Another Honda fuel pump recall announced for popular Honda and Acura models

Laguna Hills – June 6, 2020 – In the latest in a litany of 2020 Honda recalls, the automaker has recalled thousands of vehicles over a potentially-faulty fuel pump that could cause the cars to stall. But unlike the last recall, which only affected models with a certain V6 engine, this recall affects all the following models, regardless of engine:

  • 2018-19 Acura NSX
  • 2019 Acura RDX
  • 2019 Acura RLX
  • 2019 Acura RLX Hybrid
  • 2018-19 Honda Accord
  • 2018-19 Honda Civic
  • 2019 Honda Fit
  • 2018-19 Honda HR-V
  • 2019-20 Honda Insight

Honda says 136,057 vehicles in America are affected; worldwide, over 1.4 million vehicles are hit by this recall. Honda will notify owners of the affected cars of the recall by the end of July, but owners can find out if their car is affected right now.

Fuel pump failure

A manufacturing defect could cause the fuel pump in the affected models to suddenly stop working, depriving the engine of fuel, and causing it to stall. This stall could happen at any speed, and entirely without warning.

Stalling can cause a loss of control

Like other defects that could cause a car to stall at highway speed, a faulty fuel pump poses a grave safety risk: not only is it possible you won’t be able to accelerate, you could also lose power steering, power brakes, and other systems that make your car much easier to drive than it otherwise would be. If your fuel pump fails, you will not be able to restart the car.

The safest thing to do is turn on your flashers and try to get out of the road. If traffic conditions do not permit you to do this, stay in your lane – you don’t want to block two lanes at once. Call 911 and stay in your car until help arrives, because your car isn’t going anywhere without a tow.

While Honda and Acura recall reports show no known accidents because of this defect, the possibility of a crash remains.

Honda recall history

While this is the first 2020 Honda recalls for the affected cars, other recalls have revealed other Honda safety issues. Earlier in 2020, fuel pumps in other cars were recalled, while in 2019, over 100,000 2019 Honda CR-V’s were recalled for potentially-dangerous air bags.

Get it fixed for free

Once parts become available, Honda will repair all the affected vehicles for free at any certified Honda or Acura service center. Owners of these vehicles are encouraged to proactively look up their VIN to find out if their vehicle is part of this recall.

Honda recalls nearly half a million vehicles for fuel pump issues

Torrance, Calif. – February 20, 2019 – Honda (American Honda Motor Co.) is recalling certain:

  • 2016-2018 Acura MDX
  • 2015-2019 Acura TLX
  • 2015-2017 Honda Accord vehicles

These models were equipped with a 3.5L V6 engine. The recall is due to potential fuel pump issues, and 437,032 units were potentially affected.

The defect

According to the National Highway Traffic Safety Administration Safety Recall Report on this incident, sodium particulates contained in low-quality fuels can adhere to certain internal components in the fuel pump.

This can eventually lead to build-up, which in turn increases the electrical and mechanical resistance inside the pump, and subsequently reduces fuel pump performance.

If a vehicle is operated in surroundings with high ambient temperatures, a reduction in fuel pump performance can restrict vehicle acceleration, cause an engine stall or both. If the engine stalls while the vehicle is moving, the chances of a crash greatly increase.

Timeline of events

Honda received the first report of an engine stall prior to August 2017. Claims were minimal and infrequent, so Honda made the decision to continue monitoring the market.

Between August and September 2017, after additional engine stall reports, Honda launched an investigation. Failed return parts were sent to the fuel-pump supplier.

It was known that the fuel pump operating voltage could vary between 10 V-13 V. The supplier was able to recreate the engine stalling condition while operating the fuel pump in 10 V mode.

Between October and November 2017, sodium deposits were found on the brush and commutator components in the failed fuel pumps, and between December 2017 and June 2018 Honda conducted additional tests, determining that low-quality fuels were to blame for the problematic presence of sodium.

Recreation tests confirmed that fuel containing greater than one part per million of sodium could result in the aforementioned restriction in regard to safe vehicle acceleration, or potentially result in a stalled engine.

Between July and November 2018, more testing confirmed that when the fuel pump operated in 10 V mode, more sodium could accumulate within it.

This situation was found to result in increased mechanical and electrical resistance, and caused a reduction in fuel pump performance. Poor pump performance can lead to an engine stall as well as restricted or rough vehicle acceleration.

On January 22, 2019, Honda determined that a credible defect related to motor vehicle safety existed. The automaker then made the decision to conduct a safety recall, having received 731 warranty claims and 102 field reports but no accounts of any crashes, injuries or deaths directly related to this issue.

The solution

According to a media release from Honda, all owners of registered vehicles are being contacted by mail. The notice will request that each owner take their vehicle to an authorized Acura or Honda automobile dealer.

Once the car has been brought to the seller, the FI-ECU will be updated with software programming that disallows fuel pump operation in the 10 V range and thus prevents the potential for sodium accumulation.

If the vehicle owner informs the dealer that they have experienced an engine stall, and this is confirmable via a diagnostic scan, the fuel pump will also be replaced.

Both services will be completed at no cost to the owner. Additionally, any owners who previously paid to have one, or both repairs, completed out of their own pocket will be eligible for reimbursement. The recall is expected to begin March 25, 2019.
