2017 Acura TLX: engine stalls while driving

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.

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.

There was a recall issued on Nov 2023. The manufacturer has informed me about this in Jan 2024. After that there is no update. In other words, its been 6 months and mfg still haven't fixed this. Based on what I read on the description of recall, this issue can be serious (Stall of engine) which is not safe and also can get expensive if it happens. So, I am raising this complaint hoping you will look in to this and make manufacturer act on this sooner.

I have been stopped by traffic or stop light when I put my foot on the gas to start up, the car stalls. The whole dashboard is lights up and I have to try several times to get engine started. This is very scary.... I took the car to dealership. After 4 hours at the dealership and $155, my car is stalling again. I am scared I could get hurt in this car!

Car stalled while in traffic line with Auto idle engaged. Took foot off brake to move forward and car stalled. Unable to restart car after the stall. Had to be towed to Honda dealership, they assessed it was an alternator issue. Alternator replaced car starts normally. Drove car for approximately 30 min and had turned off the Auto idle feature. Car stalled again after sitting in traffic and trying to move ahead. This time car restarted without issue. No warnings or messages on that I noticed. Have read many forums that describe similar issues to Honda and Acura's

I have a problem with the transmission not shifting down and up a gear when it should. This happens at speeds 5 MPH to 40 MPH with gears 1st through 5th. A great example is when I accelerate from rolling at 5 to MPH, press on the gas to speed up and it will not down shift from 4th or 5th gear to speed up, it stays in 4th or 5th gear at around 1200 rpms as it speeds up as to 40mph. Even if I have my foot to the floor it stays in that gear unless I use the paddle shifter to force it into a lower gear to speed up. I have had the car in acura service twice now for this and about to take it in a third time for this. It has on numerous occasions almost caused an accident. Imagine turning to off a highway, seeing oncoming vehicles and when you hit the gas to cross you expect it to accelerate but instead you get hesitation to the point that if it were any worse you'd think the car stalled. This is in normal mode, when it is in sport plus mode this issue is almost non-existent. I bought the v6 for the extra power but at times it seems as if its only a 2 cylinder engine. This is absolutely a safety risk and will eventually lead to an accident. This happens at least once a week and is more likely to happen within 10 minutes of starting the car. This still happens even after taking it in for the fuel pump recall from january 2019.
