BEING DOWN. ALSO, WHILE DRIVING 40 MPH, THE TRANSMISSION FAILED TO RESPOND WITHOUT WARNING WHILE DEPRESSING THE ACCELERATOR PEDAL. THE CONTACT HAD TO SHIFT THE VEHICLE FROM SECOND INTO FIRST GEAR IN ORDER FOR IT TO RESUME NORMAL OPERATION. THE CONTACT TOOK THE VEHICLE TO ODGES MAZDA AT THE AVENUES (10681 PHILIPS HWY, JACKSONVILLE, FL 32256, (904) 562-1600) WHERE A DIAGNOSTIC TEST WAS PERFORMED, BUT NO FAILURE WAS FOUND. THE FAILURE CONTINUED AND THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 18.
