Acura TLX 2017, with only 112,000 miles. On [XXX], while the consumer was driving, the vehicle caught on fire. The consumer saw what appeared to be smoke coming from under the hood. The consumer stopped the vehicle immediately at a 4-way intersection, put it in park, and turned it off. The hood latch was open. When the consumer opened the hood, the engine compartment was on fire, and the car was engulfed in fire within seconds. Fire department and Police depratment arrived at the scene. The car was deemed a total loss, and the fire was determined to have started in the engine compartment. In May 2024, Acura stated that the connecting rod bearing needed replacement and that it was covered under the recall. However, 6 months after replacement, in October 2024, the knocking noise returned. The vehicle was brought to the Acura dealership, which noted at that time that the engine needed to be replaced, but the repair was denied under the recall this time. As required and recommended by the Acura Dealership, as well as by the recall, which noted safety risks, the consumer moved forward with having the engine replaced by the Acura Dealership, and the cosnsumer paid out of pocket. The vehicle was at the Acura dealership in Westwood for service from October 2024 until February 2025. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Acura Service Bulletin B18-014 (NHTSA TSB #10135108) The repeated failure of the driver’s power seat height-adjustment mechanism due to stripped internal gears in the Vertical Transmission Assembly (VTA), as identified in Acura Service Bulletin B18-014, presents a significant safety concern. A…
Acura Service Bulletin B18-014 (NHTSA TSB #10135108) The repeated failure of the driver’s power seat height-adjustment mechanism due to stripped internal gears in the Vertical Transmission Assembly (VTA), as identified in Acura Service Bulletin B18-014, presents a significant safety concern. A failure of the driver’s seat adjustment mechanism can prevent the driver from maintaining a proper and secure seating position, potentially impairing visibility, access to the pedals and steering wheel, and the ability to safely control the vehicle. Because Honda/Acura has documented this failure and identified a specific repair procedure, I believe the defect warrants investigation by NHTSA and consideration for a safety recall rather than leaving affected owners responsible for repairs. Despite the Acura bulletin and recommended repairs, Marysville Honda in Ohio is recommending a $5700 repair bill inconsistent with the Acura bulletin.

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.

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.

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.

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.

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 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.

I was driving on the freeway and I heard something explode followed by a clanking noise. The oil light and battery light came on simultaneously and I could not accelerate. I immediately pulled over and noticed that all the oil drained out of the car. When I got a chance look under the vehicle there was a hole in the oil pan. A mechanic said that it had happened from the inside. Possibly something from the motor broke off and shot out of my oil pan.

The contact owns a 2017 Acura TLX. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling); however, the failure occurred five months after the recall repair. The contact stated that while driving at an undisclosed speed, the engine started knocking. The vehicle was taken to the dealer, who performed a valve adjustment, but the failure persisted. The manufacturer had an engineer inspect the vehicle at the dealer and discovered there was wrist pin play on piston #2. The contact was informed that the short block needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but refused to replace the short block due to aftermarket components on the vehicle. The failure mileage was approximately 94,000.

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.

[XXX] [XXX] > 4:28 PM (19 minutes ago) to takahiro_hachigo American Honda 1919 Torrance Blvd PO Box 2215 Torrance, CA 90509 - 9870 RE: Request for Financial Compensation Vehicle: 2017 Acura TLX VIN: [XXX] Dear American Honda Executive, I am reaching out as a long-term and loyal Honda customer, having owned multiple Honda vehicles over the past 30 years, including a 1990 Accord, a 2000 Accord, a 2005 Accord, a 2006 Odyssey, a 2011 Odyssey, a 2012 Accord, and most recently, a 2017 Acura TLX. Honda’s reputation for reliability has been a significant reason behind my continued support. However, recent mechanical issues and recalls, especially those affecting V6 engines, have left me with concerns. I purchased the 2017 Acura TLX in May 2023, unaware of any recalls or issues associated with this car’s make, model, and year. Just a month later, in June 2023, the vehicle’s engine caught fire while my son, a college student, was driving. Fortunately, he was able to walk away without injury, but this experience was alarming and has led to significant repair expenses. After the fire, I learned that there was a recall affecting Acura TLX models. I promptly filed a claim with Honda in November 2023, but the claim was denied without explanation, leaving me to cover the costs myself. With the National Highway Traffic Safety Administration now investigating similar engine failures, I feel that my concerns are not isolated. Given my longstanding loyalty to Honda, I respectfully request financial compensation for these repair costs or, alternatively, a credit toward a certified used or new vehicle. I am open to working with Honda to resolve this matter fairly and amicably. Thank you for your attention to this issue. I look forward to your response. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 NHTSA 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.

