Recalls on the 2018 Mazda MAZDA3

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2023391 116,779 units in Canada

Visual System

Issue: On certain vehicles, a problem with the rearview camera connector could cause distortion or flickering of the rearview camera image. Note: This recall only affects hatchback (5-door) models. Safety Risk: A rearview camera image that doesn't display correctly could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash. Corrective Actions: Mazda will notify owners by mail and advise you to take your vehicle to a dealership to inspect the rearview camera and install a seal for the wiring harness. The dealer will replace the rearview camera, if necessary.

Recall 2021696 20,762 units in Canada

Fuel System

Issue: On certain vehicles, the fuel pump could fail. If this happens, the engine may run rough or may not start and the check engine light may turn on. This could also result in a sudden loss of engine power while driving. Safety Risk: A sudden loss of engine power while driving could increase the risk of a crash. Corrective Actions: Mazda will notify owners by mail and instruct you to take your vehicle to a dealer to replace the fuel pump.

Recall 2019169 51,682 units in Canada

Visual System

Issue: An electrical problem may cause the windshield wipers to stop working. Safety Risk: Windshield wipers that do not work could affect a driver’s visibility under certain conditions. This could increase the risk of a crash. Corrective Actions: Mazda will notify owners by mail and instruct you to take your vehicle to a dealer to replace the front body control module with an improved one.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

ELECTRICAL SYSTEM

In 2023, the reverse camera would either flicker or completely shut off (displaying a blank screen) while the reverse gear is engaged. While reversing the vehicle to park onto the property the rear camera image failed to display in the vehicle, leading to a collision with the curb. The limited visibility out of the rear windshield for the Mazda 3 leads to a typical driver relying on the camera display to show obstructions not visible through the rear and side mirrors. This failure lead to the car impacting the curb and the passenger being shocked that the car was in an accident. If that was child or small animal, they would have been hit or run over. Luckily, this failure only resulted in property damage, a large dent in the bumper, and possible exhaust damage (see attached). A recall notice for this known Mazda camera issue was sent out in the mail by the manufacturer at the end of 2023. Mazda failed to address the issue when inquired over the phone, instead stating they "Would be in contact once a solution was found." Mazda did not reach out or notify me at any point with a solution until the incident above occurred. After contacting Mazda by phone to address the issue, they said there is still no solution found but to take the vehicle down for a diagnostic test that would be the owner's responsibility to pay for if it was found to be a "owner issue". After a brief discussion and multiple phone calls, Mazda stated they would make the repair as it was confirmed to be a Mazda issue that had just been solved. However, the car would need to be kept over the weekend and a loaner vehicle would be provided. Mazda also stated the collision was a driver issue and Mazda will not be responsible for anything that occurs while using the vehicle. At that point, the dealership was unwilling to assist me and I left. This seems to be a Mazda originating issue, if the rear camera functioned as intended, the curb would have been visible and the impact could have been avoided.

VISIBILITY/WIPER

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.

VISIBILITY/WIPER

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.

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.

FUEL SYSTEM, GASOLINE

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.

POWER TRAIN

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.

POWER TRAIN

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 touch screen in my car has developed a malfunction known as “ghost touch,” where the screen glitches and registers inputs I am not making. This failure involves the infotainment system, and the component is still available for inspection upon request. My safety and the safety of others were put at risk because the screen can suddenly change settings, including navigation, phone, and climate controls, while I am driving, which is distracting and dangerous. The problem has not yet been reproduced or confirmed by a dealer or independent service center, nor has the vehicle been inspected by the manufacturer, police, insurance representatives, or others. There were no warning lamps, messages, or other symptoms before the failure—it began suddenly and recently without prior indication.

Liberty, SC

ELECTRICAL SYSTEM

There is a infotainment display that sits on the center part of the dash that has touch screen capability that over time starts to fail and results in what is known as "ghost touch", where random screen settings change as though someone is using the touch screen on the infotainment screen. I had issues to where settings for screen brightness have changed causing my ability to see the controls being hindered and the radio sometimes turning up loudly and then off causing a scare distraction while driving. This screen is also used for the back up camera. There is currently a class action lawsuit for this.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

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.

My screen ghost taps (goes into apps without me touching it) plus there is screen damage. I got into my car one day and it looked like the screen was cracked. But it’s on the inside. I never been into the car crash or had any accidents happen to my car or the display. It affects my driving when I am using my back camera

Touchscreen has the "ghost screen" problem. It has gotten progressively worse over the last year. The Mazda dealership did a firmware update about 2 years ago and that didn't help. Now the screen thinks it's being pressed constantly in the same spot so it just beeps over and over again. If I'm not on my radio, it will hit things like safety settings, emergency contacts, etc. so I have to leave my radio on all the time. I've researched this issue and it's well-known. A recall was issued for 2014-2016 models but not for anything after that.

Mazda had previously issued a Special Service Plan (SSP) to remediate issues with their Mazda Connect Center Display (infotainment system), specifically "ghost touches" and "spider cracking" of the screen: [XXX] This Special Service Plan only applied to 2014-2016 models of the Mazda3. I own a 2018 Mazda3 which has the exact same issue described in the above service plan. Searching online, I am far from the only person who is affected by this issue that continues to be present in newer models of the Mazda3. Mazda should replace my (and others) infotainment system, as it is unusable and distracting in it's current condition.

The entertainment/navigation screen randomly started developing spidering cracks on the inside of the screen and has grown exponentially. It is getting close to the point where the screen is not readable and becoming useless. I have done research and have seen that many other Mazda owners have experienced the same issue where their screens cracked from the inside rendering it useless but Mazda refuses to cover the cost of an issue that is not caused by any Mazda owner. Without this screen, I would need to hold my phone in order to use a navigation app to get around or attempt to find a phone holder so I can still get around successfully.

I have a letter for an important safety recall, re: the backup camera. The letter is dated September 2023, and I called today, after experiencing worsening deterioration of my camera, and I was told that there is currently no fix. So, after 1.5 years, I have no fix for my camera? This is a safety issue

Mazda has a warranty extension for the 2014-2016 Mazda 3 infotainment touch screen as it may malfunction and glitch. This glitch can be a distraction as the system believes that it is being touched and may cause many things to change in the car such as radio station, navigation setting, and even some vehicle setting accessible from the infotainment screen, causing distractions. However, this issue is also possible on newer 2017 and 2018 models, and there is currently no program to fix the issue. While Mazda may seem like this is not a safety as the touch screen is disabled above 5 MPH, it can still cause distractions when coming to a stop and while stopped which may result in an accident. I think this needs to be resolved and Mazda needs to acknowledge that this touch issue "Ghost Touch" can affect all Mazdas with Mazda Connect 1. Taking this to the dealership to fix is expensive as they want to replace the entire system at a cost of $1000, which I could see many people not doing leading to more dangerous vehicles on the road.
