2017 Acura TLX Complaints

ENGINE,FUEL/PROPULSION SYSTEM — Filed 07/04/2026

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.

STEERING,SUSPENSION — Filed 06/01/2023

Vehicle consistently pulls to right and on grooved concrete acts in abnormal way, weaving withing the lane. I have taken to Acura to try to diagnose - they tell me there is no adjustment they can make. I have tried with Honda corporate, but they want me to go back for another diagnosis on the car at Acura. At this time there is no reason to duplicate efforts or time. I have also taken to independent shops and they indicate they cannot correct the problem also.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER — Filed 07/14/2025

The keyless access unit broke around 100k miles. Car acted like it was having a seizure. If car was locked, alarm goes off nonstop (during these episodes, which are intermittent) and all dash lights and head lights blink on and off over and over in quick succession. If car was not locked, only the lights had a seizure, there would be no audible alarm. Seemed to happen more near towers (cell towers, fire station broadcast tower, absolutely could not leave the car alone in nyc and had to go home). So so so embarrassing. So many people with this issue.

My car broke down on 04/05/2026 on the highway at a light with on coming traffic.I took it to express oil change 04/06/2026 they told me my car need a crankshaft so I proceeded to get more information and come to find out it was a recall on the crankshafts on my car. This is the second recall I have had done to my car the first recall was for the motor. This second one is for the crankshaft recall number- CH7. I was told by Acura a month and a half after them having my car that the serial number on my motor doesn’t fall up under the recall, but my vin number does and there saying they can not fix my car. Only had this motor for 2 or 3 years from the first recall it had on it.

FUEL/PROPULSION SYSTEM — Filed 04/09/2026

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.

ENGINE AND ENGINE COOLING — Filed 04/02/2026

The contact owns a 2017 Acura TLX. The contact stated the vehicle was repaired under NHTSA Campaign Number: 23V751000 (ENGINE AND ENGINE COOLING) but the fix failed to repair the vehicle. The contact stated that after the repair was performed, there was an abnormal fuel odor coming from the vehicle. The vehicle was taken to the dealer approximately five times to be diagnosed, and it was determined that the oil rings on the fuel injector had detached. The oil rings were replaced, and the vehicle was repaired. The manufacturer was notified of the failure, and the contact was referred to the NHTSA Hotline to report the failure. The failure mileage was 142,000.

UNKNOWN OR OTHER,SERVICE BRAKES,ENGINE — Filed 02/24/2026

My 2017 Acura was involved in a low-speed collision where it failed to stop in a timely manner, resulting in a total loss declaration. This vehicle had open safety recalls (including the fuel pump/rod bearing issues) that remained unrepaired for over 1.5 years. Despite multiple inquiries, the manufacturer failed to provide a repair timeline or remedy. I believe these unresolved defects directly contributed to the braking failure and subsequent safety incident.

UNKNOWN OR OTHER — Filed 09/29/2025

My car shuts off at idle without warning. No lights or codes. I’ve seen a fuel pump issue is the cause on other models like mine.