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.

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.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.

The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW. The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications. The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU. In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment. FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle. Other FCA vehicles that also used the subject ACU, but were not equipped with cross-car harnessing, had not experienced EOS failures, despite similar time in service. During the course of this investigation, ODI sent two separate Information Request (IR) letters to six vehicle manufactures (including FCA, Hyundai, Honda, Kia, Mitsubishi, and Toyota) and one IR letter to ZF-TRW. These IR letters resulted in ODI receiving comprehensive data from these manufacturers and suppliers. Studies of this data found that the DS84 ASIC does not have sufficient protection against negative electrical transients or electrical overstress (“EOS”) that can be generated in certain severe crashes. An electrical transient occurs when the electrical power supplied to a circuit changes momentarily over a short duration of time. In these severe crash cases, the crash sensors and other powered wiring can be damaged and short circuited so as to create a negative electrical transient of sufficient intensity and duration (that are outside the vehicle manufacturer's specification) to damage the ASIC before the restraint device deployment signal is received by the SRS ECU. This damaged signal can lead to incomplete or nondeployment of the air bags and/or pretensioners. Airbag non-deployment and/or lack of pretensioner operation can increase the risk or severity of injury in a crash.A total of 8 fatalities and 14 injuries were associated with known EOS events. The common element in all investigated manufacturers vehicles is the SRS ECU containing a DS84 ASIC manufactured by ZF-TRW. The risk associated with the ASIC is equally shared among all OEMS involved in the investigation. The actual real-world risk can be mitigated by other factors which were assessed by ODI during this investigation. The first mitigating factor involves protections built into the ACU design which protect the DS84 ASIC from damage. There are multiple strategies and levels of protection employed by different OEMs that provide effective EOS mitigation. The two most common strategies at the ACU level are circuit protection diodes on the remote senor signal lines, and current limiting resistors that protect critical components. The second mitigating factor is found at the vehicle level and involves the location and routing of the wires leading from the crash sensors to the SRS ECU. If the wires are well protected in a crash and are not routed with other power wires carrying large currents, the risk for an EOS event is significantly reduced or eliminated. These design specific factors combine to produce a spectrum of risk for the vehicles equipped with ACUs using the DS84 ASIC. Given the many of years of field exposure, it is possible to divide the subject population into two groups; vehicles which have experienced EOS events, and vehicles which have not experienced EOS field events. Four of the six OEMs involved in this investigation have experienced EOS field events on at least one of their models equipped with a DS84 ASIC. All vehicle models (including the Toyota models identified in the Failure Report Summary of the opening resume for this investigation) with field events have been recalled. In an abundance of caution, ODI kept this investigation open five years to monitor field performance and did not identify any field events on vehicles not included in existing safety recalls. Given the spectrum of risk identified in this investigation and that all vehicles with a demonstrated unreasonable risk have been recalled, ODI is closing this investigation. ODI is closing this investigation with the following manufacturer safety recalls: 16V-668, 18E-043, 18V-137, 18V-363, and 20V-024. With the recall actions taken by the subject vehicle and equipment manufacturers, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or model year vehicles outside of the recall scopes. The agency reserves the right to take further action if warranted by the circumstances.
