I am formally requesting a neutral third-party arbitration review under the Magnuson-Moss Warranty Act to compel American Honda Motor Co. to provide a permanent mechanical remedy—specifically, the sourcing and installation of a brand-new, redesigned engine assembly (Engine #Four)— This vehicle frame is now on its third engine block. Car was bought 11/30/2024. At Grubbs Acura, fuel pump safety recall that involves flashing/re-calibrating the Engine Control Unit (FI-ECU) software was done. Just a few weeks after new fuel pump, the vehicle displayed sudden stalling symptoms. The engine suffered a terminal, catastrophic internal collapse. The vehicle was towed to Grubbs Acura where Corporate Honda directed a forced out-of-pocket internal engine teardown. The physical teardown explicitly confirmed a catastrophic connecting rod bearing failure (spun bearing) identical to the structural manufacturing flaws currently under active federal investigation by the federal safety agency under Preliminary Evaluation PE25008 / RQ24-025. Corporate Honda subsequently issued a verbal agreement to fully reimburse my out-of-pocket teardown fees. Because a manufacturer will never fund diagnostic labor if evidence of owner fault is present, this corporate reimbursement serves as formal validation that no owner maintenance neglect occurred, and that the engine died exclusively from an inherent component defect. Gunn Acura (San Antonio, TX) confirmed with my vin, that Engine #3 was a warranty/dealer-installed replacement unit at 22,000 miles. It failed after less than 40,000 miles of total operation. A professionally manufactured and dealer-installed engine is reasonably expected to last well beyond 40,000 miles. The manufacturer network cannot utilize arbitrary part-ownership rules or uncooperative, fragmented dealer communications. The original factory-installed engine and the dealer-installed replacement engine both suffered identical connecting rod bearing failures.

I am filing a formal safety complaint regarding the execution of the federal safety agency Recall 24-002 (Connecting Rod Bearing Replacement) by an authorized Acura dealership, and a fundamental safety flaw in Acura’s official Service Bulletin for this recall. My vehicle underwent "Repair #1" under this recall, which involved opening the engine block and replacing the rod bearings due to a factory defect that causes metal-on-metal wear. However, upon picking up my vehicle, I discovered the dealership left the old, dirty oil filter attached to the engine. I reviewed Acura’s Service Bulletin 24-002 and realized the "Required Materials" list explicitly omits a new oil filter for Repair #1. Because dealerships strictly follow this bulletin for warranty reimbursement, they are systematically leaving old filters on engines that just received new bearings. This means old, metal-contaminated oil trapped in the filter is immediately recirculated through the brand-new precision bearings. This procedural flaw directly jeopardizes the integrity of the engine, completely undermining the purpose of the safety recall and putting drivers at risk of sudden engine failure at highway speeds. I have time-stamped video and photographic evidence of my vehicle’s mileage (61,325) and the untouched, original oil filter immediately after returning home from the dealership. Acura Corporate was contacted regarding this procedural negligence and failed to provide a resolution. I am requesting the federal safety agency investigate Acura's repair procedures for Recall 24-002 to prevent further unsafe vehicle modifications.

My engine has been replaced under warranty for connecting rod bearings failing before the recall 23V‑751 existed. 40,000 miles later it failed again. I have paper work and other information available upon request. The vehicle is currently on it's third short block replaced by Acura. No CEL or anything prior to when the knocking started.

In 2022, my 2019 Acura TLX A-Spec received a warranty engine replacement due to a spun bearing. At that time, recall 23V‑751 (connecting rod bearing defect) did not yet exist. Recently, the replacement engine developed a pronounced knocking/ticking noise at idle and during light acceleration. Multiple independent mechanics and an Acura service department confirmed the noise is abnormal and consistent with connecting rod bearing wear as described in the recall. Acura advised that my VIN is not included in the recall because the original engine was replaced. However, the replacement engine was supplied by Acura prior to the recall and may contain the same defective components. The dealership and Acura corporate did not inspect the internal components or verify whether the replacement engine used the revised bearing parts — they only referenced the VIN and engine number to deny recall eligibility. I currently have an open case with Acura, and the vehicle is scheduled for diagnostic inspection. I was informed that if the issue is determined to be related to recall 23V‑751, diagnostic costs may be reimbursed, but there is no guarantee. This situation raises concern because my symptoms, timeline, and component failure are consistent with the known defect, yet my vehicle remains excluded from coverage. Given the safety implications of possible engine seizure or loss of power while driving, I am requesting that the federal safety agency review whether vehicles with Acura-supplied replacement engines should also fall under recall 23V‑751. All service records and warranty history with Acura are available for review upon request.

