Advice to Mazda CX-5 owners about handling the fuel pump recall

Mazda owners learned this week that their vehicle may be subject to a fuel pump recall. This recall is similar in many ways to the one that Toyota owners were subject to. Consumer Reports reported, “(The problem) is caused by a batch of more than two million malfunctioning low-pressure fuel pumps manufactured by Denso, an automobile supplier, and which are installed on vehicles made by Acura, Ford, Honda, Lexus, Mazda, Mitsubishi, Subaru, and Toyota.” The Toyota recall reports on this site have generated over 7 pages of feedback from owners who have tested the recall process. We’ve noticed some significant trends among owners based on these comments.

Suggestion one – document your average mileage per gallon now
Many Toyota owners who have the fuel pump report a significant reduction in fuel consumption after repair. We’re not talking about a 1 mpg reduction, or a small difference. Instead, owners report that in many cases, the miles per gallon drop by 20 to 25%. A 2018 Camry owner and reader has been reported whose comment appears to be this side effect, “My car is under 7 mpg and about 100 mpg for a tank. The pump was replaced in late May. You have hesitation in accelerating too. It looks as if there is a disconnection from the throttle to the engine or the engine is taking a huge gasp of air before responding. RPMs jump ridiculously. The car was perfect before the replacement.” You can read reviews from Toyota car owners under the story at this link.

By documenting your mileage with photos and notes now, you’ll have a more effective communication with your Mazda dealer if something changes after a repair. In the dashboard behind the steering wheel there is an average mpg. Do not reset your average mpg. You can use the trip odometer “B” to start a new average now and then document the miles the car and the miles traveled by that sample. We suggest owners do this. Significant mileage drops are a common complaint of Toyota owners who have had their fuel pumps replaced. We suggest owners take photos showing the average MPG reading in their vehicles.

Suggestion Two – Ask the dealer if your car smells like gasoline after repair
A small sample of Toyota owners who replaced the fuel pumps in their cars reported that they could smell gasoline in the cabin. This is totally unacceptable. However, some have also reported a response from merchants on the matter. We suggest that you ask the dealer for confirmation before work that the vehicle will not smell like gasoline after the repair is complete and that if the dealer says they might, stop and call the Mazda Customer Call Line for clarification.

Suggestion Three – Document or correct any poor performance now
Before carrying out the recall, if your vehicle is running poorly, you should inform your dealer now and make an appointment to have it checked and corrected. All vehicles in the recall must remain subject to a five-year, 60,000-mile powertrain warranty. If your Mazda is under warranty and not working properly, have it checked now. It may be related, or it may not be. Anyway, some Toyota owners are saying things that will “The car was going badly before the call…” Never head to the recall without reporting performance issues and giving the dealer a chance to correct those issues. It only amplifies potential problems after the recall is complete.

Fear, uncertainty and doubt are not part of this author’s daily reporting on Torque News or other outlets. However, with so many comments from Toyota owners flooding our stories in the comments section under this topic’s coverage, it is only reasonable to make this information available to our Mazda-owned readers.
