2017 Acura TLX fuel system problems

Filed Jul 15, 2026 · Engine, Fuel system · TX

My 2017 Acura TLX stalled dangerously on the highway due to an unexpected fuel delivery failure, creating an immediate traffic hazard. Hiley Acura of Fort Worth diagnosed the vehicle with code P0087 (Low Fuel Rail Pressure) and confirmed it needs a new low-pressure fuel pump assembly for $1,540.62. They also pulled code P0430 (Catalyst System Efficiency) showing my front catalytic converter has failed, costing $2,461.77.The low-pressure fuel pump failure starved the engine of fuel, causing the highway stall. This fueling issue directly overheated and destroyed the catalytic converter substrate.This pump failure is the core subject of the Oliver v. Honda class action lawsuit. Honda previously issued a temporary corporate software update on my vehicle that deliberately altered how the computer reads errors, masking the physical fuel pump defect. This software update is the exact reason my car currently shows no open recalls on standard databases, despite still containing the defective, unreplaced factory hardware. This temporary software fix has now failed, resulting in a dangerous highway stall, and Honda is using the software-cleared VIN status to deny safety coverage.

I was refueling my vehicle at Fullerton Costco, the internal metal flap of the capless fuel filler neck is stuck closed and preventing me from inserting a gas nozzle to refuel the vehicle. I could not refuel my gas tank. Luckily, my vehicle still has some fuel left, enough for me to get to the nearest Acura dealer (Cerritos Acura) to have them fix it. It was expensive though for an issue that should not happen at all. Also, a vehicle cannot be refueled or has a failed fuel neck flap, it can become a safety hazard and this is the main reason I file this complaint against Acura.

My daughter was driving her car to work. Well in the middle of rush hour traffic the car put itself in neutral and then would not move and all of the lights were displayed on the dashboard as if the car was turned off. The car would not go into gear to move forward. She put the car in park and then shut the engine off. The engine shuttered and the car shook while it turned off. He then tried to start it and then started again and it started up okay and was able to put the car in drive and move forward. I spoke to my mechanic and he said that there is a recall on this car for fuel pump issues. I checked the VIN and it said that there was no open recall. However I wanted to report this incident to document it for this particular car because it could have a fuel pump issue.

On September 30, 2024 I received a notice from Acura titled “Important Safety Notice” (Recall Number 23V‑751). The recall concerns a manufacturing defect of the engine crankshaft. On October 1, 2024 I contacted Nalley Acura of Marietta, Georgia about scheduling an appointment and was told that the first available appointment was not until July 24, 2025 (almost ten months later). I was also told that the recall is not a safety concern and that I can continue to drive my car. I find it incredulous that Acura can issue a “safety recall” and then claim that the first opportunity to perform the repair is ten months later. Being forced to wait ten months to repair a manufacturing defect is outrageous and dangerous. Is this a subterfuge by the Company to avoid performing the repairs? In addition, I am confused by the dealerships response that this is not a safety concern. The recall notice states “due to a manufacturing defect of the engine crankshaft, the connecting rod bearing can prematurely wear and seize, causing engine damage. A damaged engine may run improperly or stall while driving, increasing the risk of a fire, crash, or injury”. Is the recall notice incorrect - that the matter under recall is not a safety concern? Additionally, I received a call from Honda Customer Service on Friday, October 4, 2024. Among other things, I was told that as part of the recall, I may be charged for a "diagnostic test" if the dealership looks at my car and finds a repair is not needed. Waiting ten months for a safety recall is unacceptable and I hope the federal safety agency investigates this further and forces Acura to explain how it can take so long to perform the service caused by its manufacturing defect. Also, to incur a charge as part of the recall process is unacceptable and will only discourage consumers from taking their car to a dealer.

Car experiences intermittent electrical system failure. Upon failure, drivers will experiance random and rapid clicking, clanking, and electrical systems discharging like lights, screens, and alarm. After restarting the car, users will find, all warning lights displayed with a few blinking: transmission, parking brake, traction control, a few more. Headlights will randomly turn on, as well as the alarm, intermittently. All ADAS offline. Experienced sudden system failure causing all ADAS to fail while stationary/parked or moving/(actively driving on highway). Does actively affect driving ability more specifically: disrupts steering ability, causes random malfunctions with electrical components, cannot exceed 40 mph, car will not shift above 3rd gear, engine does seem much louder. After a thorough investigation/diagnosis with the dealership I concluded the main fault is due to the "Smart Power Control Unit" located behind the glovebox compartment of the vehicle. More specifically, one of the chips on the circuit board is not fully coated with sealant from the factory, leading to a potential for some kind of mold, dust, or organic growth to form and short one of the ground pins on the end of the chip. Driver States: This is a control unit failure, I believe a small short on a single ground pin with the positively charged chip housing was causing a short within the control unit circuit board where the chip was not fully covered with non-conductive coating/sealant. This caused a handful of issues, like electrical systems prematurely wearing due to rapid discharge of electronics. Impairs drivers ability and ability in turning, braking, and accelerating. Also car will roll backwards if driver is not careful. BIGGEST CONCERNS: FIRE, partial loss of control while driving, and premature wear on electrical components. A extra note: Disconnecting battery does temporarily fix issue but rarely, most time it will start discharging electrical systems immediately or in the day.

My car’s lights were on. I went to Acura to get a diagnostic and they said to replace the fuel pump. I replaced it, and the lights came back on. I got another diagnostic and I was told the fuel pump has a leak. I have an 2017 Acura TLX that was not apart of the recent recall which I believe it should have been because my car is slow to steer which may cause an accident.

Acura TLX TECH showing "Check Engine", "Break" and Warning sign on the dashboard. Vehicle was taken to Acura Dealer at East Brunswick on 08/29/2022. They inspected the car and advised that the issue with "Pipe Kit, Fuel Filler Part #06160-TZ3-A11". The part was ordered by the dealer up on my request with a comment that part is back ordered and no firm expected time per Acura corporate and advised that I shall look for part from other dealers as well. I was advised that vehicle is drivable. As a fallback I ordered part from OEM Acura Parts on 08/30/2022 and got the same message from them as well that its back ordered. Upon several follow ups and calls still part is unavailable and car is not fixed. Dealer advised in April 2023 that I shall call Acura corporate to determine the expected arrival and I open a case with Acura Corporate with Case ID: 13772219 and had follow up call with customer services on 04/21/2023 and 4/28/2023. Finally got a call back from Case Manager Chris on 05/01/2023 and he said "No definitive ETA, Part not available. What best he can do is to send period update via email and call when part is available." I am in the state of New Jersey and vehicle inspections are mandatory, My car inspection is due soon and in case car is not fixed, then there is no way vehicle will pass inspection and I will be forced NOT to drive the car.

I bought my acura about 3 months ago but saw they had some recalls on over 400k of these vehicles with fuel issues! Is this going to be an issue for me later with this vehicle? Right now my vehicle is fine though, just wanted it to be known.

This started happening several months after purchasing the car. Between july through now, still does it off and on.