My vehicle had an engine rod bearing issue before the 1st recall, they replaced part of the engine. My vehicle also went through a starter recall and they also changed the rod bearing with the corrected part that was in for the last recall. Currently, my engine is still having the exact same rod bearing issue which is a safety concern for me. It’s currently at Ed Voyles Acura in Chamblee, GA waiting on a decision from corporate Acura. They will determine if they will pay for the repairs of my vehicle due to an old recall. This is the worse experience I have had with the Acura brand and I have had 3 Acuras in my life time. I think Acura is a beautiful car company with great performance. I would love if this situation would allow me a rental until my vehicle is fixed. Thank you.

I am writing to formally request assistance with a premature engine failure on my 2019 Acura TLX A-Spec 3.5L (VIN: [XXX] , Mileage: 95k I have consistently followed Acura’s recommended maintenance schedule, as documented by my service history. My vehicle was also serviced under [insert recall number if you have it] at [insert dealer name], as required by Acura, and I have attached records confirming that the recall work was performed. Despite this compliance with all required maintenance and recall service, my vehicle has experienced a serious engine malfunction. This failure appears to be related to the same type of connecting rod bearing or crankshaft issue currently under investigation by the federal safety agency (the federal safety agency Preliminary Evaluation PE25008), which covers the 2018–2020 Acura TLX with the 3.5L V6 engine. Given that: •I have properly maintained the vehicle as recommended. •The recall repair was performed, yet the engine failure still occurred. •the federal safety agency is investigating this exact issue as a potential defect affecting safety and reliability. I am respectfully requesting goodwill coverage for the full cost of the necessary engine repair or replacement. If Acura is unable to offer immediate coverage, I request that this case remain open and that I be considered for reimbursement should a recall or service campaign be issued as a result of the ongoing the federal safety agency investigation. I chose Acura for its reputation for reliability, and I trust that Acura will stand by its customers when a serious issue like this occurs. I look forward to your timely response so we can resolve this matter promptly. Thank you for your attention and assistance. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This car suffers from the engine and rod bearing recall. I took the car to Park Avenue Acura to complete the recall work. The car had significant damage from the rod bearing issue and the dealership had the car for a month. They replaced the rod bearing, crank shaft, regular fuel pump among other things. Once I received the car, the car failed and became inoperable. This time the high pressure fuel pump became defective. While Acura representative informed me that there is (i) active recall on the high pressure fuel pump (but not on my vin) and (ii) direct impact of replacing regular fuel pump on leading to high pressure fuel pump failure, as my vin is not currently acknowledged, my repairs would not be covered. I would like to request that the scope of the VIN numbers be re-evaluated and secondly the impact of fuel pumps replacement leading to other fuel pump be evaluated such that the recall work can cover both issues related to the rod bearing.

High pressure fuel pump failure. Car not functional and every warning light started to light up. The car just was serviced for rod bearing (entire crank shaft needed replacement) and regular fuel pump recall replacement which took the dealership almost a month to complete. I spoke to Acura representative who indicated that when either of the fuel pump or high pressure fuel pump is replaced, the other pump could fail. I'm not sure why both of the fuel pumps (standard and high) are not both replaced as part of the recall if there is substantial damage as was my case. Also, please note that there is an active high pressure fuel pump recall on my car, just not my vin.

1. Fuel pump module and engine crankshaft. 2. For the fuel pump module, the engine may not start or can stall while driving; increasing the risk of crashing or injury. For the engine crankshaft, the connecting rod bearing can prematurely wear and seize, causing engine damage. The damaged engine may run improperly or stall while driving, increasing the risk of a fire, crash, or injury. 3. The problem hasn’t been reproduced or confirmed by the dealer. 4. The vehicle hasn’t been inspected. 5. There were no warning signs. I have received letters in mail regarding the recalls, however the dealership has advised the first available appointment to service my car is September 2025.

My engine is starting to make a knocking/ticking noise, related to this recall. Very unuasal for a car with 65K miles. My local Acura dealers continue to tell me their waiting on parts??? Both recalls are almost 1 years old. How long should a consumer wait for a known manufacturers defect?
