Advice To Mazda CX-5 Owners About To Deal With the Fuel Pump Recall
This week, Mazda owners learned that the vehicle they own may be subject to a fuel pump-related recall. This recall is similar in many ways to one that Toyota owners have been undergoing. Consumer Reports has reported, “(The) problem is due to a batch of over 2 million faulty low-pressure fuel pumps manufactured by Denso, an automotive supplier, which were installed on vehicles made by Acura, Ford, Honda, Lexus, Mazda, Mitsubishi, Subaru, and Toyota.” The Toyota recall reporting at this site has generated over 7 pages of comments from owners who experienced the recall. We have noticed some important trends among the owners based on this feedback.

Suggestion One - Document Your Average MPG Now
Many owners of Toyota vehicles who have had the fuel pump recall report significantly lower fuel economy after the repair. We are not talking about a reduction of 1 MPG, or a small difference. Rather, owners are reporting that in many cases the miles per gallon drop by 20 to 25%. One 2018 Camry owner and reader whose comment seems to typify this side effect reported, “My car is down 7 MPG and about 100 MPG to a tank. Had my pump replaced in late May. Have hesitation upon acceleration as well. Seems as if there is a disconnect from throttle to engine or the engine takes a large gasp of air before responding. RPMs jump ridiculously high. Car was perfect before replacement.” You can read the comments from Toyota owners under the story at this link.

By documenting your mileage with images and notes now, you will have more effective communication with your Mazda dealership in the event that something changes after the repair. In the gauge cluster behind the steering wheel is the average MPG. Do not reset your average MPG. You can use the “B” trip odometer to start a new average now and then document the mileage the vehicle has and the miles of that sample. We suggest owners do so. A significant drop in mileage is a common complaint from owners of Toyotas that had their fuel pumps replaced. We suggest that owners take images showing the average MPG reading in their vehicles.
Suggestion Two - Ask The Dealer If Your Car Will Smell Like Gasoline After the Repair
A small sampling of Toyota owners who had the fuel pumps replaced in their cars report that they can smell gasoline in the cabin. This is never acceptable. However, some also report push-back from dealers about it. We suggest that you ask the dealer to confirm prior to the work that the vehicle will not smell like gasoline after the repair is completed and that if the dealer says it might, stop and phone Mazda’s customer advocacy line for clarification.
Suggestion Three - Document or Correct Any Poor Performance Now
In advance of the recall being implemented, if your vehicle runs poorly you should advise your dealer now and make an appointment to have it investigated and corrected. All of the vehicles in the recall should still be under the five-year, 60,000-mile powertrain warranty. If your Mazda is under warranty and not performing properly, have it inspected now. It may be related, or may not be. In any case, some Toyota owners say things to the effect of “Car ran poorly before recall…” Never head into a recall without having reported performance issues and having given the dealer a chance to rectify those problems. It only amplifies the potential problems after the recall is completed.
Fear, uncertainty, and doubt is not part of the daily reporting this author does at Torque news or other outlets. However, with so much feedback from owners of Toyota vehicles flooding our stories in the comments section under coverage of this topic, it is only reasonable that we would provide this information to our readers who are Mazda owners.
