2017 Acura TLX Problems

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 have this car 2017 acura tlx v6 shawd from acura dealership 3months already. I hear little knocking sound from my bottom block.

Vehicle has been recalled for a speed sensor issue that still persists. Recall repair was NOT properly executed. Vehicle engine still randomly shuts off while in idle at stoplights and during travel. Engine won’t start at this point.

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.

The contact owns a 2017 Acura TLX. The contact received notification of NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that the vehicle failed to start intermittently. The contact stated that while driving at various speeds, the vehicle failed to accelerate as needed. The contact stated that while driving at approximately 65 - 70 MPH, the vehicle began to decelerate with several unknown warning lights illuminated. The failure lasted less than a minute before self-correcting, and the vehicle was driven without failure. The failure had occurred several times while driving at various highway speeds. The dealer was contacted. The dealer informed the contact that parts were not available and would not be available until 2025. The manufacturer was made aware of the issue and stated that while speaking to the dealer, the contact was informed that vehicles that were experiencing failure were being repaired. The approximate failure mileage was 10,000. Parts distribution disconnect.

On May 11, 2024, while driving my 2017 Acura TLX on a local city street, multiple dashboard lights suddenly came on. Since that time these lights began to come back on more frequent and often will go into a Limp Mode. I have had the vehicle inspected at my local Acura dealership only to be told that the vehicles rear PAWS Actuators and Control Unit need to be replaced at a cost of around $8,000. They also informed me that a recall for this issue was only for the 2015 TLX and RLX models but there could be a recall for my model year at some future date. I find this to be unacceptable as I have found out there are multiple instances of this same issue happening with many other Acura owners.

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.

Emissions system problem/electric parking brake problem

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.

Vehicle has been recalled for a speed sensor issue that still persists. Recall repair was NOT properly executed. Vehicle engine still randomly shuts off while in idle at stoplights and during travel. Engine won’t start at this point.

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.
