2024 Mazda CX-90: fuel pump failure

Filed Jun 29, 2026 · Fuel system, Suspension · TN

The lower fuel pump is going out. It is a known issue with the car. I was driving out of town and the car started to stall. My steering has become ruggish while on the trip as well, and steering was complicated during heavy winds. The car has been inspected by dealer and both warning lights have been cleared. But the issues still remain.

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.

While my wife was driving my 2024 Mazda CX90 gas turbo at the posted speed limit, this vehicle suddenly without warning the car lost most of its power. She was able to move the vehicle to safety by pushing the gas pedal to the floor and achieved a maximum speed of 10 mph. The car was towed to the dealer Koch 33 of Easton, PA. The dealer diagnosed the problem as a throttle body issue. This is the second incident whereby this vehicle lost power in a similar manner but for a different reason (fuel pump) and had to be towed to the same dealer. I filed a complaint with your agency about 18 months ago. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I bought a brand new 2024 CX90 in May 2025. I was on the on-ramp entering a Highway at an accelerating speed when the car all of a sudden went into a limp mode and was unable to accelerate. This limp mode that kicked in almost caused me to be hit from behind. Immediately on the dash it flashed Engine Malfunction. I had to pull over to the side of the highway and had the car brought to my local Mazda Dealer. My local Mazda dealer stated that the recent recall #25V‑568 NTSHA caused the program/software for the car to misread my fuel pump and essentially burned out my fuel pump, and therefore breaking my fuel pump. They said they called Mazda, and Mazda is denying the fix because there is "no release date". Since Mazda is refusing to fix this, my local dealer says I have to drive the car as is. However, this is unsafe to drive. I paid for a brand new car only for it to have tech issues with Mazda refusing to do any fixes. This is our family car and I drive around with young kids. This is very unsafe to drive and Mazda needs to remedy this siutation immediately.

The vehicle displayed "Engine Malfunction have your vehicle inspected" on the dash along with orange lights. The vehicle would drive but without warning would not come up to speed. This caused an unsafe situation entering the interstate where the vehicle was below the minimum speed until we could exit the highway. There was no warning of the low power and inability to operate normally. This was a known problem and the vehicle had all of the recalls already performed. Dealer states there is a problem with the low pressure fuel pump. I am not confident the problem will be solved.

I was traveling at 40mph on August 14 when the engine stopped running suddenly and without warning. I lost all power. I tried pressing the gas pedal and the engine shuddered and sputtered with the speed ranging from 0 mph to about 18mph with no steady duration longer than a second or two. At the same time an engine icon appeared and a message displayed reading engine malfunction. I safely exited the travel lane despite having very little power. I waited 10 seconds and restarted the car and everything worked fine. I called the dealer explained the incident and to made arrangements to have the vehicle serviced. The appointment was for Friday. When I asked whether I should continue driving the car. I was told that so long as the engine icon was not flashing the car was ok to drive. The next day I started the car and did not see any warning message or engine icon. I thought all was ok so I cancelled the appointment. A second incident occurred later in the morning. I called the dealer again and was told to bring the car in that afternoon, Thursday. On the way over to drop off the car a third incident occurred with the same characteristics as the first two. Each time waiting 5 to 10 seconds restored power to the car. One week later the car was returned to me with the diagnosis of low fuel pump pressure problem. I am wary of driving this car on any trip especially on a speed highway for fear this situation will occur when I am driving at 70mph. I appreciate your taking the time to read this description of a very scary and unnerving situation that no one should face.
