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.

The contact owns a 2019 Acura TLX. The contact stated the vehicle was recently taken to a local dealer and was repaired under a recall for the fuel pump. The contact stated that on a separate occasion, while stopped at a red light, the vehicle stalled. The contact was able to restart the vehicle. The vehicle was taken to the dealer, and it was determined that the second fuel pump had failed and needed to be replaced. The contact was informed that there would be a cost for the repairs since the failure was related to the second fuel pump and not the fuel pump that was recently replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

On several occasions I have experienced issues with the performance of my vehicle. Upon start up and attempting to move forward while the car is in drive the vehicle hesitates to move and feels like it is going to choke and stop.

There is an open recall for 2015-20 TLX no SH-AWD Fuel Pump Mtr Saf Recall Exp2, RECALL DATE:12/18/2023 which has yet to be fixed.

The car will stall. The auto start/stop does not turn the car back on. The car fails to start sometimes when trying to leave. We have almost been rear ended multiple times, the transmission stalls and will not “go” when you press the gas or the car won’t even turn back on. We have contacted Acura and a local dealer. Both say they do not have a remedy for this issue yet even though it’s part of the recall and keep pushing it off to the next season. Each time I call for an inspection, I get told there is nothing they can do. I ask about seeking legal advice and they just tell me they don’t have a remedy so a lawyer can not help me.

My engine shuts off while idling, shifts into neutral automatically, and stalls when sitting at a light. This is a huge safety concern for me. My fuel pressure light and battery comes on when it shuts off.

My car stalled for the second time on june 12, 2019. First time was march 31, 2019. Since I already got the recall notice (the federal safety agency recall 19v‑060) before the first time, I took it to the dealer and they said they fixed the issue by doing a software update. However, even after the software update, it stalled again on june 12th, 2019. It looks like either a new issue or their software update did not fix it. There is also a possibility of the updated software having new bugs. In my car, the issue could be with the computer, or other electronics or mechanical defects which acura has not been able to find out during my several visits to their service. This is because most or all features of the car have been malfunctioning eversince I leased it. Another big issue is, apparently, the car computer did not record the stalling that happened on march 31st. Therefore, it looks like my car has a bigger issue than just software. The car (2019 acura tlx) has numerous issues ever since I leased it in september 2018 and they all continue. I have taken it to the dealer several times and none of the issues had been fixed. All features on the car malfunction and cause distraction while driving. The safety features not only don't serve the purpose of safety, but malfunction instead causing distraction and are very unsafe. The car would have been safer without these malfunctioning safety features. Acura has not fixed any of these malfunctions, although I have visited the dealer several times. To top that the car stalled twice which is even more serious. Although, my appointment is for 6/24/19 (I could not get an earlier one since they don't seem to take it seriously), the customer service rep called me a few days after scheduling it and said she did not expect it to help. I will still keep the appointment, even though the rep indicated this stalling will be dismissed as nothing.
