Mazda CX-5 fuel smell problems

Filed Oct 7, 2026 · Fuel system · NY

My car started to smell like gas. I brought it to a shop and there was a leak in my high pressure pump in which the gas was leaking on to my engine. I paid $1600 to have this replaced and there is only 88,000 miles on the car.

On May 11th I was driving my 2019 Mazda CX-5 with approximately 35,000 miles when my cabin filled with the smell of gasoline. The smell became overwhelming within minutes, causing concern for my safety and the safety of other drivers. I immediately drove to the closest auto repair/body shop for an emergency inspection. Upon inspection, the technicians discovered there was a "crack at rear cylinder head and leaking oil excessively. Oil is leaking on to hot exhaust manifold....car is not safe to drive since oil leak is excessive". I was advised that this must be a manufacturer defect as you should not see this issue at such low mileage. The vehicle was then towed to the nearest Mazda dealership/service center, where a cracked rear cylinder head was diagnosed and confirmed. I was informed that continued operation of the vehicle could have resulted in catastrophic engine failure, engine seizure, fire risk from leaking oil contacting hot engine components, or sudden loss of power while driving, creating an extremely dangerous driving situation. Prior to the failure, there were no major warning indicators other than the sudden strong fuel/oil smell. The issue occurred unexpectedly despite the vehicle being properly maintained and having low mileage for a major engine failure. I have been the sole owner. The vehicle is currently available for inspection upon request.

The car has signs of current recall in other Cx-5 Models. Hesitation with acceleration or driving at high speed, reduced power, not responding appropriately when accelerating or would accelerate on its own, strong smell of gas after the car has been driven and is parked. I know there is currently a recall for a gas pump failure. There is no engine light on.

The radio changes stations by itself, speakers/music goes in and out. The screen freezes and cannot change stations. And also the car lags on taking off sometimes. Often smells like fuel when you turn on the car, Assuming a fuel pump issue, not sure. I spoke to the salesman who sold me the car (adam) within less than 30 days of having the vehicle and told me the electrical issue with radio would be covered. Then when I called to have the issue fixed I was told it wasnt going to fixed on their behalf. This car was sold to me with a few issue that I was not aware at the time of purchase.

There is a pressure crack that goes almost all the way across my front windshield, there are no chips or dings in the glass. Second you can smell gas fumes near the back of the car but no gas is leaking

Had the sudden onset of strong exhaust fumes in the cabin as others have described - especially when idling at a light. Returned to dealer after having it up on a rack to find oil dripping everywhere (shield underneath prevents from seeing drops when parked) - got word today it is indeed the cylinder head assembly. How is oil running on hot exhaust not a fire concern? I had to roll my windows down for fresh air in zero degree weather the fumes were so strong inside the vehicle. On top of that the P0126 (thermostat stuck open) diagnostic code is back for the second year in a row after having the “fix” installed under warranty last year.

The contact owns a 2015 Mazda CX-5. The contact stated that there was an abnormal fuel odor inside the cabin of the vehicle. The contact stated that fuel was leaking from the vehicle causing the vehicle to need refueling more often. The contact stated the vehicle was previously repaired under the federal safety agency Campaign Number: 16V064000 (Fuel System, Gasoline) which required that the fuel pump or tank to be replaced. The contact took the vehicle to a certified mechanic who informed her that the repair only required a sealant and cover that had since corroded. The certified mechanic replaced the electric intake fuel pump assembly. The manufacturer was not made aware of the failure. The approximate failure mileage was 74,000.

Strong gasoline odor outside the vehicle. I verified that the gas cap is locked after filling up. I see no dash board warning lights that would suggest that there is a problem with the fuel cap or fuel system. The odor is still there even after running the tank down considerably. The smell is mostly detected on the driver side of the vehicle starting at the driver door and moving toward the rear of the vehicle where the fuel door is positioned. The smell is there in warm and cooler weather. It is 60 degrees F and I can smell .it.

Approximately april 2014, I began to notice a gas odor in the cab of my 2014 mazda cx-5 touring. The odor was stronger when I exited the vehicle and stronger still at the rear of the vehicle. It continued sporadically and began to grow in intensity over time. I then began to notice that my gas mileage indicator would drop the miles left on my gas tank from approximately 15-50 miles from the time it was parked to the next time I started the engine. On one occasion my vehicle lost all the gas and I had to call ins co for gas tow in july, 2014. I was also noticing dead spots on the grass section of my driveway under where my car had been parked. I scheduled an online appointment to mazda dealership where I had purchased the vehicle. I shared the aforementioned with serv advisor. He did not ask to see them. After insp, advisor stated he had not found the source of the gas leak but could smell the gas leak/odor from the vehicle and he arranged for a rental until they could identify the problem. The next day he still hadn't found the problem but mazda told him to replace the gas sensor. I asked him several times where the gas was leaking from and he stated he did not know. I expressed my concerns that if they didn't know, then how could they repair the leak correctly and safely. He stated he did not know where it was leaking from but would replace the sensor per mazda instruction and my vehicle would be ready on 8/14/14. I called advisor back on 8/13/14 to voice my concerns again but he never returned my call. This problem continues and is intermittent. I have recently contacted mazda corporate, 8/2016, and sent the pics to mazda corporate.
