There are 3 owner-reported fuel system complaints for the 2017 Mazda CX-9in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
This is the second time my car mazda -2017 had problem with fuel pump. I only saw recall for 2019 Mazda CX-9 in internet. Before the fuel pump fail, I smelled gas inside the car which I was told my mechanic later from the shop where I bought my car for immediate diagnose was considered dangerous. The first time happened 2 years ago when we were on the trip 250 miles from where we live. This time we were about 200 miles away. So the fuel pump it seemed became the problem for Mazda. When we asked Mazda about it they said it is not the same with recall for 2019. If those car has the problem with fuel pump and got the recall why Mazda 2017 did not get recalled? They said it is wear and tear but it is the same issue fuel pump. we spend $912 for original part and bought it from Mazda dealer but we couldn’t get reimbursed because they said it is not a recall. I am filing this complaint because they denied the problem with Mazda is actually and consistently fuel pump!. I have kids that I have to bring to school. Smelling gas, the car stop suddenly and lost power will get us into accident. So I am writing this to let you all know that 2017 Mazda has the same problem with 2019 Mazda which is fuel pump. Please take this seriously. Thank you
While driving in normal, operating conditions, the engine cut off and had to pull off to the side of the road. After checking the OBD two error code from the check engine light, there was an error with the fuel pressure rail sensor. Apparently the fuel pump in these vehicles has been failing with regularity on many other models.
Driving Eastbound on I470 Wheeling WVA going uphill toward Exit 10 Cabela Rd the car lost power and could not get off the roadway. The engine failed and the car lost power steering. Could not start the car. The car would turn over, but the engine and battery light were on. The car was sideways in the right lane of traffic unable to be started. State Patrol was called to the area and the vehicle was towed to a Mazda dealer. Mazda dealer determined that the PCM (powertrain control module (PCM) has detected a malfunction in the fuel pump control module) - they noted: "Found code p064a and in TSB 01-010/17 states that PCM needs to be reprogrammed if no other fuel pump codes are detected, no other fuel pump codes were found." Their explanation was that after driving for a long period of time that the computer no longer allowed fuel to the engine. Their actions to correct - "Comments from Service department: We reprogrammed the PCM and cleared codes, test drove and rescanned for codes and found none." This was a known problem by Mazda and they had issued a service bulleting TSB 01-010/17. The bulletin was issued PRIOR to us purchasing the car but the update had not been done on our vehicle, nor had it been done by any Mazda dealer we had taken the car into for service over the past 4 years. This issue that was known by Mazda created a safety issue by shutting off the fuel pump. We were driving at 70 mph on the interstate and could have been hit or worse yet killed. Mazda should have to recall these vehicles and pay for expenses incurred by owners. Mazda will not reimburse us for our expenses. We have contacted them.
