Time for some interesting Acura repair news: In early 2019, Honda Motors issued a recall for various Acura models for fuel pump problems. The recall included Acura MDX and TLX models as well as some of the higher-end Honda Accord vehicles powered by the 3.5-liter V6 engine that normally purrs like a bobcat. A year later, that fuel pump issue has turned into a class-action lawsuit.
Imagine that you are driving through North Raleigh in your Acura MDX sports utility vehicle when you suddenly experience a deceleration that cannot be controlled; we are talking about a situation that could slow your car down almost to a stop. This is commonly referred to as loss of power or engine stall, and it can be dangerous if it happens on the interstate as you are trying to change lanes; that is what happened to a woman in Florida while driving her leased MDX on the highway, and she has now filed a civil complaint that could go national.
Understanding How A Faulty Fuel Pump Can Stall Your Car
Reading through the court documents in the aforementioned lawsuit, the plaintiff explains that the loss of power did not seem to impact the electronics or the air conditioning; when this happens, chances are that the fuel pump is failing, but there are various factors to consider.
If you feel that the engine sputters before it starts losing power, there may be a problem with the stream of fuel being delivered from the tank to the engine. The reason this often happens on the highway is because this is where you normally drive at higher speeds, and there is a need for increased fuel pressure.
While the initial filings of this lawsuit do not indicate whether the plaintiff took her SUV to an Acura repair shop, it should be noted that the 2019 recall by Honda Motors was highly technical; it addressed issues related to sodium particulates, which can be found in many automotive fuels, and which can clog some of the precise and tiny components of modern fuel pumps.
This problem is more likely to happen in warmer climates and when vehicles are traveling at higher speeds, which would explain why the main plaintiffs are Florida drivers. It would not be unreasonable to think that this issue could occur to Acura SUV owners driving down I-440 in the midst of a hot Raleigh summer.
In some cases, the first fuel pump component to fail would be its motor, and this is more likely to happen when external temperatures are higher. Fuel pumps are tasked with regulating fuel pressure, and they may cause the vehicle to lose power under stress because the right amount and mixture of gasoline is not being achieved.
The definitive sign of a fuel pump that no longer works would be noticed when the car no longer starts. If you get a solid crank when turning the key but the engine does not come alive, it is very possible that the pump is no longer delivering fuel.
Known Acura Repair Issues
The Acura fuel pump recall was coded as PW3 for Acura SUV owners and N3X for Honda Accord owners. The Acura TLX models are from 2015 to 2017 while the MDX models are from 2016 to 2018. The Honda Accord models are from 2015 to 2017, but only for cars equipped with 3.5-liter engines.
If you own one of these vehicles but have not received the recall notice, check with your dealer or contact Honda Motors North America.
At the heart of the recall was an issue with the engine control unit, which means that a software update could take care of it; in some cases, however, the glitch may have caused the fuel pump to become damaged, which would require replacement.
New Acura SUV models released after 2018 do not have this issue because the software was modified for improved interaction with modern fuel pumps that operate at lower voltage settings.
The majority of Acura SUV owners in Raleigh will find that their vehicles are reliable. Some of the most commonly reported Acura repair issues correspond to the MDX models from 2001 to 2004, which were equipped with a transmission that should have lasted longer than what we should expect from a Honda Motors product.
When the fancier Acura TLX was released in 2015, there were some problems related to rough shifting.
For the most part, Acura is a brand that can be trusted, but we are still talking about cars; should your Acura vehicle give you headaches, bring it to our shop so we can figure out how to improve your driving experience.
