MAZDA Complaints

My 2024 Mazda CX-90 MHEV has experienced multiple life-threatening sudden engine stalls and a complete loss of motive power while driving in active traffic lanes. The first incident occurred on December 31, 2024, when the vehicle abruptly shut down with an "Engine Malfunction" dashboard alert. The vehicle was towed to an authorized Mazda dealership (Palatine, IL), where it was held for a week, but technicians stated they could not replicate the issue and returned the car to me as safe. On March 30, 2026, the exact same failure recurred. While driving, the engine suddenly shut off completely at a traffic intersection. After turning the vehicle off for 5 minutes, it was restarted and driven to another authorized Mazda dealership (Crystal Lake, IL) for specialized diagnostic scanning. The second dealership successfully retrieved stored diagnostic trouble code (DTC) P061B, which is directly linked to safety recall 24V-815 (Loss of Drive Power from Software Errors). Crucially, the detailed diagnostic scan revealed that this code was historically stored with a timestamp dating back to December 2024. This proves that the safety defect was active and detectable during the first dealer visit 16 months prior, but was completely missed by the first dealership, leaving my family with an ongoing crash hazard. To address the failure, the dealership replaced the low-pressure fuel pump in the fuel tank and a mass airflow (MAF) sensor. However, Mazda Corporate customer experience has formally stated to me in writing that they are "not in a position to guarantee the concern will not reoccur." Because this safety-critical propulsion failure causes the vehicle to suddenly die in traffic and has a documented history of ineffective recall remediation, it poses an unresolved, severe crash risk. The vehicle is currently in my possession and available for inspection.

Mazda and NHTSA have sent out multiple notices calling owner to go to dealers to have the recall remediated. If one schedules to go to a dealership they are informed that Mazda does not yet have a tool available to remedy the issue. I've been on a waiting list for over 4 months and no tool is available yet. Since this appears to be a software issue it's very concerning that it's taking this long to create a "tool" to resolve an airbag issue.

The contact owns a 2016 Mazda Mazda3.The contact stated that while driving at various speeds, the contact stated that the vehicle's steering wheel would fail to operate as needed. The contact stated that an abnormal, clunking noise would emit from the steering wheel while turning at various speeds. The contact also stated that the steering wheel felt loose while driving at high speeds, fearing that he would lose control of the vehicle if he did not firmly grip the steering wheel. The contact had taken the vehicle to a dealer where they acknowledged that the heard the noise coming from the vehicle; however, they could not duplicate or diagnose the failure. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. the failure mileage was approximately 117,000.

Sunroof blew out while driving down interstate highway. There was no impact that we are aware of, just a complete failure of the sunroof glass. The sunroof was closed, with the shade also closed, so no glass fell down into the vehicle. The glass blew out with a very loud explosion that startled and disoriented all within the vehicle causing us to swerve and look around for what had happened. The glass has been inspected and is being repaired by a local auto glass shop today. No warning lamps or otherwise. I have pictures of the glass if needed.

Unintended acceleration incident. I entered the parking lot of a business where the Salvation Army is located to drop off a donation. The parking spaces were on the left side. As I pulled into a parking space and was in the process of parking, the vehicle suddenly lurched/accelerated forward unexpectedly and struck the concrete wall of the building. The airbags did not deploy despite the frontal impact. No one was seriously injured, but my husband, daughter, and I experienced soreness the following day from the impact. Thankfully, I had chosen a parking space in front of a concrete wall rather than the glass storefront windows, which could have resulted in far more serious injuries or damage. I contacted my insurance company, and the vehicle has since been repaired.

2023 Mazda cx50 has a leaking panoramic sunroof and was noticed on February 27th, 2026 after a hard rain. Got an appointment with my dealership on March 4th, 2026 I bought my car through, they denied helping me of any kind and diagnosed my car with a cracked sunroof bypass drain plug and the part can’t be replaced, the entire panoramic assembly needs to be replaced. I believe this is a safety issue and Mazda Corporate will not help either. Water should not be coming into my car with electronics at risk!

My 2021 Mazda CX-5 is experiencing excessive oil consumption. The vehicle is burning oil between regular oil changes, and the oil level drops noticeably before the recommended service interval. I have noticed a burning smell and/or signs of oil loss without visible leaks. This raises concerns about potential engine damage, stalling, or fire risk while driving. The issue has occurred repeatedly and does not seem normal for a vehicle of this age and mileage. I am filing this complaint because this may indicate a defect affecting engine safety and reliability.

This 2019 Mazda CX 5 is experiencing a crack in the oil cylinder. THis appears to be connected to: There is no official, broad NHTSA recall for cracked oil cylinders in the 2019 Mazda CX-5, but Mazda has issued a Technical Service Bulletin (TSB #SA-031-21) to address this known issue. It affects certain 2018–2021 CX-5s, particularly those with 2.5L engines, where a cracked cylinder head leaks coolant or oil. If this is a known issue with this vehicle, why has a recall not been addressed?

When turning on the heater or AC, the car blows out a coolant smell out of the vents. It does it every time the heat is turned on or switched over to AC. We have another appointment with the dealership to have this looked at, as well as many other issues we're having with this vehicle.

The car thinks the key fob is inside the vehicle when it is not. If you get out of the vehicle it will not self lock even if you have that feature set up. It will also beep consistently for about 10 seconds when you press the lock button on the key fob when your outside of the car, indicating that there is a key fob in the car....but there is not. The most concerning thing is you can get into the car and start it without any key fob inside the vehicle. It always thinks the key fob is in it, at all the time and will start without any key fob in it. This is not an occasional thing. It has been like this since we pirchased it from Mazda as a CPO vehicle. It's been doing this for all 2 months that we've owned it. We currently have an appointment with the dealership to take it in for them to hopefully fix it as well as other issues.
