2016 Acura MDX: fuel pump failure

Filed Jan 30, 2026 · Fuel system · MA

Hi, Vehicle experienced sudden loss of power and inability to accelerate while driving. Engine entered limp mode and would not rev beyond approximately 2,000 RPM. Vehicle became unsafe to operate in traffic due to lack of acceleration. Dealer diagnosed fault code P0087 (fuel rail/system pressure too low) and confirmed failure of the high-pressure fuel pump. Vehicle had hard starting, delayed throttle response, and multiple warning lights related to engine, emissions, and drivetrain systems. This appears to be a fuel system failure affecting vehicle safety. Acura previously issued fuel-system-related recall(s) for similar vehicles, and this failure occurred despite prior recall-related service. Repair cost is approximately $2,400. Failure resulted in loss of engine power and posed a safety risk, especially when attempting to merge or accelerate in traffic. Vehicle mileage is approximately 160,000 miles.

My vehicle is showing the exact same symptoms that the 2016-2018 MDX fuel pump recall is stating but my VIN number is not part of the vehicles being recalled. I reached out to Acura relations and unfortunately, they cannot provide authorization to repair my fuel pump even though my vehicle falls under the same years that this model is being recalled for. I went to an independent shop to try and understand what the problem with my vehicle is and I was told that the high pressure fuel pump seems to be failing and was asked why I have not taken the vehicle to the dealership for the fuel pump recall. Due to this issue I am unable to properly use my vehicle. If i step on the accelerator too hard, the vehicle gets engine misfires and immediately goes on limp mode.

Acura has an open recall that shows the symptoms or malfunctions my vehicle is having for my year, make, and model, but the vehicle I.D number doesn't show this type of recall for it. Now, these things do not add up give the malfunctions I'm experiencing. First and foremost, the car stalls, I could be on the NJ turnpike and as soon as traffic slows down car goes into neutral on its own and engine just shuts off in the middle of traffic, do not know when its going to happen, it just happens. Car then turns on once fully stopped and foot is on break but probably after another hour same thing and it is continuous. I have replaced a number of things and it is still malfunctioning. the federal safety agency Recall # 19V‑060. No check engine light recorded since i bought the car and when running, car runs smoothly. It is preowned vehicle, called Acura and I was told that the fuel pump was replaced, but according to the recall it also needs a software update to fix the malfunction. At this point I just need help on taking the proper steps on getting this safety issue fixed.

My 2016 mdx has a fuel pump failure which has caused my mdx to stall and LED to problems with my fuel injectors. There is a recall but my acura dealer refuses to honor it. On 10/18 my wife was driving the car on the free way and it slowed to a stall. This is a known issue. I have pasted a url to the recall below. The dealer refused to fix my fuel injectors or replace my fuel pump. The are offering a free fuel pump software upgraded but they want me to pay to replace the fuel pump and fuel injectors.

2016-2018: noticed car occasionally hesitant like not 'getting' into gear but no stalling. Wife driving car and stalls while stopped at a light. Simply restarts car with no issue. February 2019: wife driving car and stalls but when restarted, all lights in dash are on and car will only move forward at idle speed and throttle completely not responsive (e.g., can press gas pedal to floor with no acceleration). Regal acura (2615 lakeland hills blvd bldg 2, lakeland, fl 33805, (863) 262-4238)) visit 1 (march 2019): matthew in service. Regal service does full check and reports 'nothing wrong.' march 2019: vehicle continues with hesitancy and stalls. Regal acura visit 2 (march 2019): bring back to matthew and they repeat check and finding nothing wrong. I insist on fuel line flush which I pay for. April 2019: vehicle continues with hesitancy and stalls. I call matthew in regal acura service and let him know that there is a recall (p3w mdx) on this issue. Regal acura performs software update. Vehicle continues to exhibit hesitancy while driving. April 2019: I receive letter from acura automobile division outlining the recall: 1.safety consequence per recall: 'reduced fuel flow to the engine combined with vehicle operation in high temperature conditions can restrict vehicle acceleration and/or cause an engine stall, which increases risk of crash.' 2.what will acura do? 'the dealer will update the software for the engine control unit'. If the diagnostic scan confirms a previous occurrence of engine stalling, the fuel pump will be replaced for free.' I have had multiple calls with regal acura and acura national and they will not replace fuel pump nor will they let me purchase a new fuel pump because there are none available due to the recall!!! I feel this car is unsafe to drive with current fuel pump as outlined in the attached recall letter.

Vehicle making high-pitch chirp after engine is warm. Noticable at idle. Not noticable during driving/cruising speeds. Took vehicle to dealer regarding high-pressure fuel pump tsb. Dealer stated that high-pressure fuel pump was not involved. Stated it may be due to the starter (defective solenoid or drive piston not disengaging). No current tsb exists for starters. Please investigate.

Nothing but trouble since I bought it. Purchased jan 2016. Has replaced --- navigation, amplifier & fuel pump!!! Owned 2016 mdx for less than a week- vehicle jolts forward-gives itself extra gas even when your foot is on the brake! Transmission not smooth. Been in for service over 40 days now (total). Hesitates sometimes- was stuck at 15 MPH for a few minutes. Radio goes unresponsive- no buttons work gets stuck at station/vol can't turn off either. Navigation died- turned off, then flickered(was replaced) . Speakers went flat- amplifier died (was replaced). The engine idle feature doesn't work right. It doesn't keep my samsung phone charged. I've tried multiple cords including the original one that came with phone. Acuralink doesn't always work either. I sent a destination but it doesn't show up for a few hours or days! It tweets now. The window now squeaks (no, it is not tinted or anything). It makes a strange dripping noise when you turn it off. It eats gas! I fill it up and it's gone in a blink..not the appropriate miles. It beeps loudly and blinks that there is an object approaching for no reason- no one/thing there- nothing moving. It has a mind of it's own. I've been a loyal honda/acura owner for over 18 years and they have not helped. When they replaced the navi they said they'd give me $500 for my trouble- but didn't anyway. They say there is nothing wrong with it-- but just monday said it needs a new fuel pump but is "so new" they don't have one so it had to be ordered. Disgraceful. I asked for it to be replaced- was denied. Acura client rep says- "at this time there is nothing we can do" I have a spinal condition and the jolting hurts me greatly. Somedays I can't drive my brand new vehicle bc I cant take the pain. They don't care. They don't stand behind their product either. Highly disappointed in vehicle and company

There is no way to place the car in neutral without turning the engine on. Today I was at a gas station when a fuel pump malfunctioned and there was a fuel spill that needed to be cleaned. The procedure was to move the car without turning on the engine so they can access the area to clean up the spill. After speaking to my local dealer and to the main contact phone number for honda north america, there is no way to get the car in neutral without the engine being on. This caused a significant delay in getting my car moved since a tow truck with a dolly was needed.
