There are 10 owner-reported fuel system complaints for the 2016 Mazda CX-5in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
High pressure fuel pump has been replaced twice in less than a year. Car has less than 100,000 miles. Both times the fuel pump went out while driving, causing loss of acceleration and stalling of vehicle. Had to be towed to shop both times.
The fuel pump system needed to be replaced completely, although the mileage is just around 60000 miles.
The contact owns a 2016 Mazda CX-5. The contact stated while driving at an undisclosed speed, the vehicle stalled and lost motive power. The contact stated she was able to drive the vehicle to a safe area before the vehicle lost motive power. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic, where it was diagnosed with an inoperable fuel pump. The contact was informed that the fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 66,000.
Denso Fuel Pump should be recalled!!! It is not sending fuel to the my engine properly it's running rough at even 0-30 miles, becomes difficult to start (cold or mild engine), sputters and idel, and suddenly stalled out in the middle of the road several times, put us in danger from other motorist. My check engine warning indicator is also on, it's not shifting correctly and is lacking rpm power. Mechanic put a code scanner on it and found P0192 (low fuel rail pressure) and P0171 (System too lean)... I have the pictures. Several auto makers have issued recalls, including Mazda. But Mazda only went back as far as 2018. Toyota recalled cars as far back as 2013. Mazda needs to do the right thing or be forced to do so!
Fuel system failure at only 60k miles on car. Engine light came on dash & my car just randomly started failing as if it wasn't getting gas, trying to cut off while driving down the road!! Huge hazard!! This could have caused an accident but i luckily going in a 25mph zone. Local shop diagnosed the fuel pumps failed (this car has 2 of them) and they also were able to reproduce the same issue when going to start the car to move in and out of the bay. I have called mazda and done the research- they did not put a recall on this year but it appears other years gave been recalled with fuel system related issues. This should be looked into as I've found NUMEROUS complaints on this year and model!
The low pressure fuel pump on my Cx-5 failed on my drive back home, while in a remote area. I was able to limp the vehicle home with a check engine light that illuminated (at the time of the incident) and erratic vehicle performance (uneven power deliver). This occurred on level ground at highway speed - no incident precipitated the part failure. Once home the following day, the vehicle would not restart. Upon diagnostic review, the vehicle had thrown two codes, one being a low fuel rail pressure (P0192 and P0171). This is a know issue for these defective (Denso) fuel pumps. The manufacturer should extend the recall to include vehicles manufactured prior to 2018.
My son was driving the car when it suddenly lost power and would not shift correctly. This occurred without warning while in moderately fast traffic that was moving at 40-50 mph. There were no warning lights illuminated prior to the problem occurring. Upon reviewing trouble codes, it is likely that the low pressure fuel pump located in the fuel tank has begun to fail. When the tank gets low on fuel, about 1/4 tank, the low pressure fuel pump is unable to supply enough fuel to the high pressure fuel pump. This results in sudden loss of power, and also hard starting. I believe the fuel pump is the problem because it was manufactured by Denso, who recalled 2,000,000 similar fuel pumps two years ago. Those pumps were recalled because they created the exact problem we experienced. Toyota recalled vehicles using these pumps as far back as 2013. However Mazda and other OEM's were allowed to only recall vehicles going back to 2018. EVEN THOUGH IT IS THE SAME PUMP. When the manufacturing defect that causes a safety problem is well known, why are some manufacturers allowed to limit their recall? Why aren't all cars using the pump forced to be recalled? If a recall is excessive, why aren't manufacturers required to provide an extended warranty? NHTSA, you dropped the ball on this, and you need to fix it.
