- The engine system failed and it is available for inspection -While driving on the highway at normal traffic speed, my vehicle suddenly developed a loud knocking noise and the check engine light lit up. Within moments, the engine lost power and became inoperable, leaving me unable to continue driving while being 300 miles away from home. This incident occurred at about 5-6AM, having to maneuver through traffic before the sunrise. This created a serious safety risk because surrounding vehicles were traveling at full speed increasing the risk of collision. There were no warning signs of this failure and I was unfortunately stranded on the highway in an unfamiliar town for hours with minors in the vehicle. -Yes, the vehicle was towed to a local dealeriship, Hahira Automotive Services, where the engine failure occurred and they confirmed that they were unable to start the car and the knocking sound was indicative of engine failure. I towed the car to an Acura dealership local to my home and they confirmed the same vehicle condition and that a takedown is required to fully inspect the engine. -The engine has not been inspected by anyone only the vehicle condition -There were no warning signs of engine failure prior to the incident

This vehicle was sold to me on July 18, 2025 with Campaign CH7 open and unperformed. The dealer's disclosure form falsely stated that I had been informed of all recalls with the vehicle. No specific mention of Campaign CH7 was ever made. Separately, Acura manufacturer records (eVRM/Techline) confirm that this vehicle's original engine was previously replaced under warranty following a seizure (Defect Code: SEIZED) — directly related to the defect type covered by the CH7 recall. The replacement engine subsequently seized approximately eight months after I purchased the vehicle. I am requesting the federal safety agency investigate whether the open Campaign CH7 recall contributed to the engine failure, and whether FSL Motors' practice of selling vehicles with open recalls while falsely certifying recall disclosure warrants further review.

I bought my 2018 Acura TLX a-spec V6 in Nov. 2021, certified pre-owned from an Acura dealer. It had warranty through 100k miles. At just under 70k miles, around mid-2023 I believe, the engine seized and would not start. Warranty covered engine replacement. This was just around the time of the 3.6L V6 engine recall. I waited on the recall because the engine was brand new at that point. A year or so later, deal did inspect the engine for recall, but determined it was not part of the recall. Come current to late April 2026, just before engine #2 hit 70k miles (total miles on car ~139,000), engine has seized again. Driving on freeway and car went into limp mode, thankfully close to home and made it safely. Had car towed next day to mechanic who sent a video of the knocking noise (can send video if requested; unable to upload here) and refused to work on it. He later drove the car down the block and that is when engine completely failed; no longer would turn on. Towed home, towed to dealer a week ½ later when they had opening. Dealer performed diagnostic and confirmed crankshaft seized. However, now, well past warranty coverage. I called Acura customer relations and opened a case; they will only cover "half" of the engine replacement, at a cost of $13,817 to me. My car is less than 10 years old, less than 150k miles overall and should NOT need engine #3. Will same issue happen after another 70k miles? Acura refuses to acknowledge and take care of it 100%.

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.

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.
